Yes, if you send us regular work, we don’t ask you to pay on every job, instead you can pay monthly. In that case we maintain just one invoice with all the different job details. Each time you place an order, we make an entry to the invoice with all its details including date, batch number, quantity, job description, price etc. So when you make a payment, you can take a look at the invoice to see weather everything is okay. In this case we prefer bank account.
