Engagement Rates & Telemetry Scoping Guide

Transparent Consulting & Audit Fee Schedule

Flow Vertex Core provides clear, project-based pricing for technical audits and telemetry architecture engagements. We do not sell software subscriptions or recurring platform licenses; our fees reflect dedicated senior engineering time, laboratory test device runs, code audits, and custom architecture documentation.

Standard Engagement Fee Structures

1. Comprehensive Push Telemetry Audit (Flagship)

• Fee: $6,800 USD (Fixed Project Engagement)
• Duration: 10 Business Days (2 Weeks)
• Scope Includes:
  • Full source code audit of iOS UNNotificationServiceExtension and Android FirebaseMessagingService.
  • APNs / FCM gateway priority and payload configuration verification.
  • Multi-device laboratory latency and battery-saver mode profiling (iOS 16-18, Android 12-15 across Samsung, Xiaomi, Pixel devices).
  • Client-side acknowledgment telemetry specification and PR prototypes.
  • Direct vs. influenced response attribution model documentation.
  • Executive diagnostic summary and technical engineering walkthrough.

2. Delivery Latency & Battery Throttling Diagnostic

• Fee: $3,600 USD (Fixed Assessment)
• Duration: 5 to 7 Business Days
• Scope Includes:
  • Isolation of OEM battery management policies causing background message queuing.
  • APNs HTTP/2 header priority verification (apns-priority: 10 vs 5).
  • P50, P90, and P99 dispatch-to-display latency distribution reports.
  • Recommended gateway throttling parameters and background queue retry configurations.

3. Response Attribution Pipeline Architecture

• Fee: From $4,800 USD (Scoped by Ingestion Complexity)
• Duration: 3 Weeks
• Scope Includes:
  • Standardization of notification interaction event schemas (campaign_id, message_id, interaction_type, deep_link_target).
  • Deep link session context propagation across mobile navigation stacks.
  • Decay-weighted conversion attribution window guidelines (1-hour, 6-hour, 24-hour).
  • Ingestion schema specifications for ClickHouse, Snowflake, BigQuery, or PostgreSQL.

4. Ongoing Technical Telemetry Advisory Retainer

• Fee: $2,400 USD / month (Quarterly Commitment)
• Scope Includes:
  • Up to 15 hours per month of direct mobile telemetry consulting.
  • Architecture review of new push notification campaign formats and interactive actions.
  • Pre-release telemetry testing for major iOS and Android OS version updates.
  • Monthly telemetry discrepancy health checks and reporting reviews.

Factors Influencing Project Scope & Estimates

When preparing custom engagement estimates for mobile applications with bespoke architectures, we evaluate:

1. Number of Supported Mobile Platforms: Single native platform (iOS Swift or Android Kotlin) vs. dual-native or cross-platform codebases (Flutter / React Native).
2. Notification Gateway Complexity: Direct APNs/FCM connections vs. third-party aggregators (Braze, OneSignal, Iterable, AWS SNS) or multi-region internal brokers.
3. Monthly Notification Volume: High-volume applications (exceeding 10 million pushes per month) require specialized stress testing and distributed ingestion load profiling.
4. Attribution Complexity: Applications with multi-step omnichannel conversion funnels (such as banking approvals, food delivery tracking, or multi-currency checkout).

Payment Terms & Invoicing Details

• Currency: Invoices issued in United States Dollars (USD) or Thai Baht (THB) at official Bank of Thailand conversion rates.
• Milestone Structure: Standard audits require 50% initial deposit upon engagement kickoff and 50% upon delivery of final report and technical presentation.
• Payment Methods: Corporate international wire transfer (SWIFT) or local Thai bank transfer.
