Case Study

Herringbone & Sui

Sep 2017 to May 2020

4.8x revenue growth. End-to-end digital transformation for a premium menswear brand. Strategy covered e-commerce, process automation, CRM, marketing, and global B2B partnerships. Operational error rates collapsed: cancellations down 75%, procurement errors down 99%, styling errors down 85%, on-time delivery up from 77% to 93%.

The challenge

A premium brand with no digital backbone.

When the engagement started in 2017, Herringbone & Sui's stylists were filling out paper forms, the production team was running on innumerable files and weekly meetings, and runners were physically moving documents between stores and the production unit. There was no digital order history, no e-commerce of consequence, and no track of production. Product, taste, and customers existed; the operating system did not.

The solution

Eight proprietary systems, one operating model.

01Custom-built e-commerce portal (own stack, not Shopify)
02Style App: POS and invoicing system for stores and B2B partners (responsive web app)
03Custom CRM with marketing automation and history-driven mailing triggers
04Production management system using QR codes and RFID for accuracy and automated planning
05Procurement and inventory management deeply integrated with production, POS, and accounting
06Accounting and reconciliation system for finance
07Reporting dashboards for management, sales staff, and department heads
08Internal training modules for sales staff with video and text content
09B2B version of the POS and invoicing system for tailors and boutique stores in US, Canada, and UK
Scope

Three years. One transformation.

Strategy

Mapped the full consumer journey, designed a communication and data architecture plan, instituted reporting benchmarks and dashboards, and optimized the social media and SEO posture. The 360-degree advertising and communication plan has been on auto-pilot since December 2017.

A model engagement for the digital transformation practice.

The Herringbone & Sui engagement is the canonical example of how Passer connects strategy to delivery: from advisory to build to growth, all under one accountable team. Just before the pandemic, a B2B version of the POS and invoicing system shipped to tailors and boutiques in the US, Canada, and UK, a brand-extension play that turned operational tooling into a revenue line.

Platform connection

No platform required.

Some engagements use our platforms. This one was a pure build. The Passer engineering and growth teams shipped everything end-to-end.
