SaaS development services: senior teams for multi-tenant platforms

Ryz Labs provides SaaS development services through senior teams that build and scale multi-tenant software products: tenant isolation, subscriptions and usage billing, self-serve onboarding, and the SSO, SCIM and audit features enterprise buyers require. Our engineers are in the top 1% of the tens of thousands we interview, work on US business hours, and ship in your repos and cloud alongside your product team.

What we build

A SaaS product has a set of platform capabilities every customer depends on, separate from the features that make it unique. Our teams build both, and these platform pieces are where experience matters most.

• Multi-tenant architecture: pooled or siloed tenancy, chosen per data sensitivity, with tenant context enforced at the database through Postgres row-level security or separate schemas.
• Subscriptions and metered billing: Stripe Billing plans, trials, upgrades and downgrades with proration, usage metering and entitlement checks that gate features by plan.
• Enterprise readiness: SAML and OIDC single sign-on, SCIM user provisioning, custom roles, audit logs customers can export, and IP allowlists.
• Self-serve onboarding: signup, workspace creation, invitations, sample data and in-product guidance that gets new accounts to first value.
• Public APIs and webhooks: versioned REST or GraphQL APIs, API keys and OAuth apps, signed webhooks with retries, and developer docs.
• Admin and support tooling: internal consoles to look up tenants, impersonate safely with logging, adjust plans and debug customer issues.
• Single-tenant to multi-tenant migration: consolidating per-customer deployments into one platform, tenant by tenant, without downtime for existing customers.

How an engagement works

1. Talk. We review your product, architecture, tenant count and growth, the deals stuck on missing enterprise features, and your reliability record.
2. Match. We propose a team scoped to the roadmap, with names and a monthly price.
3. Join. The team works in your repos and cloud, joins standups and planning on US hours, and picks up a well-bounded piece of the platform first.
4. Grow. Add engineers for new product lines, add DevOps or QA as the platform grows, or hand components back to your team.

Week 1 is access, local setup and mapping how tenant context flows through the code: where it is enforced and where it is assumed. Month 1 typically ships a first platform improvement, such as SSO for one identity provider or plan-based feature gating. By month 3, the team owns a platform area with its own on-call rotation and service-level objectives. Pace depends on scope and your onboarding.

The stack our teams work in

How we keep a SaaS platform reliable as it grows

SaaS failure modes are shared failures: one mistake affects every customer at once. Senior SaaS engineers design for that.

• Cross-tenant data leaks. The worst SaaS incident is showing one customer another customer's data. Tenant scoping is enforced in the database, not only in application code, and automated tests assert that every endpoint rejects cross-tenant access.
• Noisy neighbors. One large tenant's import can slow everyone. Per-tenant rate limits, separate job queues for heavy workloads and quotas keep one account from degrading the rest.
• Downtime from schema changes. Migrations follow an expand-and-contract pattern, run in the background for large tables, and ship separately from the code that depends on them.
• Billing drift. Stripe webhooks arrive late, twice or out of order. Handlers are idempotent, entitlements reconcile against Stripe on a schedule, and every plan change is logged.
• Breaking integrations. Customers build on your API and webhooks. Versioning, deprecation windows and contract tests keep their integrations working while the platform changes.
• Blind spots per customer. Averages hide the one tenant having a bad day. Metrics, traces and error rates are tagged by tenant, so support can see exactly what a customer experienced before they escalate.
• Security reviews that stall deals. Our engineers have experience working within SOC 2 controls: access reviews, encryption at rest and in transit, change management and logging, so answering a customer's security questionnaire is routine.

Team shapes and cost

Typical Ryz cost is $7,000–$15,000 per engineer per month, mostly mid-level to senior: mid-level (comparable to Amazon L5) $7,000–$10,000, senior (comparable to Amazon L6) $10,000–$15,000, and leads $15,000+, quoted per team.

• Enterprise-readiness squad: 2 senior engineers on SSO, SCIM, roles and audit logs. 2 × $10,000–$15,000 = $20,000–$30,000 per month.
• Product team: a tech lead plus 4 full-stack engineers. 4 × $7,000–$15,000 = $28,000–$60,000, plus the lead at $15,000+, so about $43,000–$75,000+ per month.
• Platform team: a tech lead, 4 senior engineers and a DevOps or site reliability engineer for tenancy, scaling and reliability. 5 × $10,000–$15,000 = $50,000–$75,000, plus the lead, so $65,000+ per month.

You get a scoped plan, a price and the names of the people before you start.

Dedicated team or staff augmentation?

A dedicated development team fits a new product line, a platform rebuild or a tenancy migration that one team should own. Staff augmentation fits when your product and engineering leadership are in place and you need senior SaaS developers on your team, working from your roadmap. Many SaaS companies combine both: a platform team plus individual engineers on feature teams.

When Ryz isn't the right fit

If you want a no-code tool or a template to test demand, start there. If you need engineers on European or Asian hours or follow-the-sun support, a global network fits better. And if you need a go-to-market or pricing strategy engagement, that is consulting work, not engineering.

FAQ

How much do SaaS development services cost with Ryz?

Typical cost is $7,000–$15,000 per engineer per month, mostly mid-level to senior, with leads at $15,000+ quoted per team. Total cost is team size × duration × monthly rate: four senior engineers for 6 months is 4 × 6 × $10,000–$15,000 = $240,000–$360,000.

How fast can a SaaS team start?

After the scoping call we propose a team with named engineers. Most of the timeline depends on scope and your onboarding, including access to production-like environments.

Should we use a single database for all tenants?

Often yes, with tenant isolation enforced through row-level security. Separate databases or accounts make sense for customers with strict isolation or data residency needs. Many platforms run both models.

Can you add enterprise SSO to our existing product?

Yes. SAML and OIDC SSO, SCIM provisioning, custom roles and audit logs are some of the most common first projects for our SaaS teams.

Do you help with SOC 2?

Our engineers have experience working within SOC 2 controls and can build the technical controls your auditor will review. Ryz does not provide audits or certifications.
