There is no pricing page, no rate card, no merchant discount rate, no per-transaction fee schedule and no tier table anywhere on momo.vn, business.momo.vn or developers.momo.vn — the 212-URL developer sitemap contains no pricing route, and the merchant portal is a login-gated single-page app. Commercial terms are set during the MoMo for Business (M4B) merchant onboarding and review process, which is a contact-and-verify motion: register a merchant profile, integrate on test, complete UAT, get the account verified, then request production credentials. A buyer cannot price a MoMo integration before entering that process. This is recorded as plan_count: 0 rather than omitted, because a documented absence of published pricing is the finding. pricing_model_observed: type: negotiated-merchant-agreement evidence: >- MoMo's onboarding documentation gates production access behind account verification and a MoMo-side review; no self-serve checkout or plan selector exists. free_surfaces: - name: Business Page note: >- MoMo's Business Page getting-started page offers a Business Page "mien phi" (free) and routes acquisition through a hotline (1900 636 652) and merchant.care@momo.vn rather than a signup flow. source: https://developers.momo.vn/v3/docs/business-page/start/ plans: []
