A subscription idea, no model
The product lives in someone's head or as a prototype, but it's unclear how to price it, how to charge and what the first paying customer needs.

We build SaaS products from the monetization model. First we define what the customer pays monthly, then we write code.

The product is deployed by hand for every client, customizations pile up, and onboarding a new client takes weeks.
Clients keep coming, the system slows down, billing breaks on non-standard plans, and every update becomes a risk.

and answers
Technically they are similar. The difference is the business model. SaaS serves many customers on one platform, so from day one you need data isolation, plans, billing, onboarding without a manager and retention metrics. A web app can be an internal tool without any of that. If a subscription is not planned, a SaaS architecture is an unnecessary cost.
It depends on the stage. For a first test you can take payment manually and skip complex pricing. Once there are a few dozen customers, manual payment eats the team's time and hides real churn. Automated billing then pays for itself faster than it seems.
Yes, but it is usually a rebuild, not a small extension. An internal system is built for one company: a shared database, manual setup, no plans. We audit first and show what can stay and what has to be rebuilt for multi-tenancy.
Development is our scope. Sales and marketing are a separate job. We build the product so marketing has something to work with: funnel analytics, onboarding and a trial. Promotion can be added separately through the GVSPACE marketing practice.
