Nanonets Multi-Account Detection: Does It Actually Work Automatically?
Nanonets claims to "detect and separate multiple accounts when they appear in one PDF." But the reality is more complex. While Nanonets can process multi-account statements, bookkeepers report manual post-processing to split accounts into separate files for QuickBooks or Xero import.
What Nanonets Actually Offers for Multi-Account Statements
According to Nanonets' documentation, their bank statement processing system includes multi-account handling that can "detect and separate multiple accounts when they appear in one PDF." On the surface, this sounds like automatic account splitting—exactly what accounting firms need.
However, the implementation reveals gaps. Nanonets extracts data from multi-account statements into a single output format. While it can identify account numbers and metadata, the platform doesn't automatically create separate output files for each account—a critical requirement for QuickBooks and Xero imports where each bank account must be imported individually.
This means bookkeepers still need to manually split the extracted data into separate CSV files post-processing, or use custom API workflows to handle the separation—adding time and complexity to what should be a simple conversion task.
What Nanonets Claims
- "Detect and separate multiple accounts"
- Extract account numbers and metadata
- Process consolidated bank statement PDFs
What's Actually Missing
- No automatic separate file generation per account
- Manual post-processing required to split accounts
- API customization needed for true automation
