'You absolutely have to spend time chasing debtors,' says Hannah Rhodes (pictured above), the entrepreneur turning honey into beer. 'And manage your supplier relationships carefully. Without a doubt, there will be times when you have to lean on them to help you with a few extra days' credit.'
Rhodes, who appeared in MT's 35 Women Under 35 list in 2014, started London-based Hiver Beers three years ago after a decade in the drinks industry, including a spell at Meantime Brewery.
Despite making mistakes along the way - including being out of stock for a whole month last summer - Rhodes is now the Queen Bee of the honey-beer industry, producing between 10,000 to 15,000 litres per month and selling it to some of the biggest names on the high street, from Marks & Spencer to Selfridges and Harvey Nichols.
Here, Rhodes teams up with four other entrepreneurs plus Karen Penney from American Express to share tips on staying afloat.
