Every month companies report their operations to the DGII through text files in a predefined format. These are the four most common.
606: purchases of goods and services
Details your suppliers' receipts: NCF, tax ID, amounts, ITBIS and payment method.
607: sales of goods and services
Reports the receipts you issued, broken down by payment method.
608: cancelled receipts
Lists the NCFs cancelled during the period.
609: payments abroad
Records payments to foreign suppliers.
Avoiding manual work
If your accounting runs on Odoo, you can generate all four files straight from the system, from the same invoices, without re-keying. Fewer errors and fewer hours at every month-end close.
Always check the current format and deadlines on the DGII portal.
