Great piece of software that lets you see all HMRC PAYE, VAT and CT liabilities due along with due dates.

Fantastic product and helps manage deadines!

This is a great product that linkes to HMRC and creates a list of our client's various tax deadlines together with the liability amounts in one place, it acts as a double check to our CRM system to ensure we don't miss a deadline and enables us to keep an eye on client liabilties to ensure they are paying what they need!

We had the issue of distributing HMRC user access whilst also combined with multiple HMRC accounts for different services. We came across Adsum when we were not particularly looking for it but knew we needed it. It has been a breath of fresh air and everyone behind it has been hugely friendly, knowledgeable and helpful.
