Next best offer (NBO) is the product or plan a company's rules or models pick as most relevant for one customer at one moment. Telecom operators and banks use it to turn service contacts into sales, for example a larger data plan after a bill with overage charges.
NBO is often discussed alongside next best action (NBA). Next best action is wider, since the best next step may be a service fix, a retention move, or no offer. See also upselling.
How next best offer works
Data. The customer's products, usage, payment history, reason for contact, and earlier responses to offers.
Eligibility. Rules remove offers the customer cannot take, such as a plan not sold at their address or credit they do not qualify for.
Ranking. A model or a scorecard ranks the eligible offers by likely acceptance and by value to both sides.
Hold-back checks. Rules suppress every offer when the moment is wrong (more below).
Delivery. A human agent, an AI agent, the app, or an email presents the offer, with the exact price and terms.
Feedback. The answer is recorded. A decline suppresses that offer for an agreed period, and both answers inform later ranking.
Next best offer in telecom and banking
Telecom. A data add-on after overage charges, or faster broadband when fiber reaches the address. A device upgrade near the end of a commitment, or a retention offer when a caller asks to cancel. Conversational AI for telecom covers the service calls these offers follow.
Banking. A savings account after a salary deposit, a card upgrade, or travel insurance. Credit offers carry extra duties. The new EU Consumer Credit Directive requires creditors to say clearly when an offer is personalized through automated processing of personal data (Directive (EU) 2023/2225, Article 13). Member States apply it from November 20, 2026.
For telecom and other non-financial distance contracts in the EU, the trader has to say in advance when a price was personalized by automated decision-making. That duty sits in Article 6(1)(ea) of the Consumer Rights Directive, added by Directive (EU) 2019/2161. The Consumer Rights Directive does not apply to financial services (Article 3(3)(d)).
When to hold back an offer
An offer on a service call tends to land best once the customer's problem is solved. Rules can hold it back in these situations.
An open complaint, fault, or outage. The customer is still waiting for the fix.
Arrears. An offer that raises the bill can deepen the problem.
Signs of vulnerability. Distress, illness, or confusion call for a person (see vulnerable customer detection).
Identity not confirmed. Account-specific offers need a verified customer.
An objection to marketing. Under the GDPR, a person may object at any time to processing for direct marketing, including related profiling. After an objection, the data is no longer processed for that purpose. The right has to be brought to the person's attention explicitly, at the latest at the first communication (Regulation (EU) 2016/679, Article 21(2) to (4)).
Measuring next best offer
Offer rate. Offers made as a share of eligible contacts.
Acceptance rate. Accepted offers as a share of offers made, counted after any withdrawal period.
Revenue per contact. Added revenue across all eligible contacts, including those with no offer.
Early cancellations and complaints. Either can point to pressure or misunderstanding during the offer.
Service impact. First contact resolution, repeat contacts, and satisfaction on contacts with an offer, compared with a control group that hears none.
A team measured on offers made will tend to make more of them, so the offer rate works best next to acceptance, cancellations, and complaints.
Frequently asked questions
What is the difference between next best offer and next best action?
Next best offer picks a product or plan to propose. Next best action picks the most useful next step of any kind. That may be a service fix, a retention move, a payment reminder, or no offer at all.
How is a next best offer chosen?
Eligibility rules first remove offers the customer cannot take. A model or scorecard then ranks the rest by likely acceptance and value. Hold-back rules can suppress every offer when the moment is wrong, such as during a complaint.
Can an AI agent make offers on a service call?
Yes, once the reason for the call is resolved and the rules return an eligible offer. The agent states the price and terms exactly as the offer system returns them and records the answer. Negotiated offers and questions beyond the offer data go to a salesperson.
Do customers have to agree to receive personalized offers?
It depends on the country and the channel. In the EU, the GDPR gives every customer the right to object to direct marketing at any time. National marketing rules may add consent requirements, so it is worth settling the rule per market with counsel.
