State sales tax on SaaS
Whether SaaS is taxable depends on the state, and rules differ on what counts. We connect billing to tools such as Stripe Tax or Avalara so tax is calculated per customer location.

SaaS development company for US founders and B2B teams
InnoFeature Labs builds multi-tenant SaaS products for US startups and B2B companies: from an MVP that proves people will pay, to a platform ready for enterprise security reviews.
US SaaS has its own checklist: sales tax that changes by state, SOC 2 questions from buyers, state privacy laws and, in healthcare, HIPAA. We design for these early, when they are cheap to get right.
- Tenant isolation tested
- Stripe billing and sales tax
- SOC 2-ready logging and access
- CCPA privacy notice and requests
- HIPAA safeguards if health data
- SSO for enterprise customers

In short: We are a SaaS development company working with US founders and B2B businesses. We build multi-tenant subscription products with Stripe billing and automated state sales tax, the security controls SOC 2 audits look for, CCPA-aware data handling, HIPAA safeguards for health products, and integrations with tools such as Salesforce, HubSpot and QuickBooks.
US
What a US SaaS product has to get right
The questions US buyers ask in procurement are predictable. Building the answers in early saves months later.
SOC 2 readiness
Enterprise buyers often ask for a SOC 2 report. We build the technical controls auditors look for: access control, audit logs, change management, backups and monitoring.
State privacy laws
CCPA/CPRA in California and similar laws in other states require privacy notices, data access and deletion requests, and limits on selling or sharing data.
HIPAA for health SaaS
Health products handling protected health information need encryption, audit trails, minimum-necessary access and cloud providers that sign a Business Associate Agreement.
US payments
Cards and Apple Pay through Stripe, ACH debits and invoicing for B2B accounts, and usage-based or per-seat pricing.
US integrations
Salesforce, HubSpot, QuickBooks, Slack and Google Workspace connections that US customers expect at sign-up.

Frequently asked questions
FAQs
Do you build SaaS for US companies?
Yes. We work with US founders and B2B companies. Discovery, sprint reviews and support run online, scheduled to overlap with US business hours.
How much does SaaS development cost in the US?
It depends on features, user roles, billing model, integrations and compliance needs. We define an MVP in discovery and estimate it in USD before development starts.
Can you make our SaaS SOC 2 ready?
We build the technical controls a SOC 2 audit examines and help you collect evidence. The SOC 2 report itself is issued to your company by an independent CPA firm.
How do you handle sales tax for SaaS?
We connect billing to a sales tax engine such as Stripe Tax or Avalara, which calculates tax by customer location. Your tax adviser should confirm where you need to register and collect.
Can you build a HIPAA-compliant SaaS?
We build health SaaS with HIPAA safeguards and host it with providers that sign a Business Associate Agreement. Full compliance also depends on your policies and training, so we work alongside your compliance lead.
Who owns the code?
For custom builds the deliverables become your property after full payment unless agreed otherwise in writing.
