Contractors can reduce the amount they advance for materials by pricing early procurement costs before signing, negotiating payment milestones that the contract permits, and confirming required approvals and payments before releasing major purchases. Track committed costs separately from cash already paid so you can see both future exposure and the cash the job needs now.
TL;DR
- Collect customer payments before making major procurement commitments.
- Build the payment schedule around when cash leaves the business, not arbitrary percentages.
- Require payment and approval before releasing high-cost or nonreturnable materials.
- Compare committed costs and actual spending with the cash collected on each job.
- Make every deposit and milestone comply with the contract, customer requirements, and applicable payment rules.
Why do contractors end up fronting material costs?
Contractors often have to pay their suppliers for initial job costs before collecting sufficient funds from customers to cover those costs. The additional time required to order long-lead-time equipment or to have custom-fabricated products creates a significant gap. That’s why it’s important to track the following:
Committed cost
Costs the contractor has agreed to but may not have paid yet. A purchase order or fabrication release, for example, can create a financial obligation weeks before the final supplier invoice is due.
Cash paid
This is money that has already left the business for deposits, supplier invoices, or other job expenses.
Tracking both gives contractors a better picture of how much cash a job has already consumed and how much more they are committed to spending.
For example, a contractor may commit 35% of a project’s price to materials, equipment, and supplier deposits before work begins on site. If the customer has paid only 10%, the remaining 25% represents an unfunded commitment. It becomes a cash funding gap as supplier payments come due. The payment schedule should account for both when the contractor makes a commitment and when cash must leave the business.
At each major milestone, compare customer payments collected with costs committed and payments due before the next milestone. This shows how much future spending is uncovered and how much cash the contractor needs now. Where the contract permits, schedule customer payments before substantial supplier payments come due.
How much cash will the job need before the next customer payment?
Before signing the customer contract, build an expected cash flow chart for the job. Determine what you’ll commit to suppliers at each stage, and identify when you’ll need to pay them and when customer payments will arrive.
- Supplier deposits and equipment: What must you commit to suppliers before goods ship?
- Fabrication and freight: When do you receive your release, balance due, and delivery charge information for your initial billings?
- Subcontractors: Does a subcontractor require early payment?
- Early labor: What work will be performed prior to your first billable event?
- Payment timing: How long will approval and clearing take?
Separate contract value from cash requirements
Remember, contract value and cash requirements aren’t linear. Contractors should estimate when major costs will come due and negotiate a payment schedule that accounts for those cash needs.
Include committed costs, not only invoices already received
Purchase orders can commit substantial future spending before supplier invoices arrive. Track commitments and actual payments in the construction job-costing process.
When should contractors collect payment for major material purchases?
Make procurement contingent on a customer payment milestone. Size that payment to cover what you’ll owe before the next major milestone, including fabrication, raw materials, freight, and any other costs that come due before the customer’s next installment.
Create a real procurement gate
Customer approves work → Payment becomes due → Payment clears → Procurement is authorized → Materials are ordered
Put the approval and payment requirements in the contract. Then make them part of the purchasing process: before ordering major materials, the person responsible checks that the customer has approved the work and the required payment has been received.
How should contractors set progress payment milestones?
In general, most material-heavy projects will go far beyond an initial deposit and a final invoice. Consider using milestones that your customer can verify and that represent significant cost commitments tied to specific cost values.
| Possible milestone | Why it can support billing |
| Equipment ordered or fabrication released | A documented procurement commitment exists. |
| Materials delivered | Products reached the agreed location. |
| Mobilization or rough-in completed | A visible field stage is complete. |
| Installation or inspection completed | The customer can verify the result. |
| Substantial completion | The contract’s completion threshold is met. |
Four equal payments can still leave a contractor with a large cash gap if most material costs come due early in the job. Set payment milestones with those costs in mind, subject to the contract and applicable payment rules.
Can contractors bill for materials before installation?
On commercial jobs, contractors may be able to include materials stored on-site or off-site in a pay application (a formal request for payment for work completed and eligible materials stored for the project) before installation. The schedule of values identifies the material costs, and an AIA G702/G703-style application provides a place to show stored materials separately from completed work. Off-site storage generally requires the owner’s advance approval and additional protections, so check the contract before relying on this payment.
Give major equipment and fabricated materials clear, supportable values in the schedule. Avoid front-loading it with inflated early amounts: owners may reject a schedule that asks them to pay more than the early work and materials justify. Allow time for the pay application to be reviewed and paid before counting that money toward a supplier bill.
Why should procurement be a separate project stage?
For specialty contractors, procurement is financially significant work. Long-lead equipment may require engineering, approvals, supplier deposits, and fabrication months before installation.
