Dr = Cr, forever
An immutable ledger
Nothing is ever edited or deleted. A wrong entry is corrected by a reversal that posts alongside the original, so the history stays complete and every balance can be traced back to its lines.
Double-entry bookkeeping for any business
Profit you can prove.
AktaBook keeps any business’s books on a double-entry ledger that is immutable, always balanced, and reported live in four financial statements — and if you trade inventory-like assets, every sale is costed at weighted average automatically.
From service companies to retail to asset trading — one set of provable books.

Why the numbers hold up
Built on accounting truth
Three rules the ledger never breaks — they are what make the reports worth trusting.
COGS = qty × avg cost
A WAC engine you can read
Every sale is costed at the weighted average of what you actually paid for the asset. You preview the full journal — cost of goods sold included — before a single line is posted.
WIB · whole Rp
WIB days, whole rupiah
Business days follow Jakarta time and every amount in the books is an integer rupiah. No timezone drift at midnight, no rounding residue hiding in the statements.
How it works
From a day of trading to statements, in three steps
The daily routine is preview-first: you always see the full journal before it becomes part of the books.
01
Enter the day
Record the day’s buys, sells, and expenses once — quantities and rupiah, no journal knowledge needed.
02
Preview the journal
The app drafts every debit and credit, WAC cost included, and shows it balanced before anything is written.
03
Post & report
One confirmation posts the entry to the immutable ledger, and all four statements reflect it immediately.
