What is Ceretta App?

Ceretta App is an operations platform for businesses that rent equipment, sell products, or run a repair shop — or any combination of the three. Rental yards, tool shops and repair centers run their whole day from a single dashboard that works on a desktop at the counter and on a phone in the yard.

Everything below happens inside one company account. Your data is isolated from every other company on the platform.

The three modules

Ceretta App is split into three modules. Your company only turns on the ones it needs — the others stay hidden from the menu entirely, so staff never see screens that don't apply to them.

Two things are always available regardless of which modules you use:

• Inventory — the catalogue underneath all three modules. It holds both the things you rent out and the things you sell.
• Payments — a single ledger covering rentals, sales and repairs together.

If a module is switched off for your company, its pages disappear from the navigation and the system refuses to accept its records. To turn a module on or off, contact your reseller or account manager.

Finding your way around

The left-hand navigation follows the flow of a normal working day:

• Dashboard — active rentals, pending and overdue payments, stock that needs reordering
• Inventory and Categories — what you own and how it's classified
• Customers — one shared customer book across all three modules
• Rentals, Sales, Service Orders — the operational screens for each module
• Payments and Cashier — money in and money out
• Preparation — the queue for staff who clean and check equipment between rentals
• Settings and Users — configuration and who can do what

Your first fifteen minutes

If you are setting up a brand-new company, do it in this order. Each step depends on the one before it.

1. Create your categories first. A category defines what kind of thing an item is, which custom fields it has, and — for rentals — how long a standard rental period runs. See Inventory and Categories.
2. Add your inventory. Rentable items are tracked one unit at a time; sellable items are tracked by quantity on hand.
3. Add a few customers. Name, email and phone. If you have WhatsApp notifications configured, new customers get a greeting message to confirm their number.
4. Invite your team under Users, and give each person the narrowest role that lets them do their job. See Roles and permissions.
5. Run your first transaction — a rental, a sale, or a service order — and watch the payment appear in the ledger.

Languages

Ceretta App is available in English and Brazilian Portuguese. The language toggle sits in the top bar and your choice is remembered on your next visit. Currency formatting follows the language you pick.
