It took ConnectBooks three weeks to onboard us. The difference in support was a chasm. ConnectBooks have the ability to map products between QuickBooks and your marketplaces with a simple excel sheet - like every other application. Synder do not have this facility, we worked with their technical team but they were slow and provided incomplete mapping and support - more so they did not deliver what was promised, only 10% (enough to fill a screen). ConnectBooks focus on payouts which is all that is needed - no more gazillion new customers interfering with our wholesale business. We asked for a refund of some of the fees we paid so that we could pay the data for our ConnectBooks implementation but they refused. Initiated a credit card dispute. I am disappointed with this experience, I see many good reviews here but recently some very negative ones. I believe this is an account management issue with a specific account manager that needs to get fixed and made right by Synder management.

Be very careful, if you are thinking of using Synder - it could cause more problems than it solves, and can be incredibly unreliable: we've been using Synder for just over a year, to connect Shopify to Xero, as it had a functionality we could not find elsewhere. But in that time we have had 3 or 4 major incidents, where Synder has created massive accounting issues. Often, these issues seems to happen following Synder 'updating' something, presumably from not checking for bugs properly. For example the latest issue saw Synder not create invoices for £4700 of orders, and instead applied the value of these orders as payments on unpaid invoices, so removing over £9000 of sales from our cashflow and accounts; it took me 2 days at the worst possible timing to manually fix the accounts. Or a previous incident, when in trying to fix another issue, their support ended up duplicating a few months worth of certain invoices (not helpful when you use direct debits..). It has basically been horribly unreliable; everything can be working fine for weeks or months, and then all of a sudden some change or perhaps an update occurs and a bug (not that Synder will ever call it what it is) will have been created, and the key question is how log does it take for you to discover, and what havoc will it have caused in the meantime! It often feels like you are Beta testing Synder, and paying for the privilege... And what refund will you get from Synder for the wasted days, the lost income, and the hit to your credibility with your customers, not to mention the stress of having your accounts messed up? Frighteningly little, they will likely offer you a handful of 'sync's' , whilst charging a substantial amount for the app, and rarely parting with a penny of what you have paid. If I knew what I know now, I would have never started using Synder; but you build your systems around the use of such things, and it takes planning and effort to redesign how your business operates. It holds great promise Synder, on paper, but in our experience it has been costly, incredibly unreliable at times, and Synder seems to care little about the effect of bugs on customers.

We tried using this app in our Shopify store for over a year but could not get it to sync properly and it has been a nightmare reconciling our books. After many attempts with their tech support, we were forced to find an alternative solution, which is much less expensive and has been working like a charm from the minute we installed it. To add insult to injury, Synder will not reimburse us for the 11 months this year we will not be using their app. What a waste of time and money.
