SaaS that scales.
Multi-tenant architecture, metered billing, real-time sync and edge deployment — the hard parts of SaaS, handled, so thousands of organizations run reliably on one codebase.
The hard parts, handled.
Multi-tenant by design
Row-level isolation, per-tenant config and dynamic schema routing — secure separation without running a thousand databases.
Metered billing & plans
Stripe subscriptions, usage metering, trials and upgrades baked in.
Roles & permissions
Org-level RBAC, SSO and audit trails your enterprise buyers expect.
Fast everywhere, in sync everywhere
Edge-first deployment for sub-50ms responses and real-time collaboration via WebSockets and optimistic state.
Built to enterprise spec.
| Capability | Typical build | HSMCVN build |
|---|---|---|
| Tenancy | Shared, leaky | Row-level isolated |
| Concurrency | 1k–5k users | 500k+ elastic |
| Latency (P99) | 200–400ms | < 85ms global |
| Billing | Bolted on later | Native, metered |
| Deployment | Manual / weekly | GitOps / instant |
Meet Stable Invoicing.
Invoicing & quotes, done properly.
A fast desktop app for small businesses to send clean invoices and quotes, track what's outstanding, and get paid — no monthly subscription, your data stays on your machine.
- Dual taxes (GST/PST) with per-line control
- PO numbers, GST number and custom payment terms
- Quotes that convert to invoices in one click
- Client & saved-item library, multi-currency totals
- Dashboard for outstanding, overdue and income
Off-the-shelf invoicing tools are subscriptions that hold your data hostage. Stable Invoicing is a one-time desktop app — the kind of focused product we build for clients who want to own their software, not rent it.
