If you're selling your own products on your site using Akeeba subscription, probably you're facing the same issue I had: invoicing.
There are a lot of products for automatic invoicing, but none of them was as flexible as I wanted, so I created a new one on my own.
When a customer purchase an item, this plugin will create a new customer inside TrackTime (if it doesn't exist), will create a new invoice and it will be emailed to the customer.
Choose the invoice template you want to use
Choose an email template to send to your customer, the invoice will be attached to it
The subject of the email sent to the customer with the invoice. You may use the same merge tags you can use in the order success message (please read Akeeba Subscriptions for further information). Leave empty for a default description.
How the subscription will be rendered in the invoice's description field. You may use the same merge tags you can use in the order success message (please read Akeeba Subscriptions for further information). Leave empty for a default description.
If set to Yes, transactions with EU-based businesses with VIES-registered VAT numbers will have the "Intra-EU" not below shown in the notes. This is required to comply with EU legislation for intra-EU B2B transactions where the VAT liability is transferred to the recipient.
The note to be appended to intra-EU, VAT-free transactions. The default text reads:
VAT liability is transferred to the recipient, pursuant EU Directive nr 2006/112/EC and local tax laws implementing this directive.
Determines when to generate an invoice. The available options are:
After the payment This is the default option. An invoice will be generated once the subscription is paid for, i.e. the payment status is set to Completed and the subscription is enabled.
Before the payment When this option is selected, an invoice will be generated as soon as a new subscription with a pending payment is generated. You will have to issue a payment receipt manually when the subscription is paid. This option is usually useful when used together with the Offline payment plugin as many companies require the receipt of an invoice before paying for a subscription.
