Quick answer: The average contractor spends about 130 hours a year — more than three full work weeks — chasing money they've already earned. The root cause is structural, not personal: payment terms get agreed verbally, invoices arrive disconnected from the original proposal, and nothing is collected at the moment of highest commitment (signing). Fixing the structure — deposit collected at signature, a payment schedule both sides agreed to in the contract, and invoices that tie line-by-line back to the signed scope — eliminates most of the chase.
How bad is it, really?
The construction industry has the worst payment timeline of any major sector:
- Average construction DSO (days sales outstanding) is ~83 days — versus roughly 60 days across all industries (K38 Consulting).
- Only 5% of subcontractors report being paid on time (K38).
- Invoices that age past 90 days collect at about 70 cents on the dollar (K38). Slow payment isn't just annoying — it's a discount you never agreed to give.
- Industry-wide, payment delays cost US construction an estimated $280 billion in 2024 (PBMares / For Construction Pros).
- And contractors quietly pass it on: GCs and subs bake an average 5.3% overhead into bids just to finance slow payments (K38).
One construction company freed up $1.37 million in working capital by cutting DSO just 10 days (K38). You don't need to be a million-dollar shop for the same math to matter — on $800K of annual revenue, 10 days of DSO is roughly $22,000 that's sitting in someone else's bank account instead of yours.
Why chasing harder doesn't work
Most advice about late payments boils down to "invoice promptly and follow up." Fine — but it treats the symptom. By the time you're writing the third reminder email, the problem already happened, weeks earlier, in three specific places:
1. The terms were never really agreed. A line at the bottom of an estimate ("50% deposit, balance on completion") that nobody discussed isn't an agreement — it's a suggestion. When payment terms live inside the signed contract as a schedule the customer explicitly reviewed, "when do I pay?" was answered before the job started.
2. Nothing was collected at the moment of commitment. The single highest-leverage change a contractor can make: collect the deposit at signing, in the same sitting, as part of the same flow. Signature without payment is a promise; signature with payment is a customer with skin in the game. Every day between "we'd love to move forward" and money in hand is a day for budgets to shift and cold feet to set in.
3. The invoice doesn't match the paperwork. When an invoice shows up weeks later with numbers that don't visibly tie back to the proposal — different line items, different groupings, a change order folded in without explanation — the customer does the rational thing: they stall and ask questions. More than 1 in 3 contractors say payments get delayed by disputes over the work (Levelset), and many of those "disputes" are really just documents that don't reconcile.
The structure that gets you paid
Here's the payment flow used by shops that don't chase:
- Proposal states the payment schedule explicitly — deposit %, milestone draws, final payment — as numbered terms in the document the customer signs. Not boilerplate; the actual schedule for this job.
- E-sign and deposit happen together. Customer signs on their phone, pays the deposit by card or bank transfer in the same flow. E-signature alone cuts time-to-signed-contract by 41% (DocuSign); pairing it with payment collapses your first DSO window from weeks to minutes.
- Milestone invoices reference the agreed schedule ("Payment 2 of 3 per agreed schedule") and tie line-by-line to the signed proposal and any signed change orders. Nothing to question, nothing to reconcile.
- Changes go through signed change orders before the work happens — so the final invoice never contains a surprise, which is what most end-of-job payment fights are actually about.
None of this requires being aggressive with customers. It's the opposite: clear terms and clean paperwork are easier to pay against, and customers respect a contractor who runs the money side like a business.
This flow is the core of what Sharp & Hired automates — the proposal carries the payment schedule, the customer signs and pays the deposit in one mobile flow, and every invoice ties back to the signed documents — but the structure works no matter what tools you use. The point is to stop chasing and start collecting on terms both sides already agreed to.
FAQ
What deposit should a contractor collect at signing? Common practice is 10–33% depending on job size and state law (some states cap home-improvement deposits — check yours). The amount matters less than the timing: collect it at signature, not "before we start."
Is it unprofessional to ask for payment at signing? No — it's standard for serious shops. Customers who balk at any deposit are signaling risk you'd rather discover before demo day.
How do I bring up payment terms without souring the deal? Put them in the proposal as a clear schedule and walk through them in 30 seconds at presentation. Customers stall on ambiguity, not on clarity.
What about jobs paid by insurance? Insurance and lender-paid work follows the carrier's or lender's disbursement timeline, but the same principle applies: document the payment source and schedule in the signed contract so everyone knows where the money comes from and when.
