Account Mix is a new Smart Plan criteria type that lets you define the exact composition of each territory's book of business. Unlike standard balancing (which distributes accounts evenly across territories) Account Mix enforces a specific percentage breakdown per territory, giving you deterministic control over what goes into each rep's book.

Why Account Mixes?
Traditional Smart Plan balancing is excellent at distributing accounts evenly—take your Tier A accounts and split them equally across six territories. But even distribution isn't always the goal. Organizations are moving toward more nuanced territory design for several reasons:
Role Specialization: You may want to experiment with industry verticals—such as manufacturing, retail, or financial services—without fully committing a rep to a single vertical. Account Mix lets you make finance 70% of a rep's book while keeping a diversified remainder.
Seniority and Quota Alignment: Senior reps carry higher quotas and need more high-potential accounts. Junior or ramping reps need a different composition. Account Mix lets you prescribe different mixes for different territories based on who will cover them.
Deterministic Control: Rather than letting the system optimize for balance, you define exactly what percentage of each account type belongs in each territory, because you know the rep, the strategy, and the business goal behind each book.
The Math: Percentage-First Logic and Bottlenecks
Account Mix uses percentage-first logic, meaning the system prioritizes maintaining the percentage mix you define for each territory above all else. This has a direct impact on how many accounts end up in each territory.
How It Works
Define your groups. Segment your accounts into groups using filtering criteria (e.g., by industry: Finance, Education, HLS, Services, Other).
Set your percentages. For each territory (book), specify what percentage of accounts should come from each group. Percentages must add up to 100% per territory.
The system identifies the bottleneck. The group with the fewest available accounts relative to the percentages you've set becomes the limiting factor. For example, if you only have 55 finance accounts but want 50% of each territory to be finance, finance is your bottleneck.
A maximum account count is calculated per territory. The bottleneck determines how many total accounts can exist in each territory while still honoring all percentage requirements.
Determine what to do with remaining accounts. Remaining accounts can either go to the unassigned node or be distributed evenly. Choosing to allocate remaining accounts to unassigned ensures that the percentage mix is not violated..
Example
Group | Available Accounts |
|---|---|
CPG | 200 |
Finance | 55 |
Retail | 150 |
Other | 500 |
If you are building 4 territories and the bottleneck calculation yields a maximum of 92 accounts per territory, each territory receives accounts according to its defined percentages applied to that 92-account cap (e.g., 25% of 92 = 23 CPG accounts).
Key takeaway: If you find your territories have fewer accounts than expected, check two things: how many accounts exist in each group, and what percentages you've defined. The interaction between these two factors determines territory size.
Use Case 1: Industry Specialization
What it is: You want to create territories with a dominant industry focus—essentially building "major-minor" territories where a rep specializes in one industry while maintaining exposure to others.
Why it matters: This approach lets you test industry verticals without fully pigeonholing reps. A rep with a finance background can have 70% of their book in finance while still covering other industries. Meanwhile, the majority of your finance accounts are managed by someone who specializes in that business.
How it works:
Add the Account Mix criteria to your Smart Plan. You can only add one Account Mix criteria per Smart Plan, but different Smart Plans (e.g., Enterprise vs. Growth) can each have their own unique Account Mix configuration.
Define your account groups using filtering criteria. Groups are prioritized top-to-bottom—accounts matching the first group are allocated first, then the second, and so on. A group with no filtering criteria acts as a catch-all for everything remaining.
Set the percentage mix for each territory. For example:
Enterprise 1 (Finance Focus): 50% Finance, 20% HLS, 10% Education, 20% Other
Enterprise 2 (HLS Focus): 20% Finance, 50% HLS, 20% Education, 10% Other
Run the Smart Plan. The system enforces the percentage mix, calculates the bottleneck, and distributes accounts accordingly.
Note: The filtering criteria for account groups supports the same AND/OR filter builder available throughout Fullcast. Any field enabled for hierarchy participation can be used—not just text fields. This includes numeric fields with range-based criteria (e.g., Customer Fit Score between 3 and 4, or Employee Count between 150 and 250).
Use Case 2: Fit Score Balance (Seniority / Quota Alignment)
What it is: You band accounts into groups based on a score or potential metric (e.g., high, medium, and low customer fit), then assign different mixes to territories based on rep seniority or quota targets.
Why it matters: Senior reps with $1M quotas need more high-potential accounts. Ramping reps with $750K quotas need a different composition. Account Mix lets you build these differentiated books systematically rather than through manual adjustments.
