Trade Cash-Flow & Contract Rules · Concrete & Flatwork Contracting
Managing concrete & flatwork contracting partial payments and progress draws requires tying each draw to a physical milestone (40% mobilization deposit of $1866, mid-job rough-in/prep draw, and completion balance of $2798) and issuing a running-balance receipt whenever a check is short.
Key Takeaways
- Upfront protection: Collect a 40% deposit ($1,866) so you never finance $1,950 of concrete & flatwork contracting materials out of pocket.
- Enforce Net-Due-on-Completion terms with a stated 1.5%/month (18% APR) contractual late fee and state Preliminary Notice rights.
- Document completion with timestamped job photos, signed walkthrough approval, and an itemized invoice referencing ACI 302/318 slab thickness, PSI mix design, rebar grid & control-joint spacing.
“Every person who performs labor upon or furnishes material to be used in the construction, alteration, or repair of any building or structure shall have a lien upon the property for the work or labor done or materials furnished.”
Concrete Partial Payment & Milestone Billing Guide for Concrete contractors (2026)
Short answer: Handling a concrete partial payment requires separating planned milestone draws from an unexpected short-pay: on multi-day concrete jobs (a driveway or a patio), schedule a 40% upfront draw for Ready-mix 4,000 PSI concrete, rebar, wire mesh & forms (Line 22) (~$1950) followed by physical completion milestones per sq ft poured; if a customer unexpectedly short-pays your final invoice, credit the partial payment on the same invoice number and send an immediate Balance Due Statement.

What is the difference between planned concrete progress draws and an unexpected short-pay?
Eliminating unpaid extras and billing friction across solo concrete requires distinguishing two completely different scenarios that both involve a concrete partial payment:
- Planned Milestone Progress Billing: When a concrete contractor takes on a multi-day project like a patio or a garage slab (18+ hours at $110/hr and ~$1950 in materials), splitting the contract into a 40% deposit and physical stage draws prevents you from financing the client’s property out of your own pocket.
- Unplanned Short-Pay at Completion: You finish a driveway, present the final invoice for $10194.80, and the customer pays only part of the balance—often citing cash-flow timing or questioning a line item like Forming or forgetting to bill the $125 trip/setup charge, unrecorded Cure and sealer, and Ready-mix 4,000 PSI concrete, rebar, wire mesh & forms (Line 22).

How should a concrete contractor tie progress payments to physical sq ft poured milestones?
Never tie a concrete partial payment schedule on a patio to vague calendar dates or “50% halfway done”—because a homeowner and a concrete contractor never judge “halfway” the same way. Anchor every draw to a verifiable physical event governed by ACI 302/318 slab thickness, PSI mix design, rebar grid & control-joint spacing:
| Concrete Operational Benchmark — Milestone draw structure | Field Standard for Solo Concrete contractors |
|---|---|
| Primary Pricing Unit & Rate | $8.5–$16 per sq ft poured ($110/hr + $125 trip fee) |
| Upfront Deposit Benchmark | 40% deposit on multi-day/material jobs (40% upfront deposit on multi-day or material-staged concrete jobs (100% on completion for single-visit service calls)) |
| Wholesale Material Markup | 22% markup on Ready-mix 4,000 PSI concrete, rebar, wire mesh & forms (Line 22) (~$1950 sample materials) |
| Common Scope Additions | Rebar or mesh, Concrete delivered, and expedited concrete scheduling |
| Code & Permit Standard | ACI 302/318 slab thickness, PSI mix design, rebar grid & control-joint spacing (typical permit allowance: $180) |
| Key Deductible Expenses | Ready-mix 4,000 PSI concrete, rebar, wire mesh & forms (Line 22); Power trowels, plate compactors, concrete saws & bull floats (Line 18) |
| Vehicle & Route Deduction | Dump trailer & crew truck mileage to batch plants and job sites (Line 9) |
| Frequent Billing Gotcha | forgetting to bill the $125 trip/setup charge, unrecorded Cure and sealer, and Ready-mix 4,000 PSI concrete, rebar, wire mesh & forms (Line 22) |
- Draw 1 — 40% Booking & Material Staging: Due upon estimate approval to order Ready-mix 4,000 PSI concrete, rebar, wire mesh & forms (Line 22) and file any $180 permit paperwork.
- Draw 2 — Prep / Rough-In Milestone (Multi-Day Concrete Jobs): Due when Excavation and base prep and Forming are completed on site.
- Draw 3 — Substantial Completion & Walkthrough: Due the moment Rebar or mesh is finished and inspected under ACI 302/318 slab thickness, PSI mix design, rebar grid & control-joint spacing.
How do you record a partial payment on a concrete invoice without losing the balance trail?
Whether a customer is paying Draw #2 on a garage slab or making a partial payment toward a completed a driveway ticket, keep every dollar attached to the original sequential invoice number:
| Concrete Scope Line (progress & balance ledger) | Quantity & Unit (sq ft poured) | Unit Rate (USD) | Extended Line Total |
|---|---|---|---|
| Excavation and base prep (progress & balance ledger) | 47 sq ft | $125.01 | $5875.47 |
| Forming | 3 linear ft | $181.74 | $545.22 |
| Rebar or mesh | 3 sq ft | $106.10 | $318.30 |
| Concrete delivered | 5 cubic yard | $162.83 | $814.15 |
| Pump (if access requires) | 5 flat | $87.19 | $435.95 |
| Finish — broom, trowel, stamped | 8 sq ft | $143.92 | $1151.36 |
| Control joint cutting | 7 linear ft | $68.28 | $477.96 |
| Cure and sealer | 10 sq ft | $125.01 | $1250.10 |
| Concrete Ticket Subtotal (progress & balance ledger) | Billed per sq ft poured | $110/hr benchmark | $10868.51 |
When the client pays 60% of this concrete ticket today, log the exact payment date and method on the invoice, display Less Partial Payment Received, and email/text the updated PDF showing the exact Remaining Balance Due and due date.
