The company reported sales up almost 20% to £45m in the year to the end of March.
Financial director Duncan Spence said it had taken on 3,000 individual retail outlets since the start of the year. It delivers snacks, crisps, biscuits and cakes to 25,000 shops.
Spence added that Snacksdirect was also working on upgrading and replacing the hand-held terminals used by its drivers to register stock.
The new hardware will enable drivers to enter orders and sales quicker, dispensing with the need for manually typing in product codes.
Spence said the move was part of a larger initiative to upgrade its stock management software, which was costing hundreds of thousands of pounds. The company believed the update would mean quicker and more accurate processing.
It is working with a company called Mobile Enterprise Systems on the project, which is due to go live in October.
