Retail software for every store and sales channel

With Composity, retailers get one system for orders, inventory, point of sale, and the online store — so a sale in the shop and a sale on the website update the same stock and the same customer.

Who this retail setup is for

Customer expectations change by season and by channel. The software has to change with them — without a second stock file for the web shop.

Inventory, checkout, and the customer in one place

How the day actually works

Staff should not ask another system whether the shelf still has the size. The till, the website, and purchasing read the same on-hand, reserved, and incoming quantities.

  • Operations & inventory

    Orders, stock, suppliers, and accounting stay together. See what each location can sell, create purchase orders before a stockout, and keep fulfillment in the same document as the sale. Details are on warehouse & inventory.

  • eCommerce

    Selling online does not mean retyping web orders into stock. Commerce and CMS & eCommerce pass the order into inventory, with promotions, discounts, languages, payments, and currencies on the same catalog. Build a store that shows what is actually available.

  • In-store point of sale

    POS is more than a cash register. The sale screen is built for touch checkout, shows purchase history, and reads live inventory so the operator does not guess. POS is included in Business OS and shares the catalog with the warehouse and the website.

  • 360° customer view

    Open a profile and see order history, previous conversations, and whether the person buys online, in-store, or from a salesperson. Sales, marketing, and support work from that record in CRM — the same customer the invoice already uses.

What you get in practice

One shopping experience, configured to the way the store already works

A unified path for the client: the product, the price, and the receipt do not change because the channel did. You still configure warehouses, price lists, and roles to match the shop — the platform does not force a single retail script.

  • One fulfillment path

    Manage products, stock, and order fulfillment together. Real-time sales and stock trends replace end-of-day spreadsheets. Business Intelligence reads the live transactions.

  • Available when the shop is open

    The service target is 99.95% average uptime, so checkout is not waiting on a local server in the back office. Data is stored in the EU.

  • A practical way off the old stack

    Teams move from another retail or eCommerce tool with help on the import. A single store can start on Go for stock and invoices; a shop that needs tills and several sites runs Business OS. See how implementation works.

Frequently Asked Questions

Yes. POS, the online store, and the warehouse use one catalog. A confirmed sale reserves quantity, so the other channel sees what is still available.

In-store POS is included in Business OS. Go covers quotes, invoices, inventory, and a mini CRM for a smaller counter that does not need a full till. The online store is Commerce, from €10/month, on the same stock.

Yes. Inventory supports multiple warehouses. Each store can sell from its own stock while purchasing and finance see the group.

Go is typically 1–5 hours for standard modules. A core Business OS setup is usually 3–10 days. A move from another platform, with history and training, is often two to eight weeks. Implementation guide.
