Contracts and Getting Paid: What Actually Protects You

The Paperwork Nobody Hands You a Manual For

When you’re on somebody else’s payroll, chasing down the money is not your job. Payroll runs on a schedule, invoices go through an accounts payable department, and if a client stiffs the company, that’s a problem for someone in an office you’ve never met. Go independent and all of that becomes yours. The tools are still the easy part. The paperwork that decides whether you actually get paid for using them is the part nobody hands you a manual for.

Short version: A signed contract, not a handshake, is what actually protects you when a job goes sideways. Know what you can legally charge as a deposit in your state, bill in stages instead of waiting until the end, and understand that a mechanics lien secures your claim on a property but doesn’t force payment by itself, you often still need a separate court case to collect. For smaller unpaid balances, small claims court is usually the faster and cheaper route.

Why “We’ve Always Just Shaken On It” Doesn’t Hold Up Anymore

A lot of guys turning a trade skill into a real side business come up through crews and job sites where a verbal agreement and a handshake was how things worked. That’s fine when you’re doing a favor for a buddy. It stops being fine the moment real money and your own liability are on the line.

Without something in writing, a dispute over price, scope, or what was actually included comes down to your word against theirs. Some states legally require a written contract for home improvement work above a certain dollar amount, on top of the practical reason to have one anyway. Check your own state contractor licensing board for what’s required in your state specifically, since this varies and the disclosure requirements (things like mandatory cancellation-rights language) aren’t the same everywhere.

What Actually Belongs In a Client Contract

Keep it simple enough that you’ll actually use it every time, but don’t skip these pieces:

Scope of work. What you’re doing, specifically. “Replace the water heater” is not the same as “replace the water heater, including code-required expansion tank and drain pan if not already present.”

What’s excluded. If something looks like it’s part of the job but isn’t (permit fees, disposal of old materials, drywall repair after an electrical fix), say so in writing.

Total price and payment schedule. Not just the number, but when each payment is due and what triggers it.

Change order process. What happens when the client adds something or changes their mind mid-job. Without this in writing, scope creep becomes unpaid work by default.

Timeline. A start date and a reasonable estimated completion window, not a guarantee, weather and supply delays are real, but an expectation in writing beats no expectation at all.

Your license number, if your trade requires one. Many states require this on contracts and invoices as a matter of law, not just good practice, and it ties directly into what’s covered in the licenses and permits guide.

Where a dispute gets resolved. Doesn’t need to be complicated, just say whether disagreements go to mediation, arbitration, or the local courts.

If you’re working under a subcontractor agreement for a general contractor instead of a homeowner, the shape is different, and the payment terms often aren’t fully in your control. More on that below.

What You Can Actually Ask for Upfront

Deposit rules vary more than most people expect, and getting this wrong isn’t just a client complaint, in some states it’s a licensing violation.

California caps home improvement deposits at 10% of the contract price or $1,000, whichever is less, no exceptions for special-order materials. Maryland allows up to 33%. Nevada caps deposits at 10% of the contract or the cost of any special-order materials, whichever is greater. New York takes a different approach entirely: instead of a percentage cap, it requires pre-completion customer payments to go into a trust or escrow account.

Most states don’t have a statutory cap at all, and the contract governs. Even so, 10% to 33% upfront is the real-world norm, and demanding 50% or more before you’ve turned a wrench is a genuine red flag, both to the client and about your own cash flow. If you need that much money before starting a job to cover materials or mobilization, that’s worth a hard look at how you’re financing your business, which is exactly what the business banking and bookkeeping guide covers.

There’s a leverage reason to keep deposits modest too, beyond legal compliance. Once you’ve collected a big chunk of the money before the job is finished, you’ve given up your best tool for keeping a difficult client cooperative through the rest of the project. Check your specific state contractor licensing board before setting your own deposit policy.

Structuring Payments So You’re Never Working for Free

The fix for most payment disputes isn’t a better contract clause, it’s a better billing rhythm.

Bill in stages tied to verifiable milestones, not a single payment at the end. “Rough-in complete and inspected” is a milestone. “Halfway done” is an opinion, and opinions are what disputes are made of. Take photos at each stage and keep them with the invoice.

Invoice promptly. The longer the gap between finishing a stage of work and asking to be paid for it, the easier it is for the client’s memory of what was actually agreed to start drifting.

On payment terms, due on receipt or net 15 is the norm for direct-to-consumer trade work, not net 30. Net 30 makes sense between two businesses running on their own accounts-payable cycles. A homeowner doesn’t have that cycle, so there’s no real reason to extend them one.

Put a late payment term in the contract itself, before you ever need it. A late fee or interest rate that both sides agreed to in writing holds up far better, with a client and in front of a judge if it ever gets there, than one you try to introduce after the fact. Usury laws cap how high that rate can legally go, and the cap is different state to state, so check yours before picking a number.

Lien Waivers: Don’t Sign Away Your Leverage Before You’ve Been Paid

A lien waiver is a document where you give up your right to file a mechanics lien for specific work or a specific payment. It comes in four combinations, built from two separate choices:

Conditional versus unconditional. A conditional waiver only takes effect once the payment actually clears your bank. An unconditional waiver takes effect the moment you sign it, whether or not the money ever shows up.

Progress versus final. A progress waiver covers only the payment period it names. A final waiver covers the entire remaining balance on the job, including any retention being held back.

The mistake that costs people real money: signing an unconditional waiver before the check has actually cleared. If the payment bounces, gets stopped, or never arrives, you’ve already given up your lien rights for that amount, with nothing to show for it. The rule that keeps you safe is simple, sign conditional waivers before payment, and only sign an unconditional waiver once the money is confirmed in your account, not just received.

