- The CONTORA Revolution
FREE IR35 Software for BUSINESS
Retain your key contingent work-force 'outside' of IR35
The CONTORA platform allows you to transition your off-payroll suppliers to an outcome-based framework thus remaining ‘outside’ of IR35.
If your existing contractors are walking away rather than moving to Fixed Term Contracts (FTC) or umbrella companies, then CONTORA is your solution.
Don't let your projects fail because your current processes don't accommodate outcome-based delivery by contractors.
CONTORA has been developed to help all parties in the resource supply chain. It is a delivery model that ensures full compliance of 'outside' IR35 engagements.
- Statements of work
- Work sign-off
- Invoice approvals
- Evidenced ways of working
Compliant
CONTORA helps define and document your ways of working and your suppliers’ ways of working, to support correct status determinations for off-payroll engagements.
Control
The entire off-payroll way of working can be fully managed within CONTORA.
Convenient
You can confidently issue your suppliers with a Status Determination Statement, based on the documented ways of working of your complete resource supply chain.
Mitigate Risk
The whole contractor/client relationship is manged through CONTORA via Statements of Work. All milestones, deliverables and payments are managed through this portal. Everything is fully transparent, recorded and evidenced.
Guidance
CONTORA can help you re-align your off-payroll ways of working in a compliant and fully managed way.
EFFICIENT
CONTORA will contain a pool of IR35 compliant contractors to which you can advertise your Statement of Work. It will reduce your need for using third parties to find the best contractors. It will reduce the amount of paperwork you need to do. It will save you time. It will save you money.
Contora makes your contracts and statements of work visible, interactive and collaborative, rather than paper-based, inert and difficult to manage.

FAQ about Contora
- How much does CONTORA cost?
- How much does it cost for me to use CONTORA to source IR35 Compliant Contractors?
This service is free of charge. You can upload your Statement of Work for contractors to find and they will apply to you.
- What if I already have a list of Contractors I like to use?
No problem. Just tell your Contractor about CONTORA (it is totally free for them to register), upload your Statement of Work and you can both use CONTORA to manage your project in an IR35 compliant way with a complete 360-degree view. Even the drafting of documents can be done within the system so changes can be tracked.
- I have previously been told that our way of working is not IR35 compliant.
If you have previously done an assessment, it may have been bias depending upon how that assessment was done – CONTORA is fully independent for a totally non-bias point of view. There is no charge for you to complete the questionnaire and get a real sense check on what you have previously been told. CONTORA will offer guidance as to how to become compliant.
