I need to submit an extension for each cart to download sales reports.
Also needed is a standalone php script on my server to pull the reports in case the extension fails. The sales report format might differ for each cart but in general has information such as:
date, sale-status, orderID, city, state, zipcode, gross-sale, taxable sale, shipping tax, total tax, tax rate, etc.
You need to find out what is needed or available to download the reports from the following:
Etsy (both PayPal and Direct Checkout)
You might need to use cart API's to build the extension and the standalone script.
Please reply on which carts in which you are an expert. Also which cart you have submitted a live extension/plugin. Then give me bid next to each cart
