The invoice's supplier: why it matters more than it looks

Product mappings aren't stored "in general" — they're stored for a specific supplier. Milk from Makro and milk from Villa Market are two different mappings, even if it's the same product in iiko.

That's how it should be: different suppliers name the same item differently, and one shared dictionary would turn into a mess.

The main consequence#

If an invoice has the wrong supplier, you'll see empty lines — as if the service doesn't remember anything. The mappings are still there; the search just isn't looking in the right place.

This is the most common reason behind "matching stopped working."

How the supplier gets identified#

In order of reliability:

1. By the tax ID from the document.
2. By a spelling learned earlier.
3. By the name from the iiko directory.
4. By a similar name.
5. By a logo or brand on the letterhead.

Duplicate suppliers in iiko#

The most annoying case: the same vendor is entered twice in the iiko directory. Half the mappings pile up on one, half on the other, and invoices behave unpredictably.

The service doesn't create its own suppliers#

The supplier list comes entirely from iiko. If the one you need isn't there, create it in iiko first and update the reference data.

A supplier who sends invoices without prices#

Some suppliers (an in-house kitchen or warehouse, for example) send invoices that have no prices. On such a supplier's card, turn on the "Sends invoices without prices" switch: right after recognition, the empty prices are filled from past receipts. This supplier's own price is used first, and if there is none, any other supplier's. Printed prices are never changed, and filled-in ones get a "Price from a past receipt" mark. Without the switch, the button on the "The invoice has no prices" notice does the same thing.

Done. What's next?#

If the lines are still empty, let's go through it step by step.
