Territory design is not an HR exercise. It is a revenue architecture decision. A territory that gives one rep 200 high-fit accounts and another rep 30 low-fit accounts does not create a fair test of rep performance -- it creates a confounded experiment where the territory determines the outcome more than the rep.
Step 1: Define the territory unit
Territories can be defined by geography, by vertical, by account size, or by named accounts. Each has different trade-offs.
Most B2B SaaS companies at 20-100 rep scale use a hybrid: named accounts for enterprise, segment-based for mid-market, and geographic for SMB. Define the unit per segment before assigning accounts.
Step 2: Size and balance territories
A territory is balanced when every rep has a comparable opportunity -- not the same number of accounts, but the same realistic pipeline potential.
The balancing formula:
Territory value = (Number of ICP accounts x Average win rate x Average ACV x Estimated purchase probability)
Run this calculation for each territory candidate and adjust until territories are within 20% of each other on expected pipeline value. Perfect balance is not achievable, but 20% variance is the threshold below which reps stop complaining about territory fairness.
Balancing considerations:
Step 3: Assign and document
Territory assignment is a political as well as analytical exercise. The process must be transparent and the rationale documented.
Step 4: Review and rebalance
Territory strategy health checklist
"Sales teams that conduct an annual territory rebalancing exercise report 18% lower rep turnover in the 12 months following the redesign compared to teams with static territories."
