Hello, I usually charge 50% in advance and the remaining 50% after the work is completed. But I am not able to find the option to add a card on the file while generating an invoice for my one-time/new customer. Could you please tell me how can I do that? As if the card is on file I will be able to charge them automatically once the project is complete, if I have to send them the invoice again to make a payment that might cause some issues as not all the clients respond after the project is complete with their 50% payment.
