Monthly Close Checklist for Small Business (The 15-Minute Version)

#Why monthly close matters

The choice every small-business owner faces:

Option A: Close the books each month. 15-30 min/month × 12 = 3-6 hours/year of work.

Option B: Skip monthly close. Try to reconstruct everything at year-end. 8-40 hours of cleanup compressed into March, plus accountant fees for the reconstruction work.

The math is obvious but most owners don’t do monthly close. Reasons (in order of frequency):

1. Don’t know what monthly close means operationally
2. Don’t have systems set up to make close easy
3. Aren’t disciplined about doing it regularly
4. Think they need a bookkeeper to close (you don’t, for most small businesses)

This article fixes the first two.

#The 7-step checklist

The full monthly close, ranked by importance:

#Step 1: Bank feed sync + reconciliation (5-10 min)

For each business bank account + credit card + payment processor (Relay, Bluevine, Stripe, PayPal):

• Verify bank feed is connected and up to date through end of month
• In your bookkeeping platform (Kick, QuickBooks), open the reconciliation
• Match ending balance per bank statement to ending balance in books
• Investigate any unreconciled transactions (typically: pending charges that hadn’t cleared, or duplicates)
• Mark reconciliation complete

If bank feeds are clean (no missing transactions, no duplicates), this step is fast. If they’re not, this is where time goes — investigating discrepancies.

#Step 2: Categorize all transactions (5-15 min depending on volume)

For each transaction not auto-categorized:

• Identify what it is (vendor, payment, transfer)
• Apply the correct chart-of-account category
• Add memo notes if business purpose isn’t obvious from vendor name

For a business with ~100 transactions/month and AI auto-categorization (Kick), ~85-90% are auto-categorized. The remaining 10-15% need manual review.

Tip: review weekly instead of monthly. 25 transactions/week is faster + more accurate than 100 transactions/month because business context is fresh.

#Step 3: Owner draws + distributions (1-2 min)

For S-corp owners: record distributions taken during the month (separate from W-2 wages, which Gusto handles).

For sole props / single-member LLCs: record owner draws.

For partnerships / multi-member LLCs: record each partner’s draws + ensure capital account tracking is accurate.

#Step 4: Accruals + adjustments (2-5 min if applicable)

If you use accrual basis accounting, record:

• Accounts Receivable accrual (revenue earned but not yet collected)
• Accounts Payable accrual (expenses incurred but not yet paid)
• Prepaid expenses amortization
• Loan interest accrual
• Depreciation (annual or monthly, depending on policy)

Cash-basis taxpayers skip this step. Most small businesses are cash basis.

#Step 5: Review P&L for anomalies (2-3 min)

Run the month’s P&L. Quick sanity check:

• Revenue: roughly in line with expectations?
• Major expense categories: any unusually high or low?
• Net income / loss: explanation makes sense?

Anomalies trigger investigation. Often you’ll catch a misclassified transaction or a missed entry this way.

#Step 6: Review Balance Sheet (2-3 min)

Quick sanity check:

• Cash balance ties to actual bank balance
• Accounts Receivable matches outstanding invoices
• Accounts Payable matches outstanding bills
• Loan balances match lender statements (verify quarterly)
• Owner equity moves match draws / contributions

#Step 7: Lock the period (1 min)

In your bookkeeping platform:

• Lock the closed month (prevents accidental changes to closed periods)
• Note the close date + who closed (audit trail)

For Kick: there’s a “close period” function. For QuickBooks: same — “close period” with optional password.

#What I do differently from a bookkeeper

The 7 steps above are the same steps a professional bookkeeper would run on your books. The difference:

• Pro bookkeeper handles 5-20+ businesses, may take 60-90 min per business per month, but you’re not paying for your own time
• You running close for one business takes 15-30 min once you have systems set up

For most small businesses earning under ~$500K/yr, owner-led close is fine + saves $300-600/month vs. professional bookkeeping. Above that revenue level, the math typically flips in favor of pro bookkeeping.

