Total G-Cloud sales passed £2.8bn in 2017, but over half of spending by government and public sector organisations is still going to large suppliers.
Data published by Crown Commercial Service (CCS) shows that between its inception in 2012 and 31 December 2017, G-Cloud has facilitated £2.85bn of spending - with 52 per cent of this going to what the government classifies as large suppliers.
SME suppliers have cashed in 48 per cent of total sales through G-Cloud, but this has come from 71 per cent of the deals put through the framework.
The figures mark a slight improvement for SME suppliers since the last time data was released, with numbers published for the period up to 31 July showing that just 47 per cent of spend was going to SME suppliers.
Last week the government revealed that over £3.2bn has been spent by the public sector on digital services through G-Cloud and two other frameworks - Digital Outcomes Specialists and Digital Services.
Niall Quinn, director at CCS, said: "In the three years since Digital Marketplace was launched, we have overhauled the public sector procurement landscape, harnessing the expertise of innovative companies and giving thousands of SMEs the opportunity to supply to government for the first time.
"We're now planning the next steps of our journey, making the platform and processes more commercial, more flexible and better tailored to the needs of users - both buyers and suppliers."
CCS has always touted G-Cloud as an SME-friendly framework, but has often come in for criticism for not making it as accessible to smaller suppliers as it should be.
The percentage of spend going to SME suppliers has changed dramatically over the last 12 months, with figures released in January 2017 claiming 56 per cent of sales were going to small suppliers.
Suppliers expressed their G-Cloud frustrations at the end of last year, when CCS confirmed that G-Cloud 9 will be extended for up to 12 months, giving the framework a potentially unprecedented lifespan.
