Perhaps you might try St. Petersburg with hara. It will be time consuming. There should be other terms like ṛṇa that I do not remember immediately. These terms are taught in primary class arithmetic meaning denominator and minus. alābhaḥ  and  anucchedaḥ mean no profit and no loss respectively.

There is a paper in Sanskrit ’Vārtāśāstrīyaṃ  kiñcit’   by Vibhūti Bhūṣaṇa Bhaṭṭācārya on the accounting system and market management in Kauṭilya’s Arthaśāstra published in the Sārasavatī suṣamā VS 2006 and 2007. The concepts come into discussion. One may disagree on some points but the paper is informative and innovative. But I read it in the seventies and cannot accurately tell everything.
