Outsourcing decisions in small businesses are almost never made as decisions. They happen when a founder reaches the end of a difficult month, concludes they cannot keep doing the bookkeeping at eleven at night, and hires the first bookkeeper who answers the phone. That is sometimes the right outcome, arrived at by the wrong route, which means nobody knows whether it worked.
Here is the uncomfortable truth that most content on outsourcing soft-pedals: the question is not what you dislike doing. It is what a competent outside supplier can do to an acceptable standard without your continued involvement. Those are different lists, and confusing them is why so many outsourcing arrangements produce a supplier, an invoice and no reduction in the founder’s workload at all.
This piece covers what genuinely outsources well, what does not, the real cost comparison against hiring, the employment status risk that catches SMEs, and how to make the decision properly.
The test that actually works
Not “can someone else do this”. Almost anything can be done by someone else. The test is whether the work can be specified well enough that the output is checkable without you re-doing it.
Work that outsources well shares three characteristics. The output is defined, so both parties know what finished looks like. Quality is assessable without deep context, so you can tell good from bad in minutes rather than hours. And the work does not require judgement that only exists inside your business.
Bookkeeping meets all three. Strategic pricing decisions meet none of them.
Apply the test honestly, and the list of genuine candidates is usually shorter than founders hope and longer than they fear. The uncomfortable finding is often that the work causing the most pain is precisely the work that cannot be specified, which means the problem is not resourcing at all. It is that the method has never been written down. In that case, outsourcing produces a supplier asking you questions all day, which is worse than the original position.
What tends to outsource well
Bookkeeping and payroll. Defined outputs, external standards, regulatory deadlines that create their own discipline. Payroll in particular has automatic penalties for lateness, which makes a supplier who never forgets worth real money.
Specialist compliance work. Tax returns, R&D claims, data protection reviews. Infrequent, technical, and expensive to get wrong.
Defined technical delivery. Website builds, integrations, discrete development projects with a specification.
Design and production. Where the brief can be written properly.
Facilities and IT support. Commoditised, competitively priced, easily benchmarked.
What tends not to
Sales, early on. Outsourcing sales before you know what works means paying someone to discover your proposition on your behalf, expensively and without transferring what they learn.
Anything requiring institutional judgement. Pricing exceptions, key client relationships, hiring decisions.
Undefined marketing. “Do our marketing” is not a brief. Agencies deliver activity against it, because activity is the only thing that can be delivered against an unspecified outcome.
Work you have never done yourself. You cannot assess quality in a discipline you do not understand at all, which means you are buying on trust and reputation. Sometimes reasonable. Never cheap.
Customer service, early. Your first hundred customers teach you what the product should be, and that learning does not survive the handover.
The cost comparison founders get wrong
The instinct is to compare a supplier’s day rate to an employee’s salary, which flatters employment considerably.
An employee costs the salary plus employer National Insurance at 15 per cent above the secondary threshold of £5,000 a year, plus minimum pension contributions of 3 per cent of qualifying earnings, plus employers’ liability insurance, plus holiday, equipment and the management time to supervise them. On top of that sits recruitment cost and the risk that the hire does not work.
A supplier costs their fee and the management time to brief and check them, which is real and routinely ignored in the comparison.
The genuine advantages of outsourcing are not usually about hourly cost. They are that you buy capability immediately rather than developing it, you buy variable rather than fixed capacity, and you can stop. Against that, an employee accumulates knowledge about your business that a supplier does not, and that accumulation compounds.
The practical rule that holds up: outsource where you need capability you do not have and cannot justify developing. Hire where you need capacity you will use continuously and where the accumulated knowledge matters.
The employment status risk
This is the part SMEs get wrong most expensively, and it applies whenever you engage an individual rather than a firm.
If someone works substantially like an employee, HMRC may treat them as one regardless of what the contract says. The assessment turns on the substance of the working relationship, not the wording, and the tests concern control over how the work is done, whether the person can send a substitute, and whether there is mutuality of obligation.
The consequences of getting it wrong are backdated income tax, National Insurance and penalties, usually assessed years later when the sums have compounded.
The warning signs are recognisable. The contractor has worked for you exclusively for two years. They have a company email address and a desk. You tell them when to work and how. They take holiday and tell you about it. None of those alone is decisive. Together they describe an employee.
