I love that it is so simple to use - my clients can just sign in as they need them! It's also great how well their support team interacts with us (which has been an ongoing issue since we started using this product). Sometimes there are minor bugs or glitches but these have all fixed themselves within minutes of contacting Support. We've had no issues at all during our almost 4 year run-off period where we're still happily paying monthly fees without having used anything from PSABEE yet except when sending out bills which was super quick & painless. The best thing about ProofStuff? They provide free training videos before purchase along with sample files/templates if needed. You get what you pay for after buying into Proofstuifs service. If you want something reliable then look elsewhere because PS will not be able to keep up with demand once people realise its actually capable of doing everything promised. Providing quotes quickly and easily via email.
