Month-end close checklist for startups: 12 steps, a 5-day calendar and the adjustments that matter

A startup's month-end close has 12 steps: confirm every bank and card feed synced, categorize every transaction, attach receipts, reconcile each account to its statement, match payment processor payouts, review receivables and payables, post payroll, post prepaid, deferred revenue and accrual entries, review the profit and loss, check the balance sheet, send the report and lock the month. Five business days is a good target.

The short version

The first five steps (feeds, categories, receipts, reconciliation, payouts) do most of the work, and every later step depends on them.
A month is closed when every account's difference to its statement is $0.00 and nothing is left uncategorized.
Most startup months need only three adjusting entries: prepaid expenses, deferred revenue and accrued expenses.
In Ledge's 2025 survey of 100 finance teams, only 18% closed in 1 to 3 business days and 50% took 6 or more.
Locking the month stops the numbers from moving, and reopening it should take a named person and a written reason.

A startup's month-end close is 12 steps, and the first five do most of the work

The table below is a working checklist for a startup with payroll, a payment processor such as Stripe and a few bank and card accounts. The day column is a target in business days after month end, not a rule.

Month-end close checklist for a startup, with what done means and a target day
Step	What to do	Done when	Day
1	Confirm every bank, card and payment feed synced through the last day of the month	Each account's last transaction is on the last day or after, with no reconnect warning	1
2	Categorize every transaction	Nothing is uncategorized and the review queue is empty	1 to 2
3	Attach receipts and contracts to large payments	Every payment over your threshold (for example $500) has its document	2
4	Reconcile each bank and credit card to its statement	The difference is $0.00 on every account	2
5	Match payment processor payouts to bank deposits	Every payout matches a deposit and the processor fees are booked	2
6	Review receivables: invoices sent, payments applied, anything unpaid past 60 days	The aging report is read and follow-ups are assigned	3
7	Review payables: bills received but not yet paid are recorded	The payables list equals the bills on hand	3
8	Post payroll	One entry per pay run, with totals equal to the payroll report	3
9	Post prepaid, deferred revenue, accrual and depreciation entries	Each schedule has posted this month's share	3 to 4
10	Review the profit and loss against last month	Every line that moved by more than 20% and $1,000 has a reason	4
11	Check the balance sheet	Cash equals the bank, no receivable or payable is negative, equity matches the cap table	4
12	Send the month-end report and lock the month	The report is sent and the period is locked	5

Three adjusting entries cover most startup months

Cash moves on one date and the work it pays for happens on others. Adjusting entries put each dollar in the month it belongs to. Three of them show up almost every month.

Worked example: prepaid, deferred revenue and accrued expenses

Prepaid: on December 1 the company pays $6,000 for a year of insurance. Debit Prepaid expenses $6,000, credit Cash $6,000. Each month: debit Insurance expense $500, credit Prepaid expenses $500.

Deferred revenue: on October 1 a customer pays $24,000 for a year of subscription. Debit Cash $24,000, credit Deferred revenue $24,000. Each month: debit Deferred revenue $2,000, credit Subscription revenue $2,000.

Accrued expense: a contractor does $3,000 of work in December and the invoice arrives in January. On December 31: debit Contractor expense $3,000, credit Accrued expenses $3,000. When paid in January: debit Accrued expenses, credit Cash.

Effect on December's profit: revenue of $2,000, insurance of $500 and contractor cost of $3,000 all land in December, though cash moved in other months.

A schedule that posts the same entry each month turns the first two into a setup task instead of a monthly one. The accrued expense is the one that needs a person to ask what work was done but not yet billed.

A five-business-day calendar fits a startup with a few accounts

Step 1: Day 1: check that every feed synced, then categorize everything. Answer the review questions on unfamiliar vendors.
Step 2: Day 2: attach missing receipts, reconcile each bank and card, and match payouts.
Step 3: Day 3: read the receivables and payables lists, post payroll, and post the schedules.
Step 4: Day 4: read the profit and loss and balance sheet against last month and write a sentence for every big move.
Step 5: Day 5: send the report, lock the month, and note anything to change in the process next month.

Reconciling cash is the step that stretches most. Ledge's survey found finance teams spend 20 to 50 hours a month on it, often across three to five systems. Live bank feeds remove most of those hours.

Check these six numbers before you lock

Cash on the balance sheet equals the bank balance on the last day, account by account.
The uncategorized and suspense accounts are at $0.
Accounts receivable has no negative customer balance, and payables has no negative vendor balance.
Payroll expense in the books equals the payroll report, including employer taxes.
Revenue equals what your invoices and payment processor show for the month.
Equity matches the cap table, and any SAFE or note is where your CPA wants it.

Locking the month stops the numbers from moving, and reopening leaves a record

Once a month is locked, nobody changes its transactions by accident. A change to a closed month should need an owner or controller and a written reason, so the report you sent your CPA or investors still matches the books. That matters because the next month, the tax return and the Delaware annual report all start from the closed figures.

Continuous close goes further: transactions are categorized and matched as they arrive, so the last-day work is a review and a lock. The guide to how long a close should take has the benchmarks.

Questions founders ask

What is a month-end close?

The set of steps that finishes one month's books: every transaction categorized, every bank and card account reconciled, adjusting entries posted and the numbers reviewed, ending with the month locked.

What are the steps of a month-end close?

Confirm feeds, categorize, attach receipts, reconcile accounts, match payouts, review receivables and payables, post payroll, post adjusting entries, review the profit and loss and balance sheet, send the report and lock the month.

How long should a month-end close take?

Five business days is a good target for a startup. In Ledge's 2025 survey of 100 finance teams, 18% closed in 1 to 3 business days, 32% in 4 to 5, and 50% took 6 or more.

Do I need to close my books every month as a startup?

It is the easiest way to keep the books right. Each month is reconciled while the transactions are fresh, your CPA gets a clean year, and your investor updates use numbers that stop changing.

What are adjusting entries?

Entries that move a payment or a charge into the month it belongs to. Common ones are prepaid expenses, deferred revenue, accrued expenses and depreciation.
