Happy New Year! Here are our first improvements for this year:

New product categories have been added: Electricity and Electricity resale. This enables items with the respective categories to be treated differently during tax determination, and be booked on different revenue accounts or displayed differently on pdfs.
Enabled our Webportal to easily configure tax rules that apply to customers with a VAT ID and without.
Added delayed billing to the plan config feature. Previously, all transactions from a month began to be billed at 00:00 o'clock on the first of a month. Now, you can configure billing to start at a desired time. This is useful for Usages, for example, because you may want to wait a few hours until all usages are transferred to our system, and then be billed together with all other usages of that month, instead of creating additional invoices.
Added a new configuration to our billing group where you can change which document date will be used. Currently, the document date of all documents created from orders or contracts is the date when we create the document - for example on the 1st of a month when billing the previous month.
Additionally, you can now change the document date determination in the billing group to "By Billing Period". This will set the document date according to the billing period, in our example above it would be the last day of the previous month.
Added the option to change the tax rate when editing a Line Item via our Webportal.
Fixed a bug where some Line Items could only be edited once if not yet billed.
Fixed a rare bug where termination notifications were sent out twice.
Fixed a bug where Phase Transitions weren't reset once you deleted a Phase during Plan creation.
Fixed a bug where updating a price in the confirmation stage of contract individualization didn't refresh the page to show the change accurately immediately.
Our OAS files now have a version as part of their file name to indicate changes, see here for more information
