The first is whether it works for the first paying customers, and the second is whether it survives an enterprise buyer's procurement process a year or two later. A saas development company serving US businesses has to design the multi-tenant architecture, billing model and authentication layer with both timelines in view, since adding SOC 2-aligned access controls or SSO to a product built without them costs far more than including them from the start. The other US-specific constraint that catches founders off guard is sales tax. Since the 2018 South Dakota v. Wayfair decision, states can require a SaaS vendor to collect sales tax based on economic nexus (revenue or transaction volume in that state) rather than physical presence, and several states tax SaaS subscriptions as a taxable service. That has to be handled through the billing system, not bolted on after the first state notice arrives. Market ## What the USA buyers expect from this work - ### SOC 2 readiness as a sales requirement, not a nice-to-have Once a SaaS product starts selling to mid-market or enterprise buyers, a SOC 2 report (or at minimum a security questionnaire response backed by real controls) becomes a deal-blocking requirement. We architect access controls, audit logging and encrypted secrets from the first release so the product is ready for that conversation when it comes, rather than needing a re-architecture to pass it. - ### SSO and SCIM for enterprise buyers Enterprise IT teams expect to provision and deprovision users through their own identity provider (Okta, Azure AD, Google Workspace) via SAML or OIDC single sign-on, and increasingly expect SCIM for automated user lifecycle management. Building this as an add-on tier rather than the default auth path is the more common and more costly mistake. - ### Sales tax on subscription revenue SaaS is a taxable service in a growing number of US states, and economic nexus rules mean a company can owe sales tax in a state where it has no office simply by crossing a revenue or transaction threshold there. We integrate the billing system with Stripe Tax or Avalara so tax is calculated and remitted per state automatically rather than tracked in a spreadsheet. - ### Usage-based and seat-based billing US B2B buyers increasingly expect a mix of seat-based and usage-based pricing rather than a single flat tier, which means the billing system needs to meter usage accurately (API calls, active seats, storage) and reconcile it against Stripe subscriptions without manual invoice adjustments each month. ## Compliance we plan for - SOC 2-aligned access controls, logging and encryption from the first release - CCPA/CPRA and state privacy law for customer and end-user data - Sales tax nexus and remittance across states via Stripe Tax or Avalara - HIPAA where the SaaS product handles protected health information ## How the engagement runs Early-stage SaaS work usually starts as a fixed-scope MVP build, validating the core workflow with a small set of design partners before expanding scope. Once the product has paying customers, engagement typically shifts to an ongoing sprint-based arrangement covering new features, SSO/SCIM support and the security work enterprise deals require. IP assigns to the client on payment, the codebase lives in the client's own repository, and infrastructure (AWS, GCP or a comparable provider) runs under the client's own account rather than ours, so there's no dependency on us to keep the product running.

Not always before the first enterprise deal, but you need the underlying controls in place, access logging, encrypted secrets, a documented incident response process, since most enterprise security questionnaires ask about them directly. A formal SOC 2 Type II report usually follows once enterprise revenue justifies the audit cost. How do you add SSO for customers using Okta or Azure AD? We build SAML and OIDC support into the authentication layer as the standard login path, not a separate enterprise-only fork of the app, so adding a new identity provider is a configuration step rather than a code change each time an enterprise customer asks for it. Does our SaaS product need to charge sales tax? In a growing number of states, yes, SaaS subscriptions are taxed as a service, and economic nexus rules mean you can owe tax in a state based on revenue there alone, without any physical presence. We integrate Stripe Tax or Avalara into billing so this is calculated automatically rather than tracked manually. Can you build both seat-based and usage-based pricing into our billing? Yes. We meter the relevant usage (API calls, active seats, storage, depending on the product) and reconcile it against Stripe subscriptions so invoices reflect actual usage without a manual adjustment step each billing cycle. How do you handle multi-tenancy for a B2B SaaS product? Most projects use a shared database with strict tenant isolation at the query layer, which scales well for typical B2B usage patterns and keeps infrastructure cost reasonable; a small number of customers with strict data-residency or compliance needs get a dedicated database instead. Who owns our AWS or GCP infrastructure once the build is done? You do. Infrastructure runs under your own cloud account from the start, configured through code we hand over along with the repository, so there's no dependency on our systems to keep the product running after the engagement ends.
