If you're a contractor — whether in HVAC, electrical, plumbing, roofing, general contracting, or any other trade — you know the cycle too well. You bid the job, buy the materials, do the work, send the invoice, and then... wait. And wait. And wait some more. Meanwhile, you've got payroll to make, materials to buy for the next job, and a truck payment due next week.
The contracting industry has some of the most challenging payment dynamics of any sector. According to Levelset's (now Procore) construction payment surveys, average payment times for contractors routinely stretch beyond 60 days, and write-off rates are among the highest in B2B services. But it doesn't have to be this way.
Why Contractors Get Paid Late
The "Job's Done, Relationship Shifts" Problem
When you're on-site doing the work, you have leverage. The customer needs you to finish the job. Once the work is complete and the system is running, that leverage disappears. The urgency shifts entirely — you're urgent to get paid, but the customer has moved on to their next priority. Your invoice is just another piece of paper in their AP stack.
The Scope and Change Order Trap
Construction and trade work frequently involves changes from the original scope. These changes create ambiguity around the final invoice amount, which gives customers a reason — or excuse — to delay payment while they "review" the charges. Without clear documentation and proactive communication about change orders, these disputes can drag out for months.
The GC-to-Sub Payment Chain
If you're a subcontractor, you're often at the mercy of a payment chain. The property owner pays the GC, the GC pays the subs. If any link in that chain gets slow, you're the one who feels it. "Pay-when-paid" clauses in subcontractor agreements make this problem even worse, essentially making your payment contingent on someone else's payment behavior.
Practical Steps to Protect Your Cash Flow
1. Set Clear Terms Before Work Begins
Every job should have a signed agreement that specifies payment terms, milestones (if applicable), and late payment penalties. This isn't about being adversarial — it's about setting professional expectations. The best contractors we work with use simple, one-page agreements that spell out: total amount, payment schedule, due date, and what happens if payment is late.
2. Invoice Immediately
The clock starts ticking the moment you send the invoice, not the moment you finish the job. Every day between job completion and invoice delivery is a free day for your customer. Invoice the same day the work is done — or better yet, have your office send it while you're still on-site wrapping up.
3. Bill in Milestones for Large Jobs
For jobs over $5,000, consider milestone billing: a deposit upfront, a progress payment at the midpoint, and a final payment on completion. This reduces your exposure on any single invoice and keeps cash flowing throughout the project rather than creating one large receivable at the end.
4. Follow Up Before the Due Date
A pre-due-date reminder is one of the most effective tools in a contractor's AR toolkit. A simple message — "Hey, just a reminder that the invoice for the Main Street job is due next Friday" — puts the payment top of mind and surfaces any issues before they become excuses for delay.
5. Separate the Relationship from the Collection
This is the biggest unlock for most contractors. You're great at building relationships on the job site. You shouldn't have to risk those relationships by also being the person who chases payment. Having a dedicated billing process — whether it's an office manager, a bookkeeper, or an AR management partner like Ledger & Lane — keeps the payment conversation professional and separate from your customer relationship.
The Bottom Line
Contractors do hard, skilled work that deserves to be paid for promptly. The businesses that get paid fastest aren't necessarily the biggest or the most established — they're the ones with the most consistent billing and follow-up process. Build that process, and you'll spend less time chasing money and more time doing the work you love.
