Owners usually arrive asking which level they should buy. That is the wrong end of the question. Almost nobody purchases assurance because they want it — they purchase it because a document somewhere specifies it. Find the document first.
Where the requirement is written down
- Loan agreements. The covenant section names the level and the deadline, usually within 90 or 120 days of year-end. This is the most common trigger we see, and the language is frequently negotiable before signing and occasionally after.
- Bonding and surety programmes. Contractors typically find that their bonding capacity steps up with the level of assurance. Moving from review to audit is often what unlocks a larger single-job or aggregate limit.
- Investor and buyer diligence. Not always contractual, but a buyer discounting for uncertainty is charging you for the absence of an audit whether or not anyone says so.
- Regulatory, grant, and plan requirements. These are the least negotiable. An employee benefit plan crossing the participant threshold, a grant condition, or a licensing body sets a level and a deadline you meet or fail.
Ask your lender before you commission anything. We have seen owners buy an audit to satisfy a covenant that specified a review. The gap between the two is a substantial fee difference and several weeks of your team’s time, spent for nothing.
What each level costs you beyond the fee
An audit is not just more expensive — it is more intrusive. Confirmations go out to your bank, your customers, and your lenders. We will ask for documentation your team has to find. Plan for the internal hours, not only the invoice.
The cheapest way through any of the three is to have books that were closed properly all year. Assurance on records we already maintain moves faster than assurance on records assembled retroactively, because the reconciliations and schedules already exist in the form the engagement needs.
