This software-as-a-service (SaaS) offers data syncing of events, contacts, and email between Microsoft Exchange and SmartOffice (a finance-oriented CRM). I personally developed every part of this system.
Pertinent features:
- Extensive Microsoft Exchange integration using PHP
- SmartOffice API integration
- Intuit e-commerce integration
- Administrative modules to manage system
- Multiple automated processes to distribute the heavy memory load of many accounts
