Is the "Subscription products" a good option to sell access to platform through a subscription model?

Hi, I`m starting a business where I´m offering software to manage certain business, the software is accessed through any browser and the idea is to require a monthly payment to keep having access to the product (I wouldn't be delivering a new product each month). After viewing the options offered by Squarespace I think the option of "Subscription products" is the thing that comes the closest to what I need, but in the page where it's described it doesn't mention selling software anywhere. So I was wondering if this is the correct use of that product. Also if this product is indeed what I need, I was wondering if there's any API or something that I could use to access the data showing which customers paid and which customers didn't, to connect it to my MYSQL database and automatize the whole thing. Thank you in advance.
