Why it matters
A business in Africa uses Paystack while a business in Europe uses Stripe. Both call the same endpoints, receive the same response formats, and manage subscriptions with identical code. Conjoin handles the provider differences.
Add a payment form to your checkout page in minutes. Send card details and amount to the charge endpoint. Payment confirmed, receipt emailed, and transaction recorded in your dashboard.
Let customers upgrade from the $29 price to the $99 price mid-cycle. Call the update subscription endpoint with the new price ID. Proration calculated automatically, card charged for the difference, and billing date stays the same.
Customer card fails on renewal day. Conjoin Billing retries after 1 day, 3 days, and 7 days with email notifications at each step. Card updated by day 5, subscription continues without manual intervention.
Built for Your Workflow
Charge customers with a single API call that handles payment intents, card validation, 3D Secure authentication, and receipt generation. The response confirms payment status and provides a hosted receipt URL.
Ship checkout in minutes, not weeks of payment gateway integration.
Pause a subscription to stop billing while keeping the customer relationship intact. No charges occur during the pause. When the customer returns, resume billing without requiring them to re-subscribe or re-enter payment details.
Retain customers through pauses instead of losing them to cancellations.
Update a subscription with a new price ID and Conjoin calculates the prorated amount based on time remaining in the billing cycle. Customers are charged the difference immediately or credited on their next invoice, depending on your configuration.
Customers switch plans mid-cycle with correct charges applied automatically, no billing code needed.
Configure dunning schedules that retry failed charges at intervals you define. Pre-dunning emails alert customers before card expiry, and payment failure notifications prompt them to update their details before subscriptions lapse.
Recover 15-30% of failed payments through automatic retries without building reminder email systems.
