POS software vs Excel: what works for running a shop

Many shops in Cameroon run on a notebook, a calculator and an Excel file. That is a sensible way to start: it costs little and everyone understands it. The question is not whether Excel is good or bad, but when it stops being enough for your shop.

What Excel does well

• It is flexible. You can lay out a product list, prices and a stock count exactly the way you like.
• It is familiar. Most managers already know the basics.
• It is good for analysis. Sorting, totals and simple charts are quick.

For a single shop with a short product list, where the owner is at the counter most of the day, a well-kept spreadsheet can work.

Where Excel starts to break

Sales and stock live in different places

In most shops the sale is written in a notebook or a receipt book, and someone later updates the spreadsheet. Every day there is a gap between what was sold and what the file says is in stock. When the update is skipped on a busy day, the gap grows.

The same data is typed twice

Every number typed twice is a chance for a mistake: a wrong quantity, a price from last month, a product counted under the wrong name. In a spreadsheet, nothing stops these errors.

No record of who did what

A spreadsheet rarely shows who changed a quantity or a price, and when. If a figure is wrong, it is hard to find out why.

One file, one person

Spreadsheets do not handle several people well. If two cashiers or two branches each keep a copy, you soon have several versions of the truth.

Cash checks are manual

Comparing the cash in the till with the day's sales means adding up receipts by hand, separately for cash and mobile money. That is slow, so it often waits until the end of the week, when differences are much harder to explain.

Branches multiply every problem

With a second shop, you need either one file shared between places, which rarely stays up to date, or one file per shop, which you must combine yourself to see the whole business.

Signs you have outgrown your spreadsheet

• You no longer trust the stock figures in the file.
• Updating it takes someone an hour or more every day.
• You find out a product is finished when a customer asks for it.
• The cash at closing often does not match, and you cannot say why.
• You have more than one shop, or more than one person selling.
• You cannot quickly answer "what were my top products last month?"

If two or more of these sound familiar, a POS system will likely save time and reduce mistakes.

What changes with POS software

• The sale updates the stock. Each sale is recorded once, at the counter, and the stock figure follows.
• Every action has a name. Sales, voids and shifts are tied to the person who made them.
• Cash is checked every shift. The system works out the cash expected in the till, so differences show up the same day.
• Branches share one picture. Sales and stock for every shop are in one place.
• Reports are ready. Top products, sales by payment method and margin do not need to be built by hand.

Moving from Excel to a POS system

1. Clean your product list first. Remove duplicates, fix names and check prices. Your spreadsheet is a good starting point.
2. Count your stock on the day you start, so the system begins with real figures.
3. Train the cashiers before the first busy day.
4. Start with one shop if you have several, then add the others.

You may still use Excel for some analysis. Ask any vendor what you can take out of their system, and in what format, before you decide.

Conclusion

Excel is a good start, and for a very small shop it may be enough. When the stock figures stop being trustworthy, the cash rarely balances or a second person or shop joins, the time spent keeping the file up to date usually costs more than a system built for the job.
