Plans and billing
Change your card or billing details
Update the card we charge from your billing page, through Stripe's secure billing page. We never see or store your card number.
Update your card
- Go to your billing page.
- Click Card, invoices & receipts. This opens Stripe's secure billing page.
- Add the new card and make it your default.
- Return to CompanyStack.
The new card is used for your next payment. If a payment is overdue, you can pay it at once with Pay now in the Invoices section of the billing page.
The Card, invoices & receipts button appears once you have paid for a plan.
One card for everything
One Stripe customer record holds all your subscriptions: the web app and the API. The card you set is used for each of them.
Payment methods we accept
We take card payments through Stripe, in pounds sterling. We do not take bank transfers, direct debits or cheques for self-serve plans.
Your card details are safe
You enter your card number on Stripe's pages. It never reaches our servers. We see only the last four digits and the expiry date.
We will never ask for your full card number, by email or any other way. If a message claiming to be from us does, do not reply. Forward it to support@companystack.co.uk.
