The short answer

Logo Shopify integration is the automatic transfer of material cards, stock and prices from Logo ERP to your Shopify store, and of Shopify orders, customers and payments into Logo as sales order slips, customer accounts and invoices. The connection is built through a middleware layer between Logo's REST service or Logo Objects and the Shopify GraphQL Admin API and webhooks.

Logo Tiger, Logo Go, Netsis and j-Platform each use a different integration interface, so the right method depends on the product you run. A standard B2C store typically goes live in 6–10 weeks; projects with B2B or multiple warehouses take 10–16 weeks.

This guide draws on the field experience of Byte Digital, a Shopify Plus Partner that has served Shopify brands for 7 years.

Which data is synchronised between Logo and Shopify?

Materials, stock and prices flow from Logo to Shopify; orders, customer accounts and payments flow from Shopify to Logo. On the Logo side, decide up front which slip type each piece of data becomes.

Which Logo product do you use?

Logo is a product family rather than a single product; the path to a Shopify integration depends on which one you run.

Logo's REST library states that the Tiger REST service offers read-write and query operations on Logo Objects data objects, while direct insert/update queries against the database are not recommended for security reasons (Logo REST library). Logo publishes a separate REST service for j-Platform (j-Platform REST).

In practice the rule is simple: SQL views can be used to read from Logo, but writing to Logo must always go through Logo Objects or the REST service.

Logo Shopify integration methods

A Logo-approved integrator suits a standard B2C flow; a multichannel platform suits brands also connecting marketplaces; custom middleware is the right choice when there is B2B or bespoke business logic.

Logo Objects is a component that runs on the Windows server where Logo is installed. For on-premise Logo installations, part of the middleware therefore runs on the company network close to the Logo server and talks to Shopify over a secure connection. Where the REST service is enabled, the connection can be made directly over HTTPS. Either way, the middleware should include an order queue, automatic retries and an error dashboard.

Logo-specific decisions in a Logo Shopify integration

The success of a Logo integration depends more on accounting decisions than on technology; the five questions below should be answered with your accountant and finance team before the project starts.

• A separate customer account per buyer, or one e-commerce account? Individual buyers can be booked to a single "e-commerce retail" account with invoice details kept on the slip, while corporate buyers should be opened as separate accounts by tax number. This decision directly affects the e-invoice / e-archive split.

• Order or direct invoice? Should a Shopify order land in Logo as a sales order and turn into a dispatch note and invoice after warehouse confirmation, or should an invoice be issued directly? An order slip is recommended for companies with a warehouse process.

• Which account receives payments? Define how payments from iyzico, PayTR or a bank virtual POS are posted on a credit card slip to which bank account, including commission and instalments.

• VAT and discounts: VAT-inclusive Shopify prices and line and document-level discounts must be distributed so that no rounding differences appear in Logo.

• Shipping fees: Shipping charged to the customer should be added to the invoice in Logo as a service card.

Logo Shopify integration step by step: timeline and cost

A standard B2C store goes live in 6–10 weeks; projects with B2B or multiple warehouses take 10–16 weeks.

1. Discovery (1 week): Logo product and version, company/period structure, warehouses, slip types and customer account strategy are defined.

2. Accounting decisions and mapping (1–2 weeks): Material codes are mapped to SKUs, warehouses to locations, payment methods to bank accounts, and VAT rates are aligned.

3. Development (2–6 weeks): Materials and stock first, then orders, customer accounts and payments, finally returns and invoicing.

4. Testing (1–3 weeks): End-to-end scenarios in a Logo test company; slip and account checks with the finance team.

5. Go-live and hypercare (2–4 weeks): A daily error report is tracked until the first month-end close.

The main cost drivers are the Logo product in use (Netsis and j-Platform require separate expertise), whether the REST service is licensed and enabled, the number of warehouses, B2B account and pricing structure, whether marketplaces are included in the same project, and any need for custom fields or reports on the Logo side.

The 6 most common mistakes in Logo Shopify integration

The most expensive mistakes are the ones discovered at month-end close, which is why the finance team must be part of testing.

1. Writing to the Logo database with SQL: Creating slips and customer accounts outside Logo Objects or the REST service corrupts balances, stock and cost calculations.

2. Opening an account for every individual buyer: Thousands of unnecessary account cards are created, and duplicates cause problems when sending e-invoices.

3. Forgetting company and period changes: If the integration settings are not updated when Logo moves to a new fiscal period, orders land in the old period.

4. Updating stock only overnight: Store and wholesale sales during the day are not reflected in Shopify, and out-of-stock items get sold.

5. Not booking instalment commissions separately: Payment amounts do not reconcile with the bank.

6. Ignoring rounding differences: If VAT-inclusive prices and percentage discounts are not rounded per line, the e-invoice total differs from the Shopify order total.

Frequently asked questions

Can Logo be integrated with Shopify?

Yes. Logo Tiger, Logo Go, Netsis and j-Platform can be integrated with Shopify through Logo Objects or Logo's REST services. Materials, stock and prices flow automatically from Logo to Shopify; orders, customer accounts and payments flow from Shopify to Logo.

How long does a Logo Shopify integration take?

For a standard B2C store, 6–10 weeks. Simple setups with a Logo ecosystem integrator take 2–6 weeks; projects with B2B and multiple warehouses take 10–16 weeks.

Do Shopify orders land in Logo as invoices?

It depends on your preference. In companies with a warehouse process, the order first lands as a sales order slip and becomes a dispatch note and invoice on shipment. Where no warehouse approval is needed, a sales invoice can be created directly.

How are e-invoices issued in a Logo Shopify integration?

e-Invoices and e-archive invoices are issued from Logo through the company's contracted e-transformation provider. The corporate buyer's company name, tax office and tax number must be passed from Shopify to Logo with the order.

Is there a difference between integrating Logo Go and Logo Tiger?

The integration logic is the same because the data structures are similar. The difference is that Tiger better supports multiple warehouses, advanced pricing and high-volume scenarios.

I use Netsis. Does the same integration apply?

No. Netsis's data model and integration layer differ from Tiger and Go, so a separate connection has to be developed for Netsis.
