Vendor Matching
When an invoice arrives in Mod AI, the AI needs to figure out which vendor sent it. Vendor matching is the process of reading the vendor information from the document and linking it to the correct vendor in your directory.
How AI Vendor Matching Works
The AI reads the vendor name, address, and other identifying information from the invoice. It then performs an intelligent match against your entire vendor directory, looking for the closest match. The AI can handle minor differences -- abbreviations, slight misspellings, and formatting variations.
For example, the AI can match "Fed Ex Corp" on an invoice to "FedEx Corporation" in your vendor directory.
How Matches Are Handled
The AI automatically matches invoices to the closest vendor in your directory. In most cases, this happens without any action from you.
- Match found -- The AI assigns the vendor automatically. No action needed.
- No match found -- The AI cannot identify the vendor. An Unknown Vendor notice is created on the invoice, and you must resolve it by selecting an existing vendor or creating a new one.
Note that low confidence on extracted fields (highlighted in yellow) is a separate concept from vendor matching. A field flagged as low confidence means the AI is unsure about the extracted value — for example, a blurry vendor name, an ambiguous date, or a hard-to-read amount. You will see a yellow highlight and a tooltip prompting you to review the field. This applies to any extracted field, not just the vendor.
How Corrections Improve Accuracy
Every time you correct a vendor match, the AI learns from it. For example:
- An invoice arrives from "Staples Inc." but your vendor directory lists them as "Staples."
- You correct the match, linking "Staples Inc." to the "Staples" vendor record.
- The next time an invoice arrives from "Staples Inc.", the AI automatically matches it correctly.
This learning happens at the vendor name level. Over time, the AI builds a mapping of all the name variations your vendors use, and matching accuracy improves significantly.
Common Matching Challenges
| Challenge | Why It Happens | What to Do |
|---|---|---|
| Abbreviations | Invoice says "Intl Business Machines" but vendor is "IBM" | Correct the match once; the AI learns the mapping |
| Typos | Invoice has a misspelled vendor name | Correct the match; matching accuracy improves over time |
| New vendors | Vendor does not exist in your directory yet | Resolve the Unknown Vendor notice by creating a new vendor or matching to an existing one |
| Similar names | Two vendors have very similar names (e.g., "ABC Consulting" and "ABC Consulting Group") | Review the match carefully and select the correct vendor |
| Trade names | Vendor uses a trade name different from their legal name | Correct the match; the AI stores the association |
Consistent vendor names in your ERP improve matching accuracy. If a vendor sends invoices under different names, correct the match once and Mod AI learns for next time.
