What is WhatsApp BSP (Solution Partner)?
A WhatsApp BSP, which Meta now calls a Solution Partner, is a Meta Business Partner that gives other businesses access to the WhatsApp Business Platform and can bill them for API usage through its own credit line.
What it means for your business
The practical difference from a Tech Provider is billing: with a Solution Partner you can pay one invoice that includes Meta's message charges; with a Tech Provider you add your own card and Meta bills you directly.
Either way the message rates are Meta's. Ask any provider whether it adds a markup on top of them.
