Deklara
Customs documentsPreview
Who it is for
Importers, exporters, customs brokers (PPJK) and bonded-zone companies that prepare BC documents for CEISA 4.0.
Mistakes in a BC document often show up only after it is rejected, and fixing them takes time.
What it does
- Prepares BC 2.3, 2.5, 2.6.1, 2.6.2, 2.7, 3.0 and 4.0 documents through step-by-step forms.
- Checks each document against the DJBC schema and rules, including the duty and tax calculations.
- Reads line items from Excel files.

Lunasa
Bookkeeping and inventoryAvailable
Who it is for
Small and medium businesses that need a correct general ledger and stock cards.
When sales, purchases and stock are recorded separately, financial statements are hard to trust and slow to produce.
What it does
- Records sales and purchases with PPN (VAT) and PPh withholding.
- Keeps stock cards per warehouse with FIFO or average costing.
- Builds the general ledger and financial statements from the same transactions.
