In short_
Squarespace is a strong choice for a business website: explain your services, publish your work and sell products. It also has forms with conditional follow-up questions, plus tools for proposals, estimates and invoices.
ConvertSite is a better fit when the visitor needs a price calculated from their answers. Turn measurements, location, options and minimum charges into a quote they can see while they are still on the page.
If you need a portfolio, blog or conventional online store, Squarespace may be all you need. If quoting each enquiry by hand is slowing you down, use ConvertSite for that workflow. You can embed it in your Squarespace site instead of rebuilding the whole website.
In short_
Outgrow is a content marketing platform built for lead generation campaigns: quizzes, assessments, ROI calculators that attract and capture contacts.
ConvertSite is built for businesses that need to qualify buyers, show real-time pricing, and close sales without a sales call.
If you sell something with variable pricing or complex configuration, ConvertSite is purpose-built for that. If you're running content campaigns and need branded quiz funnels at scale, Outgrow has the depth.
The real purpose_
What each tool is actually built for
Squarespace is built around your website and your business content.
ConvertSite is built around the customer's price question.
Ask for the details that affect the job, then calculate the result using your own formulas and conditions. A cleaning business can price by area, frequency and extras. An installer can account for options, travel and a minimum charge.
The result can live on a standalone page or inside the website you already have.

What's missing_
The feature Squarespace does not have
The missing step is a price the visitor can work out for themselves.
Squarespace can collect the details and help you prepare a proposal or estimate. Its product variants can also have different prices. Those are useful features, but they do not document a calculator that combines the customer's measurements, location and choices into your service quote.
With ConvertSite, the customer supplies the inputs and your rules calculate the result. The Documents add-on can turn those answers into a branded PDF proposal. You can keep your Squarespace website and add this workflow where customers need it.
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.

How the customer gets their price
With Squarespace...
With ConvertSite...
A visitor enters the area, chooses the service and selects the extras. Your formulas calculate their estimate on the same page. Someone booking a small apartment and someone booking a large house see different numbers because the inputs are different.
You decide what happens next: collect the enquiry, take a payment or guide them to a booking.
