Cash Basis vs Accrual Basis Bookkeeping: What It Means for Your Books
By 909 Bookkeeping
Cash basis records money when it hits the bank. Accrual records it when it is earned or owed. Here is the difference and how to pick.
What cash basis means
Cash basis is the simple one. You record a sale when the money comes in. You record a bill when the money goes out. The books follow the bank. If the bank moved it, it is in the books. If the bank did not, it is not.
This is easy to understand because it matches what you see when you log in to your bank. The profit number on a cash basis report is close to the cash you actually have. For a small business, that is often the number the owner wants.
What accrual basis means
Accrual basis records money when it is earned or owed, not when the cash moves. If you send an invoice today and the customer pays next month, the sale goes in this month. If a vendor bills you today and you pay next month, the cost goes in this month.
Accrual matches the work to the month it happened in. A sale shows up when you did the work. A cost shows up when you used the thing you paid for. The profit number on an accrual report shows how the month really went, even if the cash moved in a different month.
The difference in one month
| What happens | Cash basis | Accrual basis |
|---|---|---|
| You send a 5,000 dollar invoice | Not in the books yet | Sale recorded now |
| You get paid that 5,000 next month | Sale recorded then | Already recorded last month |
| A vendor bills you 2,000 dollars | Not in the books yet | Cost recorded now |
| You pay that 2,000 next month | Cost recorded then | Already recorded last month |
The difference shows up in the profit number. On cash basis, the month you get paid looks like a big win and the month you wait looks quiet. On accrual, each month shows the work that happened in it.
Which one you should use
Most small service businesses start on cash basis because it is simple and it matches the bank. As the business grows, or if you carry inventory, accrual often fits better, because it matches the work to the month and the cost of goods to the sale.
The choice can also affect your taxes, so it is worth a quick word with your CPA before you switch. We do not give tax advice. We keep your books on the basis you and your CPA choose, and we keep it consistent from month to month.
A made up example for teaching
How we do it
We are QuickBooks Online Accountants (QBOA), so we work in the accountant side of QuickBooks Online every day. We work in Xero too. We work inside your QuickBooks Online or Xero file. You do not have to switch. If you already use one of them, we log in there and do the work. If you have no software yet, we help you set one up.
We start with clean and reconciled books. That means we reconcile every account and sort every transaction before we move forward. We keep your books on the basis you and your CPA choose, and we keep it the same each month. We use read only access and we never ask for your bank password.
Then we close each month by the 10th. We categorize and reconcile in the first week. We send you one list of questions on day 8. We lock the period on day 10 and send your reports. The monthly routine matters more than the brand. Reconciled accounts, the same categories every time, and a month end close are what make the books trustworthy.
Mistakes we fix
- Mixing cash and accrual in the same set of books.
- Recording the sale in one month and the cost in another, so the profit is wrong.
- Switching basis partway through the year without telling your CPA.
- Forgetting to record an invoice or a bill because the cash had not moved yet.
- Reading a cash report and an accrual report as if they said the same thing.
