Letters have been sent out to those business owners with a rateable value of £51,000 or less who have been identified as being eligible for one of the grants.
Instructions in these letters will invite business owners to complete an online form with their details.
Once responses have been received, Sandwell Council will verify the details provided and assess who is eligible for a grant and transfer money straight into the accounts of businesses.
Businesses who have received a letter may be eligible for grants if on 11 March 2020 they were in receipt of Small Business Rates Relief and have a rateable value of less than £15,000 or alternatively if they are a retail, hospitality and leisure business operating from smaller premises with a rateable value of over £15,000 and below £51,000.
Councillor Yvonne Davies, leader of Sandwell Council, said: "We are very lucky in Sandwell that in normal circumstances we have a fantastic thriving business community who employ and serve many of our residents.
“We want to do all we can, for the hundreds of businesses in Sandwell, at this really challenging time, to make sure all the grants available get to those who are eligible as quickly as possible.
"I urge businesses to reply as soon as they can. We will start transferring money after the Easter break."
