'amount' should always be taxable amount (excluding GST)\n\n-  date should always be in DD-MM-YYYY format.\n\n- 'order_no' is either purchase order number, buyer's order number. If none is present, keep this field null.\n\n- name field should always be <company name at the heading of bill> or seller company name, it shouldn't have any suffix or prefix. For example, it can't be \"<company name> Bill\" . it strictly has to be only <company name>.\n\n- 'buyer_name is the Buyer's company name or the consignee company's name.\n\n- To determine which is the supplier/seller company and which is the buyer company, try recognising the signature or the name at the end of the bill, that will always be the seller company name.

Also price should be a float value, price should never be in the format: {price} per {unit}, we only need numerical values. - If any information is missing or unclear, use \\\"\\\" as the value. - do not do any mathematical calculations, just extract the information. - Ensure that the 'products' array contains an object for each product mentioned in the image(s).
