Document Management
lim provides document management that complies with Japan’s Electronic Bookkeeping Act (電子帳簿保存法 / 電帳法), which requires businesses to store and manage electronic records properly.
Electronic Bookkeeping Act Overview
Since January 2024, all businesses receiving electronic transaction data (invoices, receipts via email/web) must store them electronically with:
Searchability — by date, amount, and counterparty
Timestamping — proof that the document existed at a specific time
Tamper prevention — documents cannot be altered after storage
Retention — 7 years minimum (10 years for some)
lim handles all four requirements automatically. Upload your documents and lim takes care of
compliance.

# Search by date range
lim docs search --from 2026-03-01 --to 2026-03-31
# Search by amount range
lim docs search --min 10000 --max 50000
# Combine search criteria

Timestamping
lim timestamps every document on upload with a cryptographic hash. This proves the document existed at the recorded time and has not been modified.
# Verify a document's timestamp
lim docs verify doc_01KG...
✅ Document verified
Original hash: sha256:a1b2c3d4...
Current hash: sha256:a1b2c3d4...
Timestamp: 2026-03-16T10:30:00+09:00
Integrity: intact ✓
Documents cannot be deleted or modified once uploaded. This is by design — the Electronic
Bookkeeping Act requires tamper-proof storage. If a document was uploaded in error, mark it as
void instead.
