When a customer pays you (by bank transfer, cash, or cheque), you can mark the invoice as paid.
Via WhatsApp
Tell Gaffer: "Mark John's invoice as paid" or "John has paid". Gaffer updates the invoice status.
Via Stripe
If a customer pays via the Stripe payment link, the invoice is automatically marked as paid. No action needed.
Via Dashboard
You can also mark invoices as paid in Dashboard > Invoices.
