Please check memory cost- what is the charge on. what could have costed it ?

Your $201.77 invoice (Jul 23 - Aug 23) breaks down as:

Memory:          $190.30
Disk:              $9.01
Network:           $1.32
Object Storage:    $0.71
vCPU:              $0.42
Agent Usage:       $0.01
Subtotal:        $221.77
Pro included:    -$20.00
Total:           $201.77

Memory accounts for 94% of the bill. You are charged per MB per minute of allocated memory while your services are running. With over 822 million MB-minutes consumed over the cycle, your services were holding a significant amount of memory around the clock. If any services are running idle, enabling App Sleeping will stop billing for memory during periods of inactivity.

You can set up usage alerts, limits, and view your usage breakdown, including per-service costs, by heading to railway.com/workspace/usage.

i was not aware of "If any services are running idle, enabling App Sleeping will stop billing for memory during periods of inactivity." can you do one time waiver ?

also i found there was 32 GB memory allocated. i am lowering it

Lowering that 32 GB allocation will make a big difference on the next cycle. To look into a one-time waiver on the $201.77 invoice, we need one more step: please set a compute hard limit under $201.77 on your workspace at railway.com/workspace/usage so a bill like this cannot recur. Once that is in place, reply here and we can take another look.

i have set it to 150$, although i wanted to set to 50$ , but its not allowing due to Est Credits Required -> $ 157.97 .

Thanks for setting that hard limit. As a one-time act of goodwill we have applied a $105.00 credit to your invoice, reducing it from $201.77 to $96.77. You can pay the remaining balance here.

Thanks . card is not going through will try in sometime. sorting with bank

The $96.77 remaining balance is ready whenever your bank clears the card. You can pay directly via the hosted invoice link once that is sorted.

Done
