Match documents

Matching links supporting documents to transactions in your Test of Details.

How Moby matches automatically​

Moby analyzes your reference document and supporting documents to find matches. It looks for common identifiers like:

  • Invoice numbers
  • Dates
  • Amounts
  • Vendor names
  • PO numbers
  • Other reference fields

The AI uses multiple signals together to find the best match, even when identifiers aren't exact.

Writing matching instructions​

When creating a Test of Details, you can provide matching instructions to guide Moby. Good instructions dramatically improve matching accuracy, especially for complex documents.

Easy case: Unique identifiers available​

When documents have clear unique identifiers (invoice numbers, PO numbers), keep instructions simple:

Match invoices to transactions using invoice number.
If invoice number is missing, use vendor name + amount + date within 5 days.
Match bank statements to transactions using:
1. Transaction reference number (exact match)
2. If no reference, use amount + date (exact match)

Difficult case: No unique identifier (e.g., Bills of Lading)​

For documents without unique IDs, guide Moby on what to look for:

Match Bills of Lading (BL) to shipment transactions.
Look for: shipper/supplier name, consignee, ports, shipment dates, 
cargo description, container numbers.
Dates may differ by up to 2 weeks due to shipping delays.
Match delivery notes to purchase orders.
Key fields: supplier name, delivery date, product descriptions, quantities.
Supplier name is most important. Allow some tolerance on dates and quantities.

Tips for matching instructions​

  • Name key fields — Tell Moby what to look for (dates, amounts, names, references)
  • Give context — "Dates may differ due to shipping delays", "Amounts include tax"
  • Mention variations — "Supplier may appear as vendor, seller, or shipper"
  • Indicate priority — "Supplier name is most important"

Handling bundled documents​

If you have multiple documents packed into a single PDF (e.g., a bundle of invoices), Moby may struggle to match correctly.

Solution: Use Split PDF before running your test.

  1. Select the bundled PDF in Workspace
  2. Click Split PDF
  3. Moby detects document boundaries automatically
  4. Review and confirm the splits
  5. Run your Test of Details on the split files

See Handle messy PDFs for more details.

Manual match​

If Moby can't find a match automatically, you can manually link a document to a transaction:

  1. Click the transaction row
  2. Select Match Document
  3. Browse or search for the correct document
  4. Confirm the match

Manual unmatch​

If Moby matched the wrong document:

  1. Click the unlink icon on the matched document
  2. Confirm unmatch
  3. Manually select the correct document if needed

Handling low-confidence matches​

Moby shows confidence scores for matches. Low-confidence matches are flagged with a Review status.

What to check:

  • Is the matched document actually related to this transaction?
  • Are the key values (amount, date, vendor) correct?
  • Is there a better matching document?
Always verify low-confidence matches

Low-confidence matches should always be manually verified before finalizing your workpaper.
