Beyond Basic Buttons:
Custom Payment Workflows

Most off-the-shelf plugins only handle basic checkouts. At Emerald Soft, we engineer robust payment architectures designed for complex business rules, automation, and scale.

Custom Checkouts & Subscriptions

Seamlessly collect payments directly on your website or app. From tiered SaaS subscriptions to complex multi-item cart calculations, we build frictionless checkout experiences.

API & Webhook Automation

Stop manually updating invoices. We use webhooks to instantly sync payment data with your CRM, trigger welcome emails, or update accounting software like Xero/QuickBooks upon successful charges.

Dynamic Calculations & Fees

Need to pass on transaction fees? Split payments between multiple vendors? Or calculate dynamic shipping/tax based on geolocation? We handle the complex math before hitting the gateway.

Compliance & Fraud Protection

We ensure your implementations are PCI-compliant, utilizing secure tokenization and 3D Secure 2.0 to protect against fraud without compromising conversion rates.
