Challenge

Sole traders and small businesses often invoice using software that is either expensive or overcomplicated — or they simply use a spreadsheet. Bizko's goal was a local, straightforward and affordable tool that covers the everyday paperwork of a small business.

This was not a brochure website but the development of a full web application: customer records, documents and numbering sequences have to be flawless, because these are accounting records.

Goal: A Slovenian, straightforward and affordable web tool for invoices, quotes and travel orders that covers a small business's everyday paperwork and makes handover to the accountant easy.

Solution

We built a custom web application: issued and received invoices, quotes and proforma invoices, a record of payments and travel orders — all in a simple interface that requires no accounting knowledge.

We paid particular attention to handing documents over to the accountant: structured exports instead of emailing individual PDFs one by one. New users are welcomed with a free trial — no card and no commitment.

What the application does

  • Issued and received invoices

    Issuing, record-keeping and an overview of payments in one place.

  • Quotes and proforma invoices

    From a quote to an invoice in a few clicks.

  • Travel orders

    Managing travel orders with mileage for sole traders and companies.

  • Handover to the accountant

    A structured handover of documents — no more emailing PDFs one by one.

  • Free trial

    Registration and a trial with no payment card.

  • Marketing site with pricing

    Features, pricing and news — all leading to the trial.

Result

Bizko is a live, working service today, with public pricing and a free trial — from an idea to a product that simplifies everyday paperwork for small businesses. The project shows that alongside brochure websites we also develop full web applications.
