You're caught between wanting financial credibility and keeping costs reasonable. The choice between agreed-upon procedures (AUP) and a full audit determines both your budget and what stakeholders will actually trust about your numbers.
What's the Real Difference?
A full audit is a deep examination. An independent auditor tests controls, verifies transactions, and issues an opinion on whether your financial statements are presented fairly in accordance with generally accepted accounting principles (GAAP). Banks, investors, and regulatory bodies recognize this as the gold standard.
Agreed-upon procedures are more limited. You and the auditor decide in advance what specific tasks need doing—maybe reconciling bank accounts, testing revenue controls, or verifying inventory counts. The auditor performs only those procedures and reports findings without offering an opinion. Think of it as surgical spot-checks instead of a full physical.
Cost Considerations
This is often the deciding factor. A full audit typically costs $5,000 to $50,000+ annually depending on complexity, company size, and transaction volume. A small nonprofit or startup might spend $3,000–$8,000; a mid-market manufacturing firm could face $15,000–$40,000.
Agreed-upon procedures run narrower. You're paying only for specific work, so costs often fall between $2,000 and $15,000. If you need just three or four targeted procedures, expect the lower end. If you want procedures across multiple functions, costs climb.
Timeline and Disruption
Full audits demand more time. Your finance team prepares schedules, answers questions, and accommodates site visits. A typical audit takes 4–12 weeks from fieldwork start to report issuance, depending on size and complexity.
Agreed-upon procedures compress the timeline. Because scope is narrow, fieldwork might take 1–3 weeks. Reporting is faster too—sometimes 1–2 weeks after fieldwork closes. This matters if you need results before a lending decision or shareholder meeting.
When to Choose Each
Choose a full audit if:
- Lenders or investors require it (most banks do for loans over $250,000)
- You're seeking external capital or going through M&A
- Regulatory bodies mandate it (nonprofits receiving federal funding, certain industries)
- You need an auditor's opinion to establish credibility with major customers or partners
- Your financial statements will be widely distributed
Choose agreed-upon procedures if:
- You need internal controls tested in one or two specific areas
- Lenders accept AUP instead of a full audit (common for smaller credit lines)
- You want to verify one department's processes before rolling out company-wide changes
- You're investigating a suspected internal control weakness
- You need assurance on specific transactions or account balances without full-scope coverage
What Auditors Look For When Scoping
When you meet with an audit firm, they'll ask:
- Who's requesting this? (Their requirements shape scope)
- What specific concerns exist? (Revenue recognition issues, cash controls, payroll accuracy)
- Which accounts or processes matter most?
- What's your timeline and budget?
Be direct about these answers. A firm comparing AUP proposals on Mercoly will explain how each scope addresses your actual risks, not theoretical ones.
The Credibility Question
Here's what stakeholders actually accept:
- A full audit opinion carries maximum weight with banks, investors, and regulators
- Agreed-upon procedures work for smaller credit facilities, internal stakeholders, and specific operational decisions
- A bank may accept AUP if you're borrowing under $500,000 and have clean historical financials
- Government contracts often require full audits; AUP rarely suffices
If you're uncertain whether stakeholders will accept AUP, ask them directly before committing to that service.
Moving from AUP to Full Audit
Some companies start with AUP to test controls, then move to a full audit once controls strengthen. This phased approach can save money early while building confidence in your financial processes. It also gives auditors baseline data when they transition to a full scope.
Frequently Asked Questions
Q: Will my lender accept agreed-upon procedures instead of a full audit? Many will, especially for loans under $500,000 or if you have multiple years of clean financials. Ask your lender upfront what they'll accept; don't assume.
Q: How do I know if my specific control weakness needs AUP or a full audit? If the issue is isolated to one area (like revenue recognition in one division), AUP might suffice; if it's systemic or you need stakeholder confidence, a full audit is safer.
Q: Can I use the same firm for AUP now and a full audit later? Yes, and it's often beneficial since the auditor already understands your processes and risks.
