The software packages, which were donated by TimeHarvest and FileMaker International respectively, will help Erskine deliver cost-effective pricing to its customers.
Erskine Print manager Alan Crawley said: "We are obviously delighted to receive such generous donations of estimating software from TimeHarvest and FileMaker, particularly in the current economic climate."
Erskine Print is one of four commercial businesses run by the veterans' charity, which runs five care homes across Scotland and is a leading employer of former service personnel.
"It's very gratifying that the work we do in offering meaningful employment and training to disabled and able-bodied ex-Service people has been recognised in [this] manner," said Crawley.
"The easy-to-use software will help us to sharpen our commercial edge in an industry where producing accurate quotations in very short time lines is vital."
Geoff Stephens, managing director of TimeHarvest, added: "Getting professional, accurate quotes out on time is as vital to Erskine Print as it is to any commercial company. It's our pleasure to support our veterans in this way."
Meanwhile, FileMaker northern Europe regional manager Tony Speakman praised Erskine for its work with ex-service people.
"They do a great job and we were hugely impressed with their efforts in helping ex-Service people into the workplace," he said. "It's an extremely worthy cause and we hope that our donation can help to make them even more productive and successful."
