Just In Time Order Builder

Free Just In Time Inventory Order Builder

If you’re trying to run just-in-time purchasing or want to hold high value inventory close to zero, then this tool helps you calculate what to order—fast and with efficiency.

It’s built for the real-world workflow where:

• You already know the amount of material you need for upcoming jobs (Required)
• You check what’s physically on the shelf (On-hand)
• You deduct what’s already been committed (Reserved)
• You apply a wastage allowance (Wastage %) to account for shortages, errors and a tiny amount for safety stock levels

Use the starter tool below to generate your next optimised order for 4 items in minutes and start to reduce the cash tied up in your business

How the Builder Works
This Starter Edition uses a simple, robust method:

• Available Stock = On-hand − Reserved (never below zero)
• Net Required = Required − Available (never below zero)
• Order Quantity = Round Up(Net Required × (1 + Wastage %))

This is ideal if you’re:

• Running project-based work (fabrication, installation, joinery, construction) and want to order what is necessary
• Routinely ordering raw materials weekly/fortnightly/monthly
• Wanting a simple way to keep cash tied up in stock optimised without risk exposure to shortages

This Tool Is For

• Small manufacturers and workshops
• Trade businesses with job-based purchasing
• Ops managers keen to reduce over-ordering
• Owners who want a lightweight planning tool without an expensive ERP

Want This Across Your Business?
This tool has intentionally been kept simple, but Stageworks Consulting can turn this into a lightweight system that connects:

• Job requirements → purchasing → supplier lead times
• Inventory reservations by job
• Simple approvals
• Excel / SharePoint Lists / workflows
