Xero

Avantages

Professional double entry software at a very affordable price
Accommodates both cash and accrual accounting
Links to financial institutions to get transactions
Uses standard importer recognized by the financial institutions instead of just trying to log in remotely (and triggering fraud alerts)
Can match multiple invoices to a single deposit transaction imported from bank
Can keep using Xero as company grows

Inconvénients

Pre-existing expense categories/descriptions don't map 1:1 with IRS definitions, so I'm having to go back to all my receipts to make sure expenses are entered in proper accounts because I didn't realize this when I switched
More difficult to focus on specific expense categories to check transactions
Have not been able to import historic data from previous app (possibly because it's not double entry) so I am still paying the subscription on that software to retain access to my data
No integration with Craftybase, so I have to enter supply purchases and customer invoices there independently

Avantages

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.

Inconvénients

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.

Avantages

I have been using Xero for a good number of years now and can only recommend it! The usability is fantastic, the ability to see really clearly how the accounts work is groundbreaking in its field. I love the bank reconciliation and the bank feeds. The automation of data is actually fun and linking it into the add-ons can make life a lot easier and save time and money. It is a great way to keep things simple and clear. I love the advisor features, that you can't break it (although you can make a real mess if not careful). For me the biggest benefit is the clarity of the data and the ability to drill down into virtually anything.

Don't use Xero in super complex scenarios and I would recommend that you employ a proper XERO accountant - who actually knows how to use Xero and uses the data when using it though or you will end up paying twice - once for entering the data to xero - and again when the accountant pulls it out into their own software. Overall I would absolutely recommend Xero for people who are more serious than working in spreadsheets but who are turning over £50k-£3m+ with a fairly simple process.

Inconvénients

We have found that Xero does not work well in all scenarios but there are work arounds - the bigger the business and the more complex the processes the less it suits but then if you are bigger/more complex you should arguably be using something else!
Support is not awesome! It can take time and you are often met with unhelpful suggestions. There has been an increased number of 'blips' in the software in more recent months and the support has been almost useless in those cases and I have had to find workarounds. Conversation/instant message support should surely be on the cards?
Another thing that I don't like is the highly evangelical nature of the conferences! It borders on the cultish and if you are not 'in' then you are definitely 'out'! I have not found there to be any benefit to being on the 'directory' for that same reason.

Avantages

For bookkeeping, small and medium-sized businesses this software is a dream. It is the most intuitive and easiest to use of all the accounting software that we reviewed. As an accountant, it is easy to fix user errors and mis-postings. There is a proper audit trail and safety checks built in. There are so many time-saving features like find and recode, repeating bills/invoices/journals, bank rules. The move toward AI is exciting too.

Inconvénients

The reports aren't GAP or IAS compliant so it is no good for reporting, final accounts production or tax. To get accountants interested and recommending Xero in the early days, they promised accountants that Final Accounts Production and Corporation Tax software was in their development queue but it never materialised and they burnt a lot of bridges with accountants when they announced that they had dropped FAP plans. This is why Quickbooks are getting such a big foothold and stealing market share from Xero.

The software is expensive for what it is and you can get a lot more and better for your money with FreeAgent and QuickBooks.

The biggest let down for Xero is that there is no telephone support, at all. Not even call back. You have to email and if you are on the opposite side of the world from New Zealand, it can take a full day to get an inital response and if there is any misunderstanding or info required, it can take days to get your problem resolved. This is really useless and a deal breaker for serious businesses.

Another major failing in Xero is the number of times that the Bank Feed just doesn't work. This is outwith Xero's control and so it can often take months to resolve. This is amateur and best and negligent at worst.

Avantages

Great design, intuitive, great support files and videos, invoicing features are very good, being able to add files to transactions is a big time saver, the fact that it is a full accounting system is great in its price range, although for more complex features you may need an add-on application for example full stock management and stock control.

Inconvénients

The way the contacts database has been developed could be improved to make importing and exporting data easier, that has improved recently with the addition of client codes field. Also greater flexibility of controlling features a user can access would be great.
