How is the Shopify Uyumsoft integration done?

Setup starts by discovering which Uyumsoft product is open: e-Dönüşüm, Uyum ERP, or both. Then the GİB registration and the credit pack are confirmed, access is prepared if ERP is in place, account and series matching are built, and the shipping line and return rule are written down. The last step is a test order with a single product producing a document on the right series.

Is connecting e-invoice alone enough?

Yes, if you want a legal document from the order. If you will also manage stock, price and the warehouse split from Uyumsoft, Uyum ERP has to be open and that side has to be set up separately.

Are Uyumsoft e-fatura and e-arşiv issued automatically on a Shopify order?

They are, once the bridge is built. The document is created inside Uyumsoft, goes to GİB on the special-integrator infrastructure, and the number comes back. If the buyer is an e-fatura taxpayer an e-fatura is issued, otherwise an e-arşiv. Shopify's own output does not stand in for that document.

Is a separate series required for internet-sale invoices?

It is. Documents for sales made over the internet are written to a series different from your other invoices. This split is built at the very start of the document layout; the series of a past document cannot be changed later.

Which details must be present on an internet-sale invoice?

The web address where the sale was made, the payment method, the organization that mediated the payment, the payment date, the tax or identity number of the party that carried the goods, the date the goods were sent, a returns section and a statement that the sale was made over the internet. The paper copy of the invoice also travels with the shipped goods.

How are corporate invoice details collected?

Shopify checkout does not collect tax ID, tax office or legal title by default. If those fields are missing, Uyumsoft treats every order as a final consumer. If you sell to businesses, where those details are collected in the payment flow is solved during setup.

Is stock written from Uyumsoft to Shopify?

It is written when Uyum ERP is open; the catalog's truth then sits in Uyumsoft. There is no stock flow on an e-Dönüşüm contract alone, and the catalog keeps living in Shopify.

Which warehouse's stock is opened to the store?

The decision is made in the ERP setup. Opening only the ecommerce warehouse is the safest path. Writing the sum of more than one warehouse collides with store sales. When the decision is changed later, the catalog and the order flow change too.

Which field are products matched on?

Matching is not built on the title. When ERP is open, barcode or stock code is used. Mixing a pack barcode with a single-sale barcode breaks stock silently.

How do variants sit in Uyumsoft?

The vendor's own text does not describe a native variant model like Shopify's. The practical expectation is a separate stock card for every color and size combination. That is not a rule; it is confirmed with a test record.

Are cancellation and return the same document?

They are not. The cancellation window is short, after that a return invoice. When the window has passed, the correction is made with a new document and the two documents are offset. Sources disagree on the number of days, so a day count is not given.

Is an order written into a closed period?

It is not. If an order that lands near month end sits in the queue while the period closes, the record is refused. The bridge turning that into an alert is part of the setup; otherwise the loss stays silent.

My marketplace invoices already leave from Uyumsoft. Is Shopify set up separately?

It is set up as an extra channel on the same seal; you do not need to pick a separate integrator. The job of setup is that the same order is not documented twice, that the account is not opened twice across channels, and that the credit pool can carry both sources.

How does a foreign-currency sale land on the invoice?

Shopify can sell in more than one currency; the accounting record enters after conversion into local currency. If which day's rate is used is not set up, reconciliation breaks every month with small differences.

Is the shipping charge added to the invoice?

Whether it is added, and at what rate, is defined during setup. The rate is not assumed; it is seen on a test document. The wrong rate produces a VAT difference at month end.

Shopify Uyumsoft Integration

Q: Does Uyumsoft have an official Shopify app?

Uyumsoft has no app that it publishes itself in the Shopify app store. The bridge is built from an integration tool or a project-specific middle layer. No ready-made connector announcement that names Shopify was found on Uyumsoft's site in this review.

Q: Are Uyumsoft e-invoice and Uyum ERP the same thing?

