The challenge

Indonesian online sellers juggle Tokopedia, Shopee and TikTok Shop fees, withholding tax and e-Faktur filing across several dashboards.

What we built

  • Live command-center dashboard across marketplaces
  • Tax ledger with e-Faktur batch export
  • Inventory reconciliation and an ad pilot that pauses keywords on low return
  • Profit calculator for sellers

Under the hood

  • Multi-tenant data model with precise money fields
  • Digitally signed e-Faktur XML batches; key cleared from memory after use
  • Webhook queue and background workers

Stack

  • Next.js 15
  • TypeScript
  • Express 5
  • Prisma
  • PostgreSQL
  • BullMQ
