# Uruguay free zone companies: billing the region and the world from a zona franca

Many regional hubs sit in Uruguay's free zones. How free zone companies invoice clients in Argentina, Brazil and beyond, and handle several currencies.

## Key takeaways

- Uruguay's free zones offer tax benefits to companies operating within them, subject to requirements on activity and employment.
- Free zone service companies often bill affiliates and clients across Latin America and beyond, mostly in dollars.
- Clients in Argentina and Brazil pay under their own countries' exchange rules, which affect timing and documents.
- Holding dollars and paying regional costs in dollars avoids repeated conversions.

A shared service centre in Zonamerica, outside Montevideo, handles accounting, IT support and customer service for a group's companies in Brazil, Argentina, Chile and the US. It bills each affiliate monthly in dollars. The US parent pays by ACH in a day. The Brazilian affiliate pays through an exchange operation in São Paulo. The Argentine affiliate's payment depends on the BCRA's rules that month.

## Why companies use free zones

Uruguay's free zones offer authorised companies a regime with exemptions from most national taxes on activities carried out from the zone, subject to conditions on activity and on employing staff in Uruguay. They host regional headquarters, shared service centres, logistics operators and trading companies.

## Billing across the region

Free zone service companies usually invoice in dollars. What differs is how each client pays:

- US and European clients pay by bank transfer, ideally to local details in their own country.
- Brazilian clients pay through a Brazilian exchange operation, with IOF and documentation on their side.
- Argentine clients follow BCRA rules on access to foreign currency. These have eased since 2025, but payments between related companies still face specific conditions.
- Chilean and Peruvian clients pay with fewer constraints, often in dollars.

Agree in each service contract who bears transfer charges and taxes on the payer's side.

## Managing currencies

Most free zone companies hold dollars and pay many costs in dollars: software, regional travel, contractors. Uruguayan pesos are needed for local salaries and rent. Converting dollars to pesos on a schedule ahead of payroll, rather than on each receipt, keeps the peso budget steady.

## Records

Free zone status depends on meeting the regime's conditions. Keep contracts with each client, invoices, proof of payment and evidence of the activity carried out from the zone.

## Where Rivet fits

A Rivet business account accepts registered companies after verification, including Uruguayan free zone companies. Approved companies get US account details in their own name on every plan, euro and sterling details from the Growth plan, and on Scale balances in 30 currencies, reais included. Payments are matched to invoices, and payouts go to 120+ countries. Rivet is not a bank; regulated partner institutions hold the funds.
