This is an updated version based on my talks with these companies and their credit departments. A few may have reported in the past but as of today 9/18/2019 some do not
MSC Industrial - Does not report
Summa Office Supply - Tier 1 Reports to Credit Safe and Experian - Tier 2 reports to Dnb
Strategic Network Solutions- Reports to Credit Safe and Experian
Grainger - Experian and DNB
Quill- Experian and DNB
Uline - Experian
Seton - Does not Report
Gemplers - Does not report as of January 2019
These are the short list of companies that do or do not report. If you know of more that report at this very moment in time please share. Hopefully this can help out new businesses that are looking to build credit. No need to waste time on companies that that used to report and now do not anymore.
Thanks for the list. I was told Supply Works reports to Experian and I believe they're a tier 1 vendor. I recently saw 2 additional accounts show up on my D&B file, but not sure which ones they are. I need 2 more I guess before I get a Paydex.
