WhatsApp Business API pricing has two parts: Meta charges you per message template you send, priced by template category and by your customer's country, and your provider charges a monthly platform subscription. There is no licence fee for the API itself. Most businesses find the platform subscription, not the messages, is the larger number.

The reason this feels harder than it is: three variables move at once, and most pricing pages explain one of them.

The three variables

Template category. Marketing, utility and authentication are priced differently. Marketing costs the most.

Your customer's country. Rates are set by where the recipient is, not where you are. A UK business messaging South African customers pays South African rates.

Your monthly volume. Utility and authentication rates step down as volume rises. Marketing does not.

Get those three straight and the rest is arithmetic.

Per-message rates

Rates effective 1 July 2026, per message, in GBP:

The same rates in South African rand:

Two observations worth acting on. UK marketing messaging costs nearly three times UK utility messaging. And South African utility messaging is around a third of the UK rate, which makes South Africa a notably cheap market to run high-volume operational messaging into.

Volume tiers

Utility and authentication rates reduce as monthly volume rises, in steps of 5%, 10%, 15%, 20% and 25% at increasing thresholds. Marketing rates do not tier at any volume.

The practical consequence: a business sending high volumes of operational messages sees its effective rate fall meaningfully below list, while a business sending mostly promotions pays list price forever. If your messaging is growing, growth is cheaper on the utility side than the marketing side, and that should shape what you build first.

What template categories actually mean

Category is not a label you choose freely. Meta reviews every template and rejects miscategorised ones.

Utility covers messages tied to a specific transaction or request the customer has already made. Order confirmations, delivery updates, appointment reminders, payment receipts.

Authentication covers one-time passcodes and verification.

Marketing covers anything promotional, and anything that does not clearly fit the other two. Offers, product news, re-engagement, abandoned basket messages.

The grey area is the expensive one. A message that reads as helpful to you may read as promotional to a reviewer, and it will be priced as marketing. Writing templates that sit clearly inside utility is one of the few genuine levers on your bill.

Platform subscription

You cannot access the Platform directly, so a provider subscription is unavoidable. Most price on monthly active contacts, meaning unique people you exchange messages with in a month, rather than message volume.

Cue's published pricing:

Bands are set at 1,500, 5,000 and 10,000 monthly active contacts. Additional WhatsApp numbers and integrations are £49 a month each. AI resolutions are £1.49 on pay as you go, £0.99 in a 100 bundle and £0.89 at 1,000. Connect carries a one-off £249 onboarding fee; Automate and Scale include onboarding.

When comparing providers, check three things: how monthly active contacts are counted, whether seats are charged separately, and what happens when you exceed your band. Per-seat pricing is where costs escalate fastest for a growing team.

A worked monthly bill

A UK retailer, 4,000 monthly active contacts, sending order and delivery updates with a weekly promotion.

Messages are 21% of the bill. The platform is 79%. Volume tiers would reduce the utility line further.

This ratio is the useful takeaway. Optimising message spend saves tens of pounds. Choosing the wrong platform, or paying per seat as your team grows, costs hundreds.

South Africa

The model is identical. What changes is the rate card and the currency you are billed in. South African per-message rates are materially lower than UK rates across every category, so a South African operation sending the same volume pays substantially less to Meta while paying the same platform subscription. The platform share of the bill is therefore even higher.

Cue is GDPR and POPIA compliant, which matters for South African operations handling customer conversation data.

Before you commit

Work out your monthly active contacts before you look at any pricing page. It is the number every provider bands on, most businesses guess it, and guessing it wrong is how people end up on the wrong plan.

If you are still deciding whether you need the Platform at all, is WhatsApp Business free covers the free app and where it stops, and WhatsApp Business API vs the Business app covers the difference directly.
