Hi Doug,
We ran into this request about 10 years ago, for a grocery chain, that had a specific requirement (or so they said) for weekly financials.
Their finance group struggled with our suggestion to go to 13 x 4 week periods, and that was the key that weekly F/S would be a bust. So we walked away.
I guess there are some sites that need weekly financials but they don't need Adagio or their volume of users would not be able to be handled by Adagio.
Best,
Brian
