SIFEN e-invoicing in Paraguay: what to automate first

Start by moving each sale from the ERP to the invoice without retyping data, and by sorting out rejections. Fixed rules build amounts and VAT and SIFEN approves; AI only explains errors and your accountant validates tax treatment.

Start now if

  • Your team retypes sale data into the invoice
  • SIFEN rejections are fixed one case at a time
  • You issue hundreds or thousands of documents monthly

Not yet, if

  • You do not yet know your SIFEN route
  • Catalog items have no VAT rate

Frequently asked questions

Are e-Kuatia and e-Kuatia’i the same?

No. They are SIFEN routes with different scope. DNIT provides e-Kuatia’i as a free solution for small invoicers; e-Kuatia requires software aligned with technical specifications. We review the applicable route before proposing an integration.

Can AI issue or approve my invoices?

Approval belongs to SIFEN, not to an AI model. We propose deterministic rules for fiscal data and amounts, with support agents for documents or exceptions, limited permissions and human review.

Can you connect my current ERP?

We first check available APIs, exports and the existing invoicing workflow. The diagnostic determines whether to integrate your system, work with its provider or build a specific component.

Does this include tax advice or DNIT authorization?

No. This is an engineering service. Your accounting lead validates obligations and tax treatment; taxpayer authorization belongs to the taxpayer and DNIT. We do not promise approval or regulatory timelines.
