Why deposits, not revenue, size a facility

UnderwritingWorking capitalRevenue is an accounting outcome. Deposits are what actually arrives in the account, in the order it arrives. Only one of those tells you whether a business can carry a payment.
Almost every credit application opens with a revenue figure. It is the number owners quote, the number brokers lead with, and the number that appears at the top of a tax return. It is also, on its own, close to useless for deciding how much debt a business can service.
Revenue tells you what a business earned over a year. It does not tell you when the money arrived, whether it arrived at all, or what was already committed against it by the time it did. A company can book eight million dollars of revenue and still be unable to make a payment in February, because the revenue was recognised in November and collected in April.
What underwriting reads instead is the deposit history: the actual credits landing in the operating account, month by month, in the sequence they occurred. That record answers a different and more useful question. Not how much did this business earn, but how much passes through it, how regularly, and what is left after everything already in front of us has been paid.
The gap between earned and collected
The distance between revenue and deposits is not a rounding error. For businesses that invoice, it is structural. A staffing company pays its people weekly and gets paid by its clients in sixty days. A specialty contractor completes a phase, submits a progress billing, and waits through an approval cycle. A distributor buys inventory three months before the season it was bought for.
In each case the revenue is real and the business is healthy, but the cash arrives on a schedule that has nothing to do with when the obligations fall due. Growth makes this worse rather than better: every new contract widens the gap, because the costs come first and the collection comes later.
This is not a marginal concern. Across the Small Business Credit Survey, meeting operating expenses was the single most common reason firms sought financing, cited by 56% of applicants — ahead of pursuing an expansion or a new opportunity at 46%. Most businesses asking for credit are not funding a new venture. They are bridging the distance between work done and money received.
What the deposit record actually shows
Read properly, twelve months of bank statements answer questions a financial statement cannot.
Consistency. Are deposits steady, or does the business earn most of its money in a ten-week window? A seasonal pattern is not a problem, but it changes the structure. A payment sized to peak months will break the business in the trough.
Concentration. Do the deposits come from many customers or three? A book of receivables that is mostly one payer is a different risk from the same dollar amount spread across forty, and it needs different terms.
Direction of travel. Is this year larger than last, and is the trend inside the year rising or falling? A declining twelve months with a strong annual figure is a warning the annual figure conceals.
What is already leaving. Recurring debits are the part owners most often understate, not dishonestly but because they have stopped noticing them. The statements do not forget.
True revenue is smaller than stated revenue
There is a further adjustment. Not everything that lands in an operating account is revenue. Transfers between the company's own accounts, the proceeds of other advances, refunds, loans from an owner, and pass-through amounts collected on behalf of someone else all show up as credits. Counting them inflates the picture, sometimes substantially.
Underwriting strips them out to arrive at what is genuinely earned and genuinely available. A business showing four hundred thousand a month in total credits may have three hundred thousand in true revenue once transfers and the proceeds of a prior advance are removed. Sizing a facility against the larger number produces a payment the business cannot carry, which serves nobody.
This is also why a stated revenue figure that diverges sharply from annualised deposits is worth a conversation rather than an assumption. Either the deposits are incomplete — a second account nobody mentioned — or the revenue figure includes something that never turned into cash.
Capacity, then structure
Once the deposit record is understood, sizing becomes arithmetic rather than judgement. Total debt service is held to a share of monthly deposits. Whatever is already servicing comes out of that ceiling first. What remains is the capacity available for a new facility, and the facility is sized to fit inside it across a term that matches what the money is for.
Working the problem in this order has a useful property: it produces an honest answer in both directions. If the capacity is there, the structure follows. If existing obligations have already absorbed it, that shows up immediately, and the right conversation is about consolidating what is in place rather than adding to it.
Why it matters more than it used to
The consequences of getting this wrong are visible in the survey data. Sixty percent of firms that borrowed from online lenders reported that their actual borrowing costs came in higher than expected; only 4% found them lower. A facility sized against a revenue figure rather than a capacity calculation is one of the ways that happens. The payment looked serviceable against the annual number and was not serviceable against the month.
Meanwhile more businesses are going outside the banking system every year. The share of applicants seeking financing from online lenders rose from 17% in the 2020 survey to 29% in the 2025 survey. And the credit that is available is not meeting the need: 42% of applicants received the full amount they sought, 36% received some or most of it, and 22% received none at all.
That shortfall is the argument for reading the file properly rather than faster. A business that does not fit is better served by a decline with a reason attached than by a facility sized against the wrong number.
What this means in practice
If you are preparing a request, send the statements. All of the operating accounts, twelve months, unedited. They are more persuasive than a summary, because they are the same evidence the underwriter would reconstruct anyway, and they will raise the questions that matter at the start rather than three weeks in.
And be ready to explain the gap between what the business earned and what arrived. There is almost always a gap. Knowing why it exists is usually the difference between a file that reads well and one that does not.
