When the Job Is Bigger Than Your Bank Line
You won the job. Your bank line wasn't built for it. That gap — between what your existing credit facility supports and what mobilization actually costs — is the single most common reason qualified contractors turn down work they're fully capable of doing. It's not a qualification problem. It's a timing and sizing problem, and it has a fix that doesn't require a bank re-underwrite.
- Bank lines and bonding aggregate limits are sized off trailing financial statements — they can lag a contractor's real growth by a full fiscal year or more.
- "Exceeding the line" usually shows up as a mobilization gap: equipment, crew, and initial material costs due before the first draw clears, while the existing facility is already committed to other active jobs.
- A bank line increase can take 60-90+ days to underwrite. A bid-to-notice-to-proceed window is often days to a few weeks — the timelines don't match.
- Byzfunder sizes additional working capital against deposit and revenue history plus the specific job's draw schedule, not a full bank-style re-underwrite.
- This is a bridge to the job's own draws, not a replacement for the bank line — and the two should be timed to avoid a repayment conflict.
Byzfunder is a direct lender — we fund contractors from our own balance sheet, not from a third party's credit committee, which is part of why we can move on a mobilization gap in days rather than months. We've funded thousands of small businesses since 2019, including construction and trade contractors navigating exactly this kind of capacity mismatch.
Why your bank line lags your growth
A bank line of credit and a surety bonding program are both sized on backward-looking data. That's not a criticism of your bank or your bonding agent — it's how those instruments are built to work, and it means a fast-growing contractor can outrun the paperwork before the paperwork catches up.
How bank lines get sized
Most construction bank lines are underwritten against trailing 12-24 months of financial statements: your balance sheet, your income statement, and specifically your working-capital ratio (current assets minus current liabilities, measured against your backlog). The bank is answering one question — can this contractor absorb a slow-pay job or a cost overrun without missing payroll — and it answers that question using last year's numbers, not this quarter's pipeline. A line set at, say, $500,000 based on a $4 million revenue year doesn't automatically move when you land a $2.5 million job that pushes you toward $7 million.
How bonding capacity gets sized
Surety bonding works the same way, one layer removed. Your bonding company reviews your work-in-progress schedule, your financial statements, and your track record to set an aggregate limit — the total dollar value of bonded work you can carry across all active jobs at once. That aggregate limit is a portfolio ceiling, not a per-job number. A single large job can eat most of your remaining capacity even if your balance sheet otherwise supports growth, because the bonding company is managing its total exposure to you, not just this job.
The result: fully qualified, still capacity-constrained
Here's the part that trips up good contractors: you can be completely qualified to perform the work — right trade, right crew, right experience, right safety record — and still be short on the two numbers (bank line, bonding aggregate) that were last recalculated based on a smaller version of your company. Winning the bigger job is proof the business is growing. The financial instruments just haven't been updated to reflect it yet.
What "exceeding the line" looks like on the ground
This rarely shows up as a dramatic funding shortfall. It shows up as a scheduling problem that becomes a cash problem.
Mobilization comes before the money. Before the first draw ever clears, you're paying for equipment mobilization or rental, ramping up crew (often adding people ahead of the job actually generating revenue), and making initial material buys — deposits on long-lead items, first delivery on commodity materials. None of that is reimbursed until the job produces its first verified draw, which on a general contractor or owner schedule can be 30, 45, sometimes 60 days out.
Your existing line is already working. The bank facility that could theoretically cover some of this is usually not sitting idle — it's allocated against other active jobs, retainage exposure, and normal working-capital swings. "I have a line" and "I have available capacity on that line right now" are two different facts, and a lot of contractors don't find out they're different until they need the room.
The gap is specific and temporary. This isn't a request for more money forever. It's a specific dollar gap between what mobilization costs and what the job's own draw schedule will start returning, for a specific window of weeks.
Why a bank re-underwrite doesn't fit the timeline
If your existing bank facility could simply be increased, that would be the cheapest fix — and it's worth asking. The problem is speed. A meaningful increase to a bank line typically means a fresh underwrite: updated financial statements, sometimes a full year-end review, updated work-in-progress schedules, and committee approval. That process commonly runs 60 to 90+ days, and can run longer if the bank wants a full annual review cycle to complete first.
A bid-to-notice-to-proceed window rarely gives you that kind of runway. Once you're awarded the job, mobilization often has to start within days to a few weeks — the owner or GC has their own schedule, and slow mobilization can put you in default on the very contract you just won. Waiting on a bank re-underwrite means either missing the mobilization window or covering it out of pocket in a way that strains the business anyway.
How Byzfunder's approach fits this specific gap
This is the case where a full bank-style re-underwrite is the wrong tool for the timeline, even though the bank line itself is the right tool for the business long-term.
Byzfunder is a direct lender — we fund from our own balance sheet, which means one application and one decision, not a submission that gets shopped or passed through layers of approval. Because we're not re-underwriting your entire banking relationship, we size funding differently:
- Deposit and revenue history, not a full financial-statement rebuild. We look at your business bank deposits and revenue trend to understand cash flow capacity — a faster read than a bank's trailing-statement underwrite.
- The specific job's draw schedule. We size the advance around when this job is expected to start throwing off its own draws, because that draw schedule is what pays the funding back.
- Speed matched to the mobilization window. Decisions and funding can happen in a timeframe that fits a notice-to-proceed clock, not a bank committee calendar.
- Credit is still reviewed. We look at FICO alongside deposits and revenue — our floor for MCA funding is 525, which is meaningfully more accessible than a bank facility increase for a contractor whose personal credit doesn't perfectly match their business's growth trajectory.
