We could not find a verified public median for how long an SME takes to close its books each month, so we do not quote one. Published figures come from surveys of larger finance teams and do not describe a 20-person company with one bookkeeper. The useful benchmark is your own: working days from the last day of the month to signed-off accounts, tracked for six months, with the days broken down by step. The steps that lose time are almost always the same four, and each can be shortened without changing your accounting software.
What does "monthly close time" measure?
Close time is the number of working days between the last day of the month and the day a named person signs the month's accounts as final. Pick that definition and keep it. Teams that change the definition each quarter cannot see whether they improved.
Count working days, not calendar days. A close that finishes on the 9th looks slow until you notice that the month ended on a Thursday and the 1st and 2nd were a weekend.
Record three timestamps every month:
- Month end cut-off. The last day of the period.
- Books complete. Every bank line matched, every bill and invoice posted, every accrual entered.
- Sign-off. A named person reviews and marks the month final.
The gap between 1 and 2 is the close. The gap between 2 and 3 is the review. Separate them. A fast close with a week of review queue is not a fast close.
Why is there no reliable SME benchmark?
Three reasons.
- Survey samples skew large. Close surveys usually draw from finance teams of dozens of people on enterprise ERPs. An SME with one person doing everything faces different constraints.
- Definitions differ. Some surveys count to a preliminary close, others to board-ready packs. A "five-day close" in one survey is a seven-day close in another.
- Scope differs. A trading company with inventory and multi-currency bills has more to reconcile than a services firm with 40 invoices a month.
Our view: a number from another company tells you little. A trend in your own number tells you a lot. If your close fell from 11 working days to 7 over a quarter, something worked. If it rose, something broke. You can act on either.
Where do the days actually go?
When we review an SME's close, the time sits in four places. Fact: this is a pattern from our reviews of client stacks, not a statistical result.
| Step | Typical cause of delay | What shortens it | |---|---|---| | Waiting for documents | Bills and receipts arrive late, by email, WhatsApp or paper | Collect from a single inbox; chase on a schedule | | Bank reconciliation | Matching by eye; unclear references | Rules-based matching with a person approving the rest | | Accruals and adjustments | Held in someone's head or a side spreadsheet | A standing checklist with last month's entries pre-filled | | Review | One reviewer, no fixed slot | A booked review slot and a short exceptions list |
The first row is usually the biggest and the least technical. A bookkeeper cannot post a supplier bill that has not arrived. The fix is upstream of the accounting software: where do bills land, and who chases the missing ones?
How do you measure close time without new software?
Use a sheet with one row per month and these columns:
- month;
- cut-off date;
- date books complete;
- date signed off;
- working days to complete;
- working days to sign-off;
- number of documents received after cut-off;
- number of journal adjustments after first review.
The last two columns tell you why. Late documents point to collection. Adjustments after review point to errors upstream of the reviewer.
After three months you have a baseline. After six you have a trend. Do not set a target before the baseline, because you will pick a number from a blog post.
Which statutory dates sit behind the close?
The close is not the deadline. It feeds the deadlines. A GST-registered business must file its return and pay one month after the end of its accounting period/filing-gst/due-dates-and-requests-for-extension), so a quarterly filer with an October to December period has until 31 January. If the quarter's last month closes on working day 12, you have about a week left for the return. A close that slips by three days reduces that margin by almost half.
Corporate tax follows the same logic. Companies file Estimated Chargeable Income within 3 months of the financial year end-filing), unless revenue is $5 million or below and ECI is nil. The year-end close drives that date.
So measure two things: the monthly close, and the margin between your year-end close and the ECI date.
What would a faster close look like for a 15-person company?
A concrete example, with illustrative numbers, not a measured result. A company closes in 10 working days. The breakdown:
- 4 days waiting for bills;
- 2 days on bank reconciliation;
- 1 day on accruals;
- 3 days in a review queue.
Collecting bills into one mailbox and chasing missing ones on working days 1, 3 and 5 attacks the first 4 days. A booked half-day review slot attacks the last 3. Neither needs a new ERP. After both, a 6 or 7 day close is plausible. Reconciliation and accruals come last, because they are the smallest.
The order matters. Teams buy reconciliation software first because it is the visible step. It is rarely the biggest.
How often should you review the number?
Review it once a quarter, not once a month. A single month moves for reasons that are not process: a holiday week, a staff absence, an audit request. Three months show direction.
At each quarterly review, ask three questions:
- Which step grew the most in working days?
- Which late documents came from the same five suppliers or customers?
- Which adjustments after review repeated from the previous quarter?
Repeated adjustments are the cheapest wins. If the same accrual is corrected every month, make it a standing entry. If the same supplier always sends late, change how you collect from that supplier. Write the change down, then watch the next quarter's number.
Keep the log. A close-time sheet with six quarters of notes is worth more than any external median, because it records what you changed and what happened.
Where KYN fits
KYN's own books run on the pattern above. Bills arrive from Gmail into a ledger, receivables are chased at 3, 14 and 30 days, and payroll follows 2026 CPF rules. For a manufacturer, we built a ledger of 3,309 reconciled rows with zero duplicates, and a 06:30 morning report to each department on WhatsApp at about S$0.05 per report.
If close time is your problem, the first 14 days are a review: we inventory your stack and interview the team to find which of the four steps costs the days. A full build ships in under 90 days. Everything runs in a cloud account in your name. See finance systems and our article on automating bank reconciliation in Singapore.
Frequently asked questions
What is a good monthly close time for a small business?
There is no verified public figure for SMEs, so we do not give one. Track working days from month end to sign-off for six months and aim to reduce your own number. A falling trend matters more than any outside target.
Should I measure close to books complete or to sign-off?
Both. Books complete shows how long the bookkeeping takes. Sign-off shows how long the accounts wait for review. Many teams find the review queue is a third of the total.
Does a faster close help with GST filing?
Yes. GST returns are due one month after the accounting period ends, so every working day saved in the close adds to the margin before the deadline.
