A seasonal business applying for credit in its slow quarter has a specific problem. The three most recent months look like collapse, the owner knows they are ordinary, and the file arrives with no evidence of which is true. Underwriters see both situations regularly and they do not assume.
How does a lender read a seasonal decline?
An underwriter looking at falling revenue asks one question: is this a cycle or a trend? Without evidence, the conservative answer is a trend, because a business in decline and a business in its slow season produce identical recent statements. The burden of distinguishing them sits with the borrower.
This is not scepticism about your business. It is the default reading of an ambiguous data set.
A worked example
A landscaping and grounds-maintenance company, revenue in thousands:
| Month | Revenue | Month | Revenue |
|---|---|---|---|
| January | $480 | July | $1,090 |
| February | $510 | August | $940 |
| March | $720 | September | $780 |
| April | $910 | October | $620 |
| May | $1,050 | November | $500 |
| June | $1,120 | December | $430 |
The year totals $9,150,000. April through September produces $5,890,000, which is 64% of annual revenue in six months.
Now apply for credit in January. The most recent three months are October, November, and December: $1,550,000, against a June peak of $1,120,000 in a single month. December revenue is 62% below the June peak. Annualise the last quarter and the business looks like a $6.2M company shrinking fast. Look at the full year and it is a $9.15M company that had a normal winter.
Both readings come from the same ledger. The difference is the window.
What evidence actually settles it?
Four exhibits, and they are more persuasive together than separately.
- Three years of monthly revenue, same-month aligned. Not three annual totals. A grid where January 2024, January 2025, and January 2026 sit next to each other, so the reader can see the trough repeat.
- A monthly cash-flow forecast through the next full cycle, showing the drawdown and the repayment, with the assumptions stated.
- Trailing-twelve-month figures at several points, which strip the seasonality out entirely and show whether the business is actually growing.
- A written explanation of the driver. Weather, school calendars, harvest, retail holidays, government fiscal years. One paragraph naming the cause.
The same-month grid
This is the exhibit that does the most work, and almost nobody submits it.
| Month | 2024 | 2025 | 2026 |
|---|---|---|---|
| October | $571 | $598 | $620 |
| November | $465 | $482 | $500 |
| December | $402 | $418 | $430 |
| January | $441 | $462 | $480 |
Read down each column and the business collapses every autumn. Read across each row and every trough is higher than the one before it. The second reading is the true one, and it takes a table to see.
Why trailing twelve months matters here
A TTM figure covers exactly one full cycle, so the seasonality cancels out. Presenting TTM revenue and TTM EBITDA at three or four consecutive quarter-ends turns a jagged line into a readable trend, and it is the format most credit analysts are already building for themselves.
Give it to them computed. If your TTM has risen for six consecutive quarters, that fact is invisible in a monthly chart and unmistakable in a TTM one.
Does the structure need to change too?
Usually, yes, and this is where seasonal borrowers get themselves into trouble. A seasonal working-capital need is a revolver need. Financing it with amortising term debt means fixed principal payments landing in the months with the least cash, which is the exact mismatch described in line of credit vs term loan.
Two structural points worth raising with a lender directly. First, ask whether covenants can be tested on a trailing-twelve-month basis rather than quarterly, so a seasonal trough does not trip a test that measures a cycle. Second, check any availability trigger against your own annual low point, because a seasonal business can agree to a threshold it will cross every single year as ordinary course. That mechanism is covered in cash dominion in ABL.
What about the collateral swing?
Seasonal businesses do not just swing on revenue. Receivables and inventory swing with them, which means the borrowing base is smallest in the months the company needs it most. Build the seasonal availability curve before signing, not after, using the mechanics in borrowing base certificate.
If the curve shows availability falling below the need in month ten of the cycle, that is a structuring conversation to have while the term sheet is open.
When should you apply?
If there is a choice, apply on the way into the strong season rather than at the bottom. The recent statements are improving, the collateral is building, and the story you are telling is confirmed by the next month’s numbers rather than contradicted by them.
If there is no choice, and often there isn’t, lead with the same-month grid. Do not wait to be asked for it.
The short version
A seasonal trough and a business in decline look the same in a three-month window. The evidence that separates them is a same-month grid across three years, TTM figures at several points, and a stated cause. Bring all three, and match the structure to the cycle rather than to the calendar.
