+# Dukaan Saathi — Receipt Parser (Llama-3.2-3B fine-tune)
+
+Fine-tuned **Llama-3.2-3B-Instruct** for structured receipt parsing in Indian kirana (convenience) store workflows.
+
+Part of the [Dukaan Saathi](https://huggingface.co/spaces/summerdevlin46/dukaan-saathi) inventory copilot demo.
+
+## What it does
+
+Takes noisy supplier receipt OCR text and returns a structured JSON object with line items, quantities, prices, and supplier info. Designed for messy real-world receipts: handwritten bills, printed tax invoices, informal tally notes.
+
+## Training data
+
+- 6 hand-authored examples from real kirana receipt formats
+- 22 Modal LLM-generated synthetic examples augmenting edge cases
+- Total: 28 examples; training focuses on format consistency over broad generalisation
+
+## Example
+
+**Input:**
+```
+MAHALAKSHMI MARKETING
+No. 2816  Date: 27/5/26
+Parle  1 X 2450 = 2450
+Bingo(C)  4 X 870 = 3480
+Subtotal 5930  Discount 612  Total 6542
+```
+
+**Output:**
+```json
+{
+  "supplier": "Mahalakshmi Marketing",
+  "invoice_no": "2816",
+  "date": "2026-05-27",
+  "items": [
+    {"product_raw": "Parle", "qty_cases": 1, "qty_units": 1, "unit_cost": 2450.0, "total": 2450.0},
+    {"product_raw": "Bingo(C)", "qty_cases": 4, "qty_units": 4, "unit_cost": 870.0, "total": 3480.0}
+  ],
+  "subtotal": 5930.0,
+  "discount": 612.0,
+  "gst": 0.0,
+  "net_total": 6542.0
+}
+```
+
+## Inference
+
+```python
+from huggingface_hub import InferenceClient
+
+client = InferenceClient()
+prompt = """### Instruction:
+You are a receipt parser for an Indian convenience store. Extract all line items. Return ONLY valid JSON, no markdown.
+
+### Input:
+<paste receipt text here>
+
+### Response:
+"""
+result = client.text_generation(prompt, model="summerdevlin46/dukaan-saathi-receipt-lora", max_new_tokens=768)
+```
+
+## Limitations
+
+- Small training set; overfits to known receipt styles (Mahalakshmi Marketing, Sri Venkateshwara Marketing, Brundavan Buns)
+- Owner approval gate always required before any inventory write
+- Not a general-purpose receipt parser
