Timeline

4-phase implementation · Vestval One + Custom storefront

Impact

Single inventory and order graph across channels

Challenge

Store inventory, e-commerce and POS lived in three loosely-coupled systems. Same-day fulfilment was unreliable, the storefront was slow on mobile, and merchandising decisions were made on stale data.

Objectives

Single inventory and order graph across stores, web and POS
Materially faster mobile storefront, measurably better Core Web Vitals
Reliable same-day fulfilment in priority metros
Live merchandising signals instead of weekly batch reports

Approach

We rebuilt the order and inventory graph on Vestval One, shipped a headless storefront with image/route discipline, and re-sequenced fulfilment around live stock instead of nightly snapshots.

Solution

Vestval One as the system of record for inventory, orders and pricing. A headless storefront built for mobile-first performance. Store-ops apps for pick-and-pack with live inventory adjustments.

Implementation approach

1
Order & inventory graph first
Canonical order and inventory model designed and validated against six months of historical traffic before any UI work.
2
Headless storefront with image discipline
Storefront rebuilt with route-level code-splitting, image format negotiation and an explicit LCP budget per template.
3
Store-ops apps with live stock
Pick-and-pack apps for store associates writing back to live inventory, replacing nightly batch reconciliation.
4
Phased metro rollout
Rolled out by metro with same-day fulfilment turned on per metro only after pick accuracy crossed a defined threshold.

Technologies used

Vestval One
Headless storefront
Edge image pipeline
Store-ops mobile apps
Live inventory ledger

Outcomes

Single inventory and order graph across channels
Materially better mobile storefront performance (qualitative)
Same-day fulfilment reliability lifted in priority metros
Merchandising decisions moved from weekly to live

Lessons learned

Build the inventory graph first; the storefront is downstream.
Set an explicit LCP budget per template — it's the only way storefront perf survives feature pressure.
Roll out same-day fulfilment per metro on a threshold, never as a flag flip.
