Introduction
Banking‑as‑a‑Service (BaaS) empowers payment companies to embed regulated banking, card issuance, and digital banking services via third-party platforms. A rigorous BaaS vendor selection process is essential for securing operational reliability, regulatory compliance, and sustainable profitability, especially in a market projected to grow rapidly over the coming decade. In this case study we’ll explain how Allyiz helped a large payment services provider solve the complexity and financial risk of selecting the right banking-as-a-service vendor.
The Challenge: Finding the Right Banking‑as‑a‑Service Vendor
The client was a large payment services provider who intended to launch card issuing and digital banking offerings. Since internal infrastructure or licenses were absent, they needed expert Banking‑as‑a‑Service consulting to navigate vendor options, assess capability fit, and forecast financial performance over three years.
Client Background
The client came to Allyiz with no hold on core banking or issuing licenses. They needed a BaaS provider to help embed digital banking capabilities quickly, ensure regulatory coverage, and support card programs through APIs - all while maintaining tight cost discipline and operational flexibility.
Allyiz’s Approach to Selecting BaaS Vendor
Allyiz structured the vendor evaluation through a detailed implementation methodology:
Requirement gathering and prioritization to align on technical and functional must-haves.
Organizing vendor demos to assess onboarding workflows, risk controls, card lifecycle, and APIs.
Developing two evaluation models:
A functionality model with different weighted criteria.
A pricing and financial model, projecting 3‑year revenues, costs, and net profit.
Securing clarifying responses from vendors to eliminate ambiguities in proposals.
Assessing four vendors across onboarding, card and banking solutions, operations, and overall fit.
Comparing Vendors: BaaS Cost and Functionality Comparison
The outcomes of the evaluation models were revealing:
Vendor #1 achieved the highest functional score (88%), thanks to its hybrid licensed bank plus BaaS offering, but sacrifice revenue share limited profitability.
Vendor #2 was a pure BaaS platform, required integrations for banking and card operations, but delivered the highest net profit.
Vendor #3 demonstrated strong functionality but imposed a steep setup fee.
Vendor #4 lagged in flexibility under its partnership model and produced a negative net profit.
This side-by-side cost and functionality comparison allowed the client to weigh trade-offs between upfront costs, operational completeness, and long-term profitability.
Key Results: BaaS Profitability Analysis and Strategic Insights
Through Allyiz’s structured scoring and modeling, the client gained deep clarity on strategic trade-offs:
Vendor #1 emerged as the most functional, but capped financially due to interchange splits.
Vendor #2 delivered superior profit potential but demanded external integrations.
Vendor #3 offered powerful tech, but high initial investment undermined ROI.
Vendor #4 proved operationally restrictive and financially unfeasible.
With transparent functional and financial data, Allyiz client could make a confident, strategically-aligned vendor choice.
FAQ
What should be prioritize in a BaaS vendor selection?
The company should focus on functionality fit (e.g. onboarding, card issuance, risk infrastructure), integration flexibility, pricing structure (setup fees vs interchange revenue share), and long-term profitability through transparent financial modeling.
Why combine functional and financial evaluation?
Qualitative capability alignment ensures the vendor can meet technical needs; quantitative financial modeling clarifies ROI and strategic viability. Both are critical.
Why is digital banking technology consulting important now?
As demand for API-based services and embedded finance explodes and regulatory expectations rise, expert guidance ensures correct vendor alignment, risk controls, and scalable tech strategy.
