The client contract, the statement of work and an assignment letter carry that burden. Together they should show the vendor delivering a defined service, supervising and directing its own staff, and naming the vendor-side manager the specialist reports to, with the clinics receiving a product rather than an extra pair of hands.
Three documents, one consistent story
Assemble them as a set and read them against each other before filing. The contract should describe the engagement as implementation and support of the vendor's platform, with deliverables, milestones and acceptance criteria, and should be silent on any right of the clinics to reassign vendor personnel to other duties. The statement of work should break the deliverable into tasks that plainly require knowledge of the vendor's system.
The assignment letter, issued by the Minden Hills employer, should confirm that Ingrid remains its employee on its payroll, name her supervisor within the company, set the duration, and describe the reporting rhythm. Add the corporate documents establishing the qualifying relationship between the Minden Hills company and its American subsidiary, together with payroll evidence of her one continuous qualifying year abroad within the preceding three years. Where an earlier draft of the contract described hourly billing for personnel, replace it and keep the record of why.
