Frequently asked questions
- Can a customer sign an estimate from their phone?
- Yes. You send a secure link by email and the customer opens it on any phone, tablet, or computer — no app to install and no account to create. They review the estimate, sign with a finger or typed name, and you both get the completed PDF.
- How do change orders work?
- Save your change-order form as a reusable template, fill in the scope and cost, and send it for signature before the extra work starts. Each signed change order keeps a timestamped record, which helps avoid disputes about what was approved and when.
- Can I collect a signature in person on site?
- Yes. Open the document on your own device, hand it to the customer to sign, and finish on the spot. The signing session still records the date, time, and device so the record is complete.
- Are signed estimates and contracts legally valid?
- Electronic signatures are generally enforceable under the ESIGN Act and UETA for the kinds of agreements contractors use every day. This is general information, not legal advice — confirm the requirements for your trade and state.
- Can I reuse the same forms for every job?
- Yes. Templates let you save your standard estimate, contract, work order, and change order once, then send them for a new job in a couple of minutes instead of rebuilding them each time.
- What does it cost?
- Pricing is a flat monthly fee by plan, not a charge per document or per envelope, so a busy month costs the same as a slow one. You can start on the free plan and upgrade when you need templates or more team members.
