WhatsApp Business API Pricing Comparison: 10 Providers Honestly Stacked Up (2026)

SendSeven Team, Editorial Team

What does the WhatsApp Business API really cost in 2026? A market comparison across 10 providers (SendSeven, 360dialog, Wati, Charles, Trengo, Respond.io, Superchat, Bird, Chatwerk, Chatarmin), current Meta list prices, a worked example for 3,000 messages, and 7 hidden costs nobody discloses upfront.

What does the WhatsApp Business API cost in 2026?

In 2026, the WhatsApp Business API costs between €9 and €349 per month in platform fees in Europe, depending on vendor and feature scope. Add to that the Meta list prices per message sent: €0.1131 for marketing messages in Germany, €0.0456 for utility and authentication; service messages inside the 24-hour customer service window are free. If you only need a BSP layer without UI (e.g., 360dialog or Meta Cloud API directly), entry pricing starts at €49/month. A full platform with inbox, campaigns and AI typically costs €79 to €199 at entry tier. Enterprise setups with dedicated support begin at €349 plus setup fees. SendSeven stands out with a base-fee model starting at €49/month for the full platform (or €9/channel/month for API Only), with no per-seat fees, no markup on Meta rates.

Research cutoff: May 2026. Meta list prices sourced directly from the official Meta pricing page. US and UK rates differ. See Meta's regional selector.

The two cost layers everyone conflates

Every WhatsApp Business API pricing conversation features two numbers. Conflate them and you'll compare vendors wrong.

Layer 1: Meta conversation fees

These fees come from Meta itself for every template message sent. They depend on recipient country and message category (marketing, utility, authentication, service). These costs are identical across vendors. Meta charges them whether you send via 360dialog, Bird, SendSeven or the Cloud API directly.

Layer 2: BSP or platform fees

These fees come from the vendor that sits between your application and Meta's infrastructure, known as the BSP (Business Solution Provider, now rebranded as Meta Business Partner) or the platform layered on top. This is where the price range lives. Some vendors pass Meta fees through without markup, others add 10–15 percent. Some charge per seat, others per channel, others stack a per-message markup on top.

If you compare two quotes looking only at Layer 2, the apparently cheaper vendor can end up more expensive at month-end because of a hidden markup on Layer 1.

Meta WhatsApp pricing April 2026: What changed

As of July 1, 2025, Meta no longer bills per 24-hour conversation but per delivered template message. Service messages inside the customer service window (24 hours after a customer message) are free. As of April 2026, the European rates are:

Important note for European customers: Germany is its own pricing region and costs over 2.3x more per marketing message (€0.1131) than Austria or Switzerland (€0.0490). A marketing broadcast to 5,000 German recipients costs €565.50 in Meta fees alone. The same broadcast to Austria: €245. US and UK marketing rates differ again. Meta's interactive selector shows the country-specific tariff.

Provider comparison: 10 platforms in a pricing check

The table below lists the ten platforms most relevant in the European market, with entry prices, per-seat and per-channel scaling, contract terms and trial options. Research was done directly on vendor websites in May 2026. Where a vendor doesn't publish pricing, that's noted, because absence of pricing is itself information.

n/a = not applicable · n/p = not public · As of May 2026, researched directly on vendor websites.

What the table doesn't directly show: four of the ten vendors don't publish complete pricing. Charles, Chatarmin, Bird and Wati either show no concrete numbers or only feature tables without monthly fixes. Want a quote? You'll go through a sales process first.

Six of ten vendors are headquartered in DACH: SendSeven in Augsburg, 360dialog, Superchat and Charles in Berlin, Chatwerk in Frankfurt, Chatarmin in Vienna. For GDPR-relevant setups, that's a relevant data point, because only two vendors explicitly advertise EU hosting on the pricing page: Chatwerk and SendSeven. Charles holds ISO 27001 but doesn't document it in the pricing context. Bird, Trengo, Wati and Respond.io stay silent on hosting location entirely.

