Empowering a Fintech SaaS Platform with SAP Integration to Accelerate Enterprise Growth

The Client

A rapidly growing Fintech SaaS provider based in North America, offering automated financial workflows including Accounts Payable (AP) automation, billing, and digital payments.

The platform served mid-market clients successfully but struggled to meet the integration expectations of enterprise prospects running SAP S/4HANA or SAP ECC.

The Business Challenge

As the SaaS company expanded into enterprise segments, a critical gap emerged the lack of native SAP integration.

This limitation directly impacted deal conversions and operational efficiency.

Key business challenges included:

• Losing enterprise deals because procurement and finance teams required direct SAP integration for data posting and reconciliation.
• Manual efforts to reconcile invoices, payments, and journal entries between the SaaS platform and SAP FI/CO modules.
• Extended onboarding time for new customers due to one-off integration work for each SAP environment.

The Technical Challenge

The client’s engineering team faced significant hurdles integrating with SAP systems securely and reliably.

Primary technical challenges:

• Requirement for secure, bidirectional connectivity using SAP-approved protocols (BAPI, IDoc, or API).
• Need for real-time synchronization of financial transactions, vendor records, and payment status updates.
• Handling SAP-specific data models such as Vendor Master, GL Accounts, and Company Codes.
• Ensuring scalability to support multiple SAP versions (ECC and S/4HANA).

Integration Solution

Satva Solutions architected a reusable SAP integration connector tailored for the client’s SaaS platform enabling enterprise-grade data exchange with SAP FI/CO and related modules.

Key Components Implemented

1. Reusable SAP Connector Module

   Developed using SAP Cloud Platform Integration (CPI) and REST APIs, supporting both inbound and outbound data exchange with SAP ECC and S/4HANA.

2. Financial Transaction Automation

   • Automated posting of invoices, payments, and journal entries into SAP FI/CO using BAPI and IDoc interfaces.
   • Enabled vendor synchronization and real-time payment status updates between systems.

3. Enterprise Scalability & Security

   • Supported multi-tenant configuration to allow each enterprise client to connect with their unique SAP instance.
   • Implemented OAuth-based authentication and encryption for secure data transmission.

4. SAP Data Mapping Layer

   • Created standardized data transformation templates for GL Accounts, Vendor Master, and Cost Centers, ensuring accurate posting and compliance with SAP data structures.

Business Impact & KPIs

Following the deployment of Satva’s integration framework, the Fintech SaaS platform achieved measurable improvements in growth, customer acquisition, and operational efficiency.

Key Outcomes:
