If you’ve ever checked your bank account, felt like things were fine, and then got hit with a bunch of unpaid bills out of nowhere, you’ve already experienced the difference between cash and accrual accounting without knowing it. Most small business owners just pick a method when they’re starting out and never really think about it again. However, what works when your business is small doesn’t always work as things start to grow. So here’s a breakdown of both methods and how to know when it might be time to switch. In simple terms, cash accounting records income and expenses when money actually moves in or out of your account, while accrual accounting records them when they are earned or incurred, regardless of when cash changes hands. The method you use affects your financial statements, your taxes, and in some cases, you may not even get to choose.
What Is Cash Accounting?
Cash accounting is the method where you record income when money actually comes in and expenses when money actually goes out. If a client pays you in June, that’s June income. If you get a utility bill in June but pay it in July, that’s a July expense. It’s simple, it’s straightforward, and for a lot of small businesses just getting started, it works perfectly. You’re focused on your bank balance, how much is coming in, how much is going out, and cash accounting reflects that directly.
What cash accounting does well:
- Simple to maintain and easy to understand
- Lower bookkeeping complexity
- Gives a clear view of actual cash coming in and going out
- Works well for freelancers and small service businesses with low transaction volume
Where it starts to fall short:
- When you have unpaid invoices or vendor bills, your books don’t tell the full story
- Hard to do meaningful budgeting or forecasting
- Bank balance alone can become misleading as the business grows
- Lenders and investors generally prefer accrual-based financials
What Is Accrual Accounting?
Accrual accounting records income when it’s earned and expenses when they’re incurred, regardless of when cash actually moves. So if you make a sale in June but the customer has 30 days to pay, that’s still June revenue. And if you receive a utility bill in June but pay it in July, it shows up as a June expense. The result is a much more accurate picture of how your business is actually performing month to month, as June stays in June and July stays in July. You can look back at your financials and see which months were profitable, which were slow, and plan accordingly.
What accrual accounting does well:
- More accurate financial statements as income and expenses match the period they actually belong to
- Supports budgeting and forecasting based on real trends
- Stronger reporting for lenders and investors
- Better insight for strategic decisions at the controller level
- Makes it possible to track accounts receivable, accounts payable, inventory, and other balance sheet items properly
Where it’s more complex:
- More moving parts and higher bookkeeping complexity
- Requires understanding of balance sheet accounts, like accounts receivable and accounts payable
- Takes more time to set up and maintain properly

Which Industries Tend to Use Each Method?
Cash accounting works well for freelancers, consultants, and very small service businesses where transactions are straightforward and volume is low. For example, if you run a small business with 25 transactions a month, cash accounting is probably all you need.
Accrual accounting is generally the better fit for construction, manufacturing, retail, e-commerce, healthcare, property management, and any company looking to bring in investors or secure a line of credit. That said, carrying inventory does not automatically mean you have to use accrual accounting. Since the 2017 Tax Cuts and Jobs Act, businesses with average annual gross receipts under the IRS threshold ($32 million for 2026) can use cash accounting even if they carry inventory. Inventory is a strong reason accrual accounting gives you more useful financial information, but it is no longer something that forces the switch for most small businesses.
The Biggest Misconception: Profit Doesn’t Equal Cash
One of the most common things business owners get wrong is assuming that if the business is profitable, there should be cash in the bank. That’s not always true. A business can be profitable on paper and still have very little cash if customers haven’t paid yet. Under accrual accounting, that $400,000 in accounts receivable shows up as an asset on your balance sheet, but it’s not in your bank account. Cash accounting wouldn’t reflect that sale at all until the money actually arrives. That’s why looking at your financial statements through an accrual lens gives you a much fuller picture of where your business actually stands.
How Does This Affect Taxes?
The accounting method you choose affects when income and expenses are recognized for tax purposes, which means it can impact your taxable income in a given year. It also affects how useful your financial reports are when filing.
One thing worth knowing: QuickBooks Online can run reports using either method, so you can toggle between cash and accrual views. But just changing the report setting doesn’t actually convert your books, as a proper transition from cash to accrual accounting requires cleaning up the balance sheet, including accounts receivable, accounts payable, prepaids, inventory, fixed assets, and accrued expenses.
So, When Should You Switch?
There’s no one-size-fits-all answer, but here are some clear signs it might be time to move from cash to accrual accounting:
- You have customers who pay on net 30 or net 60 terms
- You have vendor bills that don’t get paid the same month they come in
- You’re trying to get a business loan or bring in investors
- You want to do real budgeting and forecasting based on monthly trends
- Your transaction volume is growing, and your bank balance alone isn’t telling the full story
On the flip side, if you’re a freelancer or a very small service business with straightforward transactions and low volume, cash accounting might still be perfectly fine for where you are right now.
But here’s something a lot of business owners don’t realize. Sometimes you don’t get to choose. Under IRC Section 448, certain business types are required by law to use accrual accounting. C corporations, partnerships that have a C corporation as a partner, and tax shelters must switch to accrual once their average annual gross receipts over the prior three years exceed $32 million for 2026 and $31 million for 2025, with this threshold indexed annually by the IRS. If you are an S corporation or sole proprietor, you can stay on cash accounting at any size, regardless of how much revenue you bring in. But if you are structured as a C corp and your revenue is growing, this is not something you want to find out about after the fact. If you are not sure which rules apply to your business, that is exactly the kind of question worth getting answered before it becomes a problem.

Frequently Asked Questions
Does inventory require accrual accounting?
Not necessarily. Since the 2017 Tax Cuts and Jobs Act, businesses with average annual gross receipts under $32 million (the 2026 IRS threshold) can use cash accounting even if they carry inventory. Inventory is a reason accruals give you more useful financial information, but it does not automatically force the switch for most small businesses.
Can QuickBooks just switch my books from cash to accrual?
QuickBooks Online lets you toggle reports between cash and accrual views, but that does not actually convert your books. A real transition requires cleaning up your balance sheet, including accounts receivable, accounts payable, prepaids, inventory, fixed assets, and accrued expenses. It is a process best done with an experienced bookkeeper or accountant.