Separating procurement from installation makes it easier to set payments around the job’s real cost curve.
How can contractors confirm payment before ordering materials?
Establish one internal rule: required payment received → procurement release approved. Give the rule an owner and an exception process.
Payment-status check
Confirm cleared payment before creating or approving the purchase order.
Procurement approval
Assign responsibility for releasing major or nonreturnable products.
Controlled exceptions
Let a named manager approve exceptions for strategic accounts or negotiated credit terms.
Recorded reason
Document why purchasing proceeded without the standard payment prerequisite.
What should contractors track to spot a cash gap?
Compare customer cash collected with incurred and committed costs throughout the job.
- Estimated, committed, and actual material cost: Whether purchasing remains within its allowance.
- Labor, time, and cost codes: How costs are developing before billing.
- Approved change orders: Whether added scope has entered billing.
- Amount invoiced and amount paid: Whether revenue has become usable cash.
- Remaining value and expected margin: What remains to bill and spend.
Together, these figures show whether a job is profitable on paper but still requires the contractor to cover costs before customer payments arrive.
A $200,000 project can be profitable and still strain cash flow if a contractor pays $70,000 in job costs after collecting only $20,000 from the customer. Late payments can widen that gap. In the QuickBooks 2026 Small Business Late Payments Report, 59% of small business owners surveyed said at least some of their invoices were overdue by 30 days or more, up from 47% the year before. Those waiting on unpaid invoices were owed $17,700 on average. And getting paid doesn’t always close the gap: 49% of owners said standard payment processing times still create moderate or critical cash-flow problems, even after the customer pays.
| Measure | Amount | Share of job value |
| Total job value | $200,000 | 100% |
| Job costs paid | $70,000 | 35% |
| Customer payments collected | $20,000 | 10% |
| Cash funding gap | $50,000 | 25% |
How can contractors bill promptly when a milestone is reached?
Once a milestone occurs, minimize the time between field completion, approval, and the payment request. In an interview, Carlos Mejia, principal at Delta Development Partners, said, “The field measures in today’s pour. HQ measures in monthly draw cycles.” A completed stage cannot trigger timely billing if the office does not know it has happened or lacks the documentation to support an invoice.
Milestone reached → Evidence recorded → Invoice issued → Customer notified
Common delays include missing field documentation, unsigned paperwork, manual invoice creation, and accounting learning about the milestone days later. A 30-day term becomes much longer when the invoice sits internally for another week.
How can contractors make it easier for customers to approve and pay?
Remove avoidable time between earning and receiving payment. Electronic signatures, digital approvals, online payments, portals, and automated reminders can shorten the path without changing the contract.
The practical test
Can the customer see what is due, approve the supporting document, and pay without waiting for someone to resend paperwork?
How can contractors avoid financing materials added by change orders?
A change order can recreate the original cash gap. Price the added scope and document approval before buying more materials whenever the contract and circumstances allow. The field-to-office handoff matters here, too. In an interview, Bob Cardwell, CEO of Cardwell HVAC, said, “…it’s crucial for a contractor to make sure the additional work hours, materials, or change orders have been properly documented so that the office can send out the correct invoice and collect payments without delays.”
Emergency or schedule-critical work may need a different route. Make the exception deliberate and record who authorized it.
Can supplier payment terms reduce the upfront cash needed?
Net terms, staged supplier payments, or supplier financing can help contractors manage the gap between purchasing materials and receiving customer payments. Consolidated purchasing may help secure better terms from strategic suppliers.
Supplier credit should support customer-payment discipline, not replace it. More credit shifts the financing burden; it does not correct an underfunded payment schedule.
How can sales, operations, and accounting coordinate job payments?
For a payment strategy to be effective, information needs to flow along with the project. Each team should be able to confirm what has been approved and whether the related payment has been collected.
Sales
Estimate → Agreement
Pre-job controls
Payment gate → Procurement
Operations
Approved work → Field work
Accounting
Invoice → Payment
The payment gate is the control point. Procurement or field work should not proceed until the required approvals and customer payment are in place.
Where Method CRM fits
Method is a customizable CRM for specialty contractors who use QuickBooks. It can connect the steps that affect a job’s cash flow: estimating, customer approval, deposits, work orders, invoicing, and payment.
Teams can use estimates to define the work, collect deposits, and turn approved estimates into work orders. They can also configure fields and workflows to track procurement status and show whether the required approval and payment have been recorded before a major material order is released.
Field teams can access job details, track time, add billable items, and capture signatures. Customers can use a portal to review documents and pay. Method’s two-way QuickBooks sync keeps customer and transaction information connected, while QuickBooks remains the accounting system.
