What Growing Tech Businesses Must Understand Before They Hire
For most IT and web design companies, growth eventually leads to one decision:
“We need to hire.”
Maybe you’re overwhelmed with client work.
Maybe delivery times are stretching.
Maybe you want to scale beyond yourself.
Hiring feels like progress.
And often — it is.
But here’s the part many IT directors underestimate:
The salary is not the true cost.
And hiring without financial visibility is one of the fastest ways to create cashflow pressure in a growing tech business.
Let’s break this down properly.
The Obvious Cost: Salary
Let’s say you’re hiring a developer at £45,000 per year.
That’s the headline number.
But it’s only the starting point.
The Hidden Employer Costs
When you employ staff, the company also pays:
1️⃣ Employer’s National Insurance
Currently 13.8% on earnings above the secondary threshold.
On a £45k salary, that’s several thousand pounds extra per year.
2️⃣ Employer Pension Contributions
Under auto-enrolment rules, you must contribute at least 3% of qualifying earnings.
That’s additional cost — even if the employee contributes too.
3️⃣ Holiday Pay
28 days per year (including bank holidays) for full-time employees.
You’re paying for time not worked.
4️⃣ Sick Pay & Leave
Statutory sick pay.
Maternity/paternity leave.
Potential absence cover.
These are part of employment risk.
5️⃣ Equipment & Software
For IT companies, this can be substantial:
• Laptop or workstation
• Development tools
• Software licences
• Hosting environments
• Security tools
• CRM access
• Cloud storage
Subscriptions multiply with headcount.
6️⃣ Insurance & Overheads
• Employers’ liability insurance
• Professional indemnity
• Office space (if applicable)
• Utilities
• Remote setup costs
The Real Cost
That £45,000 developer may realistically cost:
£55,000 – £60,000+ annually.
And that’s before considering management time, onboarding inefficiency, and training.
Hiring is not just a salary commitment.
It’s a structural commitment.
Why IT Companies Feel the Pressure
IT businesses often grow through:
• Large projects
• Short-term workload spikes
• New client wins
But project work fluctuates.
A strong quarter doesn’t guarantee a strong year.
If you hire based on one busy period, you risk:
• Fixed cost pressure
• Reduced flexibility
• Cashflow strain
• Stress during slower months
In tech, volatility is normal.
Employment costs are fixed.
That mismatch is where pressure builds.
The Contractor vs Employee Question
Many IT businesses start with contractors.
It feels flexible.
But contractors can:
• Be more expensive hourly
• Create IR35 risk if structured incorrectly
• Lack long-term loyalty
Employees provide:
• Stability
• Team development
• Culture
• Long-term capability
But they increase fixed overhead.
The right answer depends on:
• Cash reserves
• Forecast workload
• Margin strength
• Risk appetite
And that requires visibility.
The Tax Impact of Hiring
When you employ staff, you increase:
• PAYE obligations
• Employer National Insurance
• Pension contributions
• Payroll administration
This affects:
• Monthly cashflow
• Quarterly VAT (if costs change reclaim)
• Corporation Tax (as payroll reduces profit)
Hiring reduces profit — which reduces Corporation Tax.
But it also reduces cash.
That distinction matters.
The Cashflow Timing Problem
Here’s a common scenario:
An IT consultancy wins a £90k project.
They hire a developer to deliver it.
The client pays in stages over 4 months.
But payroll is monthly.
If payments are delayed?
Cashflow tightens quickly.
Revenue timing and payroll timing rarely match perfectly.
Without forecasting, this becomes uncomfortable fast.
What Should Happen Before Hiring?
Before employing someone, you should know:
✔ Current gross margin
✔ Projected profit for the year
✔ Corporation Tax forecast
✔ Cash reserves
✔ Debtor position
✔ Upcoming VAT payments
✔ Best-case and slow-case scenarios
If those numbers aren’t clear, hiring becomes guesswork.
And guesswork increases risk.
The Emotional Pressure
Hiring often feels urgent.
Clients are waiting.
Deadlines are tight.
You’re exhausted.
But urgency can cloud financial judgement.
The strongest IT companies hire strategically.
Not reactively.
A Better Approach
Instead of asking:
“Can we afford £45k?”
Ask:
• Can we afford £60k total cost?
• Can we sustain that in a quiet quarter?
• What happens if a major client leaves?
• How does this affect dividends?
• How does this affect tax reserves?
Hiring should strengthen the business.
Not stretch it.
What We Do With IT Clients
When our IT and web design clients are considering hiring, we:
✔ Review current profitability
✔ Forecast cashflow impact
✔ Model salary + employer costs
✔ Assess Corporation Tax changes
✔ Review VAT position
✔ Discuss contractor vs employee options
✔ Ensure reserves are sufficient
Because growth through hiring must be funded by structure.
Not optimism.
When Hiring Is a Strong Move
Hiring works well when:
• Margin is strong and consistent
• Cash reserves are healthy
• Tax has been provisioned
• Pipeline visibility is clear
• Management capacity exists
In those conditions, employment becomes an accelerator.
Not a risk.
Final Thought
For IT companies, people are the product.
Hiring is often necessary for growth.
But the true cost goes far beyond wages.
The most successful tech businesses don’t just ask:
“Do we need someone?”
They ask:
“Does the structure support this decision?”
If you’re considering hiring — or recently have — and would like to understand the true financial impact on your business:
👉 Book a clarity call.
Because growth through people is powerful.
But only when the numbers support it.
