Tilde
Electronic invoicing for Argentina, without friction. Issue A/B/C/M/T against ARCA with a real CAE in milliseconds — multi-CUIT, a real REST API, built for accountants too.

Tilde is electronic invoicing for Argentina, rebuilt without the ARCA pain. Issue Factura A, B, C, M and T, credit and debit notes and receipts — general regime and monotributo — against ARCA with a real CAE that lands in milliseconds, PDF and RG-4291 QR included. When ARCA rejects something, you get an actionable error in plain Spanish, not a cryptic WSFE code.
Multi-CUIT is first-class: one account, N companies, each with its own certificates, points of sale and permissions. It’s built for accountants and estudios — switch context with ⌘K, no re-login, and no per-CUIT cost on the Pro and Estudio plans. Certificates are guided: generate the CSR from the portal or import your .pfx/.p12, and Tilde warns you before they expire. You keep the control, Tilde keeps it tidy.
A real API, made by Argentine devs: OpenAPI 3.1, an official .NET SDK on NuGet, signed webhooks with exponential retry, and a sandbox at 100% parity with prod. Idempotency is baked in — safe retries by Idempotency-Key return the exact same response within 24h, so nothing duplicates. Mercado Pago and Stripe are native, so you charge the invoice from the same send link, and every action is logged with who, when and from where — exportable to CSV.
ARCA, translated to human
No more cryptic WSFE responses or certificates that expire without warning. Tilde gives you actionable errors, manages your points of sale, and emits with a real CAE so your client gets a ready-to-send PDF + QR every time.
