The average Nigerian statutory audit takes 38 working days from kick-off to signed opinion. The audits we deliver inside Claudenia's "audit-ready" client base take 14. The difference is not skill or staffing — it is the 30 days of preparation before the auditor walks in.
Below is the countdown we share with every client at the start of their last quarter. It works for finance teams of one as well as for those of fifty.
Day 30 to 21 — Reconcile everything that should reconcile
Bank reconciliations down to the last kobo for every account. Customer and supplier sub-ledgers tied to the general ledger. Inventory counts initiated, with cycle counts where physical counts are impractical. Fixed asset register agreed to the GL. If any one of these does not tie, fix it now while the records are fresh.
If you only do one thing from this article, do this: reconcile every balance-sheet account at least once. Auditors quote longer hours when they smell unreconciled balances.
Day 20 to 15 — Document significant transactions
For every transaction above your materiality threshold (typically 5% of profit before tax, or ₦5m, whichever is lower), assemble a one-page memo: economic rationale, accounting policy applied, supporting documents. Common candidates: asset disposals, foreign exchange revaluations, settlement of disputes, related-party transactions, share issuances.
Day 14 to 10 — Prepare your IFRS judgement file
IFRS demands judgements; auditors demand evidence of those judgements. Build a small folder with:
- Expected credit loss model and assumptions (IFRS 9)
- Revenue recognition pattern for each material contract (IFRS 15)
- Lease classification and IFRS 16 calculations for every operating lease over twelve months
- Impairment indicators reviewed for goodwill and right-of-use assets (IAS 36)
None of these need to be elaborate. They need to exist before the audit team arrives.
Day 9 to 5 — Internal review
Walk through your draft trial balance with someone who did not prepare it. Question every variance over 10% against last year. Have the explanations ready when the auditor opens the same question. Most of the back-and-forth in an audit happens here; preparation eliminates 60% of it.
Day 4 to 1 — Build the auditor's data room
Create a shared folder structured the way auditors think: balance sheet, P&L, payroll, tax, governance. Drop everything they will ask for: bank confirmations sent, board minutes, tax filings, contracts, related-party agreements, statutory registers. The smoother the data room, the more goodwill you bank for when surprises come up.
The two surprises that derail Nigerian audits
After 11 years of practice we see the same two issues take down 70% of late audits:
- Bank confirmation delays. Send your confirmation requests at least 14 days before the audit. Some Nigerian banks take three weeks.
- Stock count adjustments. Physical inventories almost never tie to book on the first count. Investigate the variance now — not in February.
What an audit-ready file looks like
The clients we describe as fully audit-ready typically have: a clean trial balance, a 4-tab variance analysis, supporting schedules for every line item above materiality, a complete IFRS judgement file, signed bank confirmations and an updated fixed-asset register with photos for additions above ₦5m.
That sounds like a lot. In practice, with a well-run cloud bookkeeping setup, it takes one finance officer eight working days to assemble.
