Former Town defender Tyrone Mings has completed his move from AFC Bournemouth to Aston Villa, netting the Blues an immediate windfall in excess of £1 million with perhaps more to come.
Mings is understood to have moved for an initial £20 million with the fee potentially rising to £26.5 million after top-ups
Town, who made almost £800,000 from Matt Clarke’s move from Portsmouth to Brighton earlier this summer, are included a 10-per-cent-of-profit sell-on clause in the deal which saw Mings join the Cherries for £8 million in the summer of 2015.
That will see the Blues receive £1.2 million now with their share of the fee perhaps eventually reaching £1.85 million.
The additional cash for Mings, who the Blues signed from Chippenham Town for £10,000 in 2012, makes him Town's record sale eclipsing the £8.1 million - probably plus a few hundred thousand more in top-ups - Sunderland paid for Connor Wickham in 2011.
Town could also receive further financial boosts via sell-ons this summer with Adam Webster, currently with Bristol City, understood to be interesting Aston Villa, Leicester, Southampton and a number of others.
The Robins are reported to have set his value at £30 million, however, it seems likely they would have to settle for a fee somewhat lower than that with it having been reported that Villa had a bid of £12 million rebuffed.
Webster, 24, joined the Robins from Town for an initial £3.5 million last summer with the fee potentially rising to £8 million.
The Blues are likely to have a sell-on of 10 per cent included in that deal which, depending on how many top-ups have been paid already, could bring in up to £850,000, although Portsmouth would be due 20 per cent of anything the Blues receive as a result of their sell-on from Webster's 2016 move from Pompey to Town.
Ex-striker Kieffer Moore, now with Barnsley, is also believed to be interesting Bristol City with a 10-per-cent-of-profit sell-on also understood to have been part of the deal which saw the 26-year-old move to Oakwell for £750,000 in January 2018.
However, with the club, which already made significant annual losses in the Championship, facing a £9 million loss of revenue due to relegation to League One, the additional income from the sell-ons is unlikely to give manager Paul Lambert a transfer kitty to work with this summer.
