Billing
MDB operates on a simple, transparent credit system based on unique visitors per month, per site. This page explains how billing works and provides examples to help you estimate costs.Credit System Overview
- 1 unique visitor per month per site = 1 credit
 - Sessions don’t count - Only unique visitors matter
 - Monthly billing cycle - Credits reset each month
 
How Credits Are Calculated
Key Principles
- Unique visitors only - Multiple visits from the same person on the same site in the same month = 1 credit
 - Site-specific - Same person visiting different sites = separate credits per site
 - Monthly reset - Each month starts fresh for credit counting
 - Identification required - Only identified visitors count toward credits
 
Billing Examples

Cross-Month Visits
Scenario: Person visits 
site-a.com 2 times in January and 5 times in FebruaryBilling: 2 credits (1 per month)Explanation: Same person and site, but different months = 1 credit per monthMultiple Sites, Same Month
Multiple Sites, Same Month
Scenario: Person visits both

Scenario: 3 different people each visit

Included
- ✅ Identified visitors - Visitors that MDB successfully identifies at the person level
 - ✅ Unique monthly visits - First visit by an identified person to a site in a given month
 
Not Included
- ❌ Unidentified visitors - Visitors that MDB cannot identify don’t consume credits
 - ❌ Repeat visits - Additional visits by the same person to the same site in the same month
 - ❌ Sessions - Number of sessions doesn’t affect credit consumption
 
Billing Cycle
- Monthly billing - Credits are calculated and billed monthly
 - Reset each month - Credit counting starts fresh each calendar month
 - Usage tracking - Monitor your credit usage in real-time through the MDB dashboard
 
Cost Optimization Tips
Minimize Credit Usage
- Consolidate tracking IDs - Use the same tracking ID across related sites when possible
 - Monitor identification rates - Higher identification rates mean more credits consumed
 - Use options strategically - Leverage pixel options for segmentation without affecting billing
 
Maximize Value
- Implement proper webhook handling - Ensure you’re capturing and utilizing all identification data
 - Use enrichment features - Take advantage of upcoming behavioral and enrichment data
 - Optimize for high-value visitors - Focus pixel placement on pages with your most valuable traffic
 
Dashboard Monitoring
Your MDB dashboard provides:- Real-time credit usage - See current month consumption
 - Historical data - Track usage trends over time
 - Site breakdown - Credits consumed per site/tracking ID
 - Identification rates - Percentage of visitors successfully identified
 
Credit usage is updated in near real-time, so you can monitor consumption throughout the month.
