JustGiving's total profit has risen by over 10 per cent, according to 2018 accounts filed last week with Companies House.
Total comprehensive profit (post-tax profit) rose to £3.8m in 2018, up 10 per cent from £3.5m in 2017.
Turnover was relatively stable, with a small increase to £27.2m from £26.9m. There was a substantial drop in staff costs, with a figure of £9.97m down 21.3 per cent from £12.7m in 2017.
This meant that operating profits were nearly 3.5 times greater than in 2017, at £4.1m in 2018, up from £1.2m. But this year JustGiving paid around £500,000 UK tax, unlike last year when it recieved a tax rebate.
The organisation's staff count has fallen for the second consecutive year to 109, from 122 in 2017 and 141 in 2016.
In particular, the IT team at JustGiving has continued to decrease in average monthly numbers, to 54 from 58 in 2017 and 75 in 2016.
Staff numbers had been expected to recover in 2018 because there were a number of vacancies waiting to be filled.
JustGiving’s director salaries fell to zero in 2018, from £530,629 in 2017, with senior management taken on by the US parent company Blackbaud since its £95m purchase of JustGiving in October 2017.
A statement from JustGiving said: “In 2017, JustGiving was acquired by Blackbaud, a global technology company with over 3,300 employees.
"One of the benefits of the acquisition was our ability to put the expertise and world-class technology of Blackbaud to work for charities and fundraisers in the UK.
"The significant number of cyber security and IT specialists supporting JustGiving via Blackbaud are not accounted for in the JustGiving company accounts.
"Our charity partners have access to more resources and better technology than ever before.”
