No — keep it. Those tools are good at the roster: who is available, who is booked, who checked in. What they do not do is handle the client side of your business: the request, the estimate, the approval, the project manager, the billing. That is the layer we build. When an estimate is approved, the system produces a staffing brief — the shifts, roles, headcount, venue, and notes as a PDF and a CSV — that your recruiter imports into the roster tool or keys in once, and hours come back the same way for reconciliation. We do not integrate with the roster tool's API, by design: that keeps you free to change tools, and keeps your build to eight weeks. If you are running the roster in a spreadsheet today, that works too — the platform becomes the system of record and the sheet retires when you are ready.
