Your accounting software needs

The first step to choosing the right accounting software is to understand what your needs are, so that you can assess what different solutions offer.

  • Any of the leading packages will make it easier to automate routine bookkeeping tasks and prepare for your accounts. Accounting software providers are continually developing new, clever features like automated bank reconciliation and the ability to scan expenses receipts.
  • Make sure you know what sort of tax functionality you require - for income or corporation tax returns, VAT and payroll (PAYE). With the HMRC rollout of Making Tax Digital (MTD), being able to file returns online is essential.
  • The larger your business, the more likely it is that you will want sophisticted management reporting features and software that allows multiple users.

Other practical considerations include how easy the software is to set up and use, integration with your other systems and cost. It's worth asking your accountants which software they recommend to make it easy to share financial information with them.
