Owned Business Case Study
Čajanka connects its webshop to the business behind it.
This is not a story about one isolated redesign. It shows a system connecting shopping, orders, accounting, stock, suppliers, partners, and the decisions a retail business makes every day.
Visit Čajanka.hrBusiness context
The webshop is the entrance to an operating system.
A customer sees products, content, and a straightforward path to an order. Behind that, the team must align the invoice, stock, purchasing, partner, and reporting. Re-entering the same information manually limits growth and increases the chance of error.

One connected system
Information moves forward without being manually re-entered.
The system is deliberately modular: each part solves a specific operational problem, while shared flows connect them.

Webshop and accounting
WooCommerce and Minimax share the information required for an invoice.
Customer, product, order, and invoice information moves from the webshop into the accounting flow. Automation removes repeated invoice creation, while validation keeps control over the result.
- Validate required information
- Prepare customer and invoice
- Connect products and line items
- Track synchronization outcomes
Stock and suppliers
Sales become purchasing guidance, and a supplier invoice becomes a stock-entry draft.
Current stock and recent sales indicate what should be reviewed or reordered first. A supplier document can prepare line items for human review before creating a Minimax draft.
- Stock alongside recent sales
- Reorder priorities
- Read supplier-invoice line items
- Review before a stock-entry draft
Partner growth
The affiliate program connects onboarding, attribution, commission, and payout.
A custom program automates partner signup and guidance, links and coupons, repeat-customer attribution, notifications, commission calculation, and payout requests.
- Automated signup and onboarding
- Links, coupons, and repeat customers
- Partner view of orders and commission
- Redemption history and payout requests
Supporting operational layers
Connections continue wherever a decision needs better information.
The same operational approach supports a wider set of processes that do not each need their own product or platform.

Supported outcomes · July 2026
Results stay attached to the real workflow and their calculation basis.
Čajanka is owned by Zmile d.o.o. These outcomes come from its own daily operations, not an external-client relationship.
- 01More than 83 hours
saved on invoicing in 2026 so far
500 orders × approximately 10 minutes of avoided manual invoice creation = about 83.3 hours. - 02About one hour
saved per supplier stock entry
Approximately 60 minutes of manual preparation is avoided because the supplier invoice produces a review-ready draft; human review remains. - 03Approximately 10%
of monthly sales attributed to affiliates
Revenue from affiliate-attributed orders ÷ total monthly sales revenue ≈ 10%. Private commercial totals are not published.
