Veloce POS - Update and MEV-WEB overview

Update Veloce and configure MEV-WEB (overview)

Summary

This overview outlines the recommended process to update Veloce POS and prepare the MEV-WEB integration. It covers prerequisites, the update order (server then tills), firewall/network checks, and basic functional tests. Expected outcome: updated Veloce, working MEV-WEB communication, and validated test sales.

Step-by-step Instructions

1) Prerequisites

  • Windows administrator access on the Veloce server and POS stations.
  • Maintenance window (no live sales) and a recent Veloce database backup.
  • Stable Internet; antivirus/firewall exclusions for Veloce and related services.
  • MEV-WEB credentials from the authority/partner and required URLs/ports to allow.

2) Steps

  1. Prepare the update: Note current version in Veloce > About. Close tills. Backup the database and export key settings (printers, terminals, taxes).
  2. Update the server: On the Veloce server, stop Veloce services if applicable. Run the official updater and complete the wizard. Reboot if prompted.
  3. Update the tills: Start each POS station; the client update deploys automatically or via the installer. Verify version after install.
  4. Configure/review MEV-WEB: Open MEV-WEB settings in Veloce. Enter credentials and service URL, enable communication. Allow domains/ports on firewall/AV.
  5. Functional test: Open a register, create a small test sale, finalize payment (test mode if available) and confirm the MEV-WEB submission completes without error.
  6. Post-update validation: Print a receipt and an end-of-day Z (test). Confirm printers, terminals, taxes and document numbering are intact.

3) Checks and validation

  • Server and client Veloce versions match and are up to date.
  • Test sale shows successful acknowledgment from MEV-WEB (no transmission errors).
  • Printing (receipts, Z) and integrations (terminals) work as before the update.

Fixes and FAQs

  • MEV-WEB connection failure: Verify allowed URL/ports, certificates/system time, corporate proxy and credentials. Test DNS resolution from the server.
  • Version mismatch: Update the server first, then relaunch tills to pull the client update; otherwise reinstall the client.
  • Printing errors after update: Reapply printer mapping and confirm Windows drivers did not change queue names.
  • Antivirus blocking Veloce: Add exclusions (install folder, processes) and restart services.
