How often should I reconcile my bank accounts?

Monthly, without exception — ideally within the first 10 days after the statement closes. Businesses with high transaction volume or active job costing often reconcile key accounts weekly. Anything less frequent and errors compound faster than you can find them.

Isn't the QuickBooks bank feed already reconciling my books?

No. The bank feed is a data-entry tool — it brings transactions in, but it doesn't verify that your books match the statement. Reconciliation is the separate step that proves the two records agree. A file can have a 'clean' feed and be thousands of dollars wrong.

What problems do reconciliations actually catch?

Duplicate expenses, missing deposits, miscategorized transfers, unauthorized or fraudulent charges, bank errors, uncashed checks, and income recorded twice by connected apps. On construction files, they're also what catch sales tax and job-costing gaps early.

What does it mean if my books haven't been reconciled in months?

Every report in the file is unreliable — the cash balance, the P&L, job profitability, all of it. The fix is a cleanup engagement that reconciles each account from the last known-good month forward, then sets a monthly close process so it never lapses again.

Which accounts should be reconciled besides my bank account?

Every account that has an outside record: credit cards, loans and lines of credit, merchant processors (Stripe, Square), payroll liability and clearing accounts, and vendor/subcontractor balances against their statements. Bank-only reconciliation leaves most of the balance sheet unverified.

How do I reconcile a loan in QuickBooks?

Match the loan account balance to the lender's statement or online payoff figure each month. Every payment should be split between principal (reducing the loan balance) and interest (expense) per the amortization schedule. If the balance in QuickBooks doesn't match the lender, the split is wrong somewhere.

Why do my payroll liability accounts keep growing?

Usually because payroll taxes were recorded as a liability but the payment was coded to an expense account, or a payment was never recorded at all. The liability account should return to roughly zero after each tax deposit. A growing balance means penalties may be accruing — reconcile it against your payroll provider's reports immediately.

Why reconciliations matter (and how to do them right)

A reconciliation is the process of matching every transaction in your books against an outside source of truth — a bank statement, credit card statement, loan statement, payroll report, or vendor statement. It's not busywork — it's the single control that proves your numbers are real. Skip it, and every report you look at (P&L, job profitability, cash balance, loan balances) is a guess.

Who this is for: Contractors, developers, and small business owners who want financial reports they can actually trust — especially before applying for financing, filing taxes, or making hiring decisions.

Step-by-step

1. Start with the bank statement, not your books
Reconciliation always works from the bank's record toward your books. Pull the official statement (PDF or bank feed) for the period. The bank's cleared transactions are the ground truth — your books are the version you're testing.
2. Match every cleared transaction
In QuickBooks Online, go to Bookkeeping › Reconcile and match deposits, checks, card charges, and transfers to the statement line by line. Anything in your books that isn't on the statement is either a timing difference (outstanding check, deposit in transit) or an error.
3. Investigate every difference — never force it
A difference of even a few dollars means something is off: a duplicate expense, a missing deposit, a transposed number. QuickBooks offers an 'Adjustment' button to force the reconciliation to zero — using it hides the problem and compounds it month after month.
4. Look for what ISN'T in your books
Reconciliation catches missing revenue as reliably as missing expenses. If a customer payment hit the bank but never got recorded, your books understate income — and your sales tax filings understate it too. That's a compliance problem, not just a bookkeeping one.
5. Reconcile credit cards and merchant processors
Credit cards get reconciled to the monthly statement exactly like a bank account — every charge, payment, and fee. Merchant processors (Stripe, Square, Buildertrend payments) get reconciled to their payout reports, because deposits hit the bank net of fees and refunds — the deposit alone never tells the full story.
6. Reconcile loan and line-of-credit balances
Match your loan accounts to the lender's statement: the balance in QuickBooks should equal the lender's payoff figure, and every payment should split correctly between principal and interest. Books that show the full payment as an expense overstate costs and understate the liability — a red flag for any lender reviewing your financials.
7. Reconcile payroll liability accounts
Payroll clearing and liability accounts (federal/state withholding, unemployment, L&I in Washington) should return to zero after each remittance. A growing balance means a tax payment was missed or double-recorded — and payroll tax penalties are among the most aggressive the IRS and state agencies assess.
8. Reconcile vendor and subcontractor balances
Compare your Accounts Payable aging to vendor statements, and your open subcontracts to what subs say you owe. This catches double-paid bills, missing credits, and retainage that was released but never recorded — all common on construction files with high vendor volume.
9. Lock the period after reconciliation
Once a month reconciles clean, close the books in QuickBooks (Settings › Advanced › Close the books) with a password. This stops anyone — including you — from quietly editing a reconciled period and unraveling the whole chain.

Pro tips

Reconcile by the 10th of the following month so errors are still fixable and memories are fresh.
Use bank rules to auto-categorize recurring transactions, but never let rules auto-ADD transactions without review.
Watch for duplicate income from connected apps (Buildertrend, payment processors) double-posting deposits — reconciliation is what catches it.
Keep the reconciliation report attached to each month's close file — lenders and the IRS both ask for it.
Compare your loan balance in QuickBooks to the lender's online payoff quote quarterly — it's the fastest sanity check that principal/interest splits are right.
Tie the payroll liability report in QuickBooks to your payroll provider's tax filings each quarter; the two must agree before you file.
Ask your top 5 vendors and subs for statements quarterly and match them against your AP aging — it takes 30 minutes and catches double payments.
If a reconciliation hasn't been done in months, do a cleanup engagement first; reconciling on top of a broken file just paperwork the mess.

Common pitfalls

Clicking 'Reconcile anyway' and letting QuickBooks plug the difference to an adjustment account.
Reconciling only the checking account while credit cards, loans, and payroll liabilities drift for months.
Booking the full loan payment as an expense instead of splitting principal and interest — profits get understated and the loan balance never ties out.
Ignoring payroll liability accounts until an IRS or state notice arrives — by then penalties have been accruing for months.
Never reconciling vendor balances, then paying the same subcontractor invoice twice.
Deleting or editing transactions in a reconciled period instead of correcting them in the current one.
Treating the bank feed as reconciliation — accepting feed transactions is data entry, not verification.
Discovering at tax time that the books never matched the bank, and paying cleanup rates on top of CPA fees.
