Invite by email
Send someone a signup link instead of handing them a temporary password directly. Links expire after 7 days.
Every invitation below is generated as a link only. Nothing is emailed automatically until an administrator configures SMTP for this server — share each link with its recipient directly.

Flagged conflicts

Usage
What people use, from the usage events (no names, ids or amounts are ever recorded). Last 30 days.
SRO review
Every SRO file we loaded, with its tables. Set the rate once per table, then approve. Only approved tables reach customers.
Data gaps
Missing pieces we know about, and who we asked.
Real bills
Real assessed bills with every identifier removed, replayed through the engine. For checking our arithmetic and defaults only.
CPC list
The FY2026-27 customs procedure codes with the SRO each one points to. Read-only. Errors in the book are shown as printed.
Review queue
One place for everything that needs your look (new, from the 2026-10-23 reread). Each item shows the page it comes from. Accept it, correct it (say the right reading), or reject it. Items that affect the calculator come first.
Rate readings
Rates read from the SRO page images, with the HS lines they would give. Admin only. Every line is VERIFY and none is used for a customer until you approve.
Laws
Acts, rules, policies and orders as searchable text. Admin only until you approve. English files use the file's own text; Bangla files are read by OCR: VERIFY against the gazette.
HS finder
One HS code, every source we hold for it. Admin only. Everything except the tariff line is read by machine from the files: VERIFY.
Source files
Every file downloaded from the official SRO site, compared with the SROs we loaded. Laws, rules and circulars are listed here too.
Audit log
Admin actions across the app, newest first. Shows the last 200 recorded.
