How contractor funding underwriting actually works (and why bank-declined contractors still qualify)

Contractor funding approval hinges mostly on consistent revenue, time in business, and existing debt load — not your credit score alone. That's the single biggest thing contractors get wrong when they assume a bank decline means they're unfundable everywhere. It usually just means they got measured against the wrong yardstick.

Why bank-declined contractors still get funded

A construction business can be doing $80,000 a month in revenue, paying every sub on time, and still get a form-letter decline from a bank. That's not a contradiction — it's how bank underwriting is built.

Banks and SBA lenders underwrite around personal creditworthiness and collateral, not the pulse of the business today. A 640 credit score, a slow season two years ago, or not having two full years of clean tax returns can sink an application even when the business itself is healthy right now. Federal Reserve Small Business Credit Survey data has consistently shown construction and other capital-intensive small firms report some of the highest financing-application denial rates of any industry segment, largely because these firms are asset-heavy and cash-flow-lumpy in ways that don't map cleanly onto traditional bank credit boxes.

Revenue-based funders — including direct funders like Byzfunder — start from a different question. Instead of "what's your credit history and what can you pledge as collateral," the question is "what does the money actually moving through your business bank account tell us about your ability to handle funding today." That's why a contractor who just got declined by a bank can still walk away funded within a day. Different underwriting model, different bar.

If you want the fuller picture of how this plays out specifically for contractors, see the construction business loans hub and loans for contractors. And if a bank decline is already on your record, business loans for bad credit walks through how that changes (and doesn't change) your options.

What banks and SBA lenders actually check

Traditional underwriting is built around risk-averse, collateral-first logic. That's appropriate for a 10-year term loan at a low rate — but it filters out a lot of good contractors along the way. Here's what's actually on the checklist:

• Personal credit score, typically 680+ for competitive bank terms, higher still for SBA
• Two or more years of business tax returns, showing consistent (ideally growing) profitability
• Collateral — equipment, real estate, or a personal guarantee with teeth
• Debt-to-income and existing liabilities, evaluated conservatively
• Time in business, usually 2+ years minimum, sometimes 3
• A clean personal financial history — no recent bankruptcies, liens, or major derogatory marks

None of that measures whether your business is making money right now. A contractor who incorporated 18 months ago after years as a sub, who just landed his biggest contract yet, checks almost none of those boxes — and gets declined regardless of how strong this year is turning out.

What revenue-based funders check instead

This is where the model flips. A revenue-based funder underwrites the business as it exists today, using primary source data instead of a two-year-old tax return.

Business bank statements (typically the last 3–6 months) are the core of the file. Underwriters are reading them for:

• Average daily balance — is there consistent cash sitting in the account, or does it hit zero every few days?
• Deposit consistency — are revenue deposits regular and trending flat-to-up, or wildly erratic?
• NSFs and overdrafts — a few occasional ones aren't disqualifying; a pattern of them signals real cash strain
• Existing MCA or advance payments — how much of the daily/weekly cash flow is already committed to other funders

Beyond the bank statements, funders also look at:

• Time in business — generally 6+ months minimum, with stronger terms the longer you've operated
• Monthly revenue — enough consistent volume to support a repayment structure sized to your cash flow
• Credit score — checked, but as one input among several, not a gate. Byzfunder's own minimums run as low as a 525 FICO for MCA and 550 for ByzFlex
• Existing debt load — not disqualifying by itself, but it affects how much new funding makes sense on top of what's already committed

The honest caveat: funding decisions get stronger the more of these boxes you check. A contractor who's strong on at least two of three — credit, time in business, revenue — with a reasonable existing debt load, is going to see the best offers. A contractor who's thin everywhere (brand-new business, weak credit, inconsistent deposits, and already stacked with advances) is a harder file for anyone to fund responsibly. This isn't a sales pitch that everyone qualifies — it's a description of how the math actually works.

