Hi Jerome, I have always test sites/copies of the current sites so you are always more than welcome to have a look there:
In general: setup is in Euro's no other currencies.
When I do a simple test like trying to show all completed orders from 1/1/70 to 1/1/2025, no VAT and nothing else selected, basically showing the total of all complete orders I get in the dashboard: 39.405,78 as total ( yes note the comma, )
When I export the completed orders (love that mass action option) and run a total in Excel, I get: 32263,10997
When I check the amount of orders in the dashboard versus excel, I get the exact same amount. In this case 207.
Other test: Set the order total for this month (5 orders confirmed), dashboard shows 6 orders for this month and the total but there are only 5 confirmed. Total in excel is 594 and dashboard shows 1720.66. Doesn't matter if I set the date fixed or choose the preset for this month. Een when I add a sixth order it still does not add up to that total.
This is consistent through multiple sites.
I have checked for wrong entries but there are no refunds (yet) on that site, all incomplete orders are removed, no shipping so all pretty straight forward.
Let me know if you want access to one of the sites and where I can mail the details or if I can do any additional checks.
