How do we comp reps on expansion/upsell deals when they're working alongside a CSM or account manager?

Split commission 50/50 AE and CSM/AM for expansion deals under $50k; AE takes 70/CSM 30 for $50k+ (CSM's relationship still matters, but AE drove the execution). Use a clear deal-source attribution matrix or reps will fight over credit. Expansion commission is where most teams create comp civil wars.

AE says she sourced it; CSM says she owned the relationship. Both think they deserve 100%. The fix: written attribution rules applied before the deal closes, not retroactively.

Expansion Deal Attribution Rules:

The Problem with "50/50" Default:

Most teams give CSM 30–50% on all expansion deals ("they own the relationship"). This incentivizes CSM to expand and AE to ignore expansion ("CSM will do it"). Result: expansion rate drops because AE doesn't hunt for it.

Better: AE gets 70%+ on expansion, CSM gets 20–30%. This keeps AE hungry for expansion while rewarding CSM for relationship health.

Commission Rate Structure (Expansion-Focused):

Assume: AE gets $15k commission on $100k new customer. CSM gets nothing on new customer (AE's close). Expansion rules:

• Expansion <$25k: AE 70% ($10.5k), CSM 30% ($4.5k). Small upsell; CSM's relationship work is supporting, not leading.
• Expansion $25k–$100k: AE 60% ($9k), CSM 40% ($6k). Medium expansion; more collaboration.
• Expansion >$100k: AE 50% ($7.5k), CSM 50% ($7.5k). Large expansion; partnership deal. Or: AE 55%, CSM 45% if AE drove discovery.

Why Tiered Attribution Works:

Small expansions ($10k–$25k) are usually CSM-sourced ("Hey, we see you're using Feature A heavily; Feature B solves your next problem"). AE's job is to negotiate and close fast. CSM gets a smaller cut because the heavy lifting was done by her over months. AE gets bigger cut because she converted the opportunity in 1–2 weeks.

Large expansions ($100k+) require both AE and CSM. AE needs to do discovery to uncover the $100k problem; CSM's relationship makes that discovery possible. They both own it, so 50/50 or close.

The Attribution Matrix (Best Practice):

Define these upfront in writing. When a deal enters CRM, mark the "expansion source":

1. CSM-Sourced: CSM logged the opportunity, CSM noted in CRM "customer asked about Feature X." AE picked it up from there.
2. AE-Sourced: AE discovered unmet need via executive conversation or proactive outreach. CSM supports closing.
3. Joint-Sourced: Both AE and CSM discovered the need; both had conversations with customer. Rare; treat as 50/50.
4. CSM-Closed: CSM closed the expansion deal directly (small upsells, feature add-ons, tier upgrades). No AE involvement. CSM gets 100%.

By marking source in CRM, you remove subjectivity. The deal is attributed at entry, not argued at payout.

Expansion Commission as CSM Performance Metric:

Most CSMs aren't measured on expansion revenue (AE's KPI). This creates misalignment. Better:

• CSM bonus: 50% on NPS/retention, 50% on expansion attach rate. "You own customer health. Healthy customers expand. Expand more, earn more." Pavilion data: CSMs with expansion-tied bonuses drive 25% higher expansion revenue than CSMs on pure retention metrics.
• AE bonus: 50% on new customer revenue, 50% on existing customer expansion. "You're a growth engine. New logos and expansion both matter." Forces AE focus on expansion account hunting, not just greenfield hunting.

The "Add-On" Exception (No Commission):

Small feature add-ons (third-party integration, extra storage, compliance module) that are part of the original contract negotiation don't warrant a new commission. These were priced into the original deal. Paying commission on add-ons incentivizes AE to undersell the original deal, then upsell the "add-ons" separately.

Don't do this. Add-ons are part of the base contract; no expansion commission.

Red Flags:

• CSM gets 50%+ on all expansion (disincentivizes AE expansion hunting).
• No written attribution rules; reps argue over credit on every expansion deal.
• Expansion commission calculated retroactively (after deal closes; invites disputes).
• Add-on features counted as expansion (inflates expansion metrics artificially).
• AE gets 100% on expansion, CSM gets nothing (CSM stops caring about expansion).

Example Scenario:

Customer bought $100k 3-year contract Year 1 (AE earned $15k commission). In Year 2, CSM identifies the customer needs advanced analytics module. CSM sets up meeting. AE negotiates; customer agrees to $30k add-on (one-year deal, renews separately from main contract).

• If split 50/50: AE $4.5k, CSM $4.5k. Both feel fairly compensated.
• If AE takes 100%: CSM is annoyed; she surfaced the need. She stops sourcing expansion.
• If CSM takes 100%: AE didn't participate in negotiation; she should get something. But if AE gets nothing, she ignores expansion.
• Correct approach: AE 70% ($6.3k), CSM 30% ($2.7k). CSM gets recognized for sourcing; AE gets majority for executing.

FAQ

How should expansion commission be split between the AE and CSM by deal size? The article's tiered structure pays AE 70% / CSM 30% on expansions under $25k, AE 60% / CSM 40% on $25k-$100k, and AE 50% / CSM 50% on expansions over $100k. Small upsells are usually CSM-sourced but AE-converted quickly, while large expansions require both parties doing discovery and relationship work.

Why is a flat 50/50 expansion split a problem? Giving the CSM 30-50% on all expansion deals incentivizes the AE to ignore expansion ("CSM will do it"), which drops the expansion rate because the AE stops hunting for it. The article recommends keeping the AE at 70%+ on most expansion so they stay hungry, while still rewarding the CSM 20-30% for relationship health.

How does the attribution matrix remove credit disputes? At deal entry in CRM you mark the expansion source as CSM-Sourced, AE-Sourced, Joint-Sourced, or CSM-Closed. Because the deal is attributed at entry rather than argued at payout, subjectivity is removed and reps don't fight over credit retroactively.

Why are add-on features excluded from expansion commission? Small add-ons like third-party integrations, extra storage, or a compliance module that were part of the original contract negotiation don't warrant new commission because they were already priced into the original deal.

Paying commission on add-ons would incentivize the AE to undersell the original deal and then upsell the "add-ons" separately.

How should CSM bonuses be structured to drive expansion? The article recommends a CSM bonus split 50% on NPS/retention and 50% on expansion attach rate, framed as "healthy customers expand; expand more, earn more." It cites Pavilion data that CSMs with expansion-tied bonuses drive 25% higher expansion revenue than CSMs on pure retention metrics.
