Help: Billing · 4 min read # Take online payments with Paystack How customers pay invoices online in AquaOps: the payment link, the processing fee choice, confirmation and what staff can and cannot do. By the AquaOps team *[Image: Water flowing from an inlet into a bright blue swimming pool]* Customers can pay an invoice online by card or bank transfer through Paystack. Availability of live online payments depends on your company’s setup; ask us. ## How a customer pays 1. You issue the invoice and send it (**Send** emails a PDF with a link to up to five addresses). 2. The customer opens the link, or signs in to the customer portal, and chooses **Pay online**. 3. They pay on the payment page. The payment is tied to that one invoice. 4. Paystack tells AquaOps the money arrived. Only then does the payment count, the invoice update and the receipt become available. ## The processing fee On each invoice or quote there is a switch for who pays the online processing fee. By default the setting follows your billing settings. If the customer pays, the fee appears as a **“Payment processing fee” row** beside the tax, so the total on the document is exactly what they pay. ## What staff can do ## Your online balance Money collected online is tracked in your company’s online balance. Withdrawals to a bank account need a verified account, your password and a second proof, and they are held for a short time for safety. Owners and people with the wallet permission see this under **Billing**.

No. An online payment becomes real only when Paystack confirms it. Staff can record cash, bank transfer, POS and cheque payments themselves. Who pays the processing fee? You choose on each invoice or quote. If the customer pays it, it is shown as its own line, so they are never charged something that is not on the document. ## Keep reading - [Create a quote and take a deposit](https://aquasops.com/help/create-a-quote-and-take-a-deposit) - [Set up roles and permissions for your team](https://aquasops.com/help/set-up-roles-and-permissions) ## Want to see it working on your own data?
