Sales made by companies of all sizes dropped off during April, with large enterprises seeing sales fall from £21m in March to £17.8m in April.
Small and medium enterprises saw a significant drop of £3m in sales, contributing £14.1m to the G-Cloud pot in April, whereas March saw sales of £17.2m.
Sales value share for SMEs also saw a decline, dropping from 47 percent in March to 44 percent in April, indicating that smaller companies are losing out to the larger technology suppliers, despite the previous denials of G-Cloud director Tony Singleton.
In terms of total cumulative sales, large enterprises continue to push ahead of their smaller brethren, having generated £302m to the total to date, compared to the £289m in sales delivered by SMEs.
However, out of the total sales by volume, SME still contribute 58 percent of all the sales made through the G-Cloud framework.
Central government continued to buy the most cloud services by sales value through G-Cloud, contributing £451m in total sales to date, compared to the £100m sales made to the wider public sector, £39m to local governments, and £3.3m to the not-for-profit sector.
While sales of the various cloud products and services through G-Cloud ebb and flow on a monthly basis, specialist cloud services - the area that attracts the most public-sector spending - dropped by nearly £5m in April to £25.8m.
Software-as-a-service sales also tumbled by £3.4m, falling from £5.39m sales in March to £1.92m in April.
In contrast, infrastructure-as-a-service had a stronger month, with sales rising to £3.5m in April, compared to £2.6m a month earlier.
Cloud platform-as-a-service saw some growth in sales as well, rising from £504,000 in March to £707,000 in April.
Despite G-Cloud sales having passed the £500m milestone back in February, questions still remain over the challenges the procurement framework faces.
Particularly when local government cloud sales remain lacklustre, in spite of the work of some pioneering councils, like Peterborough City Council and its plans to overhaul its IT using AWS cloud.
