Onboarding, accounted for.

Each charge is quantity × monthly price × billable calendar days ÷ days in the month. The activation day is included. Each batch’s service-month total is rounded to cents before totals are added.

Monthly invoices combine the prior month’s new-service prorations with the current month for services active on the 1st. The onboarding target is for planning only. Forecasts include future batches you enter. The comparison mode uses your original rule: starts in the final seven days also prepay the next month.

Each endpoint has one tier: Core ($9.99), Essential Protection ($49.99), or Advanced Protection ($69.99). Advanced includes one identity allowance per endpoint. Count actual ITDR + SAT activations separately: use Identity activation — included with Advanced ($0) for included identities, or Identity Protection ($29.99 per identity) for standalone and extra identities. Do not log the same identity in both categories. Included activations cannot exceed Advanced allowances available on their start date. Unused allowances do not reduce the Advanced endpoint price. SIEM and 365 backup keep their own quantities and activation dates.

Existing Advanced batches retain their price and provide identity allowances; they do not create identity activation records automatically. Log those activations using the actual dates. This calculator tracks additions and produces invoice previews; it does not send invoices, track payments, or automatically reconcile charges already invoiced elsewhere. Use Edit to correct an entry, not to record a mid-month tier change or removal.

Records save only in this browser on this device. They are not uploaded or shared with other devices. Download backups regularly, particularly before clearing browser data. Restore imports organizations as separate copies. CSV exports use a quantity of 1 and the exact batch total; the description contains the actual units, dates, price, and day calculation.
