How we think

Plan. Integrity. Reporting.

Three principles run through every analytics engagement we take on. They are the difference between a tag install and a proper analytics function.

Plan

Plan for measurable revenue.

We start every analytics engagement with a measurement plan, not a tag install. Which events matter, which parameters they need, what they trigger downstream, and how each one ties to revenue. Without that plan, you are configuring tools, not building analytics.

Integrity

Build data you can actually trust.

Server-side tagging, Consent Mode v2, internal traffic filters, validation across DebugView and the platform of record. Real data quality, the kind that makes finance and marketing finally agree on the numbers, not the kind agencies put in slides.

Reporting

Reporting that drives action.

Looker Studio dashboards your team will actually open. Trading reviews against the metrics that matter. BigQuery for the analysis GA4 cannot do. Reporting that connects marketing spend to revenue, not vanity metrics that nobody can defend.

What we offer

Four ways we work with you.

Project, fixed price

GA4 audit

A full audit of your GA4 setup. Delivered in ten working days.

We audit every aspect of your GA4 property: event taxonomy, ecommerce tracking, conversions, attribution, audiences, BigQuery export, and Consent Mode. You receive a written report with every issue, ranked by impact, plus a remediation plan with effort estimates.

For brands who suspect their GA4 numbers are not telling the full story.

What you get

  • Full GA4 property and data stream audit
  • Event and parameter taxonomy review
  • Ecommerce event validation against the platform of record
  • Conversion / key event configuration review
  • Consent Mode v2 implementation check
  • Internal traffic, bot, and quality filter review
  • Written report with prioritised remediation plan

Project, fixed price

GA4 implementation

A full GA4 build, from data layer to dashboards.

A complete GA4 implementation tailored to your platform and tech stack. We design the data layer, build the GTM container, fire every recommended ecommerce event, configure conversions and audiences, link Google Ads and Search Console, set up BigQuery, and validate the entire setup against revenue from the platform of record.

For brands rebuilding GA4 from scratch, or fixing a broken inheritance.

What you get

  • Measurement plan and event taxonomy
  • Data layer specification and engineering brief
  • GTM web container build and deployment
  • Full ecommerce event suite with items array
  • Custom event and conversion tracking
  • Google Ads, Search Console, BigQuery linking
  • QA against Shopify, Magento, or platform of record
  • Documentation handover for your team

Project, fixed price

Server-side tagging

Move marketing tags to a server you control.

We deploy a server-side GTM container on a first-party subdomain (your domain, your control), route GA4, Meta CAPI, TikTok Events API, and Google Ads through it, and rebuild your marketing data flow with stronger first-party signal, lower data loss, and better page performance. Stape or self-hosted, your call.

For ecommerce brands spending £5k+/month on paid media who suspect their data quality is hurting performance.

What you get

  • Server-side GTM container build
  • First-party subdomain (sst.yourdomain.com) setup
  • GA4 server-side routing
  • Meta Conversions API (CAPI) integration
  • TikTok Events API integration
  • Google Ads enhanced conversions
  • Identity, consent, and PII handling
  • Data quality validation and dashboards

Project + retainer

BigQuery & Looker Studio

A real data warehouse and dashboards your team will use.

Free GA4 BigQuery export turned on, a structured data warehouse built around your business logic, and Looker Studio dashboards designed for marketing, finance, and product teams. We build the queries, the data models, and the dashboards. We also train your team to update them.

For brands who have outgrown GA4 standard reports and need real warehouse-level analysis.

What you get

  • GA4 to BigQuery export setup
  • Shopify, Stripe, Klaviyo, ad platform integrations
  • Data warehouse modelling (raw, staging, mart layers)
  • Custom SQL views for marketing, finance, product
  • Looker Studio dashboard suite
  • Trading review templates
  • Documentation and team training

Why us

Specialist work, plain-spoken delivery.

We are a small team of senior consultants. We do four disciplines, properly. We are direct, technical, and we genuinely care whether your numbers move.

  1. Senior people, no junior handover

    The senior consultant who responds to your enquiry is the senior consultant who builds your data layer. There is no account team filtering messages, no junior delivery, no agency theatre.

  2. Honest reporting against actual revenue

    We report against the platform of record (Shopify, Magento, your ERP) every month. If our numbers do not reconcile with your finance team, we explain why. No hiding behind platform-reported metrics.

  3. Specialists, not generalists

    We do four things and we do them very well. We will not pitch you brand strategy or PR. If we think your problem sits outside our wheelhouse, we will say so in our first reply.

  4. No long lock-in contracts

    Three-month minimum on retainers, then monthly rolling. If we are not delivering value, you do not stay. We have never had to enforce a notice period.

FAQs

Common questions about GA4 work.

Is the GA4 audit really fixed price?
Yes. After you send us a message via the contact form we quote a fixed price within one business day, scoped to the size and complexity of your property. No add-ons, no scope creep. You get a written audit covering every aspect of your GA4 setup, with prioritised issues and a remediation plan you can act on independently or with us.
How do your prices compare to other agencies?
Our Foundation tier sits comfortably in the middle of the market for specialist analytics retainers. We sit well below London tier-1 agencies whose entry retainers typically start north of £8,000 a month, and roughly in line with the strongest specialist agencies elsewhere in the UK. The difference is who delivers the work. Senior people scope your audit, senior people run your QA, senior people answer your Slack messages. There is no junior pool subsidising the rate. If you are choosing between us and a £500-per-month freelancer or a £1,000-per-month generalist, you are comparing two different things.
Why are your retainers more affordable than London?
Because we are not based in London. Our team works from Worksop, Nottinghamshire, with a remote-first operating model. We do not carry Soho rent, oversized account-management layers, or expense accounts dressed up as strategy. The cost saving goes back into the work and your bottom line.
How do I get started?
Send us a message via the contact form with a few sentences about your business and what you are trying to solve. We review your GA4 property and ad accounts before responding, and within one business day you will have a written assessment from a senior consultant covering what is broken, what to fix first, what it would cost, and whether we are the right people to do it. No follow-up sales sequence, no SDR, no "let me circle back with the team".
Can you take over a GA4 setup someone else built?
Yes. Most of our retainers start this way. We audit what is there, document the issues, propose a remediation plan, and either fix or rebuild depending on what the audit finds. Inheriting other agencies' work is something we do every week.
Do you work with Shopify, Magento, headless?
All three, plus Salesforce Commerce Cloud, BigCommerce, and bespoke platforms. The data layer specification is platform agnostic. We have specific reference implementations for Shopify Plus, Hydrogen, Magento 2, and headless Next.js stacks.
Do I need to be on the Growth tier to do server-side tagging?
No. Server-side tagging can be a one-off project, quoted on a fixed-price basis, and then maintained on Foundation. It is included in Growth as standard because most brands at that level already have it or need it.
What size of brand do you typically work with?
Our retainer clients tend to do at least £2 million in annual ecommerce revenue. Some do hundreds of millions. The common thread is that data quality matters to the business, not the size of the business. If you are doing serious revenue and your numbers are not reconciling, we should talk.

Bring your numbers.
We will tell you what they actually mean.

Send us a message via the contact form. We will look at your GA4 property and ad accounts and respond within one business day with what is broken, what to fix first, and what it would cost.
