We understand public finance.
And connect your systems.

PSG combines expertise in cash-based accounting (Kameralistik) and accrual accounting (Doppik) with data integration, reporting and interfaces. For public authorities and institutions, using the systems you already have.

Good to know

SQL Server is not a requirement.

Many of our public-sector clients use other database systems. Our work on public-finance reporting and interfaces follows your applications, data and processes. You do not need to introduce a SQL Server environment to work with us.

Typical questions

Questions public authorities bring to us.

  1. How much is still available?

    Budget, actuals, commitments and free funds per chapter and budget line: up to date, instead of after days of manual compilation.

  2. Why don't the numbers match?

    Budget, cost accounting and specialist applications deliver different states. A checked common foundation creates one number everyone can refer to.

  3. Can business units analyse data themselves?

    Anyone with a question about the use of funds should not have to ask IT. Departments and decentralised units get their own view.

  4. How can routine work become more reliable?

    Checks and calculations that live in Excel sheets today become traceable rules in the system.

Domain knowledge and delivery

From financial data to processes that work.

A report needs to answer the questions of the people using it. An interface needs to fit the process. We look at both, together with IT and the teams who work with them every day.

  1. Public-finance reporting

    Understand financial data, prepare it and turn it into reports people can follow, from the monthly report on the use of funds to views for departments and decentralised units.

  2. Interfaces between applications

    Develop and extend data transfers, investigate transmission problems and adapt interfaces as processes change.

  3. Data integration & quality

    Load data from budget, cost accounting and specialist applications regularly and with checks, with history and audit-proof storage. Origins and processing stay traceable through to the report.

  4. Reporting through system changes

    Adapt existing reports and data transfers to new sources or changed systems. Validate the results together with the teams using them.

Your domain matters

Kameralistik or Doppik? We understand both.

The concepts and relationships of public-sector accounting are part of our work. We discuss your reports in your own terminology.

Cash-based · lines & chapters

Kameralistik

  • Line-item budget
  • Budget and actuals
  • Commitments
  • Carry-overs
  • Commitment appropriations
Accrual · expenses & assets

Doppik

  • Output-based budget
  • Income statement
  • Cash flow statement
  • Balance sheet
  • Cost and performance accounting

Whether your organisation uses cash-based accounting, accrual accounting or both side by side: we bring the numbers into the form that budget, controlling and management need.

Your environment is the starting point.

  • Which applications supply the data?
  • Who works with the reports?
  • Where does a transfer between systems get stuck?

Together, we turn these questions into a focused task and a clear next step. The database is one part of that environment; useful outcomes and reliable processing guide the approach.

Experience

In public finance since the 1990s.

Consulting and software development for finance and controlling in the public sector have been part of PSG since the 1990s. Two published projects from federal and state level show what that means in practice.

    Implement and validate

    Develop the agreed change and check the results from both a business and technical perspective.
