I set up a plan for £6+ and it changed to £8+ straight away, i only want £6+

Thank you for choosing QuickBooks plan as your accounting partner, @jonocull-sky-com.

It could be that the £6+ you avail is the promotional price. When the discounted price expires, you'll be charged with its regular pricing.

You can also go to the Billing and Subscription tab from Account and Settings. This can help you efficiently manage your payment and plan info, such as viewing your payment history. For more details, please refer to this article: Update your billing and subscription info in QuickBooks Self-Employed.

I've also added this article that can guide you more in navigating QBSE: QuickBooks Self-Employed Overview.

Feel free to leave a comment below if you need more assistance with managing your QBSE subscriptions. I'll be happy to help you achieve your goals. Keep safe always.

If you have to open a new account, make sure to click the Buy button to get the discounted price for up to a few months. If you purchase from the Trial account or switch to other plan, you have to pay the regular rate.
