Dunns Food & Drinks wants to up turnover from £21m to £25m by 2015.
The growth target was confirmed after the firm installed a new £100,000 computer system; it has earmarked a further £110,000 to refurbish its warehouse.
A fleet of new branded trucks will cost another £560,000, while Dunns’ Blantyre head office will be revamped at a cost of £80,000.
Jim Rowan, director of Dunns, which was founded in the east end of Glasgow in 1875 and now delivers to customers across Scotland, said the firm has a clear strategy moving forward.
“We are now clearer as to where we want to be and what we want to achieve in the future,” he said.
“The important thing is we’re all in this together and we’re all headed in the one direction.
“In business it’s important to get the balance right between reacting to your customers’ needs and being proactive enough to offer them tangible support.
“In an economical downturn it’s important to invest.”