They are not. e-Dönüşüm is GİB-approved special integration, and its job is to seal the legal document. Uyum ERP carries stock, accounts, orders and finance. Many stores only need the first; syncing stock wants the second product.

Q: What are credits, and how do they affect the integration?

On Uyumsoft, sending an official document drops credits. When the pack runs out, no new document is issued, and in most setups this happens silently. Credits are not a model where every stock query is billed; they are planned against monthly document volume.

Uyumsoft is not a single product: GİB-approved special integrator services and Uyum ERP sit under the same brand. On the Shopify side, an Uyumsoft connection usually means turning an order into an e-invoice or e-archive invoice; syncing stock and price only becomes possible once the ERP side is active. Setup starts with identifying which product is actually in use, the bridge is built from a dedicated integration tool rather than an app published by Uyumsoft itself, and online sales invoices run on their own series.

Shopify Uyumsoft integration what is it?

Shopify Uyumsoft integration is the connection that turns a store order into a record on the Uyumsoft side and issues the legal document from there. If you only hold an e-Transformation agreement, the flow is order, ledger account, invoice. If Uyum ERP is also active, stock and price get written back to the store from Uyumsoft.

Setup starts by identifying which Uyumsoft product is actually in use. On the integrator side, the GİB registration and the document credit package are confirmed; on the ERP side, access and licensing are cleared separately. Uyumsoft has no app of its own in the Shopify App Store, so the bridge is built through whichever integration tool you use.

Once the connection is live, the daily flow runs from one place: the order lands in Uyumsoft, a ledger account is opened or matched, and the document is issued with Uyumsoft's own stamp. If your marketplace invoices already run through the same stamp, Shopify just adds another channel to that same table; making sure the same order doesn't produce two documents is solved during setup.

WHAT GETS SYNCED

What gets synced between Shopify and Uyumsoft

Which items sync depends on which product you hold. The six items below cover the most common questions in a Shopify Uyumsoft integration; stock and price only come into play once the ERP side is active.

Shopify orders transferred to Uyumsoft

When an order is placed in the store, it's written to Uyumsoft. In a setup that only uses the integrator, this record is the source of the document; with ERP active, a sales order record is also created and the invoice is generated from it.

Ledger account creation and matching

The buyer's details turn into a ledger account: if one already exists it's matched, otherwise a new one is opened. If the matching field is set up wrong, a second account gets created for the same person and has to be merged by hand.

e-invoice and e-archive invoice stamp

The document goes to GİB through Uyumsoft's special integrator infrastructure. If the buyer is an e-invoice taxpayer they get an e-invoice, otherwise an e-archive invoice is issued. Shopify's own order confirmation does not replace this document.

Stock and price written back to the store

This item only runs once Uyum ERP is active. From that point, the real catalog lives in Uyumsoft; which warehouse and which price list feed the store is the critical decision in setup. An e-Transformation-only agreement doesn't include this flow at all.

Online sales invoice series

Documents for sales made online cannot share a series with in-store or wholesale sales. The series is opened at the very start of Uyumsoft's document structure; a past document's series cannot be changed afterward.

Cancellation and return documents

The cancellation window is short; after it closes, a return invoice is the only option. Assuming a return equals a cancellation doesn't hold up by month end — the two documents have to be offset against each other. Since sources disagree on the exact number of days, it isn't stated here; confirm it with your Uyumsoft account manager.

TWO PRODUCTS

Which Uyumsoft product does the integration connect to?

Two separate products sit under the same brand. If this distinction isn't made clear on day one of setup, every step after it builds on the wrong expectation.

e-Transformation: stamps and archiving

GİB-approved special integrator services sit here. e-invoice, e-archive invoice, e-waybill and e-ledger are all issued from Uyumsoft's infrastructure. For many Shopify stores this is the only real need: turning an order into a legal document.

