Custom objects
Track the things that make your business different
Event planners track venues, agencies track retainers, studios track equipment. Custom objects give each one its own records and fields, and they work with Flows, the REST API and your AI assistant.
Business includes 5 custom objects, and Solo, Team and Business can add more with the custom objects add-on.

- Record page
- Linked records
- Activity timeline
The problem
Sound familiar?
- We track venues in a spreadsheet because the CRM has nowhere to put them.
- Our retainers don't fit the deal or project fields we're given.
- Every workaround ends with a field called 'Notes 2'.
How it works
From idea to working object
1
Define the object
Name it and add fields from 26 field types, from text and currency to lookups and formulas.
2
Add records
Create records by hand, through the API or with your AI assistant, and discuss them in comments.
3
Link it
Lookup fields connect your object to accounts, projects or any other record.
4
Automate it
Use custom objects in Flows, and read or write them over the REST API and MCP server.
What you get
- 26 field types
- Including lookup, calculated formula, currency, percent, rating, file, image and tag fields.
- Custom fields everywhere
- Add custom fields to standard records such as accounts, projects and invoices, not only to custom objects.
- Picklists you control
- Set the values for dropdowns so everyone picks from the same list.
- Required fields enforced
- Fields marked required in settings are enforced in the app and over the API.
- Ready for AI assistants
- MCP tools create objects, add records, search them and add comments, all under the user's permissions.
