PromptPay QR

Let clients scan and pay from the invoice

Set your PromptPay ID once. Flowly adds the QR to every invoice so clients pay faster with fewer bank-detail mistakes.

What it does

QR matches the invoice total

Clients see the VAT/WHT-adjusted total and scan the right amount without copying bank numbers.

Personal or business PromptPay

Use a phone number or tax ID, saved once in business settings.

Works well with LINE delivery

Download the PDF and send it through LINE, email, or WhatsApp. Clients open and pay.

Payment status in one place

When money arrives, mark the invoice as paid and issue a receipt from the same record.

Frequently asked questions

Does Flowly generate the QR from the invoice total?

Yes. Flowly uses the net amount on the invoice to generate a scannable PromptPay QR.

What if the client transfers the wrong amount?

Check your bank as usual. Mark the invoice paid only when the received amount is correct.

Can I use this after a quotation is approved?

Yes. Convert the quotation into an invoice, then send the PDF with the QR.
