Trigger
Final payment received, call scheduled
When the customer's final payment is recorded in InvoicifyAI, the feedback call is scheduled automatically: 1, 7, or 14 days later, or after a custom delay you set.
Customer Feedback Agent: Catch unhappy customers while it's fixable
After a final payment, your agent calls to ask for a 0 to 10 score (NPS) and the reason. Scores of 6 or lower are flagged for your team to follow up.
Not just a score. A chance to make it right.

Tip
Keep it short and realistic. These details shape the agent's responses in real time.Customer Feedback Workflow: Service to Insight in Four Steps
The agent handles the entire post-service feedback loop, from scheduling the call to routing actionable insights to the right team. The agent uses your product and service descriptions for personalized conversations.
Call
NPS score and open-ended feedback
The agent asks for an NPS rating, then follows up with open-ended questions about what went well and what could improve. Voice captures richer sentiment than a form.
Analyze
Score, category, and reason saved
The 0 to 10 score is classified as promoter, passive, or detractor, and the reason is saved in the customer's own words.
Route
Unhappy customers flagged for follow-up
Detractors, negative calls, and callback requests are flagged for your team with the call summary, so problems get fixed before they become bad reviews.
Start the lifecycle earlier with the lead qualification agent to qualify leads before they become customers.

The agent combines NPS collection with deep sentiment analysis, so every completed service gets a professional follow-up that captures actionable retention data.
Automated post-service NPS calls timed to reach customers when feedback is freshest.
Open-ended follow-up questions that capture verbatim sentiment beyond numeric scores.

What a Customer Feedback Call Sounds Like
A post-project NPS call after a $12,000 office renovation: the agent captures a 9/10 score, the reason behind it, and a timeline concern for the team, in one short conversation.
Sample transcript
Post-project NPS call: office renovation
AI Agent
Hi, this is Casey calling from Bright Solutions. We recently completed the office renovation project at your downtown location, and I wanted to check in on how everything went.
Customer
Oh hi. Yes, overall we are really happy with the result. The space looks great.
AI Agent
That is wonderful to hear. On a scale of 0 to 10, how likely would you be to recommend Bright Solutions to a colleague or business contact?
Customer
I would say a 9. The only thing was the electrical phase ran about a week behind schedule.
AI Agent
Thank you, a 9 is great. I have noted the timeline concern on the electrical phase so the team can address that going forward. What stood out most about the project for you?
Customer
The crew kept the site clean every day, and the project manager answered every question fast.
AI Agent
Thank you, that is helpful. I have saved your comments for the team. We appreciate your business.
Outcome summary
What gets logged after the call
- NPS score captured: 9/10 (Promoter)
- Issue flagged for follow-up: timeline delay on the electrical phase
- Reason captured: clean site and fast answers from the project manager
- Call summary and sentiment saved with the customer's call history
One call captures a score, the reason in the customer's own words, and a concern the team can fix. That is the difference between voice feedback and a one-click email survey.
Feedback Calls vs Email Surveys: How the Options Compare
See how a voice customer feedback agent stacks up against email surveys, manual calls, and collecting no feedback at all.
| Option | Response Rate | Sentiment Depth | Cost | Churn Detection | Scalability |
|---|---|---|---|---|---|
| Feedback Agent | Often stronger than email-only | High (voice) | $$ | Real-time | Unlimited |
| Email survey | Typically lower engagement | Low (ratings) | $ | Delayed | High |
| Manual calls | Strong when staff has capacity | High | $$$$ | Variable | Limited |
| No feedback collection | 0% | None | $0 | None | N/A |
After collecting feedback, use the invoice reminder agent to ensure satisfied customers pay on time.
Which Businesses Use a Customer Feedback Agent?
From post-payment check-ins to NPS after every paid invoice, the agent handles routine satisfaction calls while your team focuses on retention strategy and relationship repair.
Use cases
Home services and contractors
Post-job satisfaction calls that show which customers are happy and catch quality issues before they become negative reviews.
Agencies and professional services
Client relationship check-ins after the final invoice is paid that flag unhappy clients before renewal conversations.
SaaS and subscription businesses
NPS after each paid invoice that identifies at-risk accounts early, giving your team time to intervene before cancellation.
Wellness and appointment-based clinics
For clinics that invoice in InvoicifyAI: non-clinical feedback on the booking and visit experience after payment, with staff-review handoff and no diagnosis, triage, or regulated health intake.
Team design
| Agent handles | Your team handles |
|---|---|
| Post-service NPS and satisfaction calls | Escalated complaint resolution |
| Sentiment capture and scoring | Relationship repair conversations |
| Promoter, passive, and detractor classification | Review and referral asks to happy customers |
| Reason capture in the customer's own words | Expansion and repeat-work conversations |
| Churn risk flagging and alerting | Retention strategy and save offers |
Before feedback, ensure proposals close with the estimate follow-up agent.

Frequently Asked Questions
A customer feedback agent is a voice assistant that calls customers after their final payment is recorded to collect a 0 to 10 NPS score and the reason behind it, classify promoters, passives, and detractors, and flag unhappy customers for your team, without manual outreach. It is strictly for feedback: it does not sell or ask for reviews.
The agent asks the standard NPS question (how likely are you to recommend us, on a scale of 0 to 10), then follows up with open-ended questions about what drove the score. Voice conversations capture richer sentiment than one-click email surveys.
Feedback calls start after the customer's final payment is recorded in InvoicifyAI. You choose the delay: 1, 7, or 14 days after payment, or a custom number of days. Calling too early may feel intrusive; waiting too long loses detail.
Yes. Detractor scores (0 to 6), negative calls, and requests to speak with a manager or get a callback are flagged for follow-up on the call record, with the customer's own words, so your team can step in early.
No. The call is strictly for feedback. The agent asks promoters what they enjoyed and asks detractors what went wrong. If you want reviews or referrals, your team can follow up with promoters using the scores and comments saved from the call.
The agent acknowledges dissatisfaction empathetically, asks clarifying questions to understand the root cause, and logs the issue for immediate team follow-up. It never argues, dismisses concerns, or makes promises it cannot keep.
The agent asks the standard 0 to 10 question, then follows up on the customer's answer: promoters are asked what they enjoyed, and detractors what went wrong and how it could be fixed.
Voice feedback calls can drive stronger participation than email-only surveys because they feel more personal and allow follow-up questions. Actual response rates vary by industry, timing, customer relationship, and call script.
Yes. The NPS score, promoter, passive, or detractor category, sentiment, call summary, and follow-up flag are saved with the call in InvoicifyAI, so the customer's history shows how each job went.
Expect results to vary by customer list quality, timing, brand relationship, and whether callers recognize your business. The useful comparison is that phone feedback often captures richer participation and sentiment than email-only surveys.
For routine post-service check-ins, NPS collection, and satisfaction monitoring, yes. Most teams keep customer success managers for escalated issues, relationship repair, retention strategy, and expansion conversations.
Natural, human-like voice is powered by ElevenLabs. Anthropic Claude and OpenAI GPT models support agent reasoning, transcript analysis, summaries, and follow-up intelligence. InvoicifyAI combines those models with your service context, NPS workflow, and CRM history so feedback calls surface low scores and concerns for follow-up.
