Tax and invoices

Who bills you

Every STAK bill is issued by STAK Global, LLC. You pay it on Stripe's secure page, and you can download each paid bill as a PDF from the Bills tab (Open the Stripe invoice (PDF)).

Your bill numbers

Your bills are numbered for your business alone: STAK-, then your business's own six-character code, then a number that counts up from 0001, for example STAK-K7Q4M2-0001. Credit notes have their own series, for example STAK-K7Q4M2-CN-0001. The code is given at your first bill and never changes. The Bill column of the Bills tab shows each number.

Bills that were still unpaid when this numbering started were reissued under a new number, with the same lines, amount and due date. The old bill shows as Cancelled, and a pay link in an earlier email or text message opens the new bill.

Your registration number

Before your first paid plan, STAK asks for your commercial registration or licence number, or your country's equivalent. The Plan tab shows Add your registration number for your invoices until you do. It prints on your bills. If it doesn't look like the usual form in your country, STAK tells you; keep it if it is right.

Tax on your bill

Tax is already inside the price you see. When you pay, enter your VAT or tax ID on the payment page if you have one.

• In some countries STAK sells to businesses only, so a valid VAT or tax ID is needed. The Billing currency page tells you if yours is one of them.
• When your tax ID means you account for the VAT yourself (reverse charge), the bill says so and shows your tax ID.

Currency

STAK bills you in your country's currency, at fixed prices. Where the card network can't charge your currency, the bill is charged in US dollars at STAK's fixed rate, shown on the bill. You can change the billing currency once yourself, before your first bill.
