How long should you keep invoices?
There is no universal retention period. The right period depends on where you operate, your entity type, tax rules, contracts and whether a dispute is still possible.
Check the rules that apply to you
Start with the tax authority and company regulator for your jurisdiction. Record-keeping periods differ, and special rules may apply to payroll, property, grants, regulated work or cross-border transactions.
This guide is general organisation advice, not a statement of the period required in your country.
Keep the evidence with the invoice
An invoice is more useful when it remains linked to the quote, contract, purchase order, delivery evidence, credit notes and payment record. Together they explain what happened if a customer, accountant or authority asks later.
Use a consistent archive
Store readable copies by financial year with stable file names and backups. Make sure records remain accessible after changing accounting software, banks or staff.
Do not delete around an open issue
Pause routine deletion when an audit, chargeback, warranty claim, unpaid debt or legal dispute is active. When the applicable period has passed, dispose of records securely rather than leaving customer information in forgotten folders.
