Hopefully you are here because you clicked the link that says "Why do I have a variance" on our sales report. If not, you may be looking for this article - Cash up variances.
But I digress...
There are two reasons for variances on the Sales report itself.
- Rounding - without getting into a technical discussion here - rounding variances of a few cents here and there on a transaction can happen and are normal. (Basically, the rounding happens when we calculate and have to switch between tax_inclusive and tax_exclusive amounts. Other factors are your pricing and how transactions are split)
Having an open tab then cashing up - this will cause variances over multiple days and should not be done. See this article on why you should not leave tabs open over multiple cash ups.
Pro tip - create an account and save the tab to it - then Cash Up!
