Total G-Cloud sales have passed £430m after deals worth £37m were made in December. This was a decline, however, on November's £48m sales splurge.
The latest figures show that 48 percent of total sales by value (£208m), and 57 percent of sales by volume, have been awarded to small and medium sized enterprises.
Francis Maude, who recently announced plans to step down as Cabinet Office minister for cyber security and G-Cloud, touted the G-Cloud framework as an example of government helping small businesses.
"87 percent of suppliers on the G-Cloud are small and medium sized enterprises, many of which had never done business with the government before," said Maude in a speech at Sprint 15.
However, the fact that over half of all sales on G-Cloud have now been made by large enterprises (£223m) has raised concerns that small vendors are being muscled out.
Data from the government shows that total sales to large enterprises surpassed those to SMEs in October, and the gap between the two figures is now widening, as the below table shows.
Alastair Mitchell (pictured), former chief executive of G-Cloud vendor Huddle, told V3 that Huddle and other small firms are worried by this development.
"The thing that Huddle and other small businesses in the UK are most disappointed about is that the percentage of business going through G-Cloud to SMBs is going down not up," he said.
"The UK government is the biggest buyer of IT in Europe, so it can transform organisations, small businesses and start-ups by buying more from them. [But] as G-Cloud gets bigger, the big suppliers pile on and [SMB sales] are going down.
"And we in the UK's SMB and start-up community think that's a travesty. It's a huge missed opportunity with the G-Cloud, because we think this could be transformative for the UK's start-ups."
The move by Government Digital Services to update the G-Cloud framework to its sixth iteration could shift the balance of G-Cloud sales in favour of small businesses, particularly as it adds 516 new suppliers to the Digital Marketplace.
These changes, and further digital transformation across the public sector, are likely to see the government buying more IT and cloud services via the Digital Marketplace.
However, G-Cloud sales beyond central government have been less impressive, raising questions about the enthusiasm for wider public sector cloud adoption.
