Why teams connect Firebase and Sage 100

Give your engineers Sage 100'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 Inventory Items, Sales Orders, AR Invoices, Purchase Orders from Sage 100 into Firebase and keeps both sides consistent in real time. Whatever Sage 100 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 Sage 100 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.
  • Sync customers, invoices, and payment status into a CRM so sales sees AR standing without opening the ERP.
  • Push e-commerce and EDI orders into the Sales Order module instead of rekeying them.

Controlled write-back

Choose exactly which tables and fields may flow from Firebase back into Sage 100, keeping the ERP authoritative.

Read ERP records with a query

Records from Sage 100 live in Firebase as ordinary tables or collections, joinable with the rest of your data.

Internal tools and automations without API code

Scripts and services read and write the synced tables; Stacksync handles the Sage 100 interface, limits, and retries.

What you can sync between Firebase and Sage 100

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 Sage 100 objects
Firestore Collections Top-level groupings of documents that a sync maps to tables or SaaS objects. Purchase Orders Procurement documents read for spend and receiving workflows.
Firestore Documents Schemaless JSON-like records, the primary unit synced to and from external systems. GL Accounts Chart of accounts read for mapping transactions in finance integrations.
Subcollections Nested collections under documents, typically flattened into related tables during sync. Journal Entries Posted GL activity replicated to warehouses for FP&A.
Realtime Database Nodes JSON tree paths in the older Realtime Database, synced by path. Customers AR customer master records synced to CRMs for account and credit visibility.
Authentication Users User accounts read into CRMs and warehouses for customer records. Vendors AP vendor master records synced with procurement and payment tools.
Cloud Storage Objects Files referenced from documents; usually synced as metadata plus URLs. Inventory Items Item master with pricing and quantities, synced to e-commerce catalogs.
