E-commerce and point of sale development: A store and a till that never disagree about stock.
An online store and a till that share the same products and the same stock, so the counter and the website never disagree. At the counter it works with the fiscal device Cyprus law requires.
Three published case studies

What that includesCOMMERCE
Stores and tills, one catalogue
- WooCommerce storefronts and custom themes
- A till at the counter that sells from the same stock as the website
- Large catalogues, and “find the part that fits my vehicle” search
- Delivery, collection and pickup-point options at checkout
- One stock figure shared between counter and website
- Payment gateways, cash on delivery and age verification

A shop that sells in a room and on a website has one catalogue, whatever the software says. Most of the work in commerce is making that true.
We build stores on WooCommerce because the business owns the software outright, and because it can be made to do things a hosted platform will not: four-level catalogues, fitment finders that never offer a dead end, collection from a courier's shop, or a product where each unit is unique and can only be sold once.
Where an off-the-shelf point of sale is fighting the store, we replace it with a terminal of our own that writes ordinary orders and moves ordinary stock, so the counter and the website stop disagreeing.
01Who it is for
A shop that sells over a counter and online and is tired of the two disagreeing, or a store whose catalogue is too deep or too unusual for a hosted platform: parts that must fit a vehicle, works that exist once, stock that needs an age check.
If this is the wrong service for you, we will say so and point you to the right one.
02What you get
- A WooCommerce store you own outright, with a theme built for how you sell
- A point of sale that writes real orders against the same catalogue and stock
- Delivery, collection and pickup-point options at checkout, and the payment methods you need
- A test copy of the live store, so changes are tried before your customers see them
- Hosting, backups and support after launch
03What we need from you
Admin access to the store and its hosting; your own business accounts with the payment provider and the courier, since those contracts stay in your name; and a list of what the current setup gets wrong, however small.
Is this what you need?
Describe the job in a few lines. If this service is the wrong fit, we will say so and point you to the right one.

inquiries@kdvassiliougroup.com01Can you work with the systems we already use?
Usually that is the job. We connect what a business already pays for — couriers, payment providers, accounting and suppliers — so that work stops being retyped between them.
