Best On-Premises Automated Invoice Processing Software

BillyBox is an invoice management tool that connects to your email (Gmail, Zoho, or any IMAP provider) and automatically collects invoice PDFs from your inbox. It extracts key data from each invoice — vendor name, amount, currency, and date — and lets you classify them as business, personal, or ignored using a fast swipe-based mobile interface or keyboard shortcuts on desktop. Once classified, export everything as an organized ZIP file ready to send to your accountant. Supports multiple email accounts, monthly ingestion, duplicate detection, and works with 50+ known invoice domains and 25+ vendor formats. Free tier available, paid plans from €9.99/month.

Capture vendor invoices with flexible and numerous methods, including email, check request, mobile app, or vendor portal options. Extract key data using OCR and predefined app templates for automation with live integration to your ERP solution. By using your existing Office 365 subscription in conjunction with SharePoint and Microsoft Power Automate, you can achieve a robust invoice automation system with lower costs to your company. We have built-in integration with Microsoft Power Automate workflows, SharePoint security, and design, Power App check requests, integrated OCR, and Microsoft Forms vendor onboarding. All this using a platform that you most likely already own. Our EasyAP365 app is integrated with your ERP system. When the invoice is approved it immediately creates the appropriate transaction in real-time and supports both purchase orders and non-PO invoices. The product is based on your Microsoft Office 365 platform.
