Parra is a Croatian B2B accounting platform built to support everyday financial operations through a clearer and more structured digital experience. This project covered both desktop and mobile product design, with a focus on document issuing, invoice management, accounting reports, banking data, and payment tracking. The goal was to make a complex back-office system feel easier to use, easier to scan, and more reliable in day-to-day work.

A big part of the product revolves around document management, so the issuing overview was designed to help users move through large amounts of data quickly.

Invoices, offers, delivery notes, and other records are organized in a structured table with filters, grouped rows, payment indicators, and status cues that make it easier to understand what has been issued and what still needs attention. The interface keeps the information dense, but the hierarchy remains calm and easy to scan.

Creating a document was treated as a guided workflow rather than one long accounting form. Customer information, invoice settings, line items, taxes, and additional details are separated into clear blocks, which reduces friction during entry and helps users stay focused on accuracy.

This part of the product had to support complexity without feeling intimidating, so the layout balances a lot of fields with consistent spacing, sectioning, and clear actions.

Document handling continues after creation, so the status and related-actions view was designed to support the full lifecycle of a record. Users can send, download, share, duplicate, or cancel a document, while also transforming it into connected outputs such as offers, delivery notes, work orders, or pre-invoices.

The linked documents table adds important context by showing how records connect to one another, which is especially useful in accounting systems where one document often leads to the next.

Reporting screens required a different kind of clarity because they deal with layered financial structures rather than simple lists. The balance report organizes classes, groups, and accounts through expandable sections and nested tables that make the hierarchy much easier to follow.

Instead of flattening the data, the design keeps its accounting depth visible while improving readability and navigation for users who need to inspect detailed financial records.

Bank statement management combines several workflows into a single view, including transaction browsing, related documents, account summaries, and multi-currency account information.

The main transaction area stays central, while the right-side panel provides broader financial context without overwhelming the primary task. This creates a workspace where users can review activity, connect it to documents, and keep track of account health at the same time.

On mobile, the experience shifts from wide tables into card-based layouts that surface only the most important information first.

Payment and invoice records are easier to review through due dates, paid status, and total amounts, while filtering remains powerful enough for real use instead of being reduced to a basic search.

The result is a mobile experience that supports quick checks and lightweight management while staying consistent with the desktop product.

Parra was shaped into a clearer and more usable accounting platform across desktop and mobile. They received €3M funding from SQ Capital in 2025 after our collaboration on the MVP and core features.

The design improves how users issue documents, manage financial records, review reports, and track banking activity, while making a complex B2B product feel more structured and more approachable in everyday work.
