Whether you use the dashboard or the API, this page explains how Retrac structures your data.

​
Overview

Everything belongs to a workspace. Within a workspace you define items (your product catalog), locations (where stock lives), and tags (optional organization). Inventory balances store the current on-hand quantity for each item at each location. Every change to stock creates an inventory movement — an append-only audit record.

​
Workspaces

A workspace is your company’s inventory environment: one catalog, one team, one billing plan, and one set of usage limits.
  • Each person can belong to multiple workspaces (e.g. separate businesses or departments).
  • The workspace slug appears in your dashboard URL: app.retrac.co/{slug}/inventory.
  • Find the workspace ID under Settings → General when using the API.

​
Locations

Locations represent physical or logical places where stock is held:
  • Warehouse — main storage
  • Van / Truck — mobile stock
  • Site — job site or retail floor
  • Other — anything else
Each workspace has a default location (created automatically as “Inventory”). New items can receive opening stock at the location you have selected on the inventory page.

​
Inventory balances

The balance for an item at a location is the on-hand quantity right now. Balances change when you:
  • Set opening stock or adjust stock
  • Complete a transfer (out from source, in at destination)
  • Revert a transfer (owner only)
Balances are always derived from the movement ledger — you cannot edit history, only add new movements.

​
Transfers

A transfer moves quantity from one location to another. In Retrac, transfers are instant: when you create a transfer, stock moves immediately and the transfer is marked completed.
  • A transfer has one source and one destination location.
  • It can include multiple line items, each with its own quantity.
  • Workspace owners can revert a completed transfer, which restores stock and writes reversal movements.

​
Movements (audit ledger)

Every stock change creates a movement record. Movement types include: View movements under Inventory → Movements. They are read-only.

Tags

Tags are workspace-scoped labels with a name and color. Assign one or more tags to an item to filter the inventory list.

Usage limits

Plans enforce limits on:
  • Total items — cumulative count; does not reset monthly
  • Transfers — counted per billing cycle
  • Locations, tags, and users — workspace caps
See Billing & plans for current limits per plan.
