Aishat Idris
Nomi is the only software I use for submitting self-assessment tax returns, even for clients we work with who use other software. Its ability to automate a lot of the processes and pull information in from HMRC is one of the many things I like about Nomi. My clients love Nomi too, and the app is great!
Robert Vacarusi
All modules are so nicely integrated that I no longer need 5 different software to do the bookkeeping, payroll, CRM, final accounts and self assessments. The best part is the price which is a fraction of other software like Xero or Quickbooks Online.
Farid Ahmed
Nomisma is a user friendly, easy to use accounting software, a solution for all that a business needs, sunmitting VAT returns ( MTD enabled), preparing and submitting of final accounts, Payroll and CIS linked to bookkeeping, self assessment tax returns. A highly recommended software for any size businesss and accounting practices with great support team.
Angharad Williams
Cannot recommend Nomisma highly enough. I set up my own business last April and was looking for a software which had all the functions I needed as an accountant eg, submitting corporation tax returns, Ltd company accounts, self assessment tax returns etc. The software is user friendly, easy to use and navigate, and saves so much time as everything is connected! Gone are the days of having to update multiple software packages for the same amendments!
Lina Money Valley UK
Brilliant software for Self Assessment, I have been working in tax for 16 years. Nomisma is great for accountancy firms as cost is very low in comparison with functionality. It beats IRIS or TaxCalc in my personal opinion!
