Greenlit locks down your original agreement, then routes every client revision through an interactive delta-pricing workflow — approved, signed and paid before you touch the extra work.
Your clients don't need an account. They review, sign and pay from a private link — no sign-up, no password.

Inside Greenlit · example project
Client requests an extra page → quote $200 → client approves.



Log the contract once: budget, deadline and every scope item the client signed off on.
Each change request becomes a side-by-side cost and timeline delta — nothing is ambiguous.
Clients e-sign the addendum and authorize payment before the extra work starts.
