Find invoices in mixed PDFs
— AI detection & auto-split

Most businesses think scanning is the hard part of going paperless. It is not. The real bottleneck hits after the scanner produces a single 50-page PDF containing invoices, contracts, delivery notes, reminders, and advertisements all shuffled together. Someone has to open that file, scroll through every page, identify which pages are invoices, note the invoice numbers, and manually separate them.

This invoice detection step consumes 60-70% of the total time spent on invoice intake. A study by Ardent Partners found that manual invoice handling costs an average of $10.18 per invoice when you account for labor, errors, and delays. For a company processing 200 invoices per month, that adds up to over $2,000 monthly just for sorting and data entry.

Docusplit eliminates this bottleneck entirely. Upload the mixed PDF, and the AI scans every page in parallel. It recognizes invoices by their structural fingerprint — invoice numbers, line item tables, VAT amounts, payment terms — and separates them from surrounding documents. The entire detection-and-split process takes under 60 seconds, regardless of how many pages the PDF contains.

Finding the invoice is only half the job. The other half is extracting the right data and creating a filename that your accounting team or software can work with. Manually, this means reading the invoice number, identifying the supplier, typing a new filename, and moving the file — 2 to 5 minutes per invoice.

Docusplit handles detection and naming in a single step. Once an invoice is identified, the AI extracts the invoice number and company name and generates a filename like INV-2024-0815_Mueller_GmbH.pdf. This pattern puts the invoice number first for quick searching and the company name second for visual identification.

Every processed batch also includes a CSV overview containing all extracted metadata: invoice number, sender, date, page count, and original page range in the source PDF. This CSV can be directly imported into Excel, Google Sheets, DATEV, Lexware, or any accounting tool that accepts structured data. For businesses that need GoBD-compliant archiving, this metadata trail provides the required documentation automatically.

The value of automated invoice detection scales with document volume and mix complexity. Here are the scenarios where Docusplit delivers the biggest impact.

Accounts payable departments receiving scanner batches: A typical AP team scans incoming mail daily. The scanner output is a single PDF mixing invoices with remittance advices, packing slips, and internal memos. Manually filtering 30 invoices from a 100-page stack takes 45-60 minutes. Docusplit reduces this to under 2 minutes.

Tax advisors processing client document boxes: Clients hand over shoeboxes of receipts and documents at tax season. After scanning, the advisor faces hundreds of pages where invoices, bank statements, and personal letters are interleaved. Docusplit detects the invoices, names them, and exports the metadata — turning a 3-hour sorting job into a 5-minute upload.

Property management companies: Utility invoices, maintenance bills, and tenant correspondence arrive in mixed batches for each building. Docusplit identifies the invoices, extracts amounts and dates, and provides a CSV that maps directly to the cost allocation spreadsheet.

E-commerce businesses: Supplier invoices mixed with customs declarations, shipping documents, and return forms. The AI separates invoices from logistics paperwork, enabling faster booking and cash flow management.

In each case, the core value is the same: Docusplit acts as a specialized invoice detection layer that sits between your scanner and your accounting system, ensuring only correctly identified and named invoices reach the next stage of your workflow.
