Invoice Automation: From ERP Data to a Sent PDF
Invoice automation generates invoices from your ERP or billing data, sends them to customers and follows up on payment without manual work. It is one of the fastest automation wins for finance teams because the process is repetitive and the data already exists.
Steps in an automated invoicing process
- Trigger: an order is fulfilled, a milestone is reached or a billing date arrives.
- Collect data from NetSuite, SAP, SAP Business One, Priority or your billing system.
- Generate a branded PDF from a template, with line items, taxes and payment details.
- Sign with a digital signature where invoices must be tamper-evident.
- Send by email and store the PDF in the right folder or system.
- Follow up with automatic reminders for overdue invoices and update the CRM.
Batch invoicing
Many companies issue most invoices at month end. Batch generation creates hundreds of invoices or statements in one run, while still personalizing each document.
Incoming invoices are a different process
Outgoing invoice automation creates invoices. Accounts payable automation handles invoices you receive, extracting their data and routing them for approval. Both can run on the same platform.
