What is your provider's markup actually costing you?
Most WhatsApp Business API providers bill you Meta's per-message charge plus their own margin: usually 15–25%, billed through their platform so you never see the split. Enter your monthly message volume below to see the two halves separately. Nothing is stored, and you don't need an account.
Why Klaros can't mark this up even if we wanted to.
You connect your own WhatsApp Business Account and your own Meta billing. Meta charges you directly; we are never in the payment path. That isn't a pricing promise we could revise later: it's a consequence of the architecture. We charge a flat licence and nothing per message. See pricing →
How this is calculated
Meta bills per message, at a rate that depends on the destination country and the category of the message. We multiply your volume by Meta's published rate for the market you picked, then apply the markup percentage you selected to show what a reseller would add on top.
Since October 1, 2026, replies are billed too
Meta now charges for messages sent inside an open 24-hour conversation: replies to a customer who wrote first, and utility templates sent in that window. A reply costs the destination country's utility rate, with no volume tiers. Enter your replies above and the estimate prices them. Each WhatsApp number's first 1,000 replies a month are counted as free: Meta's partners report this allowance, and we have not yet seen it on our own billing. Because Klaros operates on a 0% markup model, you pay that rate directly with no vendor surcharge. Resellers adding 15 to 25% markups will apply those margins to every customer reply.

These rates were derived from real WhatsApp billing, not a published list, but they are still an estimate, not a quote. Your own invoice depends on your exact message mix and any agreement you hold with Meta. Once you're sending through Klaros, the in-app cost dashboard replaces this estimate with your real billed figures: computed by the same code that produced the numbers above. The reconciliation behind those figures, and the defects it caught in our own billing, is in this build note.
