Gamechanger!

This is something HMRC should really provide in some basic sense. However, Adsum is brilliant. It's going to be such a huge help when we get to self-assessment reminders! Looking forward to seeing where the product goes!

Revolutionary!

I'm surprised no-one has done it before as it heals a massive pain point of managing clients' HMRC liabilities for practices A great app with responsive developers meaning constant development, excited to see where it goes next

Game changing app

We recently attended Accountex for the fourth year in a row (so we are pretty set up with our software offering and only go now to touch base with our suppliers), and then we came across Adsum (Particularly OpenTax)... It caught our attention straight away... we didn't need a demo, we didn't need any sales pitch - they offered the ability to simply see our client's HMRC liabilities in one clean space - sold. We signed up the day after Accountex and are enjoying the software very much so. Thank you!

Really useful app!

We recently started using Adsum and it has been great! It helps us easily identify issues with clients or in one case, an issue where HMRC owed the client money!
