Payouts to the vendors of their online earnings are processed through the Paypal Payouts.

5.1 Deposit account

For each vendor, Paypal Payouts delivers the fund to an email address, specified as the Paypal email address in the vendor registration. This email address may or may not be same as the vendor's main/contact email address. To create a free Paypal account, go to Paypal.

Actually, the vendor's Paypal email address may or may not be associated with a Paypal account at the time of vendor registering. If it is associated, the email will automatically deposite the fund into the associated Paypal account. If it is not, the email will come with a clear instruction on how to create a free Paypal account, receive the fund into the account, and subsequently transfer the fund to the vendor's own bank accounts free of charge.

5.2 Payout frequency

The default payout schedule is monthly on the 15th of each month. The payout is conditional on a minimum balance of $100.00 and if the minimum amount is not satisfied, the payout will be postponed until the next month. The default payout is free of charge.

Vendors have the option to select instant, weekly, or biweekly payout.

Note: CAVS reserves the right to disapprove any selection of payout frequency other than the default. The decision will be based on the chargeback frequencies.

6.1 Per song price

In the karaoke player, go to Control Panel > Tools > Serial. The Serial Setting window appears. Under Credit Setup, select "Song". Set the "Credit per $1" to 1 meaning that $1 payment will get 1 credit. Set "Debits oer Karaoke" to 3 which means a Karaoke songs will require 3 credits. This translates to $3 per Karaoke song as 3 credits are equivalent to $3.

Similarly you can set the Per Song price as you wish by changing the "Credit per $1" and "Debits per Karaoke". Note that there are more than one way to set a Per song price. For exanmple, setting "Credit per $1" at 2 and "Debits per Karaoke" at 6 translates to $3 per karaoke song, which is same as before.

Although there are more than one way to set the Per song price, there can only be one unique Per song price. That is, there cannot be two different Per song prices. The same steps apply to setting "Debits per music" which is to play a regular jukebox song, and "Debit per Disc Write" which is to record a singing onto a disc.

6.2 Per Time price

In the karaoke player, go to Control Panel > Tools > Serial. The Serial Setting window appears. Under Credit Setup, select "Time". Set the "Time per $1" to 10 meaning that $1 payment will get 10 minutes. Similarly you can set the Per time price as you wish by changing the "Time per $1". Other settings will not apply.

6.3 Vending prices

Vending prices are the item prices that customers can purchase online using the shopping cart and digital payment. You can decide to have only one vending price and also decide to set it to be same as the Per song price. In the example here, it would be a single item of $3 in the shopping cart. The customers would purchase the item paying $3 and play one karaoke song.

However deciding on a single vending price which is same as the Per song price is not necessary. For example, there can be two items with the vending prices of $6 and $9. This means that the customers, when purchasing online, will have to buy two karaoke songs or three karaoke songs at a time. Such vending prices can be beneficial when considering the processing fees which are disproportinately large for the small amounts. Also they can offer a vareity to the customers.

The vending prices can thus be multiple, up to three, and different from the Per song price or the Per Time price. We recommend you to consult the processing fees listed below for finding your optimal prices.

6.4 Processing fees

There are three groups of processing fees.

Under the default monthly payout plan where there is no payout fee, the comparison shows

Price per song Payment Gateway CAVS Paypal Payouts Remaining
$1.00 $0.03 + $0.49 $0.10 $0.38
$3.00 $0.08 + $0.49 $0.30 $2.13

Under the instant, weekly, or biweekly payout plan, the comparison shows