Pricing models explained: why per-channel is different

Behind the numbers sit three fundamental billing models. Which one is cheapest for your business depends less on message volume than on your team and channel structure.

Per-seat (classic)

You pay per agent in the inbox. Examples: Superchat (€10/user), Trengo (€25–€50/user), Wati ($24–$69/user). Price scales linearly with team size. Pro: simple to calculate. Con: growth gets expensive. At 20 agents you quickly pay three or four times the entry price.

Per-channel (SendSeven API Only)

You pay per connected messaging channel, not per agent. SendSeven's developer-focused API Only tier charges €9/channel/month, with 1,000 messages per channel included before a €0.005 blended overage rate applies. Team size is not a billing factor: whether 3 or 50 agents work the inbox, the platform price stays the same. Pro: growth costs nothing. Con: the base fee adds up with many channels. SendSeven's full-suite plans (Basic, Professional, Scale, Enterprise) work differently: one flat base fee already includes every channel and a message bundle, with a single blended rate for usage beyond it.

Per-message markup (Twilio style)

You pay a markup on top of every Meta message. Bird does this, and partially Chatwerk (+10 % on Meta fees). It looks small but adds up: 10 percent on a DE marketing message (€0.1131) is €0.0113 extra. At 10,000 messages/month that's €113 in additional cost that doesn't show in the entry tier.

Hybrid models

Most vendors combine models: base tier + per-user add-on + additional number fee. Take Superchat: €79/month + €10/user + €49 per additional WhatsApp number + add-ons for analytics (€29), AI (€29), integrations (€49). With a 10-person team, 2 numbers and three add-ons you land at ~€286/month against the advertised €79.

Worked example: SMB with 3,000 messages / month

A typical European SMB sends about 3,000 WhatsApp messages per month, of which 70 % is marketing (newsletters, promotions), 30 % service replies inside the 24-hour window. Team: 3 agents. Region: Germany. Here's the math across five vendors.

Step 1: Meta cost (identical across all vendors)

Step 2: Platform fees (varies sharply)

Platform-fee math per vendor at 3,000 messages (70 % marketing / 30 % service mix): SendSeven Basic's €49 base fee includes 2,500 messages; the remaining 500 messages are billed at the €0.02 blended rate (€10), for a platform fee of €59. SendSeven API Only's €9/channel base fee includes 1,000 messages for the WhatsApp channel; the remaining 2,000 messages are billed at €0.005 each (€10), for a platform fee of €19. 360dialog charges €49/number without a platform UI. With Chatwerk, the €69 Starter plus 10 % markup on Meta fees (€23.75) adds to €92.75. Charles including the estimated markup lands at ~€385. Here are the totals per vendor:

Note: For SendSeven rows marked with *, the platform fee is the base fee plus overage beyond the included message bundle. SendSeven Basic includes 2,500 messages in its €49 base fee; SendSeven API Only includes 1,000 messages per channel in its €9/channel base fee. At 3,000 messages, both plans exceed their bundle, so the blended overage rate applies on top. Other vendors typically stack base tier and usage the same way. Some hidden caps (conversation limits, setup fees, markup levels) aren't publicly disclosed. Charles estimates are from a third-party analysis. SendSeven usage prices come from the official pricing page.

The spread at identical message volume: €256.51 (SendSeven API Only, developers only) to €622 (Charles incl. markup estimate). A €360+ monthly difference for exactly 3,000 messages to the same German recipients. If you need a full platform with UI and don't want to build your own, entry starts at around €287 (360dialog, no UI) or €297 (SendSeven Basic, with UI).

