Subcontractor Management Software
Bid work out to subs, track their insurance and rates, and run RFIs, submittals, and change orders through one hub — with no login required on their end.
Subcontractor coordination is mostly a document problem. The bid went out in an email, the certificate of insurance is in a folder someone can't find, and the change order was agreed on the phone.
SiteAnchor puts the whole exchange on the job. Subs work through a no-login portal reached by a private link, which matters because the reason subs don't adopt your software is that they aren't going to create an account to do it.
What it does
Bid out by trade or saved group
- Invite subs individually, by trade, or by a saved roster, and collect their bids through a portal that drops the numbers straight into your budget.
No account required
- Subs reach their bid, purchase order, or RFI through a private link. There's no signup wall between them and responding to you.
Insurance and rates captured at the purchase order
- Certificate of insurance and agreed rate are recorded when the PO is issued, so the paperwork exists at the moment it's relevant.
Per-project rates
- A sub can carry multiple named rates, selected per project and per payment, instead of one figure that's wrong on most jobs.
RFIs, submittals, and change orders in one log
- Questions to architects and engineers, submittal review status, and change orders to and from subs all run through the same hub and stay logged against the job.
Lien waivers
- Track waivers alongside the payments they correspond to, rather than as a separate pile you reconcile at closeout.

Works with the rest of the platform
Subcontractors isn't a standalone module — it shares the same job record as everything else in SiteAnchor.
Purchase Orders
Generate purchase orders from the signed estimate, receive against them, and keep stock levels honest without a separate inventory system.
Plans & Markup
Open PDF plans, DXF drawings, and IFC building models in the browser — mark them up, slice through them, and share them with subs without anyone installing software.
Job Costing
See committed versus actual cost on every job while it's running, broken down by cost code and phase, instead of finding out the margin after it closes.
Scheduling
Plan phases on a Gantt with real dependencies, see the critical path, and get told when you've booked the same crew in two places.
For General Contractors
Coordinate subs, schedules, budgets, and clients across every job you have running — without a different app for each one.
For Home Builders
Run long build cycles with draw schedules, selections, and a client portal that keeps buyers informed without keeping you on the phone.
For Remodelers
Manage change-heavy work in occupied homes, with change orders the client actually approves in writing and photos that settle disputes before they start.
Frequently asked questions
Do subcontractors need an account?
- No. Subs reach bids, purchase orders, RFIs, and change orders through a private link with no signup, which is the single biggest reason sub-facing tools go unused.
Can I collect certificates of insurance?
- Yes — insurance and the agreed rate are captured at the point the purchase order is issued.
Can I invite a whole trade at once?
- Yes. Subs can be invited by trade or by a saved custom roster rather than one at a time.
How do I track subcontractor insurance?
- Certificate of insurance is captured against the subcontractor at the point the purchase order is issued, which is the moment it's actually relevant — rather than as a folder someone is supposed to keep current.
Can I compare subcontractor bids?
- Yes. Bids submitted through the sub portal come back into the job budget, so you're comparing numbers in the budget they'll be measured against rather than in an email thread.
Does it handle lien waivers?
- Yes. Waivers are tracked alongside the payments they correspond to, rather than as a separate pile reconciled at closeout.
Can subcontractors submit progress claims?
- Yes. A subcontractor purchase order can follow a draw schedule, with the sub sending and receiving progress claims through the collaborator portal — still with no account to create.
