The problem
SDI holds every electronic invoice issued to or by a company, but the ERP only sees what arrives through its own transmission channel. Some documents never get there:
- Invoices issued on the company's behalf by a customer or a third party (self-billing). They reach SDI through the issuer's channel, so the company's intermediary never receives them; they exist for the company only in the Fatture e Corrispettivi portal of the Agenzia delle Entrate.
- Companies with more than one transmission channel, for example shops sending through their own channel while the head office uses another: no single channel sees all the documents.
- Documents handled outside the ERP, which are missing from the books at VAT settlement.
The same need arises in bulk, for the whole history of a legal entity:
- A new ERP go-live: the finance team wants the previous years' invoices available in the new system, not only in the old one.
- A change of intermediary: the documents held by the previous provider must be retrieved and kept.
What the service does
Memento holds its own SDI accreditation with access to the bulk services (servizi massivi) and to the Fatture e Corrispettivi portal. The service retrieves, per legal entity and period, the complete list of documents that SDI holds for the company, compares it with what is recorded in the ERP, and:
- lists the documents present in SDI and absent from the ERP, and the reverse
- if needed, loads the missing documents into Business Central or Dynamics 365 Finance & Operations, as issued or received documents
- for a history migration, loads all the documents and notifications of the agreed period, and delivers the original XML files as an archive as well
- delivers a reconciliation report

How it works
- Authorisation: the company delegates Memento for the retrieval of its documents from the Agenzia delle Entrate services and provides the required credentials.
- Retrieval of the documents for the agreed legal entities and period.
- Comparison with the ERP and review of the differences with the finance team.
- Loading of the missing documents, in a test environment first when the volume requires it, and delivery of the report.

Access through API
The same data, the documents retrieved from the Agenzia delle Entrate and the comparison with the ERP, is also available through a REST API, for companies that want to run the check from their own systems or integrate it into an existing monitoring flow.
Pricing
Quoted per legal entity and period, as a yearly service. History migrations are quoted once, depending on the volume of documents.
