Validate customer VAT numbers before invoicing
Run every new or changed customer through a VAT number checker against the official registry, write the VAT number validation result back to the record, and alert finance to invalid numbers before invoicing.
Copied
When a customer record is created or its VAT number is changed in [billing/ERP system], read the VAT number and country code and check them against the official VAT registry using [VAT validation service, e.g. EU VIES API, national tax registry API]. Write the validation result, the registered company name and address, and the check date back to the customer record in [billing/ERP system]. If the number is invalid, set an invalid VAT flag on the customer record in [billing/ERP system] and alert the finance team via [finance team notification channel, e.g. email, Slack, Microsoft Teams] so the number is corrected before invoicing.

Problem
Finance teams check customer VAT numbers by hand, looking each one up on the official registry. When the team is busy, the check gets skipped or done late, so invalid numbers end up on invoices. This leads to rejected electronic invoices, incorrect tax treatment, and extra work issuing credit notes and corrections.

Solution
When a customer record is created or its VAT number changes in the billing system, the automation reads the VAT number and country code and checks them against the official VAT registry. It writes the validation result, the registered company name and address, and the check date back to the customer record. If the number is invalid, it sets an invalid VAT flag on the record and alerts the finance team to correct it before invoicing.

Impact
Invalid VAT numbers are caught when the customer is set up rather than after an invoice is rejected, so invoices go out with correct tax treatment and the business stays ready for mandatory electronic invoicing.

Route vendor spend requests to approvers
When an employee submits a vendor spend request through an intake form, the automation reads the request type, requesting department, and amount, then matches that combination against a routing rules table to resolve the correct approver. It creates a request record in the approval tracker, assigns it to that approver, and sets its status to awaiting approval. The assigned approver is notified with the request details and a link to the record so they can set the decision.

Extract invoice data from email attachments
When an invoice arrives in the finance inbox, an AI agent interprets the attached document, identifies which fields are relevant based on the format and content it encounters, and extracts the values that matter for the team's records, such as vendor name, line items, totals, and due dates. It records the structured data in a central sheet.

Extract receipt data from email attachments
When an email in the inbox is labeled as a receipt, an AI agent fetches its attachments, works out which one is the receipt document, and reads it to extract the vendor, the items purchased, and their prices. It logs these details to the expense sheet along with the email's message ID, sender, and date, giving the team an organized record of every expense without manual data entry.
