Bookkeeping for Small Business: A Routine That Holds Up

Small business bookkeeping is the routine of recording every dollar that comes in and goes out, matching it to your bank statements and keeping the paperwork that proves it. Done weekly, it takes a few hours. Saved up for tax time, it becomes a rescue job.

Our bookkeeping service works inside each client’s own QuickBooks Online or Xero file. The routine below is the one we work to.

Set up the foundations once

• Separate business and personal money. A dedicated business bank account and card make every later step easier. The SBA explains how to open a business bank account.
• Choose an accounting method. Cash basis records income and expenses when money moves. Accrual records them when earned or incurred. IRS Publication 538 covers accounting periods and methods; confirm the choice with your accountant.
• Pick cloud accounting software and connect your bank feeds.
• Keep a simple chart of accounts. Too many categories cause more errors than too few.
• Decide where documents live. One folder structure for receipts, bills, invoices and statements.

The weekly routine

1. Categorize new bank and card transactions.
2. Attach or file the receipt or bill for each expense.
3. Enter supplier bills and their due dates.
4. Send invoices for work completed.
5. Record customer payments against the right invoices.
6. Follow up on overdue invoices.

The monthly routine

1. Reconcile every bank, card and loan account to its statement.
2. Review unpaid bills and unpaid invoices.
3. Record payroll and any taxes withheld.
4. Check for uncategorized or duplicated transactions.
5. Review the profit and loss and balance sheet for anything that looks wrong.
6. Save the reports and statements for the month.

Reconciliation is the step that catches errors. If the books do not match the bank, something is missing, doubled or miscoded. For a fuller version, see our outsourced accounting page, which covers the month end close.

Quarterly and at year end

• Set aside or pay estimated taxes on the schedule your accountant gives you.
• Review the year to date results with your accountant.
• At year end, gather statements, loan documents, asset purchases and payroll summaries for your tax preparer.
• Issue any required year end forms to contractors and employees.

Which records to keep, and for how long

The IRS lists the records a business should keep: gross receipts, purchases, expenses, travel and asset records, and employment tax records. It also explains how long to keep them. The period depends on the document and the situation, so check the guidance or ask your accountant before discarding anything.

Common mistakes

• Mixing personal and business spending. It makes every report unreliable.
• Skipping reconciliation. Errors compound each month they go unnoticed.
• Leaving receipts until later. Later, nobody remembers what the purchase was for.
• Miscategorizing owner draws and loan payments as expenses.
• Not following up on invoices. Unpaid invoices are a cash problem, not a bookkeeping detail.
• Doing it all in the last week before the tax deadline.

Doing it yourself, hiring or outsourcing

• Do it yourself if you have few transactions and the discipline to do it weekly.
• Hire a part time bookkeeper if you want someone on site and have enough work to keep them busy.
• Outsource if the work is steady but not a full time job, or you want it done on a fixed schedule without managing an employee.

Whichever route you choose, keep ownership of the accounting file and the bank access, and keep approvals with you. Our outsourced bookkeeping service works that way: your file, your permissions, your approval steps.

When to bring in an accountant

A bookkeeper keeps the records. An accountant or CPA handles tax returns, tax planning and advice. Our guide to bookkeeping vs accounting explains where the line sits.

Frequently asked questions

How often should a small business do its bookkeeping?

Weekly for recording and invoicing, monthly for reconciliation and review. Leaving it longer makes errors harder to find.

What is the difference between cash and accrual bookkeeping?

Cash basis records income and expenses when money changes hands. Accrual basis records them when they are earned or incurred. Your accountant can confirm which applies to you.

What records does a small business need to keep?

Receipts, invoices, bank and card statements, payroll records and documents supporting assets and loans. The IRS publishes guidance on which records to keep and for how long.

When should a small business outsource bookkeeping?

When the owner is doing it late at night, when the books are more than a month behind, or when the work is steady but not enough for a full time hire.
