Which service do you need?
Three quick questions, then the place to start and what it costs. Most people end up at the mini audit; the questions say when you shouldn't.
Your answers
Start with
GA4 mini audit
From £175 · 3 to 5 working days · Written report
Marc checks the parts of GA4 that most often break, and tells you what's wrong, what it's costing you and how to fix it, in a written report. Anything after it is quoted from the findings, so you only pay to fix what's actually broken.
Start with
Expert GA4 setup
Basic £350 to £600 · Advanced £850 to £1,300
GA4 and Google Tag Manager set up from a written measurement plan: key events, ecommerce or lead tracking, Consent Mode v2 and ad platforms, tested before launch and documented. Basic suits one website with straightforward tracking; advanced adds custom event design, detailed ecommerce tracking and cross-domain tracking.

Start with
Shopify GTM and GA4 setup
From £850
Shopify's checkout doesn't run your theme's code, so a pasted GTM container goes dark at payment. Marc builds GTM and GA4 across storefront and checkout, on Shopify's customer events, with Consent Mode v2 in place.

Start with
Google Tag Manager rebuild
£1,200 to £3,500
A container nobody dares touch is audited first, then cleaned up or rebuilt in stages, so reporting doesn't break while the work happens. A rebuild costs more up front and much less to maintain.

Start with
Consent Mode v2
Checked in the mini audit, from £175 · Built into every setup
Most Consent Mode setups look fine and fail quietly: defaults set too late, the wrong regions, or updates that never reach Google. Marc checks what your site loads before anyone agrees to anything and whether the banner's choices reach Google, then scopes the fix from there.

Start with
GA4 to CRM and back-office integration
£1,500 to £2,500 for a simple CRM connection
Leads and their source sent from the website into your CRM, and closed deals sent back to GA4, so revenue is credited to the campaign that started it. Designed around the systems you already have.

Start with
GA4 to BigQuery, then dashboards
BigQuery From £500 · Dashboards From £800
Every GA4 event exported to BigQuery, unsampled, built into usable tables that anyone with SQL can maintain, and reported in Data Studio or Power BI. The export comes first, because a dashboard built on unchecked data repeats its mistakes.

- Marc is independent of any agency. Findings are written so whoever runs your tracking can act on them, and he can brief them directly.
- Reports and setups are documented for the person who'll look after them, with a handover session where the work includes one.
- If nobody owns the tracking, the work is documented for whoever's next, and monitoring watches your key events and revenue every day so a site release doesn't quietly break it again.
- For an online shop the checks include the ecommerce events, so revenue and orders can be compared with what the shop platform reports. See GA4 for ecommerce.
- For a Shopify store the mini audit also checks the checkout tracking, which Shopify handles its own way. If the setup can't be saved, the Shopify setup starts again properly.
A pointer, not a diagnosis. The 20-minute intro call is free if you'd rather talk it through, and every price is on the pricing page.
How the answers are matched.
- Wrong numbers, duplicates, Direct traffic, or not sure. The GA4 mini audit. Finding the fault is cheaper than guessing at the fix, and the report says what to do next.
- Starting from scratch. The GA4 setup, or the Shopify setup for a Shopify store.
- A tangled container. The Tag Manager rebuild.
- Consent, CRM and data out of GA4. The matching service: Consent Mode v2, CRM integration, or BigQuery and dashboards.
- The website and who runs the tracking don't change the service. They add a note about what the work covers in your case.
Nothing you choose is stored or sent to Marc. With analytics cookies on, GA4 counts which answers are chosen and which service is shown, never anything about you. For a price range across a whole project, there's the cost estimator.
