Purchase and expense approvals

Map requests, checks, approvals and posting before configuring delegates, permissions and exceptions.

Separate submission, validation, approval and accounting posting. Define amount and category rules, conflicts of interest, delegates and returns before integrating systems. AI can assist preparation but should not replace approval decisions without explicit authorisation.

When to use this guide

For teams chasing email or spreadsheet approvals with missing attachments, unclear decisions or duplicate posting.

Write the policy before automating

Have the business owner confirm amounts, currencies, categories and approval levels, including whether multiple approvals require all or any approver. Preserve rule versions and effective dates, and agree how policy changes affect requests already in progress.

Keep amendments traceable

Changing amounts or attachments after approval may require renewed approval. Retain old and new values, editor and reason. Prevent applicants from changing decision history. Delegates should act through recorded authority rather than sharing a manager’s account.

Separate approved from posted

Show approved, pending posting, posted and failed-sync states separately. Reconcile using the same request identifier so retries cannot create another expense. The workflow should clarify ownership and exceptions rather than merely generating more reminders.

Illustrative scenario

Hypothetical workflow: an expense amount changed after manager approval returns for approval, followed by accounting checks and posting. An authorised delegate covers absence and each version remains traceable. The business must confirm the actual policy.

Frequently asked questions

Can AI approve requests directly?

Define authority and risk first; preparation assistance can precede any delegated approval.

Can we keep existing accounting software?

Check interfaces, fields and licences; retain controlled manual posting where needed.

Should overdue requests auto-approve?

Do not assume that. Escalation, reminders and delegation follow the agreed policy.
