Retail Stock Management Software

While you carry a few dozen products, a spreadsheet works. As the assortment grows, trouble starts: mixed-up stock, “negative” balances, guesswork pricing, blind purchasing. You sell an item that is “out of stock”, reorder what you already have plenty of, and month-end totals never match the shelf. Each of these small failures quietly drains money from the store.

ERPJS is retail stock management software for small business — shops, e-commerce and wholesale. A product card with full history, sales, purchasing, real-time stock levels, barcodes and FIFO costing. Runs online in the browser, nothing to install. The free plan has no time limit: sign up and start keeping records today.

Product accounting in ERPJS — quick overview

What ERPJS does for your store

📇

Product card with history

Everything about an item in one place: stock by location, prices, supplier, barcodes — and the full movement history from receipt to sale.

📊

Real-time stock levels

Sold, received, transferred — the balance updates instantly. No more spreadsheet reconciliation at month end.

🔔

Reorder reminders

Set a minimum level per product — a report shows which items are running low and how much to order.

Which retail tasks does it cover?

Stock control is not just “writing down sales”. It is a chain of tasks that ERPJS connects into one system:

Sales — invoice, shipment, returns. Every sale immediately reduces stock and records who bought and at what price.
Purchasing — purchase orders, goods receipts, returns to supplier. A receipt is created straight from the order — no retyping line by line.
Pricing and margin — price lists and discounts linked to a customer. Prices can be calculated by formula from cost, so markup stops being guesswork.
Reservations — stock is reserved against customer orders: available = on hand minus reserved. Two managers can no longer sell the same unit twice.
Documents — sales receipts, delivery notes and other paperwork printed in one click.

How much do you actually earn per product?

The most common small-retail mistake is calculating margin from the purchase price alone. Real cost also includes freight, customs and defects. ERPJS calculates cost using FIFO automatically and allocates landed costs (transport, customs) to the goods received. Reports show the honest margin per product — so you can see which items feed the store and which merely occupy the shelf.

Still in spreadsheets?

A spreadsheet is a fine start: free and familiar. It breaks exactly when the business grows — two salespeople cannot work in one file at the same time, formulas drift, history disappears, and stock gets “fixed” retroactively without a trace.

ERPJS needs no download — it runs online, and the free plan costs nothing with no expiry. Import your product list from a spreadsheet via CSV in about an hour, and from then on every stock change has an author, a date and a document behind it.

ERPJS covers the full product cycle — from purchase order to sale and return — in one system. Stock, prices, margin and documents stop drifting apart across spreadsheets: everything lives in the product card.

Selling online?

For e-commerce ERPJS ships with ready integrations: orders from marketplaces are created in the system automatically, while catalogue, stock and prices sync on schedule. Stock is shared across channels — a marketplace sale instantly reduces availability for the store and the website, so cross-channel overselling disappears. Shipping and fiscal receipt integrations are available for the Ukrainian market (Nova Poshta, PRRO).

Who is ERPJS for?

A good fit:

Retail stores — from a single shop to a chain
E-commerce and marketplace sellers
Wholesale and distribution
Electronics and appliance stores (serial numbers, warranty tracking)
Businesses with several locations or warehouses

Not a fit:

Very high-volume retail (hundreds of POS receipts per minute)
Businesses that need batch/lot tracking with expiry dates (pharma, fresh food) — ERPJS does not offer this yet

How to start — 3 steps

Sign up — one minute on the registration page, confirm your email and the workspace is ready.
Import products — upload your list via CSV or enter items manually.
Opening balances — record what is currently on the shelves as your first goods receipt.

Fifteen minutes later the system shows the real picture of your store. A week later you will have forgotten spreadsheet life.

FAQ

Is the free plan really free?

Yes. The free plan works with no time limit: sales, purchasing, stock, product cards and documents. Paid features (extra users, bank and marketplace integrations) are added separately when the business grows into them.

How do I move my products from a spreadsheet?

Via CSV import: export your sheet, map the columns, and the catalogue is in the system. Current stock is recorded as an opening goods receipt. A store with a few thousand SKUs migrates in an hour or two.

Can I run several stores or warehouses?

Yes, the number of locations is unlimited even on the free plan. Transfers between them take one document, and stock is visible per location and in total.

Are barcodes supported?

Yes. Products can have barcodes attached, labels can be printed, and scanners speed up receiving and stock counts significantly.

Does it track real product cost?

Yes — FIFO costing is automatic, and landed costs such as freight or customs are allocated to received goods, so margin reports reflect reality rather than the purchase price alone.

Where is my data stored?

In the cloud with automatic daily backups. An on-premise installation is available for businesses that must keep data on their own infrastructure.
