A website sold with the software is built to work with it, which is a real advantage. The catch comes if you ever change CRM: the website question comes back with it. See template or bespoke for the honest version of that choice.
Booking valuations from your website
Through Alto's API a website can create an appointment linked to the contact and the property, which is how a valuation booked on your website can land in Alto. Source: Alto's developer documentation, checked 24 September 2026
What we do with Alto
We build the website to take your listings from Alto, keep its own copy so the pages are fast and the feed is used sparingly, and tell you up front if Alto charges for the feed. The valuation journey is designed around how you win instructions, and where Alto lets a website book into the diary, we connect it.
The website stays yours if you ever change CRM: a new feed is connected and everything else carries on. See who owns your website.
