Agency teams rarely call it scope creep. A client asks for one more version, channel or deadline change, and the work starts before anyone makes the commercial decision. I built MarginRail to create that pause: compare the request with the agreed scope, see the boundary evidence and estimated value, then choose to charge, trade, defer or deliberately absorb it. It is selective, not surveillance—MarginRail only checks the request a team submits, and does not continuously read Slack, Teams or mailboxes. The product is live at £99/month or £990/year after a 14-day trial, with unlimited teammates. I’d value blunt feedback from agency owners, operations and client-services leads: where does this decision currently happen in your workflow, and what would make the evidence useful enough to act on?
