Choosing and setting up your shop's POS and management software

The costliest mistake is starting from a salesperson's demo rather than from your own needs. Before you look at a single price, write down what the tool actually has to do in your shop, because software built for hospitality or a supermarket can be a poor fit for a shop with live animals, food with expiry dates and services such as grooming. The requirements list is your defence against the impulse sale.

• Stock management with barcodes, expiry dates and batches, essential for food and perishable products.
• A customer record linkable to purchases, for loyalty schemes and pre orders.
• Selling services as well as products, for example grooming or delivery, with separate price lists.
• Issuing tax documents compliant with your country, checked with your accountant.
• Readable sales and margin reports, telling you what earns and what sits still on the shelves.
• Data export in an open format, so you are not held prisoner if you ever change software.

With the requirements list in hand, the comparison stops being about how much you like the salesperson and becomes a table. The list price is only part of the real cost: support, training, updates and how easily you can leave all count. Cheap software that leaves you alone with a problem can cost more than one that costs more but answers when you call.

Management software is worth only as much as the data it holds: start with messy records and every report it produces will be unreliable and the mess will grow over time. It is worth spending a few days setting up the structure well at the start, because fixing it later, with thousands of rows already entered, costs ten times as much. These steps are done once and hold for years.

1. 1

   Define categories before entering products

   Decide a coherent category tree, for example food, accessories, hygiene, services, and assign each product to a single category. A well thought out tree makes all your future reports readable.

2. 2

   Use the suppliers' barcodes where they exist

   Importing standard barcodes avoids inventing your own and speeds up the till. Create internal codes only for loose items or those without a barcode, with a clear and consistent rule.

3. 3

   Enter purchase and sale prices together

   Recording both lets the system calculate the margin on every sale. Without the purchase price the margin reports are blind and you do not really know what earns you money.

4. 4

   Set minimum stock and expiry dates on food

   Turn on reorder alerts and expiry management from the start, so the stock tells you itself what is missing and what is about to expire, rather than discovering it on the shelf.

5. 5

   Link the customer record to the loyalty scheme

   If you plan a points scheme or pre orders, set up the link between customer and purchases right away. Adding it later means losing the history of customers already registered without the link.

6. 6

   Do an opening stocktake and verify it

   Before going live, count the real stock and load it into the system. Starting with stock aligned to reality is the only way for it to stay reliable in the following months.

The till is not only a management tool, it is also where the tax documents are created, and the rules change from country to country. In several European states a certified electronic register or a system that issues and transmits sales data compliantly is required. This part is not to be improvised or copied from the shop next door: it should be checked with an accountant, who knows your specific situation.

• Check with your accountant whether your country requires an electronic register or e receipts and to what specifications.
• Make sure the software is certified or compatible with local regulations before buying it, not after.
• Confirm it handles the different tax rates correctly, because food, accessories and some services can have different treatments.
• Clarify how and for how long sales data must be kept, a duty that falls on you even if the software is a third party's.
• Define staff permissions at the till, separating who can process returns, discounts and closures from who can only sell.

The best software becomes useless if whoever is at the till cannot use it or uses it differently each time. Training and a few shared rules are worth as much as the initial choice, because data entered badly by one person poisons everyone's reports. A system kept healthy with simple habits stays reliable and grows with the shop.

1. Train all staff the same way, with a written procedure for delicate operations such as returns, discounts and closing the till.
2. Decide who keeps the records up to date, so new products enter with correct category, prices and barcode.
3. Make regular backups and check they can really be restored, because a backup never tested is not a backup.
4. Periodically check that the system's stock matches the real one, to catch discrepancies early.
5. Review the sales and margin reports now and then, because a tool is there to help you decide, not just to ring up sales.

Management software is not a cost to minimise, it is a decision tool: it is worth as much as the questions it can answer about your shop.
