An independent retailer's software bill is rarely the platform fee; it is the meters running on top. Email priced per contact, automation priced per task, a review app here and a subscription app there at £10-50 each, and analytics that quietly ships customer behaviour abroad. The better your store does, the more every meter charges, and the customer list you built lives in vendors' clouds on their terms.
What the metered stack costs a growing store
Shopify's UK list prices run Basic at £19-25 per month, Grow at £49-65 and Advanced from £259 (current UK list prices; check Shopify for yours). Klaviyo is reported around £45+ per month at 2,000 profiles and scales steeply with the list; Zapier is usage-tiered; Unleashed inventory is a verified $380 per month. WooCommerce, meanwhile, powers roughly a third of tracked online stores and more UK stores than Shopify (approximately 224k vs 166k, StoreLeads-derived; tracker methodologies vary, so treat the numbers as indicative).
| Capability | Metered stack | On Node (flat, hourly billed) |
|---|---|---|
| Storefront | Shopify Grow: £49-65 (current UK list; check Shopify) | WooCommerce on managed WordPress (Large): £75 |
| Email & automation | Klaviyo: ~£45+ at 2k profiles, scales steeply (reported) | Mautic (Medium): £45 at any list size |
| Analytics | GA4 consent workarounds, or paid privacy tools | Matomo (Small): £22 |
| Order-flow glue | Zapier: usage-tiered, ~£20-50+ | n8n (Medium): £45 |
| Store apps | Review, loyalty, subscription apps: £10-50 each | WooCommerce extensions, no monthly meters |
| Identity, SSO & audit | Per-app logins | Included with your apps: £0 |
| Indicative total | ~£150-250+ with every meter running | £187 flat at any list size |
Notice the crossover shape: it is driven by list size and app count, not headcount. At a small list the metered stack is cheaper; as contacts, orders and automations grow, the meters climb and the Node column does not move. An email list can grow to 100,000 contacts on Node for £0 extra. All figures are monthly equivalents of hourly billing against the published rate card, with no commitments.

What your store runs on Node
n8n and EspoCRM deploy self-serve, in minutes, from the signup portal (as do Nextcloud and DocuSeal); the rest below is managed setup, deployed and connected by our engineers.
Storefront: WordPress + WooCommerce (Large, £75/month equivalent, managed setup): your store on the platform that runs more UK stores than any other, patched, hardened and backed up by us on UK infrastructure. WooCommerce's official showcase features Weber, Mint Mobile, Scrub Daddy and UK tile retailer Mandarin Stone.
Email & marketing automation: Mautic (Medium, £45, managed setup): campaigns, flows and segmentation with no contact tier. We handle the sending relay and warm-up the deliverability depends on. Mautic's published case studies include the German drinks group Rotkäppchen-Mumm, which runs more than 40 brand sites on it.
Privacy-first analytics: Matomo (Small, £22, managed setup): first-party analytics on UK hardware, with cookieless options, as your GA4 exit. The European Commission's own analytics service, Europa Analytics, is built on Matomo, and UK public bodies including Ofqual disclose Matomo in their privacy notices.
Inventory & order back office: ERPNext (Large, £75, managed setup): stock, purchasing and order management, used by 30,000+ companies (Frappe, vendor-reported), against tools like Unleashed at a verified $380 per month.
B2B & wholesale invoicing: Invoice Ninja (Small, £22, managed setup): quotes and invoices for trade customers alongside the D2C store.
Order-flow glue: n8n (self-serve) (Medium, £45): connect store, courier, accounts and email with 400+ integrations and no per-task meter charging you for a good sales month. Other companies using n8n include the ecommerce marketplace Trendyol and Delivery Hero.
Customer data that stays yours, in the UK
Your customer list is the asset; the question is where it lives and who else profits from it. On Node it sits in your own network-isolated tenant on hardware we own in UK data centres, under UK jurisdiction, behind your own single sign-on, with admin actions audited and a UK GDPR Article 28 DPA as standard. First-party analytics via Matomo keeps behavioural data inside the same fence. No product makes you GDPR compliant, and we will not claim otherwise; this is infrastructure designed to support obligations that remain yours.
AI for product copy, without feeding a rival's model
Product descriptions, support reply drafts, review summaries: the AI gateway is OpenAI-compatible, and UK-hosted models run on GPUs we own, so catalogue and customer text never leaves our infrastructure. Metered per token in GBP on the same hourly invoice; see the model catalogue.

Frequently asked questions
How does the billing work compared with SaaS subscriptions?
Everything is billed hourly against a published rate card, with no minimum term and no contract; the monthly figures on this page are equivalents for an app running all month. Stop an app and the meter stops. Crucially there is no contact tier and no per-task meter: your email list can grow from 2,000 to 100,000 contacts for £0 extra.
Should we actually leave Shopify?
Not necessarily, and we will be straight about it: Shopify's checkout conversion, fraud tooling and app ecosystem are genuinely strong, especially for pure D2C velocity. The case for moving is the total stack cost once email, automation and apps are metered on top, plus owning your customer data. Some stores keep Shopify and move only email, analytics and automation to Node.
Is Mautic really a Klaviyo replacement?
Klaviyo is better out of the box, and Mautic deliverability needs proper warm-up and a sending relay, which our managed setup covers. What Mautic changes is the economics: a flat £45 per month equivalent at any list size, against contact-tiered pricing that climbs steeply as the list you worked to build grows.
Who keeps WooCommerce patched and secure?
We do; that is what managed hosting is. WooCommerce genuinely needs updates, hardening and backups that Shopify handles invisibly, so we handle core and plugin updates, TLS, firewalling, monitoring and backups on UK infrastructure. We will not pretend it reaches checkout parity with Shopify by itself; we do make the maintenance argument disappear.
What about analytics and UK GDPR?
Matomo runs in your own tenant, so analytics data is first-party, stays on UK hardware, and can be configured for cookieless tracking. Against GA4's consent and data-transfer headaches, that is a materially easier privacy story, and it is a flat £22 per month equivalent rather than a paid tier of someone else's cloud.
What does a typical stack cost, and where is the crossover?
Storefront (Large, £75), Mautic (£45), Matomo (£22) and n8n (£45) is £187 per month equivalent plus VAT with no platform fee, billed hourly with no minimum term. Against Shopify Grow plus Klaviyo plus a review app plus Zapier at roughly £150-250 with meters running, the crossover comes as your list and order volume grow, not your headcount.
