So in my last rant I mentioned an ERP. This is its story:
When I started, all paperwork (including invoices, delivery slips, orders to suppliers etc.) was done on Word and some Excel, no specialised software whatsoever.
At some point (I already worked there for 2 years then), it became too much even for our boss, so he decided to spend some cash on the real deal.
After some looking around, he found software that seemed right (same vendor as our external bookkeeper used, so it would work with him too, nice). In order to save some money, he purchased it in Germany, as they offered a smaller product costing way less (we were based in Switzerland).
Once installed, we realised that this product was only meant to be used within the EU, as it only supported € as a currency and German VAT rates. We needed Swiss Francs and local VAT to work as well.
His solution looked as follows: I had the task to edit all forms via built-in MS Report Builder (god does it suck) to display the string CHF instead of €, and alter the on-sheet excel-like functions to use our VAT rates. Internally, the application of course still thought it was using € etc. For that reason, all output was unusable for bookkeeping, so we (as before) would just hand it in on paper.
If he had purchased the version sold here, all of the above would not have been the case, meaning support for multiple currencies and VATs, as well as direct transfer to the bookkeeper. He hardly saved 15k, in exchange for a non-working solution.

Fuck SSRS!
Fuck rsweb:ReportViewer!
Fuck MS Report Builder!
Fuck the people on the internet that made this all seem like it was feasible and easy!
