Why teams connect Notion and Plex ERP

Bridge the tools people work in and the system the business runs on: real-time, two-way sync between Notion and Plex ERP.

The ERP holds the records the business is run on, and it is rarely where day-to-day work happens. Notion is closer to the work, and the two often need the same facts about the same people, organizations, and transactions. Bridging them by hand, or by nightly file transfer, leaves each side out of date for hours at a time.

Stacksync syncs Comments, Files and attachments, Pages, Databases / Data sources in Notion with Parts, Inventory, Production jobs, Sales orders in Plex ERP bi-directionally and in real time, with field-level mapping and rules for which system wins on conflict. Changes made where the work happens reach the system of record within seconds, and the reverse.

Common use cases

  • 01 Read Notion wiki Pages and their Blocks into a database or search index for internal knowledge retrieval.
  • 02 Two-way sync a Notion projects or tasks data source with a Postgres table so engineers work in SQL while the team edits Pages in Notion, mapping status, date, and assignee properties both ways.
  • 03 Mirror purchase orders and receipts to accounting or planning tools.
  • 04 Feed quality and scrap data to dashboards supervisors check without logging into Plex.

Common sync patterns

Where Notion faces customers and Plex ERP carries account records

Order, invoice, or account status from Plex ERP appears alongside the customer in Notion, so front-line teams answer from live data.

Where Plex ERP is the HR or people system of record

Worker and organization data from Plex ERP stays current in Notion, so the tools people use daily reflect the org as it actually is.

Master data corrections travel

A customer, supplier, or contact detail corrected in either system updates the other, ending duplicate maintenance.

What you can sync between Notion and Plex ERP

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.

Notion objects Plex ERP objects How this pairing syncs
Comments Page and inline discussion threads; can be read and created, useful for surfacing Notion activity in another system. Production jobs Shop-floor work records combining ERP and MES data for output reporting Comments is specific to Notion and Production jobs to Plex ERP — each maps to any object or custom field on the other side.
Files and attachments File-property and file-block values. Notion-hosted URLs are temporary and expire, so files are re-fetched or copied at sync time. Sales orders Demand records written in from e-commerce or EDI channels and read out for fulfillment status Files and attachments is specific to Notion and Sales orders to Plex ERP — each maps to any object or custom field on the other side.
Pages The core content unit and also every row of a database; synced two-way as records, with typed properties mapping to table columns. Purchase orders Procurement records mirrored to accounting and planning systems Pages is specific to Notion and Purchase orders to Plex ERP — each maps to any object or custom field on the other side.
Databases / Data sources Collections of pages with a typed property schema. Since the 2025-09-03 API a database is a container holding one or more data sources; syncs target a specific data_source_id. Customers Account records kept consistent with the sales team's CRM Databases / Data sources is specific to Notion and Customers to Plex ERP — each maps to any object or custom field on the other side.
Properties Typed columns on a page — title, rich_text, number, select, multi_select, date, people, relation, status, checkbox, URL. Read and written both ways. Suppliers Vendor records aligned with procurement and AP tools Properties is specific to Notion and Suppliers to Plex ERP — each maps to any object or custom field on the other side.
Blocks The page body — paragraphs, headings, to-dos, tables — nested as children and fetched recursively, separate from a page's properties. Shipments Outbound logistics records synced to trading partners and tracking systems Blocks is specific to Notion and Shipments to Plex ERP — each maps to any object or custom field on the other side.

How changes propagate between Notion and Plex ERP

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

Notion Plex ERP Sub-second propagation

DetectionNotion notifies Stacksync of record changes through webhook events. Workspace webhooks (page.created, page.content_updated, data_source.schema_updated, comment.created.

DeliveryEach detected change is written to Plex ERP through its API, with automatic retries and rate-limit backoff.

Plex ERP Notion Interval-based propagation

DetectionStacksync polls Plex ERP for changes on an incremental schedule, reading only records changed since the previous pass. Polling.

DeliveryEach detected change is written to Notion through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Notion: Average of ~3 requests/second per integration with some bursts; 429 with a Retry-After header when exceeded. Payloads capped at 500 KB and 1000 block elements.
  • Plex ERP: Subject to the platform's API rate limits.
