Missoula's Great Harvest Bread Company and its employees earned $4,100 for the Poverello Center.
The bakery and restaurant donated 100% of Thursday's profits for the homeless shelter's new building on West Broadway.
Employees donated their wages.
The family owned bakery was busy all day.
Poverello is trying to raise $500,000 in a community capital campaign.
"Everybody knows but for the grace of God that could be me," said the Great Harvest's co-owner, Dave Scheel."All it takes is a bump on the head and you could be homeless."
Kristen Border was moonlighting Thursday at the bakery, cutting bread, and offering free slices to every customer who came in.
Border's day job is office manager at Poverello.
Great Harvest's staff and owners are wonderful, said Border. "Breaking bread is one of the most basic things we do at the Pov, and this is a great tie into everything that we do."
Poverello's total building project is more than $5 million.
Construction is expected to start at the old Trails End property in August.
Poverello hopes to move in to its new facility in the winter of 2014.
It is the region's largest homeless shelter and soup kitchen.
