Definition
An Account Assignment Rule is a rule within Sales Territories that automatically assigns Account records to specific territories based on predefined field criteria.
Real-World Example
Your company operates in multiple regions. You set up an Account Assignment Rule so that any Account with a billing address in the Western US is automatically assigned to Sarah, the West Coast sales manager, while accounts in the Eastern US go to James. When a new Account is imported via Data Loader, the rule fires and each record lands with the correct owner instantly.
Why Account Assignment Rule Matters
Account Assignment Rules live inside Enterprise Territory Management (or the older Territory Management feature) and evaluate Account field values against rule criteria to decide which territory an Account belongs to. Rules can use fields like BillingState, Industry, AnnualRevenue, or any custom field, and each rule is tied to a specific territory within a territory model.
Rules can be applied automatically when Accounts are created or updated, or run manually against existing Accounts by initiating an assignment run. When a territory model is activated, every Account is evaluated against the rules for that model, which means changing a rule can cascade into significant ownership and access changes across the org. Most teams test rules in a planning state before activating.
How Organizations Use Account Assignment Rule
- •Oceanic Corp — Uses Account Assignment Rules to route every new Account to the right geographic territory based on billing state. The West region has three sub-territories, and rules using BillingState and AnnualRevenue together ensure that enterprise accounts in California land with the strategic accounts team rather than the general West team.
- •Vandelay Industries — Built a complex set of Account Assignment Rules that combine industry and employee count to assign Accounts to vertical-specific territories. Healthcare accounts with more than 1,000 employees go to the healthcare enterprise team, while smaller ones route to the healthcare mid-market team.
- •Cyberdyne Co — Runs Account Assignment Rules manually once per quarter during a planning cycle. They preview the changes in a planning territory model, review the impact with sales leadership, and only then activate the model so that ownership changes happen on a predictable schedule.
