Questions

The questions people ask before they send an invoice

Each page takes one question, answers it in the first paragraph, then answers every other way people ask it. The tables and tools are further down, for when you want to apply the answer.

Purchase orders

What is a purchase order?

What a PO and a PO number are, who issues them, and what happens to an invoice that does not match one. Written for the person sending the invoice.

Invoicing a client abroad

How do I invoice a client in another country?

Currency, bank details a foreign bank can use, IBAN vs SWIFT, and whether to charge VAT, with a country-by-country table of what a payer needs.

Looking for something that went wrong with an invoice you already sent? That is what Answers is for. Help with the product itself is in the FAQ.
