Create your account and workspace
1. Sign up
Go to mastocontrol.com/signup and create an account with your email and password. Every plan includes a 14-day free trial — no card required.
After registering, check your inbox: Masto Control sends a verification email. Click the link to confirm your address before you can log in.
2. Create your workspace
A workspace (also called a tenant) is your company's isolated copy of Masto Control — its own database, its own users, its own data. To create one:
- Company name — shown across the app and on invoices.
- Workspace address (slug) — used in the part of the URL that identifies your workspace. Use lowercase letters, numbers, and hyphens only.
- Interface language — the default language for everyone in this workspace (see Interface language — it can be changed later, per user).
Workspace creation prepares an isolated database for your company, which usually takes 10–30 seconds.
3. You're in
Once the workspace is ready, you land in the app at https://app.mastocontrol.com, logged in as the workspace's first user — automatically an Admin with full access.
From here, follow How to start for a full walkthrough — from setting up warehouses and dictionaries to your first recorded sale and inviting your team.
Only one session per account can be active at a time. Logging in on a new device signs you out everywhere else within about 15 seconds, with a message explaining why on the login screen.
Protect the account
Once you are in, consider adding two-factor authentication: a code from an authenticator app on top of your password, set up from the same account page.
