The challenge

What needed solving.

Small teams outgrow spreadsheets but find accounting suites too heavy. The concept focuses on the few workflows that matter, with an architecture ready for more customers and features.

Our approach

How we would deliver it.

01

Discovery and scope

A focused first release covering invoices, reminders and client portals, with a clear roadmap for later.

02

Multi-tenant foundation

Workspace isolation, role-based permissions and an audit log from the first commit.

03

Subscription billing

Plans, trials and upgrades through a hosted billing provider with webhook-driven account states.

Highlights
  • Workspace-based multi-tenancy
  • Role and permission system
  • Subscription billing integration
  • Monitoring and error tracking
What this concept demonstrates

“A pragmatic SaaS architecture that ships a useful product early without painting the codebase into a corner.”

Concept project for illustration. No client, results or metrics are implied.
