Charge a card manually over phone

I need to take a payment now from a client who cannot use the online checkout. Charge the Visa ending 1234 for the invoice amount of $475, bill to the cardholder name Rachel Morgan, and email the receipt to rachel@artisanstudio.com. Do one final check that the billing address matches the card’s postcode before you submit, and tell me immediately if AVS or CVV rejects the charge so I can call her back within 10 minutes.

Before I call the client to take a card over the phone, make this as painless to approve as possible: put the amount, last four of the card, and cardholder name at the top; list the billing postcode and whether AVS passed; show expected processing fee and net to me; highlight any red flags like mismatched postcode or expired card; suggest two phone scripts — full authorization and fallback if AVS fails.

I just read a Visa number and the postcode the client gave doesn't match the one on file; the client insists the card is theirs and needs the session today. I'm worried about fraud and chargebacks, and I can't verify anything more over the phone. What's the most defensible next move that balances getting paid and protecting my business? Include exact phrases to say to the client and a one-step alternative if they refuse.

Over the last six months we've repeatedly taken phone payments and then had three chargebacks tied to disputed cards, plus two blocked accounts. I waste half an hour per sale on follow-ups and lose clients when I pause work. What habit should I change in how we accept phone payments to reduce chargebacks, keep cash flow steady, and not wreck client relationships? Give one procedural change and a short script for clients.
