Systems Consulting for Welsh SMEs: What to Expect and What It Costs

Short answer: A typical engagement runs audit, design, build, handover across three to six weeks. Costs range from low four figures for a single automated process to mid five figures for a full rebuild with data migration. Welsh SMEs may also be able to access business support through Business Wales and, in some cases, funding towards digital adoption — worth checking before you commission.

The four phases

Phase 1 — Audit (week one). Mapping how the operation actually runs. Interviews with everyone who touches a core process, screen-shares of real work, a tool inventory and a data quality assessment. Output is a current-state map and a ranked list of findings. Your time commitment: four to six hours.

Phase 2 — Design (week one to two). Process architecture before tooling. What the entities are, how they relate, what states exist, who owns each transition, where the source of truth sits. Tool selection follows from this rather than preceding it. Output is a target-state design you sign off before anything is built.

Phase 3 — Build (weeks two to five). Data cleaning and migration, database structure, automated workflows, integrations, reporting. Data work usually takes longer than automation work, which surprises people.

Phase 4 — Handover (final week). Documentation, training, and the playbook. This phase is where engagements are won or lost. A working system without documentation is a dependency.

What it costs

• Systems audit — often offered free as a scoping conversation; a full documented audit is a defined paid piece of work.
• Single process automation — low four figures. One workflow, defined process, reasonably clean data.
• Operational spine — mid four to low five figures. Enquiry to invoice, connected, documented.
• Full rebuild with migration — mid five figures. Includes cleaning and migrating historical data, which is usually the largest line.
• Ongoing platform costs — £30 to £150 a month for a small business.
• Maintenance — ten to twenty percent of build cost annually.

The honest variable: data quality. A quote given before anyone has looked at your actual records carries a large assumption.

Support available in Wales

Welsh SMEs have access to business support that's worth investigating before commissioning private work:

• Business Wales provides free advice, and its advisers can point towards relevant programmes and current funding.
• Development Bank of Wales offers finance options that can cover capital investment in systems.
• Local authority and regional programmes in Cardiff, the Capital Region and elsewhere periodically run digital adoption support.

Programmes and eligibility change frequently, so check current availability directly rather than relying on any published summary. A consultant who mentions this unprompted is generally acting in your interest.

What to prepare before you start

• A list of every tool you pay for, with cost and owner.
• Access, or a plan for granting it.
• Availability from the people who actually do the work, not only management.
• Honesty about the workarounds and personal spreadsheets. These are the most useful information in the audit.
• A clear statement of what success means to you, in measurable terms.

How to judge whether it worked

Define the measures before you start and take a baseline. Useful ones: hours spent on the target processes, error and rework rate, cycle time from enquiry to invoice, and how long it takes to answer a basic operational question. Retrospective estimates of "time saved" are unreliable in both directions.

Frequently asked questions

Does the consultant need to be based in Wales?

Not technically. Local presence helps most during discovery, and there's an accountability argument for working with someone in your business community.

What size business does this suit?

Typically five to fifty people. Below five, targeted point solutions usually beat a rebuild. Above fifty, you're into a different scale of project.

Can we do it in stages to spread cost?

Yes, and it's often better. Audit and design first, then build in phases with each phase delivering something usable.
