Territory Planning for Small Sales Teams

Territory planning is really capacity planning with a map attached. The question is not "how do we divide the country" but "how many accounts can one rep work properly, and how do we allocate them so that nobody is starved and nobody is drowning." Get this wrong and your commission plan, forecast and coaching all inherit the error.

Start with capacity, not geography

Work out how many accounts a rep can genuinely cover before deciding how to group them.

Worked example. A rep has roughly 200 selling days a year after holiday, training and admin. Say each active account needs about four meaningful touches a quarter, and a rep can manage around 12 substantive customer interactions a day across calls, meetings and considered follow-ups.

• Annual interaction capacity: 200 x 12 = 2,400
• Reserve 40% for existing customers, proposals and internal work: 1,440 available for territory coverage
• At 16 touches per account per year: 1,440 ÷ 16 = 90 accounts

Ninety accounts, not the 400-name list somebody exported last year. Change the assumptions to match your business — a transactional product with a two-week cycle supports far more, a six-month enterprise cycle far fewer — but do the calculation rather than guessing. The discipline is in stating the assumptions out loud, where they can be argued with.

Four ways to split, compared

For most UK teams under ten reps, vertical or named-account splits beat geography. Territory is largely a legacy of field sales and travel time; if your team sells mostly by video and phone, dividing by sector gives you a rep who can talk credibly to a housing association and another who understands manufacturing, which is worth more than a tidy map.

Balance on three axes, not one

Equal account counts are not equal territories. Score each proposed patch on three measures and compare:

1. Potential — total addressable spend, not number of names. Twenty large accounts can outweigh 200 small ones.
2. Existing revenue — what the patch already bills. A patch with a large embedded base is a different job from a greenfield patch, and should carry a different target and possibly a different commission split.
3. Workload — accounts requiring active coverage. Renewals, support-heavy customers and long procurement cycles all consume time that produces no new revenue.

Aim for patches within roughly 15% of each other on potential — a working tolerance, not a researched threshold. Perfect balance is not achievable and chasing it wastes weeks; visible unfairness is what causes damage.

A worked allocation

A team of three selling into UK professional services, with a qualified universe of about 270 accounts and a £900,000 new business target.

• Capacity says 90 accounts each, so the universe divides cleanly — that is unusual and worth checking. If it did not divide, the answer is to cut the universe by tightening the ideal customer profile, not to give everyone 130 accounts.
• Split by sub-sector: accountancy and finance; legal; consultancies and agencies.
• Check potential: if legal holds 45% of the addressable spend, that patch needs fewer accounts, not the same number.
• Rebalance to roughly equal potential, then set targets from that potential rather than dividing £900,000 by three.

That last point is where many plans fall over. Equal targets across unequal patches is a very common territory mistake, and no commission design compensates for it.

Rules you need in writing

Territory disputes are corrosive and almost entirely preventable. Write these down before anyone needs them.

• Ownership. An account belongs to whoever holds the patch it sits in, not whoever spoke to them first, unless there is an open opportunity.
• Inbound leads. Route by territory rule, automatically, with no manual allocation. Manual allocation is where favouritism is perceived whether or not it exists.
• Multi-site and group companies. Decide in advance: usually assigned by head office location or by the entity that signs.
• Open opportunities on reassignment. A deal past proposal stage typically stays with the original rep to close, with commission split or protected for an agreed period.
• Dormancy. An account with no meaningful contact in a defined period — six or twelve months — returns to the pool. Without this, patches silently become private property.
• Review cadence. Annually, announced in advance. Surprise reassignments are read as punishment, whatever the intent.

When someone leaves or joins

Adding a fourth rep to a three-rep team means taking accounts from people who were counting on them. Handle it badly and you demotivate three people to enable one.

• Announce the intent to split before recruiting, not after the new starter arrives
• Protect in-flight deals in the affected patches for a defined period
• Reduce the existing reps' targets in proportion to the potential removed — if a patch loses 30% of its potential, the target must move, or you have given someone a pay cut
• Give the new rep a patch with some existing customers rather than pure greenfield, unless the ramp plan explicitly accounts for a long dry period; the 30/60/90 plan should reflect whichever you choose

Where territory planning breaks on very small teams

With two reps, formal territories often cost more than they return. The overhead of rules, routing and disputes outweighs the benefit when both people could cover the whole market. The useful minimum for a two-person team is: a shared, tightly defined ideal customer profile, a single owner per named account recorded in the CRM, and a dormancy rule. Nothing else.

The trigger for real territories is usually the third or fourth rep, or the first time two people turn up to the same prospect in the same week. Do not build the machinery before you need it — but do record account ownership from day one, because retrofitting ownership onto a messy database is a genuinely unpleasant job. If you are already in that position, cleaning up the CRM comes before territory design, not after.

The annual review

Once a year, ask four questions:

1. Did every patch have enough potential to make target, or did someone miss because of allocation rather than performance?
2. How many accounts in each patch had no contact at all? High numbers mean patches are too big, not that reps are lazy.
3. Has the market moved? A sector that grew or contracted sharply changes the balance regardless of what you decided last year.
4. Are the ownership rules being applied, or quietly worked around?

Then feed the answer into next year's quotas before the commission plan is published, not after. Territory, quota and commission are one decision made in three parts, and making them in the wrong order is why so many plans feel unfair to the people living under them.
