Payment Data Retention: Keeping Useful Records Without Excess Data

How merchants can decide which payment records to keep, for how long and where, so they meet obligations and support needs without storing unnecessary personal data.
The short answer
Keep the payment records you need for accounting, tax, disputes and support, for as long as your obligations require, and avoid storing data you do not need, such as full card numbers or copies of identity documents without a clear reason. Write a simple retention schedule, store records securely with limited access, and delete or anonymise data when its period ends. This is general guidance; check the rules that apply to your business.
What you usually need
- Order and invoice records.
- Payment transaction references, amounts, dates and status.
- Refund and dispute records.
- Settlement reports and reconciliations.
- Receipts sent to customers.
What you usually should not store
- Full card numbers or security codes.
- Wallet PINs, passwords or one-time codes (never collect these at all).
- Identity document images unless required and handled under a clear policy.
- Unnecessary personal details in free-text notes.
Building a retention schedule
For each record type, write:
- Purpose: why you keep it.
- Period: how long, based on accounting, tax, legal or provider requirements.
- Location: which system stores it.
- Access: who can see it.
- End action: delete, anonymise or archive.
Example schedule (illustrative)
- Transaction records: purpose: Accounting, disputes; period: As required by your accounting rules; end action: Archive then delete
- Support chat logs: purpose: Customer service; period: Shorter period you define; end action: Delete
- Marketing consent: purpose: Proof of consent; period: While active plus a defined period; end action: Delete
Fill in periods based on professional advice for your situation.
Where data hides
Payment details often end up in spreadsheets, email attachments, chat apps and screenshots. Include these in your schedule and clean them up regularly.
Security
Restrict access by role, use encryption where available, and keep backups protected. See payment security best practices.
Customer requests
If customers ask what data you hold or ask for deletion, have a process to respond, balancing their request with records you must keep.
Running a cleanup
Once or twice a year, run a cleanup: check shared drives, old spreadsheets, chat exports and email folders for payment data that has passed its retention period or should never have been stored. Delete or anonymise it, and note what was removed and why. Repeated findings in the same place usually mean a process needs to change, for example customers sending screenshots that staff save to personal devices.
Supplier and provider data
Your provider and other tools also store payment data. Know what they keep and how to export or request deletion if you change providers.
Frequently asked questions
Can I just keep everything forever?
Keeping more data than needed increases risk and may conflict with data protection expectations.
