Cash vs. accrual accounting, explained simply

Every business keeps its books on one of two timing methods, and most small owners pick one without understanding what they chose. Cash and accrual accounting answer a single question differently: when do you record a sale or an expense — when the money moves, or when the work happens? That timing difference changes what your financial statements say, when income shows up for tax, and how clearly you can see whether the business is actually healthy.

Cash-basis accounting

Cash basis records income when the money hits your account and expenses when you actually pay them. Invoice a client in March, get paid in May, and the income counts in May. It is simple, it mirrors your bank balance, and it is how most freelancers and very small businesses naturally think. Its weakness: it can distort reality, because a big December invoice paid in January makes December look poor and January look great, regardless of when the work was really done.

Accrual-basis accounting

Accrual basis records income when you earn it and expenses when you incur them, regardless of when cash changes hands. Deliver the project in March and the revenue counts in March, even if payment arrives in May. It matches revenue to the costs of producing it, giving a truer picture of profitability in each period. Its cost: more complexity, and the possibility of owing tax on income you have earned but not yet collected.

Which one should you use

• Most freelancers and small service businesses use cash basis: it is simple, matches the bank, and is often permitted for businesses under the size thresholds the IRS sets.
• Businesses that carry inventory, extend credit heavily, or want a true profitability picture often benefit from accrual, and larger businesses may be required to use it.
• You can keep books on accrual for management insight while filing taxes on cash basis if eligible — many owners want the clearer picture internally and the simpler tax treatment externally.
• Switching methods later is possible but involves an IRS process, so it is worth choosing deliberately and confirming eligibility with a CPA.

The bottom line

Cash accounting is simpler and ties tax to money actually received; accrual accounting is more complex but matches income to the work that earned it and shows truer period-by-period profitability. Most small service businesses reasonably start on cash basis, sometimes viewing accrual-style reports for management. The right choice depends on your size, whether you carry inventory, and IRS eligibility rules — so pick deliberately and let a CPA confirm you qualify for the method you want.
