The challenge

The client's payouts platform handles every step from sale completion to final settlement for a global seller community, with near-zero error tolerance given its financial and regulatory sensitivity.

What the system had to handle

  • Multiple payout models: scheduled, same-day or instant, and tax-initiated
  • Diverse rails: bank accounts, cards, third-party payout providers and in-platform balances
  • High-volume background processing for calculations, ledgers and notifications
  • Consistent, predictable behavior under peak load

Our role

An embedded engineering team inside the client's payouts engineering organization.

Four initiatives as an embedded team
01

Core payouts platform

Built

Asynchronous pipelines for payout computation and execution; fee, adjustment and timing rules; retry, reconciliation and failure handling

  • Accurate payout status for sellers
  • Background jobs scaled independently of marketplace traffic
02

Regulatory incident handling

Problem

Bank requests for information paused payouts and relied on slow, manual workflows

Built

Automated ingestion of bank files, a state-driven incident lifecycle with auto-clearance, and automated seller banners

  • Faster seller notification
  • Fewer support tickets
03

Self-service finance reporting

Problem

Finance relied on manual file transfers from engineering

Built

Payout aggregation by payment processor, a dedicated reporting store, filtered S3 files and availability alerts

  • Faster month- and quarter-end close
  • Higher accuracy
04

Payout investigation portal

Problem

Ops needed to investigate payout issues without production access

Built

Search by seller, payout and date; statuses and bank responses; compliance view; masked processor logs

  • Faster issue resolution
  • Complete audit trails
