How to use 1:N relationships to link vendors to multiple payables without duplicating data

With an "n to 1" connection in Jestor, each vendor can be linked to several payables, but each payable points to a single vendor.

If you're looking to connect data across tables, tools like Jestor, Airtable (with linked records), and Notion (with relations) also offer this kind of connection, and that's where Jestor stands out: this connected field is already born integrated with the rest of the financial flow — automatic card creation, OCR, and ERP posting.

Why does a 1:N relationship between vendor and payables matter?

Without this relationship, a vendor's name, phone, email, and other data need to be retyped for every new payable logged, increasing the risk of errors and rework.

How to configure a 1:N relationship in Jestor?

• When adding a "connected records" column to the payables table, the "n to 1" option points to the vendors table.
• The field used as the label for this connection can be any field from the vendors table — name is usually the clearest choice.
• When filling out a new payable, you can select an already-registered vendor or create a new one right from there.
• In practice, this cuts down the need to retype a vendor's name, email, and phone every time a new invoice comes in.

To configure this connection:

1. In the payables table, add a column.
2. Choose "connected records" and select the n-to-1 relationship, pointing to the vendors table.
3. Define which field serves as the label (name is recommended).

Why choose Jestor to connect vendors and payables?

Having this native relationship avoids two sources of truth for the same vendor, and it still works alongside the rest of the financial process's automations and integrations.
