How does GPTForm calculate prices accurately without hallucinating?
GPTForm separates natural language conversation from numerical pricing. The AI gathers the project parameters, which are evaluated by a deterministic formula calculator engine according to your exact pricebook formulas.
Can I create complex calculators with conditional rules?
Yes. You can configure formulas with conditional branches, square-foot multipliers, minimum base charges, volume discounts, and variable labor rates matching Jotform and Elementor calculator standards.
Do customers need to download an app to sign the quote?
No. E-signatures work smoothly directly in the web browser on desktop, tablet, and mobile. Customers sign with their finger or mouse and receive a signed PDF confirmation immediately.
Can the quote turn into a booked job and invoice automatically?
Yes. Upon client acceptance, the quote converts into an active job, syncs to your calendar, generates an invoice, and prompts for deposit payment in one seamless sequence.
