Replenio runs your full purchasing loop inside the Shopify admin. The Reorder Dashboard turns sales history into clear reorder decisions: days of stock left, when to reorder, and how much, based on each supplier's lead time and minimum order. Build POs from your catalog, email branded PDFs to suppliers, and receive by barcode. Recalculate unit costs with FIFO or weighted costing. Switching from a retiring purchasing app? CSV import rebuilds suppliers, unit costs, and reorder points in minutes.

• Reorder dashboard: velocity, days of cover, order-by date, suggested qty
• Auto-generated POs when stock runs low, plus Shopify Flow triggers
• Receive by barcode scan — partial deliveries, damaged units, auto sync
• FIFO or weighted inventory valuation with freight and duty allocation
• Supplier records with CSV import — switch from a retiring app in minutes

Backordr manages everything that happens after a customer buys an out-of-stock item. Show "On backorder — expected by [date]" on product pages, split mixed carts so available items ship now while backordered ones wait, and let FIFO allocation auto-fulfill orders the moment stock returns. Includes a backorder dashboard, automated customer emails, and a Google Merchant Center feed that keeps restock dates in sync. Works with Shopify's native fulfillment tools — no theme edits.

• Show expected restock dates on your product, collection and cart pages
• Ship the in-stock half of a mixed cart without waiting for the rest to arrive
• Fill returning stock against the earliest orders first, without you touching it
• Send branded backorder, restock-date and shipped emails to your customers
• Collect emails on sold-out products and notify that waitlist when stock lands
