A project can look profitable on the estimate and still put pressure on cash halfway through. Materials arrive before the customer pays. Payroll continues while an invoice waits for approval. A small change in scope becomes a larger purchase than anyone expected.
For a project-based business, the timing matters as much as the total. The estimate, purchasing plan and billing schedule need to describe the same job.
Before starting the next project, walk through the sequence with the people responsible for delivering and paying for it. The aim is to see the commitments before they become a surprise.
Map the job from start to final collection.
List the major stages: ordering materials, mobilizing the team, completing a milestone, submitting an invoice and receiving payment. Put expected dates next to each. Separate a promised payment date from an assumption about when the money may arrive.
A project schedule might already contain most of this information, but the financial view often sits elsewhere. Bring them together. The person managing the job should be able to recognize the work behind the cash forecast.
Include the steps between completing work and getting paid. A customer may require an inspection, approval or supporting documents before accepting an invoice. Those steps can move the collection date even when the work itself is on time.
Look at the commitments that come first.
Materials, subcontractors and payroll may need to be paid before the related customer receipt. Identify which commitments can move and which are fixed. An expected receipt should not be treated as available cash simply because it appears in the same month as a payment.
As a simple example, imagine a project that requires a $12,000 materials payment before an $18,000 progress payment is expected. The larger receipt does not remove the need to fund the earlier commitment. The business needs to understand the timing gap alongside its other obligations.
This example is about timing, not a recommendation for a particular deposit or billing structure. Contract terms, customer requirements and the nature of the work all affect what is appropriate.
Keep changes visible.
When the scope changes, update the estimate, purchasing plan and billing information together. A change that reaches the job site but not the office can create costs that are missing from both the forecast and the invoice.
Agree on who records the change and who confirms its approval. Avoid relying on a conversation that only one person remembers. The right process should be practical enough for the team to use while work is moving.
Review the effect on timing as well as the amount. A new material may have a different delivery date. Extra work may move the milestone associated with billing. A small adjustment can change more than one part of the plan.
Consider the rest of the business.
A project rarely uses an empty bank account with nothing else happening. Other jobs, regular overhead and existing commitments also draw on cash. Review the project alongside the business-wide forecast rather than in isolation.
Ask what happens if the progress payment arrives later. Which commitments remain? Who follows up? What information would prompt the team to revisit purchasing or the schedule?
Use a realistic alternative rather than an extreme scenario chosen only to make the base case look comfortable. The point is to identify a useful action if the timing changes.
Review the actual sequence.
As the job progresses, compare the expected payments and receipts with what happened. Update the dates using the latest information from the project manager and office team. Record why a meaningful difference occurred.
After completion, look at the financial result and the process. Were changes captured promptly? Did invoices go out with the required documents? Which assumptions were most different from reality?
These observations can improve the next estimate and forecast. They also give the owner a better basis for discussing payment terms, scheduling and capacity with the appropriate advisers.
A regular project cash review does not have to be complicated. It needs reliable information, clear ownership and a place on the calendar. Start with the next job you are about to commit to and map when the cash actually moves.
Before the next project starts.
Bring the estimate, delivery schedule and expected billing milestones into the same review. Ask your accounting team where the timing assumptions need a closer look.
