The short answer
Larger commercial jobs ask an electrical contractor to fund materials and payroll for weeks before the first progress payment, then wait months for retention. A line of credit often covers materials and payroll, invoice factoring can turn approved pay applications into cash sooner and equipment financing fits lifts and trucks.
Start by mapping the job’s cash curve from contract terms, retention and payment timing. In California, retention on private contracts entered into on or after January 1, 2026 is generally capped at 5 percent, with exceptions. Providers make the credit decision and set every term.
Why a larger commercial job needs more cash than a smaller one
On a service call, you buy a few parts and collect within days. On a commercial job, you may buy switchgear, panels, wire and fixtures in the first weeks, pay a crew every week and bill once a month for work completed. Each billing then waits for the general contractor and owner to approve it, and a share is held back as retention until the end.
The work is there. The Bureau of Labor Statistics projects electrician employment to grow 9 percent from 2025 to 2035 and ties part of that demand to data centers that support artificial intelligence and to linking solar and wind generation to homes, businesses and the grid. BLS also notes that overtime is common, which adds to payroll on a job that is running hot.
Hypothetical example: the cash curve on a $600,000 subcontract
An electrical contractor takes a four month tenant improvement subcontract worth $600,000 with 5 percent retention. Its costs total $500,000, front loaded because long lead gear is bought early. It bills at the end of each month and is paid 30 days later.
| Month | Costs paid | Billed (paid next month, less 5%) | Payments received | Cash still out of pocket |
|---|---|---|---|---|
| Month 1 | $190,000 | $150,000 | $0 | $190,000 |
| Month 2 | $110,000 | $180,000 | $142,500 | $157,500 |
| Month 3 | $110,000 | $170,000 | $171,000 | $96,500 |
| Month 4 | $90,000 | $100,000 | $161,500 | $25,000 |
| Month 5 | $0 | None | $95,000 | Ahead by $70,000, with $30,000 of retention still to come |
Hypothetical round numbers, not a quote or a prediction. The job earns $100,000, but the contractor needs about $190,000 of its own cash or financing in the first month, and the last $30,000 arrives only after the project is complete. Any delay in approvals or a disputed change order pushes every figure in the right hand column higher.
Retention: the payment that arrives last
Retention, also called retainage, is the share of each progress payment the owner or general contractor withholds until the work is finished. It protects the payer, but it means part of your margin sits unpaid for the life of the job and beyond.
What California law now says about private projects
For private works of improvement under contracts entered into on or after January 1, 2026, California Civil Code section 8811 says retention withheld from any payment shall not exceed 5 percent of the payment, and total retention shall not exceed 5 percent of the contract price. Subcontracts cannot withhold a higher percentage than the owner’s contract with the direct contractor allows.
There are exceptions. The cap does not apply to residential projects that are not mixed use and do not exceed four stories, or where a subcontractor fails to furnish a performance and payment bond after written notice that one would be required.
Release timing is set as well. Under section 8812, an owner that withholds retention must pay it to the direct contractor within 45 days after completion of the work of improvement. Under section 8814, a direct contractor must pay each subcontractor its share within 10 days after receiving all or part of a retention payment. In a good faith dispute, either may withhold up to 150 percent of the disputed amount.
For progress payments, section 8800 requires an owner to pay an undisputed progress payment to the direct contractor within 30 days after notice demanding payment, unless they agreed otherwise in writing, with a penalty of 2 percent per month on amounts wrongfully withheld. Your subcontract may set different timing between you and the general contractor.
These are California rules for private projects. Public works and other states follow different rules, so read the retention and payment clauses in each contract before you plan the job’s cash.
Which financing covers which part of the job?
A commercial job creates several different gaps. Matching each to a structure keeps you from paying for money you do not need, or running short when a billing is late. Products and terms vary by provider.
A line of credit for materials and payroll
Draw on a business line of credit as gear is ordered or payroll comes due, and repay it as progress payments arrive. On the example job, the balance would rise in month 1 and fall over months 2 to 4. A line is most useful when it is in place before you bid the next large job, not after the award.
Invoice factoring for approved pay applications
With invoice factoring, you sell an approved billing to a factoring company for an advance, and it collects from the general contractor or owner. Factoring is a sale of receivables, not a loan, and its fees reduce what you collect. The Uniform Commercial Code (Article 9, section 406) lets your customer keep paying you until it is notified of the assignment; after that notice, only payment to the factoring company settles the debt.
Ask each provider how it treats retention, unapproved billings and change orders, and whether a single large general contractor is too much of your receivables. Our guides on factoring with one major customer and factoring government contract invoices cover those questions. If you already have a lender with a lien on your receivables, a factoring provider may need that lien released or subordinated.
Working capital for one job
Short-term working capital can cover the gap on a single project you can repay from billings already in sight. Some of it is revenue based financing, in which a provider buys a share of your future receivables; it is not a loan, and collections are often daily or weekly. Check that those payments still fit in a month when a pay application is late.