How it works:
Create account groups using banded criteria on a score field (e.g., Customer Fit Score: High = 8–10, Medium = 4–7, Low = 1–3).
Set different percentage mixes per territory:
Growth 1–3 (Senior Reps): 60% High Fit, 40% Medium Fit, 0% Low Fit
Growth 4–6 (Ramping Reps): 30% High Fit, 40% Medium Fit, 30% Low Fit
Run the Smart Plan. Senior rep territories receive a higher concentration of high-fit accounts, while ramping reps receive a more balanced mix with lower overall potential.
Additional use cases raised during the session:
Renewal date balancing for CS teams: Use Account Mix to ensure no single CSM has 90% of their accounts renewing in the same quarter, preventing burnout during peak periods.
Cross-sell product mix: When managing multiple product lines (e.g., after acquisitions), ensure each CSM's book includes accounts across different products to enable cross-sell opportunities while still weighting toward their area of expertise.
Use Case 3: Tier-Based Distribution
What it is: You group accounts by tier (e.g., Tier A, Tier B+C combined, Tier D) and distribute them with specific percentages per territory.
Why it matters: This approach is useful when you want to reserve some high-tier accounts—for example, holding back Tier A accounts for a future hire or for inbound assignment—rather than distributing all of them immediately.
When standard balancing may be better: If your goal is simply to split Tier A accounts evenly across all territories with no accounts left unassigned, the standard Balance by number of accounts criteria filtered to Tier A is likely a better fit. Account Mix is most valuable when you intentionally want to limit territory size or create differentiated compositions.
Account Mix vs. Weight By: Understanding the Difference
A common question is how Account Mix differs from the existing Weight by number of accounts criteria. The distinction is fundamental:
Account Mix | Weight By Number of Accounts | |
|---|---|---|
Perspective | Centered on the individual territory (the book) | Centered on the total pool (the whole world) |
What the percentage controls | The composition of each territory—e.g., 50% of this territory's accounts will be finance | The distribution of a group across territories—e.g., 90% of all finance accounts go to Enterprise 1 |
Unassigned accounts | Accounts may remain unassigned to enforce the mix | All accounts in the group are distributed |
Best for | Prescriptive book composition where you know exactly what each territory should look like | Distributing a known pool of accounts unevenly across territories without strict per-territory composition requirements |
When to use which:
If your goal is a specific, predefined bar chart for each territory—"I want exactly 60% high-fit and 40% medium-fit in this book"—use Account Mix.
If your goal is to ensure all accounts of a certain type are assigned, and you want to control how they spread across territories—"Give 90% of my finance accounts to Enterprise 1"—use Weight By.
If you simply want accounts split evenly, use the standard Balance by number of accounts criteria.
Net New Accounts and Ongoing Maintenance
A key consideration when using Account Mix is how net new accounts are handled after the initial plan is run.
With Minimize Disruption enabled: If a net new account is already assigned in Salesforce and Minimize Disruption is turned on, the account will be placed into its assigned territory regardless of the mix.
Without Minimize Disruption: If a net new account hasn't been assigned and the territory's cap for that account type has already been reached, the account will go to unassigned.
Auto-rerun rules: If configured to run only on net new accounts, the system will place individual accounts as they arrive. However, this may not recalculate the full mix.
Recommended approach for net new accounts: Pair Account Mix with account routing using a round robin policy at the parent territory level. This distributes net new accounts fairly across territories without disrupting the original mix.
Quarterly reshuffles: If you periodically rebalance territories, rerunning the full Smart Plan is the better approach. This allows the system to recalculate the bottleneck, honor minimize disruption for existing assignments, and redistribute accounts according to the updated mix.
Important Considerations
One Account Mix per Smart Plan: You can only add one Account Mix criteria per Smart Plan configuration. However, different Smart Plans at different levels of your hierarchy (e.g., Enterprise, Mid-Market, Growth) can each have their own unique Account Mix.
Interaction with other balancing criteria: Adding additional balancing criteria (such as Balance by ARR) beneath an Account Mix criteria can disrupt your percentage mix. Account Mix is a strategic choice—use it when the composition of each book is your primary objective, and avoid layering conflicting balance criteria.
Distribute remaining accounts: A checkbox option exists to distribute unassigned accounts evenly across territories after the mix is applied. Be aware that enabling this will change the effective percentages in each territory, since the topped-up accounts won't follow the original mix ratios.
