MRP for Shopify fabricators
Run your fab shop from your Shopify orders.
BuildMRP turns every order into a parts list, tells you what you're short on, and shows the true cost of every part — from sheet to shipped. Built by a fab shop that runs on it every day.

The problem
Fab shops outgrow spreadsheets — and generic MRPs.
Spreadsheets break at 50 SKUs.
Every new fitment multiplies rows. One wrong cell and the parts list is wrong.
Generic MRPs don't know sheet yield.
They cost a part by its area, not by what a sheet of 3/16" aluminum really yields.
You find out you're short too late.
Discovering you're out of bolts after the order is due costs days and customers.
How it works
From order to shipped, without the guesswork.
- STEP 1
Shopify order comes in
Orders and variants sync automatically.
- STEP 2
BuildMRP reads the BOM
Each variant's recipe, down every level.
- STEP 3
Shortages flagged
Grouped by supplier, ready to order.
- STEP 4
Build, ship, deduct
Stock comes off automatically at fulfillment.
Shopify-native
Every variant gets its own BOM.
Two-way sync with your store. One skid plate, every fitment and material — each with its own parts list and cost.
