THE CHALLENGE

Many products, frequent purchases, and changing costs

In a hardware store, selling is only one part of the operation. Each purchase can change quantities and costs while sales keep inventory moving all day. If that information is disconnected, knowing what is available and what it really costs gets harder.

THE KRAE.OS APPROACH

Each operation updates the information it affects

Krae.OS connects purchasing, inventory, costs, and sales so that recording a movement in one part of the business automatically updates the related information elsewhere.

INVENTORY

Know what is available as you buy and sell

Krae.OS keeps inventory connected to commercial operations. Purchases add units to stock, and sales deduct the corresponding quantities, keeping product availability current.

Explore Stock and costs

How purchases and sales affect inventory

PURCHASE+ STOCK
SALE− STOCK

Inventory is not updated in a separate process. It changes when the operation that affects it is recorded.

BARCODES

Find and enter products directly with a scanner

Krae.OS lets you use barcode scanners to find and select products directly in system search fields.

When creating or editing a product, you can also scan its barcode into the product record.

Scanning helps select items in purchasing, quotes, orders, invoices, stock counts, adjustments, and warehouse transfers, among other operations.

Using a barcode scanner

  1. SCAN
  2. IDENTIFY PRODUCT
  3. USE IN THE OPERATION

Less manual searching when a product already has a barcode.

FAST INVOICING

Speed up counter sales

Krae.OS has a fast invoicing interface designed to work with a barcode scanner and receipt printer, helping staff identify products and complete counter sales quickly.

Scan to find a product and proceed directly to invoicing while Krae.OS keeps the transaction connected to inventory, the customer, collection, and SIFEN where applicable.

Recording the sale deducts the corresponding quantities from inventory.

Fast counter sale

  1. SCAN
  2. IDENTIFY PRODUCT
  3. INVOICE
  4. RECEIPT

Less manual searching. Faster service at the counter.

Each purchase updates inventory and cost

When a purchase is recorded, Krae.OS adds the corresponding quantities to inventory and uses the new purchase price to update the product's cost.

The operation stays linked to the supplier, keeping commercial and administrative information together.

COSTS

When a purchase price changes, Krae.OS recalculates cost

When new goods arrive, Krae.OS automatically recalculates weighted average cost using the existing stock and the cost of the new purchase.

This keeps cost current without arbitrarily replacing the value of units already in stock.

Automatic weighted average cost calculation

UPDATED WEIGHTED AVERAGE COST

PURCHASE AND SALES UNITS

Buy in one format and sell in another

Krae.OS lets you configure a purchase unit, a sales unit, and the relationship between them for each product.

This represents operations where the format used to buy a product differs from the one used to sell it.

Example of a configured format relationship

  1. BUY · 1 PACK
  2. CONFIGURED RELATIONSHIP
  3. SELL · 6 UNITS

MINIMUM STOCK

Spot products that need attention before stock runs out

Krae.OS lets you set a minimum stock level for each product and identify items whose available quantity has reached or fallen below it.

The minimum can be set per warehouse and globally.

  1. CURRENT STOCK
  2. COMPARE WITH MINIMUM
  3. PRODUCT TO REVIEW
  • WAREHOUSE AConfigured minimum
  • WAREHOUSE BConfigured minimum
  • GLOBALOverall minimum

See which products may need replenishment

Krae.OS lets you filter stock reports to show products with quantities equal to or below their configured minimum.

The person responsible can review those items and decide what to purchase.

From minimum level to purchase decision

  1. CURRENT STOCK
  2. MINIMUM COMPARISON
  3. REPORT
  4. PURCHASE DECISION

Manage goods spread across multiple warehouses

Krae.OS lets you manage stock in different warehouses and record movements when goods change location.

You can review quantities by warehouse, while transfers document the movement between them.

Warehouse transfer

  1. WAREHOUSE A
  2. TRANSFER
  3. WAREHOUSE B

PRODUCT → STOCK BY WAREHOUSE

Every stock movement retains its source

Inventory movements remain linked to the operations that caused them, making it possible to review how purchases, sales, returns, adjustments, and transfers changed quantities.

Source of inventory movements

  1. OPERATION
  2. MOVEMENT
  3. STOCK

SALES

Make the sale and let the system update the rest

When a sale is recorded, Krae.OS deducts the corresponding quantities from inventory and keeps the operation connected to the customer, collection, electronic invoicing, and other applicable management processes.

Explore Sales and collections

Information linked to a sale

  1. SALE
  2. STOCK
  3. CUSTOMER
  4. COLLECTION
  5. SIFEN

ONE OPERATION → SEVERAL AREAS UPDATED

A return can add units back to stock

When a sale needs to be returned through a credit note, Krae.OS can add the corresponding units back to inventory while retaining the link to the original operation.

Return through a credit note

  1. SALE
  2. RETURN
  3. CREDIT NOTE
  4. + STOCK

Keep track of what customers still owe

Krae.OS manages sales and collections within the same commercial operation, keeping outstanding customer balances identifiable when a sale is not paid in full immediately.

Sales can be paid at once or on credit, with later collections as applicable.

Sales and collections

  1. SALE
  2. CUSTOMER
  3. COLLECTION

Payment plans can be managed too

Krae.OS includes tools for managing payment plans with down payments, installments, and additional payments as part of the operation's follow-up.

Explore Sales and collections

Each collection continues into financial management

Collections recorded in Krae.OS can continue into cash register and bank management, keeping sales connected to the company's financial movements.

The system supports payment methods such as cash, transfers, vouchers, checks, and cards as applicable.

ELECTRONIC INVOICING

Invoice as usual. Krae.OS handles SIFEN.

Users complete their usual operation in Krae.OS, and the system generates the corresponding electronic documents for SIFEN as part of that workflow.

Electronic invoicing stays within the sale instead of becoming a separate administrative process.

ONLINE ORDERS

Turn your catalog into another way to receive orders

With Krae.Flux, customers can browse products in your online catalog, check prices, and place orders that continue through the commercial workflow in Krae.OS.

For a hardware store, the catalog can present more of the available range without relying solely on in-store assistance or answering one product inquiry at a time.

The catalog link can serve as a digital destination for commercial outreach, social media, messaging, and other communication channels.

An online catalog lets customers continue exploring products away from the store and can support the hardware store's digital outreach to generate inquiries and orders.

Krae.Flux connects that commercial channel with Krae.OS so received orders continue within the same management system.
