Subcontractor vs. General Contractor Funding: What's Different

A general contractor and a subcontractor can work the exact same project and still have completely different funding problems. A GC needs capital to run payroll and overhead across several jobs at once while waiting on the owner to pay each draw. A sub needs capital to bridge the gap between finishing their scope and actually collecting — often including a final retainage release that doesn't land until months after the work is done. Same industry, same project, two different cash-flow shapes.

Byzfunder is a direct lender — we fund from our own balance sheet, not someone else's capital pool. That matters here because construction cash-flow timing is already complicated enough without adding a layperson underwriter who doesn't know what retainage is. One application, one decision, and we look at the file the way someone who's actually worked construction funding would look at it: differently depending on whether you're the GC holding the contract with the owner or the sub two tiers down.

Why retainage hits GCs and subs differently

Retainage — the owner (or GC) withholding a percentage of each payment, commonly 5-10%, until the work is substantially complete — exists to protect against unfinished or defective work. It's standard in commercial construction. But it doesn't sit evenly across the payment chain.

The GC is squeezed from both directions

A general contractor typically has retainage withheld by the owner on the overall contract, and simultaneously withholds retainage from every subcontractor on their scope. That means a GC's own retainage release depends on the owner being satisfied with the entire project — not just their piece — while the GC is also the one deciding when to release retainage down to subs. The GC is managing two retainage clocks at once: their own money coming from the owner, and the money they owe out to subs.

The sub waits longest, for money they can't accelerate

A subcontractor's retainage typically doesn't release until the GC collects final retainage from the owner and confirms punch-list and closeout across the whole project — work the sub has no visibility into and no control over. A sub can finish their scope on schedule, pass inspection, and still be waiting for their final 5-10% months later because another trade on the same job is behind, or the owner is slow to sign off on closeout. That's the retainage chain in practice: the sub is at the bottom, waiting on everyone above them to finish before their own held-back money moves.

Pay-when-paid vs. pay-if-paid: what these clauses actually do

Both clauses appear in sub-tier contracts, and both push payment risk downward — but they don't do the same thing.

• Pay-when-paid is a timing mechanism. It says the GC will pay the sub within a reasonable time after the GC is paid by the owner. The sub is still owed the money regardless — the clause just ties the payment schedule to the GC's own collection timeline instead of the sub's completion date.
• Pay-if-paid goes further: it attempts to make the GC's receipt of payment from the owner a condition of the obligation to pay the sub at all — meaning if the owner never pays (say, due to insolvency or dispute), the GC's position is that it owes the sub nothing. Whether a pay-if-paid clause actually holds up is state-dependent — some states restrict or void these clauses as against public policy, others enforce them if the contract language is clear. This isn't legal advice, and any sub relying on how their specific contract will be treated should have a construction attorney read it.

Either way, the practical effect is the same direction: payment risk from a slow or non-paying owner gets pushed down onto the sub, who had no relationship with the owner and no say in that risk. That's the mechanical reason subs disproportionately carry cash-flow exposure that has nothing to do with their own performance.

Who actually holds the cash-flow risk

In practice, the GC functions as the cash-flow intermediary on a project — collecting draws from the owner, paying overhead and multiple subs' invoices, and managing the timing gaps across several jobs running at once. A GC's funding problem is a portfolio problem: payroll and material costs across concurrent jobs, timed against a rolling set of owner draws.

A sub's funding problem is narrower but more exposed: they're dependent on the GC's payment discipline and on the GC actually collecting from the owner. A sub can do everything right — complete the scope, pass inspection, submit a clean invoice — and still be sitting on unpaid cash because of a dispute or delay two tiers up the chain that has nothing to do with their work. That's the core asymmetry: GCs manage risk across a portfolio; subs absorb risk from a chain they don't control.

Different roles, different funding shapes

Because the underlying cash-flow problem is different, the funding that actually fits is different too.

General contractors typically need capital that covers payroll and overhead across multiple concurrent jobs — not just one project's gap. A revolving facility that can be drawn against repeatedly, as new draws come in and go back out, tends to match how a GC actually operates day to day. This is where ByzFlex, Byzfunder's revenue-based revolving capital, tends to fit: draw what's needed, repay, draw again, without re-applying for a new advance every time a new job starts. FICO 550+ is the floor we look at for ByzFlex.

