I like the ease of reconciling because once you get set up and code a few items it remembers them for next time for a faster job (you still have to check them to see if they are correct first).
I find it fun and satisfying to reconcile in Xero as it is quite visual, you see several lines waiting to be reconciled and then as you work through the transactions, coding them and clicking on the middle button, they disappear. Setting up bank rules is also a huge benefit, as they get coded automatically, ready for you to just hit the green 'ok' button. You can use this for your usual bills for example, electricity bill, local cafe, cell phone bill, internet charges. Although it does take time to set bank rules up to make sure all details are accurate, it saves time in the long run.
I like the fact that customers can upload documents into the files section of Xero and their accountant can see these documents immediately to work on them or code them.
I also like the search function as you can search for a particular number, or the first few letters of a name or business to find relevant transactions.
Being able to generate invoices and email them direct from Xero is great as it saves time.
It is not the software's fault exactly, but because reconciling is so easy there is a temptation to accept what Xero suggests for a transaction and reconcile to this account, instead of pausing and really checking if the code is the best one.
Xero is first and foremost a business accounting software, so the reports it can generate may not be exactly what other users of the software need, like schools for example, who may need a Xero add-on to get what they most need in regards to reports.
