Billing in Sarah

Sarah is integrated with AFIP/ARCA electronic invoicing services so you can issue fiscal receipts securely and in compliance with current regulations.

From this module you can:

• View and manage all your invoices, credit notes, and debit notes. In the list you can search by customer name, internal number, or receipt number.
• Check the authorization status of each receipt (CAE, expiration dates, etc.).
• Reissue or download already generated receipts.

General billing flow

1. You record a sale from POS or the sales module.
2. The system calculates amounts (net, VAT, total) according to tax configuration.
3. Upon confirmation, Sarah sends the request to the corresponding service (AFIP/ARCA).
4. If the response is successful:
   • The electronic receipt is generated with number and CAE.
   • The receipt is available to download or send by email.

If authorization fails, you'll receive an error message detailing the reason (e.g., incorrect fiscal data, invalid CUIT, etc.).

VAT, purchases, and fiscal month (Argentina RI)

• On each product (Pricing) you set the VAT rate and, separately, municipal, IIBB, internal or other rates (not VAT: VAT + other taxes). Tribute % is on the net, inside the shelf price. Untouched products behave as before. POS still charges the same amount; AFIP files VAT in AlicIva and the rest in Tributos.
• When receiving stock, optional Record VAT adds monthly purchase credit (separate from including VAT in stock cost). If the supplier invoice has municipal tax, turnover tax, or other charges, record that amount: it is not VAT (AFIP treats it as Tributos, not a VAT rate).
• You can load supplier A/B invoices and credit/debit notes; a credit note reduces that month’s VAT credit. For a credit note, enter the original document’s POS and number.
• Under Sales → Fiscal month you see VAT on sales, VAT on purchases, and the balance from what was actually invoiced (CAE / stored breakdown). Other taxes are shown separately. The dashboard (registered taxpayer) shows the VAT balance only. Export CSV or the digital VAT book TXT (ARCA layouts: sales 266/62, purchases 325/84). B/C purchases do not claim VAT credit in the TXT; if supplier POS/number/date are missing, the credit stays in the month summary only.
• Cancelling an A/B invoice stores the credit note as its own document in the month it was issued. Print lets you choose the original invoice or the credit note.
