The brief
Multi Tenant SaaS Development & Subscription Platform Engineering
We build production grade, multi tenant SaaS applications end to end, with secure authentication, subscription billing, role based access, analytics dashboards and admin tooling, architected on a modern stack so you can onboard customers, charge them, and scale without replatforming.
Without it
- Auth, billing and tenancy are eating the time meant for your core feature.
- Your MVP can’t support separate customers, roles or plans.
- Enterprise prospects ask for SSO and audit logs you don’t have.
With Caudify
- Multi tenant foundations that scale without replatforming.
- Subscriptions, trials and invoicing handled end to end with Stripe.
- The admin, analytics and enterprise features buyers expect.

Questions
SaaS development questions, answered.
- Q1Shared database or a database per tenant?
- Most SaaS products start with a shared database and strict tenant isolation, which is cost effective and simple to operate. We design so large or regulated customers can be isolated further later.
- Q2Can you support usage based pricing?
- Yes. We meter usage in the product and sync it to Stripe, supporting seats, usage, tiers or hybrid pricing models.
- Q3Do you build the marketing site too?
- We can, or we hand over a clean integration for sign up, trials and pricing pages if your marketing team runs the site.
