Hi how much discount I can get for yearly subscription for quick book plus

Hi there, hktradingtt-gmai.

Welcome to the QuickBooks Community. I'll make sure to share details about discount offers when subscribing to QuickBooks Online. 

We give discounts to our customers who are about to use our product for the first time. With this, when subscribing to QuickBooks Online, you'll be given a chance to experience either the 30-days trial or 70% discount for three months. When you choose a trial, you won't be able to avail the discount. If you purchase directly and paid subscription, you can avail of the discount on any QuickBooks plan.

With regards to the 70% discount, you'll have to pay the full amount once it ends. The same goes with the 30-days trial. You can check our pricing through our Plans & Pricing page.

Please refer to this article to see steps on how you can change your billing details, payment method, upgrade and downgrade your subscription: Update billing, payment, and subscription info in QuickBooks Online.

I'm also adding this article to further guide you in effectively managing your business using QBO: Help guide for QuickBooks Online. It contains topics about advanced accounting, banking, and payments to name a few.

Please know that you can always get back to this post if you have additional questions with QuickBooks. I'll be around to provide further assistance. Have a good one.
