# Watchdog > Watchdog is an AI-powered invoice validation platform that checks every invoice against contracts and pricing history to catch overcharges, duplicates, and fraud — helping finance teams reclaim money they should never have paid. ## About Watchdog is built by Supersolve AS, a Norwegian company founded in 2025. The platform monitors over 5 billion NOK in annual spend and has found invoice errors worth millions for its customers. Watchdog is not an ERP system. It is a lightweight add-on that connects to existing accounting software via API or manual upload, requiring no custom development to get started. It is designed for finance teams, procurement departments, accounts payable teams, and CFOs who want automated invoice validation. ## How It Works Watchdog follows a three-step workflow: 1. **Find errors**: Watchdog runs in the background, checking every incoming invoice against contracts and historical pricing, and notifies users when it finds errors. 2. **Validate findings**: Users see the invoice, the relevant contract clause, and the calculated impact side-by-side to approve or decline each finding. 3. **Claim overcharges**: Watchdog groups errors into a single case, drafts supplier correspondence, and compiles all proof needed to win the dispute. ## Features - **Enforce contracts**: Activate supplier contracts and get alerted when suppliers charge wrong prices, skip discounts, or violate agreed terms. - **Detect price hikes** (coming soon): Find deviating pricing patterns based on historical analysis on item level. - **Never pay twice** (coming soon): Block duplicate invoices and overlapping purchases automatically. - **Block fake invoices** (coming soon): Detect fraudulent suppliers and suspicious banking changes instantly. ## Getting Started 1. Connect invoices by entering an API key to link accounting software, or upload documents manually. 2. Optionally upload supplier agreements — the AI automatically extracts expected discounts, kickbacks, and other contract terms. ## Customer Results - Morten, CFO at Construction Equipment Group: "Watchdog was very useful getting that confidence" in invoice validation routines. - Christopher, CEO at Ghost Town: Found incorrect price jumps from a main supplier worth 2.5% of yearly spend. - Gaute, CEO at Digg Pizza: Saved 200k by uncovering varying terms at different departments from the same supplier. ## Contact - Website: [https://watchdog.no](https://watchdog.no) - Email: hello@watchdog.no - LinkedIn: [https://www.linkedin.com/company/watchdog-no/](https://www.linkedin.com/company/watchdog-no/) ## Pages - [Home](https://watchdog.no/): Product overview, features, and customer stories - [Contact](https://watchdog.no/contact): Get in touch with the Watchdog team - [Careers](https://watchdog.no/careers): Open positions at Watchdog - [Privacy Policy](https://watchdog.no/legal/privacy): How Watchdog handles personal data - [Terms of Service](https://watchdog.no/legal/terms): Terms governing use of the service - [Security](https://watchdog.no/legal/security): Security practices and data protection - [Data Processing Agreement](https://watchdog.no/legal/dpa): DPA for enterprise customers
