When Debug Pest Control was a ten-person shop, a new technician could shadow a colleague for a month and turn out fine. By the time the Rhode Island company had grown past 50 employees, that same "trial by fire" had quietly become the training program — and a new hire's first weeks looked completely different depending on which technician they happened to be paired with. Same trucks, same crew, wildly different starts. At 15 employees, that sorts itself out. At 50, it's how everyone gets trained.
Once a company passes 50 employees, the informal onboarding that worked at 15 stops working. The founder can no longer train everyone personally, and "shadow someone for a week" produces 50 different versions of the job. The best way to onboard and train new hires past 50 employees is to make the process explicit: document how each role actually works, give every hire a clear role-based path, and track completion so nothing gets skipped. Below is the step-by-step process for building that, what a complete onboarding process should include, and where a tool starts to help once you outgrow spreadsheets and tribal knowledge.
What changes at 50 employees
Nothing breaks on the day you hire your fiftieth person. What changes is that the shortcuts stop holding:
- One person can't train everyone anymore. The founder or first manager who used to onboard each hire personally is now a bottleneck — or absent from the process entirely.
- The job lives in people's heads. How work actually gets done is tribal knowledge, and it walks out the door every time someone leaves or gets busy.
- Everyone learns a slightly different version. Without a written source of truth, each new hire inherits whoever happened to train them — inconsistencies compound with headcount.
- You can't see what's been covered. "Did anyone show them how to do X?" has no answer, so gaps only surface when something goes wrong.
The fix is not more orientation. It is making the process explicit, repeatable, and trackable — the same shift from "50 to 100 employees" that every scaling company runs into.
The step-by-step process to onboard past 50 employees
1. Write down how each role actually works
Start with the roles you hire into most. Capture the real steps, tools, and decisions of the job as documented SOPs — not a job description, but how the work gets done. This is the source of truth every hire will train from.
2. Build a role-based path, not one generic checklist
A warehouse hire and a sales hire should not get the same onboarding. Give each role its own onboarding path so people spend time on what their job needs and skip what it doesn't.
3. Map the first day, first week, and first 90 days
Day one is logistics and access. The first week is team, tools, and the shape of the role. The first 30–90 days is where someone actually becomes competent. Plan all three, not just orientation day.
4. Assign an owner to every part
Each piece of onboarding needs a name attached — who delivers it, who answers questions. Ownership is what keeps a documented process from quietly going stale.
5. Confirm understanding, not just completion
A checked box means someone opened a page, not that they can do the job. Build in a quick check — a question, a task, a sign-off — so you know the training landed.
6. Keep it current
Processes change. Review the most-used paths on a set cadence so the documented version stays the real version — otherwise new hires learn the outdated one.
Where a tool helps — and where it doesn't
Be honest with yourself about the stage you're at. For the first 20 or so people, a shared doc and a checklist genuinely work; adding software before you need it just adds overhead.
Past 50 employees, the informal version usually breaks in a specific way: spreadsheets go stale, the source of truth is whoever trained you, and no one can say who's been trained on what. That's the point where a tool earns its place. Trainual is built for exactly this — it lets you document how each role works, build role-based onboarding paths, and track completion and understanding, so the process survives past the people who created it.
The shift is measurable. After Debug Pest Control replaced shadowing with documented, role-based paths, it cut technician ramp time from six-to-eight weeks down to three-to-four — and about 90% of that training now happens on mobile, which is how a field crew in trucks all day actually learns.
The test is simple: if you can't say who was trained on what, or every new hire gets a slightly different version of the job, you've outgrown the informal approach.

Frequently asked questions
What is the best way to onboard and train new hires at a company that just passed 50 employees?
Make the process explicit instead of informal. Document how each role actually works, give every new hire a role-based path rather than one generic checklist, cover the first day through the first 90 days, assign an owner to each part, and track completion so nothing gets skipped. Below about 20 employees a shared doc and a checklist can carry this; past 50, that informal approach produces inconsistent training and gaps, which is why companies at this stage move to a documented, trackable process.
What should be included in a full employee onboarding process?
Five things: company and culture (mission, values, and how decisions get made); role clarity (what good looks like for this specific role); tools and access (systems, logins, and who to ask); process and SOPs (how the actual work gets done, step by step); and checkpoints (confirming understanding, not just marking tasks complete). Most companies do the first two well and skip the rest.
When should a company formalize its onboarding process?
Around 50 employees. Below that, a founder or manager can often train each hire personally. Once a company passes 50, no single person can onboard everyone, knowledge lives in too many heads, and "shadow someone for a week" produces a different version of the job every time. That's the point to document the process and make it repeatable.
How long should onboarding take for a new hire?
Plan for the first 90 days, not the first day. Day one covers logistics and access; the first week covers the team, tools, and the shape of the role; the first 30 to 90 days is where a new hire actually becomes competent at the work.
Do I need onboarding software for a 50 to 100 person company?
Not necessarily, but it helps once spreadsheets and tribal knowledge stop keeping up. For a documented, repeatable, trackable process at this size, a tool like Trainual lets you write down how each role works, build role-based onboarding paths, and see who has completed what.
