Every business that sells online has to issue an invoice for every order. As order volume grows, invoicing one by one wastes time and causes errors. E-invoice and e-archive integration makes sure invoices are created automatically and sent to the customer as soon as the order is completed.
E-invoice vs. e-archive invoice
- E-invoice: Used when the buyer is also registered in the e-invoice system; the invoice is exchanged electronically between two registered taxpayers. It is typical in B2B sales.
- E-archive invoice: Used when the buyer is not registered for e-invoicing, for example in sales to individual consumers. The invoice is delivered by email or similar electronic means.
A well-designed integration checks the buyer’s status and automatically decides which document type to issue.
How does the integration work?
- An order comes in from the website or a marketplace and is confirmed.
- The order is passed to the ERP and matched to a customer account.
- When the order ships, the invoice is created automatically through your contracted e-invoice integrator.
- The invoice PDF and link are sent to the customer and uploaded to the marketplace.
- The invoice record is posted to accounting with no manual work.
What to look for in an integrator
- Ready-made connections to your ERP and e-commerce platform,
- Clear and up-to-date API documentation,
- Performance for bulk invoice submission,
- The pricing model (per credit / per document),
- Speed of technical support.
Common mistakes
- VAT or rounding differences between invoice and order totals,
- Shipping fees and discounts not reflected correctly on the invoice,
- Return invoices and cancellation flows not defined,
- Forgetting to upload invoice details to the marketplace.
This process is a natural part of ERP and order management automation.
Frequently Asked Questions
Can marketplace orders be invoiced automatically too?
Yes. Trendyol, Hepsiburada and Amazon orders can be passed to the ERP through the integration and invoiced automatically, with invoice details sent back to the marketplace.
How should I keep up with regulatory changes?
E-document rules can change over time. Follow announcements from your integrator and your accountant, and make sure your integration can be adapted to updates quickly.