The safer arrangements are the obvious ones: engaging a firm rather than an individual, specifying outcomes rather than hours, and keeping genuine substitution rights real rather than decorative. Take advice before the arrangement begins rather than after an enquiry starts, because the cost differential between those two moments is very large.
The mistakes I see most often
Outsourcing before documenting. Handing over undocumented work produces a supplier who asks you questions all day. Write the method first, even roughly, because it is also the specification you will brief against.
Buying hours instead of outcomes. An arrangement priced in days invites activity. An arrangement priced against a defined output invites delivery.
Not defining what finished looks like. The most common cause of a disappointing supplier relationship is that neither party ever agreed the standard.
Outsourcing the symptom. A founder drowning in admin outsources admin, when the actual problem is that a broken process generates the admin. The supplier now runs the broken process, more expensively.
Keeping the approval. If a supplier does the work and you still sign off every item, you have added a step and removed nothing from your calendar.
Choosing on price alone. The cheapest supplier is expensive if you rework their output, and you will not know which you have bought until three months in.
Never reviewing. Outsourcing arrangements are unusually persistent. Suppliers engaged in year two are frequently still invoicing in year five for work the business no longer needs in that form.
How to make the decision properly
- Log where your time actually goes for two weeks. Fifteen-minute blocks, no behaviour change. Almost every founder is surprised.
- Sort each activity by the specification test. Can the output be defined and the quality checked without you re-doing it? That is your candidate list, and it will not match your irritation list.
- Write the method for the top candidate before approaching anyone. Roughly is fine. It becomes the brief.
- Cost it properly on both sides. Supplier fee plus your management time, against salary plus employer National Insurance, pension, insurance, equipment and supervision.
- Start with one function, not three. Simultaneous handovers fail together, and you learn nothing about which part was the problem.
- Define the outcome, the standard and the reporting. Then delegate the authority as well as the task, or nothing leaves your calendar.
- Check the employment status of the position before engaging any individual on an ongoing basis.
- Review every arrangement annually against whether it is still the right shape.
The principle underneath all of this
Outsourcing does not create capacity. It converts your time from doing into specifying and checking, and that conversion is only worth making where the specifying is quick and the checking is easy. Where it is not, you have replaced work you understood with work you now supervise, which frequently costs more attention than the original.
The founders who outsource well are the ones who wrote down how the work is done before deciding who should do it. The writing down is the hard part, and it is also the part that makes everything afterwards straightforward.
Not sure whether the constraint is capacity, process or something further upstream? SGI has diagnosed growth constraints across more than 2,000 businesses in 47 industries since 2014, and the answer is frequently not the one founders expect. Book a conversation or read about Business Consulting.
SGI is not a tax or employment law adviser. Employment status is assessed on the facts of each arrangement. Take advice from a qualified accountant or solicitor before engaging an individual on an ongoing basis.
Frequently Asked Questions
What should a small business outsource first?
Usually bookkeeping and payroll. Both have defined outputs, external standards and deadlines that carry penalties, which means a reliable supplier removes both work and risk. They are also the functions where quality is easiest to assess without specialist knowledge.
Is outsourcing cheaper than hiring?
Not reliably on an hourly basis, and that is the wrong comparison. An employee costs salary plus employer National Insurance at 15 per cent above £5,000, minimum pension contributions, employers’ liability insurance, equipment and supervision. A supplier costs their fee plus your management time. Outsourcing wins where you need capability you cannot justify developing; hiring wins where you need continuous capacity and accumulated knowledge.
What should I never outsource?
Anything requiring judgement that only exists inside your business: pricing decisions, key client relationships, hiring. Early-stage sales and customer service are also usually mistakes, because those functions generate the learning that shapes the product.
How do I avoid an employment status problem?
Engage firms rather than individuals where practical, specify outcomes rather than hours, and keep substitution rights genuine. If a contractor works exclusively for you, on your schedule, under your direction, with your equipment, the arrangement looks like employment regardless of the contract. Take advice before it starts.
Why did my last outsourcing arrangement not save me any time?
Almost always one of two reasons. Either the work was never documented, so the supplier routes questions back to you all day. Or you delegated the task but kept the approval, which adds a step without removing one.
How do I know if a supplier is any good?
Define what finished looks like before you engage them, and agree how it will be measured. If you cannot articulate the standard, you will not be able to assess the output, and you will end up judging on responsiveness instead of quality.
