How to Manage Subcontractors as a General Contractor | Reddit & LinkedIn

Short answer

To manage subcontractors well, sign a written sub agreement with a clear scope, collect a certificate of insurance and a signed lien waiver at each payment, schedule trades against your critical path, and tie every sub payment to the draw you collect from the client. Good sub management protects your license, your margin, and your completion date.

Never let a sub start without a signed agreement and a current certificate of insurance.
Collect a lien waiver at every sub payment to protect the owner's title and your reputation.
Schedule trades against the critical path, not first-come-first-served.
Pay subs from the draw you collected for that scope, never ahead of it.
One shared job workspace keeps subs, photos, and payments in sync.

Why do general contractors need written subcontractor agreements?

A written sub agreement is what keeps a missed deadline or a botched scope from becoming your loss. It fixes the price, the scope, the schedule, the insurance requirement, and the lien-waiver rule in one document both sides signed.

Without it, a sub can walk mid-job, bill for work they did not finish, or leave you exposed to a lien from their own unpaid supplier. The agreement is cheap insurance against all three.

How do you track subcontractor insurance and lien waivers?

Keep a current certificate of insurance on file for every active sub, and confirm the coverage limits meet your contract and the owner's requirements. Expired coverage on a job site is a claim waiting to land on your policy.

Collect a signed lien waiver that matches each payment. A conditional waiver before payment and an unconditional waiver after it protects the owner's title and signals to the client that you run a tight shop. ContractShield stores these documents against the job so nothing gets paid without the paper.

How should a general contractor schedule subcontractors?

Schedule against the critical path. Rough-in trades before drywall, drywall before paint, paint before flooring and finish. A sub that shows up before their predecessor scope is ready is a sub standing around billing you for delay.

Share the schedule so every trade sees the same dates. When one milestone slips, the crews downstream need to know same day, not on arrival. A shared job workspace with tasks and a timeline keeps everyone reading the same plan.

How do you pay subcontractors without hurting cash flow?

Tie every sub payment to the client draw for that scope. You collect the milestone from the owner, inspect the sub's completed work, take the lien waiver, then release payment. Paying a sub ahead of the draw you collected is how general contractors run out of cash on a profitable job.

ContractShield lines these up: client milestones on one side, sub scopes on the other, so you can see exactly which draw funds which payment before you release a dollar.

How does software help manage subcontractors?

One shared workspace replaces the group text, the paper folder, and the spreadsheet. Subs get their scope, upload their photos, and see their schedule in the same place you track the client's draws. Documents, insurance, and lien waivers sit on the job, not in your inbox.

As your subs work inside the platform, they also build their own verified profiles, which makes the next job's coordination faster. The tool that runs today's job seeds the crew you reuse on the next one.

Frequently asked questions

Do subcontractors need their own insurance?

Yes. Require every sub to carry their own general liability, and workers' compensation where the state mandates it, and collect a current certificate of insurance before they start. Their coverage protects you if their work or their crew causes a loss.

What is a lien waiver and why collect one from subs?

A lien waiver is a signed release stating a sub or supplier has been paid and gives up the right to lien the property for that amount. Collecting one at each payment protects the owner's title and prevents a sub's unpaid supplier from coming after your client.

How do you handle a subcontractor who misses a deadline?

Fall back on the written agreement. Document the miss, notify the sub in writing, and enforce the schedule and remedy terms you both signed. A shared timeline with dated tasks gives you the record you need if the delay cascades.

Should general contractors pay subs before getting paid?

Generally no. Tie each sub payment to the client draw for that scope: collect the milestone, inspect the work, take the lien waiver, then pay. Paying ahead of your draws is the fastest way to run a profitable job out of cash.

Can one platform manage subs, the client, and payments together?

Yes. ContractShield keeps client milestones, sub scopes, documents, and payments in one job workspace, so you can see which client draw funds which sub payment and never release money you have not collected.

How much does ContractShield cost for contractors?

ContractShield has no seat fee and no per-lead charge. You pay a flat 2% per job, split 1% client and 1% contractor at invoicing, capped at $250 per job. On a $50,000 job that is $250 total, an effective rate near half a percent, because the cap kicks in above roughly $12,500 of job value.
