Invoicing and Getting Paid: How Contractors Stop Chasing Money

Slow payment isn’t a customer problem — it’s a systems problem. Contractors who get paid fast do the same few things on every job, and none of them involve awkward phone calls. Here’s the system.

Set payment structure before the job starts

Payment terms belong in the estimate, not the final invoice. Standard structures:

Small jobs (under ~$2,000): payment due on completion, day of. Say it up front: “I’ll collect when we do the final walkthrough.”
Mid-size jobs: deposit + balance on completion. Deposits of 10–30% are typical — check your state’s limits (California caps home-improvement deposits at $1,000 or 10%, whichever is less; many states have no cap).
Larger projects: deposit + progress payments tied to milestones, not dates (“after rough-in inspection,” not “on the 15th”). Never let work get more than one payment ahead of money received.

The rule underneath all of it: the work and the money stay close together. Most non-payment disasters started as “I’ll invoice for all of it at the end.”

Invoice same-day, every time

An invoice sent the evening the job finishes gets paid dramatically faster than one sent “when I get to paperwork Sunday.” Whatever software you use, build the habit: final walkthrough → invoice sent from the driveway.

What a clean invoice includes:

Clear line items matching the estimate (plus any signed change orders)
Due date (“Due on receipt” or “Net 7” — never Net 30 for residential work)
A payment button. One-click card/ACH payment is the single biggest speed upgrade.
License number and business info

Cards, ACH, and who eats the fee

Cards: ~2.9–3.5% per transaction. On a $10,000 invoice that’s $300+ — real money.
ACH/bank transfer: typically 1% or a flat fee, often capped. The right default for big invoices.
Checks: fine, slow, and they bounce; deposit same day.
Cash-discount / surcharge programs exist, but rules vary by state and card network — the simpler move is pricing fees into your rates and offering ACH as the low-fee path: “Card is fine; bank transfer saves the processing fee.”

Never refuse convenient payment on a big invoice to save 1%. Speed beats fee.

The follow-up sequence (automate it)

Most late payments are forgetfulness, not malice. A polite automatic sequence fixes 90% of them:

Due date: friendly reminder with the payment link.
+3 days: “Just making sure this didn’t get buried — link below.”
+7 days: a phone call. Human, brief: “Wanted to check the invoice reached you — any issue with the work I should know about?” (This also surfaces real disputes early.)
+14 days: written notice that late terms apply, if your contract has them (e.g., 1.5%/month where legal).

Most FSM software sends steps 1–2 automatically. Turn it on and the awkwardness disappears — “the system sends those.”

Your leverage, and when to use it

Preliminary notice / lien rights. In many states, protecting lien rights on larger jobs requires sending a notice near the start of work — not when things go wrong. Know your state’s rules before you need them; on commercial and new-construction work, treat notices as routine paperwork, not aggression.
Stop-work. On progress-payment jobs, a missed milestone payment pauses the schedule. Enforce it early and politely; contractors get buried by continuing to work on hope.
Small claims court handles most residential disputes cheaply. Your organized paper trail (contract, change orders, photos, invoices, reminders) wins these.

Watch your real number: days-to-paid

Track the average days between invoice sent and money received. Under 7 is healthy for residential service work. If it’s creeping past 14, the fix is almost always upstream — terms not set before the job, invoices sent late, or no payment link.
