How to Get Paid as a Contractor: 6 Strategies That Work

You finished the job three weeks ago. The invoice is sitting at $8,500. The customer “forgot” to mail the check. Then they stopped answering your calls. Now you're out $4,000 in materials you bought on your credit card, 60 hours of labor, and the mental energy of wondering if you'll ever see the money.

This happens to nearly every contractor at least once. The ones it never happens to again are the ones who built a payment system after getting burned. Here are the six strategies that protect your cash flow — from before you start the job to after you finish.

1. Always Use a Written Contract

A verbal agreement is a lawsuit you haven't filed yet. Every job — even a $500 faucet replacement — needs a written agreement that includes scope of work, total price, payment schedule, timeline, change order policy, and what happens if payment is late.

“If you do work without a contract and/or change order...”

A contractor on r/Contractor — the unfinished sentence says it all. Undocumented work is the primary cause of payment disputes.

Your contract doesn't need to be a 10-page legal document. A clear one-page agreement covering the essentials is enforceable. Read our 12-point estimate checklist for what to include — every item on that list protects your ability to get paid.

2. Collect a Deposit Before Starting

A deposit does two things: it funds your material purchases so you're not financing the customer's project, and it filters out non-serious buyers. A customer who won't put down 10-20% is a customer who may not pay the final 100%.

Check your state's deposit limits. California caps contractor deposits at $1,000 or 10% (whichever is less). Other states have similar limits. Violating the cap can void your contract and expose you to licensing board complaints.

3. Tie Payments to Milestones, Not Dates

A payment schedule that says “$3,000 on April 15” doesn't protect you. What if the work isn't done on April 15? What if it's done on April 10 and the customer waits until the 15th? A milestone schedule eliminates ambiguity.

The 20% holdback at the end gives the customer leverage to ensure you complete the punch list. But it also means 80% of the money is in your account before the final walkthrough. That's the balance. Never let more than 20-30% of the total outstanding at any point.

4. Invoice Immediately at Every Milestone

The #1 collections mistake: waiting until the job is finished to send the invoice. By then, the customer's excitement about the project has faded and the bill feels like a surprise — even though they agreed to it weeks ago.

Send the invoice the same day you complete each milestone. Same day. Not the next morning. Not the weekend. The same day, while the customer can see the completed work and the payment feels connected to visible progress.

“I hate being called in for a service call then get roped into a couple of days of pricing back and forth.”

A plumber on r/Plumbing (8 comments) — the quoting/invoicing cycle eats unpaid hours. Automating it with digital tools saves time AND gets you paid faster.

Digital invoicing with a payment link (credit card or ACH) converts faster than paper invoices. The customer pays in 2 taps from their phone vs finding their checkbook, writing a check, finding a stamp, and mailing it. Every friction point you remove accelerates payment by days.

5. Written Change Orders for Every Addition

This is the rule that saves more money than any other: never do extra work without a signed change order.

“Scope Creep! I'm a one-man crew, so it's not like I'm losing money. What? Your time is your money!!!”

A change order is a one-page document: description of additional work, cost, timeline impact, and signatures from both parties. It takes 5 minutes to write. Without it, you're doing work you can't prove was authorized, for a price the customer never agreed to.

“Can you just add one more outlet while you're here?” Sure — with a change order. “While you're at it, could you paint the trim?” Absolutely — with a change order. Every “while you're at it” is unpaid labor until it's documented.

6. Include a Stop-Work Clause

A stop-work clause in your contract states: if a milestone payment is more than X days late, you have the right to stop work until payment is received. This prevents the nightmare scenario: you keep working while payments fall further behind, finishing an $8,500 job with only the $1,700 deposit collected.

Standard language: “If any payment is more than 7 business days past due, Contractor may suspend work until all outstanding amounts are paid in full. Contractor is not responsible for project delays caused by late payment.”

When Everything Fails: The Mechanics Lien

A mechanics lien is a legal claim against the property where you performed work. It's the nuclear option — and it's remarkably effective.

Most homeowners pay when they receive notice of a lien filing. A lien on the title means they can't sell the house, refinance the mortgage, or take out a home equity loan until it's resolved. That leverage usually ends the standoff.

Critical: in most states, you must send a preliminary notice within 20 days of starting work to preserve your lien rights. If you skip the prelim, you lose the ability to file a lien later. Send it on every job, even when you trust the customer. It's insurance.

“Bidding jobs is part of the process of doing business. It's overhead that is/should be included in your price.”

A homeowner on r/Contractor (166 comments) — and if bidding is overhead, so is collections. Build 2-3% into your pricing for the occasional non-payer so it doesn't destroy your month.
