Use case

Sign a vendor quote online — approve it from the truck.

You're a sole proprietor, you're on the move, and a vendor just sent over a quote you want to lock in. Tap to approve it on your phone — and walk away with a clear record of exactly what was agreed and when.

"Approved" over text isn't a record. It's a guess.

When you run a one-person operation, decisions happen between jobs — in the truck, on a site, in a parking lot between appointments. A supplier sends a quote, you want to say yes, and the work needs to start. So you fire back "looks good, go ahead" in a text and move on.

Then the invoice arrives and it's higher than you remember. Or the scope "always included" an add-on you never saw. Now you're scrolling through messages trying to reconstruct what you actually agreed to, and a verbal "go ahead" turns out to be worth exactly nothing when the numbers are in dispute.

You don't need a contracts department. You just need the version you said yes to, signed and dated, so there's nothing to argue about later.

How sign.pink solves it

Approve with a tap, anywhere

Review the line items and sign the quote from your phone on the job — no laptop, no printer, no waiting until you're back at a desk.

Locks in the exact version

The signed PDF captures the precise scope, price, and date you approved — not a fuzzy 'go ahead' from a text thread.

A clear record of when

Every signature is time-stamped, so it's obvious exactly when you approved the quote and on what terms.

Affordable for one person

$3/month, unlimited, no per-seat fee. Approving an estimate shouldn't cost more than the coffee you bought on the drive over.

Approve a quote in three steps

  • Open the quote link the vendor sent — or upload the estimate yourself to send for sign-off.
  • Review the line items, scope, and total, then tap the signature field and approve.
  • Everyone gets the finished, time-stamped PDF — the exact version that was agreed, with a tamper-evident audit trail attached.

Is a signed quote enforceable? Yes. An electronically approved quote or work authorization is binding under ESIGN and UETA in all 50 states, and the tamper-evident audit trail records exactly what scope and price you signed off on. See why e-signatures are legally binding for the details.

Vendor quote approval — FAQ

Yes. When you sign a quote, estimate, or work authorization electronically, that approval is binding under the U.S. ESIGN Act and UETA and enforceable in all 50 states. sign.pink records a tamper-evident audit trail, so there's a clear record of exactly what scope and price were approved, and when.

Say yes once, on the record, and get the job moving.
