Every agency hits that moment: a client wants an eCommerce website, the deadline is impossibly tight, and your in-house team is already stretched. Say yes and risk quality. Say no and lose the project — and possibly the client.
That was exactly the situation one of our agency partners faced last year. Their client, a specialist industrial products retailer with over 200 SKUs, needed a full WooCommerce store live within three weeks. The agency had the client relationship and the marketing expertise, but not the development capacity to deliver at that pace.
So they called us.
This is the story of how we took that project from initial spec to a fully launched, 40-page eCommerce site — on time, on budget, and completely invisible to the end client. We’ll walk you through the timeline, the challenges, and the specific decisions that made a seemingly impossible deadline entirely achievable.
The Brief
Our partner — a mid-sized marketing agency based in the Midlands with about 15 staff — had been working with their client for around 18 months on SEO and paid media. The campaigns were performing well, driving solid traffic, but the client’s existing Shopify store wasn’t converting.
It was slow, difficult to update, and completely disconnected from their content marketing strategy.
When the client decided to rebuild on WordPress for better SEO integration and content flexibility, the agency saw an opportunity to deepen the relationship. They could own the whole digital presence — marketing and the website — rather than just running ads to someone else’s site.
The problem? They didn’t have a web development team. Their previous attempt at outsourcing a build to a freelancer had gone badly: missed deadlines, poor communication, and a site that needed significant rework.
What the client needed:
A 40-page WordPress site with WooCommerce
Over 200 products imported, categorised, and properly structured
Integration with their existing marketplace listings (Amazon and eBay)
Custom product filtering, search, and attribute-based navigation
A blog section optimised for their ongoing SEO strategy
Mobile-responsive design matching their existing brand guidelines
SSL, WP Engine hosting setup, and DNS migration from the old platform
The whole thing live in three weeks — they had a trade show coming up
That’s a big ask for any team. For an agency without developers, it sounds impossible. But this is exactly the kind of project we handle every week.
Our Process: Spec to Launch in 21 Days
We follow a structured delivery process for every project, regardless of size. For this build, the timeline looked like this:
Week 1: Specification and Design (Days 1–5)
On day one, our project manager joined a briefing call with the agency (not the end client — that’s how white-label works). We reviewed the brand guidelines, the existing Shopify store, the product catalogue, and the key pain points with their current setup.
By day two, we had a detailed specification document covering every page, every feature, and every integration point. This wasn’t a vague brief — it mapped out the exact page structure, WooCommerce configuration, product attribute taxonomy, and the user journey from landing page through to checkout. The agency reviewed and approved it within 24 hours.
Our design team then produced full-page mockups for the key templates: homepage, product category pages, individual product pages, the blog layout, the contact page, FAQ, and the delivery information page. Seven unique templates in total, each reviewed against the client’s brand guidelines and optimised for conversion.
The agency fed back minor colour and layout tweaks on day four. We turned the revisions around the same afternoon. No back-and-forth — the detailed spec had already aligned expectations.
End of week one: Full spec signed off. All page designs approved. Development ready to start.
Week 2: Development and Product Import (Days 6–12)
This is where the heavy lifting happened.
Our development team built the site on WordPress with Elementor and WooCommerce, working from the approved designs. We set up the product architecture first — categories, attributes, variable products, and filters — because getting the taxonomy right from the start saves hours of rework later. For this project, we configured custom product attributes for size, material, and application type, with layered navigation so visitors could filter products intuitively.
The product import was the biggest single task. The client’s data sat in a messy spreadsheet: inconsistent formatting, missing descriptions, duplicate entries, and product images stored across three different folders with no naming convention. Our team spent a full day cleaning and restructuring the data, then wrote a custom import script to load all 214 products with their images, descriptions, pricing, variations, and category assignments. Every product was verified post-import.
Meanwhile, we built out the remaining static and dynamic pages: About, Services, FAQ, Delivery Information, Returns Policy, Terms and Conditions, Privacy Policy, and the blog templates with category archives. Each one matched the approved designs pixel-for-pixel. We also configured
RankMath for SEO, set up the XML sitemap, and added schema markup for products.
