Overview

TS Accounting is the general ledger that will connect with TS HRM + EWA and TS LMS (automatic journals planned), and a bookkeeping product in its own right for companies in Cambodia and Japan. It keeps the journal, the trial balance, monthly movements and the general ledger, and closes months and years with balances carried forward.

The rules that keep the books trustworthy are enforced by the database itself, not only by the application, so they hold even if a screen or an integration makes a mistake.

Main features

Journal and closingTransfer slips, journal, trial balance, monthly movements and general ledger. Month close and reopen; year-end close with carry-forward by partner and currency.
Tax returns for each country (currently Cambodia)GDT monthly tax on salary, withholding tax and VAT, in US dollars and riel at the recorded NBC rate.
Bank statementsABA statement PDFs imported and checked line by line. Rules turn lines into entries; a line can be split, for example into principal and interest.
Moving from your current softwareImport your current chart of accounts with its tax rates, bring opening balances from a trial balance, and run both systems side by side, reconciled account by account.
Charts for each countryChart of accounts and tax codes from Cambodian and Japanese templates. Switch over at the start of a year or mid-year; earlier months stay locked.
One sign-in with TS HRMOpened from TS HRM without signing in again. A REST API with roles and OpenAPI for other systems. Screens in English and Japanese.

Rules the books keep

Enforced by the database. Automated tests try to break each one on every change.

  • L1Every posted entry balances.
  • L2A posted entry is never changed or deleted; corrections are reversing entries.
  • L3Nothing is posted into a period that is not open.
  • L4An entry is reversed at most once.
  • L5A closed fiscal year never opens again.
  • L6The audit log can only be added to.
  • L7Each company's data is separated at row level.
  • #Posted entries are linked in a hash chain, so any change after the fact shows.
