Key Highlights

  • Bad sales hires must be identified within 90 days: Keeping poor performers too long multiplies opportunity costs beyond lost income when business gets lost in the field, making early detection critical.
  • Measure behavior, not just results: Track punctuality, customer visit frequency, networking event attendance, and lead follow-up—these KPIs reveal work ethic and selling appetite long before quota attainment.
  • Beware the "beautiful CRM" red flag: Salespeople with perfect CRMs, excessive training hours, and heavy AI tool usage but few customer meetings likely have sales reluctance.

Knowing if a new salesperson will work out or not is a challenge. Many sales managers hesitate “to cut bait yet,” but this thought process can be very expensive.

A good sales hire should start to pay for themselves in 9-12 months, and provide a return on the investment at about the two-year mark. That said, sales leaders must be able to identify a bad hire within 90 days.

Why? Because a bad sales hire early can deliver an opportunity cost multiple times higher than the income lost. Beyond losing the investment in the employee, the risk is multiplied when that bad sales hire is in the field too long, and business gets lost.   

Thus, spotting the warning signs of a bad sales hire becomes incredibly important. Here are four ways to do it as soon as possible:  

1. Establish sales-specific onboarding:

Depending on the complexity of solutions and customers, a proper onboarding program for new salespeople should last 3-6 months, with the goal being that salespeople are driving fully ramped activity levels at the end of the program. Sales onboarding shares knowledge quickly and puts new salespeople in front of customers within a couple of weeks.

If a salesperson hasn’t gotten in front of many potential customers during their first six months but their CRM is perfect, look deeper – it is likely they have a reluctance to sell.

New salespeople should work with installers, technicians, other salespeople, and their boss, getting various perspectives. This type of specific onboarding program will accelerate their performance and help to quickly reveal weaknesses that can lead to long-term failure.

2. Measure everything from day one:

The argument to keep poor-performing salespeople is that the sales process can be very long, since most salespeople don’t consistently reach their monthly sales targets for at least a year. While this is valid, numerous other things can be measured.

Of course, there are KPIs like the number of quotes delivered, but there are also assignments like visiting current customers, attending networking events, following up on leads, etc.

Here’s a simple KPI: Measure how frequently a new salesperson is on time to meetings during the first month. This will give you a glimpse of the type of performance you will receive in the future.

3. Have them follow up with friendly accounts during the first three months: 

Since they are friendly accounts where you already have an established relationship, it will be easier to learn how they managed communication, how responsive they were, and how hungry they are.

4. Beware of a beautiful CRM:

If a salesperson hasn’t gotten in front of many potential customers during their first six months but their CRM is perfect, look deeper – it is likely they have a reluctance to sell. They will find every excuse to avoid being face-to-face with potential customers.

Beyond the CRM, watch for new salespeople who are doing excessive training classes, spend a lot of time with technology partners, or are using AI tools like a pro. That probably means you have found a very sharp professional who may not be a great salesperson.
