The charity is holding a series of business networking events to encourage local companies to support the charity. The first Barnardo's Showcase took place last month in Edinburgh.
The move has come in response to research carried out by the charity for its centenary year, which showed that the changing nature of property and the property market has had a severe impact on fundraising.
The amount being raised from house-to-house collections has fallen by 75 per cent in the past 10 years - the result, said Barnardo's, of fundraisers being denied access to large blocks of flats as security systems spread.
The charity has also reported a 28 per cent drop in the number of legacies bequeathed to it over the past 10 years.
It cites an increasing number of elderly people having to pay for their nursing care or choosing to leave their money to debt-burdened children.
A spokesman for the charity said that historically Barnardo's would have been the sole charity or one of two charities named in a will; in 2005 the legacy is more likely to be split between five charities.
Frances Benton, head of fundraising for Barnardo's Scotland, said: "We are having to tap into many other sources of income."
