Ecommerce Website Development That Does Not Cost You The Traffic You Already Had
Techzenix builds and rebuilds online stores without losing what the old site earned. Most redesigns look better and sell less, because nobody mapped the URLs, tested the checkout or asked what the traffic was doing before.

We build stores judged by revenue per session.
Techzenix is an ecommerce development company that designs, builds and migrates online stores. Ecommerce website development covers platform selection, storefront design, checkout and payment integration, catalogue structure and the migration work that protects existing rankings. As an ecommerce web design agency we work with direct to consumer brands, multi channel retailers and B2B sellers across the United States, United Kingdom and Europe. Online store development is judged here by revenue per session after launch, not by how the homepage looks.
Why most ecommerce rebuilds lose money.
A rebuild is the single most dangerous project an online store can undertake. Four things go wrong, and they go wrong on most projects.
Nobody maps the old URLs
Every product, category and content page on the old site has an address that Google knows and that other sites link to. When the new site launches with different addresses and no redirect map, all of that disappears overnight. Traffic drops, and because it drops after launch rather than during, it gets blamed on seasonality. This is the most common and most expensive mistake in ecommerce web development, and it is entirely preventable.
Design and build, one engagement.
Our ecommerce website development services and ecommerce web design services are delivered as one engagement, because splitting design from build is where most problems start.
Platform selection
An honest recommendation based on catalogue size, B2B requirements, integrations and internal capability, including the platforms we would rule out.
One caveat. Custom ecommerce development services are available where an off the shelf platform genuinely cannot do the job. We will tell you when it can, because a custom build you did not need is the most expensive mistake in this category.
Who we build for.
Custom ecommerce development means different things depending on what you sell and who you sell it to.
Direct to consumer brands
Speed, mobile checkout and merchandising. Usually a platform build rather than custom ecommerce web design, because the requirements are well served already.
What this looks like in practice.
Their previous agency had quoted a rebuild with no mention of redirects. The store had eleven years of accumulated links and rankings, and roughly 38,000 indexed URLs.
Techzenix mapped every legacy URL to its new destination before the build started, migrated the catalogue with variant structure intact, rebuilt checkout for mobile first, and connected the ERP so stock was accurate at the point of sale rather than at the end of the day.
- Organic sessions41,000 per month→0 per month
- Legacy URLs redirectednot planned→0 of 38,100
- Largest Contentful Paint5.1 seconds→0.0 seconds
- Mobile checkout completion38 percent→0 percent
- Revenue per session$1.84→$0.00
Organic traffic went up slightly rather than down. That is the goal of a migration. Most rebuilds treat a 20 to 30 percent drop as normal, and it is not.
Four stages, and a redirect map live from minute one.

Review
We look at your current store, your traffic, your checkout data and your integrations. If a rebuild is not the right answer we will say so, and explain what to fix instead.
- 02
Plan
Platform recommendation, redirect map and Core Web Vitals targets agreed in writing before any design work begins.
- 03
Build
Design and development run together, with checkout and mobile treated as first class rather than last. You see working pages, not slides.
- 04
Launch
Staged cutover with the redirect map live from minute one, rollback ready, and rankings monitored daily for the first month.
Why brands choose Techzenix.
We plan redirects before we design anything
The redirect map is agreed in writing at the start of the project. It is the difference between a migration and a loss.
We will tell you not to rebuild
Plenty of stores need a checkout fix and a speed pass, not a new site. As an ecommerce website development agency that costs us the larger project, and we say it anyway.
We name the platforms we would not use
For your specific catalogue, integrations and team. A recommendation without an exclusion is not a recommendation.
We hand over something you own
Documentation, training and code you control. No dependency on us to add a product or edit a page.
What ecommerce web development costs with Techzenix.
Straight talk. If your store is under roughly $30,000 monthly revenue, a full rebuild is rarely the right spend. A checkout audit and a performance pass usually return more, and we would rather sell you that.
Ecommerce Development FAQs
An ecommerce development company designs, builds and migrates online stores. That covers platform selection, storefront and checkout design, catalogue structure, payment and shipping integration, and the redirect work that protects existing search rankings during a rebuild.
Platform builds typically run $10,000 to $40,000 depending on catalogue size and integrations. Custom ecommerce website development starts higher, usually $40,000 and above. Ecommerce web design packages for small catalogues can be under $10,000. Any quote given before someone has looked at your integrations is a guess.
It will if the old URLs are not mapped to the new ones. This is the single most common cause of traffic loss after a relaunch. Ask any ecommerce web design company how they handle redirect mapping before you sign. If the answer is vague, expect a drop.
It depends on catalogue size, whether you sell B2B, what you need to integrate and who maintains the site afterwards. Shopify suits most direct to consumer brands. WooCommerce suits stores that need deep customisation and have technical support. BigCommerce suits larger or B2B catalogues. The right answer for you is not the same as the right answer generally.
Ask three questions. How do you handle redirects during migration. Which platform would you rule out for us and why. What Core Web Vitals targets will you commit to before we start. An agency with clear answers has done this before. One that talks mainly about design has not.
Yes. B2B ecommerce website development needs customer groups, negotiated price lists, quote workflows, net terms and purchase order handling. It is a materially different build from consumer ecommerce, and it should be quoted as one.
