How it works

From your POS to the tax authority, end to end

Westpower VMS SDC sits quietly between your POS and the tax authority. Each receipt is checked, signed using the tax authority's smart card through a secure reader, and forwarded to the authority the moment it is issued.

Westpower VMS SDC covers that requirement — officially accredited, cross-platform (Windows, macOS, Linux), and priced to stay within reach.
