Crossborderit IOSS and DDP

What started out as the earliest solution to IOSS reporting, which worked really well seems to have now deteriorated in to a non-functional service. My integration stopped working in April 2024, in early September 2024 they alerted me to this (I should have noticed sooner, but the whole process is meant to be automated and it just slipped through my radar). They claimed it was because my version of the app wasn't updated and I needed to update permissions... which I can't do. The app developer has to push app updates, and they already had full permissions.
They were reviewing the problem... one month later I log in to pay my invoice. The app still isn't syncing data. A week later, still nothing, and no update from Cross Border IT. I'd been collecting VAT from my customers for months, and sending them off with my IOSS number, relying on CBIT to perform the service for which I was paying them €110 a month.
I finally give up, find a new provider, uninstall their app, and it's taken a further month for them to manually process the data so I can fulfil my tax obligations. I can only hope they fulfil their side of the contract and do declare the payment?
But basically avoid, there's more economical services out there for small business, who also provide a service which actually works, with timely customer service.

CrossborderIT was a good solution for us until they changed their pricing from 1EUR per transaction to 99EUR per month despite their terms stating "CBIT shall have the right to change the fees for the Services at any time by giving the Customer no less than 30 days’ notice.", stopped replying to live chat messages and removed the live chat function. We cannot find any option to cancel our service but will be doing so as soon as we possibly can.

Started with a fair and transparent pricing model but started adding new fees, now have added a 99 euro monthly charge. Would not recommend.
