Define the assignment
The source shop should record the Partner, work scope, requested completion, authorized compensation, vehicle or unit identity, and the files needed to begin. The Partner should acknowledge or decline the exact assignment rather than receive an open-ended account login.
Give the Partner a workday
The Partner needs receiving, VIN or unit verification, photos, scan reports, inspection findings, job status, ETA or delay updates, additional-work proposals, completion, and payment-request tools. It does not need customer invoices, owner expenses, bank accounts, or unrelated work.
Preserve changes and money
Additional work should move through a proposal and owner decision instead of altering the original agreement silently. Partner payments should show authorized, requested, approved, paid, disputed, and outstanding amounts with source history.
