A partner called me last year, furious, because a rep from the ISV he represented had cold-called one of his existing clients to pitch a new module directly. The rep didn't know the account belonged to a partner. Nobody had told him to check. The VAR found out because the client called him confused, asking why two people from the same vendor were suddenly pitching him different things.
That partner didn't quit the relationship. But he stopped bringing new deals for about five months while he decided whether it was worth the risk of it happening again. That's the real cost of channel conflict. It's rarely one blown deal. It's the partner quietly deprioritizing you afterward.
Why this happens even at companies that mean well
Almost no ISV sets out to compete with its own partners. It happens because direct sales and channel sales grow up as separate motions with separate incentives, and nobody draws a boundary between them until there's a collision. Direct reps are comped on closed revenue. If an account looks reachable and nobody flagged it as a partner's, a rep with a quota to hit is going to call it. That's not malice. That's the comp plan doing exactly what it was built to do, just in the wrong account.
The other common version is subtler: an ISV runs a marketing campaign, inbound leads come in, and direct sales gets first crack at anything that lands in the CRM regardless of whether a local VAR already has a relationship with that company. Partners find out when the deal shows up closed under someone else's name.
Deal registration is the fix, but only if it's enforced
Deal registration exists to solve exactly this problem, and most ISVs have some version of it. The gap is enforcement. A deal registration system that partners can submit to, but that doesn't actually block a direct rep from working the same account, is a policy on paper and nothing else. It needs teeth. That means the CRM itself should flag a registered account before a direct rep spends time on it, not just a spreadsheet someone's supposed to check.
Registration windows matter too. Thirty to ninety days is typical, tied to real partner activity, not just a name entered into a form. A partner who registers an account and then does nothing with it for four months isn't protecting a real opportunity. But a partner actively working a deal deserves real protection, and that protection needs to survive contact with your direct sales team's quota pressure.
Segment the market instead of fighting over every account
The programs that avoid conflict entirely usually don't rely on registration as the only mechanism. They segment upfront. Maybe direct sales owns enterprise accounts above a certain size, and partners own everything in the mid-market. Maybe direct owns a named list of strategic accounts and partners get the rest of the territory. Maybe new logos in a partner's geography default to the partner unless the partner passes on it.
Whatever the line is, it has to be clear enough that a rep can check it in under a minute, and it has to be something you're willing to hold to when a juicy account happens to land on the wrong side of it. The segmentation doesn't need to be permanent. Review it once or twice a year as the business changes. But it needs to exist as a real rule, not a vague understanding that gets reinterpreted every time a big deal is on the table.
Marketing needs to be part of the policy, not just sales
Channel conflict doesn't only come from a rep dialing the wrong account. It comes from marketing running a campaign that generates inbound leads with no awareness of which accounts belong to a partner, then routing every lead straight to direct sales because that's simply how the lead workflow was built. A partner finds out their client got a marketing email offering a discount that undercuts the deal the partner is actively working. Fix this by connecting your CRM's account ownership data to your marketing automation, so a lead from a partner's registered account routes back to that partner, or at minimum flags for a manual check before anyone reaches out. This is a five-minute conversation with whoever owns your marketing stack, and it closes a leak most ISVs don't know they have until a partner complains about it.
When conflict is actually a comp problem
If direct reps keep encroaching on partner accounts despite a clear policy, look at what they're paid to do. A rep with a number to hit and no incentive tied to channel health will rationally chase whatever's in reach. Some ISVs solve this by crediting a direct rep for facilitating a warm handoff to a partner, so there's an upside to routing the deal correctly instead of just an instruction to leave it alone. Others build channel neutrality into how territories are scoped from the start, so the temptation never comes up.
None of this needs to be complicated. It needs to be explicit, it needs a system behind it instead of goodwill, and it needs someone senior enough to enforce it when a rep pushes back because a partner account looks like an easy close. The ISVs I've seen with healthy channels aren't the ones with zero conflict. They're the ones where a partner who gets stepped on knows exactly who to call, and knows the issue actually gets fixed instead of smoothed over.
