Why isn't a vendor showing up in the MSME-I return? Confirm the vendor is marked MSME Registered with Enterprise Type Micro or Small (Medium is excluded by design), and that there's an open, posted purchase invoice with a remaining balance. Can I change the 45-day period for a specific vendor? Yes, via Payment Due Days (Override) on the Vendor Card — only shorten it if a signed agreement supports it. The Udyam number won't save — why? The format ( UDYAM-XX-00-0000000 , 19 characters) is enforced strictly. Check for typos, stray spaces, or non-numeric characters in the district/sequence segments. Does this file the MSME-I return automatically? No — it produces filing-ready data as an Excel export. Filing on the MCA portal is a separate manual step. Does this track receivables from MSME customers? Not in this version — it currently covers Accounts Payable only.
