Nidhi Traces is batch and expiry tracking software for Indian distributors, at ₹399/month with unlimited users. Record the lot when goods arrive, ship first-expired-first-out automatically, see every lot expiring inside your window, and name every customer who received a bad batch in one recall report.
If you distribute medicines, packaged food, cosmetics or anything else that carries a lot number and a use-by date, "how much do I hold" is not enough — you need to know which lot, whose lot, and how long it has left. Nidhi Traces adds that layer on top of the stock you already record in Nidhi Inventory. Every delivery becomes a lot with a supplier lot number, a manufacture date and an expiry date; the expiring list shows what is running out of shelf life; outbound stock is allocated first-expired-first-out so the oldest sellable goods leave first; and when a supplier issues a recall, the forward trace turns a lot number into a list of customers with phone numbers and invoice numbers. Available on the 399apps cloud or self-hosted.
Best for
Pharma & medical distributors · Food and FMCG wholesalers · Cosmetics & personal-care distributors · Agri-input and seed dealers
Works across
Pharmaceuticals · Food & beverage · FMCG · Cosmetics · Wholesale & distribution
Each delivery is recorded as a lot with your own lot number, the supplier's lot number printed on the carton, and the manufacture, received and expiry dates. Lot numbers are unique per item, so two products can both carry the supplier's "L-2026-01" without colliding.
One screen of every lot you still hold that expires on or before a date you choose — item, lot, expiry, days left and quantity on hand. Lots with no expiry never clutter it. This is the list a distributor works down every week.
Outbound stock is allocated first-expired-first-out automatically: earliest expiry first, undated lots last, ties broken by receipt date then lot code. A short allocation is refused outright rather than posting movements that do not add up.
A lot is open, quarantined, recalled or closed. Only an open lot allocates — the moment you quarantine one, automatic picking skips it and a manual pick of it is refused, rather than waiting for someone to tell the pickers.
Enter a lot number and get who to contact: customer, phone, email, invoice numbers and quantity held, plus everything that left by a route other than a sale. The report reconciles received against issued plus on-hand and says so out loud when the two disagree, instead of showing a short customer list you would trust.
Scan the sticker or serial on the goods, or type the invoice number a customer is complaining about, and get the lot it came out of — plus the supplier, the purchase order and the day it arrived.
One page per lot for a buyer's compliance desk: item, your lot number, the supplier lot number, manufacture, expiry and received dates, current status, your GSTIN, and every receipt that fed the lot.
Lot and expiry tracking matters enormously to some businesses and not at all to others. Read this before you add the app.
You are legally required to trace a lot
If you run a pharmaceutical, food, FMCG or cosmetics distribution business, lot and expiry are not optional record-keeping — a recall has to name the customers who received the goods. That is what the forward trace produces.
Expiry write-offs are a real cost line
If stock reaches its use-by date at the back of the shed because nobody picks it first, FEFO allocation is the fix: the earliest-expiring sellable lot leaves first by default, not by discipline.
Your buyers ask for paperwork per lot
If hospital, institutional or export buyers want a document stating where a consignment came from and when it expires, the batch certificate is one PDF per lot.
Nothing you sell expires
A hardware shop, an auto-parts dealer or a garment store rarely needs a lot layer. Nidhi Inventory alone tracks stock, warehouses and barcodes at ₹399/month — do not pay for Traces to leave the expiry field blank.
You only need bins, not lots
If your question is "which shelf is it on" rather than "which delivery was it", that is Nidhi Warehouse, a different ₹399 app. The two are independent — you can own either without the other.
You want full pharma ERP with a drug licence register
Traces covers lots, expiry, FEFO, recall and certificates. Schedule-H registers, narcotic registers and drug-licence workflows are not in it. If those are hard requirements, a dedicated pharmacy ERP such as Marg ERP will fit you better today.
Heads-up. Nidhi Traces reads the stock ledger and purchase-order receipts that Nidhi Inventory records, so the two run together — ₹399 + ₹399 = ₹798/month with unlimited users. It has no dependency on Nidhi Warehouse.
