SaaS & B2B Automation

Run upsell and cross-sell campaigns to your SaaS customers on WhatsApp — based on usage signals

WhatsPortal sends personalised upsell messages to customers who are hitting plan limits, using features adjacent to premium tiers, or ready for an add-on — on WhatsApp, where they'll act on it.

A customer is hitting their API limit every week. They haven't upgraded. Nobody told them they should.

01

Expansion revenue — plan upgrades, seat additions, add-on purchases — is the highest-ROI revenue source in SaaS. But most expansion happens reactively: customers upgrade when they hit a hard limit or when your CS team happens to call. Proactive, behaviour-triggered campaigns dramatically increase expansion MRR.

02

Generic 'upgrade now' emails sent to all users on lower plans don't convert. They feel like spam. A message triggered by specific usage — 'You've used 85% of your monthly messages' — feels relevant, timely, and helpful, not promotional.

03

Cross-sell campaigns for complementary products or features have very high conversion rates among existing customers who already trust your brand. But most SaaS teams run these as infrequent email blasts to their full database. WhatsApp, timed to usage signals, performs significantly better.

The solution

WhatsPortal triggers upsell and cross-sell messages on WhatsApp — based on customer usage signals, not random schedules.

Usage-limit upsell

When a customer reaches 80% of their plan limit — messages, seats, API calls, storage — WhatsPortal sends a timely WhatsApp — 'You're close to your plan limit. Upgrade now to avoid interruption.' Includes the upgrade link.

  • When a customer reaches 80% of their plan limit
  • messages, seats, API calls, storage
  • WhatsPortal sends a timely WhatsApp
  • 'You're close to your plan limit

Feature-based upgrade prompt

When a customer uses a feature adjacent to a premium tier, send a contextual upsell — 'You've been using [Feature X]. [Feature Y] — available on the next plan — takes this to the next level. Upgrade for ₹[amount]/month.'

  • When a customer uses a feature adjacent to a premium tier, send a contextual upsell

  • [Feature Y]
  • available on the next plan

Annual plan upgrade campaign

For monthly plan customers at the 6-month mark, send a WhatsApp with the annual plan value proposition — 'Switch to annual and save ₹[X]. Equivalent to 2 months free.' Time-limited offers improve conversion.

Cross-sell for add-ons or connected products

When a customer's behaviour indicates readiness for a complementary product, send a personalised message — 'You're using [Product A] daily. Here's how [Product B] works alongside it.'

How it works

Streamlined automation in four simple steps.

  1. 01

    Define your upsell triggers

    Set usage thresholds and behaviour signals in WhatsPortal — 80% plan usage, feature X adoption, 6 months on monthly plan.

  2. 02

    Signals fire personalised WhatsApp messages

    When a customer's in-product behaviour matches a trigger, WhatsPortal sends the relevant upsell or cross-sell message automatically.

  3. 03

    Expansion MRR increases without outbound effort

    Customers upgrade based on relevant, timely prompts. Your CS team handles high-value upgrade conversations; automation handles the rest.

  4. 04

    Sync CRM & product database

    Qualified leads, ticket history, and NPS feedback are synced to HubSpot, Salesforce, or your product database.
