What is Multi-Tenant SaaS?
Multi-tenant SaaS is a software architecture where one installation of an application serves many separate customers ("tenants"), each seeing only their own data, branding and users. Rather than installing a fresh copy per client, the provider runs a single system in which tenant A's events, menus or subscribers are logically walled off from tenant B's, usually by a tenant ID on every database record.
This is the economics behind affordable Indian SaaS: one server and one codebase can serve 500 event organisers or restaurants, so each pays a few hundred rupees monthly instead of lakhs for custom software. Upgrades reach everyone at once. For resellers it enables white-labelling — an agency can offer the platform under its own brand, with each of its clients as a tenant beneath it.
