BUILDFeatures, apps and integrations

Custom development for stores that have outgrown their platform

Your store should work the way your business does. When it doesn’t, someone on your team fills the gap by hand, retyping orders, fixing stock counts or working around a missing feature.

Web Ecommerce Pros is an ecommerce development company that closes those gaps. We extend your store, connect your business systems and build custom functionality around your requirements, so your store supports how you sell, manage products and fulfill orders.

Bring us a feature you need, an integration that creates extra work or a system that needs improving. We’ll take it from there.

  2. 2 Order information reaches the agreed system
  3. 3 Fulfillment information returns to the store

Not a real client integration. What connects, and how, is agreed for each store.

Platforms we work on

Development across the major ecommerce platforms

  • Shopify
  • BigCommerce
  • WooCommerce
  • Magento
  • Volusion
  • OpenCart
  • Shift4Shop
  • Zen Cart

Platform names and logos belong to their owners and show which platforms we work on. They are not partner credentials. We are an independent agency.

Where we can help

What does your store need to do?

Whatever cart your store runs on, we start from the job you need done. Some of these requests need custom code and some don’t, and platforms differ on what they handle natively. We work out which is which with you.

Offer more flexible product choices

Personalized items, bundles, configurable products and special ordering rules. We check what each one would take.

Support your B2B customers

Customer accounts, special pricing, quotes and ordering rules get checked against your platform and the extensions available for it.

Reduce repeated data entry

Product, customer, order and inventory details can pass between your store and your other systems, so nobody retypes them.

Improve an existing workflow

Manual workarounds, connections that keep failing and custom functionality that needs attention are all worth a look.

What we build

Custom ecommerce development

Sometimes a standard feature or app does the job. When it doesn’t, custom ecommerce development covers the gap. We begin with the business requirement and a look at your current store, then recommend whether configuration, an established extension or a custom solution fits.

Is there a feature your platform lacks, or one that’s too hard to set up yourself? Tell us what you need and we’ll say what’s realistic. We don’t promise to build anything and everything, and the options depend on your platform.

Custom store features

Functionality for products, pricing, accounts, ordering and admin work, within what your platform allows.

Apps, plugins and extensions

Purpose-built tools, or the right extensions added to what you already use.

Business workflow automation

Fewer repeated steps, through agreed rules, data connections and supported interfaces.

Store implementation

We configure and build the technical pieces for a new store or an agreed platform change. Migration detail is on our migration pages.

Existing-code improvements

We look over custom functionality, technical problems and inherited code before we define the work.

Performance and reliability

We study how the application behaves and which technical factors contribute. Fixes follow the evidence, and we don’t promise any universal score.

Hosted platforms have limits. We work inside what each platform supports, and we won’t claim backend access a platform doesn’t allow.

Connecting your business

Ecommerce integration

Your store is one part of a larger business. Our ecommerce integration services help work out how it should swap information with the systems that handle customers, products, stock and fulfillment, including custom API integrations when a suitable interface exists.

ERP and accounting

For ecommerce ERP integration, we look at which order, product, customer or financial data needs to move. The right scope differs from one ERP or accounting product to the next.

CRM and customer systems

Customer and enquiry details can flow across with agreed permissions and handling.

Inventory and product information

We settle product identifiers, who owns the data and the update rules across the systems involved.

Shipping and fulfillment

We look at how orders are handed off, plus fulfillment updates and tracking details.

Questions we settle before we build
Planning
  • Which system owns each type of information?
  • What needs to move?
  • Is the flow one-way or two-way?
  • How frequently should updates occur?
  • What happens when a transfer fails?
  • How are duplicate updates prevented?
  • Who maintains each part of the connection?

We don’t promise real-time synchronization by default, unlimited API access, compatibility with every business system, a connector where none exists, or error-free operation forever. Naming a system here is not a partnership claim.

Find your platform

Ecommerce development for your platform

Every platform has its own strengths, limits and habits. Pick yours to see how we handle development there.

Zen Cart

Customization, modules and technical improvements for existing stores, after we review the installation.

How it works

From business requirement to working functionality

We test the workflows a change touches, for example product and pricing behavior, accounts and permissions, cart and payment flow, inventory updates, order and fulfillment details, and what happens when something fails.

Why WEP

Why choose WEP as your ecommerce development company?

We’ve worked with all the major consumer and enterprise shopping cart platforms across more than 20 years in ecommerce, and that experience goes into your store.

Business requirements before code

Before we recommend custom development, we look at the problem and the options that might solve it.

Experience across platforms

We plan around the platform you really use, because stores don’t all work the same way.

The store and operations together

We think through what a feature does to your products, orders, people and connected systems.

Clear scope and communication

Your project contact keeps communication fast and clear, with agreed responsibilities and progress you can see.

Web commerce pros created a really lovely design for our website. They also changed the layout for our images and updated/resized images so that the site is overall much more attractive. We have been receiving a lot of positive feedback from customers on the ease of use and the overall look of our site. In addition, we are very grateful to Roy for coming up with a creative solution for allowing customers to easily create their own quotes, which has been very helpful to both our operations and our customers.

FAQ

Ecommerce development questions, answered

Plain answers about custom ecommerce development, integrations, cost and ownership.

Ecommerce development

Custom store features, apps, extensions, integrations and improvements to existing functionality. How much applies depends on your platform, the requirement and your current setup.

It is building or adapting something your store can’t do with its current setup or tools. That might be a custom feature, an application or a connection to another system.

Yes. We’ll look at the platform, the code, the extensions and what you need, then recommend targeted improvements.

We cover Shopify, BigCommerce, WooCommerce, Magento, Volusion, OpenCart, Shift4Shop and Zen Cart. Whether we can take on a job depends on the specific installation and requirement.

Try an app first if a well-maintained one fits. Custom work makes sense when the standard options don’t meet the requirement or force an unsuitable compromise.

We can, once we’ve assessed the existing code, access, documentation, licenses and outstanding requirements. That review comes before any takeover scope.
