Whenever a payment goes through, we send you an email about it straight away. You can also check it inside your account — in two places, depending on what you want to see.
The quick check: your plan and the next payment date
Click your name at the bottom of the left sidebar.
The menu shows My plan, Next payment, your traffic usage and Active domains.
If the plan name is the one you bought and Next payment shows a date in the future, the payment went through. (On a free plan the row reads No upcoming payment — nothing is charged there.)
For the full view, click Subscription in the same menu: the Current plan card repeats the plan, the next payment date and your region, and any banner about your subscription appears at the top of that page.
The proof: your invoices
Open Settings → Billing.
Scroll to Invoice history.
The table lists every order with its Order number, Date, Status, Total and a Download column. Where a document is available, you get an Invoice or a Proforma link — click it to download the PDF.
Both the Subscription and the Billing tab are visible to account Owners only.
If something went wrong
A declined charge is stated on Settings → Subscription: Your last payment was declined., with an Update payment method link. Save a working card and the subscription continues — see How to Change Your Payment Method.
A grace period banner (Grace period active since …) means your access is being kept alive while the payment is sorted out.
An expired account says so plainly: Your account has expired — We can no longer display your campaigns. Renew your subscription to bring them back.
If a payment left your bank but none of the above matches what you see, send us the order number from Invoice history at support@optimonk.com and we will check it.
