Using Paazl SFCC cartridge and Paazl Widget will make your developer's life easier and save them a lot of time, both Back- and Front-End. Henceforth:
No need to: configure a whole bunch of Shipping method in the BM / implement multiple API calls to cover all available carriers+shipping options/ develop heavy extra code on how to display your shipping options on your site/ implement extra logic to fetch and display the correct shipping cost based on your customer's country, his address, the weight or size of his product/ implement extra logic to fetch and display the correct shipping delivery time and/or store opening hour in case store pickup delivery.
The Paazl Widget does it all for you, all you need to do is few settings on your Paazl account and one call to your Paazl API to fetch the shipping option/carrier selected by your customer This API call will return you all information you need in an XML or JSON format.
Plus the Paazl widget comes with a lot of customisable options. Most of them are directly configurable via the BM site preferences out-of-the-box with your Paazl SFCC cartridge.
One more advantage, the Paazl SFCC cartridge is compatible with both MFRA and SiteGenesis.
