SaaS Development Company in San Antonio

Honest ranges, because a SaaS budget is really three budgets. A functional MVP with real multi-tenancy, authentication with SSO, a core workflow, basic billing and a deployable pipeline typically runs USD 70,000 to 180,000 over three to five months. That number goes up quickly if you need enterprise SSO with SCIM, an audit log that satisfies a security review, or a second persona in the product. A production-grade platform with several modules, role-based permissions, integrations into customer systems, metered billing, an admin console and observability typically runs USD 200,000 to 550,000 across phases. Compliance is a separate line: SOC 2 Type II readiness engineering, meaning the logging, access review, change management and evidence collection work rather than the audit fee, generally adds USD 40,000 to 120,000, and a TX-RAMP or FedRAMP path adds substantially more depending on level. San Antonio rates run roughly 30 to 45 percent below San Francisco and New York at equivalent seniority and below Austin as well. Ongoing engineering after launch is typically a monthly retainer sized to your roadmap. We quote fixed fee against a signed statement of work so the number does not move mid-build.

TX-RAMP is the Texas Risk and Authorization Management Program, created by Senate Bill 475 in the 87th Legislature and administered by the Texas Department of Information Resources. Texas Government Code 2054.0593 requires that state agencies and public institutions of higher education only enter or renew contracts for cloud computing services that comply with TX-RAMP requirements. Level 2 certification has been required for contracts entered or renewed on or after January 1 2022, and Level 1 since January 1 2024. Level is driven by data classification and the impact of a compromise, so a product handling confidential state data lands higher than a low-impact tool. You need it if you intend to sell to a Texas state agency or a public university such as UT San Antonio, or to public community colleges like the Alamo Colleges District. You do not need it to sell to the City of San Antonio, Bexar County, a hospital system or a private company, though those buyers will run their own vendor reviews. If you already hold FedRAMP or StateRAMP authorization there is a recognized path that reduces duplicated work. We build the control set into the product from the start, because retrofitting logging, encryption and access review after the fact is the expensive version.

SOC 2 Type II is an audit of whether your controls operated effectively over a period, usually three to twelve months, which means the thing that kills startups is not the controls themselves but the absence of evidence for the months already gone. So we build the evidence generators first. Every production access is logged with actor, resource and reason, and access reviews are exportable rather than reconstructed from Slack. Change management runs through pull requests with required review, and the CI pipeline records who approved what and when, which satisfies the change control criteria without a separate process. Infrastructure is defined as code so configuration drift is visible, and secrets live in a managed vault with rotation rather than in environment files. Backups are automated and restore tests are scheduled and logged, because auditors ask for the restore test, not the backup. Vulnerability management runs continuously through dependency scanning and SAST in CI with a documented remediation SLA. Onboarding and offboarding checklists are wired into your identity provider. We do not sell the audit and we do not pretend to be your auditor. We build the system so that when your chosen firm starts fieldwork, the evidence is already sitting in tools they recognize.

The choice is driven by your customer list, not by engineering preference. Pooled tenancy, where all tenants share database and compute with a tenant identifier on every row and Postgres row-level security enforcing isolation, gives the best unit economics and the simplest operations, and it is right for most products selling to small and mid-market customers. Bridge tenancy, meaning shared compute but a schema or database per tenant, is the sensible middle when a handful of enterprise customers demand separable data and independent backup and restore, which comes up constantly with USAA-scale or hospital-system buyers. Siloed tenancy, a full stack per tenant, is expensive and slows every release, and we only recommend it when a contract genuinely requires it, which in San Antonio usually means a defense customer with CUI obligations or a federal deployment in Azure Government or AWS GovCloud. The mistake we see most often is a startup building siloed because it feels safer, then discovering at thirty customers that every release takes a week. We design the data layer so a specific tenant can be promoted from pooled to isolated later without rewriting the application, which keeps the expensive option available without paying for it on day one.

Billing is the part of a SaaS product that founders postpone and then pay for twice. The first rule is to separate three concerns that get conflated: metering, which records what happened; entitlement, which decides what a tenant is allowed to do right now; and invoicing, which turns records into money. Metering should be an append-only event stream with idempotency keys, because you will need to recompute a customer's usage after a dispute and you cannot do that from a counter. Entitlement should be a fast lookup the application checks synchronously, cached, and it should degrade to the previous known plan rather than blocking your customer if the billing service is unreachable. Invoicing belongs to Stripe or a purpose-built platform such as Orb or Metronome once your pricing has tiers, overages, credits and annual commitments, because hand-rolled proration is where teams lose weeks. Design for the pricing changes you know are coming: a plan is data, not a code branch. And instrument the metering pipeline with reconciliation jobs that compare what you metered against what you invoiced, running daily, because silent revenue leakage is invisible until an annual true-up finds it. Enterprise contracts here often want purchase orders and net terms, so support invoicing outside self-serve checkout.

The Texas Data Privacy and Security Act took effect July 1 2024, and unlike California's law it does not use revenue or record thresholds, so it reaches most SaaS companies doing business in Texas that are not genuine small businesses. If your customers are the controllers and you process on their behalf, the statute requires a written contract governing that processing which sets out the nature and purpose, the types of data, the duration, the duties of both parties, a confidentiality obligation on your personnel, deletion or return of data at the end of the relationship, and a duty to make available the information needed for the controller to demonstrate compliance. You also need controller permission for subprocessors and a flow-down of the same obligations, which means your list of subprocessors has to be published and versioned rather than buried. Operationally that translates into concrete product work: per-tenant data export in a usable format, a real deletion path that reaches backups and caches on a documented schedule, honoring universal opt-out signals where you serve end consumers, and consent gating for sensitive categories such as precise geolocation, biometrics and health data. The Texas Attorney General enforces exclusively with a cure period, and the office has pursued large privacy matters aggressively.
