Hi, normally people ask this directly to us but maybe good to have a public answer here; thank you for your interest ->
1, if you pay by normal invoice there is no booking fee (and via nexus without need for us to complete additional paperwork etc. which requires service levels in addition, see also in Nexus); You can prepare an official quotation yourself (just put in your cart what you need and then go to print quotation); an invoice will be sent after you have placed the order. VAT is applied only for orders within Germany or for orders from Europe without a valid VAT number (which must be entered in the user profile).
2, for ecoinvent and this license type, the number is unlimited.
3 the license is typically within one department, not across several departments
4 no, IPs are not limited, as openLCA is a desktop software that works also without internet; users need to commit to the respective license before downloading though.
Let us know if you have further questions, thank you!
Andreas
