SaaS and web platforms
A platform connects two populations. Everything else about its design follows from that sentence.
A platform is not a large website. It is a product serving at least two groups with different interests — buyers and sellers, patients and clinicians, landlords and tenants, schools and parents — whose value depends on how many participants each side has.
That imposes a constraint projects routinely underestimate: the cold start. An empty marketplace is useless to buyers and sellers alike. The design must therefore explain how the first side gets value before the second exists, or the best-built platform stays deserted.
SaaS adds another dimension: several customer companies live inside the same software and must never see each other. Data isolation, recurring billing, subscription tiers and the ability to change one customer without breaking the others are architectural decisions taken at the very beginning. They are not added later.
What is included
Multi-tenant architecture
Each customer company isolated in its own data, with its users, settings and branding. The partition is designed on day one; breaching it afterwards is a rewrite.
Accounts, roles and permissions
Signup, invitations, teams, access levels, suspension. The most underestimated part of a platform, and the one that produces the most security incidents.
Subscriptions and billing
Tiers, trials, recurring charges, dunning on failed payments, automatic invoices. Recurring revenue needs reliable machinery, not a spreadsheet.
Back office
Your own screen: track signups, moderate, unblock a customer, see who uses what. Without one, every support request becomes an engineering task.
API and integrations
A documented interface so your customers and partners can connect their own tools. Often the thing that turns software into a platform.
Scale and operations
Monitoring, backups, logs, alerting and zero-downtime updates. A platform down for an hour loses customers it does not get back.
Who it is for
- Founders launching a marketplace or online service
- Companies whose internal tool could be sold to others
- Networks and franchises needing one system across sites
- Institutions managing members, cases or enrolments
What drives the price
- How many populations are served: a two-sided platform costs more than twice a one-way tool.
- Recurring billing and its edge cases — trials, tier changes, failed charges, refunds.
- The isolation level required, which depends on your sector and obligations.
- Expected volume, which determines infrastructure from the design stage.
- Whether there is a public API and documentation.
Frequently asked questions
How do you launch a platform with no users?
By making one side useful on its own. A management tool that serves the seller even with no buyer, a directory that serves the visitor even with no signups: build that one-way value first, then open the matching. That is how most marketplaces actually started.
Must everything be built before launch?
No. A narrow first version in the hands of real users teaches in a month what six months of meetings will not. The danger with a platform is building at length for demand you have assumed.
How is customer data isolated?
By a separation enforced at the data layer and checked on every query, not by a condition added in the interface. This is the question to put to any SaaS supplier: the answer separates a considered architecture from a site hastily adapted.
Can you handle recurring payments across borders?
Yes, but the mechanics depend on your legal entity, the currency and your customers’ countries. It belongs in scoping, because it shapes the corporate structure as much as the technical one — and it has blocked projects that discovered it too late.
