Cards on File, the Safe Way
Keeping a customer's card on file is one of the handiest things a small business can do — and one of the easiest to do in a risky way. The safe way is simple: your processor stores the card in a secure vault and gives you a harmless stand-in (a token) to charge later, so you never write the real number down. Get the customer's permission in writing, set clear terms, and send a receipt every time. This guide walks through deposits, recurring charges, and the one habit that gets businesses in trouble.

Common Questions
1 Is it legal to keep a customer's card on file?
Yes — with the customer's permission and with the card stored securely by your processor. What you must never do is store the full card number yourself, on paper or in a spreadsheet. Get the okay in writing and let the vault hold the card.
2 How does a card on file work without storing the number?
It's called tokenization. Your processor keeps the card in a secure vault and hands you a random stand-in — a token — that only works inside your account. You charge the token; you never see the real 16 digits again.
3 Do I need the customer's permission in writing?
Yes. A signature, a checkbox, or a signed estimate stating the amount, the schedule, and how to cancel. Keep a copy — it's your best protection if a charge is ever disputed.
4 Can I use this for deposits on jobs?
Absolutely. Take the deposit, save the card on file with the customer's okay, then charge the balance to the saved card when the work is done — no chasing a check. Put the terms on the estimate they sign.
5 A customer emailed me their card number — now what?
Enter it, run the charge, and delete the email. Don't save or forward it — a card number in your inbox is a card you're storing. Next time, send a payment link so they type it themselves.
6 What happens when a saved card expires?
Many systems auto-update a reissued card. When a charge fails, ask the customer to update the card through a link or at the counter — never by email. A failed charge is routine, not a crisis.
Would You Rather I Just Help?
Setting up deposits and recurring charges is one of my favorite things to help with, because the safe way is easy once someone shows you once. I'll set up the authorization, the recurring schedule, and the receipts so you never touch a card number, with nothing to sell you. $99 flat for a visit, 30-day come-back-free.
Would you rather I just do this for you?
No shame in it — plenty of folks would rather hand it off, and that's what I'm here for. I'll come to your home, set it up right, and make sure it's working before I leave. Flat $99 per visit — no jargon, no upsell, and every visit is 30-day come-back-free.
Not a hardware job? I can often fix it remotely for $49 — a secure screen-share, up to 2 hours, that you watch the whole time and can end whenever (included free for $39/mo Support Plan members, and it counts toward the $99 if it turns out I need to come out).
