Payments are processed through Stripe. Each separate checkout creates its own Stripe customer record, which is why repeat purchases (for example, buying more mailboxes or replacement domains later) can appear as several charges that are not all grouped under a single invoice.
If you see multiple charges but cannot find a matching invoice or receipt for each one:
Contact support with your account email and the charge dates/amounts (or the receipt/charge IDs).
We will locate every Stripe record tied to your purchases and send you the missing invoices/receipts.
If you just purchased a plan and your account still shows nothing, this is usually because the new payment created a fresh Stripe customer that has not yet been linked to your app account. Please contact support so we can connect the payment and provision your plan — there is no need to pay again.
