The Side Car Onboarding Playbook

Your new rep isn't struggling. Your onboarding is.

Why most HubSpot installs underperform, what a properly configured setup actually looks like for a business under $25M, and how to turn a tool your team tolerates into one they actually use.

Most owners put enormous effort into hiring the right person and almost no effort into what happens after they say yes. The rep shows up on Monday, gets a laptop and a login, meets the team, and is largely left to figure it out. Three months later the owner is wondering whether they made the right call. Usually they did. The onboarding just failed them.

Why onboarding fails and what it actually costs

Bad onboarding is expensive in ways that don't always show up on a spreadsheet. There's the obvious cost — a rep who takes six months to get productive when a good process could have done it in three. But there's also the hidden cost: a talented person who decides in week two that this isn't the right place and starts looking while still collecting a paycheque.

 

The two most common onboarding failures aren't complicated.

 

Failure one: no structure

The rep is handed a product sheet, introduced to a few colleagues, and told to "get familiar with things." There's no learning path, no milestones, no clear expectation of what good looks like at 30, 60, or 90 days. The rep does their best, which means they default to whatever they did at their last job, which may or may not fit how your business actually sells.

 

Failure two: too much information, too fast

The opposite problem. The owner dumps every piece of company history, product knowledge, and tribal knowledge into the first two weeks. The rep is overwhelmed, retains maybe 20% of it, and spends the next month quietly bluffing their way through gaps they're too embarrassed to admit they have.

The fix for both failures is the same: a structured, sequenced plan that prioritises what a rep needs to know first, builds on it deliberately, and checks understanding before moving forward.

The goal of onboarding isn't to transfer every piece of information you have. It's to get a rep to their first confident, independent sale as quickly as possible. Everything else can wait.

The four things every new rep needs before they can sell

01

The customer

Who buys from you, why they buy, what problem they're solving, and what the buying process looks like from their side. Not demographics. Context. Enough that a new rep can have a credible first conversation with a prospect without sounding like they started last week.

02

The product or service

Not the features list. The value. What does this thing actually do for the customer? What changes for them after they buy? A rep who can't answer those questions confidently isn't ready to sell, and no amount of enthusiasm makes up for that in a real conversation.

03

The process

How does your business sell? What are the stages? What moves a deal forward? What does a qualified prospect look like? Where does the CRM fit in? A rep who doesn't understand your process will invent one, and the one they invent will be based on wherever they worked before.

04

The expectations

What does success look like at 30, 60, and 90 days? What are they measured on during ramp? Who do they go to when they're stuck? These aren't administrative details. They're the foundation of a functional working relationship, and most owners never communicate them clearly.

If you don't have a documented onboarding process, you're reinventing it every time you hire.

Most owners onboard by feel, which works when you're hiring once every three years and have time to be hands-on. It stops working the moment you're too busy to babysit a new rep, or the person you hired needs more structure than your memory and good intentions can provide. Side Car builds onboarding frameworks as part of every engagement.

The 30-60-90 day framework

The 30-60-90 structure isn't just a planning tool. It's a communication tool. It tells the rep exactly what's expected of them and when, which removes ambiguity and gives both of you something concrete to have a conversation about at each milestone.

01

Day 1–30

Learn the business, the customer, and the process

This phase is about absorption, not production. The rep learns your product, meets your existing customers, shadows deals in progress, and gets comfortable in your crm. The milestone at 30 days isn't a number. It's a demonstration of understanding. Can they explain what you do and who it's for? Can they walk through a deal in your crm and describe what each stage means? if yes, they're ready for phase two.

02

Day 31–60

Start building pipeline and close first deals

This phase is about application. The rep starts prospecting independently, running their own discovery calls, and moving deals through the process with your support. What you're watching for: are they applying what they learned in phase one, are they asking good questions when stuck, and is their pipeline beginning to look like something real.

03

Day 61–90

Operate independently and hit ramp quota

This phase is about independence. The rep runs their own full cycle with minimal hand-holding, hits their ramp quota target, and demonstrates the habits that will make them successful long-term. By the end of day 90 you should have a clear picture of whether this person is going to succeed and what they specifically need to develop next.

The 30-60-90 plan only works if you actually review it at each milestone. A 30-minute check-in at day 30, day 60, and day 90 scheduled before the rep starts costs you 90 minutes. Not doing it costs you months of ambiguity and a potentially avoidable termination conversation.

What the first two weeks should actually look like

If you don't have a documented onboarding process, you're reinventing it every time you hire.

Day one: the basics. Laptop, logins, tools, introductions. Keep it simple. Don't try to teach anything substantive on day one. Days two and three: walk through your best two or three customer stories in detail. Who they were before they bought, what problem they had, what changed after. Days four and five: the product. How it works, what it delivers, how it's positioned. Have them demo it back to you by end of week one. Not perfectly. Just enough to show they understand it.

 

Week two: process and tools

Days six and seven: the sales process. Walk through each CRM stage, what it means, what moves a deal forward. Days eight and nine: live shadowing. They sit in on two or three real calls or meetings with you or your best rep. Debrief after each one. Day ten: their first outreach. They send their first prospecting emails or make their first calls, with you reviewing the approach beforehand. The goal isn't to close anything. It's to get them doing the actual job before the end of week two.

Most owners don't have the bandwidth to run onboarding this hands-on.

That's a real constraint. If you're still carrying deals yourself while trying to bring a new rep up to speed, something has to give, and it's usually the onboarding. Building a documented process means the rep can move through it independently and you're reviewing progress rather than delivering content. That's a much more manageable ask on your time.

How to tell if onboarding is working

Revenue in the first 90 days is a lagging indicator, especially if your cycle is longer than a few weeks. Here's what to watch instead.

Leading indicators of a successful onboarding

CRM discipline from day one. A rep who logs their activity consistently from the start is showing you they understand the process and respect the system.

Quality of questions. Early questions should be about understanding the business. Later questions should be about refining approach. If the questions aren't evolving, the learning isn't either.

Pipeline build rate. By end of week four a rep should have at least the beginning of a real pipeline. A rep with nothing at day 30 either hasn't been prospecting or doesn't know where to start. Find out which one immediately.

Comfort with the product story. Can they tell your customer story clearly and confidently without referencing notes? By day 30 the answer should be yes.

The 90-day review

Done properly it covers four things: what's working, what isn't, what the rep needs to develop in the next 90 days, and whether you both believe this is the right fit for the long term. That last part is harder to have but worth having early. A rep who has doubts at 90 days and doesn't feel safe surfacing them will still have those doubts at 180 days, and by then the cost of the conversation is significantly higher.

 

Onboarding isn't glamorous work. It doesn't feel like growth. It feels like administration. But the businesses that consistently build strong sales teams are almost always the ones that have taken the time to build a repeatable onboarding process, because it means every new rep gets a fair start and every hire decision gets a fair evaluation.

 

You spent real time and money finding the right person. Spend a fraction of that getting them set up properly. The return is faster ramp, lower turnover, and a team that actually knows how to sell the way your business needs them to.

The 90-day review isn't a performance improvement plan. It's a calibration. Done right, it either confirms you made a great hire or it surfaces a problem early enough to do something about it. Either outcome is better than finding out at month seven.

Want a rep who's productive in 60 days instead of six months?

If you're about to hire, or you've just hired and the onboarding feels like it's being made up as you go, it's worth a conversation. Building a solid onboarding process before the next hire is one of the highest-return things you can do with a few hours of planning.