This is structured as an advance against future receivables at a factor rate, purchased based on your business's cash flow — not a bank loan and not a bond. It's a bridge to get equipment on site and crew mobilized, sized to be paid down as the job's own draws start coming in, not an open-ended facility running alongside your bank line indefinitely.
Stacking: carrying a bank line and a funding facility at the same time
Plenty of contractors carry a bank line for steady-state working capital and use a separate funding facility for a specific job spike. That's a normal structure, not a red flag — but it has to be timed deliberately:
- Sequence the repayment, don't let it collide. If your bank facility has a repayment schedule or a sweep on deposits, the funding facility needs a remittance structure that doesn't compete with that for the same dollars in the same week.
- Match the term to the job, not the relationship. The funding should run for the length of the mobilization-to-draw gap on this job — weeks to a few months, typically — not for the life of the contract. Once the job's draws are flowing, the bridge has done its job.
- Talk to your banker. Most bank covenants don't prohibit a short-term working-capital advance tied to a specific contract, but it's worth confirming rather than assuming, especially if your line has a borrowing-base or debt-covenant structure.
Size the funding to the gap, not the job
The instinct is to ask for funding equal to the full contract value. That's the wrong number. What actually needs covering is the mobilization-to-first-draw gap — equipment, initial crew ramp, first material buys — for the specific weeks before the job starts paying for itself. Sizing to the whole project value means carrying (and paying a factor rate on) capital you don't need for most of the job's life. Sizing to the gap keeps the advance proportional to the actual cash-flow problem.
| Option | Speed | Cost basis | Best for | Credit floor |
|---|---|---|---|---|
| Bank line increase | 60-90+ days | Interest rate, lowest cost if timeline allows | Permanent capacity growth, not a single urgent job | Strong personal + business credit, clean financials |
| SBA (e.g. 7(a) working capital) | Weeks to months | Interest rate, government-backed terms | Longer-lead expansion with time to spare | Generally higher; full documentation required |
| Bonding-company accommodation | Days to weeks (case by case) | No direct cost, but uses future bonding goodwill | One-off aggregate-limit exceptions with a strong surety relationship | Depends entirely on surety's confidence in the file |
| Byzfunder funding | As fast as 24-48 hours to fund | Factor rate on the advance, not an interest rate | Bridging mobilization to a job's specific first draw | 525+ FICO; credit is still reviewed alongside deposits/revenue |
A worked example
The numbers below are illustrative only — every file is different, and actual terms depend on your deposits, revenue, and the specifics of the job.
A general contractor with an existing $400,000 bank line — already about 70% committed to two active jobs — wins a $3.2 million commercial buildout. Mobilization requires roughly $180,000 up front: equipment rental deposits, bringing on two additional crews ahead of schedule, and the first material order on long-lead mechanical components. The GC's payment schedule puts the first verified draw at day 40.
The contractor's remaining available bank capacity is around $120,000 — short of the $180,000 mobilization need, and a formal line increase request would take 60-90 days to clear underwriting, well past the day-10 mobilization deadline in the notice to proceed. Byzfunder reviews deposit history and the job's draw schedule and structures an advance sized to the roughly $60,000 shortfall between available bank capacity and mobilization cost, with remittance timed against the expected day-40 draw rather than running indefinitely. The bank line stays intact for the contractor's other two jobs; the funding facility closes out once the first draw lands.
What Byzfunder looks at for a file like this
For a mobilization-gap request, we're primarily reviewing:
- Business bank deposits and revenue trend — the core read on cash-flow capacity
- Time in business — an established operating history on the trade
- FICO — credit is still reviewed; our floor for MCA funding is 525
- The job's draw schedule — how the gap will actually get repaid, since that's the basis for sizing the advance
- You've been awarded (or are bidding) a job larger than your current bank line or bonding aggregate comfortably supports
- Your business has consistent deposit/revenue history to show
- FICO of 525 or above
- You need capital specifically to bridge mobilization to the job's first draw — not open-ended financing
FAQ
Will this affect my bonding capacity? No — funding sized against deposits and revenue is separate from your surety relationship and doesn't factor into your bonding company's aggregate-limit calculation the way additional debt disclosed on your financial statements might. Talk to your bonding agent about your specific program, since sureties vary in how they treat short-term working capital.
Can I use this alongside my bank line? Yes, contractors commonly carry both. The key is timing — the funding facility's remittance schedule should be structured so it doesn't compete with your bank line's repayment or sweep terms in the same week.
What if my bank already said no to a line increase? A bank decline on a line increase isn't the same review as ours. We're looking at deposit and revenue history and the specific job's draw schedule, not re-underwriting your full banking relationship — a bank "no" on a line increase doesn't automatically mean "no" here.
How fast can this actually close? Funding can move in as fast as 24-48 hours once your file is complete, which is built to fit a notice-to-proceed mobilization window rather than a bank underwriting cycle.
Is this a loan? No. This is a purchase of a portion of your future receivables at a factor rate — not a loan, not an interest rate, and not additional debt on your balance sheet in the way a bank loan would show up.
What happens after the job's first draw comes in? Remittance is structured against your ongoing revenue, and the facility is meant to close out once the job is generating its own cash flow — it's a bridge for the mobilization window, not a permanent replacement for your bank line.
Does this replace my bank line long-term? No. Your bank line is still the right tool for steady-state working capital. This is specifically for the gap on a single job that outsizes your current capacity while your bank facility and bonding program catch up to your growth.
The gap doesn't have to cost you the job
A job bigger than your current bank line isn't a sign you're not ready — it's a sign your financing hasn't caught up to your growth yet. Byzfunder funds directly from our own balance sheet, sized to the specific mobilization gap and the job's own draw schedule, so a notice-to-proceed clock doesn't force you to choose between missing the window and straining the business.