#Tools that make this faster

The 15-minute timeline depends on having the right tools:

Banking: Relay or Bluevine (auto-categorization to Kick/QBO, clean feeds) Bookkeeping: Kick or QuickBooks Online (built-in AI auto-categorization) Receipt capture: Ramp or business credit card with auto-receipt Mileage: MileIQ or Everlance (auto-detected business miles) Document management: Basecamp portal or Google Drive folder structure

Without these tools, monthly close takes 1-3 hours instead of 15-30 minutes. The tools are worth the cost — $30-50/month for the bookkeeping platform + $40-80/month for the receipt-capture + $0 for the banking (most modern business banks are free).

#What goes wrong without monthly close

The most-common patterns we see at intake on clients who’ve gone 6+ months without close:

Missing transactions: bank feed lost connection somewhere, 3 weeks of transactions never imported. Without monthly review, this goes unnoticed for months. By cleanup time, sometimes the data is unrecoverable.

Misclassified transactions: a one-time tool subscription accidentally categorized as “marketing” when it’s really “software.” Auto-categorization gets things wrong; without review, the misclassification persists.

Duplicate entries: same transaction imported from two sources (bank feed + manual entry). Without reconciliation, the duplicate stays. Inflates expenses, understates income.

Loan balance drift: principal payments not properly recorded as balance-sheet reductions. Loan balance in the books doesn’t match the lender’s actual balance.

Owner-personal mixing: personal expenses paid from business account, not flagged. Personal grocery runs end up in “office supplies.” Audit risk + bad data for decision-making.

Cumulative impact: by year-end, none of the major financial reports tell the truth. Tax return is built on bad data. Decisions based on monthly P&L review are wrong.

#The discipline pattern

For owners building the monthly close habit:

Pick a recurring day: same day each month (e.g., 5th of the month for closing the prior month). Calendar it.

Set a recurring reminder: don’t rely on memory.

Start with 5 minutes: just do step 1 (bank reconciliation). Add other steps as the habit builds.

Don’t perfectionize: monthly close doesn’t have to be PERFECT, just consistent. 90% accuracy maintained monthly beats 100% accuracy reconstructed at year-end.

Make it shorter over time: as your business + processes mature, close gets faster. Aim for 15 min as the steady state.

#When to engage a bookkeeper

Most small businesses can DIY monthly close. Engage a professional when:

• Revenue exceeds ~$500K/year (close gets more complex)
• Multiple entities or multi-state operations
• Industry-specific complexity (construction job costing, agency revenue recognition, restaurant tip pooling, etc.)
• You hate doing it and skip it
• Your time is worth more than the bookkeeper’s fee

At ETS, we offer two paths: Kick self-serve at $75/hr for owners who want support but not full delegation, OR ETS-as-bookkeeper from $300/mo for owners who want full delegation.

#Common questions

What’s the difference between monthly close and tax-return prep? Monthly close gets the books to a defensible state. Tax-return prep reads the books + applies tax law to produce a return. Monthly close is the foundation; tax return is the output.

Can I skip months and catch up at year-end? Yes, but it’ll take 3-10× the time. And the further behind you get, the harder it is to remember context for ambiguous transactions.

What if I’m cash-basis — do I still need monthly close? Yes. Cash-basis bookkeeping is simpler (no accrual entries needed) but the bank reconciliation + categorization steps still apply.

Do I need to do monthly close before tax-return season? Yes. Returns built on un-closed books are tax returns built on guesses. We require monthly close for the prior year before we’ll prep your return.

How do I know if my close is “right”? At minimum: bank balances tie to actual statements, P&L runs cleanly with no “uncategorized” or “ask my accountant” entries, Balance Sheet balances (assets = liabilities + equity).

What about year-end vs. monthly? Monthly close is operational ongoing. Year-end close adds: 1099 prep + filing, equity rollover, asset depreciation finalization, year-end inventory count (if applicable), final accruals. Year-end close typically takes an extra 1-2 hours on top of the standard monthly close.
