Every subcontractor you work with, in one place.
Onboard them, approve their paperwork, keep compliance current, schedule their crews, track their labor warranties, collect their lien waivers, pay them — in one system of record.
Free for up to 3 subcontractors. No card, no contract.
The whole relationship, start to finish.
On board, approved, compliant, working, standing behind the work, waivers signed, paid. SubSub handles every stage, so none of it lives in someone's inbox.
Send an invite. They do the rest.
You add a company and an email. They build their own profile from there.
- Nearly 30 trades — framing and concrete through electrical, drywall, tile and paint — plus the cities or ZIP radii they cover.
- Their crews and members, so you schedule a crew, not a company name.
- License, bond, insurance, W-9 and agreement, uploaded from their phone.
Approve them properly, not by eyeballing a PDF.
Filing a certificate isn't reading one. Your requirement sits beside the document, and they stay off jobs until it clears.
- Coverage checked line by line — general liability, aggregate, products and completed operations, auto, employer's liability, umbrella — plus that you're named as additional insured, primary and non-contributory.
- License verified against the state — the WA L&I registry also reports their bond and insurance.
- Accept a short limit when the scope suits it, with a reason on the record.
Compliance that keeps itself current.
Certificates lapse quietly. Someone clear in March may not be in September.
- Expiry tracking on every policy, bond and registration.
- Automatic reminders by email and text, pointing them at their portal.
- Held back until cleared, with a dated record of who approved what, at which limits.
Put the right crew on the right job.
Enter the job once — address, size, schedule, materials, measurements — and pick its trades. The work order writes itself when you assign.
- Matched by trade, distance, availability and rating. Non-compliant subs don't appear.
- Crew-level availability, so you see which crew is actually free.
- One work order per trade, each with its own scope and value.
- They accept or decline from their phone against a deadline you set.
- Change orders, not edits. Found rot on tear-off? A numbered CO the sub accepts, and the revised value is derived — the original work order never changes.
Every labor warranty, tracked by job.
Each sub states how long they stand behind their work. SubSub holds it against every job, so two years on you know whose problem a failure is.
- Warranty term on their profile — 1–10 years or lifetime, set by them.
- Callbacks vs warranty claims — inside 30 days it's a callback, later it's their term.
- Coverage shown on the job — "within 10-year warranty, 8 years remaining", or expired.
- They confirm the return visit, so it lands on their schedule.
A lien waiver before every payment.Scale
Paying your sub doesn't stop the supply house they still owe from filing against the building. The waiver, and the chain below it, is in hand before the money goes.
- Partial or final, conditional or unconditional — asked for against each payment, and unconditional only once the money has gone.
- The right form for the building's state — SubSub's own where the law sets none; in the twelve states that do, the state's form, signed and uploaded.
- Their suppliers are asked too — you see how many have signed and through which date, never their supplier list.
- The payment waits until it's signed, or until you record why you paid without it.
Pay them for the workComing soon
The last piece outside the system. The work order already set the amount when the crew accepted.
- Pay against the work order, at the value agreed, with history per sub.
- Release on completion, once the job is closed and rated.
- Year-end totals already assembled.
Nobody actually knows who's covered.
Certificates sit in somebody's inbox. Registrations lapse without a word. Whether a crew is free is a phone call. So work gets handed out on memory, and the paperwork gets checked after something has already gone wrong.
- All three answered before you assign — free, covered, in range.
- A sub who isn't clear can't be given the job. Not a warning. Blocked.
- The work order writes itself when you pick a crew.

How SubSub works for subcontractorsHandymen and maintenance
Repairs and turns for property managers and owners. They can take you on as a handyman, so you're not asked for a contractor's bond you don't need, and your W-9 is one link away when it's wanted.

Keep scheduling wherever you schedule. The job lands in SubSub with its trades unassigned — which is the queue you open SubSub to clear — and you pick who does the work.

