Signature Acceptance

Q: "Do customers need a Cinderblock account to sign an estimate?"

"No. Customers receive a link by email and can review and sign the estimate directly in their browser without creating an account or downloading anything."

Q: "Can I see when a customer viewed and signed my estimate?"

"Yes. Cinderblock shows you when the estimate was opened and when it was signed, so you always know where each estimate stands without having to ask."

Q: "What happens after a customer signs?"

"You get a notification right away. The signed estimate is saved on the job and is ready to convert to an invoice whenever you're ready to bill. The signature is stored as part of the permanent job record."

Get written approval on estimates without the back-and-forth. Customers sign from any device and jobs move forward.

Automated follow-ups keep estimates from going cold

Set up automatic reminder emails so estimates get attention without manual chasing. The sequence stops as soon as the customer signs or declines, so you’re never following up with someone who’s already responded.

A signed estimate is the starting record for every job

Once signed, the estimate is stored on the job and can be converted to an invoice in one click. The customer’s signature is the written authorization that anchors everything that follows.

We get approvals the same day we send estimates now.

Instead of chasing signatures all week, customers sign from their phone and we’re confirmed before we’ve even left the office.
