Sounds like you need an intermediary table between businesses and offers. It would be something like:
BusinessOffersTable OfferID BusinessID Status
It's a many-many table, so for each new offer that is created, you add a record for every business it gets sent to. Then each business can modify the status for each individual offer themselves.
OfferID BusinessID Status 1 1 a 1 2 b 1 3 a 2 1 a 2 2 b 2 3 a
