A contractor on a construction job gets paid through a scheduled series of payments tied to the physical progress of the work, not in one lump sum. A typical sequence runs: a modest deposit at signing, progress payments released as the contractor finishes defined milestones (foundation, framing, rough-ins, drywall, finishes), a small percentage held back as retainage, and a final payment once the punch list is complete and the required paperwork is in hand. The exact amounts, triggers, and timing come from the contract, and the mechanics shift when a construction lender is funding the job rather than the owner writing checks directly.
The Payment Sequence from Start to Finish
Most residential and small commercial jobs follow the same arc. The contractor collects a deposit, bills for progress at defined points, and receives a final payment after the owner accepts the completed work.
The Deposit
The deposit secures the contractor’s schedule and funds the first round of materials and mobilization. A handful of states cap the amount by statute, often at 10% of the contract price or $1,000, whichever is less. Even where no cap applies, keeping the deposit modest protects both sides: the contractor gets enough to order long-lead items like custom windows, and the owner limits exposure if the relationship breaks down early.
Progress Payments
The bulk of the contract price moves through progress payments. Each one is tied to a milestone written into the contract, and each payment should match the percentage of work actually in place rather than the calendar. Many contracts also require the relevant building code inspection to pass before the next payment is released, which gives the owner an independent check on quality beyond what they can judge themselves.
Retainage
Retainage is a portion of each progress payment the owner holds back until the whole job is finished, typically 5% to 10%, with many states capping it by statute. The withheld money creates a reason for the contractor to come back and close out the small items: touch-up paint, hardware adjustments, scuffs from moving equipment. Retainage is usually released 30 to 60 days after the owner accepts the completed work.
The Final Payment
The final payment, including the released retainage, is due once the punch list is complete and the contractor has delivered the final paperwork, most importantly a final lien waiver covering all remaining work and materials.
How the Contract Type Shapes the Payments
Before the first invoice goes out, the contract type determines how the total price is calculated and who absorbs the cost of surprises.
Fixed-Price (Lump-Sum)
A fixed-price contract sets a single total covering labor, materials, subcontractors, and the contractor’s profit. The owner knows the price before work begins, which makes budgeting straightforward. The contractor carries the risk of overruns, so bids usually include a cushion for that risk. Progress payments on a fixed-price job are a defined dollar amount or percentage at each milestone.
Cost-Plus
Cost-plus flips the risk. The owner pays all actual project costs and adds a profit margin on top, commonly 10% to 20% of total costs or a flat management fee. Every invoice is backed by receipts, and the final price is not known until the job wraps. Some cost-plus agreements include a guaranteed maximum price that caps the owner’s exposure while letting the contractor bill actual costs up to that ceiling.
Time-and-Materials
When the scope is not clear at the start, time-and-materials billing lets the work proceed without a locked total. The owner pays an hourly labor rate plus the actual cost of supplies. This works for renovations where hidden conditions (rotted framing, outdated wiring) only appear once walls come open. The owner has to monitor logged hours and submitted receipts to keep costs from drifting.
Escalation Clauses
Volatile material prices have made escalation clauses common across all contract types. The clause defines a trigger, often a 5% rise above the signing-date price for a specific material, and allows the contract price to adjust rather than forcing either side to absorb the swing or reopen the deal. If the job involves steel, copper, or engineered lumber, an escalation clause is worth insisting on.
Paperwork That Has to Clear Before Money Moves
Payment does not run on the work alone. Specific documents have to be in order, and a missing piece can hold up a scheduled payment.
The Invoice
A formal invoice is the contractor’s official request for payment. It should spell out the work completed, the dates it was performed, and how the billed amount ties back to the milestones in the contract. A vague line like “Phase 2 work — $18,000” invites disputes. A good invoice cross-references the contract and includes enough detail that the owner or lender can verify the amount without a follow-up call.
Lien Waivers
A lien waiver is a signed document in which the contractor, and ideally every subcontractor and supplier, confirms payment through a specific date and gives up the right to file a legal claim against the property for that amount. Collecting these with every progress payment is one of the single most important things an owner does. Without them, a subcontractor who was not paid by the general contractor can file a mechanic’s lien on the property even if the owner paid the GC in full. There are two forms: a progress payment waiver covering work through a specific date, and a final payment waiver that releases all remaining claims at completion.
Proof of Insurance
Before the first payment goes out, the owner should have a current certificate of insurance from the contractor on file. At a minimum that means general liability coverage and, in nearly every state, workers’ compensation for the contractor’s employees. If an uninsured worker is injured on the property, the owner can face personal liability. Certificates expire, so on longer jobs it is reasonable to request updated proof at major milestones.
