MarginRail
ACTIVECatch unpriced client work before your agency says yes
Launched July 21, 2026
About MarginRail
MarginRail provides a commercial checkpoint for agencies, letting teams paste the agreed scope and capture client requests via Slack, private links or email. It flags likely out‑of‑scope work, estimates potential value, and presents options to charge, trade, defer or absorb before saying “yes”. Approved changes generate client‑ready approval links and enter an invoicing queue with CSV export. Unlimited teammates are supported with flat‑rate pricing and no per‑seat fees.
