Most Salvadoran SMBs still run on Excel, WhatsApp, and paper.
Information scattered across spreadsheets, inventory that doesn't match the warehouse, e-invoices issued late, and cash register closings done by hand at the end of the day. At HayVoy we build platforms that eliminate that friction, with guided implementation and 100% local support in El Salvador.
Electronic Invoicing (DTE) in El Salvador, without friction.
Aura ERP issues unlimited Electronic Tax Documents (DTE), validated by the Ministry of Finance in real time. Covers all 8 regulated document types: Consumer Invoice (FCF), Credit Tax Invoice (CCF), Credit Note, Debit Note, Dispatch Note, Export Invoice, Excluded Subject Invoice, and Settlement Receipt.
Electronic signing, time stamping, submission to the Ministry, and PDF generation with QR happen automatically in under 2 seconds. If the Ministry goes down, contingency mode activates and e-invoices are re-sent when service is restored.
- Issuance in under 2 seconds — signed, stamped, and transmitted to the Ministry without manual intervention.
- Unlimited e-invoices included — Aura doesn't limit you by document count.
- Automatic contingency mode during Ministry of Finance outages (deferred re-sending).
- VAT books (sales, purchases, exports, excluded subjects) generated in real time.
- Legal PDF with QR ready to send via WhatsApp, email, or print instantly.
- Excluded subject invoicing and consignment included, no extra module charges.
- Correlation numbers automatically controlled by branch and point of sale, no risk of duplicates.
