For distributors selling online

You sell on Mercado Libre, Tiendanube and in store. Invoicing takes care of itself.

Gestión MMSys receives every online sale, invoices it with a CAE (ARCA's e-invoice authorization code) from ARCA (Argentina's tax authority), attaches the document to the sale and updates stock across every channel. Meanwhile, it tells you which listings make money, which lose it and what you should buy.

  7. vii.RestockingPurchase suggestions based on real demand and orders emailed to the supplier.

Mercado Libre

Every sale, invoiced hands-free

You connect the account once. The system renews access, receives sales and issues the right document for each buyer.

Invoice A or B, automatically

Based on the buyer's VAT status. If the customer does not exist, it creates them with their CUIT, DNI or email.

Invoice attached to the sale

The PDF is uploaded to the Mercado Libre sale and sent by email. If it fails, it retries on its own.

Nothing slips through

Even if a notification is lost, every 30 minutes it reviews what changed and invoices anything pending.

Nothing is duplicated

If the sale already has an invoice, it will not issue another. ARCA numbering stays in order across all channels.

Linked listings

Automatically, by SKU. Uncertain matches are flagged and not invoiced until resolved.

Channel dashboard

Orders, revenue, average ticket, percentage invoiced, top products and buyers, with alerts.
