"Seamless Single Integration with Flexible White-Label Flow and Hands-On Support"

5/5

What do you like best about Maesn?

One integration instead of many. As an example, the DATEV's OAuth complexity is absorbed and the integration becomes seamless. The white-label flow allows for a needed flexibility. Responsiveness and flexibility. Co-founder-level engagement from first contact, weekly call, dedicated Slack channel, and they put a new connection on the roadmap for our specific special needs.

What do you dislike about Maesn?

We're happy with the choice with made as it had more pros than cons. What we evaluated was the speed to market and flexibility of the single integration, versus the fact that we'd be dealing with a single point of failure for every accounting connection. The unified API doesn't eliminate all per-system variations, but we still found it very valuable especially when combined with the MAESN expertise and guidance on the specific per-system implementations.

What problems is Maesn solving and how is that benefiting you?

German SMEs had no automated way to get their Holvi data into the software their tax advisor uses. The workflow was manual CSV export. In Germany accounting software integration is standard practice, tax advisors typically expect data flowing into DATEV or similar, and some of the competitors already offered it. One MAESN integration allows us to reache DATEV, Lexware Office, sevDesk and many other accounting software quickly increasing our market coverage. Review collected by and hosted on G2.com.
