Ecommerce Web Design & Development


We have built “one-product-only” e-commerce sites to sites with over 500,000 products

At Datadial, we are an eCommerce development agency who have built e-commerce websites that coordinate offline and online order processing, integrating with all kinds of third party systems.   We have created bespoke add-ons allowing clients to manage their entire business via their website.


But what platform to build it on?  Off the shelf, open source or bespoke?

We try to be platform agnostic, that’s to say we don’t dictate which platform you should use but we propose a solution based on your needs. Bespoke e-commerce sites are more appropriate for more complex sites with sophisticated requirements.


Shopping Cart

Shopping Cart or “off the shelf” e-commerce sites are appropriate for smaller websites which have more standardised e-commerce requirements, such as Shopify  or Woo Commerce.  Larger off the shelf tools like Magento may be feature rich but not necessarily perfect for every solution.



Most e-commerce web design software gives you the ability to easily offer your products for sale online. That’s the easy part. The trick is merchandising your product inventory so that you maximise AOV and repeat sales.

Our web design, SEO and programming teams all work on your site at the same time with one aim in mind: to maximise conversion rates.


How much does it cost?

E-commerce web design sites come in all shapes and sizes.  To give you an idea:

Small – £7,500-£15,000
Medium- £15,000-£30,000
Large- £30,000- £80,000+

Made for you

Your site is built exactly how you want it. You’ll never hear us say “that can’t be done”. We’re much more likely to say “oooh that’s a good idea let’s build it.” And we’ll continue to make suggestions and tweaks as your site grows to maximise your conversion rate.


All our e-commerce websites are PCIDSS compliant as specified by Visa, Mastercard and Amex Data protection programs.


We manage and host all websites that we develop.  Our hosting environment includes redundancy, mirroring and load balancing as standard.  No other agency offers this level of hosting as default.

Naturalmat – magento 2 & SEO- mattresses and beds


Naturalmat is the UK’s leading manufacturer of organic mattresses. Handmade in Devon, their mattresses are supplied worldwide to hotel chains and direct to consumers via their stores and their website.


Naturalmat had outgrown their old website and needed a new digital presence to help progress their next phase of growth. We identified issues with their old site such as missing ‘trust signals’, a confusing user journey and a CMS platform that was

becoming obsolete and not fit for future growth…


We moved Naturalmat over to Magento – the world’s leading ecommerce platform. By performing a detailed competitor analysis, we were able to identify the full search demand landscape and create granular, faceted navigation for an improved user journey that also allowed for greatly improved SEO performance.

Trust factors like testimonials, reviews and product USPs were brought to the fore in our design and the speed and performance of the site dramatically increased. The new Naturalmat site looks stunning and works brilliantly for users and for the client

administrating it.


Results since the launch of the new site have been amazing…

  • Overall traffic is up 24%
  • Organic traffic up 12%
  • Total revenue up 56%
  • Revenue from organic search up 85%
  • Conversion rate has increased 20%
  • Number of transaction up 48%

Design911 – bespoke e-commerce – Porsche parts
Design 911

Porsche Parts E-commerce Website

see website

Most clients now want their site built on commercially available software, preferably open source. However there are times when proprietary software can be the best option.

The design911 site is built on Datadial’s first iteration of its own e-commerce software, launched around 2004. It has had functionality upon functionality added to it and yet still the underlying software has been resilient and robust.

If it had been built on a purchased e-commerce software it’s very likely that we would have come up against limitations many years ago.  As it is we have been able to build on and expand the site without any issues as we have total control of the source code.

Over and above the all standard  e-commerce functionality  this site includes:

  • abandoned basket email functionality,
  • tyre finder,
  • fast part finder,
  • find parts via part diagrams digitised from car manuals,
  • automatic feeds for Google and Ebay,
  • integration with Orderwise stock control system
  • bulk imports
  • payment by bank transfer
  • kiosk functionality for use in garages for touchscreen
  • mobile website
  • and much more

How have we managed to work together for so long (since 1998) and still get on?

