Two terms get used interchangeably in sales decks: robotic process automation (RPA) and AI automation. They are not the same thing, they cost different amounts to run, and choosing the wrong one first is a common way South African businesses burn an automation budget without much to show for it.
What RPA actually does
RPA is a script that imitates a person clicking through software. It follows fixed rules: open this spreadsheet, copy that column, paste it into that system, send this email. It is excellent when the process is stable, the inputs look the same every time, and the volume is high enough to justify the setup.
It breaks the moment the process changes. If a supplier redesigns an invoice layout or a portal moves a button, the robot keeps clicking where the button used to be. Someone has to notice, and someone has to fix the script.
What AI automation adds
AI automation handles the parts of a process where the input varies: reading an email and deciding what it is about, extracting figures from documents that do not share a layout, drafting a first response for a person to approve, or classifying incoming requests before routing them.
The trade-off is that AI output needs supervision. A well-designed AI workflow keeps a human approval step wherever a mistake would be expensive, and logs what the system did so errors can be traced. That design work is most of the job.
A practical rule of thumb
- Same input every time, high volume, stable systems: RPA or a plain integration is usually cheaper and more reliable.
- Variable input such as emails, PDFs, WhatsApp messages or handwritten forms: AI automation earns its cost.
- Judgement calls, money movement or anything customer-facing: keep a person in the loop regardless of the tool.
- A process nobody has written down: document it first. Automating chaos produces faster chaos.
The South African angle
Most local SMEs we speak to do not need either extreme. Their reality is a mix of WhatsApp orders, emailed invoices, a spreadsheet someone maintains by hand and an accounting package. The highest-return first project is usually narrow: route incoming enquiries automatically, or extract invoice data into the books with a human review step. Tools like n8n or Make.com handle the plumbing; AI handles the reading; a person handles the exceptions.
Start with the process that costs the most hours per week and has the clearest definition of done. Automate that one properly before buying a platform.
