They have already deposited the money at a notary awaiting the decision of Neymar Jnr to stay at the Catalan club on move on to Paris St Germain.
Neymar was photographed leaving Barca's Ciutat Esportiva base having bid farewell to his team-mates before making a blockbusting switch, with PSG ready to meet his €222million release clause.
The deal is financed by Qatar Sports Investment, who own PSG - and would allow the 25-year-old to pay his own release clause. When they pass the money to the player it will be taxed and that is a bill they will have to foot.
The statement also said: "The player remains under contract at FC Barcelona but with temporary permission to not take part in training sessions".
And Neymar finally landed in Barcelona just before 9:00pm local time (1900 GMT), taking a backdoor exit to avoid the dozens of journalists and a few supporters some wearing PSG shirts who had been awaiting his arrival.
Under the fair play rules - which Andrea Traverso, Uefa's FFP project leader, was last week quoted by Italian newspaper Gazetta dello Sport as saying PSG were now following - a club's wage bill must not exceed 70 percent of its revenue.
Barca's latest statement requesting full payment suggests such an option is not on the table and comes after La Liga president Javier Tebas questioned the legality of such an outlay from PSG under FFP rules.
His representative Wagner Ribeiro, who on Wednesday tweeted he was in Paris, said previous year that his client had been offered a tax-free £650,000 a week to sign for the French club.More news: 'Harry Potter' scribe said to be rewriting Star Wars Episode IX
According to RMC, Neymar will undertake a medical with PSG on Thursday before the club officialise his signing that evening or Friday morning.
Neymar's father will also be handsomely rewarded for his son's move to France.
Barcelona do not want to add to his windfall.
Wagner Ribeiro, a key adviser to Neymar, confirmed on Twitter that the player was in Paris on football related business.
Neymar has three goals and two assists in three appearances this season for Barcelona.
The Brazilian footballer expressed to SPORT his indignation for what they consider a breach of the agreements agreed in the day of his renewal with Barcelona.
PSG must now complete the deal by paying the buyout clause.
Neymar is valued at around 222 million euros, which after negotiation would reduce to up to 198 million, still a world record transfer fee. He will then be free to sign for PSG.
