The ROI of AI for Customer Service is calculated by comparing implementation costs with savings and additional revenue — there is a clear framework to decide whether it is worth it or not — no guessing. Zenify recorded AI revenue growth of +18% (approved).
TL;DR
- ROI = (lợi ích − chi phí) / chi phí.
- Benefits include savings + increased revenue.
- Include all hidden costs, not just the package price.
- Compared to the scenario without using AI.
- Before/after measurement on real data.
Why calculate ROI?
Deploying AI costs money and time — if you don't calculate ROI from the beginning, it's easy to expand in the wrong places and not know if it's worth it or not. The framework below helps make the decision clear.
Basic ROI formula
`
ROI = (Lợi ích − Chi phí) / Chi phí × 100%
`
The benefits include 2 parts:
Save costs (reduce labor and processing time).
Increased revenue (better conversion, customer retention).
Cost components
Category | Example
Tool Price | Monthly/yearly package fee
Deployment | Configuration, data, knowledge base
Training | Study team time
Maintain | Monitor, tweak, update
Hidden costs | Integration, trial and error, disruption
Benefits ingredients
1. Tiết kiệm thời gian
`
Savings/year = number of conversations × minutes saved × cost/hour
`
AI answering automatically reduces processing time (see 35% reduction in time).
2. Increased revenue
Increase conversions from quick replies (see AI in sales).
Retaining customers is better than reducing churn (see Proactive care).
Sample ROI spreadsheet
Category | Value
AI costs/year | 120 million
Save labor/year | 200 million
Revenue increase/year | 80 million
Tổng lợi ích | 280 triệu
ROI | (280−120)/120 = 133%
