SECTION 01WHAT WE HEAR · ECOMMERCE
01 / SOUND FAMILIAR

Four problems we keep hearing
from growing ecommerce brands.

If two of these read like a description of your week, the fix is almost always the same shape — and almost never another plugin.

— ✕

Your theme has hit a wall.

Every change is a dev ticket. Page-speed is dropping. The platform’s roadmap doesn’t match yours — and nobody on your team is happy editing it any more.

Page-speed · theme limits · slow ticket loops
— ✕

Cart abandonment looks like leakage.

Checkout drop-off, broken pricing rules, feed disapprovals, mis-routed analytics — and no clear view of which one is actually costing you.

Checkout · feeds · pricing · attribution
— ✕

Five tools for one customer journey.

CMS, ERP, ESP, helpdesk, reviews, ad platforms — none of them agree on stock or who the customer is. Reporting is a Monday-morning manual job.

CMS · ERP · ESP · helpdesk · ad stack

Roadmap is at a vendor’s mercy.

You wait six months for a feature that should have been a Tuesday. The platform’s top-end use-case is your everyday — and your costs keep climbing with it.

Lock-in · waiting on roadmap · escalating costs
SECTION 02WHAT WE BUILD · ECOMMERCE
02 / THE BUILDS

Four shapes of work, matched to
your platform, your catalogue, your scale.

Most projects span two or three of these. We pick the platform that fits your roadmap — not the one we have on commission this quarter.

01

Shopify & Hydrogen.

Theme-2.0 storefronts when that fits, Hydrogen headless when scale demands it. Custom apps, checkout extensions, B2B, multi-currency — the un-glamorous parts most Shopify partners refuse.

  • Theme 2.0 + Hydrogen builds
  • Custom apps + checkout extensions
  • B2B · multi-currency · subscriptions
02

WooCommerce, built properly.

Real WooCommerce engineering, not page-builder bloat. Large catalogues, complex pricing rules, EU VAT and OSS, headless React frontends on top of a Woo data layer.

  • Catalogues > 50k SKUs
  • EU VAT · OSS · multi-currency
  • Headless React on top of Woo
03

Custom & headless.

When neither platform fits — marketplaces, multi-vendor, B2B portals, configurators, regulated goods. Ground-up, owned by you, no platform tax for the rest of its life.

  • Marketplaces + multi-vendor
  • B2B portals + configurators
  • Headless commerce stacks
04

Feed & conversion engineering.

Live feed pipelines (we own one — FeedPulse), CRO instrumentation, page-speed engineering, anomaly detection. The work that turns more of the visitors you already have into customers.

  • Feed transformation + channel sync
  • CRO instrumentation + analytics
  • Page-speed + Core Web Vitals

Two of those pains hit a nerve?
Let’s have a thirty-minute call.

No deck, no demo, no sales rep. A senior engineer, your real problem, an honest opinion on what to do about it.

How we work
SECTION 03WHY US · HOW WE WORK
03 / WHY US

We charge more, ship faster,
and we’ll tell you if we’re wrong for you.

Three things every Stackpulse engagement gets — and three reasons most of our intake comes from word of mouth.

Founder-led, kickoff to deploy.

No account managers, no offshoring. The senior engineer in the kickoff call is the one writing the code that ships. The CC list never grows.

NO HANDOFFS

No lite packages, no minimums you’ll regret.

If your build needs £30k+ of engineering to be done well, we’ll tell you. If it doesn’t, we’ll point you to a freelancer or platform partner who fits better.

HONEST FIT

Built to be handed over.

Every project ships with documentation, a runbook and a clean off-ramp. You own the code, the credentials, the Figma. If you leave, you take everything.

YOU OWN IT

SECTION 05OBJECTIONS · ANSWERED
05 / FAQ

The six questions every brand
asks us on the first call.

Cost, timeline, platform, ownership, post-launch — the answers usually surprise people. We’d rather you knew them before you book.

01Which platform should we be on — Shopify, WooCommerce or custom?
Depends on your catalogue size, B2B/B2C mix, integration complexity and roadmap freedom. We do not have a preferred platform — we have a preferred outcome. We tell you on the first call, with reasons.
02How much does a build cost?
Most ecommerce builds we ship sit between £25k and £120k. Custom platforms and headless builds run higher. We do not take sub-£10k projects — there is not enough time inside that budget to do the work well.
03How long does it take?
Typical Shopify build: 6–10 weeks. WooCommerce or fully custom: 10–20 weeks. We do not compress the discovery phase — that is where the build is won or lost.
04Will we own the work?
Yes. Every line of code, every credential, every Figma file. We are not a hosted-platform play and there is no platform tax. If you leave, you take everything with you.
05We already have a site that needs work — can you help?
That is most of our intake. We do platform migrations, replatforming, performance engineering, headless retrofits and post-launch optimisation. We will not insist on a rebuild if the existing stack can be saved.
06What happens after launch?
Optional retainer (£2k–£8k a month) covering ongoing engineering, feature work, monitoring and on-call. Most clients stay 18+ months. You can leave at any point.

Four steps. Repeatable.

Same shape for a one-week dashboard or a six-month platform build. The cadence stays — only the scope changes.
