README

Magento Inventory (MSI) support for ZERO-1 OpenPOS.

OpenPOS on its own works with Magento's legacy stock handling. Install this module on stores where Magento Inventory (MSI) is enabled, so till sales update stock levels:

composer require zero1/open-pos-msi
php bin/magento setup:upgrade

What it does

• Till sales deduct stock. OpenPOS orders are virtual, so they are never shipped and MSI never deducts them from a source. This module deducts the items from the shop's source when a till sale is placed, and closes MSI's reservation for the order.
• Layaways are deducted when they are fully paid, or when they are placed (see configuration).
• Cancelled layaways that were already deducted have their stock put back.
• Credit memos with "Return to Stock" put till sale items back on the source they were deducted from.
• Bypass stock checks works under MSI: when enabled, the till can sell items MSI considers out of stock. If a source holds less than was sold, it is reduced to zero.
• Returns (OpenPOS RMA) no longer reduce stock or fail for out of stock items. As without MSI, returned items are not added back to stock.
