POS — Point of sale

Take payment simply — in store and online — and link every sale to your stock and your customers.

What is it?

A POS (point of sale) is the system that records and takes payment for your sales: till, payments, receipts. A modern one links physical and online selling, and updates stock and customer records with every transaction.

A till has two jobs that have nothing to do with each other. The first is taking payment: it must be fast, reliable and keep working when the network goes down. The second is feeding information back: every sale updates stock, customer records and reporting. The first is judged in seconds, the second in data quality.

That dual nature explains why generic tills so often disappoint. They take payment correctly and report badly — or the reverse. A POS that is useful to a company also selling online has to be designed as a data entry point as much as a payment terminal.

The most structuring technical constraint is offline mode. A till that depends on an internet connection to take payment stops at the same time as the connection, on a Saturday afternoon.

Signs you need it

  • Store stock and website stock never match.
  • You sell online an item that has already left the shop.
  • A customer known in store is a stranger online, and vice versa.
  • The day’s takings are reconstructed the next morning, by hand.
  • A connection outage stops you taking payment.

What is it for?

To sell fast and without friction, and to stop separating store and web: the same stock, the same customers, the same data. Every transaction feeds your reporting.

The immediate benefit is commercial: accurate stock lets you sell what you have, and promise what you can deliver. Sales missed because stock was wrong and cancellations because stock did not exist both cost money, and the second also costs reputation.

The underlying benefit is unifying the customer. Once an in-store sale feeds the same record as an online one, customer knowledge becomes usable — and a loyalty programme becomes possible, which it is not with two separate databases.

Not to be confused with

An e-commerce
E-commerce sells online, the POS takes payment — usually in store. Linked, they share stock and customers: that is what omnichannel means. Separate, they produce two truths about the same stock.
A card terminal
The terminal executes the card payment. The POS manages the sale as a whole: basket, discounts, receipt, stock, customer. The terminal is a component of the POS, not a substitute.
An ERP
The ERP orchestrates the back office: purchasing, stock, finance. The POS is the point of contact with the customer. The POS feeds the ERP in real time; without that link, the ERP’s stock is wrong from the first sale.

How it works

  1. 01We map your real checkout journey: store, web, mobile, events.
  2. 02We prototype a simple, fast till, fitted to your products and your discount rules.
  3. 03We handle offline mode from the start: taking payment must remain possible without a network.
  4. 04We connect it to your stock, your CRM and your dashboards, in both directions.

The mistakes that cost the most

  • Neglecting offline mode

    A till that does not work without a connection stops selling at the worst possible moment. Deferred synchronisation must be designed in, not added after the first incident.

  • Multiplying screens at the moment of payment

    Every question asked at checkout lengthens the queue. Information you can collect another way — email, loyalty — must not block the transaction.

  • Letting stock synchronise once a day

    With stock synchronised overnight, the website spends all day selling items that have already gone. Synchronisation must be continuous, or the site must display a safety margin.

  • Forgetting the stock count

    A POS plugged into a wrong theoretical stock produces wrong data faster. The physical stock count is part of the project.

What it costs, how long it takes

POS cost splits between software, hardware — terminals, printers, scanners — and connections. Hardware is the most visible item and rarely the heaviest; the connections to stock and CRM are the decisive one.

The variables that count: number of points of sale, complexity of discount and pricing rules, and how strict your real-time stock requirement is. Transaction volume changes implementation cost very little.

The usual lever is to start on one point of sale, stabilise offline operation and synchronisation, then roll out. A simultaneous rollout multiplies incidents by the number of stores.

When you don’t need it

If you only sell online, a POS has no purpose. And if you have a single store with no online selling, a well-chosen off-the-shelf till is usually enough: bespoke becomes justified when several channels must be reconciled, or when pricing rules are unusual.

With Meridian

We prototype a POS shaped to how you actually sell — connected to your stock and your CRM — rather than a generic till disconnected from the rest of your tools.

Frequently asked questions

POS — Point of sale

  • Are POS and e-commerce the same thing?

    No: e-commerce sells online, the POS takes payment, usually in store. Linked, they share stock and customers — that is omnichannel. Separate, they show two different stock figures for the same items.

  • Can a POS connect to my stock and my CRM?

    Yes, and that is the whole point: every sale updates stock and enriches the customer record, with no re-keying. That link is what distinguishes a modern POS from a cash register.

  • What happens if the internet goes down?

    A properly designed POS keeps taking payment offline and synchronises afterwards. If it does not, the till stops with the connection — that is the first thing to check on an off-the-shelf solution.

  • Can we keep our current till and just connect it?

    Sometimes, if it exposes an interface for exchange. Many older tills do not, or only through file export — which rules out real time and limits omnichannel.

  • Do we need a POS to sell at markets or trade shows?

    A mobile POS with offline mode makes full sense there: those sales feed the same stock and the same customer records as the store, instead of living in a notebook.

  • How do you reconcile store and online stock?

    By designating a single source of truth — usually the ERP or the POS — and making everything else a consumer of that data. Two systems that correct each other always diverge.

Glossary

Omnichannel
Sharing stock, customers and history across every sales channel, physical and online, so the customer experiences a single relationship.
Offline mode
A till’s ability to take payment without a connection, then synchronise once the network returns.
Click and collect
Order online, collect in store. It presupposes shared, reliable stock between the two channels.
Average basket
The average value of a transaction. Tracked by channel, it reveals where margin is actually made.
