Case study · Web Agency SaaS A Website QA Platform Built To Scale
QualityHive came to us with an idea and a waiting list. We built them a Laravel platform that web design and development agencies now use to capture bugs straight from a client's website, assign them to developers and close them off, and handed it over as clean, documented code.
The Brief
Agencies were collecting website feedback the hard way: long email threads, shared spreadsheets and screenshots pasted into documents. Nothing was assignable, nothing was searchable, and the same bug was often reported three times by three different people.
QualityHive needed a platform an agency could roll out to a client in minutes, with a browser extension that captures a bug straight from the page, complete with a screenshot, the exact URL and the browser and screen it happened on, and an API their clients' project tools could talk to.
What We Built
One platform, three jobs: capture a bug on the page, triage it with the team, prove it fixed to the client.
Point-And-Click Capture
A browser extension pins a bug straight onto the client's site, grabbing a screenshot, the exact URL and the browser, OS and screen size, so nobody has to describe where it happened.
Assignment And Triage
Every bug routes to a developer with a status, a due date and a full comment thread. Duplicates are caught as they are raised, on a board the whole team shares.
Client-Ready Reporting
Open bugs, resolution rates and project progress export as clean, branded reports, which is what QualityHive's own agency customers renew on.
Roles And Permissions
Agency, developer and client each see their own view of a project, with per-project access managed by the account owner.
Billing And Trials
Per-seat subscriptions, trial expiry and proration wired through Stripe, so the team can price without touching code.
A Documented API
A REST API with webhooks and written docs, so their customers' project tools can pull bug data without our involvement.
How We Ran It
Four stages, weekly demos, and direct access to the developer writing the code. No account managers in between.
Two workshops with real agency feedback in hand, then a written spec and a fixed quote.
Every screen agreed in grayscale before a line of Laravel, so changes cost minutes rather than sprints.
Fortnightly releases to a staging site the team could hand to pilot customers and comment on directly.
Repository, environment notes and API docs transferred, with a retained day a month for support.
The Result
QualityHive launched to their pilot agencies in week 14 and replaced the email-and-spreadsheet routine entirely. Feedback that used to take an evening to chase down is now captured in a click from the page it happened on, and the API means larger customers can pull bug data into their own reporting without asking anyone.
We still support the platform on a retained day a month, and the code sits in their repository, not ours.
We built QualityHive because website QA was still being run through email threads and spreadsheets. Now an agency captures a bug in a click straight from the page, assigns it and closes it off, all in one place. It has become the tool teams open first thing in the morning, which is exactly what we set out to build.

Case study · Retail Ecommerce From Magento To Shopify Plus
We had supported Clintons Cards on Magento 2 for years. When the platform started to hold the business back, we migrated the whole storefront to Shopify Plus, kept every integration running through the switch, and lifted both conversion and revenue in the process.
The Brief
Clintons Cards had been running on Magento 2 for years, a platform we knew inside out from supporting it day to day. It had become slow to change, expensive to host and awkward to extend, and every peak trading period turned into a stress test the business would rather not sit.
They wanted to move to Shopify Plus without losing a single order, customer record or product, and without breaking the integrations their operation depends on, including the stock and finance link into their internal financing platform.
What We Built
A clean Shopify Plus storefront, and the integration layer that kept the business running through the switch and after it.
Magento to Shopify Plus Migration
Every product, customer and historic order moved across to Shopify Plus, mapped and reconciled, so nothing was lost and customers noticed only a faster, cleaner store.
Order and Customer Sync
Orders and customer records flow between Shopify and the back office in real time, so the operation runs on one source of truth rather than nightly exports.
Product and Catalogue Integration
Product data, variants and pricing stay in step across systems, so the catalogue is managed once and is right everywhere it appears.
Stock and Finance Integration
A live link into their internal financing platform keeps stock levels and financials aligned, so what the store sells and what the business reports never drift apart.
A Resilient Peak
Shopify Plus takes the hosting and scaling worry off the table, so Christmas and Valentine's peaks are handled by the platform rather than a late night on call.
A Clean Handover
The store, the theme and the integration layer were documented and handed over, with us on hand through the first peak and beyond.
How We Ran It
A migration with no big-bang risk: mapped, staged, tested against real data, then switched over in a controlled cutover.
We mapped every Magento entity, integration and custom flow, using what we already knew from supporting the platform.
The Shopify Plus store and the integration layer were built and wired to a staging environment running real, anonymised data.
Products, customers and order history were moved and reconciled, with counts checked on both sides before anyone signed off.
A controlled switch with the integrations live from minute one, and us watching the first orders land.
The Result
Clintons Cards moved off Magento onto Shopify Plus with no lost data and no gap in trading. Conversion rate rose by over three percent and revenue was up fourteen percent, on a store that is faster to shop and far easier for the team to run.
The integrations that keep stock, finance, orders and customers in step came through the migration intact, and we still support the platform as the business grows.
Migrating a retailer the size of Clintons Cards is where these projects usually come unstuck. The volume of orders, customers and SKUs leaves nowhere to hide, but we moved the lot to Shopify Plus with the integrations live throughout, not a record out of place, and the store came out faster and trading better than it went in.

