Why teams connect AWS S3 and Microsoft Dynamics 365 Sales

Sync Microsoft Dynamics 365 Sales into AWS S3 continuously and push warehouse results back onto CRM records, one two-way connection instead of two pipelines.

The CRM feeds the warehouse and the warehouse should feed the CRM: relationship data flows one way, and computed scores, segments, and customer context flow back. Most teams build the first half as a batch pipeline and never quite get to the second.

Stacksync does both with one connection. Orders, Invoices, Activities, Custom Tables from Microsoft Dynamics 365 Sales land in AWS S3 as live tables, updated within seconds, and columns computed in AWS S3 write back to fields in Microsoft Dynamics 365 Sales. There is no separate ETL and reverse-ETL stack to stitch together and no jobs to babysit.

Common use cases

  • Write product usage and warehouse-computed scores onto Dataverse tables so sellers see them in the model-driven app.
  • Run a two-way dual-run between Dynamics and another CRM during a migration.
  • Stage bulk loads for warehouses that ingest from object storage.
  • Archive change history from ongoing syncs as timestamped files for audit and replay.

Cleanup that sticks

Deduplication and normalization done in AWS S3 can be written back, so warehouse-side cleanup actually fixes the CRM.

CRM analytics on live data

Accounts, contacts, and activity from Microsoft Dynamics 365 Sales are queryable in AWS S3 moments after they change, so dashboards stop lagging the reality they describe.

Scores and segments back on the record

Lead scores, churn risk, or usage segments computed in AWS S3 appear as fields in Microsoft Dynamics 365 Sales, where the people working accounts actually see them.

What you can sync between AWS S3 and Microsoft Dynamics 365 Sales

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.

AWS S3 objects Microsoft Dynamics 365 Sales objects
Event Notifications Notifications on object creation or deletion that trigger incremental processing. Accounts Company records in Dataverse; the usual anchor for two-way sync with databases and ERPs.
Access Points Scoped network endpoints used to grant a sync narrow access to a bucket. Contacts Person records linked to accounts; synced with marketing and support systems.
Multipart Uploads The mechanism used to write large export files reliably. Leads Prospect records; written in from enrichment or web forms, read out on qualification.
Buckets Top-level containers a sync targets; region and policy are set at this level. Opportunities Deal records with stages and estimated revenue; synced for pipeline reporting and close-triggered workflows.
Objects The stored files (CSV, JSON, Parquet); syncs read them as datasets or write exports into them. Quotes Pricing proposals; often synced with CPQ or ERP pricing data.
Prefixes Key-name paths used to partition synced datasets, since S3 has no real directories. Orders Confirmed sales; handed off to ERP systems for fulfillment and billing.
