Calculate the full cost, billable-hour requirement, supervision burden and cash reserve needed before your service business makes its first hire.
Short answer: Add salary, employer costs, equipment, software, recruitment, training and the contribution lost to your supervision. Divide that monthly loaded cost by contribution per billable employee hour. Hire only when a three-month weighted pipeline covers at least 125% of those recovery hours and cash can fund six months of loaded cost without relying on invoices that are not yet agreed.
Salary is only the visible part of a first hire. The employee will have leave, training, administration and gaps between projects. You will also sell or deliver fewer hours while recruiting, explaining work and checking quality.
The hire should release a real constraint. If demand is weak, the role is unclear or your delivery process lives entirely in your head, employment adds fixed cost without creating dependable capacity.
Plot the First-Hire Recovery Curve
The First-Hire Recovery Curve moves through four calculations: loaded cost, recoverable hours, pipeline coverage and cash endurance.
- Loaded cost: What to include: Pay, employer charges, benefits, equipment, recruitment and training; Decision threshold: Use an actual local payroll estimate
- Recoverable hours: What to include: Loaded cost divided by contribution per billable hour; Decision threshold: Must fit practical billable capacity
- Pipeline coverage: What to include: Confirmed plus probability-weighted suitable work; Decision threshold: At least 125% of recovery hours for three months
- Cash endurance: What to include: Cash available divided by loaded monthly cost; Decision threshold: Six months as a cautious first-hire guide
The 125% and six-month thresholds are working guides, not universal rules. A business with contracted recurring revenue may need less protection. One dependent on sporadic projects or one large customer may need more.
My position is that the first employee should follow proven excess demand, not be hired in the hope that spare capacity will force you to sell. Fixed payroll is an expensive source of motivation.
Calculate the fully loaded cost
Begin with gross salary and obtain current figures for employer payroll charges, workplace pension duties, holiday and any required benefits. Add recruitment, background checks where relevant, equipment, workspace, insurance changes, software access and training.
Separate one-off and recurring costs. Spread one-off recruitment and setup across the first 12 months for the recovery calculation, but show the actual payment dates in cash flow. A £2,400 recruitment and training bill is £200 a month for economic comparison, yet the bank may lose most of it before the employee starts.
Include expected sick time and paid leave by reducing available hours, not by adding salary twice. Employment obligations and costs vary by country, worker status and sector. Use current official information and obtain advice from qualified local payroll, employment and accounting professionals before offering a role.
Estimate billable capacity from a real week
Paid hours are not billable hours. Remove leave, public holidays, training, team meetings, administration and unavoidable gaps. Then allow for the utilisation you can actually schedule.
A 37.5-hour week does not create 150 billable hours every month. For a junior professional service role, 80 to 100 billable hours may be a more useful scenario to test, but it is only indicative. Build the figure from the work and calendar you expect.
Define the constrained output. If the employee prepares drawings that the founder must review, their capacity is limited by both drafting hours and founder review hours. Hiring does not release the founder when each new hour creates an equal hour of checking.
Use contribution, not the customer rate
Start with the price collected for an employee-delivered hour or project. Subtract subcontracted inputs, travel, project-specific software, sales commission, payment fees and other sale-driven costs. The remainder is contribution available to recover the hire.
If customers pay £70 an hour and project-specific cost is £8, contribution is £62, not £70. Divide loaded monthly cost by £62 to find recovery hours. Then add the contribution displaced by supervision.
Do not assume all new capacity sells at the current average rate. If the founder handles specialised work at £110 an hour while the employee will deliver routine work at £65, model £65. A blended historical figure can overstate recovery.
Worked example: ArcSpan CAD Drafting
ArcSpan produces technical production drawings for small furniture manufacturers. The founder is considering a junior drafter on a £28,000 salary.
- Salary: £28,000
- Indicative employer payroll and pension costs: £4,200
- Equipment and software: £3,600
- Recruitment and initial training: £2,400
- Loaded first-year cost: £38,200
The payroll figure is illustrative. ArcSpan must replace it with a current local calculation. Loaded monthly cost is £38,200 ÷ 12 = £3,183.33.
Junior work sells for £62 an hour and carries £6 an hour of project-specific cost, leaving £56 contribution. The employee has practical capacity for 90 billable hours a month. Before supervision, recovery requires £3,183.33 ÷ £56 = 56.85, rounded to 57 billable hours.
The founder expects ten review hours a month. Those hours could earn £70 contribution each, creating £700 of displaced contribution. Adjusted monthly recovery is £3,883.33. At £56 an hour, ArcSpan needs 69.35, rounded to 70 employee billable hours. That is 77.8% of the employee’s 90-hour capacity.
Pipeline protection at 125% requires 70 × 1.25 = 87.5, rounded to 88 weighted billable hours for each of the next three months. This almost fills practical capacity. ArcSpan should not hire until it reduces review time, raises contribution or secures a highly predictable workload.
