If you have ever opened QuickBooks and seen a setting that says "Cash" or "Accrual" and just picked one, you are not alone. Most small business owners do that.
The choice matters more than people think. It changes what your profit looks like, when you pay tax, and how useful your books are for decisions. In our experience, picking the wrong method is one of the most common reasons an owner cannot make sense of their own numbers.
Here is a plain-English breakdown.
Cash basis is the simple one. You record income when money hits your bank account and expenses when money leaves it.
Invoice a customer in March for ten thousand dollars and they pay you in May? The income shows up in May. Order materials in March but pay the bill in April? The expense shows up in April.
It mirrors your bank account. That is the appeal.
Accrual basis records income when you earn it and expenses when you incur them, no matter when the cash moves.
Same example: invoice a customer in March, accrual books that income in March, even if you do not get paid until May. Materials ordered in March get expensed in March, even if you pay the bill in April.
Accrual lines up income with the work that produced it. That is what most lenders, CPAs, and serious financial planning need.
Say a contractor finishes a job in December for twenty thousand dollars. The customer pays in January. The contractor paid five thousand in materials in December.
On cash basis, December shows a five thousand dollar loss. January shows twenty thousand of income. Very confusing numbers.
On accrual basis, December shows twenty thousand of income and five thousand of expense, for a fifteen thousand dollar profit. The numbers reflect the actual job.
Same business, same dollars. Very different picture.
For most small businesses, the IRS lets you pick either method. Cash basis is allowed for most businesses with average gross receipts under twenty-nine million dollars per year (the threshold gets adjusted, so check the current number).
There are exceptions. If you carry inventory, the IRS may require accrual for that portion of your business. C corporations and partnerships with C corp partners often have to use accrual once they cross the threshold.
For most contractors and service businesses in Snohomish County, you have a choice. You also have to be consistent. Once you pick a method on your tax return, switching takes IRS approval through Form 3115.
The biggest advantage is simplicity. There is nothing to track except what hits the bank. The books are easy to maintain and they line up with what you can see in your account.
Cash basis can also help with tax timing. If you have a big invoice going out at year end, holding off on collection until January pushes that income into next year. That is real tax planning small business owners actually use.
The downsides show up when you want to understand performance. Cash basis can make a great month look terrible if a big bill happened to clear that month. It can also hide problems. A business can look profitable in cash terms while accounts payable quietly piles up.
Accrual basis tells you what the business actually earned and what it actually owes. Margins are real. Trends are real. You can look at a month and know whether the work that happened in that month was profitable.
That is why CPAs, banks, and CFO-level advisors prefer accrual. If you ever want a line of credit, a real loan, or a buyer for the business, accrual is the language people will want to see.
The downside is complexity. You have to track receivables and payables. You record income when invoices go out, not when checks come in. It is more work, and it requires someone who knows what they are doing.
A few rules of thumb hold up.
If you are a solo operator or a very small service business with no inventory, no big receivables, and short cycles between invoice and payment, cash basis usually works fine.
If you carry inventory, run multi month projects, deal with customer deposits, or have meaningful receivables and payables, accrual gives you a picture that is actually useful. Contractors and remodelers running jobs that span weeks or months almost always benefit from accrual.
A pattern we see a lot in Edmonds, Lynnwood, and Shoreline: small businesses file taxes on cash basis (for the timing benefit) and run their internal management reports on accrual (for the clarity). QuickBooks lets you switch any report between cash and accrual with one click, so this is more practical than it sounds.
The right method only matters if your books are clean enough to support it. Accrual on top of messy books is just messy books with extra steps.
Good bookkeeping sets up the chart of accounts, tracks receivables and payables properly, and gives you both views when you need them. If you are using your numbers for planning and growth, that is when CFO advisory starts to matter, and accrual becomes a near requirement.
The cash versus accrual question is not really about accounting theory. It is about whether you want your books to mirror your bank account or to tell you what your business actually did.
For taxes, cash basis often wins on timing. For running the business, accrual usually wins on clarity. A lot of well-run small businesses in Edmonds and Snohomish County use both, on purpose, for different jobs.
If you have no idea which method your books are on right now, that is worth fixing. Pick a method on purpose, build the bookkeeping around it, and use the numbers for something.
