Billing and plans

Understand OonoBox pricing, plans, add-ons, and how billing works.

What's a conversation?

A conversation is a thread between you and one customer over one channel. All the messages back and forth in that thread count as the one conversation, no matter how many are sent.

Your monthly usage is the number of new conversation threads started during the current calendar month.

Plans show a "conversations/month" limit. On every plan this is a soft limit: you're nudged to upgrade as you approach it, but you're not blocked.

Add-ons

Need more capacity? Add-ons extend your plan without changing tiers:

Extra seats

  • Price — $7/month per seat (or $70/year).
  • What it adds — One additional team member slot.
  • Example — On the Starter plan (3 seats), buy 2 extra seats to have 5 total.

Extra WhatsApp numbers

  • Price — $10/month per number (or $100/year).
  • What it adds — One additional connected WhatsApp number.
  • Example — On the Growth plan (5 numbers included), buy 2 extra to manage 7 numbers.

Extra conversations

  • Price — $15/month per 1,000 conversations (or $150/year).
  • What it adds — 1,000 additional monthly conversation allowance.
  • Example — On the Starter plan (1,000 included), buy 2 blocks to get 3,000 total.

How add-ons work

  • Co-terminus — Add-ons share your plan's renewal date. If your annual plan renews in 6 months, new add-ons renew with it.
  • Pro-rating — If you buy mid-cycle, you're charged only for the remaining days in your billing period.
  • Stacking — Buy as many add-on units as you need. No limit.

Upgrading and downgrading

Upgrading (e.g. Starter to Growth):

  1. Go to Settings → Billing → Plans.
  2. Click Upgrade.
  3. Choose your billing period (monthly or annual).
  4. Confirm payment.

You're charged the difference immediately, and the new plan takes effect right away.

Downgrading (e.g. Growth to Starter):

  1. Go to Settings → Billing → Plans.
  2. Click Downgrade.
  3. Select the lower tier.
  4. The change takes effect at the end of your current billing period (no refund for the downgrade).

You keep your current features until the period ends, then the new plan limits kick in.

Billing period

Choose monthly (renews every 30 days) or annual (renews every 365 days).

  • Annual is cheaper — about 2 months free vs. paying monthly.
  • Choose your period before checkout. You can change it at renewal.

Payment methods

OonoBox accepts:

  • Credit/debit cards — Processed through Stripe.
  • Local payment methods — Pesepay (for Zimbabwe), including mobile money such as EcoCash and local cards.

Payments are processed securely. Your billing is sent to your email after each renewal.

Invoices

View invoices and download receipts:

  1. Go to Settings → Billing → Invoices.
  2. Click an invoice to download the PDF.

Keep invoices for your records and accounting.

Overages and soft limits

Conversation limits are soft on every plan. We meter your usage and nudge you as you approach the limit, but we don't block you from sending.

  • Free plan — Soft limit of 50 conversations/month.
  • Starter plan — Soft limit of 1,000 conversations/month.
  • Growth and Pro — Unlimited conversations.

If you consistently exceed your limit, consider buying extra conversation add-ons or upgrading.

Annual discount

Troubleshooting

"Payment declined" — Check your card details, expiration, and that you have sufficient funds. Try a different card or contact your bank.

"Can't upgrade" — Ensure you have a valid payment method on file. Contact support if the issue persists.

"Invoice missing" — Invoices are emailed to your account email after payment. Check spam folder or download from Billing > Invoices.

"Want a refund?" — Open a support ticket from the in-app Help menu. We evaluate refund requests case by case.

"Billing date changes" — Your renewal date is the same day of the month you subscribed. If you subscribed on the 31st, annual renewals happen on the last day of each year.
