Built here. Ready to try.

Good software makes
the work feel lighter.

Two everyday business problems, turned into working tools. Open a demo and take it for a spin. All projects and prices are illustrative.

These two demos are not screenshots or mockups. They are working software built the same way 0ARCH builds for a paying client: real forms, saved state, validation, and output you can actually use. The client workspace shows what a customer sees once a project starts: status updates, file approvals, and a message thread, the same pattern used in the client portals this site builds for service businesses. The estimate builder shows a trade tool: enter room dimensions and your rates, and it does the math and prints a clean, itemized estimate ready to hand to a customer on the spot. Try either one end to end, click around, change the numbers. Nothing you type is saved on a server or sent anywhere; it stays in your browser until you close the tab.

If one of these looks like what your business needs, the real version starts the same way every 0ARCH project does: a short call to describe the workflow you want to replace, then a written estimate scoped to the exact screens and data your team uses every day, not a kit with features you will never touch. Most client portals and estimate tools like these take a few weeks to build and launch. See finished examples on the work page, or get in touch to talk about what your team needs.
