What is SUIT

SUIT is the billing and financial management platform for growing businesses in Peru. It automates electronic invoicing (SUNAT), accounts receivable, payment tracking, and tax reporting — so you can focus on your business, not paperwork.

SUIT has three integrated products:

• SUIT Billing — REST API to emit all 8 SUNAT document types. Send JSON, get a signed XML, CDR, and PDF back.
• SUIT Portal — Web dashboard to emit, track, and manage documents without writing code.
• SUIT Finance — Accounts receivable, payment reminders, aging reports, and financial dashboards.

What SUIT handles for you

• Electronic invoicing — 8 document types, XML UBL 2.1, digital signature, SOAP to SUNAT, CDR parsing
• Async emission — If SUNAT is down, your documents queue automatically and send when it recovers. No one else offers this.
• PDF generation — Professional printable documents for your customers
• Automatic email delivery — Send PDFs to your customers automatically
• Accounts receivable (CxC) — Auto-generated when invoices are accepted by SUNAT
• Payment tracking and reminders — Know who owes what, send automatic reminders
• Financial dashboards and Excel exports — Invoiced vs collected, aging, top debtors
