I absolutely cannot believe you have never been asked for single product sale export capability and that you think it is not required.
When making sales you need to see the amount of sales you have made per product and to see the proft margns. In Virtuemart I can export product sales based on a product ID and see all the profit I have made.
The issue with Hikashop is that you can't export data based on a specific product ID, so when you export sales it's EVERYTHING or nothing. If a customer has ordered multiple products the database export function only allows you to export all data and so you have to go through and remove all other product ID's and the table rows do not match, so you will have product_1 product_2 product_3 etc, and the products are in order customer adds to cart, not in product ID order. This causes endless issues.
You need to be able to simply select a product ID and export all sales for that product with the price paid, fact is my client and many other clients require this function, without being rude I honestly wish my client had not picked Hikashop as the solution because the export and sale data analysis side of the store has caused very time consuming administration issues, although you can see how many products sold, you cannot add together all the sales with cost=profit based on sale price. Same product can be sold at various prics depending on discounts, vouchers, etc. So the variables all have an impact and this helps clients to understand what products are better to offer than others and to see the margins being made.
You migt not think this is required, but it is, users need this data managment and the way Hikashop handles it, I'm sorry, but it's awful.
Don't get me wrong I like the interface and for the most part it's a pretty good eCommerce solution, we use the full system too with all the bells and whistles so when it came to exporting sales per product and we realised, you can't, my client was pretty peed off to say the least, because now instead of just exporting some data into Excel and looking at the sales (as explained) it takes literally hours to arrange the data and this also allows for human error, it's not good.
I appreciate as a developer you don't see the value in something if no-one asks, but from what I have seen searching your forum and Google quite a lot of Hikashop users have required this feature, but, if it's of no value to you you're not going to spend the time doing it.
My review for Hikashop would genuinely be:
" Amazing for a FREE version, brilliant capabilities if you get the full blown paid subscription, pretty easy to configure but if you need a solution for analysing sales, customer data and exporting data then this is not the solution for you!"
