Mondial Relay Shipping Cost Simulator

Project in a few words

Mondial Relay publishes its rates as complex tables with dozens of columns depending on weight, destination and shipment volume. It's hard for a merchant to know what to charge customers without spending an hour on it.

This tool does the math for them: set your parameters once (margin, VAT, desired rounding), and the simulator shows the exact prices to apply in their shop.

Project highlights

• Works offline : Accessible without internet once downloaded
• Easy to share : A link or email attachment is enough, nothing to install
• Zero technical maintenance : No server to monitor, no security updates, no dependencies. The only reason to modify the file would be a change in Mondial Relay's rates
• Polished interface : Fonts embedded directly in the file to preserve the look on any device

The idea was to quickly create a practical tool that any merchant could use, easily accessible via a link and just as easily shared.
