Amazon FBA Invoice - Use Fulfillment Date as Invoice Date in CIN7

CIN7 Core uses the "order date" in Amazon even though our system is setup as “Fully Shipped Sales”. This causes problems on the bookkeeping, especially when the sales order is from previous months that have already been closed. We have seen the orders dated many months in arrears, when clearly the order is shipped today from Amazon. 

Could you please check if you can access the “fulfillment” date from the Amazon API and use this as the “invoice” date which would create proper accounting for a company that sets up the sales integration as “Fully Shipped Sales”. 

Thanks,

Emma
