How to Write a Prepaid Expense Policy for Your Finance Team

Without a clear policy, different people on the same finance team will treat identical transactions differently. One person expenses a twelve-month software licence immediately. Another sets it up as a prepayment and amortises it. Both believe they are correct. A prepaid expense policy removes that ambiguity.

What Is a Prepaid Expense Policy?

A prepaid expense policy is a written set of rules governing when a payment should be deferred as a prepaid asset rather than expensed immediately. It defines the qualifying criteria, the minimum amount threshold, the amortization methods to use for different types of payments, and the approval and documentation requirements.

Capitalisation Threshold

The most important decision in any prepaid policy is the minimum threshold. Below this amount, payments are expensed immediately regardless of the coverage period. This avoids creating schedules for trivial amounts.

Most small-to-mid-sized businesses set this threshold between £500 and £2,000. The right number depends on your scale — it should be low enough to catch material items but high enough that you are not creating amortization schedules for every £50 subscription.

Qualifying Criteria

• Payment must be made before the benefit is received
• The coverage period must extend beyond the current accounting period
• The amount must exceed the capitalisation threshold
• The item must relate to a specific future period or service
• Insurance, rent in advance, software licences, and maintenance contracts typically qualify

Amortization Method by Type

Rather than deciding the amortization method case by case, the policy should specify the default method for common categories.

• Insurance premiums: straight-line over the coverage period
• Software licences: straight-line over the licence term
• Rent in advance: straight-line over the period paid
• Maintenance contracts: straight-line, or custom schedule if usage is seasonal
• Retainer fees: straight-line, or expensed when services are delivered

Documentation Requirements

Every prepayment should be supported by the original invoice or contract showing the coverage period, and a record of how the amortization has been calculated. Any mid-period adjustment — refund, termination, amount correction — should be documented with the reason.

Review and Governance

The policy should specify who is responsible for reviewing open prepayments each month, who can approve new prepayments above a certain threshold, and how often the policy itself is reviewed. An annual review is usually sufficient unless the business changes significantly.