Equipment for bigger jobs
Lifts, wire pullers, trenchers and an extra truck can be paid for over their useful life with equipment financing, which keeps your line free for materials and payroll.
If time allows, SBA describes a Contract CAPLine under its 7(a) program that finances the costs of one or more specific contracts. It may be revolving or non revolving and the maximum CAPLine maturity is 10 years; both SBA rules and the lender’s own standards apply. See our SBA loan page for more.
Bonding capacity and financing go together
Larger commercial and public jobs often require bonds, and a contractor that cannot be bonded cannot bid on those jobs. SBA guarantees bid, performance and payment surety bonds issued by certain surety companies, which lets them serve small businesses that might not meet other sureties’ criteria. SBA lists eligibility for contracts of up to $9 million for non federal work and up to $14 million for federal contracts.
SBA notes that applicants must also meet the surety company’s credit, capacity and character requirements. Financing and bonding draw on the same story: clean financial statements, a realistic backlog and enough working capital to finish the job. Plan both before you bid, because taking on financing can change how a surety views your capacity.
Project documents providers may ask for
Approval standards differ from one provider to the next, and no single credit score, revenue figure or years in business applies everywhere. Some providers restrict construction trades or require proof of licensing; BLS notes that most states require electricians to be licensed. For a commercial job, the project paperwork often matters as much as your bank statements.
Signed contract or subcontract
Shows the contract value, billing schedule, retention percentage and payment terms.
Schedule of values
Breaks the job into line items so each billing can be checked against work completed.
Pay applications and approvals
Approved billings are what factoring providers buy and what a line is repaid from.
Change orders
Signed change orders support added billings. Unsigned ones are harder to finance or collect.
Lien releases
Conditional and unconditional releases that track what has been paid on the job.
Receivables aging and backlog
Who owes you, for how long, and what signed work is still ahead.

How to evaluate financing for a specific job
- 1
Map the job’s cash curve
Lay out costs and expected payments month by month, as in the example above, and find the peak amount you will be out of pocket.
- 2
Read the payment and retention terms
Note the billing date, approval process, payment timing, retention percentage and when retention is released.
- 3
Match each gap to a structure
Materials and payroll to a line or working capital, approved billings to factoring, long-lived equipment to equipment financing.
- 4
Compare complete offers
Funds received after fees, total repayment or total fees, payment amount and frequency, estimated APR, UCC filings, guarantees and prepayment terms.
- 5
Stress test a late payment
Assume one pay application arrives 30 days late and one change order is disputed. If the plan breaks, reduce the amount or change the structure.
To see how fees and payment frequency change the real cost of short-term financing, read how to compare working capital costs. If you are weighing receivables funding against a revolving line, see receivables funding vs. a credit line.
When to pass on financing a larger job
Financing makes sense when it carries a profitable job from award to collection. It does not fix a job that was underbid, and it adds cost to a job with uncertain payment.
Think twice when the margin would not survive the financing cost, when the general contractor has a history of slow or disputed payments, when the job would make one customer most of your receivables, or when the schedule depends on gear with an uncertain delivery date. In those cases, a smaller job, a negotiated deposit for long lead materials or a joint check arrangement with your supplier may serve you better than more financing.
Correia Financial brokers financing rather than lending it: third party providers review each request, make the credit decision and set the terms.
Frequently asked questions
Can I factor a pay application before it is approved?
It depends on the provider. An approved pay application shows the general contractor or owner has accepted the work, so ask each provider whether it will advance against billings that are not yet approved, and when.
Can retention be financed?
Some providers treat retention differently from the current billing because it is not payable until the project is complete. Ask how retention is handled before you count on it, and plan for it to arrive last.
How much retention can be withheld on a California private project?
For private works contracts entered into on or after January 1, 2026, Civil Code section 8811 caps retention at 5 percent of each payment and of the contract price, with exceptions for certain residential projects and for subcontractors who fail to furnish a required bond.
Will the general contractor know I am factoring?
Usually, yes. The general contractor is typically notified to pay the factoring company, and once it receives that notice it can no longer settle the billing by paying you.
Should I use a line of credit or factoring for commercial jobs?
A line of credit is a loan you draw and repay, and it is best set up before you bid. Factoring is a sale of approved invoices that relies heavily on your customer’s payment record. Compare both on total cost and estimated APR, and remember you can use each for a different gap.
Does financing affect my bonding capacity?
It can. Surety companies review credit, capacity and character, so new debt and its payments may factor into how much bonding they will support. Talk with your surety before you take on significant financing.
Who makes the credit decision if I apply through Correia Financial?
The provider does. Correia Financial is a brokerage: it reviews your business and your project, explores options with third party providers and explains any offer. Applying is no guarantee of approval or funding.
