Professional-firm platform launch story

Cases, clients, billing.the whole firm in one.

PraxisFlow centrally manages professional-firm operations as a multi-tenant SaaS. It unifies case & task management, client engagement (LINE/email), billing & payments, document templates and an office-site CMS on a single platform.

These challenges unique to professional firms — scattered cases, inconsistent client contact and billing overhead — were built in-house from scratch in 16 months: a new-SaaS launch story.

CLIENT
About the client

The client powering DX for professional firms.

Our client launched a SaaS business that fully digitizes operations for professional firms handling administrative procedures. The goal: consolidate firm operations — where cases, clients, billing and lead generation had been scattered — onto a single platform.

The key to success was "Unified case management × integrated client engagement × built-in billing and lead generation". A multi-tenant setup usable per firm was needed, so professionals could focus on their core work.

CHALLENGE
Design challenges to solve

Four design challenges to unify firm operations.

More than functional requirements, these were operational efficiency, response quality, cash flow and new-client acquisition — design challenges tied directly to running the firm.

How to unify case management
Remove the Excel/paper sprawl and oversights drop.
How to integrate client communication
Put LINE/email on a single screen, and missed responses are prevented.
How to lighten billing work
Automate billing and payments and month-end load goes down.
How to systematize lead generation
Build in an office website and new-client acquisition grows.
