Automation for UK ecommerce and DTC brands
Your Shopify works. Your 3PL works. Your helpdesk works. The gaps between them are eating an ops hire's worth of time every month. We close them.
Your stack runs. The people between it are the bottleneck.
For a UK DTC brand doing £2m–£30m in revenue, the platforms are rarely the problem. Shopify is fine. Klaviyo is fine. The 3PL is fine. What's expensive is the human stitching: someone reconciles refunds against orders, someone pulls returns data into a spreadsheet for finance, someone manually updates marketplace listings, someone copy-pastes the helpdesk macro that should already be triggered by the order tag.
- Refund-reconciliation drift — Stripe charges, Shopify refunds and Xero invoices fall out of sync. Finance spends days every month untangling the differences.
- Marketplace listing drift — A SKU goes out of stock on the warehouse system but is still live and selling on eBay and Amazon. Oversells, refunds, ratings drop.
- Helpdesk amnesia — Agents open a ticket and can't see the customer's last 3 orders, current shipment status or open RMA. So they ask. The customer types it again.
Plumbing first. Glamour last.
We don't migrate you off Shopify. We don't sell you a new ESP. We connect the platforms you already have so the workflow runs without humans copying data between them. Every build is reversible and built behind a feature flag — peak season is no time to launch.
- Platform-agnostic by design — Zero commissions or kickbacks from Shopify, Klaviyo, Gorgias or any 3PL. Our income is your fee, full stop.
- Staging-first, feature-flagged — Every integration lives in a staging environment with replayable sample orders before it ever sees production traffic.
- Your ops team owns it after — We pair-build with your ops lead. By handover they're confident extending the workflows we've shipped.
The seven highest-ROI builds we ship for UK ecommerce brands
We've done these enough times to know which ones pay back fast. Most ecommerce engagements pick 3–5 of these for the first build.
A four-phase engagement, priced flat
No hourly billing. No platform commissions. Fixed price for the project. You see the business case for each build before signing off.
We shadow your ops, CX and finance teams. Output: a map of every workflow, the top ROI candidates and the cost-saved estimate for each.
We pick 3–5 automations to build in priority order. You see the predicted hours saved, error reduction and revenue impact before approving.
Built in your stack of choice (n8n, Make, Zapier, custom) in a staging environment, behind feature flags. Your team in the room throughout.
Documentation, training, and a 90-day check-in to verify the predicted ROI was real. Retainer or done after that — your call.
What ecommerce automation actually means (beyond email)
If you Google "ecommerce automation" the first 100 results will be Klaviyo flow templates and Shopify Flow tutorials. Those are real and valuable, but they're the easy half of the problem. The bit that hurts at £2m+ revenue is the back-office automation: how a Shopify order becomes a 3PL pick, how a return becomes a refund, how a refund becomes an accounting entry, how a stock change ripples to every marketplace, how a customer support ticket sees the customer's whole history without an agent typing the order number into three different tabs.
That work doesn't fit neatly into Klaviyo or Shopify Flow. It lives in the spaces between your tools — and that's where the operational headcount goes.
The hidden ops tax on a growing DTC brand
The brands we work with most often are in the £2m–£30m revenue range. Above £30m you start to have a real ops team and the problem becomes a different shape. Below £2m the manual workarounds are usually fine — automating them is overkill. In between, the ops tax compounds:
- At £2m revenue you've probably got one ops person doing everything. They're stretched. The system is them and a spreadsheet.
- At £5m revenue you've got 2–3 ops/CX people. Half their time is spent on tasks a workflow should do — reconciling refunds, updating marketplace stock, triaging tickets that should be auto-tagged.
- At £15m revenue you're hiring an ops lead and an ops associate to run what should be a 1-person job with the right plumbing in place. Or you're hiring 4 CX agents when you'd need 2 if the helpdesk had a proper customer view.
- At £30m revenue you're seriously considering a head of ops engineering and an in-house developer. You should — but only after the foundational integrations are right. Hiring engineers to fix a mess of duplicated workflows wastes the engineers.
The ROI on automation is highest exactly in the £5m–£25m range. That's the sweet spot for a fractional CAO.
The UK ecommerce stack we typically work with
- Platform: Shopify (90% of the time), Shopify Plus, BigCommerce, Magento.
- Marketplaces: Amazon UK/EU, eBay, Mirakl, TikTok Shop, Etsy.
- OMS / inventory: Linnworks, Veeqo, Brightpearl, Cin7, ChannelAdvisor.

- Reviews & UGC: Okendo, Yotpo, Trustpilot, Junip.
We don't take partner commissions from any of these. If your current stack is the wrong fit we'll say so, but our default move is to make what you have work — not to drive a new licence sale.
What a Watermelon engagement looks like for an ecommerce brand
A scoped engagement is typically 6–8 weeks: 2 weeks of discovery, 1 week of strategy/sign-off, 4–6 weeks of building and shipping. The fixed price runs £8k–£30k depending on integration count and complexity. A typical £10m brand running Shopify, two marketplaces, one 3PL and Gorgias might land at £12k–£18k.
After the build, brands that want continuing operations leadership move to a fractional Chief Automation Officer retainer at £5k–£15k per month, usually 2–3 senior days a month. That covers continuous improvement, new integrations as the stack changes, peak-season prep and quarterly reporting on ops cost-to-serve.
We deliberately don't take agency-of-record contracts. We don't want to be running your Shopify forever — we want to build a system your in-house team can run.
