Every subcontractor relationship carries a compliance obligation, and the one you forget about is the one that turns up in an insurance claim.
TL;DR Nobody works until the document pack is complete. Track every expiry date with automatic reminders at 60, 30 and 7 days. Pay fast and consistently. Score performance on data you already collect.
The document pack
Define it once and never accept a partial set.
Typically required
- Tax documentation appropriate to your jurisdiction. In the US this means a W-9 for a US-based contractor.
- Public liability insurance certificate, with the expiry date.
- Employer’s liability, if they have their own staff.
- Professional indemnity, where the work warrants it.
- Trade licences and certifications, with expiry dates.
- Vehicle insurance covering business use.
- Signed subcontractor agreement.
- Bank details for payment, verified.
- Health and safety documentation, where required.
Requirements vary by jurisdiction and by trade. Confirm your list with an accountant and an insurance broker rather than copying a generic one, and revisit it annually.
No documents, no work
This is the rule and it has to be absolute.
How it fails in practice: a job comes in, a subcontractor is available, the paperwork “will follow”, and it never does. Then something goes wrong.
Automate the gate
- Subcontractor added to the system, marked “pending”.
- Automatic email with the document checklist and upload links.
- Reminders at 3, 7 and 14 days.
- Each document reviewed and approved individually.
- Status only flips to “active” when all are approved.
- Dispatch cannot assign a pending subcontractor. Enforced by the system, not by memory.
The system enforcement is the important part. A policy that relies on somebody remembering during a busy week is not a control.
Insurance expiry tracking
The highest-risk item and the easiest to automate.
On approval, record the expiry date as a structured date field.
Then automate
| Days before expiry | Action |
|---|---|
| 60 | Reminder to the subcontractor |
| 30 | Second reminder, copy internal |
| 7 | Escalation, internal alert |
| 0 | Status flips to inactive automatically |
The automatic status change at expiry is essential. Without it, reminders get ignored and expired cover is discovered after the incident.
Working with an uninsured subcontractor can invalidate your own cover. This is not administrative tidiness, it is the risk that ends businesses.
Payout triggers
Fast, consistent payment is your competitive advantage in retaining good subcontractors.
Automate the chain
- Job marked complete by the subcontractor, with photos and signature.
- Internal quality check, if required.
- Payment record generated automatically from the agreed rate.
- Approval, one tap.
- Payment scheduled in the next run.
- Remittance sent automatically.
Set a fixed payment day and hold it. Predictability matters more to subcontractors than speed. The best ones prioritise the people who pay when they said they would.
Self-billing, where permitted, removes the invoice chase entirely. You generate the payment record from the completed job. Check the tax rules that apply before adopting it.
Rates and scope
Document per subcontractor
- Rate structure. Day rate, hourly, per job, percentage.
- What is included. Materials, travel, waste disposal.
- Payment terms.
- Cancellation and standby terms.
- Warranty obligations on their work.
The warranty clause is the one most often missing. If a subcontractor’s work fails in eight months, who returns and who pays? Agree it in writing at onboarding, not at the point of failure.
Performance scorecards
Score on data you already collect. Do not build a survey.
| Metric | Source |
|---|---|
| On-time arrival | Time tracking |
| Job completion rate | Job records |
| Callback rate | Complaints and return visits |
| Photo and record completeness | Job records |
| Customer feedback | Post-job survey |
| Documentation currency | Compliance status |
Review quarterly. Share the scorecard with them, because most performance problems are informational rather than attitudinal.
Act on it
- Top performers get first refusal on work. Say so explicitly, because it drives behaviour.
- Mid performers get the specific feedback.
- Consistent poor performers get one clear conversation, then removal.
Volume of work is your strongest lever. Better than rates, and it costs you nothing.
Classification risk
Worth stating plainly. How you treat a subcontractor affects whether authorities regard them as a contractor or an employee, and the tests vary by jurisdiction and are applied strictly in many places.
Factors commonly considered
- Control over how and when the work is done.
- Whether they can send a substitute.
- Whether they work for others.
- Who provides tools and materials.
- How integrated they are into your business.
Get advice specific to your jurisdiction. Misclassification is expensive and retrospective. This article is not that advice.
Onboarding beyond compliance
The paperwork is the gate. The onboarding is what makes them work well.
- Your standards, in writing. What a completed job looks like.
- Access to your training videos, at least the customer-facing ones.
- Introduction to the systems they will use.
- Named contact for questions.
- A first job with a check-in, not a cold start.
Subcontractors represent you to the customer. The customer does not know or care about the contractual distinction.
Measure it
- Time from first contact to fully approved. Should be days, not weeks.
- Percentage with current documentation. Must be 100.
- Expired documents caught before expiry, versus after.
- Payment on agreed date, percentage.
- Callback rate, subcontracted versus in-house work.
Build the insurance expiry reminders this week. It is a date field and three scheduled messages, and it addresses the single largest uninsured risk most growing service businesses carry.
