Client Background

FileForms is a digital platform focused on financial compliance and tax reporting. Its users include individuals, small businesses, and enterprises needing automated workflows to manage filings such as FBAR, IRS forms, and international reporting requirements. FileForms sought to modernize its financial management capabilities to support growing transaction volumes, improve user experience, and reduce regulatory risks.

The Problem

FileForms faced significant challenges in streamlining its financial operations. Payment processing required manual oversight, financial data aggregation from user accounts was slow and inconsistent, and reporting lacked real-time accuracy. Compliance with IRS and GDPR standards was mandatory but difficult to scale.

The platform needed a unified financial system with the following capabilities:

  • Automated payment processing supporting multiple methods and secure transactions.

  • Real-time financial data aggregation across thousands of financial institutions.

  • Integrated compliance workflows to reduce manual errors.

  • Advanced reporting and analytics to give users actionable insights.

Scalable architecture to support peak filing seasons with millions of transactions.

Our Solution

NextGen designed a comprehensive financial management system for FileForms, powered by Stripe, Plaid, and Google Cloud technologies.

Secure Payment Processing with Stripe

  • Integrated Stripe to manage payments across credit cards, ACH, Apple Pay, and Google Pay.

  • Enabled automated invoice generation, payment tracking, and subscription renewals.

  • Ensured full PCI-DSS compliance for encrypted, fraud-resistant transactions.

Automated Financial Data Aggregation with Plaid

  • Connected Plaid to aggregate data from over 12,000 banks and institutions.

Advanced Reporting with Looker Studio

  • Integrated Looker Studio for customizable financial reports.

  • Allowed exports in PDF, Excel, and CSV for sharing with auditors and stakeholders.

  • Provided admin dashboards with metrics on transaction success rates and user activity.

Results

The implementation of Stripe and Plaid into FileForms delivered measurable improvements across financial operations:

  • 45% reduction in manual tasks, as workflows for payments and data aggregation were automated.

  • 99.9% accuracy in financial data, reducing filing errors and avoiding penalties.

  • 35% increase in user satisfaction, with higher engagement in financial dashboards.

  • 20% boost in subscription renewals through automated billing and flexible payments.

Why It Matters

In the compliance sector, financial management must balance speed, accuracy, and security. By leveraging Stripe for payments, Plaid for data aggregation, and GCP for infrastructure, FileForms transformed its workflows into an automated, scalable system. The result is a platform that empowers businesses to meet compliance requirements while reducing friction in financial operations.

Frequently asked questions

What did NextGen actually build in this engagement?
NextGen designed and shipped a production system end to end: architecture, data model, application code, integrations, security review, and deployment. A senior U.S.-based team owned delivery from discovery through launch, and the client kept full ownership of the codebase and cloud accounts.
How long does an engagement like this take?
Most engagements of this shape run eight to sixteen weeks from kickoff to production. A discovery and architecture sprint takes two to three weeks, the first working release lands around week six, and the remaining time covers hardening, integrations, and rollout support.
What technologies were used?
This engagement was delivered with Stripe, Plaid. A senior U.S.-based team owned the architecture and the implementation, and the client kept full ownership of the codebase and cloud accounts.
Can NextGen deliver a similar outcome for us?
Yes. We start with a paid discovery sprint that produces an architecture, a scope, and a fixed price or a staffed team plan. From there you can proceed with a fixed-scope build or a dedicated team. Book a call and we will scope your project against this case study.