Uyum ERP: stock, ledger, orders

The ERP side carries production, stock, finance and the ledger. Writing stock and price to the store, choosing warehouse splits and price lists — all of that decision-making happens here. Without ERP, none of these items connect.

Hosting depends on the product

e-Transformation is a cloud service; no on-premise server sits in the middle. Uyum ERP can run either in the cloud or on your own server; a server-based setup needs a secure access path opened separately.

Credits are tied to documents

Sending an official document consumes credits. This isn't a model where every stock lookup costs something; once a package runs out, no new document is issued. Packages are sized against your monthly order volume.

Uyumsoft doesn't publish the bridge itself

Uyumsoft has no app of its own in the Shopify App Store. The connection is built through an integration tool or a project-specific middle layer; the boundary of responsibility is set out in the agreement.

If a marketplace stamp is already there

If your Trendyol or Hepsiburada invoices already come out of Uyumsoft, Shopify just becomes another channel feeding the same stamp. Preventing the same order from producing two documents, or the same customer from getting two ledger accounts, is solved at this stage.

In practice, the first question in a setup meeting is the license list. If you only hold a special integrator agreement, this page is your invoice bridge. If ERP is also in place, stock and price are designed separately. Treating the two as one story ends up getting the project built twice.

SETUP

How is Shopify Uyumsoft integration set up?

The six steps below cover setup from identifying the product to the first test document. Skip the first step and the other five get built against the wrong product.

Identify which Uyumsoft product is active

Is it an e-Transformation agreement, Uyum ERP, or both? Clarify this with your Uyumsoft partner at uyumsoft.com. This list determines which document and which record gets transferred.

Confirm the GİB registration and credit package

On the special integrator side, confirm that your tax registration runs through Uyumsoft and that the credit package covers your monthly document volume. Once a package runs out, no new document is issued — this happens quietly in most setups.

If you use ERP, prepare access

Cloud ERP doesn't need a server in the middle. In a server-based setup, a secure access path is opened, and which company and which period the bridge writes to is decided. Once a period is closed, no records land in it.

Define ledger, product and series matching

Write down which field matches the customer to a ledger account, whether products match by barcode or SKU, and which invoice series is used for online sales. If you sell to businesses, this step also settles where the tax ID and company name are collected during checkout.

Set up the shipping line, currency and return rule

Whether shipping cost is added to the invoice as a line item, and at what rate, is defined in setup — the rate isn't guessed, it's confirmed with a test document. If you sell in foreign currency, which day's exchange rate applies is written down. A return issued after the cancellation window closes is set up as a separate flow.

Verify the document and stock with a single order

Place a single-item order and confirm the record lands in Uyumsoft, the ledger account opens correctly, and the document comes out with the right series and the right stamp. If ERP is active, also check that stock drops in the store in the same test. If you have marketplace channels, check that the same order doesn't produce a second document.

The table below shows what each Shopify record maps to on the Uyumsoft side. The stock and price rows only fill in once ERP is active.

What's in Shopify	Its counterpart in Uyumsoft
Order	Document source; a sales order record too, if ERP is active
Customer	Ledger account; the matching field is chosen during setup
Product	Stock card, once ERP is active
Variant	Expected as a separate stock card; the vendor's rule here isn't clearly documented
Price	The selected price list, ERP only
Stock	Quantity in the selected warehouse, ERP only
Invoice	e-invoice or e-archive invoice, with Uyumsoft's stamp
Return	Return document or cancellation, depending on timing
No counterpart	Tax ID and company name; credit balance; company and period

The table's last row lists three items Shopify doesn't hold natively. If the tax ID isn't collected at checkout, every order is treated as a final consumer sale. Credit balance is only tracked on the Uyumsoft side. Company and period settings determine which taxpayer a record is written under in an ERP setup.

WHICH PRODUCT

Invoicing only, or stock too?

