Service
Multi-tenant architecture, subscription billing, roles and permissions, usage analytics and an operator console. We run Prizma360 and GoBrandIt ourselves, so the parts that get expensive in year two are the parts we design first.
The difference between a web app and a SaaS product is mostly this list.
Architecture and tenancy model
Subscription billing and plans
Roles, permissions and team accounts
Onboarding and trial flows
Usage analytics and reporting
Operator and admin console
Email, notifications and webhooks
Deployment, monitoring and backups
Shared database or isolated per tenant changes everything downstream: hosting cost, compliance answers, migration pain and how much a large customer can ask for. It is one of the few decisions that is genuinely expensive to reverse.
Billing touches signup, permissions, usage limits, dunning and support. Bolting it on at the end is where most SaaS projects lose their schedule, so we do it while the rest is still soft.
A first release that does one job properly beats a feature list nobody has tested. Real users tell you which of the next ten features actually matter, usually not the ones on the roadmap.
A product you can charge for on day one, not a demo that still needs the commercial half built.
Signup, trial, payment, upgrade, downgrade and cancellation all working end to end rather than stubbed out for later.
So your team can see tenants, fix a subscription, extend a trial and answer a support ticket without pulling a developer off the roadmap.
Signups, activation, churn and feature usage instrumented before launch, because retrofitting analytics means guessing about your first six months.
Which payment and billing providers do you use?
It depends where your customers are. For international revenue we normally use Stripe or Paddle, with Paddle worth considering because it handles sales tax and VAT as merchant of record. For customers paying inside Nepal we integrate the local gateways such as eSewa, Khalti and Fonepay. Plenty of products end up needing both, and we build for that rather than retrofitting it.
How do you handle tenant data isolation?
Most products are best served by a shared database with enforced tenant scoping at the query layer, which keeps hosting costs sane. Where a customer contract or a regulator demands it, we isolate per tenant at the schema or database level. We will walk you through the cost and operational difference before you choose, because switching later is a migration project rather than a setting.
Can you take over an existing SaaS product?
Yes, starting with a paid audit of the code, the data model and the infrastructure bill. Inherited SaaS products usually have one or two structural decisions driving most of the pain, and it is worth knowing which before committing to either a rewrite or another year of patching. You keep the audit either way.
Who pays, what they get, and what stops them leaving. That conversation shapes the architecture more than any feature list.
