Traditional accounting: Revenue − Expenses = Profit. Profit First: Revenue − Profit = Expenses. The reordering sounds trivial but produces radically different behaviour. When you allocate 5–10% of every dollar/pound/SGD to a profit account before paying any expenses, you force the business to live on what's left. Most owners who adopt Profit First report having more cash in six months than in the previous two years — not because revenue grew, but because the allocation discipline revealed what could be cut.

The "I'll Take Profit After Expenses" Trap#
The traditional model: revenue comes in, expenses get paid, whatever's left is profit. In practice, "whatever's left" is usually very little — because expenses expand to consume available cash. There's always a reason to spend: new equipment that's almost necessary, a marketing push that might pay off, a staff hire that will be needed eventually. The business is profitable on paper (revenue exceeds expenses) but the owner has no cash and pays themselves last. They're essentially financing the business with their own salary — indefinitely.
The Profit First Account Structure#
Mike Michalowicz's Profit First method uses five bank accounts: Income (all revenue deposits here), Profit (5–10% of income transferred immediately), Owner Pay (your salary, 30–50% of income), Tax (15–25% of income, set aside for tax obligations), and Operating Expenses (what remains, used for all business costs). Every time income arrives, you transfer fixed percentages to each account before spending a pound on operations. Operating Expenses is the only account you spend from. The discipline of a fixed allocation — not a flexible "I'll take profit after I pay everyone else" — is what produces results.
Starting Allocations for an SMB#
Michalowicz recommends starting with small allocations and building up: Profit: 1%, Owner Pay: your current draw, Tax: 15%, Operating Expenses: the remainder. Each quarter, increase Profit by 1% and reduce Operating Expenses by 1%. Within three years, most businesses are running Profit allocations of 10–15% — meaning 10–15% of every pound of revenue is permanently protected as profit. The Operating Expenses pressure forces cost discipline that rarely happens voluntarily. The tax account eliminates year-end tax shock. The owner pay account separates your income from the business's liquidity.
Practical Implementation With AskBiz and Xero#
AskBiz tracks your Profit First allocations by connecting to your Xero bank feeds across all accounts. When income arrives in the Income account, AskBiz shows you the allocation amounts to transfer to each account — calculated at your set percentages. As the month progresses, you see how much Operating Expense remains available before the next income transfer. If expenses are running ahead of available OpEx allocation, AskBiz flags it before you overdraw the account. The discipline is built into the software, not just into your willpower.
What Happens After Six Months of Profit First#
The most common report from Profit First adopters: surprise at how much was wasted before. When Operating Expenses is constrained by a fixed allocation, every expenditure gets scrutinised. Subscriptions get cancelled. Inefficient staff schedules get tightened. The expensive supplier gets replaced by a comparable cheaper one. The owner also starts paying themselves properly for the first time — because Owner Pay is a ring-fenced account, not "whatever's left after expenses." After six months, most businesses have more cash in their Profit account than they expected, and a leaner cost structure than they thought possible.
Worked Example: A Tradesperson's First Year on Profit First#
A sole-trader electrician turning over £145,000/year had been paying himself "whatever was left" after materials, van costs, and a part-time admin assistant — some months £2,800, some months £600, with no pattern he could explain. He started Profit First with modest allocations: Profit 2%, Owner Pay £2,200/month fixed, Tax 20%, Operating Expenses the remainder. The first quarter was uncomfortable — Operating Expenses felt tight and he nearly abandoned the split when a van repair bill landed. But the discipline forced a decision he'd been avoiding: dropping a materials supplier charging roughly 9% above a comparable local alternative, saving around £2,600 over the following nine months. By month eight, his Profit account held £2,900 he hadn't consciously "saved" — it had simply never been available to spend because it moved out of Income before he saw it.
Adapting Profit First for Seasonal Businesses#
Businesses with strong seasonality — landscaping, tourism, retailers reliant on Q4 — need to adjust the pure Profit First model, which assumes relatively even income throughout the year. The fix is to calculate allocations against your annual average income rather than each month's actual income, and to build a larger buffer in the Operating Expenses account during peak months specifically to fund the lean months. A seasonal landscaping business earning 70% of its annual revenue between April and September should transfer a larger-than-proportional share to a reserve during those six months, so Owner Pay and Operating Expenses can stay level through the winter rather than swinging wildly with cash collected that week. AskBiz can apply your own historical seasonal pattern to smooth the allocation calculation automatically, rather than forcing a rigid percentage that doesn't fit how the business actually trades.
People also ask
Do I need to open multiple bank accounts for Profit First?
Ideally yes — separate accounts make the allocation visible and tangible. Most UK banks allow multiple current accounts for business use. Some digital banks (Starling, Monzo Business) support account "pots" that work identically without needing separate account numbers.
What if my operating expenses genuinely exceed the Profit First allocation?
Then your business has a structural cost problem that Profit First is correctly surfacing. The answer is not to abandon the method — it's to identify which costs can be cut or which revenue lines can be grown. Michalowicz is explicit: if OpEx is always too tight, the business model needs fixing, not the allocation percentages.
