How to Set Up QuickBooks Online When You First Start a Business

4. Build a chart of accounts you can actually read

The default chart of accounts is a starting point, not a system. Two mistakes cause most of the mess we clean up:

Too many accounts. A new business does not need 90 expense accounts. Aim for 25 to 40. If a category will not change a decision, it belongs inside a broader account, not on its own line.

Cost of goods sold used incorrectly. COGS is for direct costs of delivering the work — materials, subcontractors, direct labor, merchant fees on product sales. Rent, software, and insurance are operating expenses. Getting this line wrong is what makes gross margin meaningless; see how to calculate profit margin for what the numbers should look like.

Add the accounts your tax preparer needs (meals separate from travel, owner draws separate from payroll) and delete or merge the ones you will never use.

5. Connect bank feeds and set the opening balances correctly

Connect every business bank account, credit card, and payment processor (Stripe, Square, PayPal) to the bank feed. Then handle the start date deliberately:

• If the business is brand new, your opening balance is the owner's contribution — record it to Owner's Equity, not income.
• If the business has been running for months, pick a clean start date, enter the bank balance and the outstanding items as of that date, and pull historical transactions in from there.

Reconcile the first month before you do anything else. If month one does not reconcile to the penny, every month after inherits the error. If you are already several months behind, that is a catch-up bookkeeping project, not a setup project.

6. Use bank rules — carefully

Bank rules are the biggest time saver in QBO and the fastest way to create wrong books. Create rules only for vendors that are always the same category (utilities, software subscriptions, insurance). Do not auto-categorize big-box stores, Amazon, or anything that could be either materials or office supplies, and leave "auto-add" off until you have watched a rule behave correctly for a month.

7. Set up customers, items, and invoicing the way you sell

Create products and services that mirror how you actually price — by package, by hour, by job phase — so revenue reports match your pricing conversations. Turn on QuickBooks Payments only if faster collection is worth the processing fee, and record the fee as an expense so revenue stays gross. If you invoice progressively or hold retainage, use estimates and progress invoicing from the start; retrofitting that is painful.

8. Payroll and contractors

If you have employees, add payroll before the first pay run and let it post to QBO automatically — manual journal entries for payroll are a top-three source of errors we find. If you pay contractors, mark them as 1099-eligible in the vendor record and collect the W-9 before the first payment. Chasing W-9s in January is a self-inflicted wound.

9. Decide who does the work every month

QBO does not do bookkeeping; it records it. Whoever owns the monthly close should reconcile every account, review the P&L and balance sheet for anything odd, clear uncategorized transactions, confirm sales tax and payroll liabilities, then set the closing date password.

The five setup mistakes we clean up most often

1. Personal and business spending in the same account.
2. Everything dumped into "Uncategorized Expense" and never revisited.
3. Owner draws recorded as payroll or as an expense.
4. Bank feeds connected but never reconciled, so the books look complete and are not.
5. Starting on Simple Start, then needing job or project profitability a year in.

Your first-week checklist

• Business bank account and card open, personal spending out.
• Subscription tier chosen for the reporting you will need in year two.
• Fiscal year, accounting method, sales tax, and invoice terms set.
• Chart of accounts trimmed, with COGS defined correctly.
• All accounts connected and month one reconciled.
• W-9s collected, payroll connected if applicable.
• A named owner and a date for the monthly close.
