Delivering a Commerce Platform Migration Against a Fixed Deadline
Client
Premium Beauty and Wellness D2C Brand | UK / European / US Fulfilment
The Situation
The business’s existing commerce platform contract had a fixed end date with no extension available.
The migration to Shopify had to be delivered on time while protecting three critical operational areas: fulfilment integration, subscription billing and the customer purchase journey.
The operational risk sat less in the product catalogue itself and more in the complexity of systems integration and timing.
What We DiD
Took ownership of the WMS integration and fulfilment architecture end-to-end
Managed the operational handoff for the subscription billing engine and recurring revenue workflows
Structured the migration as a direct cutover rather than a prolonged parallel-run process
Worked backwards from the immovable contract deadline to sequence every dependent operational workstream
Results
The migration delivered:
Successful cutover on the contractual deadline date
Approximately one hour of operational downtime
Full fulfilment and WMS integration operational from go-live
Subscription billing transferred without customer or revenue disruption
No observable negative conversion impact following launch
Post-launch conversion performance improved compared with the four weeks prior to migration.
Beyond the Numbers
The critical decision was treating the deadline as genuinely fixed.
Rather than allowing scope creep to force a contract extension, the operational plan was engineered around disciplined sequencing and execution.
By maintaining ownership of the fulfilment integration throughout the migration, the project protected the operational backbone of the customer experience during a high-risk systems transition.
