Our Story - Tandem Legal Bookkeeping

2010 - NIS Office

After working as a bookkeeper for a law firm from its inception through its eventual closing, Edita Milenkovic started NIS Office. At that time, cloud-based legal practice management and accounting software was giving new law firms more flexibility in how they operated.

The Vision

Edita saw an opportunity to provide specialized legal bookkeeping services remotely, giving law firms access to experienced support without the expense of a full-time, in-house bookkeeper. After earning certifications from multiple software vendors, she expanded her practice to serve law firms nationwide.

2024 - Tandem Founded

In 2024, Edita founded Tandem Legal Bookkeeping to build on the years of experience gained at NIS Office. The goal was to bring what we learned into a team environment, with a strong emphasis on technology.

We also take on the challenging work of cleaning up books that have gone off track. Sometimes, even books maintained by professional bookkeepers have years of unresolved discrepancies, reconciliation problems, or trust accounting errors that put IOLTA compliance at risk. We dig into the records, figure out what went wrong, and correct the underlying problems.

2025 - Building the Tools We Wished Existed

Over the years, we have created our own tools to make bookkeeping work easier, from simple workflow automations to moving data between systems that do not work well together. That experience eventually led us to build Tandem Dashboard, an internal application designed to solve problems we encountered in our daily work.

2026 - What's Next?

What started as an internal tool has grown into LedgerPost, a Clio-to-QuickBooks Online integration we are preparing to make available to other law firms. It gives users control over what gets posted to QuickBooks and when. We are planning a public release in late 2026.
