We offer multiple methods of payment for your invoices at BetterWebSpace, by far the most popular are PayPal and WorldPay and both of these services offer a subscription type model (Paypal Subscriptions and FuturePay) to save you having to remember to login and pay invoices.
If you have setup a FuturePay agreement and you are still getting ovedue notices for your invoices it's worth checking your agreement is still valid and that the credit or debit card you added to the agreement hasn't expired, you can do this through WorldPay's Shopper Management system.
