Build With Your Own Licence or a Licensed Partner?

Case study: what we have built

Real projects delivered by the PerfectionGeeks team, with the problem, what we built and the outcome.

CEOAS: an accounting platform for Indian businesses

PerfectionGeeks designed and built CEOAS from scratch: a cloud accounting platform that gives Indian SMBs GST-ready invoicing, two-way Tally sync, role-based team access and live financial dashboards in one workspace. It is live at app.ceoas.com.

The problem

Businesses kept ledgers in Tally, invoices in spreadsheets, team coordination on WhatsApp and GST work on paper. Owners waited for weekly Excel reports.

What we built

  • GST invoice engine with automatic GST, GSTIN validation and PDF export
  • Two-way Tally sync, so invoices are never entered twice
  • Customer, vendor and product catalogue with HSN/SAC codes
  • Team roles (Admin, Accountant, Viewer) with an activity audit log
  • Live dashboard: P&L, GST liability, receivables and cash flow
  • Tiered subscription plans with feature gating

Result

Six modules in one platform, replacing four disconnected tools.

“The Tally sync alone saved our team hours every week, and now our business owner gets a real-time dashboard instead of waiting for Monday reports.”

Fintech App Development FAQs

How much does it cost to develop a fintech app?
A fintech MVP typically costs $20,000–$50,000, a full-featured app $50,000–$150,000, and an enterprise platform $150,000 or more. Integrations, card issuing, compliance depth and security testing drive most of the difference.
How long does it take to build a fintech app?
An MVP takes 3–4 months, a full-featured app 5–8 months and an enterprise platform 9–15 months, released in phases. Partner onboarding and app store financial-services review can add a few weeks, so we plan for them from the start.
Do I need a banking or money transmitter licence?
Not always. Many fintech apps launch on a licensed partner, such as a BaaS provider, sponsor bank, e-money institution or lender, and operate under its licence. Your legal advisers confirm the right model for your product and market; we build the software for it.
Which compliance standards do you follow?
It depends on the market and product: KYC and AML everywhere, PCI DSS for card data, GLBA and state rules in the US, FCA rules and Consumer Duty in the UK, PSD2, GDPR and DORA in the EU, and RBI rules in India. We map them in discovery and build the controls in.
Should I build a native or cross-platform fintech app?
Native Swift and Kotlin give the strongest security tooling and performance, which suits banking and trading apps. Flutter or React Native can cut cost for wallets, budgeting and lending MVPs that need both stores at launch.
What features should a fintech MVP include?
Onboarding with KYC, secure login with biometrics and MFA, one core money journey (pay, lend, save or invest), transaction history, notifications, support, and an admin panel for your operations team.
How do you keep a fintech app secure?
Encryption in transit and at rest, MFA and device binding, app hardening, fraud rules, tamper-evident audit logs, and penetration testing before every major release.
Can you integrate Plaid, Stripe or a BaaS provider?
Yes. We integrate open banking aggregators, payment processors, card issuers, BaaS platforms, KYC vendors and credit bureaus, and design the architecture so you can switch providers later.
Will I own the source code?
Yes. The code, data and IP are yours, and the app runs in your own cloud and app store accounts.
Do you sign an NDA?
Yes, before you share product or partner details.
Can you add AI to a fintech app?
Yes: fraud scoring, credit decisioning support, spending insights, document reading and support chatbots, with explainable outputs and human review where decisions affect customers.
Can you modernise an existing banking or finance app?
Yes. We start with a code, security and UX audit, then rebuild the riskiest parts first while the current app keeps running.
Do you provide support after launch?
Yes, under a monthly plan covering monitoring, security patches, OS updates, regulatory changes and new features, with agreed response times.
