# 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.

| Module | What it's for |
|---|---|
| **Rent** | Equipment rental, costume hire, tool libraries — anything booked over a date range |
| **Sales** | Selling products from stock — retail, parts counters |
| **Services** | Repair shops and workshops — any job tracked through a workflow you define |

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](/docs/en/inventory).
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](/docs/en/roles).
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.
