Prisma is an operating platform built specifically for Italian accounting firms. It works alongside your practice management software and handles what it doesn't.
The AI doesn't just read: it understands. It tells a company registry extract from an invoice, an F24 from a payslip. It extracts VAT numbers, amounts and deadlines. It knows the TUIR, anti-money-laundering rules and the Italian Revenue Agency's practices.
Prisma processes certified email (PEC) and client portals day and night. Documents come in, get classified, renamed and filed in the right folder. Every morning you find everything in order.
Data in Europe. Electronic signature with legal value. Automatic ten-year preservation. Complete audit trail for every operation. GDPR, eIDAS and AgID compliant by default.
Twelve tools designed for how an Italian accounting firm really works.
Gmail, Outlook and every Italian certified email (PEC) account in a single view. The AI sorts, matches to the client and flags binding legal deadlines.
Every document comes in, gets read, classified and filed where it belongs. Without you touching it.
Complete 2026 calendar for every tax regime. Automatic reminders via email, push and SMS.
Documents signed by the client in two minutes from their phone. Full legal value, complete audit trail.
Engagement letters and mandates with pre-filled templates. Assisted editor, client FEA signature, automatic filing.
You generate the F24, the client receives it via the app and approves it with an FEA signature. Authorisation under Art. 3(3) of Pres. Decree 322/1998. No more chasing.
Customer due diligence under Legislative Decree 231/2007 with automatic Politically Exposed Persons check. Risk profile by ATECO code, document-based KYC, complete audit trail.
Compliant digital preservation for ten years. Financial statements, invoices, F24 forms, registers. Automatic.
Mobile-first, white-label. Clients upload documents, sign and pay. No passwords.
Automatic generation and submission of TD17, TD18, TD19 to the Interchange System (SDI). Receipt tracking.
Fees that collect themselves. Magic link via email/SMS, the client pays in 30 seconds, automatic reconciliation with the invoice. Powered by Stripe.
The assistant that speaks Italian tax. Ask it about the TUIR, anti-money-laundering, Revenue Agency practice, and it answers in two seconds.
Every attachment that arrives via certified email (PEC), email or client portal passes through Cortex, Prisma's AI engine.
It reads it. It understands it. It matches it to the right client. It renames it according to your conventions. It files it in the correct folder on Drive, OneDrive or the Optlyx cloud.
The next morning you find everything in its place. Without you having touched anything.
