Growing pains are inevitable for any service based business. The good news is there are tried and tested formulas for knowing the right time to act, so growth stays sustainable from both a workflow and a cash flow perspective.
This comes down to one practical question: when can you actually afford to hire your next employee? Getting the timing right is the difference between building an unprofitable monster and building a business that generates cash as it grows.
When is the right time to hire?
Most service based business owners hire on gut feel. The decision usually comes down to how busy the team is, the size of the current backlog, or whether people are starting to burn out.
The trouble with gut feel is that it is inconsistent.
On an optimistic day, it is easy to feel like opportunity is everywhere and start hiring ahead of demand, which leaves new staff with little to do and quietly erodes margin.
On a cautious day, the instinct flips to penny pinching, which puts pressure on the existing team and can push good people towards burnout, and eventually, the door.
A more reliable approach is a systematic one. This is what hiring economics actually means.
The costs of hiring
New employees need time to become productive. They are not switched on from day one, they need time to ramp up into the role. That ramp up time, along with the resources and energy it takes to get a new hire up to speed, puts real pressure on the business in the short term.
The effort your existing team spends onboarding a new hire is effort not spent generating revenue. If the timing is wrong, the cost of a new hire can outweigh the revenue it generates, leading to little or no new profit, and in some cases, an outright loss. This is exactly the kind of direct cost that determines your agency’s gross profit margin.
It matters to factor in enough revenue to cover not just the new hire’s salary, but the indirect costs of training and ramp up as well.
Finding the magic number
So how much revenue or cash is actually enough to justify a new hire?
The rule of thumb is to have at least two times the new hire’s monthly salary already committed in the sales pipeline. If a new hire costs $10,000 a month in salary and super, that means at least $20,000 a month of committed sales, ideally locked in before the employment contract is signed.
Without that buffer, the cost of the new hire can erode the profit generated from the new sales it was meant to support. If that cycle repeats across multiple hires, a business can end up growing revenue and headcount without actually growing profit.
A business hiring purely on gut feel tends to add a new team member every time sales grow, without checking whether the timing actually supports profitability. A systematic approach follows the same pattern of hiring as sales grow, but times each hire so that the profit from that growth is actually retained, rather than immediately absorbed by the cost of the new hire.
This can understandably feel like a chicken and egg problem. Committing to work without the right person in place is risky, and hiring the right person without confirmed work is equally risky.
One practical way through it is to run the early stages of recruitment, posting the role and reviewing applications, in parallel with locking in the revenue, then move to interviews once that revenue is committed.
Whether this applies depends on whether you are adding a new service line or simply expanding an existing one, but the underlying principle holds either way.
In summary
Revenue is only half the picture. The other half is cash flow, the actual cash needed to pay your team and keep the business running day to day.
Next time you are weighing up whether you can afford to hire, come back to the two golden rules of hiring economics: two months of committed revenue, and two months of cash in the bank. Following this consistently is what separates growing profitably from growing broke.