7 hidden costs no vendor discloses upfront

The pricing card is only the tip of the iceberg. Seven items to bring up actively in any sales conversation:

1. Setup and onboarding fees. Chatwerk invoices a one-time setup fee equal to the starter tier (€85 at Starter). Charles charges four-figure onboarding fees per third-party analyses. SendSeven, 360dialog and Respond.io: no setup fees.
2. Minimum contract term. Superchat locks in 12 months as standard. Charles typically 12–24 months. Trengo offers 20 % off for annual billing. SendSeven, Respond.io, 360dialog: monthly cancellation.
3. Markup on Meta fees. Chatwerk transparently discloses a 10 % markup. Charles per third-party analyses also adds markup (amount not officially stated). SendSeven, 360dialog and Chatarmin pass Meta fees through without surcharge.
4. Per-seat fees. Anyone scaling pays extra. Superchat €10/extra user, Trengo €25–€50, Wati $24–$69. SendSeven and Chatwerk Starter offer unlimited users (Chatwerk Starter caps at 3, then +€5/user).
5. Additional WhatsApp numbers. Multi-brand or multi-location setups get expensive: Superchat charges €49 per additional number, Chatwerk €45, 360dialog €49. SendSeven's full-suite plans include all 8 channels in the flat base fee (no per-channel surcharge); only the API Only tier bills per channel, at €9/channel.
6. Conversation or message caps in entry tiers. Trengo Boost (€349) only includes 500 conversations/month, each additional batch €15–€18. Respond.io Starter limits to 3 users with unlimited MACs; the Growth tier charges +$12 per 100 MACs. SendSeven has no conversation or contact caps.
7. Add-on costs for analytics, AI, integrations. Superchat ships analytics (€29), AI Copilot (€29) and integrations (€49) as paid add-ons. Adding all three: +€107/month. SendSeven includes analytics in every plan; AI assistants, chatbots and automation unlock from Professional up (not on Basic). Respond.io includes analytics and AI in every tier.

Which vendor for which company size?

The honest answer depends on three factors: team size, feature scope, and whether you need a UI or just an API.

You're a developer or agency who needs API only

Direct access to Meta's infrastructure without platform overhead. 360dialog (€49/number) or SendSeven API Only (€9/channel + €0.005/message beyond 1,000 included) are the most honest options here. Neither marks up Meta fees. SendSeven API Only additionally includes the REST API, webhooks, an analytics dashboard and widgets.

You're an SMB (1–10 agents, simple WhatsApp setup)

Here the competition is Superchat Basic (€79, 3 users, 12-month lock-in), Chatwerk Starter (€69/month annual + €85 setup, 10 % Meta markup) and SendSeven Basic (€49/month, unlimited users, no lock-in). The decision comes down to flexibility versus feature depth: Superchat has native iOS/Android apps, Chatwerk has EU hosting and markup transparency, SendSeven has no lock-in and unlimited users.

You're a growing mid-market business (10–50 agents)

Per-seat models get expensive. At 30 agents, Superchat already costs ~€370/month in seat add-ons alone. SendSeven Scale (€199/month) stays constant at any team size. Trengo Boost (€349) includes 10 users; each additional costs €25–€50. Respond.io Growth ($159/month) also scales per user.

You're enterprise with high volume and special requirements

This is where Charles, Chatarmin, Bird and SendSeven Enterprise land on the shortlist. Charles specialises in e-commerce enterprise with dedicated customer success. Chatarmin focuses on marketing performance without Meta markup. Bird offers global carrier integration (SMS, voice). SendSeven Enterprise (€499/month) has the lowest blended message rate among full-suite tiers (€0.01/message, one rate for service, AI, campaigns and SMS) and unlimited users. For even lower per-message pricing without UI, SendSeven API Only runs €0.005/message.

GDPR factor: premium for EU hosting?

For businesses with GDPR obligations, hosting location isn't a bonus, it's a prerequisite. Violations can cost up to 4 % of annual revenue (Art. 83 GDPR). The honest stocktake:

The main takeaway: EU hosting is standard at DACH vendors and not a premium add-on. SendSeven, 360dialog, Chatwerk and Superchat all include it in the entry tier. Wati and Respond.io lack explicit documentation. For regulated industries (healthcare, finance, public sector), that's a disqualifier.

Frequently asked questions

What does WhatsApp Business API cost per month?

