Shopify tracks how many units you have, not which production run they came from. There is no native field for a lot number or an expiry date. Lotwise adds both. It records the lot behind every order automatically, allocates stock first-expired-first-out, flags lots approaching expiry on a threshold you set, and exports the affected orders and customer emails when a lot is recalled. Built for supplements, cosmetics, food and drink, and anything else with a shelf life.

• Automatic FEFO allocation — every order draws from the earliest-expiring lot
• Recall export — the orders and customer emails that received an affected lot
• Expiry warnings before stock becomes unsellable, on a threshold you set
• Flags units that shipped without a lot, instead of quietly losing them
• Quarantine a lot to stop it allocating, without deleting its history
