Workflow automation for mid-sized UK businesses: where to start
By Leena Gopinath, DeeAutomation · 21 July 2026 · 3 min read
The short answer
Start with one process that is repetitive, rule-based, high-volume and painful, such as invoice approvals, enquiry handling or onboarding. Map how it really works, fix obvious problems first, automate a small version, measure it for a few weeks, then move to the next process. Avoid starting with the most complicated workflow.
What workflow automation actually means
Workflow automation means software handles the routine steps of a process: moving information between systems, sending reminders, routing approvals, creating records and flagging exceptions. People stay involved where judgement is needed, but they stop acting as the glue between your email, spreadsheets and finance system.
For a business with 20 to 100 staff this is usually the sweet spot. You have enough volume that manual handling hurts, but not so much legacy complexity that change takes years. The aim is fewer handoffs, fewer chasers and fewer mistakes, not a technology showcase.
Choose the first process with four tests
Most mid-sized firms have a long list of candidates. Score each one against the same simple tests so the choice is not driven by whoever complains loudest.
- Repetitive: the same steps happen every time, with only the details changing.
- Rule-based: you could explain the decision logic to a new starter in a page or two.
- Frequent: it happens daily or weekly, so small savings compound.
- Painful: it causes delays, rework or visible frustration for staff or customers.
Good first candidates
Certain processes tend to work well as a first project because the inputs are clear and the outcome is easy to check.
- Purchase order and expense approvals that currently travel by email.
- Capturing and routing incoming enquiries into your CRM.
- New starter and new client onboarding checklists.
- Weekly management reports assembled by hand from several systems.
- Extracting data from supplier invoices, contracts or forms.
A sensible sequence for the first project
- Map the process as it really runs today, including the workarounds, by watching the people who do it.
- Remove steps that exist only out of habit. Automating a bad process just makes it faster at being bad.
- Define the exceptions: what should happen when data is missing or a decision is unusual.
- Build a small version covering the common case, with a human check on anything uncertain.
- Run it alongside the old way for a short period, then compare results.
- Agree what you will measure, such as time per item, error rates and turnaround, before you begin.
Common traps to avoid
The biggest trap is picking the most complicated workflow because it looks like the biggest prize. Start smaller, learn how your team adopts change, and build credibility internally. Another is ignoring the people who do the work today: they know where the exceptions hide and their buy-in decides whether the change sticks.
Watch for tool sprawl as well. Each automation should have a named owner, documentation and a plan for what happens when a connected system changes. If nobody owns it, it will quietly break and nobody will notice for weeks.
Working out whether you are ready
Before committing budget, it helps to have an outside view of which processes are worth automating and in what order. A short assessment looks at your current workflows, your systems and your data quality, then produces a ranked shortlist with realistic effort levels. That turns a vague ambition into a plan you can take to the board.
Frequently asked questions
How long does a first workflow automation project take?
It depends on the process and the systems involved. A well-scoped single workflow is often measured in weeks rather than months, but integrations with older systems or messy data can extend that. A scoping conversation should give you a realistic estimate.
Do we need to replace our existing systems first?
Usually not. Many automations connect the tools you already use, such as email, accounting software and a CRM. Replacement only makes sense if a system cannot be connected or is genuinely holding the business back.
Will automation put our staff out of work?
The aim is to remove repetitive handling so people can spend time on work that needs judgement and relationships. Involve the team early, explain what is changing and why, and let them help shape the exceptions.
