Purchasing a subscription
SpeedInvoice is free to try. After the free trial you need a subscription that cost $11.60 per month. You can purchase this by logging in to the web service of SpeedInvoice here. You make a 50% saving if you purchase an annual subscription compared to the cost of a monthly subscription!
You need a credit or debit card to purchase a subscription. If you don't have one, you can purchase a pre-paid card (search on the net).
You can also purchase an annual subscription with PayPal. Send the email address you registered with PayPal to support@speedinvoice.net and ask for an invoice. You can create a PayPal account for free here.
Google and Apple sell monthly subscriptions through in app purchase, but they are more expensive. Please note that they don't accept gift cards as payment for subscriptions.
Unfortunately you can't pay for a subscription with a bank transfers, as all of our subscription handling is automated.
