The Scottish government is seeking suppliers of desktop and mobile computing equipment in a series of contracts that could be worth up to £100m.
Winning bidders will be signed up to a framework agreement covering supply to organisations across the public sector in Scotland.
The deals cover PCs and workstations, laptops, netbooks and thin client devices, along with associated services.
The tender notice published in the Official Journal of the European Union states that price will be the determining factor in a procurement that looks to gain the benefits of scale from using the public sector's combined purchasing power.
The agreement is expected to last for 42 months, with a deadline for suppliers bidding for the deals of 4 October.
