Register

Last updated: 31 July 2026

Registration creates two things in sequence: your personal user account, then the company workspace that account owns. The same page also handles the other way in - accepting an invitation to join a company that already exists on OSOSS.

The two steps

You start with Name, Email, Mobile and Password, plus the checkbox agreeing to the OSOSS terms and conditions. The Sign up button stays inert until that box is ticked. The mobile field guesses your country from your connection, and you can search the country list rather than scrolling it; the dial code itself is fixed by the country you pick. An invisible reCAPTCHA check runs on submit, and any field the server rejects - an email already registered, for example - shows its reason directly beneath itself.

Once the account exists, OSOSS takes you to the company step:

Field	Notes
Username	Becomes your subdomain, shown next to the fixed `.ososs.com` suffix. Latin letters, digits and dashes only - no spaces.
Company name	What prints on documents. Change it later in Company settings.
Work field	Your line of business. It shapes the defaults you get.
Country	Pre-filled from your connection.
Currency	Pre-filled to match the country.

Click Continue and the workspace is created with its chart of accounts, first branch and default settings, and you land in the dashboard. A Log out link sits on this page in case you signed up on the wrong account.

Joining an existing company by invitation

An invitation email carries a personal link. Opening it signs out whatever session your browser held, then checks the invitation and adapts:

No OSOSS account on that email - you get the registration form with the email filled in and locked, and the heading names the company inviting you. Completing it joins you to that company directly, with no company step.
You already have an account - you get a short sign-in form instead. Enter your password to accept and join.

The email on the invitation is the one that must sign in. Using a different address is refused, and an invitation that has already been accepted, or been withdrawn, reports itself as unavailable.

Tip: Register with a real business email you control long-term, not a personal one. It becomes the recovery address for the whole workspace, and moving it later means an admin change rather than a self-service edit.

Note: The company subdomain is your permanent web address for the account. Choose the trading name, short and without abbreviations you will regret.

Warning: Do not create a second workspace for a business that already has one on OSOSS. Two workspaces means two chart of accounts, two inventories and no consolidated reporting. Ask an existing admin to invite you from Users instead.

Verify User - confirming your account details
Company - the profile, logo and tax details that print on documents
Opening Entry - carry an existing business's balances in before you start selling
