What it means
Pure cash accounting records income when money arrives and expenses when money leaves. It is easy to operate and matches the bank statement, but it can make a profitable month look terrible simply because a delivery van was paid for in it.
The modification fixes exactly that problem. Purchases that provide benefit over several years are placed on the balance sheet and written off gradually, so the profit figure is no longer distorted by the timing of large one-off payments.
Businesses usually modify two or three specific items rather than inventing rules as they go. The common set is capitalising and depreciating fixed assets, recording long-term loans as liabilities with only the interest hitting the profit figure, and sometimes carrying inventory as an asset until it is sold.
The trade-off is comparability. The modified cash basis is not a recognised framework in the way that full accrual accounting is, so two businesses can both claim to use it and produce accounts built on different rules.
That is why the method is best suited to internal management reporting, very small companies and some professional practices. Lenders, investors and acquirers generally want accrual accounts, and many tax authorities set a revenue threshold above which a cash or modified cash basis is no longer permitted.
If a business expects to raise outside money within a few years, moving to full accruals early is usually cheaper than doing it under deadline pressure. Restating several years of history during due diligence is slow, and the numbers often move enough to reopen a negotiated price.
In practice
Real-world examples.
Example
A dental practice records fees when patients pay but capitalises a $180,000 scanner and depreciates it over six years at $30,000 a year. Monthly profit stays readable, whereas pure cash accounting would have shown a large loss in the month the scanner was bought.
Example
A landscaping company using the modified basis carries a $22,000 stock of paving slabs as an asset rather than an expense. When the slabs are used on a job in the following quarter, the cost lands in the same period as the revenue it helped earn.
Example
A firm preparing to sell discovers that its buyer will only work from accrual accounts. Its accountant restates three years of modified cash figures, and the revised earnings before interest and tax come out $210,000 lower once unpaid supplier bills are recognised.
Formula
Calculation
Modified cash profit = cash receipts - cash payments + capitalised asset purchases - depreciation + closing inventory adjustment
A consultancy receives $840,000 in cash during the year and pays out $610,000, giving a pure cash profit of $840,000 - $610,000 = $230,000.
Included in those payments is $60,000 for equipment with a five-year life. Under the modified basis the $60,000 is removed from expenses and a depreciation charge of $60,000 / 5 = $12,000 is recorded instead, so profit rises by $60,000 - $12,000 = $48,000 to $278,000.
The business also paid $40,000 for training materials that are still unsold at the year end. Carrying them as inventory adds $40,000, giving a modified cash profit of $278,000 + $40,000 = $318,000.
For comparison, full accrual accounting would also bring in $95,000 of invoiced but unpaid fees and $50,000 of unpaid supplier bills, producing $318,000 + $95,000 - $50,000 = $363,000. The $133,000 gap between the pure cash figure of $230,000 and the accrual figure of $363,000 shows how much the choice of basis can move the reported result.Case study
Seen in the real world.
The following is an illustrative and entirely fictional example. Ashcombe Veterinary Group, an invented three-clinic practice, ran its books on a pure cash basis and reported a loss of $40,000 in a quarter when it had paid $150,000 for new imaging equipment.
The bank, reading the quarterly management accounts, paused a facility renewal. The practice manager moved to a modified cash basis, capitalising the equipment over five years at $150,000 / 5 = $30,000 a year, or $7,500 a quarter. The same quarter then showed a profit of $150,000 - $7,500 - $40,000 = $102,500.
In this fictional case nothing about the underlying business had changed; only the timing of how one payment was recorded. The bank renewed the facility, and the practice adopted full accrual accounting two years later when it began preparing for an outside investment.
Watch out
Common mistakes.
- Assuming the modified cash basis is an officially defined framework, when it is a family of practical variations rather than a single set of rules.
- Applying the modification inconsistently, capitalising some equipment purchases and expensing others of similar size and life.
- Reporting modified cash figures to a lender or investor without saying so, which invites accusations of overstating profit once the basis is discovered.
Questions
People also ask.
Is the modified cash basis acceptable for tax?
It depends on the jurisdiction and the size of the business, since many tax authorities permit a cash or modified basis only below a revenue threshold.
How is it different from full accrual accounting?
Accrual accounting recognises all revenue when earned and all costs when incurred, while the modified basis applies that treatment only to selected long-term items.
Should a growing business switch to accruals?
Generally yes, once it carries meaningful receivables, payables or inventory, because at that point cash-based profit stops describing what the business actually earned.
