Sub-Contractor Management: Paying and Tracking External Engineers

Onboard, dispatch, track and pay sub-contractors without losing margin, compliance or control over the customer experience.

8 min read

Sub-contractors let you scale capacity without the fixed cost of employees. They also lose you margin, customer trust and compliance if you don't track them properly.

Onboarding sub-contractors

  • Public liability insurance — copy on file, expiry tracked
  • Trade qualifications (Gas Safe, NICEIC, etc.) — verified
  • UTR for CIS deductions if construction
  • Signed sub-contractor agreement — pricing, response times, brand standards

Dispatching

Sub-contractors get the same mobile app as employees. Same job notes, same photo evidence, same customer comms. The customer can't tell the difference.

Paying

  • Auto-calculate sub-contractor payout per job (% or fixed)
  • Weekly self-billing invoice generated and emailed
  • CIS deductions applied where required
  • One-click bulk payment via BACS

Margin protection

Tag every job with the sub-contractor cost so you see true margin per channel and per job type. Some channels only work in-house.
