Sorry for the delayed response. Me and some of the SureCart team were attending WCUS in Portland last week.
We are going to work on real time rates even though we don’t get the request that often.
SureCart is architected for merchants that value reliability, performance, and profits. The way our system is designed, there is a platform component to ensure speed, security, scalability, and reliability.
From the plugin description page here:
Platform Based
There are two parts to SureCart, the platform, which is the Ecommerce engine, and the plugin.
The platform is built with the same technology that Shopify, Basecamp, GitHub, Twitter, Stripe and more use. These are all multi-billion dollar companies.
The plugin connects to the platform in real-time, taking all the load away from your website and onto our platform that was built and optimized for Ecommerce.
This way you get everything you want with none of the stuff you don’t want. SureCart will not slow down your website, it won’t bloat your database, it’s less likely to have plugin conflicts, and it’s made to work with your caching setup. But the real benefit here is you get assurance and peace of mind because you don’t have to worry about security, storage, or backups.
