Backend
Laravel 12 on Octane, a double-entry ledger, and 2,000+ automated tests.
Web
Dashboards for companies and admins.
Mobile
The employee app to request pay early and receive it.
Business input
Input to the owners on decisions that shape the product.
03 The hard part03 / 05
One payout, one transfer
Each payout is locked while it’s being processed and sent with a unique reference. Before any retry, the system asks the payment provider whether the earlier transfer already went through.
Every rupiah recorded on two sides
Every movement of funds is booked on two sides that must balance exactly. If they don’t, the system refuses to record it. Entries are never edited afterwards; fixes go in as a new reversing entry.
Send the same payout signal twice.
A simulation with example numbers (Rp 3,000,000 a month ÷ 30 days = Rp 100,000 a day). It shows what happens when the same payout signal arrives more than once, like a retried job or a duplicated webhook. Not real data.
