NBScore: The Intelligence Layer That Picks Your Channel
NBScore lead scoring whatsapp decisions are the core of how NimbleBiz works. Every lead gets a score. Every score drives a channel. No manual rules. No guesswork.
When a lead comes in from a Meta ad, NimbleBiz's AI Receptionist starts qualifying on WhatsApp immediately. Within the first few exchanges, NBScore is already calculating — reading intent signals, urgency cues, engagement depth, and Captured Details like budget and timeline. By the time the conversation ends (or goes quiet), NBScore has already decided what happens next.
That decision is simple: message them or call them.
This post explains the logic behind that choice, the signals that drive it, and why getting it right matters more than most businesses realise.
What NBScore Actually Measures
NBScore isn't a simple points system. It reads six dimensions across every WhatsApp or Instagram conversation:
1. Intent strength — How clearly did the lead express a need? "How much does it cost?" scores higher than "just browsing."
2. Urgency — Did they mention a timeline? "Need this by next month" vs. "sometime this year" matters.
3. Engagement depth — How many messages did they send? Did they answer qualification questions or go quiet after the first reply?
4. Captured Details completeness — Captured Details are the structured fields NimbleBiz collects during conversation: budget, property type, team size, or whatever you configure. More complete = higher score.
5. Deal size signal — Based on what the lead shared, how large is the potential opportunity? A lead asking about a ₹10 lakh project and a lead asking about a ₹10,000 order get scored differently.
6. Scope fit — Does the lead's use case actually match what NimbleBiz (or your business) delivers?
These six dimensions combine into a single score. The score drives the channel. Here's how.
The Channel Decision: Low Score, Medium Score, High Score
Low NBScore: Stay on WhatsApp
Low-scoring leads are early-stage. They haven't expressed clear intent, they've given minimal Captured Details, and they may just be researching. A phone call at this stage is intrusive. It wastes your sales team's time. And it often kills the lead entirely.
For low-score leads, NimbleBiz keeps the conversation on WhatsApp. The AI continues nurturing — sharing relevant content, asking follow-up questions, and watching for signals that the score should move up. If the lead re-engages and intent strengthens, NBScore updates automatically.
No call. No push. Just patience with intelligence behind it.
Medium NBScore: WhatsApp First, Voice as Fallback
Medium-score leads have shown real interest but haven't committed. They answered some questions. They have a genuine need. But they haven't crossed the threshold that signals "ready to buy now."
For these leads, NimbleBiz sends a WhatsApp follow-up first — inside the 24-hour conversation window if available, or a pre-approved template if the window has closed. The message references what they shared: specific enough to feel personal, not generic enough to be ignored.
If the WhatsApp message goes unanswered after a configured wait period (typically 4–8 hours), NBScore can escalate to an AI Outbound Call — a short call from a dedicated retarget voice agent that references the WhatsApp conversation context. The call doesn't feel cold because it isn't. The AI knows what they asked about.
This is the 3-channel ladder in action: WhatsApp free-form → WhatsApp template → AI voice call. Medium-score leads typically get steps 1 and 2. High-score leads get all three, with shorter wait times between each.
High NBScore: Move Fast, Go to Voice
High-score leads don't have time for gentle nurturing. They have budget. They have urgency. They've given you most of the Captured Details you need. They are the leads that close — if you reach them before a competitor does.
For high-score leads, NimbleBiz can trigger an AI Outbound Call without waiting for a WhatsApp non-response. Speed matters more than channel here. The AI Voice Agent calls the lead, references the WhatsApp conversation, and moves straight into closing or booking.
The threshold for "move straight to voice" is configurable. By default, a score above a set level triggers immediate call escalation. Businesses in fast-moving categories — real estate, financial services, coaching — often lower the threshold further. Every missed hour is a lead that another agent has already called.
Why This Matters: The Cost of Getting the Channel Wrong
Most businesses pick a channel and stick with it. Call everyone. Or message everyone. Neither works.
Calling low-intent leads too early is the fastest way to get blocked. Leads who are still in research mode don't want a call. They wanted information. An unexpected call from a number they don't recognise — right after messaging a business — feels like a pressure tactic. You lose the lead and the channel.
