Turn SaaS trials into paid customers. Activation nudges on WhatsApp.

Help new trials reach the key action, check in once they’re active, and send your own checkout link only when they choose a plan. Every answer lands in HubSpot, so sales sees who is ready.

Step through the play as the trial user.

Marcus is ten days into a trial of Acme Analytics. Each step shows what he sees on WhatsApp and what lands on his HubSpot record, from the check-in to his checkout or a call. Your answers in the Flow decide the branch. All but the owner are custom properties the play creates.

    The trial-to-paid blueprint.

    A welcome on day 0, help for quiet trials, then a check-in for active ones and one branch: ready buyers get your checkout and the rest get a person. You build it in a HubSpot workflow, from Flowella’s WhatsApp triggers and actions.

      Your product writes the trial

      Flowella reads HubSpot. Write the trial, its end date and the key action to the contact.

    2. Send WhatsApp TemplateThe welcome, on day 0

      The trial length and the one thing to try first.

    3. BranchHas trial_activated fired by day 3?

      No: setup help and a Breeze Customer Agent. Yes: on to day 10.

      Gate on a real signal

      Ask an inactive trial to pay and it burns goodwill. Help it reach the key action first.

    4. DelayUntil day 10

      A pricing visit or a WhatsApp question can start the check-in sooner.

    5. Send WhatsApp TemplateThe check-in

      trial_checkin, with the Flow button “Choose what’s next”.

      Say what happens to their work

      The question behind an upgrade is often whether their work survives. Answer it first.

    6. Delay until event happensForm Completed, up to 2 days

      The answers land as trial_next_step, plan_interest and trial_feedback.

      No answer in 2 days: the owner gets a task.

    Three WhatsApp templates and the Flow they open carry the check-in, and the day-0 welcome follows the same style. Each one reads well on a phone, and every variable comes from the HubSpot record.

    Five things that show a trial is ready to pay.

    The play captures all five, and each lands in HubSpot as something a workflow can read, not a hunch about who will convert.

    Why trial nudges on WhatsApp work.

    A stalled trial rarely tells you why. WhatsApp gives each one a direct line from sign-up to the key action, to help, and to a plan.

    • Why trials stall

      People sign up with intent and lose it before they reach the moment that proves the product. A message in the chat they already use brings them back while there’s still time.

    • How to enhance it

      Trigger on product events your app writes to HubSpot, route team accounts to sales, assign a Breeze Customer Agent to setup questions, and map the end date as a text property.

    • Gotchas

      Don’t message every login, stop the moment the plan is paid, keep hard selling out of week one, and map dates as text: a raw date property arrives as 20.10.2026 00:00.

    The point: trials convert when people reach value before the clock runs out.
