The system will initiate the creation flow or request the prior setup of tax stamping if it has not been activated previously. ## title ### SAT Stamping Activation If this is the first time you are generating a receipt or if your account has not completed tax registration, the system will display the **"SAT Stamping pending"** notification. Selecting the **"Activate stamping"** option will open a window where you must complete four stages: 1. **Organization**: Create and link the stamping organization with the registered legal entity using the **"Create organization"** button. 2. **Tax Details**: Enter or edit the issuer's tax information: * Commercial name and SAT Business name. * Tax regime and support email. * Full address (Street, Ext. No., Int. No., Neighborhood/Colonia, Municipality, State, and Tax ZIP Code). 3. **CSD Stamps**: Upload the Digital Seal Certificate files: * `.cer` file * `.key` file * Private key password 4. **Manifesto Letter**: Digitally sign the manifesto letter to authorize the issuance of receipts before the SAT. title title *** ### New Invoice Form Once stamping is active, the system will enable the **"New Invoice"** form. In this section, you must enter the general transaction details: * **Issuance details**: Date of issuance and assigned folio (e.g., `CED-001`). * **Stamp global invoice**: Selectable option for sales operations to the general public (generic RFC `XAXX010101000`, regime 616). * **Tax attributes (CFDI)**: * **Payment method**: Selection of the applicable scheme (e.g., `PUE — Single payment`). * **Payment form**: Selection of the corresponding code (e.g., `99 — To be defined`). * **CFDI Use**: Tax destination of the receipt (e.g., `G03 — General expenses`). * **Recipient Details**: Selection of the registered customer to whom the invoice will be issued. ## title ### Line Items, Taxes, and Confirmation In the bottom section of the form, you must detail the line items and taxes associated with the invoice: 1. **Item details**: * **Description**: Text description of the item or product. * **Quantity, Price, and Total**: Numerical data for the item. * **SAT Code**: 8-digit identifier corresponding to the tax catalog (e.g., `84111506`). * **Unit of measure**: Selection of the applicable code (e.g., `E48 — Service unit`). 2. **Taxes**: Configuration of applicable rates and taxes (e.g., VAT 16%) or addition of extra taxes via **"Add tax"**. 3. **Payment Terms and Notes**: Optional field to enter commercial terms or informational messages for the client.
