The constraint is different at this size
In a fifty-person business, automation buys throughput. In a five-person business, everyone already does four jobs and the real cost is context switching: the enquiry that interrupts delivery work, the invoice chase that eats a morning.
So the ranking changes. Interruption removal beats efficiency.
What pays at five people
- Enquiry acknowledgement and routing — nobody has to watch an inbox
- Invoice generation and payment chasing, which is the most deferred task in every small business
- Scheduling links instead of arranging meetings by email
- Document generation from records you already hold
- Recurring reports that assemble and send themselves
Each saves perhaps twenty minutes a day. At five people that is a meaningful share of a working week, and it goes back into billable work rather than into admin.
What to leave alone
Anything needing a large integration project, anything requiring several roles and permissions, and anything where the volume is genuinely small. At this size, a five-figure integration rarely pays back before the business changes shape.
Also leave alone anything one person enjoys doing and does quickly. The return is not there.
Start with configuration, not development
Most small businesses use a fraction of the automation in software they already pay for: email rules, accounting reminders, CRM workflows, calendar scheduling, document templates.
Spend an hour in the settings of your three main tools before commissioning anything. We would rather tell you that than sell you a build.
When a build becomes worth it
When the same data is typed into two systems every day, when a specific error is costing money repeatedly, or when growth is being limited by admin rather than by demand.
At that point £5,000–£12,000 on one process is a sound investment, and it usually pays back inside a year at this size.
