Business management software for SMEs, with SIFEN e-invoicing

Marvin is Hadros' business management software for small and medium-sized companies in Paraguay: sales, SIFEN e-invoicing, inventory, purchasing, finance, collections and HR in one application, across companies and branches, in guaraníes and dollars, with payment reminders over WhatsApp.

Everything Marvin organises

  • SIFEN e-invoicing

    Each invoice is signed when issued and sent to SIFEN in batches, with CDC, QR code and KuDE.

  • Multi-currency

    Prices, sales and receipts in guaraníes and in dollars, with the day's exchange rates.

  • Group › Company › Branch

    Several companies and branches under one login; every screen knows where it stands.

  • WhatsApp collections

    Instalments with their status and reminders before and after the due date through WhatsApp Business.

  • Point of sale

    Checkout with barcode scanner, keyboard shortcuts, payments and a customer-facing display.

  • HR and accounting

    Payroll and IPS social security, MTESS labour reports, VAT ledger and financial statements.

A complete core plus modules you add

Marvin covers customers, products and inventory, sales and invoicing, purchasing and imports, finance and treasury, and administration. Add-on modules are switched on company by company, only when hired.

  • Point of sale with dual display
  • Subscriptions and instalments with a contract builder
  • Quotes, services and work orders
  • Accounting and management reports
  • Fleet and vehicle management
  • Conditional sales (try-on and consignment)

Made for the daily life of an SME

A workspace with shortcuts, step-by-step guides inside each screen, Spanish and English, and a notification centre for overdue and upcoming instalments. What used to live in side spreadsheets ends up in one place.
