The pagebuilder within BigCommerce is not sufficient, not even close. If you want something else, you have to pay almost double the monthly cost. After that i tried the headless version, only to find out that de support really do not seem to know that headless is an option. Then the next problem came along, the tracking of data needed to make the (growth in) conversions. But no, this is another thing that BC does not care about, as long as you pay. Again, support knew nothing, documentation was a joke... But i also could not change the language settings to the native language i had to use, so the website would not look professional at all. So, even without putting my website online, and it has only been a couple months, they refuse any form of refund. SO PLEASE, do yourself a favor, and look elsewhere. Especially when you are a small or starting webshop and DEFINITELY when you do not want an English website.
