The app batches up multiple past parking sessions into a single card statement to reduce clutter on user’s card statements. Sessions will be batched every $5 or 2 days (whichever is earlier) into bills. Hence, please do not be alarmed if you received sms alerts from your bank or noticed you were billed on days you did not park your vehicle. This is the correct behavior of the app.

Basically, every payment is assigned with a Bill ID under your credit card statement. For re-consolidation purposes, you may refer to the respective Bill IDs and their charges from the 'BILL' tab under the History page in the app and match it against the assigned Bill ID under your credit card statement. You may find that some Bill IDs contain only one session whereas some are a combination of two or more sessions. You may refer to the attachment for more information on how to review the individual parking sessions that are batched under the respective Bill ID.

For more details on the batching process, you may refer to the following,

You create a parking session with the app. A pending transaction appears on your card statement, on the day of the transaction, following the pattern "Parking.sg PENDING"
Each time you create a new parking session, a new pending transaction appears on your card statement
After 2 days, or after your pending transactions exceed $5, our billing system consolidates all those pending transactions into a single, new transaction. This is then charged to your card, and appears something like "Parking.sg Bill_abc123"
Thereafter, all your individual pending transactions are cancelled.
The 'Bill' tab on your parking history page shows very clearly when each bill is created, and which parking session corresponds to which bill. This should remove any doubt

Point 3 is the reason why your bills may sometimes be charged on different days from your parking sessions. This is similar to how billing with other services, such as Telcos, work. For example, you may have activated roaming on a particular day of the month, but you'd only be billed at the end of that month's billing cycle. This is similar, just that our billing cycle is every 2 days or $5 reached.
