Naturacig review for Sufio: Professional Invoices

The presentation of SUFIO is a fraud, it deceives the clients and it is totally illegal. It is written: “Sufio invoices are compliant with legislation in France, the EU and over 50 countries worldwide”. It’s wrong because the invoices generated by SUFIO are not respectful of the EU tax regulation. I checked the invoices in detail with my accountant and my lawyer (specialist in tax law). The app SUFIO is not able to manage discounts on the invoices. In fact, SUFIO does incorrect calculation and shows incorrect prices when a discount is applied (the unit prices of the products are changed by the application). Up to now, I paid to use SUFIO but all my invoices (with a discount) generated by SUFIO are wrong. I have sent them a lot of emails with many details in order to find a solution. At the beginning, they said that the problem was due to the Shopify's configuration. After, they said: “this is simply how Shopify calculates prices when VAT is included. It is not something that Sufio can have any affect on.” Finally, after months, they recognized the problem and said : “our development team were actually already aware of this issue and are currently working on an update to this feature to make sure the calculation is done correctly”. They asked me to wait again months, they didn't solve anything, and they didn’t change their false presentation. I contacted Shopify support to warn them of this problem of calculation and display of incorrect prices and I am surprised that they let SUFIO continue to sell this app with a false presentation on the Shopify App Store! I have lost a lot of time, and I think it is not serious and respectful for actual and future clients of SUFIO. The sellers that are using Shopify with SUFIO are concerned. They can be controlled by the administration and suffer heavy penalties. I think these sellers are not aware about that and solving the problem quickly would have been essential.
