A focused SaaS MVP with core workflow, billing, and authentication takes 10–16 weeks. A mid-complexity SaaS product with multi-tenancy, SSO, AI features, and mobile takes 5–8 months. A full-featured enterprise SaaS product with compliance infrastructure and comprehensive AI capabilities takes 8–14 months. The biggest variable is the complexity of the enterprise feature set SOC 2 preparation, SCIM provisioning, and granular RBAC are each significant engineering projects in their own right and their timing in the roadmap depends on when the enterprise sales motion starts requiring them.

Multi-tenancy in SaaS means that a single deployment of the software serves multiple customer organisations tenants with their data isolated from each other. There are three main approaches: separate database per tenant (strongest isolation, highest infrastructure cost, best for regulated industries), separate schema per tenant within a shared database (good isolation, moderate cost, reasonable scale), and shared database with row-level tenant identification (lowest cost, requires careful application-level enforcement, most common). The choice depends on the product's compliance requirements, the expected tenant count, and the customer type. Getting multi-tenancy wrong creates cross-tenant data exposure risks that are difficult and expensive to fix after customers are onboarded. We address the multi-tenancy architecture in the product discovery phase before the first line of code is written.

Enterprise readiness for a SaaS product typically means: SSO integration with enterprise identity providers (SAML 2.0, OIDC) via Okta, Azure AD, or Google Workspace; SCIM automated user provisioning and deprovisioning; granular role-based access control with custom role creation; SOC 2 Type II compliance report; penetration testing with a clean or addressed report; data processing agreement and GDPR compliance documentation; SLA commitments with uptime history; dedicated support channel or CSM; and an API that enterprise IT teams can integrate with. Most enterprise procurement processes include a security questionnaire that covers all of these areas. SaaS products that were not designed for enterprise readiness typically spend three to six months on remediation work for each enterprise deal they are trying to close.

SaaS billing starts with a simple monthly flat rate per seat and gets complex quickly. Usage-based metering for products where value is proportional to consumption. Per-seat billing with minimum commitments for enterprise contracts. Multi-product bundles with cross-product discounting. Annual contracts with monthly payment and proration for mid-term upgrades. Custom enterprise pricing that does not fit any standard tier. We build billing infrastructure on Stripe Billing or Chargebee that is designed for the pricing model the product has today and the pricing models it is likely to need in the next two to three years because retrofitting billing infrastructure to support a new pricing model when the sales team has already committed to it is an expensive and disruptive engineering project.

AI-integrated SaaS product development means building products where AI capabilities are core to the value proposition, not demo features. In B2B SaaS this includes workflow automation using LLMs that completes multi-step tasks on behalf of users, semantic and natural language search that surfaces product data through conversational queries, predictive analytics that surface insights proactively rather than through manual report generation, customer health scoring that predicts churn risk before it reaches the CSM's radar, AI-assisted onboarding that personalises the setup path for each customer, and in-product AI copilots that make complex functionality accessible through natural language. These capabilities require event tracking infrastructure, feature store design, and model serving architecture built from the first active user, which is why we address AI architecture strategy in the product discovery phase.

SOC 2 compliance for a SaaS product is an architecture and engineering project, not a documentation project. The Trust Service Criteria security, availability, processing integrity, confidentiality, and privacy, each have specific technical controls that need to be implemented and maintained. The audit evidence collection is a continuous operational process, not a quarterly effort before each audit. We approach SOC 2 preparation by designing the compliance controls into the product architecture from the start: immutable audit logging on user actions and data access, access control reviews, incident response procedures, change management processes, and the automated evidence collection that makes the SOC 2 audit a reporting exercise. For products pursuing SOC 2 Type II, we work with the client's chosen auditor to ensure the control design meets the auditor's evidence requirements.

Three models: Dedicated SaaS Product Team for multi-quarter product builds and ongoing product evolution; Time and Material for iterative development where the product direction is evolving based on customer feedback which is most SaaS products, most of the time; and Fixed Cost for well-defined SaaS product builds where the architecture decisions, feature scope, and compliance requirements are clearly documented before development begins. We recommend the right model based on how complete the product and architecture design is at the start of the engagement.
