David Lampitt has assured Pompey they will be paid this month.
The Blues’ chief executive made the pledge after meeting with manager Michael Appleton on Wednesday night.
The club’s future is under threat after owners Convers Sports Initiatives went into administration.
Joint-administrator Andrew Andronikou has stressed Pompey’s financial situation means a new investor urgently needs to be in place before February.
In the meantime, Pompey’s staff were paid November’s wages earlier this week.
Appleton has been told by his chief executive there is also enough short-term funding to fulfil December’s pay commitments.
And the Blues boss admitted the meeting with Lampitt had left him feeling optimistic.
He said: ‘The meeting with David went fine, not a problem.
‘From a football point of view it is business as usual. Everyone is aware that obviously CSI are in administration.
‘I have been told from a funding point of view we are okay in the short-term.
‘The lads were paid for last month and we’ve been assured we are going to be paid this month.
‘From their point of view they are delighted. The lads get looked after, there will never be a problem for them.
‘I will constantly speak to David and be in contact with him daily just to make sure we are still singing from the same hymn sheet and that any information he is receiving I am getting as well.
‘And we have been made aware we will be paid for this month, so that’s a bonus.
‘Where the fault lies and who is to blame I am not sure. But I know I have got a role to do on the football side of things and that is what I will continue to do.
‘There are a few games to be dealt with before the end of December, and the players know their roles don’t change in what they are expected to do on the field.
‘Obviously, what has happened is a concern for the football club as a whole, of course it is.
‘But if we can get a few performances and decent results on the field, it will go a long way in lifting the spirits of the football club because the fans have had to take a lot of rubbish and stick over a long time now.’
It has been an eventful first three weeks for Appleton at the Blues helm.
Yet he has no regrets on walking out on West Brom for his first managerial role.
He added: ‘I have no regrets at all – I just see it as another big challenge.
‘At the end of the day the people within the football club are still the same people within the football club.
‘The fans will always be the same.
‘We’ve got the best fans in the country and I am sure they will show that again tomorrow against Coventry.
‘I just see it as a challenge I will meet head on.
‘I have never ducked or pulled out of anything in my life – and I don’t intend to.’
