Support
Write to support@zrspos.com with your store name and, if it concerns a document, its number (for example FS A/1234). Include what you expected and what happened. When a page offers Details for support, copy them into your e-mail.
For SAGE-side questions (séries, document types, items), your SAGE partner is the right first contact; zrsPOS reads what your SAGE exposes.
When zrsPOS loses access to your Shopify store
Home shows Access to your Shopify store · Lost when zrsPOS can no longer renew its access to your store. POS sales then wait to be read; none is lost. Open zrsPOS from your Shopify admin (Apps › zrsPOS): opening the app gives the access back, and Home reads again once it has. If the row stays after that, write to support@zrspos.com.
