The problem
A hotel buys from dozens of suppliers every week: vegetables, dairy, meat, groceries, LPG, linen laundry, housekeeping supplies and maintenance contracts. Bills arrive as GST invoices, delivery challans and handwritten market slips, and accounts match them by hand to purchase orders and the store receiving register before paying.
Rates that creep
Vegetable and dairy rates are agreed weekly, but invoices arrive at different rates and nobody compares every line.
Billed versus received
Short deliveries, rejected items and weight differences recorded at the receiving bay are not always deducted from the invoice.
Handwritten and mixed formats
Local suppliers send handwritten bills and challans that are typed into Tally line by line.
Duplicates and GST errors
The same bill is submitted twice, or tax is charged as IGST instead of CGST and SGST, which affects input tax credit.
What we build
We build an invoice pipeline for hotel purchasing. Invoices, challans and market slips arrive by email, as WhatsApp photos or as scans from the store. OCR and a large language model extract supplier, GSTIN, invoice number, line items, quantities, units, rates and tax. Each line is matched to the purchase order or indent, the store receiving entry and the agreed rate list for that week. The pipeline checks arithmetic, tax type and GSTIN format, and looks for duplicates. Matched invoices are prepared for posting to your accounting system, and mismatches go to an exception queue with the reason and the source document side by side.

FAQs
01Can it read handwritten bills from local vendors?
Yes, for reasonably clear handwriting on typical market slips. Lines it reads with low confidence are flagged for review, and the pilot reports accuracy separately for handwritten bills.
02Does it work with Tally?
Yes. We usually produce an import file or use Tally's integration options to create purchase entries, with a link to the bill image stored for reference. Systems such as Zoho Books or SAP Business One connect through their APIs.
03What if we do not raise purchase orders for daily vegetables?
Many hotels buy daily produce against a kitchen indent and a weekly rate list. The pipeline can match against the indent, the receiving entry and the rate list instead of a PO.
04Can it help with food cost control?
It produces clean, item-level purchase data by supplier and category, which feeds food cost reports. It does not replace stock counts or recipe costing, but it makes the purchase side reliable.
