Connect the invoice to the work.

Issuing a document is only one part of invoicing. Your team needs to identify what was billed, which reference applies and how a payment changes the outstanding record. We scope the connection around that operational chain.

Confirm the interfaces

We inspect the supported accounting, bank or payment-provider interfaces and the business-owned accounts involved. Data ownership, reference matching and the handling of delayed responses are agreed before implementation.

QR-bill work needs the specification

Where a Swiss QR-bill is relevant, the current SIX implementation guidelines and your banking arrangements guide the technical scope. We confirm the version, fields and validation approach rather than treating a QR image as proof of a valid invoice.

Reconcile the difficult cases

Test examples include partial payment, duplicate notifications, unmatched references and a corrected invoice. Accounting decisions and fiscal advice stay with your responsible professionals. Provider eligibility and fees are confirmed separately; no particular method is promised without the required access.
