Inventory Management for Aluminum Fabrication: A Complete Guide

Ask a fabrication shop owner where the money goes and they'll point at the cutting room. Ask where it quietly leaks and they'll point at the stock room. Aluminum profiles sitting in racks, offcuts piling up beside the saw, reorder decisions made from memory — inventory is the silent cost line in every aluminum factory, and the hardest one to see clearly.

The difference between a profitable shop and a busy one is rarely cutting speed. It's how much metal is tied up in stock, how much is turning into offcuts, and how often the line stops because a profile ran out. This guide compares the two ways to run it: the manual method most shops grow up with, and the automated approach WindowCraft Pro puts on the shop floor — task by task, with the numbers that matter.

The Comparison at a Glance

Here is the same week of inventory work, run two ways. Every row is a task your team already does — the only question is how.

Feature by Feature: Where Manual Inventory Breaks Down

1. Stock takes that take minutes, not days

The manual stock take means shutting down the floor, counting racks, and reconciling against a spreadsheet that drifted the day it was written. In WindowCraft Pro, every order cut and every delivery received updates stock automatically. A stock take becomes a spot-check of one profile family, done between jobs — the numbers already agree.

2. Reordering before the line stops

Manual minimum stock is a number in the buyer's head, and a busy week skips it entirely — until the line stops at 10am because a 70mm profile ran out. With WindowCraft Pro you set a reorder point per profile; when stock drops below it, the system flags it and suggests a quantity based on recent consumption. The emergency call to the mill disappears.

3. The offcut pile, finally searchable

A 60cm offcut of a standard profile is worth real money — but only if someone knows it exists. When the saw cuts in WindowCraft Pro, the offcut is logged with its profile, length, and finish. Your estimator checks offcut stock before ordering new metal, and a reusable piece gets allocated to the next order instead of rebought at full price.

4. Consumption that follows the cutting list

Manual stock records say what was bought, not what was used — and the gap between the two is where over-ordering and waste hide. In WindowCraft Pro, each order allocates the profiles its cutting list consumes, so stock levels move with real production. Over-ordering shows up the day it happens, not the month after.

5. Live numbers for the owner

Under the manual method, the owner hears about stock problems at month-end, when the money is already spent. The WindowCraft Pro dashboard shows cash tied up in stock, slow movers, and material cost per order at a glance — the answer to “how much stock do we have?” is seconds away, without walking the floor.

Measured Results

Beyond Raw Speed

• Fewer stockouts: reorder triggers turn “we ran out” from a weekly event into a rare one — and a stopped line costs far more than the profile that would have prevented it.
• Offcut reuse: every offcut reallocated to an order is metal you did not buy, at full margin.
• A cleaner audit trail: receiving, consumption, and despatch are recorded automatically, so the numbers reconcile without a chase.
• Owner visibility: stock, WIP, and material cost per order are visible live — the stock room stops being a black box.

Who Benefits Most

Getting Started Without Stopping Production

• Week 1: load the product catalog and opening stock counts for the profiles you actually cut.
• Week 2: pilot on one profile family — receive, cut, and reuse it inside the system.
• Weeks 3–4: roll out to the full shop; the floor scans receiving and the office stops re-keying.
• Then measure: run the first stock take against the new live numbers and compare them with last quarter's paper count.
