Modular commerce
operating system.
VenduStack is the engine underneath every VenduSys surface — APIs, orchestration, identity, ledgers and AI exposed as composable primitives. Build any channel without re-inventing the core.
Six primitives.
Every commerce surface.
The core does not assume what you are selling, who you are selling to, or how value moves between parties. It assumes the structure underneath is the same.
Headless, composable APIs
GraphQL and REST surfaces over every primitive — products, accounts, orders, ledgers, policies. Build any channel without re-inventing the core.
Workflow engine
Model the real flow of value — listings, approvals, payouts, returns, renewals — as code or visual graphs. Branch, retry, observe.
Unified accounts & trust
One identity graph across buyers, sellers, operators and partners. KYB/KYC, roles and audit trails — built in, not bolted on.
Payments & ledgers
Multi-party payments, escrow, split payouts, subscriptions and refunds — all reconciled against a transparent, auditable ledger.
Built-in analytics & AI
Pricing, ranking, fraud and recommendation models that ride your data — with auditable decisions and a clear opt-out path.
Integrations & extension
Native connectors for ERP, CRM, IAM, payments and logistics. Extend with TypeScript, deploy at the edge — zero lock-in to a runtime.
Inside the core.
VenduStack is composed of small, named services with explicit contracts. Each can be adopted, replaced or extended independently.
Four entities.
Everything else derives.
Most commerce platforms accrete dozens of entities until the model breaks. VenduStack keeps the core flat — four root types, with everything else as a relationship or projection on top.
Party
A person, organization or agent. Buyers, sellers, operators and partners are projections of the same underlying record.
Thing
Anything offered or owned: products, licenses, services, subscriptions, assets, time. Variants and bundles ride on top.
Move
An event that shifts value or rights between parties. Orders, returns, renewals, transfers and disputes are all moves.
Entry
A line in the ledger. The model is designed so every Move produces Entries, with reports and balances derived from them.
Built to run.
Performance numbers from our load test bench. Indicative, not guaranteed — we will publish the methodology with v1.0.
p50 under 28 ms
API surface, EU region. p99 under 120 ms across the catalog read path.
50k req/s
Sustained on a single tenant cluster. Auto-scales horizontally.
10k flows/s
Concurrent orchestration runs with at-least-once delivery and replay.
RPO 0 · RTO 5 min
Cross-region failover for ledger and identity stores.
Speaks to everything already running your business.
VenduSys assumes you have systems. Native, first-class connectors live alongside an open webhook + REST surface, so you can wire in whatever else you run.
A platform is not features.
It is the shape of the primitives.
Open
Open APIs, open identity, open data exits. Your data is yours — VenduSys just keeps it coherent.
Auditable
Every decision, every workflow step, every ledger entry is observable and replayable.
Composable
Adopt one primitive or the whole stack. Replace any piece. No runtime lock-in.
EU-native
Hosted in the EU. GDPR, DPA and data-residency are first-class — not retrofits.
