Invoice Settings
Control how ISPBox bills: currency and tax, the billing cycle (bill day, terms, grace, late fee) with a live timeline preview, numbering, automation, email wording and PDF appearance.
Invoice settings control how ISPBox bills your customers - when invoices go out, how they are numbered, what taxes apply, when accounts become delinquent, and how the PDFs look. It is organised into tabs under Settings > Invoices (needs settings manage).
1. General
Sets your billing basics: the default currency and tax treatment. ISPBox supports an inclusive VAT rate or a non-EU tax rate (the two are mutually exclusive) - see Taxes and VAT for the full detail.
2. Billing cycle
This is where you define your monthly rhythm, with a helpful live timeline preview that recalculates as you type:
- Bill day - the day each month invoices issue (dates beyond the month length fall on the last day).
- Payment terms - days after the bill day before an invoice is due.
- Grace period - extra days after the due date before the account is flagged delinquent.
- Late fee (%) - added when an invoice becomes delinquent (see Late Fees).
You also choose proration behaviour for a service's first invoice and the first invoice after a seasonal resume - prorate the partial period or bill a full cycle.
3. Numbering, Automation, Messages, Appearance
- Numbering - the format and next number for your invoice IDs.
- Automation - auto-email invoices, delinquent enforcement and autopay settings.
- Messages - the wording of invoice and reminder emails.
- Appearance - how the PDF invoice looks (layout, accents).
Use Run invoice checklist at the top to confirm your billing is fully configured, and Save invoice settings to apply changes.
