How to issue invoices for Mercado Livre sales

By Equipe Facilwork

To invoice a Mercado Livre sale in Brazil you must generate an NF-e with the order data (buyer, items, shipping) through a SEFAZ-authorised issuer before dispatching the product. You can do it manually with your state’s free issuer, but daily sellers usually automate it with an ERP that pulls order data and issues invoices one by one or in batch.

Who must issue an NF-e when selling on Mercado Livre?

Companies under Simples Nacional, Lucro Presumido and Lucro Real must invoice every sale. MEI (micro-entrepreneurs) are exempt when selling to consumers, but must issue when selling to another company (CNPJ).

  • MEI selling to a consumer: exempt by law (still recommended for control).
  • MEI selling to a CNPJ: mandatory.
  • ME/EPP under Simples Nacional: mandatory for every sale.
  • Lucro Presumido or Real: mandatory for every sale.
  • Mercado Envios Full: an invoice is required to check stock into the fulfilment centre, regardless of tax regime.

When should the invoice be issued?

The practical rule: issue the NF-e after payment is approved and before dispatch. The DANFE (printed version) travels with the product or is attached to the parcel, depending on the shipping type.

Manual step-by-step

  1. Open the order in the Mercado Livre panel and copy the buyer data (name, CPF/CNPJ, address).
  2. Open your NF-e issuer (your state’s free SEFAZ issuer or your system’s issuer).
  3. Fill in the recipient, items sold (with correct NCM and CFOP codes), shipping cost and operation nature.
  4. Transmit the invoice to SEFAZ and wait for authorisation.
  5. Download the XML and DANFE, attach the invoice to the Mercado Livre order and print the DANFE for dispatch.

This flow works but does not scale: every invoice means retyping data that already exists in the order. With dozens of daily sales, typos and time spent become the dispatch bottleneck.

Common mistakes that block issuance

  • Wrong CFOP on interstate sales to final consumers (watch the DIFAL).
  • Incorrect or generic NCM in the product record — SEFAZ may reject the invoice.
  • Buyer CPF/CNPJ typed incorrectly when copying manually.
  • Forgetting to attach the XML to the Mercado Livre order.
  • Issuing after dispatch, creating date mismatches.

How to automate with an ERP

An ERP integrated with Mercado Livre removes the retyping: the order arrives with buyer, items and shipping pre-filled, and the invoice goes out in one click — individually or in batch for every ready order. In Facilwork, issuance happens directly against SEFAZ inside the order flow (picking → invoice → label → dispatch), supporting Simples Nacional, Lucro Presumido and Lucro Real.

In practice, an operation like Yespack — which has processed over 13,000 orders and issued over 1,500 invoices through Facilwork — invoices the whole day in minutes without leaving the orders panel.

Frequently asked questions

Does an MEI need to invoice Mercado Livre sales?

Sales to consumers are exempt by law. Sales to a CNPJ require an invoice. Mercado Envios Full requires invoices for stock inbound regardless of regime.

Can I issue invoices in batch for several orders?

Yes, with an integrated ERP. In Facilwork you select the ready orders and issue all invoices at once, directly against SEFAZ, with each order’s data pre-filled.

Does NF-e work under Simples Nacional?

Yes. Simples Nacional issues NF-e normally; what changes is CSOSN instead of CST and the taxation form. Facilwork supports Simples Nacional, Lucro Presumido and Lucro Real.
