What does subcontractor management include?
For a general contractor, subcontractor management is the repeatable process of selecting a trade partner, checking the documents required for the job, agreeing on scope and price, coordinating access and sequence, reviewing completed work, and recording payment. A useful system connects those steps to each project. A contact list by itself cannot show whether a change was approved or whether the current insurance document is on file.
1. Qualify the sub for this scope
Write down the trade, location, proposed start window, and any license, insurance, or project-specific requirements before you request bids. Compare bidders against the same written scope. A lower quote can reflect excluded work, a different material allowance, or a schedule that does not fit the job; resolve those differences before selection.
For California work, use the Contractors State License Board license lookup to check status and classification. Licensing and workers' compensation rules vary by state and scope. Confirm coverage requirements with your contract and insurance adviser, obtain the relevant certificate or endorsement, and verify questions with the issuing insurer or broker. A saved certificate is a record of what was provided; it is not a guarantee that a policy remains in force.
Ask for recent work on a similar scope and call references with specific questions about schedule, change requests, rework, and communication. Keep the answers tied to the bid decision instead of turning one reference into an unsupported rating.
2. Onboard once, then check again for each job
Use a standard packet with the signed subcontract or purchase order, scope and exclusions, price and payment terms, schedule assumptions, site contacts, required license and insurance records, and a tax form when needed. The IRS explains Form W-9 as the request for a taxpayer identification number and certification; ask your accountant how it applies to your payments and reporting. Restrict access to tax and insurance records to the people who need them.
Set a document owner and a review date. Before a new job or a long gap in work, recheck items that may have changed: license status, coverage dates, contact details, and agreed terms. A reminder can prompt a human review; it should not be treated as proof that every document is valid.
3. Connect scope, changes, and schedule
Give each assignment a written scope with included work, exclusions, materials, price basis, milestones, and an approval contact. A purchase order can make the approved amount and revision history easier to find, but the governing subcontract and local law determine the actual obligations. When the field condition changes, record the requested change, price and time impact, and approval before relying on a new amount. Keep the original and revised scope together.
On the schedule, record the predecessor that makes the sub's work possible: permit, inspection, material delivery, access, or another trade's completion. Confirm the near-term start window directly with the sub and note the response. If a predecessor slips, identify affected trades and update the owner-facing plan; a calendar entry alone does not tell them why the date changed.
4. Review work and pay from the same record
For each payment request, compare the billed milestone or quantity with the approved scope, accepted changes, and field evidence. Record who checked the work, what was disputed, and when payment was released under the contract. A predictable process helps both sides understand the amount due; no generic three-day or seven-day promise fits every contract.
Lien releases need particular care. California's CSLB forms and guidance distinguish conditional and unconditional releases for progress and final payments. A conditional release is tied to actual payment. Do not ask a claimant to sign an unconditional release as proof of money they have not received. Paying one party does not automatically establish that every sub or supplier has been paid. Have local counsel review your form and sequence.
5. Test the software with one real job
Bring a redacted subcontract, an expiring document, a scope change, and a disputed payment request to a vendor demo. Ask the vendor to show, in the plan being quoted:
- Where the approved subcontract, license, and insurance records live; who can view or change them; and how the system shows a missing or expired item.
- How a purchase order and change are approved, versioned, and exported.
- How a schedule delay reaches the affected trade and how the revised date is recorded.
- How a sub submits a payment request, how a GC compares it with approved scope, and what an owner or accountant can audit later.
- What the system does when a document expires: notification, warning, hold, or another action. Ask for a live demonstration rather than assuming a hard block.
Opsite's published pricing lists Purchase Orders on Starter at $349/month. It lists Sub Portal, Compliance Hub, and Lino on Professional at $649/month, with further automation on Enterprise. The feature descriptions describe those tools, but a description does not verify every alert, permission, or payment rule for your account. Request a demonstration of your workflow and confirm current plan terms before buying.
If you are comparing platforms, use the contractor software scorecard to record whether each vendor actually completes this test. Or request a contractor workflow fit review with one redacted example job.
This is general operational information for contractors. Contract, licensing, insurance, tax, payment, and lien requirements depend on the jurisdiction and job; consult the appropriate licensed professional.