Why must a concrete contractor watch out for “Paid in Full” memo lines on partial checks?
Under Uniform Commercial Code § 3-311 (Accord and Satisfaction) and state contract rules referenced in OSHA Construction & Field Trade Operations Portal, depositing a short-paid check can be a costly legal trap for a concrete contractor:
- The “Paid in Full” Trap on Disputed Concrete Bills: If a client disputes your charge for Rebar or mesh or forgetting to bill the $125 trip/setup charge, unrecorded Cure and sealer, and Ready-mix 4,000 PSI concrete, rebar, wire mesh & forms (Line 22) and hands you a partial check with “Paid in Full” written in the memo line, cashing that check in many states legally extinguishes your right to collect the remaining balance!
- Safe Handling Protocol: If the partial payment is simply an agreed two-part payment plan on a driveway, get a quick text or email reply from the customer confirming the remaining dollar balance and payment date before depositing. If there is a dispute and the check says “Paid in Full,” demand a clean replacement payment or written settlement agreement first.
How do lien waivers and Schedule C taxes work on concrete partial payments?
Protect both your legal collection rights and your tax ledger whenever you accept a concrete partial payment:
- Use Only a Conditional Partial Lien Waiver: If a general contractor or property manager requests a lien waiver for a progress draw on a patio, sign only a Conditional Waiver and Release on Progress Payment limited to the exact dollar amount received—never an Unconditional Final Waiver.
- Cash-Basis Tax Timing (IRS Pub 334): Report each partial payment in the tax year the funds are received, while deducting Ready-mix 4,000 PSI concrete, rebar, wire mesh & forms (Line 22), Power trowels, plate compactors, concrete saws & bull floats (Line 18), and Dump trailer & crew truck mileage to batch plants and job sites (Line 9) in the year you pay for them.
Why do independent concrete contractors use Keel for partial payments and expense tracking?
When a concrete contractor is handling concrete partial payment between service calls at $110/hr, paperwork has to take seconds, not hours. Keel lets solo concrete contractors issue crisp PDF estimates and invoices on iPhone, photograph vendor receipts (Power trowels, plate compactors, concrete saws & bull floats (Line 18)), and track mileage with no bank connection. Free to download on the App Store.
How do permit fees ($180) and code rules affect concrete partial payments?
Because concrete work involving concrete partial payments is governed by ACI 302/318 slab thickness, PSI mix design, rebar grid & control-joint spacing and deducts Ready-mix 4,000 PSI concrete, rebar, wire mesh & forms (Line 22), keeping dated digital copies of every invoice and supplier receipt under OSHA Construction & Field Trade Operations Portal prevents cash-flow surprises when quarterly estimated taxes fall due.
Frequently asked questions
Should a concrete contractor accept a partial payment if a homeowner cannot pay the full concrete invoice today?
Yes—taking 50% to 75% of the balance on site immediately reduces your exposure on a driveway while you are still in the driveway. Log the partial payment on your concrete invoice, get a written text or signed note confirming the exact date the remainder will be paid, and calendar your state’s mechanics’ lien deadline.
Can cashing a partial check marked “Paid in Full” cancel the rest of my concrete invoice?
Yes. Under UCC § 3-311 in most states, depositing a check marked “Paid in Full” or “Full Settlement” on a disputed concrete bill can legally bar you from collecting the remaining balance—even if you cross out the memo line before depositing the check. Keeping your sequential concrete client invoices, dated supply-house receipts, and signed scope approvals organized by job address ensures you can verify every figure during a customer walkthrough or tax review.
What lien waiver should a concrete contractor sign when collecting a progress draw?
Sign only a “Conditional Waiver and Release on Progress Payment” that specifies the exact partial dollar amount and through-date for Excavation and base prep. Never sign an Unconditional Final Lien Waiver until 100% of the concrete contract and change orders have cleared your bank. Keeping your sequential concrete client invoices, dated supply-house receipts, and signed scope approvals organized by job address ensures you can verify every figure during a customer walkthrough or tax review.
How do I structure milestone payments on a larger concrete job like a patio?
Start with a 40% deposit to fund Ready-mix 4,000 PSI concrete, rebar, wire mesh & forms (Line 22) (~$1950) and $180 permit prep, add a mid-job milestone tied to physical completion of Excavation and base prep, and collect the final balance upon walkthrough under ACI 302/318 slab thickness, PSI mix design, rebar grid & control-joint spacing.
Does my 1-year concrete workmanship warranty apply if the customer only made a partial payment?
State clearly in your concrete estimate and invoice terms that your workmanship warranty and any non-statutory coverage under ACI 302/318 slab thickness, PSI mix design, rebar grid & control-joint spacing take effect only after 100% of the contract balance is paid in full. Keeping your sequential concrete client invoices, dated supply-house receipts, and signed scope approvals organized by job address ensures you can verify every figure during a customer walkthrough or tax review.
