Head Of Ecommerce Stack Audit Worksheet Checklist
A quarterly worksheet for Heads of E-commerce to audit every CRO and analytics tool by cost, last login, and the last real decision it drove — then cut, downgrade, or renegotiate.
Head of E-commerce Stack Audit Worksheet
A quarterly line-item worksheet that audits every CRO and analytics tool by cost, usage, insights, and a cut/downgrade/renegotiate decision.
The Head of E-commerce Stack Audit Worksheet is a recurring, quarter-close review of every paid tool touching your CRO and analytics stack — GA4 add-ons, heatmap tools, A/B testing platforms, session replay, survey widgets, and the plugins glued between them. Each row captures license cost, seats in use, last login, the last decision the tool actually drove, and dev-hours consumed.
The output isn't a report — it's three columns of action: cut, downgrade, or renegotiate. Run properly, it typically reclaims 15-30% of stack spend on a €1M-€15M Shopify or WooCommerce store without losing a single working experiment.
Most CRO stacks weren't designed — they accumulated. A heatmap tool got added during a landing-page project two years ago. A survey widget came with an agency engagement that ended in Q3. A second A/B testing seat was bought when someone left and never got reassigned. Nobody owns the total.
The worksheet forces the total into view. One tab, one row per tool, run 90 minutes before every quarterly planning meeting. The point isn't to cut aggressively — it's to make renewal a conscious decision instead of a Stripe autopay.
The one rule that makes the worksheet work
Every row must end with a decision — cut, downgrade, or renegotiate. "Keep as is" is not an option. Forcing a decision on every tool, every quarter, is what breaks the autopilot.
The eight columns every row needs
1. Tool name and category. Group by function — analytics, heatmap, A/B testing, session replay, survey, feedback, tag management. This is how you spot overlap fast, and it feeds directly into the Hotjar vs VWO vs GA4 feature overlap matrix you'll run on audit day.
2. Annual license cost and seats in use. Pull the invoice, not the plan page — vendors quietly raise prices at renewal. Then divide by seats actually logging in. A €12,000/year tool with two active users is a €6,000/user tool, and that's the number the CFO will remember. Cross-check against the quarterly stack-spend benchmark for €1M-€15M Shopify stores to see if your total is in the normal band.
3. Last login, per seat. This is the 90-day last-login rule for cutting CRO tools in one column: if no seat has logged in for 90 days, the tool is effectively dead weight. Most vendors expose this in an admin panel; if they don't, that's itself a signal.
4. Insights surfaced this quarter, and 5. the insight-to-license-cost ratio. Count concrete findings the tool produced — a checkout drop-off spotted, a mobile bug caught, a winning variant. Divide license cost by insight count. The per-tool insight-to-license-cost ratio threshold most Heads of E-commerce use is roughly €500 per insight; above that, the tool is on notice.
6. Dev-hours consumed. The hidden line item. A tool that needed 20 hours of engineering time this quarter to keep its tracking working costs far more than its invoice. Counting dev-hours per tool as a worksheet line item routinely doubles the true cost of the cheapest-looking tools in the stack.
7. The last decision this tool drove — named. Not "provided insights" — the specific decision. Which variant shipped, which page got redesigned, which segment got a new email flow. If you can't name the last decision a tool drove, that's the cut signal. 8. The outcome column: cut, downgrade, or renegotiate — one of three, chosen using the cut vs downgrade vs renegotiate decision rule and sequenced against sunk-cost bias on annual CRO tool renewals, which is what usually keeps a dead tool on the invoice.
Frequently asked questions
About 90 minutes for a stack of 8-12 tools, once the template is populated. The first run takes 3-4 hours because you're pulling last-login data and invoices from each vendor for the first time. Subsequent quarters take 60-90 minutes.
The Head of E-commerce owns the worksheet and the final cut/downgrade/renegotiate call, because it's a budget document. The CRO specialist populates the insight and last-decision columns, since they know which tool actually surfaced what.
A specific, dated finding that changed a decision — a funnel step that dropped 8% on mobile, a form field that killed submissions, a variant that won at 95% significance. Vanity dashboards and generic reports don't count. If you can't point to a Slack message or ticket, it wasn't an insight.
Yes. The categories are the same — analytics, heatmap, A/B testing, tag management — the vendors just differ. WooCommerce stacks tend to carry more plugin-based tools with lower per-license costs but higher dev-hour columns.
Split the bundle into logical rows using the vendor's own line-item breakdown, or apportion cost by seats or feature usage. If the vendor won't unbundle, treat the whole suite as one row and evaluate against combined insights.
That's a downgrade candidate, not a cut. Move to the cheapest tier that preserves data export, and set a 6-month deadline to migrate history elsewhere. Sequencing cuts to avoid losing historical data is a common trap on this worksheet.
Yes — the license is free, but dev-hours and insight-quality columns still apply. A "free" tool that eats 15 dev-hours a quarter isn't free. And it forces you to check that the tools you're paying for are meaningfully different from what GA4 already tells you.
The worksheet is your leverage. Walking into a renewal call with usage data, insight counts, and a documented downgrade tier gives you a real BATNA. Vendors will discount 15-30% when they see you have the numbers.
No login in 90 days combined with no named decision it drove in the last quarter. Those two columns together resolve about 40% of cut decisions before you even look at cost.
When three or more tools show overlapping capabilities and the combined insight-to-cost ratio is above your threshold, it's time to consolidate the fragmented CRO stack rather than trim it row by row. The worksheet feeds directly into that decision.
