For manufacturers and machine shops
Documented customer approvals, before production begins
OrderApproval gives you a clear, verifiable record of customer sign-off on every order and engineering file. Send drawings and CAD models for review, and receive a signed decision — timestamped and audit-ready.
$5 per user / month after trial. No credit card required.
How it works
Three steps to a signed approval
Create the order
Add order details and attach STEP files, PDF drawings, and photos. Everything lives in one place.
Send for approval
Your customer gets a secure link — no account needed. A one-time email code verifies it's really them.
Get a signed decision
They review the 3D model and drawings in the browser, then approve with a typed signature — or request changes with notes.
Features
Built for how manufacturing approvals work
3D CAD viewer in the browser
Customers rotate, pan, and zoom your parts without installing anything. PDFs and images render inline too.
Verified approvals
Email one-time codes confirm the right person is signing. Every decision records name, time, IP, and device.
Complete audit trail
Sent, opened, viewed, approved — every event is timestamped. Export-ready evidence when disputes come up.
Revision control
Changes requested? Cut a new revision. Old links are invalidated automatically so nobody approves stale files.
No customer accounts required
Approvers open a secure link and verify their email — no software to install and no account to create. Less overhead for your customer, faster sign-off for you.
Controlled forwarding
Your contact can bring a colleague into the review when sign-off requires another stakeholder. Every added recipient is tracked and logged.
Nervous about sharing your designs? So are we.
Your engineering files never become public links. They live in your organization's private workspace — encrypted in transit and at rest, shown only to recipients who verify their identity. Your own activity log shows who opened each file, and our team never browses your documents.

TLS in transit and AES-256 encryption at rest.
