Important Features on Zoho Invoices

Good morning,

We use Zoho Invoice with satisfaction, but there are some features that we really need. We need to know if they are planned or even if we can buy customization for us.

1) We need a lot more attributes for the Customers. We need to save the data bank of the customer, name of the account that follows them, Vat code, riba, rid for the authomatic transactions.

2) Example : We have a recurring invoice each 4 months. It 'important that in the invoices generated by recurring invoice is written the relevant period. For example, we need to create automatically something like this "payment for hosting of site www.xxx.com (February to May 2012)"

3) API for recurring invoices. We need for integrate our contract's database.

4) API for programming events. When an invoice expires would be nice will be called one of our API that disable / block the customer's service.

We'll be kindly appreciated all feedbacks on these tasks.
