Installment offers and merchant settlement

Installment eligibility, payment schedules, merchant settlement, and refunds must stay synchronized. Partial returns can change both the customer obligation and merchant records.

Does the estimate cover credit risk and KYC

No. Credit policy, KYC/AML, disclosures, capital, collections, and consumer-credit rules require specialist review. This is a software estimate, not a financial-services launch budget.

Compliance and specialist costs

A fintech interface does not establish permission to provide financial services. Assess payment-data security, KYC/AML, licensing, and the responsibilities of your regulated partners. The calculator includes selected security engineering but excludes licensing, legal review, identity checks, and financial operations.

Superapp does not remove these responsibilities or guarantee compliance.

A cheaper way to start with Superapp

Build a focused version yourself before commissioning a full custom project. Superapp Pro is $25 a month; the subscription covers its plan allowance, while your time, extra usage, integrations, hosting, and specialist work remain part of the budget. A Superapp site is an alternative implementation, not a guarantee of WordPress or Shopify compatibility.

Sources and methodology

Rates are global marketplace benchmarks, not US-only agency quotes. Freelancer and agency ranges overlap because they describe different samples. WordPress.com Personal and Shopify Basic use annual billing, exclude introductory promotions and taxes, and replace the hosting budget. Feature hours and recurring budgets are our explicit planning assumptions.