We ran our first internal QC review on day 10 — checking every page on desktop, tablet, and mobile. Every link, every form, every add-to-cart button, every product variation. Our QC process caught 23 issues ranging from minor spacing inconsistencies to a checkout flow problem on Safari. All fixed before the agency ever saw the site.
End of week two: Fully functional site on our staging server. First QC round complete. Zero known issues. Sent to the agency for review.
Week 3: Client Review, Revisions, and Launch (Days 13–21)
The agency reviewed the staging site with their client on day 13. They presented it as their own work — as planned. Feedback came back on day 14 — mostly minor content tweaks, a request to adjust the product filtering layout on mobile, and a couple of additional product images to swap in.
We turned the amends around in a day and a half, then ran a second full QC pass. Every product rechecked. Every page retested across Chrome, Safari, Firefox, and Edge on both desktop and mobile. Core Web Vitals were optimised — we hit green scores across the board. SSL was configured and forced across the entire site.
On day 18, we ran through our comprehensive go-live checklist with the agency: DNS records, MX records for email routing, 301 redirects from every old Shopify URL (critical for preserving their SEO equity), Google Analytics 4 and Search Console setup, WooCommerce payment gateway testing with live transactions, and email notification configuration.
We migrated DNS on day 19 and monitored the site 48 hours post-launch, watching for any issues with caching, SSL propagation, or email delivery.
End of week three: Site live. Client happy. Agency looking like heroes — just in time for their trade show.
The marketplace integration (syncing inventory with Amazon and eBay listings) was completed in a follow-up phase during week four, keeping the core launch on schedule while adding the final piece of the puzzle.
The Numbers
Here’s what we delivered:
| Metric | Detail |
| Total pages | 40 (including product category and policy pages) |
| Products imported | 214 |
| Design templates | 7 unique layouts |
| Development hours | 84 |
| QC rounds | 2 full passes |
| Timeline | 21 calendar days, spec to launch |
| Budget | On budget — no scope creep, no surprises |
| Client revisions | 1 round of minor amends |
For the agency, the project generated over £8,000 in revenue at their client-facing rate — with healthy margin built in because they weren’t paying for an in-house team.
What Made This Work
Three things made this tight timeline possible:
1. A clear process from day one
We didn’t wing it. Every project follows the same structured workflow: spec → design → development → QC → client review → amends → final QC → launch. This isn’t bureaucracy — it’s what lets us move fast without cutting corners.
2. Parallel workstreams
While our developer built the site framework, another team member was cleaning and preparing the product data. Our QC specialist started testing as soon as the first pages were ready, not after everything was finished. Overlapping workstreams compress timelines dramatically.
3. A single point of contact
The agency dealt with one project manager on our side. No chasing multiple freelancers. No wondering who’s doing what. One person who owned the project from spec to launch and kept everything on track.
This is the difference between outsourcing to freelancers and working with a dedicated white-label partner. Freelancers can build websites. But consistently delivering complex projects on tight deadlines — while staying invisible to the end client — requires systems, process, and a team that’s done it hundreds of times.
The Result for the Agency
This project didn’t just deliver a website. It changed how the agency operates.
Before working with us, they’d been turning down web projects or subcontracting to freelancers with mixed results. They’d lost at least two clients who wanted websites the agency couldn’t provide. Since this build, they’ve referred six more web projects to us — including two more eCommerce sites and a large brochure site with a custom booking system.
They’ve added website design and development as a core service on their own website. They’re quoting web projects confidently, knowing they have a reliable delivery partner behind them. Web services now account for roughly 30% of their monthly revenue — revenue that simply didn’t exist before.
Their client? They renewed their marketing retainer for another 12 months, partly because the agency “built” them such a brilliant website. The site’s improved speed and SEO structure also gave their existing campaigns a measurable performance boost — lower bounce rates, higher conversion rates, and better quality scores on their Google Ads.
The agency keeps the relationship. We stay behind the scenes. Everyone wins.
