Case study
The solution we deliver in the Pharmaceutical field is unique, rendering standard off-the-shelf technologies insufficient to meet their distinct operational requirements. Giant demonstrated a deep understanding of both our needs and those of our client, working closely with us to co-create a bespoke offering tailored to these specific demands. From initial design through to implementation, the project was successfully delivered within four months, with no disruption to client services. This outcome was only achievable through the strength of our collaboration and shared commitment to excellence.

Case study
Giant's professionalism and proactive support have made them an invaluable partner. They were able to quickly set up the solution for us and have been a dream to work with since. The secure online timesheet system is a game-changer for us, providing a reliable way to manage timesheets and approvals coupled with all our workers being payrolled accurately on a weekly basis.

How it works
From conversation to running, typically within weeks
1
Discovery call and workforce audit
We get under the bonnet of your current setup — worker types, engagement structures, which agencies supply which roles, and where compliance stands today.
2
Platform configuration
Our proprietary platform is set up around your structure. Agencies, workers, managers and approval chains are all configured before anyone goes live.
3
Contractors go live
Screening runs, onboarding flows, timesheets come in, payroll processes, one invoice goes out — the same process for every worker.
4
Ongoing management and reporting
Real-time headcount, spend and compliance status. Your dedicated team provides reviews as standard, with daily contact where it's needed.
What's included
Everything from first check to final payment
The service covers the full contractor lifecycle. Each component runs through Giant's proprietary platform and one set of processes, applying the same standard to every worker, regardless of which agency placed them.
Background screening
Right-to-work, ID, CV verification, criminal record and reference checks. Available globally with country-specific compliance built in. A workforce audit is the natural first step where there are gaps.
Contractor onboarding
Document collection, IR35 status, engagement type, and platform access, handled to a consistent standard across every worker in your population.
UK and global payroll
UK payroll across umbrella, limited company, CIS and PEO models. Global payroll, employer of record and agent of record for international contractor populations.
Timesheet management
Time capture, approvals, and pay-and-bill, built into the same proprietary platform your contractors and managers already use.
Reporting and visibility
Real-time headcount, spend, and compliance status across your full contractor population, in one view, regardless of how many agencies are involved. Structured reviews come as standard.
One named team. Not a helpdesk ticket.
Your dedicated account management team stays close throughout, so you always have a named point of contact.
Who it's for
Two situations. The same underlying problem.
Recruitment agencies
Deliver more than placements
Clients want one system, one invoice, and every contractor properly checked. We make that possible without you building an operations team.
Moving into new markets? We handle the local payroll and compliance, so expansion doesn't stall on back-office complexity.
Workforce management under your own brand. The platform runs under your name. Giant runs the delivery.
Paying contractors before clients pay you? Our funding solutions bridge the gap, so cash flow stops limiting how many contracts you take on.
End-hirer organisations
Get visibility and control
Separate invoices, separate formats, no clean view of what your contractor population actually costs. We consolidate it into one.
Compliance is inconsistent across your supply chain. Our neutral managed service applies the same standard to every worker, whoever placed them.
Growing internationally? Our global payroll covers markets your current setup can't reach, including employer of record arrangements.
Told your population is too small? It probably isn't too small for us. Bring us the details and we'll tell you honestly.
FAQ
Got questions? We have answers.
What does Giant actually manage?
Giant manages the full operational lifecycle of your contractor workforce — from pre-placement screening through to offboarding. That covers right-to-work checks, onboarding, IR35 status, timesheet collection, payroll processing, and final exit administration. Everything that happens after a contractor is placed, handled through one proprietary platform and one set of processes.
Do you work alongside our existing agencies?
Yes. Giant operates as a neutral vendor managed service, sitting behind your supply chain so your agencies keep placing and maintain their client relationships. We handle the operational layer underneath. PageGroup, Morgan McKinley and Cielo all use Giant's platform while continuing to run their own client-facing services.
What engagement types do you support?
We support umbrella, limited company, CIS and PEO models for UK contractors, and employer of record and agent of record arrangements for international populations.
Can you handle contractors placed across multiple agencies?
Yes — that's precisely the problem we're built to solve. Giant applies the same onboarding, compliance and payroll process to every contractor regardless of which agency placed them, and consolidates everything into one invoice and one reporting view.
How quickly can you go live?
From initial discovery call to contractors going live is typically a matter of weeks. Pearson Education had 2,500 workers on payroll by week three. The exact timeline depends on the size and complexity of your contractor population and the number of suppliers involved.
Do you cover international contractor populations?
Yes. We provide global payroll and employer of record services for organisations with contractors in international markets. Imperial Brands went live across the Netherlands, Poland, Spain and the UK simultaneously.
Is there a minimum contractor population size?
No fixed minimum. Larger providers may have quoted a minimum that ruled you out. In most cases your population isn't too small for us — bring us the details and we'll tell you honestly.
We're an agency — can Giant run our back office under our brand?
Yes. The platform can be white-labelled so your clients see your service. Giant runs the infrastructure underneath — UK and global payroll, background screening, timesheet management, and consolidated invoicing.
Let's talk
Most conversations start with a specific problem.
A compliance gap, a client asking for more, contractors spread across agencies with no single view. Whatever the situation, we'll tell you honestly whether we can help.