This gives sales, operations, and accounting a shared view of what has been approved, billed, and paid before the contractor takes on more job costs.
Example: What does a better payment schedule look like on a material-heavy job?
Consider a hypothetical $250,000 project. This example assumes $25,000 of completion costs to show the full cash curve.
| Expected cost | Amount |
| Engineering and preconstruction | $15,000 |
| Equipment and material commitments | $70,000 |
| Fabrication | $20,000 |
| Labor and installation | $45,000 |
| Remaining completion costs | $25,000 |
| Total expected cost | $175,000 |
Scenario A: Payments are weighted toward the back end
The contract calls for 10% at signing, 40% after installation, 40% at substantial completion, and 10% at final completion. The contractor collects $25,000 before committing $105,000 to engineering, equipment, and fabrication, which leaves $80,000 in unfunded commitments. By the time installation is finished, expected costs reach $150,000 against $25,000 collected. That leaves up to $125,000 in costs uncovered by customer payments, depending on when those costs become payable.
Scenario B: Payments follow the expected cost curve
The contract calls for 10% ($25,000) at signing, 32% ($80,000) before procurement, 16% ($40,000) at delivery, 30% ($75,000) after installation, and 12% ($30,000) at final completion. If each payment clears on time, commitments are fully covered at procurement, and before the installation payment there is about $5,000 in expected costs not yet covered by customer payments.
| Decision point | Scenario A cash collected | Scenario B cash collected | Cumulative expected cost |
| Before procurement release | $25,000 | $105,000 | $105,000 |
| Before installation payment | $25,000 | $145,000 | $150,000 |
| Before final completion payment | $125,000 | $220,000 | $175,000 |
The better schedule minimizes the gap between committed costs and customer cash. Final terms still depend on the contract, jurisdiction, retainage, and permissible billing milestones.
What should contractors ask before setting payment dates?
Review every major project stage
- What financial commitments will the company make prior to the completion of this stage?
- When will money actually leave the business?
- How much of the customer payments will the company receive before then?
- What happens if the payment has not arrived from an operational standpoint?
- Who can approve an exception?
What mistakes cause contractors to keep fronting material costs?
Material exposure varies too much for one percentage to fit every project.
The invoice date may have little connection to when the contractor spends money.
The contract contains protection, but the operating workflow ignores it.
A profitable job can still consume substantial working capital.
Additional materials are purchased before added scope enters the payment process.
Operations cannot see whether a financial prerequisite has been met.
When should a contractor still expect to finance part of a job?
Some upfront costs are unavoidable. A general contractor may set payment terms that leave a specialty contractor paying for materials before the next payment arrives. Public projects can have their own payment requirements, and even an established customer may not agree to a deposit that covers every early expense. Contractors should plan for the amount they may need to finance and how long that money could be tied up.
Retainage can add to that gap. On federal fixed-price construction contracts, FAR 52.232-5 lets the contracting officer retain up to 10% of a progress payment if satisfactory progress has not been made. That rule is specific to federal contracts, not a general cap on retainage. Always review your governing agreement and the state and federal rules on deposits and retainage.
The goal is to stop financing jobs by accident
Customers do not need to fund every project dollar before work begins. Contractors do need a deliberate plan for procurement, billing, and collection. Define each commitment, payment date, and response to nonpayment.
When those decisions enter the job workflow, material spending becomes controlled instead of draining working capital unexpectedly.
Frequently asked questions
Estimate what must be paid for materials, fabrication, freight, and other job costs before the next customer payment is expected. Then negotiate a payment schedule that accounts for those cash needs, subject to the contract and applicable rules. Track costs committed separately from payments already due or paid.
Plan for the amount the business will need to finance and how long it may be tied up. Contractors can also negotiate supplier terms, bill for eligible stored materials where the contract permits, or adjust payment milestones. Before accepting the job, compare those options with the cash available to cover the gap.
Yes, but it depends on the contract and the type of work. On commercial projects, material deposits and procurement payments are commonly negotiated into the payment schedule. Residential work can be much more restricted. For example, in California, a home improvement down payment can’t exceed $1,000 or 10% of the contract price, whichever is less. After that, the contractor can’t request or accept payment beyond the value of the work performed or materials delivered. Rules vary by state, so check your state’s home improvement law before setting residential deposit terms.
Material deposits are linked to procurement. Progress payments are related to the progression of work being completed. Depending on an agreement, one can be used alone or together.
Yes. QuickBooks can track materials and other costs by job or project, depending on the product and setup. If your team also needs to coordinate quotes, invoices, and payments outside accounting, Method can give them visibility into that activity alongside QuickBooks data.
