Materials Inventory
by Material Inventory, Inc.
A Shopify app for makers that tracks raw materials against product recipes, deducts them as orders come in, runs production batches and raises purchase orders. Manufacturing orders start on the $89 Business plan. There is no public documentation beyond the landing page and the App Store listing.
Why it is classified this way
We call this a Light manufacturing product. Has bills of materials or recipes, consumes stock when you build, and tracks production, but time-phased planning is not verified.
It is not labeled Full MRP because we have not verified that it represents a bill of materials, recipe, or formula; accepts dated demand, sales orders, a forecast, or a master production schedule; nets that demand against stock on hand and orders already incoming; explodes requirements through at least one level of the bill of materials; uses lead times or required dates; and produces dated buy, make, transfer, release, or reschedule recommendations. That is a statement about the evidence we found, not a claim that the product is weak, see the capability table and the sources below.
The six Full MRP tests, and how Materials Inventory does on each (0 of 6)
- PartialIt represents a bill of materials, recipe, or formula.Not established. Backed only by a limited source (a vendor video from before 2023, source code, an old blog post or a single marketing line), which can fill the table but cannot pass this test.
- UnknownIt accepts dated demand, sales orders, a forecast, or a master production schedule.Not established. No evidence found yet.
- PartialIt nets that demand against stock on hand and orders already incoming.Not established. Only partly shown: the evidence covers some of this but not all of it, so the test is not established.
- UnknownIt explodes requirements through at least one level of the bill of materials.Not established. No evidence found yet.
- PartialIt uses lead times or required dates.Not established. Only partly shown: the evidence covers some of this but not all of it, so the test is not established.
- UnknownIt produces dated buy, make, transfer, release, or reschedule recommendations.Not established. No evidence found yet.
These rules are applied identically to every product and enforced at build time, a record cannot be published as Full MRP unless all six pass with a source attached. Read the methodology.
Best for
- Shopify makers whose product stock depends on raw-material stock
- Small shops that sell kits and bundles and need component stock kept in sync
Not a fit when
- Anyone not selling on Shopify: the app runs inside a Shopify store
- Shops that need lot tracking, quality records or dated purchase planning, none of which is described
