@cketelaar @MissTipsi I agree on the flexibility and in some ways lack of calcualtions. I was expecting the term length to affect the Net Price i.e. Unit Price is £100 annually, sell this product to a customer for a Term of 3 months, the Net Price is £25. However, as it stands, the term has no effect on the Net Price, meaning the Unit Price has to be manually calculated.
This would be the same for longer term deals. You need the term length to affect the Net Price and thus then affect the Total Deal amount if I am reading your requirements correctly.
