The three methods below differ significantly in their practical applicability:\u00a0<\/span><\/p>\n<p><b>Scan (Document scanning):<\/b><span style=\"font-weight: 400;\"> This method only converts the physical format to a digital format (PDF, JPG). The data on the scanned document is &quot;dead&quot; data; the system cannot extract, calculate, or automatically account for it. Scanning only solves the need for digital storage, not the operational challenges.<\/span><\/p>\n<p><b>Manual data entry:<\/b><span style=\"font-weight: 400;\"> This is the most traditional way to create structured data, but it comes with a resource bottleneck. At the scale of processing thousands of invoices each month, human error is common when typing incorrect data fields (tax identification number, amount, date), leading to bottlenecks in the reconciliation process.<\/span><\/p>\n<p><b>OCR (Optical Character Recognition):<\/b><span style=\"font-weight: 400;\"> Converting data from images to text can be handled by a computer. Instead of retyping each figure, the system reads, recognizes, and extracts information fields into structured data.
