Billing notes
Let accounts payable see the bill before it arrives.
Thai B2B teams expect a billing note before the real invoice. Flowly issues them in one minute and converts to the actual invoice when it's time to collect.
What it does
Pre-invoice notice
Not a demand for payment — a heads-up so finance can stage the payment before the invoice lands.
One-click convert to invoice
When it's time to collect, the same data becomes the real invoice — new number, same lines.
Every field accounting expects
Bill-to, line items, subtotal, VAT, total + payment terms.
Status: draft / sent / void
Paid status lives on the invoice that succeeds the billing note, not here.

Frequently asked questions
How is a billing note different from an invoice?
Billing note = advance notice; invoice = demand for payment. Billing notes don't count as VAT documents.
Should a billing note show VAT?
Yes, clearly — so the client can budget the right amount. But the billing note itself isn't a VAT tax invoice.
Can clients pay a billing note?
Not typically — their AP usually waits for the real invoice. Flowly's one-click convert keeps that workflow smooth.
