What Growing Tech Businesses Must Understand Before They Hire
For most IT, SaaS, and web design companies, growth eventually leads to the same decision:
“We need to hire.”
Maybe delivery is stretched.
Maybe client demand is increasing.
Maybe you’re simply at capacity.
Hiring feels like progress.
And often, it is.
But here’s the part many IT directors underestimate:
The salary is not the true cost of employment.
And hiring without financial visibility is one of the fastest ways to create cashflow pressure in a growing tech business.
The Obvious Cost: Salary
Let’s say you hire a developer at £45,000 per year.
That’s the headline figure.
Clear. Simple. Predictable.
But it is only the starting point.
Because employment carries multiple additional cost layers that are often not included in initial planning.
The Hidden Employer Costs
1️⃣ Employer’s National Insurance
Employer’s National Insurance is currently charged at 13.8% above the secondary threshold.
On a £45,000 salary, this adds several thousand pounds per year in additional cost.
It is automatic, unavoidable, and must be funded through payroll cashflow.
2️⃣ Employer Pension Contributions
Under UK auto-enrolment rules, employers must contribute a minimum percentage of qualifying earnings.
Typically at least 3%, though many businesses contribute more to remain competitive.
This is a recurring cost that increases with every additional employee.
3️⃣ Holiday Pay
Full-time employees are entitled to approximately 28 days’ paid leave per year (including bank holidays).
This means:
You are paying salary for time not worked.
In service-based IT businesses, this must be factored into utilisation and pricing assumptions.
4️⃣ Sick Pay and Absence
Employment also includes unavoidable cost variability such as:
- Statutory Sick Pay
- Maternity/paternity leave
- Short-term absence cover
- Reduced capacity during leave periods
These costs are not always predictable, but they are always real.
5️⃣ Equipment and Software Costs
In IT businesses, this category is often significant.
Additional employees may require:
- Laptops or development machines
- Software licences (IDE tools, design tools, SaaS subscriptions)
- Cloud infrastructure access
- Hosting and deployment environments
- Security tools and VPNs
- CRM and project management systems
These costs scale directly with headcount.
6️⃣ Insurance and Overheads
Depending on your setup, additional employees may increase:
- Employers’ liability insurance
- Professional indemnity exposure
- Office or coworking costs
- Utilities and infrastructure
- Remote working setup costs
Even lean, remote-first businesses still carry overhead increases per hire.
The Real Cost of Employment
When all factors are combined, a £45,000 developer can realistically cost:
£55,000–£60,000+ per year
Before considering:
- Onboarding inefficiencies
- Management time
- Reduced productivity during ramp-up
- Training investment
Hiring is not just a salary decision.
It is a structural cost decision.
Why IT Businesses Feel the Pressure
IT companies typically grow in uneven cycles:
- Large project wins
- Short-term delivery spikes
- Retainer fluctuations
- Pipeline variability
Revenue is rarely perfectly stable.
But employment costs are.
That mismatch creates financial pressure.
Hiring based on a strong month or project can create long-term fixed cost strain during quieter periods.
The Contractor vs Employee Decision
Many IT businesses initially rely on contractors.
This offers flexibility but comes with trade-offs:
Contractors:
- Higher hourly cost
- Potential IR35 exposure
- Limited long-term retention
- Reduced cultural integration
Employees:
- More predictable cost structure
- Stronger team continuity
- Better long-term capability building
- Greater commitment to the business
But employees introduce fixed cost pressure.
The correct choice depends on:
- Cash reserves
- Forecast workload
- Margin stability
- Risk tolerance
And that requires financial visibility.
The Tax Impact of Hiring
Employing staff changes your tax position.
It affects:
- PAYE obligations
- Employer National Insurance
- Pension contributions
- Corporation Tax (through reduced profit)
Lower profit can reduce Corporation Tax — but it also reduces available cash.
That distinction is critical.
The Cashflow Timing Problem
A common scenario in IT businesses:
- A £90,000 project is secured
- A developer is hired to deliver it
- Client payments arrive in stages
- Payroll is fixed monthly
If client payments delay or pipeline slows, cashflow tightens quickly.
This is not a profitability issue.
It is a timing issue.
Without forecasting, it becomes a pressure point.
What Should Be Known Before Hiring
Before employing staff, directors should have clarity on:
✔ Current gross margin
✔ Forecast annual profit
✔ Corporation Tax exposure
✔ Cash reserves
✔ Debtor position
✔ VAT liabilities
✔ Best-case and worst-case scenarios
If these are unclear, hiring becomes assumption-based rather than structured.
The Emotional Side of Hiring
Hiring often feels urgent.
Deadlines are tight.
Clients are waiting.
Capacity is stretched.
But urgency can distort financial judgement.
The strongest IT businesses separate:
- Operational pressure
- Financial capacity
They do not hire reactively.
They hire with structure.
A Better Way to Think About Hiring
Instead of asking:
“Can we afford £45,000?”
Ask:
- Can we afford £60,000 total employment cost?
- Can we sustain this during a slow quarter?
- What if a key client leaves?
- How does this affect tax reserves?
- How does this affect dividends?
Hiring should increase stability — not reduce it.
What We Do With IT Clients
At Hammond & Co, when IT and web design clients are considering hiring, we:
✔ Review current profitability
✔ Model full employment cost
✔ Forecast cashflow impact
✔ Assess Corporation Tax implications
✔ Review VAT position
✔ Compare contractor vs employee options
✔ Stress-test slow and peak scenarios
Because hiring decisions should be backed by data — not optimism.
When Hiring Is the Right Move
Hiring is usually a strong decision when:
- Margins are consistent
- Cash reserves are healthy
- Tax is fully provisioned
- Pipeline is visible
- Utilisation is stable
In those conditions, hiring becomes an accelerator of growth.
Not a financial risk.
Final Thought
In IT businesses, people are the product.
Hiring is often necessary for growth.
But the true cost of employment goes far beyond salary.
The most successful tech companies don’t just ask:
“Do we need someone?”
They ask:
“Does the structure support this decision?”
Because growth through people is powerful.
But only when the numbers support it.
