RE: BC On-Prem - Web shop / e-commerce
Sana does the implementation. But you need to go to your partner then they will send you to Sana and Sana does the implementation.
I think at base you are looking for 70k-90k (license for first year + Implementation) and if any "customization" require then you are looking for T&M charge. Sana does not provide hourly charge. it is a daily charge for a full day. Keep in mind after that it is monthly charge to maintain the Sana. If you need some add-on for Sana those are extra charges.
Also, it is not a true cloud service (similar to BC SaaS). They have a brand new installation for each customer ( included in licenses ). They will manage that host for you and that is included in monthly cost.
