The Monthly Close for Ottawa Small Business: A Checklist That Prevents Year-End Panic

Most small business bookkeeping happens once a year, in a panic, from a box. The cost of that approach is not the accounting fee. It is the deductions nobody could substantiate, the tax bill that arrived as a surprise, and the four months of decisions made without knowing whether the business was profitable.

A monthly close fixes all three, and it takes most small businesses somewhere between one and three hours a month once the routine is established.

What a close actually is

Closing a month means bringing the books to a state where the numbers are complete, reconciled and not going to change. Once a month is closed, you stop touching it. Corrections go into the current month.

That last part is the discipline people skip, and it is what makes the whole thing work. Books that stay permanently open are books nobody can rely on, because any number might be revised.

The checklist

Work through these in order. The sequence matters: reconciliation before review, review before reporting.

1. Import and categorise every transaction

Every bank account, every credit card, every payment processor. Nothing left uncategorised and nothing sitting in a suspense or “ask my accountant” bucket at month end.

If a transaction genuinely cannot be identified, note what you know about it while you still have some chance of recalling it. In eleven months you will have none.

2. Reconcile every account to its statement

The closing balance in your books must equal the closing balance on the statement. Not approximately: exactly.

This is the single most valuable step in the list, because it is the only one that proves nothing is missing. Categorising transactions tells you what you recorded. Reconciling tells you whether you recorded everything.

An unreconciled difference is a message. Chase it.

3. Match receipts to expenses

The CRA’s position on keeping records is that a bank or credit card statement proves money moved, not what it was for. The receipt or invoice is the evidence.

Photograph receipts when you get them. Most accounting software will attach an image to the transaction, which means the documentation lives with the entry rather than in a drawer.

For anything unusual, add a one-line note about the business purpose. Written now it is a record. Written in two years it is a reconstruction: the distinction that decides outcomes in a CRA review.

4. Review accounts receivable

Which invoices are outstanding, and how old are they?

Thirty days is normal. Sixty is a conversation. Ninety is a decision. The value of reviewing this monthly is that it is still a conversation at sixty days and a write-off at a year.

5. Review accounts payable

What do you owe and when is it due? This is where cash flow surprises come from, and a monthly view gives you a runway.

6. Record the non-cash items

The entries that never appear in a bank feed and are therefore always forgotten:

• Depreciation on equipment and vehicles
• Prepaid expenses being used up; annual insurance recognised monthly rather than as one lump
• Accrued expenses incurred but not yet billed
• Owner transactions; money put in or taken out, which needs to be characterised properly rather than left ambiguous. See salary vs dividends

7. Reconcile the tax accounts

GST/HST collected and input tax credits should tie to what you will actually report on your return. A monthly check means the filing is a transcription rather than a reconstruction, and it makes clear whether the money you are holding is actually there. See GST/HST registration.

Payroll liabilities should tie to what you remitted. Remittance penalties are calculated on the full amount rather than the shortfall, so this is not a place to discover an error late: remittance due dates.

8. Update the mileage log

If you claim vehicle expenses, this is where the log gets brought current and the odometer noted. A month of driving is reconstructable. A year is not, see vehicle expense deductions.

9. Read the two statements

Profit and loss for the month, compared to the prior month and the same month last year. You are looking for the things that moved and asking why.

Balance sheet. Does anything look wrong? A negative bank balance, a suspense account with something in it, a customer balance that has not changed in six months: these are errors announcing themselves.

Ten minutes. This is the step that turns bookkeeping from compliance into management information.

10. Set aside the tax money

Move an estimate of corporate tax, GST/HST and payroll remittances into a separate account. Not conceptually: actually transfer it.

Money in the operating account gets spent. Every business that has ever been surprised by a tax bill had the money at some point.

11. Close the period

Lock it in your accounting software. Corrections after this point go into the current month.

How long this actually takes

For a business with a couple of hundred transactions a month and clean separation between business and personal spending, the whole list is comfortably under two hours.

For a business with commingled accounts and a shoebox, the first close might take a day. The second takes two hours. That first close is the price of never doing an annual excavation again.

The three things that make it fast

Separate business and personal banking completely. This is worth repeating because it halves the work on its own. Every commingled transaction is a decision to make and a decision to defend. A dedicated business account costs a few dollars a month.

Connect the bank feeds. Manual entry is slow and error-prone, and there is no reason for it. The setup options are covered in small business bookkeeping automation.

Set rules for recurring transactions. Your software can categorise the same supplier the same way every time. Ten minutes of rules removes most of the monthly categorisation work permanently.

What it prevents

Missed deductions. Expenses recorded monthly get claimed. Expenses reconstructed in April from memory do not.

Tax surprises. A quarterly estimate built on reconciled books is close to right. Corporate instalments and deadlines become manageable rather than alarming, see corporate tax deadlines and instalments.

Audit exposure. Documentation created contemporaneously is worth more than documentation created under pressure, and the difference frequently determines whether a claim survives.

Bad decisions. Hiring, pricing, and equipment purchases made against eleven-month-old numbers are made blind.

The annual accounting bill. Preparers charge by the hour, and a clean set of reconciled books costs materially less to work with than a box.

Getting started this month

Do not attempt to fix the whole year first. Close this month properly.

Then close next month. Once the routine is running, work backwards through the year in whatever spare time exists. The forward-looking discipline is what matters; the backlog is a separate, finite task.

If your books have not been reconciled in a while and you are not sure where to start, a single cleanup and a routine set up properly tends to pay for itself in the first year: usually in deductions that were being left on the table.
