Business system 2026

The paper records are gone. One central warehouse, run from a phone, sells on four websites at once — and every one of them works from the same stock.

A tyre, wheel and car parts retailer that took paper out of its warehouse and now runs stock from a phone — with one central warehouse selling on four websites, and stock tracked across all of them.

From paper to phone

The paper is gone. The warehouse runs from a phone.

Warehouse records used to be kept on paper and in spreadsheets. Now the work is recorded on a phone as it happens: scan a barcode, or photograph a label or a tyre sidewall, and the item comes up, ready to sell on the spot. If the signal drops, the sale is kept and sent when it returns.

  • Before: Warehouse records on paper Now: Goods received or taken off stock from the phone, with every movement on record
  • Before: Spreadsheets out of step between locations Now: One stock figure, with the amount held at each location on the item's screen
  • Before: Seasonal tyre storage in notebooks Now: Each stored set booked on a phone, against the customer, the vehicle and its place in the warehouse

One warehouse, four websites

One central warehouse. Four websites. The same stock behind them all.

Krajina Auto sells on its own main shop and on three partner sites. Items, prices and stock all start from the central warehouse, so nothing has to be entered four times.

  • Entered once

    A new item goes into the warehouse once and reaches every website it belongs on.

  • Each website its own price

    Every website has its own price list, and having a price there is what publishes an item.

  • No stock, no sale

    When an item runs out, the websites follow: it is marked out of stock or the listing comes down.

Staff & working hours

A card at the warehouse door. The hours add themselves up.

Every worker has their own access card for the warehouse. Each day goes on the record as it happens, so the month no longer has to be pieced together from paper.

  1. Shift starts with a card

    A tap of the card when the worker arrives signs them in to their shift, and the exact time of arrival is kept.

  2. Shift end on the same record

    The day is closed on that same record, checked against the shift the worker was scheduled for.

  3. Breaks included

    Each working day carries its break, so time at work and time worked are kept apart.

Accounting gets the full picture

At the end of the month, the employee working-time record is created from what is already there, for each worker, and printed ready for signature.

01 Business context

Krajina Auto sells tyres, alloy wheels and car parts across several locations and four websites. What used to live on paper, in separate programs and in spreadsheets now runs on one system.

The business sells at the counter, through its own shop at krajina-auto.com, and through wheels.ba, OLX and Njuškalo. Every one of those channels needs the same item, the right price and an honest stock figure — and every one of them used to be updated by hand.

Now the central warehouse is the single source of truth. An item entered once appears on the websites it belongs on and in the staff app, at the price set for each channel. There is no second entry, and no conversation about why the website disagrees with the counter.

01 Each category carries its own attributes — tyres by width, profile, diameter and season; wheels by diameter, bolt pattern and offset — and new kinds of goods are added without development work.

02 The challenge

Nothing was broken on its own. Every part of the business simply kept its own version of the truth — and keeping them in line was manual work.

  1. 01 Warehouse records kept on paper and in spreadsheets that were never in step between locations
  2. 02 A web shop updated by hand, with prices and stock days behind
  3. 03 Online listings written and taken down one at a time
  4. 04 Invoices typed up by hand, with numbering kept in someone's head
  5. 05 Working hours on paper, added up by hand at the end of the month
  6. 06 Seasonal tyre storage recorded in notebooks

03 The solution

One catalogue, one stock ledger and one set of rules — reached from the office, from the warehouse floor and from every sales channel the business uses.

Stock is recorded as individual movements rather than a running total, so every figure can be traced back through its history instead of simply being trusted.

Each sales channel has its own price list, and having a price there is what publishes an item. Nothing goes public by accident, and nothing is forgotten.

Invoices, proformas, delivery notes and quotes are issued with automatic numbering, discounts and VAT, ready to print and send.

02 An item's full detail on a phone: price, stock by location and specification, from anywhere in the warehouse.

04 Key capabilities

What it makes possible.

  1. 01

    One catalogue behind every channel

    An item entered once reaches krajina-auto.com, wheels.ba, OLX, Njuškalo and the staff app, each at its own price. No duplicate entry, and no price that disagrees with itself.

  2. 02

    Stock you can explain

    Every receipt, sale, correction and return is recorded with who made it and why. The current figure is the sum of its own history, so a difference can be traced rather than argued about.

  3. 03

    The warehouse in a pocket

    Staff scan a barcode, or photograph a label or a tyre sidewall, to find an item and sell straight from the phone. If the signal drops, the sale is kept and sent the moment the connection returns.

  4. 04

    Working hours that add themselves up

    Staff sign in to their shift with a card at the warehouse door. Shifts, holidays, leave and sick days roll into the monthly hours automatically, and the record prints ready for signature.

  5. 05

    Seasonal tyre storage, properly recorded

    Each stored set is logged against the customer, the vehicle and its place in the warehouse, with a pickup date and a printed receipt — booked at the counter or on a phone next to the customer.

  6. 06

    Customer messages that reach a person

    A visitor writing from the website appears in the system and on staff phones immediately, along with the page they were looking at — so the answer is about the right product.

05 Business value

What changes for the business.

  • No more paper in the warehouse: the work is recorded from a phone, where it happens.
  • One central warehouse behind four websites, with the same stock behind all of them.
  • Listings and prices that update themselves instead of waiting for someone to remember.
  • A month end that is printed rather than pieced together.

From paper records to a phone in the warehouse, and from one central stock to four websites — one system, one set of figures.
