Project Foundation

Problem Statement, Baseline, And Success Criteria

Clear pre-project constraints and measurable targets establish how outcomes are evaluated.

Problem Statement

Each system exported CSV on a different clock, so finance never matched operations.

Business Overview

What The Engagement Needed To Deliver

Infinoid implemented an API layer between billing, CRM, and fulfilment so events had a single owner, retries, and an audit trail.

Challenges And Solutions

How The Product Direction Was Resolved

Key Challenges

Vendor Islands

Each system exported CSV on a different clock, so finance never matched operations.

Silent Failures

Webhook timeouts vanished without a retry queue or alert.

No Contract

Field names drifted whenever a vendor shipped an update.

Implemented Solutions

Mapped a versioned payload contract for the systems that had to stay.

Put retries and dead-letter handling in front of vendor APIs.

Exposed an operations log the client team could search without engineering.

Key Decisions And Tradeoffs

Why This Approach Was Chosen

Mapped A Versioned Payload Contract For The Systems That Had To Stay.
