Hi Product Hunt — I'm Suhas, and I build AccBrain at BETH TECHNOLOGIES. TallyPrime runs a large share of small-business accounting outside the US — India, the Gulf, East Africa, South and Southeast Asia. It is a good product and it is a desktop application, which means the books live on exactly one computer. Answering "who owes me the most?" means walking to that computer, or phoning whoever is sitting at it. We wanted those books answerable from a phone, in plain language. The obvious build is to stuff the ledgers into a prompt and let the model answer. We didn't, for one reason: an accounting figure that is 3% wrong is worse than no figure at all. So the model never does the arithmetic. It picks a tool. Each tool is a registered query against a local SQLite mirror of the books, and it returns exactly the number the matching report on screen would show — receivables aging, cash position, P&L, balance sheet, stock, cost centres. The answer and the report run the same code path, so they cannot disagree. A question that maps to no tool gets "not applicable" rather than something plausible. The other half was getting data out of Tally at all. A small Windows agent reads the company over TallyPrime's own XML gateway — no plugins, no licence change — and pushes to Postgres behind row-level security. The phone pulls that into a local mirror and computes every figure itself, so reports open with the accounting PC switched off. Sync is incremental and keyset-paginated on (updated_at, key), because the agent batch-inserts and thousands of rows share one timestamp — a plain "updated_at >" cursor silently skips rows, which is the worst possible failure mode for an accounting mirror. It is read-only by default; writing back queues a command that the desktop agent posts into Tally, in Tally's own voucher numbering series. What it is not: it does not do your bookkeeping, and it is not running a model on your phone. The conversation, the search index and the narration vectors stay on the device — but answering a question does send the tool's output to a model service. That seemed worth saying plainly rather than hiding behind "private by design". Free tier keeps the dashboard. A licence is a one-time 1, 3 or 5-year term rather than a subscription, covering one desktop and any number of phones. Android today. Happy to go deep on any of it — the tool-calling layer, the sync cursor, or why it turns out Tally exposes no per-godown closing balance at all and we had to derive it from openings plus movements. Ask away.