Some states require specific statutory waiver language and won’t recognize a generic template. If you’re being asked to sign one, or asking a client to sign one for a large final payment, check whether your state is one of them before using a boilerplate form.

The Mechanics Lien: What It Actually Does (and Doesn’t Do)

You may have seen posts from other guys in the trades claiming something like “just file a lien and the county forces them to pay you.” That’s not quite right, and believing it can cost you time you don’t have.

A mechanics lien is a legal claim against the property itself for unpaid labor or materials. What it actually does is create real leverage, a property with a lien attached usually can’t be sold or refinanced cleanly until it’s resolved, which motivates a lot of owners to settle. What it doesn’t do is hand you a check. If it goes unpaid, you typically still have to file a separate lawsuit within a set window to enforce, or foreclose on, the lien, or your claim expires.

Deadlines vary enormously by state, roughly 45 days in Hawaii to 240 days in New York, with most states landing somewhere between 60 and 120 days after your last day of substantive work on the project. Many states also require a separate preliminary notice earlier in the job, often due within 20 to 45 days of when you first started, and in states like California, Michigan, Florida, and Minnesota, missing that notice can wipe out your lien rights before you’ve even finished the work.

One detail that trips people up: warranty callbacks, punch-list touch-ups, and equipment pickup generally don’t reset or extend the clock. Courts have consistently held that the deadline runs from your last day of real, substantive labor or material delivery, not from whatever you did last on the property. Liens also only apply to private property, work on federal or public projects uses a different tool entirely (a payment bond claim), not a lien.

Because the exact numbers shift by state and by whether you’re a general contractor, sub, or supplier, Levelset keeps a free, current state-by-state guide to lien deadlines and preliminary notice rules. It’s a legitimate resource, but it’s not a substitute for an attorney if there’s real money on the line and the timeline is close.

Small Claims Court: Often the Better Move for Smaller Amounts

A lien and small claims court are not the same tool doing the same job, and a lien can’t be enforced from inside small claims court at all, it’s a different court, a different process.

For smaller unpaid balances, suing directly in small claims is often faster, cheaper, and doesn’t require hiring a lawyer. Limits vary by state, and a few states set a lower cap for businesses than for individuals. California, for example, allows individuals to sue for up to $12,500 but caps business claimants (which includes most independent contractors) at $6,250. New York allows $10,000 for individuals and $5,000 for businesses. These numbers do get raised periodically, so verify your state’s current limit before deciding.

The practical takeaway: if your unpaid balance is small enough to fall under your state’s small claims limit, it’s often simpler to skip the lien process’ notice and deadline machinery entirely and go straight to small claims. Save the lien route for balances that are large enough, and disputes that are stubborn enough, to justify the extra paperwork and the sharper deadlines.

If You’re Subcontracting Instead of Contracting Directly

Everything above assumes you’re the one holding the contract with the property owner. If you’re working as a sub for a general contractor instead, payment usually flows differently.

Know whether your subcontract has a pay-when-paid or pay-if-paid clause before you sign it. A pay-when-paid clause just delays your payment until the GC gets paid by the owner. A pay-if-paid clause can eliminate your payment entirely if the GC never gets paid, shifting that risk onto you. These sound similar and are not.

Your own lien and preliminary notice rights still exist independently of what the GC’s contract with the property owner says. Track your own deadlines regardless of what you’re told about payment timing, since nobody else on that job is looking out for them on your behalf.

What This Guide Doesn’t Cover

This one is strictly about the contract and payment side. General liability coverage, workers’ comp, and the different kinds of bonds (license bonds, performance bonds, bid bonds) are their own subject, covered in full in the liability insurance and bonding guide. If you haven’t set up the business itself yet, that starting point is in the pillar guide on going independent, and if your contracts and invoices still need a proper business address on them, that’s covered in the business address and registered agent guide.

If you’re still deciding whether to formalize a side hustle like handyman work or mobile mechanic work into something more, this is the paperwork that starts mattering the moment real client money is involved, not just at the point you form an LLC.

Frequently Asked Questions

Not always, but you should have one anyway. Some states legally require a written contract for home improvement work above a certain dollar amount, and even where it’s not required, a written contract is the only real protection you have if a client disputes the price, the scope, or what was included.

It depends on your state. Some states cap deposits by law (California limits it to 10% of the contract price or $1,000, whichever is less; Maryland allows up to 33%). Most states have no statutory cap, but 10-33% is the industry norm, and asking for 50% or more upfront is generally considered a red flag. Check your state contractor licensing board before setting your policy.

A conditional waiver only takes effect once the payment actually clears your bank. An unconditional waiver takes effect the moment you sign it, whether or not the payment ever arrives. Never sign an unconditional waiver until the money is confirmed in your account.

It varies a lot by state, generally somewhere between 45 and 240 days after your last day of substantive work, with most states landing between 60 and 120 days. Many states also require a separate preliminary notice earlier in the job, sometimes within 20 to 45 days of starting work. Check your state’s specific deadlines before assuming you have time.

They’re not interchangeable. A lien secures a claim against the property but usually still requires a separate court case to actually collect. For smaller unpaid balances under your state’s small claims limit, suing directly in small claims court is often faster and cheaper, and doesn’t require a lawyer.

It’s a clause in a subcontractor agreement that ties your payment to when the general contractor gets paid by the property owner. A “pay-when-paid” clause usually just delays your payment; a “pay-if-paid” clause can eliminate it entirely if the GC never gets paid. Know which one is in your contract before you sign it.
