We had a gnarly multi-tenant payments stack and zero appetite for another ‘rewrite in six months.’ Aristos owned the architecture, hit the dates, and our uptime story finally matched our pitch deck.

Multi-vendor marketplaces, custom Shopify apps, and high-conversion checkout—headless commerce, vendor payouts, and catalog search under load.
The vision
Commerce is conversion engineering under load. Checkout must feel instant; catalogs must stay consistent when a thousand vendors mutate inventory at once.
The challenge
Shopify and marketplace operators outgrow no-code apps—custom fees, multi-vendor payouts, and fraud rules need code, not kludged scripts.
How Aristos delivers
We ship custom Shopify apps, headless storefronts, and multi-vendor ledgers with explicit commission math. Search, recommendations, and inventory sync are observable systems—not cron prayers.
The Aristos standard
Engineering checklist we hold ourselves to—not a generic SLA slide.
- Cart and checkout flows resilient to race conditions and stale inventory
- Vendor payout schedules with holds, chargebacks, and tax-aware reporting
- Fraud signals (velocity, device fingerprint hooks) without blocking legit users
- A/B-ready event schemas for conversion analytics
Our toolkit
Elite tools we deploy by default for this practice area.
- Shopify Hydrogen / Custom apps · Medusa or custom Node commerce cores
- Stripe Connect · Redis for session carts · Meilisearch for catalog search
Engineering depth
- High-volume webhook ingestion with ordering guarantees per shop
- Marketplace moderation queues with SLA timers and appeal flows
- Seasonal scale tests before Black Friday–class traffic
