I'm looking for a professional to create a bidirectional integration between an ERP system and HubSpot CRM.
Must have:
Proven ERP API integration experience (provide specific examples with systems like NetSuite, SAP, Dynamics, or similar)
SQL Server experience for reading ERP data
HubSpot API v3 experience
Scope of work:
Bidirectional sync: customer master, primary contact, credit status, and
ERP to HubSpot: sales orders, invoices, and products (via SQL reads)
HubSpot to ERP: new accounts, contacts, and sales orders (via API)
Technical challenges to address:
ERP system allows only one contact per customer while HubSpot supports multiple contacts per company
Bidirectional customer credit hold status sync
Proper use of ERP APIs vs direct SQL writes for data integrity
May require future enhancements after initial implementation.
Technical test questions (answer in proposal):
How do you handle syncing when one system allows only one contact per company while the other supports multiple contacts?
What's your approach for syncing status flags (like credit holds) bidirectionally between systems?
When integrating with an ERP system, when do you use the ERP's API vs direct SQL writes, and why?
Please provide:
Your hourly rate (within $20-40/hr range)
Estimated hours for this scope
Specific ERP integration project examples
Your technical approach (middleware platform, hosting, architecture)
