Payment Terms That Protect You: Deposits, Progress Schedules, Retention, and Lien Rights

Cash flow is oxygen

Profitable contractors can still go out of business. The mechanism is almost always cash flow: a run of jobs where customer payments arrive slower than payroll, supplier invoices, and vehicle payments need to go out. Your payment terms are the single most important cash-flow lever — far more impactful than bookkeeping discipline or cost-cutting.

Good payment terms do three things: they get deposit money in before material costs go out, they pace progress payments with labor draws, and they leave a small retention at the end so you're motivated to do the punch list.

Deposit sizing

Deposit expectations vary by trade, job size, and market. 2026 industry norms:

Regulatory check: several states cap deposits on residential contracts at 10% or $1,000 (whichever is less), including California. Know your state's rule before accepting a 25% deposit on a $50,000 job — it may not be enforceable.

Progress payment schedule

Progress payments keep the job's cash flow in balance. The schedule should match major labor and material milestones, not calendar intervals. Example schedule for a $72,000 kitchen remodel (8-week project):

Structure it so you're not fronting your own payroll. Cash out should roughly track cash in — not ahead, not behind.

Retention (the final 10%)

The final 5–10% of a contract is traditionally “retention” or “retainage” — held by the customer until punch list is complete and final inspection passes. This exists because:

• It gives you motivation to finish well. The final payment drives punch-list attention.
• It gives the customer recourse. If something genuinely isn't right, they have a small pool of money to negotiate with.
• It's industry-standard — customers often refuse to pay 100% on completion because they've been told to hold back.

5–10% is the norm. Above 10%, you're subsidizing the customer; below 5%, customers feel you don't care about finish quality. The retention should be explicitly timed: “released within 7 days of written punch-list acceptance, not to exceed 30 days from substantial completion.”

Accepted payment methods and processing fees

Your contract should specify accepted methods. 2026 standard options:

• ACH / bank transfer: preferred for large payments — 0–0.8% processing fee, 1–2 day clearance
• Check: still common, especially older homeowners — allow 5 business days to clear before marking paid
• Credit card: accepted but surcharge the 2.9% processing fee back to the customer. On a $20,000 progress payment, absorbing 2.9% is $580 of margin given away
• Financing (Synchrony, Wisetack, GreenSky): useful close tool, but dealer fee is 3–10% depending on term; decide whether you absorb or pass through
• Wire transfer: rare residential; customer pays the $25–$35 wire fee

Handling late payments

Your contract should specify what happens when a payment is late:

• Grace period: typically 5 business days from invoice due date
• Late fee: 1.5% per month (18% APR) is standard and enforceable in most states; some states cap lower
• Stop-work clause: “if a progress payment is more than 10 business days past due, contractor may suspend work until payment is received, and the schedule will extend accordingly.” Protects both parties — customer knows the rule; you get schedule relief when you pause
• Mechanics lien preliminary notice: in states that require it (California, Texas, Oregon, and others), send the pre-lien at the start of the job. This isn't hostile; it's how the mechanics lien system works

Mechanics liens — your last-resort leverage

A mechanics lien is a legal claim against the property for unpaid work. It's your ultimate enforcement mechanism when a customer refuses to pay. Rules vary wildly by state:

• Preliminary notice deadline: some states require a pre-lien notice within 20 days of first work; missing the deadline waives your lien rights on that job
• Lien filing deadline: typically 60–180 days after last work; varies by state
• Foreclosure deadline: after filing, you generally have 90 days to 1 year to foreclose or the lien expires
• Waiver forms: conditional waivers (on payment) and unconditional waivers (payment received) are separate — use conditional until the check clears

Know your state. A compliance calendar of preliminary notices is one of the highest-ROI admin tasks in a contracting business.

Payment terms mistakes

1. Too-small deposit. If your deposit doesn't cover initial material outlay, you're financing the customer's project with your credit line.
2. Calendar-based progress payments. Tie to milestones, not dates. Weather and permits disrupt calendars.
3. No late fee or stop-work clause. Customers pay late when there's no cost to doing so.
4. Skipping preliminary lien notices. Missed deadlines waive your most powerful enforcement tool.
5. Absorbing credit-card fees. On large transactions, 2.9% becomes real money. Pass the surcharge through where legal.
