BigCommerce Implementation Overview

The Paystand BigCommerce App allows you to accept digital payments, directly within your BigCommerce storefront:

• ACH
• Bank Transfers
• Credit Cards

This app integrates seamlessly into your checkout process and can optionally connect with NetSuite for automated reconciliation.

Requirements to Implement 

To successfully implement the Paystand BigCommerce App, you’ll need the following:

Technical Requirements:

• BigCommerce Version: Stencil theme, v2+ API support
• Paystand Account: Active account with API credentials and dashboard access
• NetSuite Account (optional): Required for ERP reconciliation
• Developer or Agency Partner: To install and configure the app (manual installation)
• Manual Installation: Paystand does not install or host your BigCommerce store

Important

• Paystand does not install or host your BigCommerce store. A developer or agency partner is required for manual setup and configuration.

Technical Implementation

Checkout Flow

All merchants follow the base flow below:

1. Customer Checkout Begins – A Checkout Object is created in BigCommerce (/v3/checkouts).

2. Paystand Checkout Renders – The embedded modal collects payment data and creates a Paystand Payment Object.

3. Payment Success – Paystand returns a confirmation to BigCommerce.

4. Webhook Event – Paystand sends payment confirmation to the app via /webhook/transactions.

Important considerations

• Merchants using NetSuite benefit from automatic reconciliation and payment mapping between systems.
• Merchants without NetSuite manage all reconciliation directly in BigCommerce.
• Ensure your Paystand API credentials are live before enabling checkout in production.

Merchants Without NetSuite

BigCommerce finalizes the order locally.
The app updates the order (PUT /v2/orders/{orderId}) and marks it as Awaiting Fulfillment.

Merchants With NetSuite

BigCommerce pushes the order to NetSuite via your connector or iPaaS integration.
NetSuite then:

• Creates a Sales Order and Payment record,
• Applies the deposit automatically,
• Uses Paystand paymentId and orderId for reconciliation mapping.

ERP Integration API

For customers using NetSuite, reconciliation uses the following API endpoint:

POST URL
https://api.paystand.com/v3/netsuites/apply-payment/public

Required Fields in Request Body

{
 "paymentId": "{{paymentId}}",
 "transactionId": {{transactionId}},
 "transactionType": "invoice" | "salesOrder"
}

• The paymentId comes from Paystand’s webhook payload.
• The transactionId is the internal NetSuite ID (Invoice or Sales Order).
• The payment amount must not exceed the invoice balance.
• The target record must exist in NetSuite before payment is cleared.

Tips

• Test API connectivity in a sandbox environment before linking live payment data to NetSuite.
• Confirm that paymentId and transactionId match between Paystand and NetSuite before applying payments.
• Monitor webhook logs to ensure successful payment event delivery.
