Hey, ​@minhye 

For better understanding, could you please provide a screenshot of the invoice?

Sorry, ​@minhye, your message is empty. Could you try again, please?

see?

Thank you, ​@minhye 

Your invoice seems correct.

Your monthly subscription goes from April 11 to May 11, and during that time your plan was changed a few times. Each change triggers a recalculation, and Manychat refunds unused days and charges again based on the new plan.

Here’s what each line on your invoice means:

1. -$12.22 (credit) - PRO 500 contacts

   This is a partial refund for unused days (from April 16 to May 11) after downgrading or switching.

   Monthly cost: $15 → $15 ÷ 30 × 24 days = approx. $12.00

2. $11.55 (charge) - PRO 500 contacts

   This is a partial charge for using the 500 contacts plan from April 16 to April 18.

   $15 ÷ 30 × 23 days = approx. $11.50

3. -$11.22 (credit) - PRO 500 contacts

   This is a refund for unused time when that plan was cancelled again on April 18.

4. $20.37 (charge) - PRO 2500 contacts

   This is a partial charge for using the 2500 contacts plan from April 16 to May 11.

   $25 ÷ 30 × 24 = approx. $20.00

5. -$19.24 (credit) - PRO 2500 contacts

   This is a refund for switching or cancelling the 2500 contacts plan on April 18. Covers approx. 23 days.

6. $18.70 (charge) - PRO 2500 contacts

   This is another partial charge for resuming the 2500 contacts plan from April 18 to May 11.

   $25 ÷ 30 × 22 = approx. $18.33

7. $25.00 (charge) - PRO 2500 contacts

   This is the full monthly charge for your plan from May 11 to June 11.

My calculations have slightly different values because Manychat took the timing of the activity into account when calculating, and that detail isn’t reflected in my calculations.

Let me know if this helps

I see. I understand perfectly. Thank you for your kind reply.

If I send a message to less than 500 people by 6/11, will I get a refund again?

​@minhye Your subscription plan is based on how many contacts do you have in your Manychat account, and not how many messages you send.
If, after June 11, your number of contacts is 500 or less, you’ll pay $15. If not, you’ll pay accordingly.
