 ## Notes
 
 - State rules are general information, not legal advice. Each record links to the state's official sources and to
   the exact section on backpr.com (for example https://backpr.com/resources/states/texas#ratios). Confirm with the state agency.
-- The registration software index is published by BackPR, which sells registration software; BackPR isn't included.
+- BackPR competes with the companies in the pricing index, so we left BackPR out of it.
