Does ISPbox generate invoices automatically?

Yes. A scheduled job runs daily, generates invoices for active services on their billing interval and advances each service to its next billing date. You can also add one off charges that land on the next invoice.

Can ISPbox handle tax and late fees?

Yes. You can configure a tax or VAT rate, payment terms and a grace period per tenant, and apply an automatic late fee percentage to invoices that pass their due date plus grace.

Does it support proration?

Yes. First cycle proration is configurable and based on the service start and end dates, so partial periods are billed fairly.

Do customers get a proper invoice document?

Yes. Each invoice is rendered as a branded PDF with your company details and payment instructions and is emailed to the customer, who can also view and download it in the portal.

How ISPbox billing works

Stop running billing from spreadsheets and reminders in your head. ISPbox generates recurring invoices from each subscriber service on the cycle you set, handles proration, tax and late fees, and keeps a running ledger per client so the balance is always right.

Recurring invoices, generated for you

A daily job generates invoices for active services on their billing interval, whether monthly, quarterly, annually or weekly, and advances each service to its next billing date. First cycle proration is configurable, and one off charges can be queued as pending items to land on the next invoice.

Tax, late fees and branded PDFs

Set payment terms, grace period, tax or VAT rate and a late fee percentage per tenant. Overdue invoices can pick up an automatic late fee after grace, and every invoice renders as a branded PDF with your company details and payment instructions, emailed to the customer on generation.

A clean ledger and real statuses

Invoices move through draft, issued, partial, paid, overdue and void, and every charge, payment and adjustment writes a ledger entry with a running balance. That gives you and the customer one trustworthy view of what is owed.
