If you are running your business from home then having all your financial information organised will save you time and headaches searching for invoices and receipts when it comes to reporting time. There are numerous different services and apps, so I have listed ones I use or recommend. If you have an accountant it is worth checking that they use the same service as you. They will be able to access your financial records, make amendments and report to the relevant government bodies on your behalf.
