An embedded checkout keeps payment interaction within the store experience. A hosted checkout sends the buyer to a provider’s payment page. In a CRM, the workflow usually starts from an invoice or charge. This choice shapes the screens, return flow and payment monitoring. The portfolio includes Mercado Pago transparent checkout, Inter Pix, Woovi/OpenPix and InfinitePay hosted checkout. It also covers PayPal integration based on a third-party plugin and customization of an acquired Asaas module for Perfex CRM. Each case explains its implementation and acceptance-testing status. ### Connecting payment status to the right order Creating a charge is only one step. Your system must also associate the transaction with the correct order, handle pending states and follow confirmation. A browser return or a customer click alone does not replace confirmation from the payment provider. The scope can include webhooks, status queries, repeated notification handling, reconciliation rules and customer messages. These are defined around the selected API and existing architecture; providers do not all expose the same capabilities. ### What to include in a quote request Share your platform and version, preferred provider, payment methods and current problem. Explain whether you need an integration installed, an existing module adapted or a new workflow developed. Please do not include API keys or passwords in the initial message. A proposal can cover code review, environment setup, development, acceptance checks and deployment guidance. Gateway accounts, fees, account availability and provider approvals are handled directly with the relevant provider. ### Frequently asked questions Can you integrate any payment provider? Feasibility depends on the documentation, API, account permissions and target system. Tell us which provider you use and the intended workflow so we can assess the requirements. Do you test before going live? The proposal defines the validation scenarios. Where a provider offers a sandbox, we use it for the agreed flows and coordinate the production activation step. Does integration change fees or guarantee payment approval? No. Fees, risk assessment and transaction approval depend on the provider and account. The service covers the technical implementation and agreed behavior. Quoted individually ### Let’s understand your project. A useful solution starts with your workflow.