In most stores, an Uyumsoft search boils down to one expectation: when an order comes in, a legal document should follow. An e-Transformation agreement covers exactly that. Stock, price and warehouse splits are a separate product, and set up separately.

In a store where only the document bridge is set up, the catalog keeps living in Shopify. Uyumsoft doesn't hold stock, manage a price list, or carry the variant matrix in that setup. All that's expected is that the order turns into a ledger account and a document.

Once Uyum ERP is active, the direction reverses: the real catalog lives in Uyumsoft, and the store just publishes it. Which warehouse goes online and which price list feeds the site is decided at this point. Connect the wrong store list and the wrong price goes live.

When both products are in play, order matters. The document series, ledger matching and GİB stamp go live first; writing stock to the store is the second wave. Turning both on the same day is how the wrong warehouse or the wrong list ends up live.

INVOICING

How is the online sales invoice issued in Uyumsoft?

The document comes out of Uyumsoft, not Shopify. The six points below come straight from regulation; the system's name changes, the rule doesn't.

Online sales need their own series

Shopify orders can't share a series with in-store or wholesale sales. The series is opened at the very start of Uyumsoft's document structure. A past document's series cannot be changed afterward.

The invoice has mandatory fields

The invoice must include the website the sale was made on, the payment method, the payment intermediary, the payment date, the tax or ID number of whoever carried the goods, the shipping date, a returns section, and a statement that the sale was made online. If the transfer can't read these from the order, the field is left blank.

A paper copy travels with the goods

A printed copy of the invoice travels with the shipped goods; the store's packing slip doesn't replace it. The rule changes the packing station, not the accounting: the label and the invoice printout get pulled at the same step.

The cancellation window is short; after it, a return document

Once the window passes, a correction is made with a new document, not a cancellation, and the two documents are offset against each other. The exact number of days isn't stated here since sources disagree. Assuming a return equals a cancellation doesn't hold up by month end.

No record lands in a closed period

If an order sits in the queue near month end and the period closes, the record gets rejected — this happens quietly in most setups. Having the bridge raise an alert when it fails is part of the setup.

Shopify's confirmation isn't the invoice

The legal document always comes out of Uyumsoft. The integration's job isn't to send the customer some output — it's to issue the document from the right series, at the right rate.

Business invoice details (tax ID, tax office, company name) aren't collected by default at Shopify checkout. Without these fields, Uyumsoft treats every order as a final consumer sale. If you sell to businesses, where this information gets collected is worked out during setup.

MATCHING

How are the ledger, product and variant matched?

Because the bridge opens a ledger account from every order, a wrong matching field lets that table balloon. In Uyumsoft, merging duplicates afterward is a manual job.

Duplicate ledger accounts

The same person creates a second account when they show up with a different email, phone number, or as a guest order. A separate rule is set for guest orders; otherwise the ledger list becomes unreadable by month end.

Products don't match by name

Titles change, barcodes don't. With ERP active, matching runs on barcode or SKU. Mixing up a case barcode with a single-unit sales barcode breaks stock quietly.

Variant mapping isn't clearly published

Uyumsoft's own documentation doesn't officially describe a built-in variant model like Shopify's. The practical expectation is a separate stock card per color and size; that's not a documented rule, it's something you confirm with a test record.

The exchange rate decision is written down

Shopify can sell in multiple currencies, but the accounting record is entered converted to local currency. If which day's rate applies isn't defined, reconciliation drifts by small amounts every month.

Tax on the shipping line

Whether shipping cost is added to the invoice as a line item, and at what rate, is defined during setup. The rate isn't guessed — it's confirmed with a test document.

Marketing copy doesn't live in ERP

Search copy, collection structure and storefront descriptions aren't stored in Uyumsoft. If the transfer overwrites these fields, weeks of writing disappear in a single sync; the fields to protect are flagged in advance.

MULTI-CHANNEL

If marketplace invoices already come out of Uyumsoft

In many brands, Uyumsoft was originally chosen for marketplace invoicing. Once Shopify is added later, the same stamp has to handle two sources at once.