As one of our first clients we are proud that we are still working on the Design911 website after so long and still adding more and more functionality to their site.

To the credit of Design911 they are willing to try out new ideas to grow their business online.  Sometimes these work, sometimes they don’t, but as both companies view the relationship for the long term it’s an accepted principal that this will be part of the process.

We originally came together from an Advert that we had placed on Loot, free ad newspaper (pre Gumtree et al). If you remember Loot then you’re probably getting on, like us :)

TurtleMat – web based call centre software – bespoke e-commerce
Turtle Mat

Part of an e-commerce project linking Call Centre, Fulfillment House and Website.

Turtle Mat have customers who like to order online or by telephone.  There was an issue in that their telesales team had no access to online orders or customer information.  So people ringing up to enquire about an order were often given the incorrect information as the telelsales team had no access to online orders.

Turtlemat use an outsourced telesales company who are used to working with their own software, so it was a challenge to build them something that would be easily adopted and easy to use.  When we produced the final call centre software for them we were told that it was the best that they had ever used from a 3rd party provider.

Now when ever any calls to discuss an order which was placed online, or if they look up an order online which they placed by phone they get the same information. Telesales staff also now have access to all the online offers and promotions running at any one time.

The integration of the call centre software was part of an e-commerce project linking Call Centre, Fulfillment House and Website all together.


Datadial understand what we want and make it happen with ease - and always to our tight deadlines.

Vanessa Arbuthnott – made to measure curtain and upholstery ordering

Bespoke Curtain Ordering Software

This is an example of a website for which off the shelf shopping software would not be able to cope.

If you have ever ordered a pair or curtains you will know how complicated it can be.  You need to know about pattern repeats, drops, width measurements, pelmet pleats, flop overs, piping, poles, tiebacks, voiles, cushions and how to calculate it all in an instant for the online user.

As this was a redevelopment of an existing site the client had a sophisticated set of requirements not just for curtain calculations but also delivery management and accommodation of standard e-commerce products.

So we developed a bespoke e-commerce website.

The site accommodates:

  • Made to Measure Curtains, Roman and Swedish Blinds, Quilts, Cushions, Upholstered Chairs, Sofas, Wallpapers and standart products.
  • There are lots of additional options where relevant such as options for second lining fabrics, border fabrics piping, buttons etc.
  • Includes multiple payment options including phone, cheque, PayPal, credit card.
  • Sophisticated delivery management allows for split deliveries for orders containing mixed product types such as a sofa and a free sample. Dynamic Postcode calculator offers cheapest postage options.
  • Includes back end call centre order entry and CRM.   All fully updateable via bespoke CMS

Built from the ground up with SEO in mind,  this is the only fully SEO friendly curtain website in the world as far as we know!


Loom and Last – curtain ordering software – Made to measure curtains
Loom and Last

Curtain ordering software. We really had to pull ourselves together for this one!

Natural Curtain Company approached Datadial when they realised their existing site was failing and that the platform that it was built on could not sustain the complexity of their product offering, nor was it extensible enough to accommodate new products.

Instead of shoe-horning Natural Curtain’s business model into pre-existing e-commerce software as had happened on their previous site we instead built the site to their exacting requirements from the ground up.

The result is a complex and sophisticated ordering system that has minimised the amount of in house administration of online orders and virtually eliminated user errors on the site as there is now so much validation before ordering that users cannot order the wrong thing.

The site is integrated with Datadial’s email marketing software as well as Wufoo and online survey tool as well as their own bespoke order management system.

The site has also been supported by an online marketing campaign to keep the site listed for any curtain related queries.  A recent conversion rate optimisation exercise where we A/B tested homepage layouts had the effect of increasing revenue by 30%.

It is clear that our customers like the new website. I love it. So a big thank you from me and all at the ever-growing Natural Curtain Company.
