the change

Before

Customer experience for refunds, replacements, and post-purchase questions was spread across separate tools, and European shoppers were dropping off at checkout before payment.

01

Refunds, replacements, and post-purchase support lived across email, helpdesk, and back-office tools with no shared queue.

02

European checkout was missing a payment option that local shoppers expected, costing conversion at the last step.

03

Order, customer, and inventory data sat in disconnected systems instead of behind a single internal surface.

What we built

A customer experience hub now owns the refund, replacement, and post-purchase workflows, and a checkout change unlocked a payment method European shoppers actually use.

01

Led the build of a customer experience hub that owns refunds, replacements, and post-purchase support across multiple brands in one operating view.

02

Shipped Klarna checkout for European markets, contributing to a reported 10% lift in conversion.

03

Connected order management, customer data, and internal tooling so operations stopped pivoting between tabs and spreadsheets.

Controls

Every change has an owner, a fallback, and an audit trail.

01

Role-aware screens and audit trails for refunds, replacements, and post-purchase actions

02

Validation and idempotent updates on order, customer, and payment writes

03

Multi-brand boundaries kept clean inside the same operating surface

04

No public disclosure of brand-level revenue, exact order counts, or partner contract terms

book a workflow audit

Before you automate anything, find the workflow worth fixing.

A short call is the fastest way to figure out whether you need AI automation, custom software, integrations, or simply a clearer process.

workflow audit call

30 min

Bring one repeated process: a report, quote, approval, inbox, or handoff that keeps wasting time. We decide together whether it needs AI, software, integration, or just a cleaner process. No pitch.

or send details instead
01

We talk through one messy workflow

You describe where work starts, who touches it, what tools are involved, and where things slow down.

02

We decide if automation is even the right answer

Some problems need AI. Some need better process, clearer ownership, or a small internal tool. We separate them.

03

You leave with a practical next step

If there is a real opportunity, we outline the smallest useful build. If not, you avoid automating the wrong thing.
