Inventory Management Software For Retail

Retail inventory has one structural difference from every other kind: stock leaves the building at the point of sale, one unit at a time, hundreds of times a day, with no order document. That makes the till the primary source of inventory movement, which is why almost every serious answer in this category is a point of sale system with inventory built in rather than an inventory system that talks to a till.

We sell source code you clone and run yourself, so there is nothing hosted here. For a shop, buying a POS with inventory is nearly always the correct move, and this page is about choosing one.

Start from the till, not from the stock list

Variants are where retail data models get hard

A garment is not one product. It is a style, in four colours, in six sizes, which is twenty four sellable units that share a name, a supplier, and a season but have their own barcodes and their own stock.

Shrinkage is the number the system exists to expose

Retail loses stock to theft, damage, and mis-scanning, and the only way to see it is a count that disagrees with the record. That means periodic counting is not an administrative chore, it is the measurement.

Two practical notes. Counting a section at a time on a rolling basis is far more sustainable than closing for a full stocktake, and it catches problems while the cause is still traceable. And recording known losses separately from count discrepancies is what turns shrinkage into an actionable number rather than a single unexplained figure.

What the free and cheap options cover

Several POS products have free tiers that genuinely run a small shop, usually funded by card processing rather than software fees. That is worth understanding when comparing: a free POS tied to a payment processor is priced in the transaction fee, so compare total cost per year rather than the licence line.

Zoho Inventory and Odoo both appear in this search and both are stronger for the warehouse and online branch than for a shop floor.

When retailers build

Not the POS. Payment processing, offline resilience at the till, and receipt hardware are each a specialism and all of them are regulated or certified in some way.

What retailers do build is the layer around it: a loyalty scheme the POS does not support, a buying and allocation tool for a multi-branch chain, a supplier portal. Those are reasonable and they read from the POS rather than replacing it.

What you would start from here

There is no retail capability in this stack. No products, no variants, no stock, no till, no payments at point of sale, and no barcode handling.

What the Vault template offers for the surrounding tools is the application layer: organizations if you are serving multiple branches or franchisees, roles and invitations so a branch manager sees their own store, a Hono backend with Prisma and Kysely on Postgres, an admin app, and Stripe billing. Stripe here is for subscription revenue if you sell the tool; taking card payments at a till is a different problem with certification requirements this stack does not address.

You would write whatever the POS does not do, and read stock and sales from it rather than duplicating them. Deciding which system owns the stock number is the first architectural decision, and having two systems both believe they own it is the failure to avoid.

For the shop itself, buy a POS with inventory. The packs below are for what you build around it.
