Integrated Billing System SaaS
A multi-tenant SaaS platform to automate the entire billing lifecycle, from invoicing and subscriptions to payment processing and revenue recognition.
Understanding Financial Workflows
Conducted interviews with 40+ small business owners, accountants, and finance managers to map out the entire billing process, from customer acquisition to revenue reporting.
Research Interview Outcome
The qualitative interviews with 40 participants revealed that billing errors were the most significant pain point, followed closely by the complexities of managing subscriptions.
Defining the Core Problem
Businesses are bogged down by inefficient, manual billing processes that stifle growth, strain resources, and create poor customer experiences.
Problem Statement
The absence of an automated, integrated billing system forces businesses to rely on a patchwork of spreadsheets and manual tools. This leads to revenue leakage from billing errors, wasted hours on administrative tasks, and a lack of real-time financial data needed for strategic decision-making.
User Personas
The Small Business Owner
"I need to get paid on time without spending half my week chasing invoices. I need a simple system that just works."
The Finance Manager
"I need accurate revenue reports and a clear audit trail. Our current process is a reconciliation nightmare."
The Accountant
"I need the system to handle complex tax calculations and integrate with our accounting software seamlessly."
The End Customer
"I want to easily view my past invoices, update my credit card, and understand my subscription."
Key Pain Points
Manual Invoicing & Human Error
Businesses spend countless hours creating and sending invoices manually, leading to mistakes, and delayed payments.
Complex Subscription Management
Managing different subscription tiers, prorations, and upgrades/downgrades manually is a significant operational headache.
Payment Reconciliation Challenges
Matching incoming payments with outstanding invoices is a time-consuming and error-prone process for finance teams.
Lack of Financial Insights
Without a centralized system, it's difficult to get a clear view of key metrics like Monthly Recurring Revenue (MRR) and customer churn.
Billing Lifecycle Architecture
The system architecture was designed around the end-to-end billing lifecycle, from product and plan creation to automated invoicing, dunning management for failed payments, and finally, revenue analytics.

Designing an Automated System
The core idea was a modular SaaS platform that businesses could configure to their specific needs, with a powerful admin dashboard and a self-service portal for their customers.
Key Design Decisions
Ideation focused on automation, flexibility, and data visibility.
- • **Flexible Product Catalog:** Allow businesses to create diverse products, plans, and add-ons with different billing cycles.
- • **Automated Invoicing Engine:** A core engine to generate and deliver invoices automatically based on subscription schedules.
- • **Customer Self-Service Portal:** A secure portal for end-customers to manage their subscriptions, view payment history, and update billing information.
Building and Validating
High-fidelity prototypes of the admin dashboard and customer portal were created and tested with target users to refine the user experience and validate the workflow.
Prototype Highlights
Prototypes simulated the complete journey: a business owner setting up a new subscription plan, a customer signing up, and the finance manager viewing the revenue dashboard.
Usability Study Results
Round 1 (Business Owners)
- Users need a dashboard with key financial metrics visible at a glance.
- The process of creating a new subscription plan needs to be highly intuitive.
Round 2 (Finance Managers)
- Automated reminders for overdue invoices are a must-have feature.
- Integration with accounting software (like QuickBooks) is a critical requirement.
- The customer portal needs a clear layout for viewing invoices and updating payment methods.
- Bulk import/export of customer and invoice data is necessary.
Impact & Results
Project Impact
The SaaS platform dramatically reduced the time businesses spent on billing by up to 60%. It virtually eliminated manual billing errors and provided clear, real-time financial dashboards, empowering owners to make better strategic decisions.
Key Learnings
Building a billing system requires an obsessive focus on accuracy, security, and flexibility. The design had to be robust enough to handle complex edge cases while remaining simple enough for non-technical users to manage their business finances.
