Know what to reorder, and what it really costs
Spike turns your actual sales into a reorder quantity for every variant, then follows the stock all the way to the shelf: purchase order, delivery, freight and landed cost.
- A sales rate that is not distorted by being out of stock. Days a variant was unsellable are excluded from its rate, so an item that sold out is not mistaken for an item nobody wanted. Stock already on order is subtracted, so the same delivery is never ordered twice.
- Purchase orders your supplier can act on. Draft against suggested quantities, respect the minimum order quantity and case pack they actually enforce, and issue a PDF. Editing an order that has been sent raises a new revision rather than quietly rewriting the one they already have.
- Landed cost, not just the invoice price. Freight, duty and handling are allocated across the units you kept — by value, by quantity or by weight — to the cent. The result becomes a weighted-average cost history you can read back, and it is written back to Shopify so your margins there use the real number. Buying in another currency? Enter the rate from the invoice and the landed cost is converted first.
- Receiving that tells you when something did not land. Stock recorded here but not yet in Shopify is retried automatically, and anything that cannot be resolved safely is reported rather than guessed at. Stock you have paid for should never be invisible.
