Why teams connect DEAR Inventory and Notion
Bridge the tools people work in and the system the business runs on: real-time, two-way sync between Notion and DEAR Inventory.
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 Bridging them by hand, or by nightly file transfer, leaves each side out of date for hours at a time.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 Pages, Databases / Data sources, Properties, Blocks in Notion with Stock adjustments and transfers, Assemblies / Production, Locations, Products in DEAR Inventory 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 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.
- 02 Push rows from a warehouse or another database into a Notion data source as Pages so ops and leadership read live metrics in a familiar Notion view.
- 03 Sync stock levels and product data to e-commerce storefronts and a CRM so sales quotes reflect real availability.
- 04 Push sale orders from a storefront or CRM into DEAR for fulfillment without manual re-entry.
Common sync patterns
Where Notion faces customers and DEAR Inventory carries account records
Order, invoice, or account status from DEAR Inventory appears alongside the customer in Notion, so front-line teams answer from live data.
Where DEAR Inventory is the HR or people system of record
Worker and organization data from DEAR Inventory 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 DEAR Inventory and Notion
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.
| DEAR Inventory objects | Notion objects | How this pairing syncs | |
|---|---|---|---|
| Stock adjustments and transfers Inventory movement transactions that explain changes in availability. | Properties Typed columns on a page — title, rich_text, number, select, multi_select, date, people, relation, status, checkbox, URL. Read and written both ways. | Stock adjustments and transfers is specific to DEAR Inventory and Properties to Notion — each maps to any object or custom field on the other side. | |
| Assemblies / Production Bill-of-material and production records for light manufacturing workflows. | Blocks The page body — paragraphs, headings, to-dos, tables — nested as children and fetched recursively, separate from a page's properties. | Assemblies / Production is specific to DEAR Inventory and Blocks to Notion — each maps to any object or custom field on the other side. | |
| Locations Warehouses and bins that scope stock levels and fulfillment. | Formula and Rollup properties Values computed by Notion from other fields; read-only, so they are pulled out for reporting but never written back. | Locations is specific to DEAR Inventory and Formula and Rollup properties to Notion — each maps to any object or custom field on the other side. | |
| Products SKU records with pricing, suppliers, and bill-of-material links; the master data most syncs start from. | Users Workspace members and bots referenced by people properties; read-only — users cannot be created or invited through the API. | Products is specific to DEAR Inventory and Users to Notion — each maps to any object or custom field on the other side. | |
| Stock levels Per-location availability derived from inventory transactions; read-heavy in storefront syncs. | Comments Page and inline discussion threads; can be read and created, useful for surfacing Notion activity in another system. | Stock levels is specific to DEAR Inventory and Comments to Notion — each maps to any object or custom field on the other side. | |
| Sale orders Customer orders through their pick/pack/ship lifecycle; synced with storefronts and CRMs. | 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. | Sale orders is specific to DEAR Inventory and Files and attachments to Notion — each maps to any object or custom field on the other side. |
