A declined payment is usually the client's card, not your setup. Here's how to sort it out.
What to check
Ask the client to try again. Most declines are a wrong number, an expired card, or insufficient funds — a retry with correct details often works.
Try a different card. Have them use another card or payment method.
Record another way. Paid you by cash or check instead? Open the invoice, tap Collect Payment, and record it so the invoice updates.
Note: Online card payments run through SityPay. If no card is going through at all, confirm SityPay is set up — see Set up SityPay to accept card payments.
