ShelfRestock helps small Shopify stores decide what to reorder and how much. Every suggestion shows its math: sales speed, supplier lead time and stock on hand. Send purchase orders, receive shipments in parts, and keep a dated cost history so earlier costs are not overwritten. Track supplier invoices and due dates in one place, and get a weekly email that keeps the list handy. It is built for stores that have outgrown spreadsheets.

• Explainable reorder suggestions — the exact formula is shown for every number.
• Dated cost history — each delivery keeps its unit cost and weighted average.
• Supplier payables — invoice aging buckets show what you owe and when.
• Weekly email digest and stockout alerts, in your store's timezone.
• CSV export for reorder lists, purchase orders, cost history and aging.
