What Is RPA? — Software That Does What Humans Do on Computers, Faster

In many organisations, there are people whose job involves doing the same sequence of computer tasks over and over again. Log into a system. Copy some data. Paste it into another system. Fill in a form. Send an email. Log out. Repeat.

This is not skilled work. It is mechanical, repetitive, and error-prone when done by humans at volume. It is also exactly the kind of work that software can do faster, more accurately, and without getting tired.

Robotic Process Automation — RPA — is the technology built specifically for this.

What is RPA?

RPA uses software robots — bots — that mimic human interactions with computer systems. The bot can open applications, log in, read data from a screen, copy and paste between systems, fill in forms, click buttons, and send emails — exactly as a human would, but faster and without errors.

The key distinction is that RPA works at the user interface level. It does not need to integrate with the underlying database or API of a system. It interacts with the system the same way a human does — through the screen. This means RPA can automate tasks in legacy systems that have no API and cannot be changed.

A simple example

An accounts payable team receives invoices by email every day. Each invoice needs to be opened, key data extracted — supplier name, invoice number, amount, date — and entered into the accounting system. Then a confirmation email is sent. An RPA bot does all of this: opens the email, reads the invoice, enters the data into the accounting system, and sends the confirmation. The human reviews exceptions. The routine work is done automatically.

Where RPA is used

Banking and finance — processing loan applications, reconciling accounts, generating compliance reports. Insurance — processing claims, verifying policy details, updating customer records. Healthcare — scheduling appointments, processing medical records, billing. HR — onboarding new employees, processing leave requests, updating payroll systems. Logistics — tracking shipments, updating order status, generating delivery reports.

RPA vs API automation

API automation connects systems directly at the data level — faster, more reliable, and more scalable. RPA works at the user interface level — slower, but it works with any system a human can use, including legacy systems with no API. For modern systems with good APIs, API automation is always preferable. RPA is the right choice when the system is old, cannot be changed, and has no API.

The simple rule

If a human does it on a computer by clicking and typing in the same sequence every time — a bot can do it faster, more accurately, and without getting tired. That is RPA.
