Support
Write to support@zrspos.com with your store name and, if it concerns a document, its number (for example FS LL/1234). Include what you expected and what happened.
For SAGE-side questions (séries, document types, items), your SAGE partner is the right first contact; zrsPOS reads what your SAGE exposes.
