# OIO > OIO (oio.app) is project management for client work, built for small creative > studios (3D, motion, animation) and freelancers. One page per client project > with tickets, timeline, files, team chat, recorded calls and budget, plus the > inquiry form, prospects, proposals, contracts with client e-signing and > invoices around it, behind one login. The invoice knows its project and the ticket knows its client: marking an invoice paid updates that project's budget. OIO does not process or detect payments; the user marks an invoice paid. ## Key pages - [Home](https://oio.app/): what OIO does, with product film and screenshots - [For studios](https://oio.app/studios): small studios working with remote freelancers - [For freelancers](https://oio.app/freelancers) - [Pricing](https://oio.app/pricing) - [Comparisons](https://oio.app/vs): OIO against other project and client tools, including [ShotGrid](https://oio.app/vs/shotgrid), [ftrack](https://oio.app/vs/ftrack), [Kitsu](https://oio.app/vs/kitsu), [Productive](https://oio.app/vs/productive) and [Teamwork](https://oio.app/vs/teamwork) - [Free tools](https://oio.app/tools): invoice and quote generators, rate calculators, late payment tools, PDF, image and video tools that run in the browser, no signup - [Templates](https://oio.app/templates): invoice, quote and contract templates - [Guides](https://oio.app/guides): articles on invoicing, quotes, contracts and project budgets - [About](https://oio.app/about), [Security](https://oio.app/security), [Terms](https://oio.app/terms), [Privacy](https://oio.app/privacy), [Imprint](https://oio.app/imprint) ## Free tools (no account, run in the browser) - [Free invoice generator](https://oio.app/tools/invoice-generator): fill in a form, see the invoice build live, download a PDF.
