Ecommerce conversion product comparison: manual, software, managed and hybrid routes

This ecommerce conversion product comparison covers four procurement routes for an England adult-customer store journey: keep the manual process, buy software, commission a managed specialist, or run a hybrid.

Real options sit on each route. Shopify and WooCommerce cover store software, VWO and Optimizely cover testing, Stripe and Adyen cover payments, and Croud, Brainlabs and Conversion.com cover managed work. No route wins. The decision rests on evidence for one adult-customer journey and on gates that cannot be traded.

What to take away

The common England merchant case

The merchant defines a product-to-post-order route: approved product information, total price, basket, checkout and order placed. The next stages are payment authorisation and capture, then fulfilment and cancellation. Return, refund, dispute and support close the journey.

Geography means the operator and decision are in England; UK or Great Britain rules keep their real legal scope.

GOV.UK's online-selling guidance makes payment obligation, delivery options, correction and the total price relevant journey controls.

Published in November 2025 and updated in January 2026, the CMA's price-transparency guidance addresses what pricing information must include, plus drip and partitioned pricing. A route that weakens either is stopped before commercial comparison.

Compare the four named routes on identical fields

For each route, leave price, effort, duration, thresholds and weights blank. If money is later included, use the same currency, VAT basis, period and unit. Match term, limits and refund treatment too. Do not compare a monthly licence with an undefined project fee.

Named products and providers on each route

Quote-based entries have no public list price. The rest are published rates.

Google Optimize, the free testing tool many merchants used, closed on 30 September 2023. Testing now means a paid tier or an agency contract.

Agency rates are quoted, not published: retainers typically run from about £5,000 a month for one channel to £20,000 or more where research, build and media sit in one contract. Scope, test volume and data work drive that range.

Use a shared test envelope

Each external route must first supply its identity, exact edition, UK availability, support and contractual record. The common synthetic test then presents approved product and price evidence, plus missing and duplicate events.

It covers refused non-exempt tracking and payment authorisation and capture. Refund and dispute states follow, then an accessible task. The final stages are access removal, rollback, export and deletion. No production customer data is permitted.

ICO storage and access guidance makes refused tracking an operationally meaningful route. NCSC's online-service guidance supports scrutiny of identity, supply chain, logging, monitoring and incident handling. Those sources define review boundaries, not a pass for any candidate.

Preserve non-compensating decisions

Consumer price, privacy and PECR, accessibility and product safety are separate gates. So are payments, security, measurement validity, support and exit. A synthetic pass establishes only the recorded behaviour in that environment. It does not show lawfulness, customer benefit, sustained performance or causal uplift.

An observed rate also needs its eligible population, numerator and denominator. Period, timezone, missingness and post-order window matter too. HM Treasury's QPIE guidance explains why credible attribution depends on the comparison design. Supplier attribution is not automatically causal evidence.

Decision record

Select no route until the manual baseline and each admitted alternative have comparable fields. Record unknowns plainly. The merchant owner may later choose among candidates that clear every gate, but this comparison sets no universal winner and supplies no recommendation. Any material edition, contract, data-purpose or journey change returns that route to HOLD.

Before you act

Common questions

What does a synthetic test pass actually establish?

It establishes only the recorded behaviour in that environment. It does not show lawfulness, customer benefit, sustained performance or causal uplift. A pass is evidence of tested behaviour, not proof the route is legally sound or commercially better for the merchant.

Why must price and weights be left blank initially?

Leave price, effort, duration, thresholds and weights blank for each route. If money is later included, use the same currency, VAT basis, period, unit, term, limits and refund treatment. Comparing a monthly licence with an undefined project fee is not valid.

When should a route be returned to HOLD?

Any material edition, contract, data-purpose or journey change returns that route to HOLD. Select no route until the manual baseline and each admitted alternative have comparable fields, and record unknowns plainly rather than assuming them.

Which named options sit on each route?

Shopify, WooCommerce and BigCommerce sit on the software route. Croud, Brainlabs and Conversion.com sit on the managed route. Stripe and Adyen handle payments, and VWO, Optimizely and Contentsquare cover testing and measurement. A hybrid pairs one platform with a named agency contract, and the buyer keeps the account.
