The formula is short: every line is zero, and a sum of zeros is zero. Slide the users to 250,000, the systems to 50 and the support tier to Enterprise Plus - the sheet does not move, because nothing is counting. abap2UI5 is [MIT licensed](/resources/license), commercial use included, and an app built with it is a standard UI5 app served by the ABAP stack you already run. ## What is not on the sheet Two things, and they are the same for any ABAP program: the SAP license you already have, and the time of whoever writes the app. Both were yours before abap2UI5 and stay yours with it. ## The one line that is not zero abap2UI5 is open-source work. The people who build and maintain it do so in their free time, and the zero above is what they give away. If this page just took a budget line off your project, consider giving a little of it back: [sponsor the contributors](/resources/sponsor), and the open-source projects abap2UI5 is built on.
