# Sync Data of Location and Inventory

Before utilizing the Pickup Delivery Date app, it is necessary to synchronize data related to locations and inventory. This ensures our system accurately calculates the availability of items for various shipping methods.

We offer two areas for you to synchronize data  

1. Initial installation process

On the configuration page, if you notice incorrect data, you can click the 'Resync' button for the specific entity that requires correction.

If the 'Resync' button does not resolve your issue, please contact us via email at [hello@letme.pro](mailto:hello@letme.pro) or through [Live Chat](https://tawk.to/chat/6526a95deb150b3fb9a067f0/1hcfgb608) .
