Can You Afford Your Next Big Job? A Contractor’s Cash Check Before Saying Yes

A larger contract can look like the next step for your business. More revenue. A stronger backlog. Enough work to keep the crew moving.

Before you say yes, ask a second question: How much cash will this job use before it starts paying you back?

For a contractor, a profitable estimate and an affordable start date are two separate tests. You need both.

Start with the weeks before the first payment

The contract amount does not tell you when money will reach your account. Map the actual steps between starting work and receiving payment: the billing cutoff, required documents, approval process, payment terms, and expected processing time.

Then put your spending on the same calendar. Material deposits, payroll, equipment rentals, and subcontractor payments may arrive well before the first collection.

A cash forecast places expected receipts and payments in the periods when they will actually happen. That timing helps reveal shortages before bills come due. Community West Bank’s guide to cash flow projections explains how estimating incoming and outgoing cash can help a business identify its working capital needs.

For your bid decision, apply that calculation weekly and check the sequence of large payments within each week.

A $200,000 job can still create a $25,000 cash gap

Consider this illustrative example, not a client result or an industry benchmark.

You are considering a $200,000 contract with estimated direct job costs of $150,000. That leaves $50,000 of estimated gross profit before company overhead, financing costs, and taxes.

After protecting the cash needed for existing work and your operating reserve, you have $40,000 available to support this new job.

Here is the forecast through the first expected customer payment:

The job has a projected 25% gross margin, but this opening-period forecast shows a $25,000 funding gap before the first collection.

The positive balance in week five does not pay the bills in weeks three and four. If week-five spending clears before the customer payment, the temporary gap reaches $40,000.

That is why you need to check payment dates, not just a month-end total. You also need to extend the forecast through completion and final collection. This example covers only the opening weeks, not the entire job.

Run the new job alongside your existing backlog

A project forecast is useful, but the company pays the bills.

Add the proposed job to your 13-week company cash forecast. Include existing jobs, office expenses, debt payments, tax payments, and other committed outflows. Extend the planning horizon where the job runs longer.

Be careful with available cash. A customer payment sitting in the bank may still be needed to finish another project. An unused credit line is a separate funding source with borrowing conditions and repayment costs. Neither should quietly become “extra money.”

In the example, the $40,000 allocation already excludes existing obligations and the operating reserve. In a company-wide forecast, show those items explicitly and avoid deducting them twice.

Test what happens when the plan slips

Run a second version before committing. Change the assumptions that would hurt this particular job:

• Move the first customer payment two weeks later.
• Add the cash cost of another week of crew time and rentals.
• Delay retainage collection until a realistically supported release date.
• Keep disputed or unapproved change-order collections out of the dependable-receipts case.

These are planning scenarios, not predictions. Their purpose is to show whether one delay would force you to borrow, postpone a purchase, or compete with another job for payroll cash.

Track pending change orders separately, including the costs already incurred. A request for extra payment is not the same as an approved billing or a collection date.

Fix the funding plan before accepting the start date

If the forecast shows a gap, identify a specific solution.

Could the customer agree to a mobilization payment or different billing milestones? Could deliveries be staged? Would the supplier agree to terms that better match collections? Could the start date move without disrupting other work?

If financing is necessary, confirm actual availability, conditions, interest, fees, and repayment timing before relying on it. Include those costs when evaluating the job.

A higher contract price may improve margin while leaving the early cash gap unchanged. The solution must address the timing problem too.

Bring three answers to the decision

Before committing, your owner, project manager, and accounting lead should be able to answer:

1. What is the expected profit after realistic remaining costs and overhead considerations?
2. What is the lowest projected company cash balance, and when does it occur?
3. What confirmed funding or agreed contract change covers the gap if collections slip?

If the third answer is “we will figure it out,” the funding plan is still unfinished.

More work should come with a plan for paying for it.

Before accepting a larger job, use contractor cash flow forecasting to compare payroll, materials and subcontractor payments with realistic collection dates. A profitable bid still needs a funding plan.