The WhatsApp Business API costs between €49/month (pure BSP layer without UI, e.g. 360dialog) and €349+ (enterprise platforms like Charles or Trengo Boost) in 2026. For an SMB with 3,000 messages/month, total costs (platform + Meta fees) land between €286 and €622 monthly, depending on the vendor. SendSeven starts at €49/month (Basic) plus usage plus Meta list prices, or €9/channel/month for the developer-focused API Only tier.

Are Meta fees the same at every vendor?

Yes. Per-message Meta fees (e.g., €0.1131 for a DE marketing message) are identical at every vendor since Meta charges them regardless of the BSP. However: some vendors add a markup on top. Chatwerk discloses 10 % transparently; Charles allegedly does too per third-party analyses. SendSeven, 360dialog and Chatarmin pass Meta fees through without surcharge.

Do I need a WhatsApp BSP or is Meta Cloud API enough?

The Meta Cloud API is free up to 1,000 conversations/month, beyond which the same list prices apply. But: you get no inbox, no campaigns, no template management, no support. A BSP or platform delivers exactly that. If you're technically skilled and build everything yourself, you can use the Cloud API directly. For 95 % of businesses, a platform is the more predictable choice. More on this in the App vs API comparison.

Which is the cheapest WhatsApp Business API vendor in 2026?

By raw platform price: SendSeven API Only at €9/channel/month is the lowest entry price in the European market, though it ships without a ready-made UI. For a complete platform with inbox and campaigns, SendSeven Basic at €49/month is among the cheapest. 360dialog starts at €49/number but only delivers the BSP layer. Inbox and campaigns come separately. In the 3,000-message worked example, SendSeven API Only at €256.51 is the absolute low (developers only, no UI), followed by 360dialog at €286.51, then SendSeven Basic at €296.51 with full platform UI.

Is there a free WhatsApp Business API?

True zero-cost doesn't exist, since Meta charges its list prices to every vendor. But several vendors offer free trials. SendSeven 14 days with 100 test messages. Respond.io 7 days. Chatwerk 14 days. Superchat "free trial" without documented length. Charles offers no free trial.

Which vendor fits a European SMB best?

For a European SMB with 3–10 agents, multichannel ambition and growth perspective, the most honest options are SendSeven (unlimited users, no lock-in, EU hosting), Superchat (native apps, established in DACH) and Chatwerk (EU hosting in Frankfurt, transparent markup). Choice depends on whether you prioritise lock-in freedom, native apps, or hosting transparency.

What's a BSP and do I need one?

A BSP (Business Solution Provider, now rebranded as Meta Business Partner) is a Meta-certified partner who technically provisions the WhatsApp Business API for you. You can either go directly to the Meta Cloud API (technically demanding, no UI) or work with a BSP. Most platforms in this comparison (SendSeven, Superchat, Chatwerk, Charles, Wati, Trengo, Respond.io) are platforms on top of a BSP layer that add inbox, campaigns and templates. 360dialog is a pure BSP layer without UI.

What contract length is typical?

12 months is common in the European market (Superchat standard, Trengo annual). Charles typically uses 12–24-month contracts. Modern vendors offer monthly cancellation: SendSeven, 360dialog, Respond.io, Chatwerk. If you need flexibility (seasonal business, test setup), prioritise vendors without lock-in.

Conclusion

The WhatsApp Business API doesn't cost "X euros" in 2026. It almost always combines Meta list prices and platform fees. Platform fees vary by a factor of 7: €49 for a pure BSP layer to €349 in a mid-market entry tier. At identical message volume, what matters less is the advertised entry price and more: is there a markup on Meta fees, how does the price scale with team size and channel variety, are there lock-in periods, and is pricing publicly documented at all?

Three vendors don't publish full pricing (Charles, Chatarmin, Bird). One uses a 12-month lock-in as standard (Superchat). Two add a markup on Meta fees (Chatwerk, Charles per third-party analyses). Selection gets easier when you define your own size and feature needs first, then exclude vendors who don't transparently meet those requirements.
