Ok, i’m a bit confused myself on this one so please bare with me…
When I log a purchase I will then make sure I upload a corresponding invoice…no problem.
Am I suppose to do something similar for Sales? What is a Sales receipt exactly? I do not deal in cash sales, so I figured I do not need to upload anything, my invoices are raised and all paid online.
Just looking for clarification that I’m am logging everything correctly 
You don’t need to upload anything in particular for sales invoices, but if your income is from elsewhere (e.g. an ecommerce site, or retail outlet), you may wish to attach a backing report to it to back up the figures.
For example, if you take £120.00 including VAT from a shop, the till should give you an output of the figures. You may then with to upload that report and attach it to the sales invoice (just incase ;))
You don’t have to, but it would mean everything is in one place should you need it.
Thank you, All of my transactions are online so everything is logged electronically. Easy Peasy
