When you first set up your bookkeeping system, one of the most important decisions you'll make is something most business owners don't even realize they're deciding: which accounting method to use. Cash or accrual. Choose wrong and your financial reports may not reflect what you think they do — and it can be a painful process to switch later.
Here's a clear explanation of both, and how to know which one your business should be using.
Cash Basis Accounting: Simple and Immediate
With cash basis accounting, you record income when the money actually hits your bank account, and you record expenses when you actually pay them. Nothing gets recorded until cash physically changes hands.
If you invoice a client on December 20th but they pay on January 10th, that income is recorded in January — not December.
- Best for: Freelancers, sole proprietors, service businesses with simple cash flows
- Advantage: Simple to maintain, easy to understand, matches your bank statement
- Disadvantage: Can give a misleading picture of profitability in any given period
Accrual Basis Accounting: More Accurate, More Complex
With accrual accounting, you record income when it's earned (even if you haven't been paid yet) and expenses when they're incurred (even if you haven't paid the bill yet). This gives a more accurate picture of your true financial position.
That same client invoice from December 20th? It's recorded as December income — which is when you earned it.
- Best for: Businesses with inventory, significant accounts receivable, or revenues over $25M (required by IRS)
- Advantage: Accurate picture of financial health; better for financial planning
- Disadvantage: More complex; can show profit before you've actually been paid
Which Does the IRS Require?
Most small businesses can use either method. However, if your business has inventory and average annual gross receipts over $25 million, the IRS generally requires accrual. When in doubt, check with your CPA.
Can You Switch Methods?
Yes, but it requires IRS approval and specific timing. Switching mid-year or without proper guidance can create a mess in your books. It's much better to set it up correctly from the start.
The Real Talk
I see this confusion cause real problems when a business owner thinks they're more profitable than they are (cash basis hiding large upcoming expenses) or more cash-rich than they are (accrual showing income that hasn't been collected). Know your method. Know what your reports are actually telling you based on that method.
Not sure which method your business uses? Ask your bookkeeper. If they can't tell you in 30 seconds, that's a problem worth investigating.
