Short answer: Choose a consultant who maps your processes before recommending tools, works on the stack you already have, documents everything so you're not dependent on them, and can explain what they won't automate. Be wary of anyone who leads with a tool, quotes without discovery, or won't hand over documentation. Expect discovery to be a defined, paid piece of work.
What a systems consultant actually does
The useful ones do four things in sequence: map how your operation currently runs, design the process architecture, build the connected system on suitable tools, and hand over documentation your team can run from.
What they should not do is arrive with a preferred platform and reshape your business around it. Tool-first consultants exist in numbers, often because they hold a partner relationship with the vendor. That's not automatically disqualifying, but you should know about it.
The questions worth asking
- "What's your process before you recommend anything?" Look for discovery and mapping. If the answer moves quickly to tools, that's the whole answer.
- "What would you not automate in a business like mine?" A good consultant has firm opinions here. Someone who says everything can be automated is selling.
- "What do I get at handover?" Should include process documentation, system documentation, and training. If the answer is "a working system", you're buying a dependency.
- "Who owns the build?" Your accounts, your data, your ability to modify it. No lock-in.
- "What happens when something breaks in six months?" There should be a clear answer, whether that's a maintenance arrangement or documentation good enough for you to fix it.
- "Can I speak to a client eighteen months post-handover?" Recent references show enthusiasm; older ones show whether the system survived.
Red flags
- A quote before discovery. Nobody can scope an operations rebuild from a thirty-minute call. A fixed price offered that early is either padded or about to be revised.
- A single-tool answer to every problem.
- Reluctance to document. Undocumented systems produce recurring revenue for the builder.
- No interest in your data quality. Anyone proposing to automate without examining the data hasn't done this before.
- Vague deliverables. "Ongoing optimisation" is not a deliverable.
What engagements typically cost
In the South Wales market, roughly:
- Discovery and audit — a defined piece of work, often offered free or at low cost as a scoping exercise, with a full audit priced separately.
- Single-process automation — low four figures.
- Operational spine, enquiry through to invoice, documented — mid four to low five figures.
- Full rebuild with data migration — mid five figures.
The largest variable isn't the automation complexity — it's the state of your existing data. Ask specifically how the consultant prices that risk, because a quote that assumes clean data will be revised.
Local versus remote
Most of this work is done remotely, and geography matters less than it did. Where local presence genuinely helps is the discovery phase: sitting with your team while they work reveals things video calls don't. A reasonable pattern for Cardiff and South Wales businesses is on-site discovery, remote build, on-site handover.
The stronger argument for local is accountability. A consultant twenty minutes away who might run into you at a Cardiff business event behaves differently from one you'll never meet.
Frequently asked questions
Do I need someone who knows my industry?
Less than you'd think. Operational patterns are consistent across service businesses. Industry knowledge helps with terminology and regulatory context; it doesn't determine whether the system works.
How long should an engagement take?
Three to six weeks from audit to live system for a small business. Materially longer usually indicates scope creep or a data problem that wasn't surfaced early.
Should I hire in-house instead?
Below about thirty people, rarely — the work is project-shaped rather than continuous. Revisit once you have enough ongoing systems work to fill a role.
