As we have been selling more and more Dynamics 365 Business Central (BC) deals this year, we had a growing need for statistical accounts inside the product, similar to what GP had called Unit Accounts (statistical accounts).
ABS, now known as Stoneridge Software has developed a free app/extension for BC to use and track statistical accounts. You can even take the statistical accounts and add them to report schedules inside Business Central to provide calculations and KPI type reporting. for Business Central lets you create, monitor, and report upon non-financial data within your general ledger accounts.
More information about their app can be found here: https://www.adv-usa.com/statistical-accounts
If you are in the need for tracking stat accounts or replacing unit accounts with BC cloud, I highly recommend their product!
