Why do B2B buyers regret a purchase? Regret is earned after signing

Most B2B buyers don't regret the vendor they chose. When they do, the cause is usually what happened after the contract, not the decision itself.

Key findings

  • 59% of B2B buyers report low regret about the vendor they chose. 9% report significant regret.
  • 64% report at least some regret.
  • Among them, the top four causes are all post-sale: pricing crept up at renewal (15%), under-resourced implementation (12%), onboarding that fell short of the pitch (12%) and slower adoption than expected (11%).

How many B2B buyers regret their purchase?

Few, strongly. We asked 250 B2B buyers to rate their regret about the vendor they chose from 1 (none) to 5 (significant). More than a third (36%) report none and 23% give it a 2. Together, 59% report low regret.

At the top of the scale, 9% report significant regret and a further 16% give it a 4.

What causes buyer regret?

Delivery. Among the 161 buyers who report any regret, the most common single cause is pricing creeping up at renewal (15%). Under-resourced implementation and onboarding that fell short of the pitch follow on 12% each, with slower adoption than expected on 11%.

Those four account for half of all regret. The other half is spread across more than ten smaller reasons.

Half of all regret comes from four post-sale gaps

Is regret about choosing the wrong vendor?

Mostly not. None of the top four causes is "we picked the wrong product". They are about what happened next: the price changed, the implementation team was thin, the onboarding didn't match the pitch, people didn't use it.

These are gaps between what was sold and what was delivered. Any vendor can fall into them.

What this means

Sales wins the customer. Delivery decides whether they regret it.

Three of the four causes are within a vendor's control before the contract is signed.

  1. Pricing at renewal. If the year-two price is going to rise, say so in year one. A surprise is what turns a price increase into regret.
  2. Implementation resourcing. Put the people who will deliver in the room before the sale closes.
  3. Onboarding against the pitch. Compare the sales deck with the onboarding plan. Where they differ, the customer will notice.

The commercial stakes are direct. Regret is what makes a customer open to switching at renewal, and what stops them recommending you to a peer.
