Commission Splits: When and How to Split Sales Credit

Two reps both claim credit for the same deal. The AE closed it. The SDR sourced it. The sales engineer spent 12 hours on the technical validation. All three think they deserve commission.

This is where commission splits happen—and where commission disputes are born.

A commission split divides sales credit between multiple people involved in closing a single deal. Done well, splits recognize real contributions and reduce conflict. Done poorly, they create more disputes than they prevent.

Here's how to design them so they land in the first category.

What a commission split is

A commission split is an arrangement where the commission from a single closed deal is divided between two or more people. The total commission pool stays the same—it's just distributed across multiple recipients instead of one.

Example:

A deal closes at $80,000 in annual contract value. The commission rate is 10%, generating $8,000 in commission. If the deal is split 70/30 between an AE and an SDR:

The company pays out $8,000 either way. The split just determines who gets what.

Overlays work differently (more on that below)—the specialist's commission comes from a separate budget and doesn't reduce the primary rep's payout.

When commission splits come up

SDR/AE splits

The most common split in B2B SaaS. The SDR sources the lead, runs outbound, and books the discovery call. The AE runs the sales cycle and closes the deal.

Most companies handle this one of two ways:

Percentage split: The SDR receives a portion of the AE's commission on sourced deals. Common ranges are 10-20% to the SDR, 80-90% to the AE.

Flat sourcing bonus: The SDR receives a fixed amount per deal closed (e.g., $200 per closed deal), regardless of deal size. Simpler to track, easier to budget—but doesn't scale with large deals.

Neither approach is universally better. Percentage splits create more upside for the SDR on large deals, which helps with retention. Flat bonuses are easier to explain and calculate.

Co-sell arrangements

Two AEs collaborate on a single deal—often when a deal spans multiple territories, involves a strategic account with relationships from both sides, or requires expertise that one rep doesn't have.

Co-sell splits are often negotiated deal-by-deal, which creates problems. When the split isn't agreed upfront, it usually gets contested after close. The rep who did more work (subjectively) feels underpaid; the other rep disagrees.

The fix is a default co-sell policy: if two reps co-sell without a documented split agreement, the default is 50/50. That default creates an incentive to agree on the actual split upfront, which is the desired behavior.

Territory splits

When a customer spans two territories—a subsidiary in one rep's territory that's owned by a parent in another—the territory assignment determines commission credit. If both territories are involved in the sale, a split acknowledges both reps' contributions.

Territory splits get complicated fast. If your CRM doesn't enforce clean territory rules, you'll find yourself resolving these disputes manually at every close.

Channel and partner splits

When a deal involves a channel partner or reseller, the direct rep who supports the partner and the partner themselves may both receive some form of credit. The exact structure depends on how your channel program is set up, but the same principle applies: define who gets what before the deal closes.

How to set split percentages

There's no universal formula, but a few principles help:

Weight the split toward the quota-carrying role. The AE has more financial exposure—if the deal doesn't close, they miss quota. That accountability should be reflected in the split. SDRs and overlays typically receive smaller percentages because their income isn't quota-dependent in the same way.

Consider deal complexity. A simple inbound deal that a junior SDR ran into discovery doesn't warrant the same SDR credit as a complex outbound sequence that created an opportunity from scratch. Some companies use a tiered SDR split based on how the lead was sourced:

Keep it simple enough to explain. If a rep needs a spreadsheet to figure out what they'll earn from a split deal, the split policy is too complex.

Overlays: a different model

An overlay is not the same as a commission split. When a sales engineer or solutions consultant supports a deal, their compensation typically comes from a separate budget—it doesn't reduce the AE's payout.

Example:

An AE closes an $80,000 deal at 10% commission = $8,000. A sales engineer who supported the deal receives an overlay of 2% on deals they're involved in = $1,600. The company pays $9,600 total, not $8,000 split between them.

This matters for morale. AEs who see their commission reduced every time an SE is involved will start avoiding SE support—which is the opposite of what you want. Overlay budgets solve that problem by keeping the incentive structures clean.

The tradeoff is cost: overlay commissions add to total comp spend on every supported deal. You'll want to model this when designing the program, not discover it at close.

The edge cases that cause disputes

Define these before they happen:

Deal falls through after split commission is paid. If the deal cancels in month 2 and you clawback the AE's commission, do you also clawback the SDR's split? Almost always yes—but write it down.

One rep leaves before the deal closes. If an SDR books a deal that closes three months later, after the SDR has left the company, do they still receive the sourcing credit? Most companies say no (the departed rep is no longer in the system), but this needs to be explicit.

Disputed sourcing credit. The AE says the SDR didn't actually source the deal—they connected a warm inbound lead that the AE had already touched. Document what counts as "sourcing" in your CRM: a logged outbound sequence, a booked meeting, or a specific stage transition.

Territory changes mid-deal. A rep is reassigned to a different territory while their deal is still open. Does the commission go to the original rep or the new one? In most cases, the original rep should get credit for work done under their territory assignment. Set this as the default.

Documenting splits

Verbal split agreements cause disputes. The only reliable way to prevent them is to document splits at the deal level, not as a general policy that's open to interpretation.

What to record per deal:

• Deal ID and close date
• Each participant and their split percentage
• What triggered the split (sourcing, co-sell, territory)
• Total commission and each person's share

Your CRM is the right place for this, not a side spreadsheet. If you're running split policies, the split percentage should be attached to the opportunity record before the deal closes.

Tracking split commissions

The operational complexity with splits is that every calculation now involves multiple people, multiple payout amounts, and potentially different plan types. An SDR on a flat commission rate splitting a deal with an AE on a tiered plan means two separate calculations on the same deal.

In a spreadsheet, this means cross-referencing rep tables, deal tables, and split percentage tables for every payout. When deals are retroactively adjusted or clawed back, those changes need to flow through to every affected rep.

Tools like Carvd let you define split rules per deal or per rep relationship, so each person's payout is calculated automatically from the same underlying deal data. If the deal is adjusted, both reps see updated numbers—no manual recalculation.

That traceability matters. Reps involved in split deals are the most likely to run shadow accounting, because they can't easily verify that the split was applied correctly. Transparent calculations that show exactly how each person's number was derived are the fix.

Common mistakes

Defining splits after a deal closes. This always leads to negotiation under pressure, with both reps arguing for more. Set split policies before the quarter starts, not in response to specific deals.

Too many split tiers. If your SDR split policy has five categories based on lead source, stage of first meeting, and deal size range, no one will remember it. Two or three categories max.

Not accounting for splits in comp modeling. If you've designed an AE plan at a 10% commission rate and 40% of deals have a 20% SDR split attached, the effective commission rate for the average AE isn't 10%—it's closer to 8%. Model this before you launch the plan.

Using splits to avoid hard territory decisions. If two reps are fighting over a territory and the "solution" is a permanent 50/50 split on all deals in that region, you haven't solved the territory problem—you've just deferred it. Splits are for acknowledging real collaborative contributions, not for avoiding organizational decisions.
