Recommended Alguna Setup

1. Create transaction-based products

   Navigate to Products → Add Product

   • Create a metered product for “Payment Processing”
   • Set pricing as percentage (2.9%) + fixed fee ($0.30)
   • Create tiered pricing for volume discounts
2. Set up usage metering

   Navigate to Billable Metrics → Create Metric

   • Metric: “Transaction Volume” — Sum of transaction amounts
   • Metric: “Transaction Count” — Count of transactions
   • This tracks total payment volume for percentage-based billing
3. Configure monthly settlement

   • Bill monthly in arrears (after transactions occur)
   • Generate detailed statements showing transaction counts and volumes
   • Support net settlement (fees deducted from payouts) or gross billing
4. Build volume-based tiers

   Create pricing tiers that reward growth:

   • $0 -$50K/month: 2.9% + $0.30
   • $50K -$250K/month: 2.5% + $0.25
   • $250K+/month: 2.2$0.20
5. Set up partner revenue sharing

   For BaaS/embedded finance: track interchange revenue and automate the 70/30 split with banking partners using separate invoices or credits.
