Why incorporate

Selling on MercadoLibre from abroad requires a real Argentine company.

MercadoLibre and other marketplaces require a local CUIT, compliant electronic invoicing and a registered address before you can sell. SAXIA incorporates a SAS or SRL that meets every requirement, so you can start selling without living in Argentina.

Legal structure

Formation strategy, legal address, representation, filings and contracts, including SAS incorporation for e-commerce and marketplace sellers.

Marketplace compliance

CUIT registration, Convenio Multilateral and automated electronic invoicing, so every MercadoLibre sale is properly taxed and documented.

Governance

Clear administration, signing authority and record-keeping so the company runs smoothly without you on the ground.

IP protection

Trademark registration and catalog protection, so your brand and MercadoLibre listings are defended from infringement.

Banking readiness

Professional files and compliance preparation for banks, MercadoPago, fintechs and public bodies.

The SAXIA platform

Legal, tax and operational infrastructure in one place.

We connect company formation, tax registration, marketplace connection, intellectual property and ongoing management into a single operating foundation for foreign-owned businesses in Argentina.

How we handle access

We never ask for your passwords. For ARCA, we register as an authorized relationship on your Clave Fiscal, not your login. For MercadoLibre, we use secondary-user access with only the permissions each task needs. For your bank, we work from your CBU and statements. Your credentials stay yours, always.

Start with clarity

Selling on MercadoLibre starts with the right company.

Your Argentine company starts with a structure that banks, MercadoLibre, tax authorities and partners can recognize.