Tax Documents for Independent Contractors
If an owner hires an independent contractor directly rather than through a company that issues W-2s, the IRS requires a completed Form W-9 before the first payment. The W-9 captures the contractor’s name and taxpayer identification number for year-end reporting. For payments made in 2026, a Form 1099-NEC must be filed with the IRS if an independent contractor is paid $2,000 or more during the calendar year.1Internal Revenue Service. 2026 Publication 1099 (Draft) That threshold was raised from $600 by the One Big Beautiful Bill Act, so older guides citing $600 are out of date. Collect the W-9 at signing rather than chasing it down in January.2Internal Revenue Service. Forms and Associated Taxes for Independent Contractors
When a Construction Loan Pays the Contractor
On a financed project, the owner does not write checks directly to the contractor. The lender controls the funds and releases them through a draw process.
After a milestone is finished, the general contractor submits a draw request with supporting documentation: invoices, lien waivers, and proof of completed work. The lender sends an inspector to verify the physical progress matches what is being billed. If the inspection confirms the work meets contract specifications, the lender releases that draw. If it falls short, funding pauses until the deficiency is corrected.
This protects the owner from paying for incomplete work, but it also slows the cycle. Turnaround from draw submission to disbursement varies by lender, from as fast as 48 hours to several weeks. Delayed inspections are one of the biggest causes of cash flow problems on financed jobs. When a contractor is complaining about slow pay on a loan-funded project, the bottleneck is usually the lender’s inspection schedule rather than the owner.
How the Money Actually Moves
The transfer method matters less than whether it clears on time, but each option has trade-offs.
Paper checks remain common, especially among owners paying out of pocket. The canceled check is a built-in receipt and there are no transaction fees. The drawback is speed: a check received Friday may not clear until the following week, and banks sometimes place extended holds on large amounts, which pinches the contractor’s ability to pay subs and suppliers.
Wire transfers move money bank-to-bank, usually the same business day for domestic transfers, at a cost of roughly $25 to $30 per outgoing wire at most banks. The speed makes wires practical for large progress payments. Digital business payment platforms offer comparable speed with automated tracking and confirmations, and tend to be more convenient for smaller amounts or change-order settlements.
On high-value projects, some parties use an escrow arrangement where a neutral third party holds the project funds and releases them only when both sides confirm a milestone is complete. Escrow adds cost and processing time, so it is uncommon on routine renovations and tends to appear on large custom builds or commercial jobs.
If a Payment Is Late
Late payment is the most common source of conflict on construction jobs, and the law gives contractors real leverage when owners do not pay on time.
Prompt Payment Statutes
The federal Prompt Payment Act requires government agencies to pay automatic interest on late invoices, calculated from the day after the required payment date through the date payment is actually made.3Office of the Law Revision Counsel. United States Code Title 31 – 3902 Interest Penalties That statute covers federal government work rather than private residential projects. On the private side, roughly 35 states have their own prompt payment laws. State interest penalties for late payments range from around 5% per year up to 2% per month (roughly 24% annually) in states with stronger protections. Many of these statutes also award attorney’s fees to the party that prevails in a collection action, which shifts the litigation risk back to whoever caused the delay.
Mechanic’s Liens
The mechanic’s lien is the contractor’s most powerful collection tool. It attaches a legal claim to the property itself, not just to the person who owes the money, and it clouds the title so the owner typically cannot sell or refinance until the lien is resolved. Every state has a mechanic’s lien statute, with procedures and deadlines that vary significantly.
The general process has three steps. First, most states require the contractor or subcontractor to send a preliminary notice to the owner within a set window after starting work. Second, if payment is not received, the contractor files a lien affidavit with the county clerk. Third, the contractor must enforce the lien by filing a lawsuit within a statutory deadline, which ranges from a few months to a couple of years depending on the state. Missing any of these deadlines can void the lien entirely. For owners, the best defense against a lien from an unpaid subcontractor is collecting lien waivers with every progress payment, which is why that step matters so much.
Dispute Resolution Written into the Contract
When a payment dispute cannot be settled with a phone call, the resolution path usually tracks what the contract says. Many well-drafted construction contracts require mediation before either side can file suit, and some require binding arbitration after that. Arbitration moves faster than court and involves fewer procedural steps, but arbitration awards are extremely difficult to appeal. Litigation is the fallback when the contract does not specify an alternative, and court cases can drag on for years with legal costs that often dwarf the amount in dispute. If the contract does not include a mediation or arbitration clause, that is worth raising before signing.
