What the CRMiUS warehouse management system does

A warehouse management system records what is in stock, in which warehouse, and how it moves. In CRMiUS it is a CRM module: stock per item and warehouse changes only through documents — receipts, delivery notes, transfers, inventory counts. Invoices create delivery notes and received purchase orders create receipts, so sales, purchasing and the warehouse share one set of numbers.

  • Several warehouses, each with its own balance, and transfers between them
  • Goods receipts and delivery notes with a movement history for every item
  • Minimum and maximum stock per item with a reorder alert
  • Serial numbers and expiry dates on the items that need them
  • Inventory counts that post the difference as a document

Price: plans from $100 a month (Basic), Advanced $150, Corporate priced individually; 10% off with annual payment. Which modules you need, warehouse included, and which plan covers them, we clarify in the demo. 14-day free trial, no bank card. Compare plans

How stock moves through CRMiUS

Every arrow below is a document someone can open later. Quantities change only at the receipt and the delivery note; the reorder alert closes the loop back to purchasing.

Stock flow in CRMiUS Purchase order → goods receipt (+ stock) → customer invoice → delivery note (− stock) → minimum reached → next purchase order. 01 Purchase order sent to the supplier from the purchasing module 02 Goods receipt quantities added to the chosen warehouse + stock 03 Customer invoice the manager sees availability by warehouse 04 Delivery note created from the invoice, cost of goods goes to finance − stock 05 Minimum reached alert to the buyer: time to reorder reorder

Inventory in real time

Every movement is a document you can open

Balances on the screen are the sum of receipts, shipments and transfers, so a number always has an explanation.

  • Goods receipt notes from suppliers with cost and quantity
  • Delivery notes generated from customer invoices
  • Transfers between warehouses with sender and receiver
  • Inventory counts that post the difference as a correction

What your team does in the warehouse module

  • Keep one item catalogue

    Products and services share one list with SKU, units, prices and taxes, used by sales, purchasing and the warehouse.

  • Run several warehouses

    Each warehouse holds its own balance; a transfer moves stock between them with a document on both sides.

  • Receive goods

    Record a goods receipt against a purchase order or as a standalone delivery from a supplier.

  • Ship to customers

    Create the delivery note from the invoice so stock leaves the warehouse when the sale happens.

  • Control minimum and maximum levels

    Set thresholds per item and get an alert before a shortage or when stock piles up.

  • Track serial numbers and expiry dates

    Record them on receipt and see which unit went to which customer.

  • Count stock

    Run an inventory count, compare it with the system balance and post the difference.

  • Read movement reports

    Stock on hand, movements by period and item history for planning purchases.

Warehouse management for a small business: the five operations

Small-business warehouse work comes down to five operations. Here is where each one lives in CRMiUS.

  • Receiving. A goods receipt against the purchase order adds quantity and cost to the chosen warehouse.
  • Storage. Each warehouse has its own balance; transfers move goods between locations with a document.
  • Shipping. The delivery note comes from the customer invoice, so stock leaves when the sale is made.
  • Inventory. A count compares the shelf with the system and posts the difference.
  • Replenishment. Min/max thresholds per item trigger a reorder alert for the buyer.

A CRM with a warehouse, or a separate WMS?

A CRM with a built-in warehouse suits a trading business whose warehouse serves sales: wholesale, shops, an online store, small production. A large distribution centre with bin-level addressing and handheld scanners is usually run in a specialised WMS. If your process is closer to that, show it to us in a demo and we will tell you plainly which part CRMiUS covers.

Getting started: we set up your warehouses, import the item catalogue and opening stock from a file and set the reorder thresholds. Module configuration and team training are available as CRMiUS services.

Who uses it

  • Wholesale distributors

    Several warehouses, large catalogues, transfers between locations and supplier orders from procurement management. See CRM for wholesale distribution.

  • Retail chains and shops

    Stock per store with the POS module selling from the store's balance — see CRM for retail.

  • Online stores

    The invoice for a web order creates the delivery note and the parcel leaves with a document — see CRM for online business.

  • Small production

    Raw materials received, finished goods stored and shipped; the manufacturing module (bills of materials, work orders) runs on top of warehouse and purchasing. See CRM for manufacturing.

Questions and answers

What is a warehouse management system?

A warehouse management system (WMS) records what is in stock, where it is stored and how it moves in and out. In CRMiUS the WMS is a module of the CRM, so receipts, sales and purchases update the same balances.

Can CRMiUS manage several warehouses?

Yes. Each warehouse has its own balance, and transfers move goods between them with a document on both sides.

Does CRMiUS track serial numbers and expiry dates?

Yes. Serial numbers and expiry dates are recorded on receipt and stay attached to the item through delivery.

How does stock change when we sell?

A delivery note created from the customer invoice takes the items out of the selected warehouse, so stock follows actual sales.

How much does a warehouse management system for a small business cost in CRMiUS?

Plans start at $100 per month (Basic); Advanced is $150, Corporate is priced individually. Annual payment gives 10% off, and from 10 users terms are individual. Which modules you need, warehouse included, and which plan covers them, we clarify in the demo.
