SaaS Product Development

For founders building subscription products, internal SaaS tools, or vertical software businesses. The goal is to turn a business workflow into a multi-user software product with auth, billing, roles, onboarding, and retention loops. The work is practical: product shape, database, auth, payments, mobile, SEO, and deployment all have to fit together.

Questions before starting

+Can you help decide what to build first?

Yes. The first version should prove a business workflow and payment path, not just a UI concept. Harman can help scope the build around the smallest useful paid product.

+Can billing and subscriptions be included?

Yes. Stripe subscriptions, invoices, payment links, customer portals, and entitlement checks can be included in the product architecture.

+Do you build admin tooling?

Yes. Admin dashboards, CRM views, support tools, analytics, and internal operations pages are often part of the first serious SaaS build.
