How to close your books faster at month-end: a practical guide for Nigerian finance teams

Most month-end closes in Nigeria run late because everything starts on the same day. Statements arrive, someone exports the cash book, the POS reports are on a branch manager's phone, and the PAYE deadline on the 10th is already close.

A faster close comes from three changes: reconcile daily, give every task a named owner and reviewer, and run the close to a calendar that already holds your statutory dates.

Reconcile daily, not monthly

Reconcile bank, POS and processor accounts every working day and month-end becomes a check of a few days' work, not thirty.

APQC benchmarks, reported by CFO.com in May 2026, put one bank reconciliation at about 4 hours at the median. Done monthly, that time lands in the first days of the close.

Daily work also catches problems while they are small: a missing POS settlement is found the next day, an unknown credit is queried while the customer remembers it, and bank charges are booked as they happen.

A month-end close calendar

"Day 0" is the last working day of the month. Adjust to your own reporting deadline.

The Nigerian statutory dates in your close

Statutory payments fall inside the calendar, not after it.

Two things catch teams out. The pension deadline counts working days from payday, so a late-month payroll pushes it into the next close. And when a deadline falls on a weekend or public holiday, plan to pay before it. Confirm the rules that apply to you with your tax adviser.

Owners, reviewers and evidence

A checklist without names is a wish list. Every task needs an owner, a reviewer who is not the owner, a due date and evidence, such as the signed reconciliation or the remittance receipt. The reviewer can start on Day +2 while the owner moves on, and the sign-off is what your auditor will ask for at year-end.

Balance sheet reconciliations and variance review

The accounts that slow a close are usually the ones nobody owns: clearing, suspense, payroll control, tax payables, prepayments, accruals and fixed assets. Each needs a schedule that ties to the trial balance, an owner and a reviewer. Then compare each balance with last month and budget, and explain every movement above your threshold. Example figures: with a ₦500,000 threshold, bank charges rising from ₦120,000 to ₦780,000 need an explanation before the accounts go out.

How Brillrec helps

Brillrec is the finance operations platform for Nigerian businesses, with three products: Reconciliation, Internal Control Automation and Financial Close Management. They share one record: when a reconciliation is signed off, its close task completes and its control shows as operating, with who did the work and when.

In Financial Close Management, on every plan:

• checklists and templates for month-end, tax and statutory remittances, payroll and year-end returns, with an owner, reviewer and due date on every task (10 active checklists on Close and Essential, unlimited on Close Professional, Professional and above), or import your own from Excel, CSV or Word, checking each task first;
• statutory dates for PAYE, VAT and WHT, with weekends and holidays handled, each marked "to confirm" until a manager confirms it;
• requests by secure link, My tasks and reminders; approvers are emailed when something waits for them, and each person chooses which emails they receive;
• follow-up tasks suggested from reconciliation findings, such as overcharged fees, to accept or dismiss;
• a one-page owner's month-end report: cash, money found, reconciliation status and tax due.

In Reconciliation, on Essential and above:

• if the cash book is ready but the statement isn't, save the reconciliation and finish it when the statement arrives;
• when both sides arrive by themselves (a connection, the API, SFTP or emailed statements), Brillrec starts each period's reconciliation, and if nothing is left open and the balances agree it signs it off, marked "Signed off automatically by Brillrec"; an admin can switch automatic sign-off off;
• reviewers can approve, send back with a note or sign off from a phone under "Waiting for me";
• the Reports page: a month-end close tracker by account and open items by age, with CSV downloads;
• cash counts, note by note, signed by the custodian and reviewed by someone else.

Sign-off runs preparer, then an optional approver, then reviewer. It can require a reviewer who is not the preparer, and segregation of duties is checked. Signed-off reconciliations are locked, open items carry forward, and reopening needs a reason and is logged.

On Essential and above:

• daily reconciliations, so month-end is a check, not a start;
• balance sheet reconciliations, with the trial balance from your connected accounting system or a file; the preparer classes each open item (supported, timing, adjustment due or exposure), accounts above a threshold need a dated action plan, and the exposure report lists what the business is at risk of;
• balance review, flagging accounts at ₦1,000,000 and 10% unless you change the limits;
• tax accounts and the WHT tracker;
• files attached to tasks, type-checked and encrypted (5 GB on Close and Essential, 10 GB on Close Professional and Professional, 50 GB on Business);
• the Close dashboard and analytics.

A person edits and saves every AI draft of a variance explanation. AI is optional: an admin can switch it off, it never signs off or approves, and every use is logged.

Clients have reported 70% less month-end close time and 50% less audit preparation time. Results depend on your records and how your team works; see client results.
