CollabBrief keeps every sponsorship term, deadline, invoice and renewal in one place, then shows you the delivered work nobody invoiced and the usage windows that quietly expired. A signed deal stops disappearing between your inbox, calendar, brand contact, and accountant.
Forward a brief to a private inbox and it becomes an editable deal draft. Check a new sponsorship against the category exclusivity, territories, usage windows and publication dates you already agreed. Invoice once, then let the follow-up ladder chase the payment.
Every new workspace starts on a 14-day Pro trial with no card, and falls back to a permanent Free plan.
