Why teams connect Firebase and SAP

Give your engineers SAP's data in Firebase: read it with normal queries, write back through the sync, and skip the ERP API entirely.

ERP data sits behind interfaces built for the ERP's own modules, not for your internal systems. Teams that need those records, for reporting services, internal tools, or automations, end up writing integration code against a strict API and maintaining it through every upgrade.

Stacksync mirrors GL Accounts and Journal Entries, Production Orders, Inventory / Stock, Cost Centers from SAP into Firebase and keeps both sides consistent in real time. Whatever SAP is the system of record for, whether financials, operations, people, or procurement, those records become rows your code can query, and changes written in Firebase sync back into SAP with its validations respected.

Common use cases

  • Write CRM-side changes (plan, status, owner) back into Firestore documents the app reads.
  • Combine Firebase Authentication users with billing and CRM records into one customer table.
  • Publish plant-level inventory to e-commerce and planning systems on change or on schedule.
  • Replicate journal entries and billing documents to a warehouse for finance analytics without loading the ERP.

Where SAP is the HR system of record: people data for internal systems

Worker and org records stay current in Firebase for provisioning, access, and reporting systems that read from the database.

Controlled write-back

Choose exactly which tables and fields may flow from Firebase back into SAP, keeping the ERP authoritative.

Read ERP records with a query

Records from SAP live in Firebase as ordinary tables or collections, joinable with the rest of your data.

What you can sync between Firebase and SAP

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.

Firebase objects SAP objects
Cloud Storage Objects Files referenced from documents; usually synced as metadata plus URLs. Purchase Orders Procurement documents synced with supplier portals and spend tools.
Cloud Functions Triggers Server-side hooks that fire on document changes and can push updates outward. Outbound Deliveries Shipment documents synced to WMS, carriers, and customer portals.
Firestore Collections Top-level groupings of documents that a sync maps to tables or SaaS objects. Billing Documents Invoices read for AR status and replicated for revenue reporting.
Firestore Documents Schemaless JSON-like records, the primary unit synced to and from external systems. GL Accounts and Journal Entries Financial postings replicated to warehouses for group finance analytics.
Subcollections Nested collections under documents, typically flattened into related tables during sync. Production Orders Manufacturing orders exchanged with MES and scheduling systems.
Realtime Database Nodes JSON tree paths in the older Realtime Database, synced by path. Inventory / Stock Plant and storage-location quantities synced to storefronts and planning tools.
What ships with Firebase ⇄ SAP

Connect Firebase and SAP for flexible, real-time data sync.

Real-time sync, workflow automation, event queues, EDI, and monitoring, for every Firebase–SAP connection.

Real-time

Two-way sync

Changes in Firebase or SAP instantly reflect in both systems. No stale data, no manual imports.

No-code + pro-code

Workflow automation

Trigger automated workflows whenever Firebase or SAP data changes, update records, fire webhooks, or kick off sequences without brittle API scripts.

At scale

Event queues

Handle millions of events per minute without losing a single Firebase or SAP record.

Observability

Monitoring

Track your Firebase ⇄ SAP sync health, view errors, and replay failed events in one click.

Trading partners

EDI

Transform legacy EDI complexity into simple database interactions between Firebase and SAP.

How the Firebase and SAP connectors work

Firebase

Integration surface
REST and gRPC APIs, typically accessed through the Firebase Admin SDK
Authentication
Google service account credentials (IAM) for server-side access; Firebase Auth tokens for client contexts
Change detection
Real-time snapshot listeners on Firestore queries and Cloud Functions triggers on document changes
Capabilities
read · write
Rate limits
Subject to Firestore's documented operation quotas and per-document write throughput limits

SAP

Integration surface
OData (v2/v4) APIs on S/4HANA; BAPI/RFC and IDoc on ECC and on-prem systems; SOAP services
Authentication
OAuth 2.0 or basic auth via communication arrangements on cloud editions; SAP user credentials for RFC on-prem
Change detection
Business events via SAP Event Mesh on S/4HANA; change pointers with IDocs or timestamp polling on ECC
Capabilities
read · write · webhooks
Rate limits
Throttling is configured at the gateway and tenant level rather than as a single published rate limit
How it works

How to connect Firebase to SAP — three steps, no code

Configure and sync within minutes, no code. Whether you sync 50k or 100M+ records, Stacksync handles the queues, infra, and plumbing. Integrations are non-invasive and need zero setup on your systems.

  1. 01

    Connect your apps

    Authenticate Firebase and SAP with each platform's native method — OAuth, API keys, or service accounts — plus secure options like SSH tunneling, IP whitelisting, and VPC peering.
