Free tools
Inventory tools for the work before software.
The free calculators and templates operators reach for before they buy any software. No signup, and each one does a real job on its own.
7 free resources
Each tool starts with an operator problem.
Each one solves a job you can finish today. The free result stands on its own, and Order3 is where it goes when the same work needs more than one person and a record to look back on.
Calculator
Reorder point calculator
A reorder point calculator applies the reorder point formula (average daily usage × lead time in days + safety stock) to find the on-hand level that should trigger a reorder review before you stock out. Enter your average daily usage, supplier lead time, and safety stock to get a working reorder point per SKU or location.

Safety stock calculator
Calculate the buffer stock needed when demand or supplier lead times move around. Enter maximum and average daily usage and lead time, and the calculator returns safety stock in units with the formula worked through your numbers.

Cycle count planner
Enter your total SKU count, ABC split, and how often each class should be counted. The planner converts that into required counts per week, compares it to your team's capacity, and summarizes the weekly batch.

Inventory spreadsheet template
Download a ready-to-use template with the columns an inventory system needs, plus example rows showing how to fill them in. It opens in Excel, Google Sheets, or Numbers, and gets inventory out of people's heads and into a structure you can import later.

QR code generator
Type a SKU, asset tag, or link and get a scannable QR code as a downloadable SVG. A QR holds far more than a 1D barcode and a phone camera reads it, so it suits asset tags and bin labels that should open a record. Runs in your browser, and nothing is uploaded.

Is there free inventory management software?
There are two honest free options. These tools (the reorder and safety-stock calculators, the barcode and QR generators, and the CSV templates) are free and need no account. For a live shared record rather than a one-off calculation, Order3 has a free workspace tier for small teams. Free spreadsheet templates work until more than one person updates counts or you track several locations, at which point a shared system prevents the stockouts and double orders that cost more than the software.
Are the tools really free?
Yes. The calculators and the barcode generator run in your browser with no account and no email. The templates download as CSV. Use them as much as you want.
Can I use the results in any system?
Yes. Copy a result, download a CSV, or save the template, then drop it into whatever you run today: a spreadsheet, your accounting system, or Order3. Nothing here locks you in.
What's the difference between a free tool and Order3?
A tool answers one question once: what's the reorder point for this SKU, or how many counts a week can my team protect. Order3 holds the records behind every answer: the items, locations, counts, scans, low-stock alerts, approvals, and the purchasing drafts your team acts on.
Which tool should I start with?
If stockouts are the pain, start with the reorder point calculator. If counts are falling behind, use the cycle count planner. If you're labeling new SKUs, use the barcode generator. Each one maps to a job you can finish today.
Next step
When the spreadsheet becomes the bottleneck, move the workflow into Order3.
The free tools help you calculate, plan, and clean up. Order3 turns the same rules into mobile scans, low-stock alerts, reorder drafts, and an approval history you can audit later.
