Services
YuSMP Group builds multi-tenant SaaS platforms from scratch and re-platforms existing single-tenant products into modern, scalable B2B SaaS. We engineer the parts that decide whether a SaaS survives its first 1000 tenants — billing on Stripe Billing or Chargebee, strict tenant isolation, RBAC, SSO with SAML and SCIM, immutable audit logs, and region-pinned data residency across EU and US. Senior engineering teams in Cyprus and Armenia run on CET with East-Coast US overlap.
We deliver full-cycle SaaS engineering — product engineering, cloud infrastructure, billing, growth engineering, and compliance — under one accountable squad. New B2B SaaS products get a multi-tenant foundation, a billing backbone, enterprise auth, and an observability stack from week one, so the first paying customer never blocks the next ten. Re-platform engagements migrate single-tenant or legacy SaaS into a modern stack without downtime windows that customers notice. Reference work includes ANT, a PropTech SaaS marketplace; Signatory Pro, an e-Signature SaaS handling regulated documents; and BasilDoc, a HealthTech SaaS where HIPAA-capable engineering is non-negotiable.
Row-level isolation with a tenant_id on every domain table for fast-iterating B2B SaaS, or schema-per-tenant where regulators or enterprise buyers demand hard data segregation. Clean tenant offboarding with deterministic deletion is built in, not bolted on.
Stripe Billing or Chargebee for subscriptions, proration, and trials. Usage metering for consumption-based plans, automated dunning with smart retries, and invoice tax through Stripe Tax or Avalara so VAT and US sales tax are not your problem.
SSO via SAML 2.0 and OIDC tested against Okta, Azure AD, and Google Workspace. SCIM 2.0 provisioning for user and group lifecycle, RBAC with custom roles, and an immutable audit log covering authentication, configuration, and data access.
Customer data stays where the contract says it stays — EU regions for European tenants, US regions for US tenants, with workloads and backups deployed per region. Data export on demand in machine-readable formats, with a documented sub-processor list.
SLO-driven engineering with explicit error budgets, distributed tracing on OpenTelemetry, error tracking on Sentry, and dashboards on Datadog. Production incidents are diagnosed in minutes through correlated traces, logs, and metrics — not by reading customer tickets.
In-app onboarding flows, A/B testing on PostHog or LaunchDarkly, product-led growth instrumentation, and a clean event taxonomy that marketing, product, and data can all read. Activation, conversion, and retention dashboards from day one.
A one to two week deep dive into product vision, target ICP, pricing model, compliance scope, and integration surface. Output is a written architecture brief, a tenancy model decision, and a phased delivery plan.
Multi-tenant architecture, billing on Stripe Billing or Chargebee, enterprise auth with SSO and SCIM, audit logs, observability, and CI/CD on Terraform. The foundation is in place before the first product feature ships.
Feature delivery in two-week sprints against a shared backlog, with code review, automated tests, and weekly demo cadence. Releases are continuous and gated by feature flags, so paying customers see progress without surprises.
SRE on-call rotation, customer-zero migrations for risky changes, quarterly architecture reviews, and growth experiments. The same squad that built the SaaS operates it, so production knowledge does not evaporate at handover.
For scoped SaaS modules with a defined deadline — a billing migration, a compliance scope, an SSO + SCIM bundle, or a customer-zero re-platform of a single tenant.
Default model for ongoing SaaS work. Monthly invoicing per role and seniority, with full visibility on hours, capacity, and feature throughput. Predictable spend without freezing the roadmap.
A long-running SaaS product squad you treat as your own — engineers, QA, DevOps, and a delivery lead under your backlog. Best for SaaS operators scaling past their first product-market fit.
Native iOS and Android e-signature clients with a Symfony + React CRM for a cross-border law firm — KYC onboarding and a defensible evidence trail for US & EU matters.
Unified crypto-ecosystem hub aggregating multiple tokens — live exchange data, search, charts, direct purchase entry point.
Patient app for a 40-city lab network — appointment booking, digital results, 2,500+ tests, scheduling and accounting integrations.
GDPR-aligned · CCPA-acknowledged · SOC 2 Type II in progress · HIPAA-capable · PCI DSS-capable
We have shipped real B2B SaaS — ANT, Signatory Pro, BasilDoc — not just generic web apps with login screens. Tenancy, billing, SSO, and observability are decisions we have already made many times, so your foundation is rehearsed.
GDPR-aligned engineering with EU data residency, CCPA-acknowledged for US consumer data, SOC 2 Type II in progress, HIPAA-capable for PHI workloads, and PCI DSS-capable scoping for payment flows. Audit-ready from the start.
Senior engineering teams in Limassol and Yerevan deliver on a CET workday with a guaranteed 9 AM–1 PM ET overlap for daily standups, code reviews, and incident response. EU offices get up to seven hours of synchronous time.
For payments-adjacent SaaS we run inside PCI DSS scope and align directly with your QSA on access, logging, and segregation of duties. For HealthTech SaaS we sign BAAs at the infrastructure layer and isolate PHI workloads from analytics pipelines.
Yes. We design the multi-tenancy model on day one — typically row-level isolation with a tenant_id column on every domain table for new B2B SaaS, or schema-per-tenant for products with strict data-segregation requirements. We layer in tenant provisioning, clean tenant offboarding with deterministic data deletion, per-tenant feature flags, a billing backbone, an admin console, and SSO/RBAC scaffolding. Most greenfield SaaS MVPs ship a paying-customer-ready v1 in 12–16 weeks.
Often. We start with a tenancy audit of the existing codebase and database, then plan the migration in phases: introduce tenant_id, dual-write or backfill data, gate access at the ORM and API layers, refactor background jobs, and finally retire the legacy single-tenant deployment per customer. We run customer-zero migrations on a dark-launched copy of production so the first real tenant cuts over with measurable risk, not a leap of faith.
Enterprise readiness is a concrete checklist: SAML 2.0 and OIDC SSO with at least Okta, Azure AD, and Google Workspace tested; SCIM 2.0 user and group provisioning; role-based access control with at least three default roles plus custom roles; an immutable audit log covering authentication, configuration, and data access; data export on demand in a machine-readable format; and a clearly documented sub-processor list. We ship those capabilities as part of the platform foundation, not as a paid add-on.
We integrate Stripe Billing or Chargebee for subscription lifecycle, proration, usage-based metering, and invoice generation. Tax is handled through Stripe Tax or Avalara so you do not maintain VAT and sales-tax tables yourself. Dunning is automated with smart retries, email and in-app reminders, and a clear grace-period policy that does not break paying customers. Revenue recognition is exported to your finance stack — typically NetSuite, QuickBooks, or Xero — through scheduled jobs or a thin reconciliation service.
We build with compliance in mind from the foundation phase. GDPR-aligned engineering covers lawful basis, data residency, DSARs, and sub-processor transparency. We are SOC 2 Type II in progress and aligned to the trust services criteria for security and availability, which directly maps to your own SOC 2 scope. HIPAA-capable delivery is available for PHI workloads with BAAs at the infrastructure layer. CCPA notice obligations and PCI DSS scoping for payment flows are addressed when the SaaS handles US consumer or cardholder data.
Yes. After launch the same squad transitions into a run mode with SLO-driven SRE, error budgets, an on-call rotation, and a defined incident response process with public status communication. Observability is built on Datadog, Sentry, and OpenTelemetry instrumentation we install during the build phase, so production issues are diagnosed in minutes not hours. We also run growth experiments, customer-zero migrations for new features, and quarterly architecture reviews to keep the platform healthy past 1000 tenants.
