MITA Peppol Access Point — using Malta's public AP for B2B
When MITA is the right Peppol entry point and when private Maltese businesses should pick a commercial Access Point instead.
Malta runs a dual-track Peppol network: MITA, the Malta Information Technology Agency, operates the public-sector Access Point that all central-government B2G invoicing flows through, but it is also open to private businesses that want a free, low-volume on-ramp into the Peppol 4-corner model. Commercial Access Points (Pagero, Edicom, Tradeshift, B2BRouter and other OpenPeppol-certified providers) are the usual choice for high-volume invoicing, complex ERP integration or value-added services like format conversion and validation reporting. Knowing which AP fits which use case saves Maltese SMEs both time and EUR.
- MITA AP: free, low-volume, public-sector-grade SLA, basic Peppol BIS 3.0 send/receive only.
- Commercial APs: usage-based fees (€0.01–€0.15 per invoice typical), full SLA, ERP connectors, format conversion, multi-tenancy.
- Hybrid: send B2G via MITA, B2B via a commercial AP — both can coexist on the same VAT number.
- All APs are OpenPeppol-certified — choice of provider does not affect legal validity of the invoice.
How it works
You decide on a track. MITA is the right choice if you send fewer than ~200 invoices a year, exclusively to Maltese public buyers, and don't need ERP automation. Commercial APs are right if you have volume, integrate with SAP/Odoo/NetSuite/Xero, need format conversion (e.g. XRechnung ↔ Peppol BIS 3.0), or want validation dashboards and exception handling.
If MITA: you submit the onboarding form on mita.gov.mt, providing your VAT number, contact person, and the legal entity name. MITA registers your participant ID (0007:MT + your VAT number) on the Peppol SMP and issues credentials for the test environment first, then production.
If commercial: you sign a commercial contract with the AP, who registers the same participant ID and connects your invoicing software via API, SFTP, AS4 or a webhook. Most commercial APs include EN16931 validation, signal-level monitoring and a retry queue for failed deliveries.
You configure your invoicing system to output EN16931 XML in Peppol BIS Billing 3.0 — most modern SaaS billing apps (including 4invoices) handle this natively. The AP wraps the XML in an SBDH envelope, applies the AS4 transport-layer signature and pushes it to the recipient's AP.
You monitor delivery via the Peppol MLR (Message Level Response). MITA exposes a basic web dashboard; commercial APs add alerting, reconciliation against the AR ledger and downstream integration with your ERP for status updates.

Frequently asked questions
Is MITA the cheapest option for Maltese SMEs?
Yes for the access fee itself — MITA does not charge for low-volume use. But the total cost of ownership often tilts back to a commercial AP once you factor in the engineering time required to build EN16931 XML output, monitor delivery, handle errors and integrate with your accounting software. A commercial AP that costs €5–€20 a month for an SME usually pays for itself in saved engineering hours within the first quarter.
Can I switch from MITA to a commercial AP later?
Yes — the Peppol participant ID belongs to you, not to the AP. You change AP by deregistering with MITA and registering with the new provider on the Peppol SMP. There's a short transition window (usually 24–72 hours) during which the SMP propagates the change across the network, after which any other corner routing to your VAT number will reach the new AP.
Do I need to use MITA to send to Maltese public buyers?
No — any Peppol-certified AP can deliver invoices to any other Peppol participant, including Maltese public buyers. The 4-corner model is provider-agnostic: your commercial AP routes the invoice to MITA (the recipient's AP) automatically, transparently to you. You do not need to be on MITA's AP yourself to invoice the Maltese public sector.
What's the difference between an AP and an SMP?
An Access Point (AP) is the gateway that sends and receives Peppol messages on behalf of a participant. The Service Metadata Publisher (SMP) is the directory that records which participant uses which AP, so other APs know where to route incoming messages. Each participant has exactly one AP at any time, but the SMP is shared infrastructure operated by OpenPeppol and authority-appointed publishers.
Does MITA AP support receiving inbound invoices from suppliers?
MITA's AP focus is outbound B2G send for public-sector buyers and configurable inbound receive for the small number of private participants registered. For routine B2B inbound (i.e. you receiving supplier invoices via Peppol), a commercial AP with a richer inbox UI, attachment handling and accounting-system push is almost always the better fit.
