## The business

Addition+ operates across multiple sectors, supporting a wide range of clients and contractor needs. With varying compliance demands and increasing complexity in the off-payroll landscape, they needed an umbrella partner they could trust to operate ethically, efficiently and to the highest standard.

By partnering with Giant, Addition+ gained that confidence by working with a provider that not only understood the regulatory environment but also delivered with speed, integrity and a human touch.

## The challenge

Working across multiple industries meant that Addition+ was handling a diverse contractor base with different needs, expectations and compliance risks. The team required a partner that could manage these complexities while offering consistency, especially in the face of evolving IR35 legislation and heightened regulatory scrutiny.

In short, they needed a provider who could handle the parts they couldn’t, with the right people, processes and professionalism to match.

## The solution

Giant became Addition+’s go-to umbrella partner, providing fully compliant support to contractors while reducing internal workload for the agency. The partnership was built on trust, shared values and a strong commitment to ethical operations.

Key aspects of the solution included:

**Speed and reliability****  
**Contractors were onboarded quickly, with clear communication and dependable payment processes that ensured minimal disruption and maximum satisfaction.

**Compliance assurance****  
**Giant’s consistent focus on operating at the highest level of compliance gave Addition+ peace of mind across all sectors, no matter the complexity of the assignment.

**Professional support and people-first approach****  
**With a responsive and knowledgeable team, Giant became an extension of Addition+’s operations, delivering service with professionalism and care.

**Knowledge-sharing and training****  
**Giant also supported Addition+ with access to educational seminars and updates on changing regulations, helping them stay informed in a shifting landscape.

- Confidently outsource complex compliance and payroll functions
