What's missing_
The feature Lovable does not have
Lovable can build a calculator and the screens to manage its rates. The difference is that ConvertSite already provides a dedicated builder for the pricing interaction.
Change a minimum charge, add a condition or adjust an option directly in the builder. With Lovable, manage those changes through prompts, code or the admin screens your app includes.
Both can produce the customer's quote. Choose the way of managing it that fits your business.
What a customer actually experiences
A visitor completes your pricing calculator, sees their quote on screen, then immediately receives a branded PDF proposal in their inbox: itemised, on-brand, and ready to share with their team. No manual follow-up. No "we'll send a quote within 24 hours." The sale moves faster because the buyer has everything they need the moment they finish the tool.