Subcontractors more often need a single, job-specific bridge — capital sized to cover the gap between finishing their scope and actually collecting, including the wait on final retainage. That's usually a one-time need tied to a specific receivable cycle rather than an ongoing portfolio. An MCA — a purchase of a subcontractor's future receivables at an agreed factor rate, not a loan — is often the better fit here: it's sized to the job in front of them, and repayment is structured against the business's incoming revenue rather than a fixed multi-job schedule. FICO 525+ is the floor we look at for MCA.

Subs also have a lever GCs generally don't: mechanics lien rights. If a sub isn't paid for completed work, filing a lien against the property can be a real point of leverage to get payment moving — state deadlines and requirements vary, so this is worth a conversation with a construction attorney, not something to rely on without understanding your state's specific rules. It doesn't replace bridge funding, but it's part of the toolkit that's specific to the sub's position in the chain.

A worked example (illustrative only)

GC scenario: A general contractor is running three concurrent jobs — one just hit a draw milestone, one is mid-build with payroll due weekly, and one is about to start and needs mobilization costs covered before the first owner draw comes in. Rather than applying for a new advance for each job, the GC uses a ByzFlex facility — draws capital as costs hit across the three jobs, repays as draws and receivables come in, and can draw again without restarting the process for the next job.

Sub scenario: An electrical subcontractor finished their scope on a commercial build six weeks ago. The GC paid the bulk of the invoice, but 8% retainage is being held until the whole project reaches closeout — which isn't expected for another two to three months because a separate trade is behind schedule. The sub still has payroll and material costs on their next job. Rather than waiting out the retainage timeline, the sub uses a single MCA sized to bridge that gap, repaid against incoming revenue from ongoing work.

These are illustrative examples only — actual advance amounts, factor rates, and terms are file-specific and not guaranteed.

What Byzfunder looks at for a file like this

Whether you're a GC or a sub, the review looks at the same core inputs, weighted differently depending on the funding shape that fits:

• Bank deposits and cash flow — recent statements showing revenue pattern, not just a single strong month.
• Time in business — an established operating history in construction specifically.
• FICO — 525+ floor for MCA, 550+ floor for ByzFlex. Credit is still reviewed as part of the file.
• Concurrent job load (GCs) — how many active contracts and draw schedules are running at once.
• Retainage and receivables position (subs) — what's outstanding, what's been invoiced, and roughly where in the collection cycle the business sits.

FAQ

I'm a sub waiting on retainage — can I get funded against it? Byzfunder doesn't fund against a specific retainage balance as collateral. What we look at is your overall bank deposit and revenue pattern, business history, and FICO. An MCA can bridge the cash-flow gap while you wait on retainage release, sized against your receivables and revenue rather than that one held-back amount.

Does a pay-if-paid clause affect my ability to qualify? Not directly — we're underwriting your business's deposit history and overall financial pattern, not auditing individual contract clauses. But it's worth knowing whether your contracts carry pay-when-paid or pay-if-paid language, since that affects how predictable your own collection timeline is, which is useful for you to know when sizing how much funding you actually need.

As a GC, can I get funding for multiple jobs at once? Yes — that's exactly the case ByzFlex is built for. Rather than a single advance tied to one job, ByzFlex is revenue-based revolving capital you can draw against as costs hit across concurrent jobs and repay as draws come in.

What's the difference between MCA and ByzFlex for a construction business? An MCA is a purchase of your future receivables at a factor rate — a single advance sized to your business, typically a fit for a discrete, job-specific gap. ByzFlex is revenue-based revolving capital that functions like a line of credit in practice — draw, repay, draw again — a fit for ongoing, multi-job cash-flow management.

Do I need to show a signed contract or purchase order to qualify? It helps us understand your pipeline, but qualification is based primarily on your bank deposit history, time in business, and FICO — not a single contract.

How fast can a subcontractor actually get funded once retainage is dragging? Timing depends on your file — documentation readiness, deposit history, and FICO all factor in. Because Byzfunder funds directly from its own balance sheet, there's one application and one decision rather than a submission being shopped to outside capital sources.

Is ByzFlex a line of credit? ByzFlex is revenue-based revolving capital — it functions like a line of credit in that you can draw and repay repeatedly, but it's structured and repaid against your business's revenue rather than a traditional bank line of credit product.
