Retail POS

A retail POS, short for point of sale, is the system that completes a sale in a physical shop: it rings up the items, takes the payment, issues a receipt, reduces stock and records what happened. POS can mean the software, the hardware on the counter, or the moment of sale itself, and in practice people use it for all three.

The part most brands underestimate is the last one in that list. A POS is not only a till. In much of Europe it is also the device that proves to a tax authority what you sold, and that obligation is what turns a simple purchase into a compliance decision.

What does a retail POS actually do?

Cloud POS, on-premise and mobile

• Cloud POS. The software runs as a service and the data sits centrally, so several stores and the online shop can share one stock position. It needs connectivity, and any serious setup needs a plan for what happens when the connection drops.
• On-premise POS. The software runs on a machine in the shop. More resilient offline, far harder to keep in step across locations, and usually the reason two stores disagree about stock.
• Mobile POS. A tablet or phone with a card reader, used on the shop floor or at a pop-up. The format that makes short-term retail practical at all.

Most brands now run cloud POS with offline fallback, which is the sensible default. The question that actually matters is not which of the three you pick; it is whether the stock the till decrements is the same stock the website is selling.

What a POS has to prove to a tax authority

This is the part that separates selling in one country from selling in several, and it is where most expansion plans lose time.

Several European countries require the POS itself to be certified or registered, so that sales cannot be altered after the fact. The arrangements have their own names and their own rules: a technical security element in Germany, certified software in France, a registered telematic recorder in Italy, certified invoicing software with document validation codes in Portugal. Others, including the United Kingdom and the United States, impose no device requirement at all and rely on ordinary VAT registration or sales tax registration instead.

Three consequences follow, and they are worth knowing before signing a lease:

• The burden is per country, not per company. A POS setup that is compliant in Amsterdam may need certified hardware in Milan.
• It is per device and often per store. Registration usually attaches to the physical till, so another location means another registration.
• Lead time is the real cost. Certified hardware has to be procured, configured and registered, and in the stricter markets that is the longest item on the plan.

Rules change and the detail differs by country, so confirm the current position for each market rather than assuming one setup travels.

What goes wrong with retail POS?

• Stock that lives in two places. The store sells the last unit, the website sells it again an hour later, and somebody gets a cancellation.
• Tax configured once. Rates differ by country, by product category and sometimes by region. Set up on launch and never reviewed, the till quietly charges the wrong amount for months.
• Treating the receipt as a formality. In several markets its contents and its numbering are prescribed, and a non-compliant receipt is a compliance failure rather than a design choice.
• Who the money settles to. The card terminal pays whoever holds the merchant account, which is not automatically the brand whose product was sold. Worth resolving before the first trading day, not after.
• Venue wifi. At a pop-up or a fair, shared wifi fails exactly when the queue is longest. Dedicated connectivity is cheap insurance.
• No plan for returns of online orders. Customers expect to return in store, and that crosses the boundary between two systems and often two tax treatments.

FAQ

What does POS stand for in retail?
Point of sale. It refers to the moment and place a purchase is completed, and by extension to the software and hardware that complete it: the till software, the card terminal, the scanner and the receipt printer.

What is a POS system in retail?
The combination of software and hardware that rings up a sale, takes payment, issues a receipt, reduces stock and records the transaction for reporting and tax. Modern systems also connect the shop to the online store so both draw on one stock position.

What is the difference between cloud POS and on-premise POS?
Cloud POS runs as a service with data held centrally, which makes multi-store and online stock sharing straightforward but depends on connectivity. On-premise runs locally, survives an outage better and is harder to keep consistent across locations.

Does a POS need to be certified?
In some countries, yes. Several European markets require certified or registered POS devices or software so that sales records cannot be changed afterwards. The UK and the US have no such device mandate. The requirement is per market, and often per store and per device.

Can one POS cover several countries?
The software usually can. The compliance around it usually cannot, because registration, certification and tax treatment are handled country by country. Expanding across borders is a registration exercise more than a software one.

A till is easy. Being allowed to use it in a given country, with the right tax treatment, a compliant receipt and the money settling to the right party, is the slow part. eBrands acts as the legal seller in each market so a brand can open a counter without building that layer itself.