Bank/SBA vs. revenue-based funder — what they underwrite

What documents you'll actually need

The revenue-based application file is deliberately lean compared to a bank package. Typically:

• 3–6 months of business bank statements (the single most important document)
• A voided check or bank letter for funding setup
• Basic business information — legal entity name, time in business, industry
• Driver's license or government ID for the business owner
• A breakdown of any existing advances or business debt, if applicable

There's usually no requirement for tax returns, a business plan, or collateral documentation — which is exactly why the process moves so much faster than a bank application. If you want a deeper checklist tied specifically to revenue-based products, see revenue-based financing requirements.

What existing debt does to your file

Contractors who already have an MCA or advance running often assume it automatically disqualifies them from more funding. It doesn't — but it matters.

Underwriters look at stacking — how much of your daily or weekly cash flow is already committed to existing advance payments. If that number is already high relative to your deposits, taking on additional funding on top of it can strain cash flow rather than help it. A responsible underwriting process accounts for this and sizes any new offer to what the business's current cash flow can actually support — not just what's technically possible to fund.

This is also why the honest answer to "does an existing MCA disqualify me" is: not automatically, but it changes the math, and it's worth being upfront about it in your application rather than having it surface as a surprise in your bank statements.

Timeline: from application to funds

Once your documents are submitted, a revenue-based funding decision typically comes back same-day to within 24 hours. That's a function of the underwriting model — reading bank statements and current business data is a faster, more mechanical process than evaluating years of tax history, collateral value, and a full credit file.

Compare that to a bank or SBA timeline, which commonly runs several weeks for a straightforward small-business loan and can stretch to a few months for SBA products that require additional documentation, appraisal, or committee approval. For a contractor who needs to cover payroll before a draw comes in, or put a deposit down on materials for a job that starts next week, that difference in speed is often the deciding factor — not the pricing.

Bottom line

Bank and SBA underwriting is built to measure a contractor's history — personal credit, years of tax returns, collateral. Revenue-based funders measure the business as it's performing right now, through bank deposits, time in business, and existing debt load. Neither model is universally "better" — they answer different questions, at different speeds, at different costs. A contractor with strong personal credit and the patience for a multi-month process may still come out ahead with a bank or SBA loan. A contractor whose credit doesn't reflect a genuinely healthy, revenue-generating business — or who simply needs capital faster than a bank can move — is often better served by a funder that reads the business through its bank account instead of its credit file.

FAQ

What credit score do I need for contractor funding? For a bank or SBA loan, expect to need a 680+ personal credit score for competitive terms. For revenue-based funding from a direct funder, credit is checked but isn't the primary gate — Byzfunder's minimums run as low as 525 FICO for MCA and 550 for ByzFlex, with the rest of the decision built around business bank deposits and time in business.

Can I qualify with bad credit? Often, yes — if the underlying business is healthy. Revenue-based funders weigh consistent deposits, time in business, and manageable existing debt load alongside credit, rather than using credit score as a hard cutoff. See business loans for bad credit for more detail on how that works in practice.

What documents are required? Typically 3–6 months of business bank statements, a voided check or bank letter, basic business information, owner ID, and a summary of any existing advances. No tax returns, business plan, or collateral documentation required for revenue-based products.

How long does approval take? Once your documents are submitted, decisions on revenue-based funding are typically same-day to within 24 hours. Bank and SBA loans commonly take several weeks to a few months.

Will applying hurt my credit? A revenue-based funding application generally does not require the kind of hard credit pull that meaningfully impacts your score the way a bank loan application can. The primary review is your business bank statements, not a deep credit file pull.

Does an existing MCA disqualify me? Not automatically. Underwriters look at how much of your cash flow is already committed to existing advances (stacking) and size any new offer around what your current revenue can support. Being upfront about existing debt in your application leads to a more accurate, faster decision.

What revenue do I need to qualify? There's no single universal number — it depends on your industry, time in business, and existing obligations — but consistent monthly deposits matter far more than hitting one specific revenue threshold. A contractor with steady, predictable deposits will generally see stronger offers than one with the same total revenue spread unevenly across the month.

Is a merchant cash advance a loan? No. An MCA is a purchase of a portion of your future receivables in exchange for upfront capital, repaid via a factor rate — not an interest-bearing loan. See how does a merchant cash advance work for the full mechanics.