Only messaging high-intent leads means slow response on your highest-value opportunities. WhatsApp replies take time. A serious buyer who filled in all their details and said "I need to decide this week" shouldn't be waiting for a back-and-forth chat thread. They should get a call.
NBScore solves both problems at once. The low-intent lead gets patience. The high-intent lead gets speed. Neither gets the wrong channel.
How Captured Details Feed Into the Score
Every question the AI Receptionist asks in WhatsApp fills a Captured Details field. These fields are configurable — a real estate business might capture: property type, location preference, budget range, and buyer or renter. A coaching centre might capture: course interest, current qualification level, timeline to enrol, and budget.
When more Captured Details are filled, two things happen. First, NBScore goes up — because a lead who answered all your questions is clearly more engaged than one who dropped off after the first message. Second, the AI has richer context to carry into any follow-up channel — including the AI Voice Agent call.
That context carryover is what makes the voice call non-intrusive. The AI isn't starting from zero. It says: "Hi Priya, you were asking about the 2BHK project in Whitefield — I'm calling to see if you'd like to book a site visit." That's a warm call. Not a cold one.
The Skipped-Attempt Rule
Here's an important detail about how NimbleBiz handles the retargeting ladder: skipped attempts don't consume retries.
If a lead's NBScore is high enough to skip straight to a voice call, the WhatsApp template attempt isn't counted as a used attempt. If the voice call also fails (no answer, number unreachable), NimbleBiz can still fall back to WhatsApp template as a final reach. The ladder is adaptive, not sequential for the sake of it.
This matters because it prevents high-value leads from getting stuck or exhausted by one failed attempt. The platform keeps trying through available channels until it reaches the lead or the attempt limit is hit.
DNC suppression is respected throughout. If a lead has opted out of calls or messages on any channel, NimbleBiz honours that across all channels — not just the one where the opt-out was registered.
Setting Up NBScore in NimbleBiz
You don't configure NBScore from scratch. NimbleBiz ships with a default scoring model calibrated for lead qualification across common SMB use cases. What you do configure is:
- Which Captured Details fields matter for your business — these feed directly into the score
- Score thresholds for channel escalation — the cutoff between "WhatsApp only" and "WhatsApp + voice call"
- Wait times between channel attempts — how long to wait after a WhatsApp message before triggering a call
- Maximum attempts per lead — so no lead gets contacted indefinitely
Most businesses get this right in their first week. The signals that matter for a real estate inquiry are different from a D2C product inquiry — and NimbleBiz lets you tune accordingly without any technical configuration.
What No Competitor Offers
WATI, AiSensy, ManyChat — they have WhatsApp automation. None of them have a lead-score-controlled channel selector.
WATI has no AI Voice Agent. No outbound calling. If a lead goes quiet after your WhatsApp message, your only option is to send another WhatsApp message and hope.
AiSensy has broadcast and template messaging. No scoring. No voice. No intelligence about which leads deserve more aggressive follow-up.
ManyChat has automation flows. Those flows are rule-based — triggered by keywords or button clicks. They can't read intent. They don't adapt to what the lead actually said.
NimbleBiz is the only platform where a lead's own conversation behaviour determines what channel reaches them next, at what speed, in what sequence. NBScore is the intelligence layer that makes that possible.
FAQ
What happens if a lead gets a high NBScore but doesn't answer the AI call? NimbleBiz logs the attempt and, depending on your configuration, can send a final WhatsApp template as a fallback. The lead isn't marked as lost — it's moved to a passive nurture state where re-engagement is possible if they message again.
Can I override NBScore for a specific lead? Yes. From the unified inbox, your team can manually adjust a lead's status or trigger an action regardless of score. NBScore drives automation — it doesn't block human judgment.
Does NBScore work for Instagram DM leads? Yes. NBScore is channel-agnostic. It reads Captured Details and engagement signals regardless of whether the conversation happened on WhatsApp, Instagram DMs, or Facebook Messenger.
How quickly does NBScore update? Continuously. Every message the lead sends updates the score in real time. A lead who starts cold and then suddenly asks a high-intent question — "what's your pricing for 50 units?" — will see their score move up immediately, and the next automated action adjusts accordingly.
Is there a minimum number of messages before NBScore activates? No. NBScore starts scoring from the first message. Early signals are lower-weight, but the model is active from the moment the lead enters the conversation.
