01 / PRODUCT

One clear flow you can verify yourself.

Problem

Not a static mockup

A finished document without registration or server-side transfer of business details.

Approach

Input → logic → result

The user works with their own inputs and receives a useful result directly in the interface.

Verification

Public version

The product is available through a direct link and the main flow can be tested without requesting access.

02 / WORKING FEATURES

Product behaviour, not a technology list.

Three document types

Invoice, estimate and commercial proposal share one editor.

Dynamic line items

Products and services can be added and removed without reloads.

Automatic totals

Subtotal, tax and final amount update immediately.

RUB / USD / EUR

The document supports three currencies.

Local draft

Data is stored only in the current browser's localStorage.

Print / PDF

Print CSS creates a clean document layout.

03 / TRY IT

Open the product and run the main flow.