Six months of loaded cost before displaced founder time is 6 × £3,183.33 = £19,099.98, rounded to £19,100. The reserve is not a claim that the employee will produce nothing. It prevents one slow-paying customer from putting wages at risk.
Weight the pipeline rather than counting enquiries
Separate signed work, verbally agreed work, proposals with a decision date and unqualified interest. Assign conversion probabilities from your own comparable history. If you have no history, use a cautious range and do not treat an enquiry as revenue.
Multiply likely billable hours by the relevant probability. Forty signed hours count as 40. Forty proposal hours at a demonstrated 50% conversion rate count as 20. A friendly conversation with no scope should count as zero.
Check customer concentration. Three months of work from one client is less secure than similar coverage from four, especially when cancellation terms are weak. Also map invoice dates. Pipeline can cover the recovery curve while cash still arrives after payroll.
Compare hiring with narrower alternatives
Before creating a permanent role, test whether you can remove the constraint by raising price, stopping the lowest-contribution work, improving scope, using a time-limited contractor or adding part-time hours. Compare on like-for-like quality, management and legal terms.
Do not misclassify an employee as self-employed to avoid obligations. Status depends on the real relationship, not the contract label, and rules vary by jurisdiction. Take qualified local advice.
A contractor can be more expensive per hour but safer for irregular demand. Employment can be stronger when work is repeatable, supervision is predictable and you need capacity every week. The decision is about total economics and control, not the headline hourly rate.

Make the decision over four weeks
This week, obtain a current loaded-cost estimate and record founder supervision during a trial delivery process. Next week, calculate billable capacity and contribution using three price and utilisation cases. During weeks three and four, maintain a weighted 90-day pipeline by customer and start date.
Hire only if the expected case covers 125% of recovery hours, the weak case does not threaten wages, and six months of loaded cost is available or contractually covered. If one test fails, change the role, price, hours or start date and recalculate before making an offer.
Frequently asked questions
Should I include my own supervision time in the cost?
Yes. Value the hours at the contribution you would otherwise earn or the cost of replacing the work you postpone. Also record supervision that happens outside normal hours because it still affects viability. The burden should fall as competence and documentation improve, so model month one and month six separately. Do not assume it reaches zero. Management, quality review and development remain real work. If the hire is meant to free you but consumes nearly the same hours, redesign the role before committing.
How much cash should I have before hiring?
Six months of loaded cost is a cautious starting guide for a first hire with project-based demand. Include payroll, employer costs, software, equipment and unavoidable notice or termination obligations. A business with signed recurring contracts and advance payment may need less. One with seasonal demand, long payment terms or customer concentration may need more. Keep the cash separate from tax and customer money needed for delivery. Treat it as ring-fenced cash. Employment and insolvency obligations vary, so confirm the exposure with qualified local advisers.
Is part-time safer than full-time?
It can reduce fixed cost and fit a workload that occurs on specific days, but only if the role and employee can work effectively within those hours. Recruitment, equipment and management costs do not always halve. Customer response may also require cover outside the schedule. Calculate loaded cost and practical billable capacity for the actual arrangement. Part-time employment still carries legal obligations that vary by jurisdiction. It is safer only when it matches the demand pattern, not simply because the salary number is smaller.
Should I hire before I am fully booked?
Possibly, but only when the pipeline and delivery evidence show that capacity will be needed by the start date. Waiting until the founder is at 100% can damage service and leave no time to train. Aim to prove excess suitable demand while preserving a 15% to 20% operating buffer. Do not interpret personal busyness as employee demand until you remove low-value administration and poorly priced jobs. The hire should absorb repeatable work customers will pay for, not every task the founder dislikes.
Can I use revenue to decide whether I can afford an employee?
No. Use contribution from the work the employee can deliver. Revenue does not account for project materials, travel, commission or other sale-driven cost. A £5,000 project with £3,500 of direct cost contributes less than a £3,000 project with £500 of direct cost. Divide loaded employee cost by contribution per billable unit, then test capacity and cash timing. Revenue can describe scale, but it does not pay wages until the associated costs and collection delay are recognised. That distinction matters.
What if the employee brings in their own clients?
Count that value only when client ownership, pricing, capacity and likely retention are clear. A candidate’s relationships are not contracted revenue. Separate delivery hours from selling hours and include any commission or reduced billable capacity. Agree lawful terms on customer information and post-employment restrictions with qualified local advice. The role may justify a different recovery curve if business development is explicit, but do not hide a sales assumption inside a delivery hire. Track the acquired contribution separately for the first six months.
When does a hire become affordable after a price increase?
When the new price is being accepted by suitable customers and collected, not when it appears on the price list. Quote it across at least ten comparable opportunities, measure conversion and contribution, then update the recovery calculation. A higher rate may reduce billable demand while still improving total contribution. Use the expected mix, not the best quote. If the hire only works at a price no customer has paid, you have a pricing test to complete before an employment decision.
