Keep Factory Lines Running — Sign Work Orders & Supplier Deals Without the Paper Chase
Eliminate production bottlenecks from paper delays and slow approvals. Complete supplier master agreements, engineering change notices and equipment maintenance sign-offs in minutes on mobile — plus smart AI to catch raw material price traps before you commit.
Sign Right on the Shop Floor or Loading Dock
Send delivery sheets, maintenance releases, and equipment sign-offs straight to your team or vendors via email. Technicians and drivers can open the link on their phone, sign with a finger in 30 seconds, and get back to work — zero app downloads or passwords needed.
Stop Waiting Around for Sign-Offs
Don't let an unapproved engineering change (ECN) or QA report stall a production run. Set up a simple signing order — your quality inspector signs first, the plant manager gets it next, and your supplier gets the final approved copy automatically.
Catch Hidden Price Hikes Before Signing
When a raw material supplier or machine vendor sends over a dense 30-page agreement, upload it to Indigo. In seconds, our AI highlights price escalation triggers, delivery penalty traps, and restrictive warranty limits in plain English so there are no surprises.

Never scramble through dusty file cabinets during an audit again. Every signed document comes with a certified digital completion certificate recording exact UTC timestamps, email verifications, and IP records that satisfy quality auditors and inspectors.
