The Billing page on the Pro plan, with the plan status, renewal date, payment card and next charge, the Change plan, Update payment method, Manage billing and Cancel subscription buttons, and the billing history
Use Settings → Billing to upgrade from the free trial, change or cancel your Flowella plan, update your payment method and download invoices. Flowella takes payment through Stripe: you enter card details in Stripe, and Flowella never stores them. This page covers your Flowella subscription only. Meta bills WhatsApp message fees separately, on your own Meta account. See Pricing and categories. For what each plan includes, see Plans and limits.

Who manages billing

Everyone in your organisation can open Settings → Billing and use every action on it, whatever their role. When you invite someone in Settings → Team, the helper text under Role describes what each role is for: At the moment, any member can also upgrade, change or cancel the plan and update the payment method, whatever their role. Agree in your team who looks after the subscription. See Team members and roles.

What the Billing page shows

The page changes with your plan. The Current Plan panel at the top is always there. Below it you see either the plan cards (on the free trial or the Free plan) or your subscription details (on a paid plan).

Current plan panel

The panel shows your plan name, such as Free trial, Free, Starter, Pro or Enterprise, with a badge when one applies: The Free plan has no badge.

Plan cards on the free trial or Free plan

On the free trial or the Free plan, the page shows Upgrade your plan with four cards. Use the Monthly and Yearly buttons above the cards to switch the prices shown. A billable WhatsApp message is one that WhatsApp marks as chargeable. Each one counts as one unit of your Flowella allowance. Starter and Pro prices load from Stripe for the interval you pick, so the card shows what Stripe Checkout charges. When a plan includes messages, the price reads Starting at an amount. Below it, the card shows how many units are included and the price of each additional unit. You only add a card when you choose a paid plan.
On the Free plan you can still sign in, see your data and receive incoming messages, but you cannot send WhatsApp messages. Upgrade to Starter or Pro to send.

Subscription details on a paid plan

On Starter, Pro or Enterprise, the panel adds Billing details:
  • The payment method on file, for example a card brand and its last four digits
  • The Next charge amount and date
  • A note when metered usage, such as overage, is billed on top of the recurring amount
Beside it are the subscription buttons: Change plan, Update payment method and Cancel subscription open Stripe in the same tab and bring you back to Settings → Billing when you finish. Under the panel, Billing history lists your last 12 invoices with Date, Invoice, Amount and Status. In the Download column, select PDF to download an invoice or View to open it in Stripe. Older invoices are in the Stripe customer portal under Manage billing.

Upgrade to a paid plan

1

Open Billing

Go to Settings → Billing. During the trial you can also select Upgrade now in the banner at the top of the app.
2

Choose monthly or yearly billing

Select Monthly or Yearly above the plan cards. The Starter and Pro prices change to match.
3

Pick a plan

Select Upgrade to Starter or Upgrade to Pro. For Enterprise, select Contact sales to talk to the Flowella team instead.
4

Complete Stripe Checkout

Stripe Checkout opens with your email address, and your phone number if your profile has one, already filled in. Enter your card details and billing address. Stripe needs the address to calculate tax. You can also enter a promotion code.
5

Return to Flowella

When the payment succeeds, Stripe returns you to Settings → Billing, which shows a confirmation and updates within a few seconds. If you leave Checkout without paying, the page tells you that checkout was cancelled and your plan has not changed.
To check it worked, look at the Current Plan panel. It shows Starter or Pro with an Active badge, and your subscription details replace the plan cards. Upgrading during the trial ends the trial straight away. Your allowance starts counting from the day you subscribe. See Plans and limits.

Subscription states

This diagram shows how an organisation moves between the free trial, a paid plan and the Free plan.

When sending is blocked

When the trial ends, a payment has been past due for more than 7 days or you are on the Free plan, Flowella blocks these actions:
  • Replies, templates and Smart replies sent from the Flowella inbox
  • Test Template sends and Bulk sends, including Resend unsent
  • Create WA Flow and Sync WA Flow on the Flows page, which turn a HubSpot form into a WhatsApp Flow
  • Send WhatsApp Template steps in HubSpot workflows
  • Through the Flowella API: sending messages, sending templates, recording opt-outs, and creating, editing, submitting or test-sending templates
If you reach the 5,000-message cap before the trial ends, Flowella blocks further sends until you upgrade. This covers sends from the inbox (including replies and Smart replies), bulk sends and messages sent through the API. In the app, a blocked action opens a dialog titled Subscription required, Payment required or Message limit reached. Select View plans & usage to open Settings → Billing. In HubSpot, a Send WhatsApp Template step fails with a message that your subscription is not active or that your payment is past due. The API returns 402 with the code PAYMENT_REQUIRED for a past-due payment, or 403 with the code FORBIDDEN when there is no active subscription. Actions locked by billing shows the exact messages. You can still sign in, view your contacts, conversations and templates, open Results, receive incoming messages, create and edit templates in the app, connect WhatsApp numbers and HubSpot, add opt-outs on the Opt-outs page and open Settings → Billing. Nothing is deleted when sending is blocked: your contacts, conversations, opt-outs, templates and settings stay as they are.

When a payment fails

When Stripe cannot take a payment, everyone in your organisation gets a Payment failed notification in the app and by email. The Billing page shows a Payment failed badge. Sending keeps working for 7 days. To fix it:
  1. Go to Settings → Billing.
  2. Select Update payment method and enter a working card.
  3. When Stripe next takes the payment successfully, the badge changes back to Active.
If the payment is not fixed within 7 days, sending stops until a payment succeeds.

Troubleshooting

Contact Flowella support. The warning means Flowella cannot report your billable messages to Stripe correctly.
Billing is not set up for your workspace yet. Contact Flowella support to arrange your subscription.
Flowella shows “Could not start checkout” when Stripe Checkout cannot start. Try again, and contact support if it keeps failing.
The page checks Stripe every few seconds after you return from Checkout. If your new plan does not appear within a few minutes, reload the page, then contact support with your Stripe receipt.
