Master data first
Before changing the circuit, clean up the customer and supplier master: tax identification, address, payment terms and the billing contact.
An error in the master multiplies across every invoice issued afterwards.
Then the pilot
Picking a small group of customers or suppliers and working with them through a couple of full invoicing cycles reveals the real problems before they scale to the whole book.
The Law 18/2022 timetable
Article 12 provides that the obligation takes effect one year after the implementing regulation is published for businesses turning over more than eight million euros, and two years later for everyone else.
Moving early has one concrete advantage: when the date arrives, every software vendor's support queue will be full.
What an auditor usually asks for
- Customer and supplier master data cleaned up
- Invoice series reviewed and justified
- A pilot with a small group before general rollout
- Training plan for those who issue and those who post invoices
How the transition is planned with Kimobox
- 1Take stock of where each invoice comes from today and which channel each one arrives through.
- 2Automate the repetitive part first: data extraction, validation and filing.
- 3Measure time per invoice before and after, so you know whether the change worked.
Starting with the supplier that sends the most invoices saves more than starting with the one that bills the most.