A second channel into the same stamp

If Trendyol and Hepsiburada orders are already documented through Uyumsoft, Shopify gets written into the same infrastructure. The upside is a single archive and a single credit pool. The risk is the same order getting documented twice by two separate transfers.

Duplicate ledger accounts

A marketplace customer is usually opened under the marketplace order number, a Shopify customer under their email. When the same person shops on both channels, two ledger accounts get created. Without a matching rule shared across channels, reports balloon.

Stock gets reserved twice

With ERP active, the marketplace transfer and the Shopify transfer can each deduct from the same warehouse separately. Review the existing reservation rule before adding a new channel.

One shared credit pool

Document credits aren't split by channel. On a heavy campaign day, marketplace and Shopify orders drain the same package together; once it's gone, no new document is issued. Monitoring only looks at one balance.

Returns get documented per channel

A marketplace return follows the marketplace's own rule, a Shopify return follows the store's rule. Both produce a document in Uyumsoft, but the source order number is different. Offsetting is therefore set up with a channel tag.

Watching it from one screen

Two sources writing into the same stamp means you need to see the order and the document side by side. That's what Station is for: which channel produced which document sits on one screen.

SCENARIO

Three common problems and how we fixed them

The three setups below show how we've handled Shopify Uyumsoft integration issues in stores we've connected.

Assuming stock would sync too while waiting for documents

Problem The store was connected to Uyumsoft and orders were turning into documents, but stock on the site was still updated by hand. The team thought the integration was half-finished.

Cause They only held an e-Transformation agreement. With Uyum ERP not active, stock and price were never meant to be written from Uyumsoft to the store — the bridge was producing documents exactly as designed, nothing more.

Fix We clarified the scope: the document bridge and the stock bridge are separate. Since stock sync was actually wanted, the ERP license and warehouse decision were planned as a second, separate project. The existing document flow was left untouched.

Every business order showing up as a final consumer sale

Problem By month end, Uyumsoft's ledger accounts were full of personal names; invoiced companies had no tax ID on the document. Accounting was correcting every record by hand.

Cause Shopify checkout wasn't collecting the tax ID, tax office, or company name. The transfer wrote the blank field to Uyumsoft as a final consumer sale.

Fix Business-info fields were added to checkout, and the matching rule for existing ledger accounts was switched from email to tax ID. New business orders started producing documents under the correct company name.

The marketplace and Shopify documenting the same order twice

Problem On a campaign day, some orders ended up with two documents in Uyumsoft. Credits ran out faster than expected, and the customer received two document numbers.

Cause The marketplace transfer and the Shopify transfer were both writing to the same stamp without sharing the order number — the same basket was being read as two separate sources.

Fix Source-tagged deduplication was set up: the marketplace order number or the Shopify order number became the document key. The second write was rejected, and credit consumption returned to normal.

STATION

Shopify Uyumsoft integration

Station is the tool we built to watch orders, stock, price and invoicing from a single panel. If your marketplace channels also write into the same Uyumsoft stamp, this is where you catch the duplicate-document risk.

FAQ

Frequently Asked Questions

How is Shopify Uyumsoft integration set up?

Setup starts by identifying which Uyumsoft product is active: e-Transformation, Uyum ERP, or both. Then the GİB registration and credit package are confirmed, access is prepared if ERP is involved, ledger and series matching are configured, and the shipping line and return rule are written down. The final step is a single test order producing a document from the correct series.

Does Uyumsoft have an official Shopify app?

Uyumsoft has no app of its own published in the Shopify App Store. The bridge is built through an integration tool or a project-specific middle layer. No ready-made connector mentioning Shopify was found on Uyumsoft's own site as of this review.

Are Uyumsoft e-invoice and Uyum ERP the same thing?

