Automating the Boring Tasks in Your Business

My day job has been in finance and project accounting for many years, and much of that work is the same steps every month: download reports, clean them, match numbers, build the same summary, send it to the same people. Automating those steps, first with Excel macros and later with small scripts, gave me back hours every month and made the numbers more reliable.

The same approach works for any small business. Here is how to find the tasks worth automating and how to do it without creating something nobody can maintain.

Step 1: Find the repeat work

For two weeks, note down every task you do more than once. Next to each one, write how long it takes and how often it happens. You are looking for tasks that are frequent, follow the same steps each time, and involve copying data from one place to another.

Good candidates usually look like: making the same report every week or month, re-typing data from one system into another, matching two lists such as bank statements and invoices, and sending the same reminder emails.

Step 2: Do the maths

Multiply the time per task by how often it happens in a year. A 30-minute report done every week is 26 hours a year. If automating it takes a day and saves most of that time, it pays back within months. A task done twice a year usually is not worth automating, however annoying it is.

Also count the cost of mistakes. A manual reconciliation that sometimes misses an entry can cost far more than the time it takes.

Step 3: Use the simplest tool that works

Start with what you already have. Most business data already lives in Excel or Google Sheets, and formulas, Power Query or a short macro can handle a surprising amount. A good tool is one the next person in your team can understand.

• Excel formulas and Power Query: cleaning, combining and summarising data
• VBA macros or Apps Script: repeating fixed steps, building reports, sending emails
• Small Python scripts: larger files, multiple sources or tasks Excel struggles with
• A custom app: only when many people need the same workflow every day

Step 4: Automate one step at a time

Do not try to automate a whole process in one go. Pick the most painful step, automate it, and run it alongside the manual way for a cycle or two to check the results match. When you trust it, move to the next step.

In my monthly reporting, the first win was simply standardising the raw data: same column names, same date format, same project codes. Once the input was predictable, the summary and the checks were easy to automate.

Step 5: Build in checks

An automation that runs silently with wrong data is worse than doing it by hand. Add simple checks: totals that must match, row counts that should not drop suddenly, and a clear warning when something looks off. In finance work, a control total at the end of every report is non-negotiable.

Step 6: Write down how it works

Keep a short note with every automation: what it does, where the inputs come from, how to run it and what to do if it fails. Automations outlive the person who built them, and an undocumented macro becomes a risk the day its author goes on leave.

Where to start this week

Pick one weekly report or data entry task, time it, and see whether formulas or a short macro could remove most of the manual steps.
