Click Pay now on any open invoice to charge your default card without
leaving the app. A confirmation dialog shows the card that will be used and the
exact amount.
If you have more than one card on file, click Use a different card in the
dialog to pick another one before confirming.
If the charge is declined, the decline reason appears inline in the dialog so
you can switch cards and retry — your session stays put.
If you don’t have a card on file yet, the dialog links to Payment methods
so you can add one and try again.
On a successful charge, the row’s status flips to Paid automatically and
your account state catches up (for example, a past-due account returns to
active).
If you haven’t been charged yet — or your account doesn’t have a Stripe customer
record yet — the page shows “No invoices yet — they’ll appear here after your
first charge.” This is expected for trial-only accounts and brand-new
sign-ups; no action is needed.
