Why teams connect Close and IBM AS/400

Treat Close like part of your database: its records live in IBM AS/400 as real tables, and writes in either place sync to the other in seconds.

Product and engineering teams constantly need CRM data, and the CRM API is a poor way to get it: rate limits, pagination, custom objects, and integration code that breaks when an admin renames a field. What they actually want is the data in IBM AS/400, where it can be queried and joined like everything else.

Stacksync mirrors Custom Fields, Users, Smart Views, Leads from Close into Rows / records, Journals and journal receivers, Data queues, Libraries in IBM AS/400 with real-time, bi-directional sync. Read CRM records with plain queries; write updates from your application and they appear in Close with validation intact. Go-to-market teams keep working in the CRM, engineers keep working in the database, and neither has to think about the other.

Common use cases

  • Write product usage or firmographic data from an internal database onto Close lead custom fields to prioritize follow-up.
  • Sync Close leads and opportunities into Postgres or a warehouse for pipeline reporting outside Close's built-in reports.
  • Use journal-based change capture to replicate IBM i data into a cloud warehouse for reporting.
  • Keep customer and item files aligned with an ecommerce platform or modern ERP during phased modernization.

Field and stage updates in Close arrive as row changes in IBM AS/400, ready to drive jobs and notifications.

What you can sync between Close and IBM AS/400

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

Close objects IBM AS/400 objects
Custom Fields Org-specific fields on leads, contacts, and opportunities; addressed by stable field ids in syncs. Journals and journal receivers The change log that enables log-based CDC on journaled files.
Users Sales reps referenced as owners on leads, opportunities, and activities. Data queues Program-to-program messaging objects sometimes used to hand events off to integrations.
Smart Views Saved lead searches that can scope which records a segment-based sync pulls. Libraries The schema-equivalent containers that scope which files a sync reads.
Leads The top-level record in Close; represents a company and holds its contacts, opportunities, and activity history. Physical files (tables) The Db2 for i tables mapped directly to sync targets.
Contacts People nested under a lead, with emails and phone numbers used for outreach syncs. Logical files (views) Indexed or filtered views over physical files, usable as read sources.
Opportunities Deal records with value, confidence, and status; commonly synced to reporting and billing systems. Members Sub-partitions of files in legacy applications, flattened or selected during syncs.
