Does this replace our accounting?

No. It produces the document and records what was paid. Accounting stays where it is — it simply receives clean documents instead of spreadsheets.

What happens if a payment notification arrives twice?

It is recognised as already recorded. The provider's transaction id may appear only once in the system; the second arrival goes nowhere instead of creating a second payment.

From when can an invoice be generated?

From approval of the order. Before that there is no document, because there are no binding line items yet.

How does payment relate to the discount?

The customer's volume tier follows the quantity actually paid for that month. The current order does not count towards its own tier — otherwise an order could make itself cheaper.

Can we keep our own invoice layout?

Yes. Sender, bank details and layout information live in the company's administration and appear on every document.

Invoicing and payment in window manufacturing

The short answer

The invoice is generated from the approved order, in the company's own layout, with the order number as the document number. Payment is by card or bank debit, and every payment is attached to the order it belongs to.

The unremarkable part is reconciliation. Payment providers occasionally report the same event more than once — after a dropped connection, a retry, a delayed confirmation. Post it twice and the receivables list stops being true, which surfaces only when a reminder goes out.

How it runs

From approved order to paid invoice

Five steps that all point at the same order.

Invoice out of the order

It is generated from the point the order is approved — a PDF in your own layout, with the line items that also went into production. No second entry and no diverging total.

Card and bank debit

Both routes lead to the same invoice. Bank debit takes longer to confirm than a card; meanwhile the order shows the actual state rather than an assumption.

Reconciliation without double posting

Every payment is recorded under the provider's transaction id, and that id may exist only once. If the same notification arrives again, the system recognises it as already recorded — without anyone checking a list.

Payment mark on the order

Whether and when payment came in sits on the order, not in a separate accounting state. Whoever looks at the order sees its payment state too.

Basis of the volume tier

What counts towards the customer's tier is what was actually paid that month. The discount is therefore a consequence of business done, not of a promise someone remembers.

Why the document belongs to the order

An invoice created elsewhere is a second truth. As soon as a line changes in the order after the invoice was written, there are two numbers and nobody who can say which one holds. When the document comes out of the order, that question cannot arise.

The same goes for the question from accounting. "What was this payment for?" is a search when payment and order live apart — and a single line when they do not.
