Full WordPress Apps, Built and Ready to License

Beyond custom websites, SITSS builds complete WordPress/WooCommerce management applications — for schools, laundry chains, homestay operators and retail teams — and hosts them from our own app licensing platform at sitss.in.

Every app ships as an installable WordPress plugin, each with its own dedicated page below showing full details, a Free direct download and a Free-vs-Premium comparison. Upgrade to Premium whenever you’re ready, purchased instantly with a real license key and automatic version updates. Need something none of these cover? We build custom plugins to spec too.

FAQ

Questions About Our WordPress Apps

How is this different from a custom website?

These are complete, ready-built management applications you install as a WordPress plugin on your own site — not a website build from scratch. You get working software on day one, licensed and updated by us.

Can I try before I buy?

Yes — every app has a Free tier you can download directly from its own app page (see each app above) and install on your own site, with real core functionality, before deciding whether to upgrade to Premium.

What happens if my license expires?

You get a grace period to renew; if it lapses beyond that, the plugin automatically reverts to its Free tier rather than breaking your site.

Can you build something not listed here?

Yes — we regularly build custom WordPress/WooCommerce apps to a client’s exact workflow and can license and host them the same way.
