  • Assign from the calendar or dispatch board
  • Skill and compliance matching
  • Subcontractors accept or decline via portal
  • Push notification and email alerts for new assignments
  • Track subcontractor time on site
  • Same reporting as employed workers

Frequently asked questions

Do subcontractors need to pay for access?
No. Subcontractor portal access is free. They log in with their own credentials to see jobs, submit invoices and upload documents. There's no per-subcontractor charge.
How does CIS verification work?
You enter the subcontractor's UTR and HMRC details. Gaffer checks their CIS status and applies the correct deduction rate (0%, 20% or 30%) to all invoices. Monthly returns are generated automatically.
Can I block a subcontractor from jobs if their insurance expires?
Yes. You set mandatory compliance requirements per job type. If a subcontractor's insurance, qualification or certification expires, they're blocked from being assigned to new jobs until it's renewed.
Can subcontractors see my other subcontractors or internal data?
No. Each subcontractor only sees their own jobs, invoices and documents. They have zero visibility into your other subcontractors, employees or financial data.
Does this replace my accounting software for subcontractor payments?
No — Gaffer handles the workflow (submit, approve, CIS deductions) and then exports to your accounting software (Xero, QuickBooks, Sage) for payment. It's the front-end process, not the bank transfer.
How many subcontractors can I manage?
Unlimited. There's no cap on the number of subcontractors you can add, regardless of your plan.
