What Is an Inventory Tracker?
An inventory tracker is a running record of everything your business holds: each product, how many units you have, and every movement in or out. Every time stock arrives, sells, gets used, damaged or recounted, you log a stock movement — and the tracker keeps the live count, flags what's running low, and shows the full history per product. This guide is part of our Business & Invoicing Hub, home to every free business tool we make.
Small shops usually start with a notebook or a spreadsheet. Both work until the day you sell something you thought you had, or reorder something you already had plenty of. An inventory tracker replaces guessing with a number you can trust.
Why Track Inventory at All?
- Never oversell. Selling stock you don't have means refunds, bad reviews and lost customers. Live counts prevent it.
- Stop over-ordering. Money tied up in dusty shelves is money not working. Order what you need, when you need it.
- Catch shrinkage. Damage, loss and miscounts show up as adjustments in the movement log — patterns become visible.
- Reorder before the gap. Low-stock alerts mean you restock before the shelf is empty, not after the complaint.
- Know your winners. Movement history shows which products actually move — that's your restock priority list.
How to Use PaxmaHub's Free Inventory Tracker
- Open the free app. Click "Try the Free Tracker" above — instant, no signup.
- Add your products. Name, category, starting quantity. Add SKUs now or later — names alone work fine to start.
- Log stock in. New delivery? Record it as a stock-in movement with the quantity and supplier.
- Log stock out. Every sale or use gets a stock-out movement. The count drops immediately — no negative stock allowed.
- Watch the dashboard. Low-stock flags, recent movements and product totals update live with every entry.
The free version covers up to 10 stock movements — enough to run a real product through receive-sell-reorder and feel the system working. The full version on Etsy removes the cap for busier shops.
Sell services too? Pair this with our free invoice tracker — stock on one side, billing on the other, and your whole small business is covered.

Paid inventory software is built for warehouses with teams — barcode scanners, multi-location, purchase orders. If that's you, you already know it. For a small shop, that power is overhead. A free inventory tracker gives you the 20% of features that prevent 80% of stock problems: counts you trust, alerts before gaps, and a history that explains itself.
5 Stock Habits That Prevent Headaches
1. Count what you have before you start
A tracker is only as true as its starting numbers. Do one honest physical count, enter it, and everything after is arithmetic.
2. Log movements the same day
A sale logged tomorrow is a count that's wrong today. Same-day entries keep the dashboard honest.
3. Set reorder points early
Don't wait for zero. Decide the "order more" level per product (lead time × daily sales + buffer) and respect the flag.
4. Separate damage from sales
Log damaged or lost stock as adjustments with a note, not as sales. Your margins — and your reorder math — depend on the distinction.
5. Review slow movers monthly
Products with no movements for 60+ days are shelf rent. Discount, bundle or discontinue — decide with data.
When Should You Upgrade to Paid?
When 10 movements feel cramped — you're logging daily and the cap interrupts your flow — the full version on Etsy removes the ceiling. Until then, the free inventory tracker runs the complete receive-sell-reorder loop.
How to Choose the Right Inventory Tracker
- Speed test: can you log a stock-in in under a minute, phone in one hand, boxes in the other?
- Truth test: does it block impossible states (like negative stock), or let errors pile up silently?
- Alert test: will it tell you stock is low, or do you have to go looking?
- History test: can you see every movement on a product — who, what, when — for disputes and audits?
Frequently Asked Questions
Is this inventory tracker really free?
Yes. The free version runs in your browser with no signup and no cost, for up to 10 stock movements. The full version on Etsy removes the limit.
What counts as a stock movement?
Any change to a product's quantity: stock in (purchases, returns), stock out (sales, usage), and adjustments (damage, recounts). Each is logged with a date and note.
Do I need SKUs to track inventory?
No — SKUs help as you grow, but the tracker works fine with plain product names. Add SKUs when you pass ~30 products.
Does it warn me about low stock?
Yes — the dashboard flags products running low so you can reorder before you run out.
Does it work on mobile?
Yes — it's a responsive web app, handy for stockroom counts on your phone.
Can it handle suppliers too?
Yes — save suppliers alongside products so every stock-in movement knows where it came from.
