You are building a company and likely wearing every hat available. Eventually you have to look at the numbers. You might open your books and see two different options for how to track your money.
One makes sense intuitively. The other seems complicated.
Accrual accounting is an accounting method where revenue and expenses are recorded when they are incurred, regardless of when cash is actually exchanged. This stands in contrast to cash accounting, which only records transactions when money hits or leaves the bank account.
While it requires more effort to maintain, understanding accrual accounting is usually a non negotiable requirement for scaling a startup.
The Mechanics of Accrual
#The core philosophy here is matching. You want to match the revenue you earn to the expenses you spent to earn it within the same time period.
If you send an invoice to a customer in December for services rendered in December, accrual accounting says you earned that money in December.
It does not matter if the client waits until February to pay you. The value was created and delivered in December.
The same applies to your bills. If you hire a contractor who does work in June, you record that expense in June. It counts against your June revenue even if you do not pay their invoice until July.
This gives you a real look at profitability.
Comparing Accrual to Cash Accounting
#Most people run their personal lives on cash accounting. You look at your bank balance. If the money is there, you have it. If it is not, you do not.
Cash accounting is simple:

- Revenue is recorded only when payment is received.
- Expenses are recorded only when bills are paid.
Accrual accounting is more multidimensional:
- Revenue is recorded when earned (Accounts Receivable).
- Expenses are recorded when billed (Accounts Payable).
Consider a SaaS company that charges $12,000 upfront for an annual contract. Under cash accounting, you have a massive profit month followed by eleven months of zero revenue. Under accrual accounting, you recognize $1,000 of revenue each month for twelve months.
Why Startups Need Accrual
#If you plan to stay small or operate a simple service business with immediate payments, cash accounting might suffice. However, if you are building a startup with growth ambitions, you will likely need to switch to accrual.
Investors require it. Due diligence processes almost always demand accrual based financial statements because they show the true operational efficiency of the business.
It smooths out the peaks and valleys. It removes the noise of payment timing so you can answer the hard questions.
- Are our margins actually improving?
- Did that marketing spend really generate leads this month?
There is a trap here that founders must navigate. Accrual accounting tells you if you are profitable, but it does not tell you if you are solvent.
You can show a massive net profit on your Profit and Loss statement while having zero dollars in the bank because clients haven’t paid their invoices yet.
When you use accrual accounting, you must also religiously track your Cash Flow Statement. Do not confuse “earned revenue” with “cash on hand.”
As you build, ask yourself if your current financial reporting reflects the work you are doing today or just the banking transactions of yesterday. The answer usually dictates when it is time to make the switch.
