Harold Verified Customer Reviews (2026)

What is Harold?

Harold acts as a comprehensive automation tool that caters to both contemporary and legacy ERP systems, with the goal of stopping erroneous data from entering businesses. It carefully processes documents by extracting, verifying, and rectifying any errors before they are incorporated into interconnected systems. Unlike many document processing solutions that simply extract data, Harold prioritizes precision by tackling problems such as missing fields, inaccurate totals, incorrect VAT rates, and invalid supplier IDs, while also minimizing the need for manual checks, thereby preventing disruptions in subsequent operations. Through the application of AI, it efficiently collects information from a range of document types, including invoices, receipts, purchase orders, and statements, while automated rules ensure the data's accuracy, allowing only validated information to be sent directly to an ERP system, accounting software, or via a Zapier integration. Users can easily upload documents or direct them to a specific Harold inbox; after receiving them, Harold systematically extracts crucial details such as headers, totals, line items, and references into a structured format, automatically conducting checks and resolving any inconsistencies before exporting the information. Consequently, data can be handed over in various formats such as CSV, Excel, ERP outputs, or through automated Zapier workflows, which enhances Harold's role as an essential asset for upholding data integrity and optimizing efficiency in corporate operations. Furthermore, this streamlined approach not only saves time but also significantly reduces the risk of errors, ultimately contributing to a more productive work environment.