Questions people ask.
What does SubSub do?
SubSub is contractor management software. You onboard subcontractors, review and approve their compliance documents, schedule their crews onto jobs, issue a work order per trade, collect a lien waiver with each payment, and record callbacks, warranty claims and ratings — in one system.
How do I get my subcontractors set up?
Invite them by email, put your application form on your own website — SubSub gives you the code to paste — or, when you meet them in person, have them scan the recruiting QR code in your account (on Scale). They fill in their own company details, trades, crews and coverage area, and upload their documents from their phone. Their login is free, and you review what they send rather than typing it in.
I'm a general contractor. How do I add a subcontractor I meet in person?
Show them your recruiting QR code. In SubSub, press Add, then Subcontractor, and tap They're here with you? — or open Account, then Branding, where the code sits above your application form. They scan it with their phone camera, fill in their own company details, trades and documents, and land on your roster for you to review, with nothing typed off a business card. The recruiting code is part of Scale; on Basic, invite them by email instead.
I'm a subcontractor. How do I connect with a general contractor I meet in person?
Show them your QR code. Open the menu in SubSub and tap My QR code, or find it on your profile. When they scan it, they can ask to work with you, and once you accept they get your compliance pack and can see your schedule and send you jobs. Your account is free.
Do subcontractors pay to use SubSub?
No. Subcontractor logins are free on every plan and do not use a seat. They maintain their own company details, crews, calendars and compliance documents.
What compliance documents does SubSub track?
Certificate of insurance, surety bond, signed subcontractor agreement and IRS Form W-9. Each is reviewed against your requirements, and a subcontractor cannot be assigned to a job until all four are verified.
Does SubSub verify contractor licenses?
Yes. Washington L&I contractor registrations are checked against public state records, which also report the bond and insurance the state has on file, so an uploaded certificate can be cross-checked against it.
Does SubSub track subcontractor labor warranties?
Yes. Each subcontractor states how long they warranty their labor — one to ten years, or lifetime — and SubSub holds that against every job they complete. Defects reported within 30 days of completion are treated as callbacks; later issues are measured against their stated warranty term, so you can see whether a failure is still covered.
How does SubSub handle change orders?
A work order is never edited once accepted. Any change — added scope, deducted scope, or a no-cost change like a date move — is raised as a numbered change order that the other party accepts or declines. Either side can raise one: the general contractor, or the subcontractor who finds hidden conditions on site. The revised value is the original plus every accepted change order, and the work order document shows the full schedule.
Does SubSub handle lien waivers?
Yes, on Scale. Ask for a lien waiver against each payment — partial or final, conditional or unconditional — and the payment waits until it is signed, or until you record why you paid without it. Your subcontractor signs it in SubSub; in the twelve states that set the wording in law, they sign that state's own form and upload it. Anyone they name below them, like a supply house, is asked for theirs too, and you see whether the chain is clear and through which date.
Can jobs come in from my CRM?
On Scale, yes. Scheduled jobs post into SubSub from JobNimbus, from Zapier, Make or n8n, or from anything that can send a webhook, and arrive with their trades waiting for you to assign. Nothing is retyped, and choosing who does the work stays with you.
What does SubSub charge to pay my subcontractors?
Nothing on the first $50,000 you send through SubSub. After that, 0.5% of each payment, and never more than $500 on any one payment. It is added to what you pay, not taken from it, so your subcontractor receives the full amount. Payments you make another way and record in SubSub, like a check, carry no fee. Paying subcontractors through SubSub is part of Scale and is coming soon.
How many text messages come with Scale?
2,500 a month, shared across your account — work orders, invites and updates to tenants. If you go over, texts keep going and are charged automatically on the 1st: $50 for every 5,000 sent that month, or part of 5,000 — so 7,000 texts is $100, 12,000 is $150. You can turn text messages off at any time in Account, and emails still go out. Emergency call-outs are always texted.
Does SubSub handle move-in and move-out inspections?
Yes, for accounts that manage buildings. Walk a unit room by room on a phone or tablet, mark each room fine or needing work, and add photos. Raise one job from the flagged rooms, with the trades suggested from your notes, and send the finished report to the building's owner.
Start with three subcontractors, free.
Invite them, let them build their own profiles, and see it working before you pay.