No. e-Transformation is the GİB-approved special integrator service, and its job is stamping the legal document. Uyum ERP carries stock, ledger, orders and finance. Many stores only need the first one; syncing stock requires the second product.

Is connecting only e-invoice enough?

Yes, if all you want is a legal document generated from each order. If you also want to manage stock, price and warehouse splits from Uyumsoft, Uyum ERP needs to be active and set up separately.

Are Uyumsoft e-invoice and e-archive invoice issued automatically on Shopify orders?

Yes, once the bridge is set up. The document is created inside Uyumsoft, goes to GİB through the special integrator infrastructure, and the document number comes back. If the buyer is an e-invoice taxpayer they get an e-invoice, otherwise an e-archive invoice. Shopify's own confirmation does not replace this document.

Does the online sales invoice need its own series?

Yes. Documents for sales made online are written to a different series from your other invoices. This distinction is set up at the very start of your document structure; a past document's series cannot be changed afterward.

What information must appear on the online sales invoice?

The website the sale was made on, the payment method, the payment intermediary, the payment date, the tax or ID number of whoever carried the goods, the shipping date, a returns section, and a statement that the sale was made online. A printed copy of the invoice also has to travel with the shipped goods.

How is business invoice information collected?

Shopify checkout doesn't collect tax ID, tax office or company name by default. Without these fields, Uyumsoft treats every order as a final consumer sale. If you sell to businesses, where this information gets collected in the checkout flow is worked out during setup.

What are credits, and how do they affect the integration?

Sending an official document through Uyumsoft consumes credits. Once a package runs out, no new document is issued — this happens quietly in most setups. Credits aren't a model where every stock lookup costs something; they're sized against monthly document volume.

Does stock get written from Uyumsoft to Shopify?

Yes, once Uyum ERP is active — the real catalog then lives in Uyumsoft. An e-Transformation-only agreement has no stock flow at all; the catalog keeps living in Shopify.

Which warehouse's stock gets exposed to the store?

That decision is made during ERP setup. Exposing only the e-commerce warehouse is the safest route. Writing the combined total of multiple warehouses conflicts with in-store sales. Changing this decision later also changes the catalog and order flow.

Which field do products match on?

Matching isn't set up by title. With ERP active, barcode or SKU is used. Mixing up a case barcode with a single-unit sales barcode breaks stock quietly.

How are variants represented in Uyumsoft?

The vendor's own documentation doesn't describe a built-in variant model like Shopify's. The practical expectation is a separate stock card per color-and-size combination. That's not a documented rule — it's confirmed with a test record.

Are a cancellation and a return the same document?

No. The cancellation window is short; after it, you're issuing a return invoice. Once the window passes, the correction is made with a new document and the two are offset against each other. The exact number of days isn't stated here since sources disagree.

Can an order be written into a closed period?

No. If an order sits in the queue near month end and the period closes, the record is rejected. Having the bridge turn this into an alert is part of setup; otherwise the loss stays silent.

My marketplace invoices already come out of Uyumsoft — is Shopify set up separately?

It's set up as an additional channel into the same stamp; you don't need a separate integrator. Setup's job is making sure the same order isn't documented twice, the ledger account isn't opened twice across channels, and the shared credit pool covers both sources.

What changes if Uyumsoft runs on our own server?

e-Transformation is cloud-based; no server sits in the middle. If Uyum ERP runs on your own server, a secure access path is opened and the bridge connects to that address. This step doesn't exist with cloud ERP.

How long does the integration take?

This is a project timeline, not a single setup day. Four things determine the duration: product identification, GİB and credit verification, ledger and series matching, and — if ERP is involved — the access path. With server-based ERP, most of the first week goes into access.

How does a foreign-currency sale show up on the invoice?

Is the shipping fee added to the invoice?

Whether it's added, and at what rate, is defined during setup. The rate isn't guessed — it's confirmed with a test document. A wrong rate produces a VAT discrepancy by month end.