Case study · Food & Drink Ecommerce A Hot Sauce Brand Launched To Sell
The Sauce Foundry came to us as a startup with a great product and not much else. We built the brand, designed and built the store, sorted the product photography, and launched them to a 3.8% conversion rate from day one.
The Brief
The Sauce Foundry is an artisan hot sauce maker that arrived as a startup: a strong product, a founder with a vision, and no brand or store to sell it through. They needed the lot building from scratch, and they needed it to convert from launch, not eventually.
That meant more than a website. It meant an identity that looked established on day one, product photography good enough to sell a flavour through a screen, and a store built around the buy rather than bolted on after.
What We Built
A brand, a store and the photography to sell it, delivered together so nothing looked stitched from separate suppliers.
A Brand From Scratch
We shaped The Sauce Foundry's identity from the name outward, the logo, palette and voice, so a new maker turned up to market looking like it had been there for years.
A Store Built To Convert
A clean, fast storefront designed around the product and the buy, which is why it launched at a 3.8% conversion rate rather than slowly growing into one.
Product Photography, Sorted
Great sauce needs great photography, so we put them in touch with a photographer we trust and art directed the shots the store was built around.
Ready For Launch Day
Payments, shipping and stock were set up and tested so the very first order could land the moment the doors opened, not a week later.
Fast And Cached
Hosting tuned with server-level caching, so a small team is not paying enterprise bills and the store stays quick even when a new sauce takes off.
Room To Grow
Built on WooCommerce, so The Sauce Foundry owns the store outright and can add products, wholesale and subscriptions as the range expands.
How We Ran It
Brand first, then a store built around it, then a launch that was ready to sell from the first click.
We got to know the range, the maker and the customer, then agreed the brand direction and the shape of the store.
Identity, packaging cues and tone of voice, so the look was locked before a single page was designed.
The WooCommerce store designed and built around the products, with the photography we art directed dropped straight in.
Payments, shipping and analytics tested, then a clean launch, live and selling from day one.
The Result
The Sauce Foundry launched to a 3.8% conversion rate from day one, a figure plenty of established stores work years to reach. A brand new maker arrived at market looking the part, with a store that sold from the first visit.
We handled the brand, the build and the product photography together, and left them with a WooCommerce store they own outright and can grow into as the range and the business expand.
We came to Zestcode with a product and little else, and they handed us back a brand and a website we are genuinely pleased with. It looked the part from launch and, more to the point, it sold from launch.

Frequently Asked Questions
White Label WordPress Development for Agencies
If you are weighing up white label WordPress development, the questions that matter are usually practical: what can actually be built, whether it will stay easy to manage once your client has it, and whether we will stay out of sight while you own the relationship. Here is how we handle all three.
What white label WordPress development means for your agency
White label means every line of work is delivered under your agency's name. Your client sees your team, your branding and your project management. We stay behind the scenes, take our direction from you, and never make contact with the client unless you ask us to.
In practice this lets you take on WordPress work you could not staff internally, or smooth out the peaks when your own developers are already booked. You keep the client relationship, the margin and the credit, and you gain a development team that behaves as if it were part of your studio.
This sits alongside our wider white label web development work, so if a project runs beyond WordPress into other stacks, the same quiet, brand-neutral approach carries across.
We also work directly with businesses as a WordPress development agency where there is no agency in the middle. The build standards are identical; the only thing that changes is whose name is on the work.
The types of WordPress sites we build
Most of what we build falls into a few groups: marketing and brochure sites, content-heavy publishing sites, membership and gated areas, and sites with custom post types and structured content that the standard editor does not cover well.
We are comfortable with the awkward cases too, such as multilingual setups, sites pulling data from an external system, and builds where the client needs a genuinely simple editing experience rather than a page builder they will break.
If a project needs a shop attached, that usually moves into WooCommerce development, which we handle under the same white label arrangement so you deal with one team throughout.
Custom themes and bespoke plugins
We build custom themes rather than buying a commercial one and bending it to fit. That means clean markup, no unused code weighing the site down, and an admin that only shows the fields a client actually needs. It also means the next developer, ours or yours, can read the theme without unpicking someone else's shortcuts.
Where a site needs behaviour WordPress does not offer out of the box, we write a bespoke plugin for it rather than stacking third-party ones that overlap and conflict. A plugin keeps that custom logic separate from the theme, so a future redesign does not put the functionality at risk.
When a build needs to talk to a CRM, a booking system or another external platform, we handle the API integrations directly, including common ones like a HubSpot to WordPress sync.
Have a WordPress brief sitting on your desk?
Send us the scope and any designs, and we will tell you plainly what it involves and roughly what it would cost. No sales pitch, just a straight answer you can pass to your client.
Working from your designs and to your brand
Most of the time you bring the design, whether that is a full Figma file, a set of flats or an established brand you want carried through. We build to it faithfully, raise anything that will not translate cleanly to the browser before we start, and check back rather than guessing when a design leaves a state undefined.
We are used to working inside an agency's process, so we can slot into your project management, use your naming conventions and deliver in the format your team expects. If you would rather hand over the whole engagement, we also work directly with creative, design and marketing agencies on an ongoing basis.
Performance, testing and going live
Every site is built responsive and tested across the major browsers and devices before it goes anywhere near launch. We test with real content, not placeholder text, because long headings and missing images are what actually break a layout.
Performance is handled during the build, not bolted on afterwards. We keep the theme lean, load only what a page needs, and set up caching and image handling sensibly so the site is quick on first load. Where a project has demanding speed targets, our WordPress speed optimisation work goes deeper into it.
Launch is planned rather than rushed, with a checklist covering redirects, forms, tracking and backups, so nothing is discovered broken the morning after go-live.
Support after launch
A WordPress site is not finished at launch, it just changes shape. Plugins update, WordPress releases new versions, and clients ask for tweaks. Left alone, that is also how a site drifts into being slow or insecure.
We can hand a site over cleanly with documentation and step away, or stay on to handle updates, small changes and monitoring under your brand. Our white label WordPress support retainers are built for exactly this, giving your clients a dependable, branded care arrangement without you having to staff it.
If a site you did not build has run into trouble, we also take on recovery work such as WordPress hack repair, so you can offer your client a fix rather than turning the job away.
