Cash vs accrual accounting: a founder’s plain-English guide
The short version
- Cash basis records money when it actually moves; accrual records it when it’s earned or owed.
- Cash is simpler and fine for most small, owner-run businesses.
- Accrual gives a truer picture of profit — and is expected by investors and at scale.
- You can often start on cash and move to accrual as you grow.
"Should my books be cash or accrual?" sounds like a question only an accountant could love. But the answer quietly shapes how well you understand your own business — so it's worth two minutes of plain English.
Cash basis: money in, money out
On a cash basis, you record income when the money lands in your account and expenses when they leave it. That's it. It mirrors your bank balance, it's easy to follow, and for a freelancer or small service business it's usually all you need.
The limitation: it can paint a misleading picture. Invoice a big client in March but get paid in May, and your March looks empty while May looks like a windfall — even though the work happened in March.
Accrual basis: earned and owed
On an accrual basis, you record income when you earn it (you did the work, you sent the invoice) and expenses when you incur them — regardless of when cash moves. It takes more bookkeeping discipline, but it tells you what actually happened in a given month.
Which should you use?
- Solo, service-based, paid promptly → cash basis is usually fine.
- Inventory, subscriptions, or invoicing on net terms → accrual will serve you far better.
- Raising money or planning to → investors and lenders expect accrual; build the habit early.
The good news
This isn't a once-and-forever decision you have to agonise over alone. Many businesses start on cash and switch to accrual as they grow, and good bookkeeping software handles both. What matters is that your books are consistent, reconciled, and actually reflect reality — which is the part we take off your plate.
Want books you can actually trust — on the right basis for your business? That’s exactly what we do.
