About the Client

The client is a multinational B2B SaaS and enterprise technology vendor. It manages over 3,500 active corporate contracts and runs complex multi-tiered subscription architectures globally across five operational legal entities.

The Challenge

A disconnected data architecture was severely restricting the client’s financial agility. While their global sales team was actively winning multi-million-dollar deals on their legacy front-end CRM, their corporate accounting system existed in complete isolation. This was creating business friction.

They approached Aegis Softtech to connect the frontend pipeline data with the backend financial operations, ensuring complete data integrity and instant invoicing:

  • Extensive Invoicing Delays: The client’s financial teams had to wait for the end of the month to manually download and verify large batches of contract CSV files before drafting invoices.
  • High Manual Reconciliation Overhead: Their corporate accountants were spending more than 20 hours a week cross-referencing account structures, dynamic service agreements, and currency translations between the CRM records and ledger lines.
  • Costly Transaction Discrepancies: Their manual data entry process was infesting their issued invoices with errors related to billing addresses, tax codes, and licensing tiers. It was resulting in payment disputes and cash flow disruptions.
  • Delayed Revenue Visibility: Their corporate executives lacked real-time visibility into incoming cash positions. Thus, they relied on retrospective financial closures that lag 15 days behind the active sales pipelines.

The Solution

Our Microsoft Dynamics 365 team built and launched an automated cross-system integration engine that securely links account closures with their corporate financial books.

Secure RESTful API Middleware Integration

We engineered an automated, real-time communication pipeline to eliminate systemic silos:

  • Automated Opportunity Syncing: We used secure middleware layers to build custom API endpoints. It automatically extracts newly closed-won opportunities from the front-end CRM and instantly generates corresponding sales orders in Dynamics 365 Finance.
  • Algorithmic Customer Mapping: We developed data transformation scripts that use global tax IDs to automatically map multi-tiered accounts to their corresponding corporate ledger profiles, preventing duplicate accounts.

Automated Invoicing & Ledger Balancing

We streamlined cash flow tracking and back-office financial compliance:

  • Instant Invoicing Triggers: Our team programmed background event handlers that instantly parse transaction values, automatically issue digital invoices upon deal closing, and apply correct localized tax structures.
  • Intercompany Balancing Automations: Configured native cloud ledger interfaces to automatically allocate proportional multi-entity revenue distributions across the client’s global operating locations instantly.

What Made the Difference?

Full-Lifecycle Engineering Team

We provided the client with a multi-faceted team to manage every aspect, from early cryptographic key architecture down to role-based system training.

Fail-Safe Data Buffering

We designed a persistent asynchronous message buffer to securely queue the client’s financial payloads during peak volume periods. This ensured no transaction is ever lost or dropped.

Rigorous Financial Audit Testing

Executed over 800 synthetic transaction test variations to check the health of complex currency conversions and multi-tier tax computations before live deployment.
