# GyaanByte Labs

**Accounting data-migration automation — reconciled to $0 variance.**

We migrate US small businesses between accounting systems — QuickBooks Desktop → QuickBooks Online, Sage 50 / Sage Intacct → QBO, plus NetSuite, Dynamics, and Zoho data workstreams. 6+ production migrations, 200,000+ records, every one reconciled to zero variance.

We build the automation behind that service — and publish the reusable parts openly, starting with the **first chart-of-accounts mapping resources on the Hub**:

- 📊 [`coa-mapping-synthetic`](https://huggingface.co/datasets/gyaanbyte/coa-mapping-synthetic) — **v1 released:** 1,162 synthetic COA-mapping rows (QuickBooks Desktop / Sage 50 → QBO) with the COA-Map-Bench v1 benchmark split.
- 🤖 [`coa-mapper`](https://huggingface.co/gyaanbyte/coa-mapper) — **v1 released:** 33M-param mapper fine-tuned on it — **acc@1 0.883** on COA-Map-Bench v1, beating TF-IDF (0.745), zero-shot bge-small (0.796) and zero-shot qwen3:8b (0.788).
