The contractor portal is the heart of the eFile system. This is where the client and contract information, deliverables and documents are set up and made available to a client and/or HMRC in a secure environment.
Here the contract can be set up to be inside or outside IR35. Outside, allows you to structure the contract by individual deliverables and manage the change lifecycle of the deliverables and assign substitutions if necessary.
The portal also allows the contractor to store all historical contracts and documentation in a secure way in the event that are needed in the future.
The portal is the place where you setup the Client and HMRC portals to add new features to your eFile service.
