A main contractor carries a compliance risk a single building company never does: you're accountable for the companies and people you don't directly employ, across projects running at once. A subcontractor whose insurance lapsed, a worker without the right ticket, a RAMS nobody reviewed — any of these is your exposure. This guide is about software that gives you oversight of the whole supply chain, not just document production. It sits under the best construction compliance software guide.
What should main contractor compliance software manage?
Everything from the company at the top of the chain down to the individual on site: subcontractor onboarding and prequalification, verified company records and insurances, the competence of every worker put on your projects, RAMS and construction phase plans, site controls, expiry oversight, and a single view across all live projects. The list is longer than a builder's because the job is oversight, not just your own paperwork.
Contractor onboarding
Invite subcontractors, collect their company profile, documents and insurances, and get them approved before they reach site.
contractor onboarding →Prequalification
Check each subcontractor meets your standards up front — accreditations, insurances, policies and capability — so only qualified firms are engaged.
contractor prequalification →Worker competence
See that the people each subcontractor puts on your site actually hold the cards, tickets and training the work requires.
worker compliance →RAMS & CPPs
Receive and review subcontractor RAMS against good practice, and hold the construction phase plan they sit under.
RAMS management →Site controls
Site inductions, sign-in and site rules, so you know who is on each site, inducted and briefed.
site inductions →Expiry oversight
Every subcontractor insurance, accreditation and worker ticket tracked with alerts, so a lapse is flagged rather than discovered on site.
certificate and expiry tracking →Multi-project visibility
One view of compliance across every live project — which contractors and workers are compliant, and where the gaps are.
compliance across multiple sites →Audit evidence
A defensible record across the supply chain — who was approved, on what basis, and what was in place when — producible on demand.

Contractor onboarding and prequalification
Oversight starts before anyone reaches site. The flow is: invite the subcontractor, they build a company profile and upload documents and insurances, you prequalify them against your standards, approve them, and allocate them to a project. Doing this in software rather than by email means the documents are verified and dated, the approval is recorded, and nobody starts work on the strength of a promise. See contractor onboarding and contractor prequalification.
Worker competence and training
Approving a subcontractor company isn't enough — you need confidence that the specific people they put on your site hold the cards, tickets and training the work requires. This is where a portable worker passport and a training matrix matter most: competence follows the worker across employers and projects, and you can see it at the point they arrive, backed by worker compliance records.
RAMS, CPPs and site documentation
Across a supply chain you don't just write your own RAMS — you receive and review your subcontractors', and hold them under the project's construction phase plan. Keeping RAMS management and the construction phase plan in the same system means the project-level plan references the task-level RAMS that actually apply, per project.
Compliance across multiple construction projects
The defining main-contractor need is seeing it all at once. Rather than a folder per project and a memory of what's outstanding where, you want one view across every live project showing which contractors and workers are compliant and where the gaps are. That's the same portfolio capability set out in compliance across multiple sites, applied to construction projects.
Contractor document and insurance expiry tracking
A subcontractor compliant on Monday can be non-compliant on Friday when an insurance renews late or a ticket lapses. The platform tracks every document's expiry across the chain and alerts you before it lapses — see certificate and expiry tracking — so you chase a renewal instead of finding an out-of-date contractor already working.
Creating a digital construction supply chain
Put together, this is a connected chain rather than a pile of PDFs. Each level feeds the one above, and compliance is visible end to end:
This is why winning the main contractor matters for the whole chain: when the organisation at the top runs compliance on one platform, its subcontractors are drawn onto it too, keeping their own documents and evidence in the same place.
Main contractor software vs separate systems
The alternative is a CRM plus a RAMS app plus a training spreadsheet plus a contractor portal plus a document store — several logins and data that doesn't join up, so the portal doesn't know a worker's ticket lapsed and the RAMS review isn't tied to the project. One connected platform keeps company, project, subcontractor, worker, document and RAMS joined, which is both cheaper and far stronger when you need to prove supply-chain compliance on demand.
Why use Complys for main contractor compliance?
Because it does the whole oversight job in one place — onboarding, prequalification, worker competence, RAMS, site controls, expiry alerts and multi-project visibility — at a price that doesn't require an enterprise budget.
