Visual Mesa Production Accounting, formerly S-TMS Production and Yield Accounting, provides a complete state of the art solution for production accounting and data reconciliation which supports mass loss detection initiatives in complex industrial environments. It serves as a:

  • Productivity tool for the pumpers to log their activities while providing early error detection when reporting movements and inventories.
  • Data preparation tool for data reconciliation and analysis.
  • Central data repository where inventories and movements are calculated, distributed, traced, stored and checked using a rigorous model of the entire plant including tank farms or business unit.
  • Mass balance reconciliation tool, both global and by components.
  • Gross error and mass loss detection analysis tool.

VisualMesa Production Accounting supports the implementation of production / yield accounting and data reconciliation best practices. In addition, it provides an auditable work environment for the Yield Accountant.
