CONTORA is a free platform to help Contractors/PSCs legitimately operate 'outside' of IR35.

No catches, no gimmicks. We’re not an umbrella, an agency, a consultancy or a client.  CONTORA is a toolset, a platform, a framework thats already being adopted by a growing number of clients and consultancies to deliver fully compliant service

What is Contora®?

The CONTORA® framework allows you to manage and grow your PSC or consultancy in an IR35 compliant way. CONTORA® is a brand new, engagement framework for suppliers (contractors and consultants) and engagers (clients) and intermediaries (agencies and consultancies) to provide outcome based services outside of IR35 regulations through easy to manage Statements of Work (SoWs)

How Contora® works

The process is simple. Work your way through the system - as soon as you have completed one step, the next step is unlocked for you.

Before you know it, you will be working in a fully compliant, 'outside' IR35 way

Interactive Statements of Work

To support IR35 compliance it’s important to ensure that the engager and suppliers are on the same page, not just contractually but also in their ways of working.

There is much talk about Statements of Work being used as a means to justify and 'outside' IR35 determination and in some case this is true but for contractors and PSCs a Statement of Work is often focused on project level deliverables over which you have little or not control and we believe its like trying to fit a square peg into a round hole.

With CONTORA we have taken a bottom up approach to the SoW model and focused on what the contractor actually does. As a result, we created Defined Service Engagements (DSE).

A Defined Service Engagement simply documents the 'fee payer and hirer' expectation of the services they want you to deliver over the duration of the engagement and breaks these down in to milestones against which they can measure performance for payment.

Using a Defined Service Engagement allows you to demonstrate:

Better together. Source, engage, deliver.

Already have IR35 insurance or been assessed outside IR35? Here’s why you should still join CONTORA®...

Already IR35 Insured Contora

Insurance and assessments provide you with re-assurance that, contractually, all parties have agreed the content of a status determination. Once the assessment and insurance are in place it could be assumed that there is no more to worry about. This couldn’t be further from the reality. You are at the start of your compliance journey.

After April 2021 HMRC will begin investigating and challenging the IR35 determinations made by medium and large companies, and an area of particular focus will be on actual ways of working and whether or not these are truly aligned with the evidence used to originally create the determination result.

For example, if the determination stipulates substitution is possible and yet there are no clear methods to execute this, then it could be deemed invalid. Likewise, if the determination states that risk will be demonstrated by statements of work, but in reality you continue to be directed or controlled outside of this with no evidence to the contrary, then HMRC may deem this as invalid.

CONTORA® provides all parties with a single, immutable audit trail of contractual deliverables and ways of working to support IR35 compliance throughout the contract lifecycle.

Better together. Source, engage, deliver.

Remaining 'outside' IR35 requires action by you...

Change doesn't happen over night but to remain operating 'outside' of IR35 you need to act now...

If you’re not already adjusting the way you approach your off-payroll engagements then its likely  that you will end up being placed ‘inside’ IR35 by your clients.

Much focus has been placed on the contractual key tests (Mutuality of Obligation, Substitution, Control)  but there is another key factor that clients are considering when completing their status determination statements; most contractors are not properly set up to operate as a bone fide business that can create and deliver outcome based services.

Just running a limited company and engaging an accountant does not automatically entitle you to an outside IR35 status determination if you are still providing CV’s and signing contracts that have no clear deliverables and are not aligned with your actual ways of working.

CONTORA helps you make some very simple changes  that enable you start demonstrating your true potential.

Is CONTORA® just an umbrella company in disguise?

CONTORA® is an independent framework that can be used by any organisation wishing to retain their off-payroll services ‘outside’ of IR35 through their existing limited company. It is NOT an agency or umbrella company. You are in complete control.

CONTORA® manages contracts, statements of work and deliverables more efficiently;  It helps organisations transition your ways of working toward a delivery/outcome based model whilst improving augmentation efficiency and reducing costs.

CONTORA® can be used by clients, agencies, consultancies and independent contractors involved in off-payroll engagements, to engage suppliers ‘outside’  IR35 compliance and provide full transparency of product deliverables.

As a contractor, CONTORA® is free to use can help you grow your business and engage multiple clients, further proving your status as a bone-fide business.
