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.

B2B Marketplaces & Directories
B2B wholesale platforms, vendor onboarding, and service directories—RFQ flows, contract pricing, and operator tooling at scale.
The vision
B2B marketplaces are trust, terms, and logistics in one graph. Buyers expect contract pricing, credit limits, and proof of fulfillment—consumer checkout patterns alone will not close a six-figure PO.
The challenge
Wholesale and service directories drown in bespoke Excel sidecars: tiered pricing, MOQs, territory rules, and vendor onboarding that never made it into the data model.
How Aristos delivers
Aristos ships B2B portals with RFQ workflows, approval chains, and directory search that respects org boundaries. Service marketplaces get scheduling, escrow-style milestones, and dispute states operators can audit.
The Aristos standard
Engineering checklist we hold ourselves to—not a generic SLA slide.
- Vendor KYC and tiered onboarding with document retention you can defend
- Price lists, contracts, and volume breaks modeled explicitly—not hidden in notes fields
- Order state machines with partial fulfillment, backorders, and ASN hooks
- Operator dashboards for disputes, payouts, and SLA breaches
Our toolkit
Elite tools we deploy by default for this practice area.
- Next.js · PostgreSQL · Elasticsearch / Typesense for faceted vendor search
- Stripe Connect–class splits or custom payout batches with hold periods
Engineering depth
- EDI or CSV ingest for legacy supplier catalogs with validation pipelines
- Credit limits and net-terms accounting hooks for finance sign-off
- Multi-warehouse and drop-ship routing without double-selling inventory
