Auditing Inventory at Vendor Premises
Material sent out for job work is your stock sitting on somebody else's floor. Custody has moved; ownership has not, and that single fact governs everything that follows. The balance sheet still carries it because the risks and rewards never transferred, and no sale took place when the lorry left. The same logic runs the other way for the job worker, whose premises hold goods that must never appear in his own inventory. Verification establishes three things. That the quantity the challan says went out is the quantity actually lying at the vendor, allowing for what has been consumed and what has been returned. That the processing loss claimed is consistent with the process and with what other vendors on the same work report. And that nothing has been counted twice, which is the recurring failure here, because material in transit at a cut-off can appear on both sides of the same reconciliation without anybody intending it.
Material You Own but Do Not Hold
Material sent out for processing creates a position that is entirely ordinary and consistently misrecorded. The principal sends inputs to a processor for a defined operation: machining, plating, dyeing, packing, or any step the principal does not perform. The goods leave the premises and the ownership does not move with them, because no sale has taken place and the risks and rewards remain where they were. Ownership retained through the process is the governing fact. The processor holds the goods as a bailee, may work on them only as instructed, and must return them or the output made from them. Nothing about the arrangement transfers title, so the processor cannot treat the material as stock and cannot deal with it as their own. Where it sits in the books follows from that. The material remains an asset of the principal and is disclosed as inventory held at a third party, which is a presentation matter as well as a recognition one, because a lender or an auditor needs to know that part of the reported stock is not on the premises. The processor records it in memorandum records rather than in inventory.
The GST Documentation Trail
Under GST the movement is documented rather than invoiced, and the documents are what evidence the position. Goods sent for job work travel under a delivery challan issued by the principal, carrying the description, quantity, value and the details of both parties, and the challan is the primary record that the goods left without being supplied. An e-way bill accompanies it where the consignment value crosses the threshold, which independently corroborates the movement. Return timelines carry a real consequence. Inputs must be received back within the period prescribed, and capital goods within their own longer period, and where they are not returned within the applicable period the transaction is treated as a supply on the day the goods were originally sent out, with tax payable accordingly. That is why an aged job work balance is a tax exposure and not merely a reconciliation item. Records the processor must maintain complete the trail. The job worker keeps an account of the goods received, processed and returned, and where the principal has declared the processor's premises as an additional place of business the position changes again, so the arrangement's formal structure has to be established before the balance can be interpreted.
Counting at a Vendor Site
Verifying material at a processor's premises is a count on somebody else's floor, and the practical constraints follow from that. Right of access and notice should come from the job work agreement rather than from goodwill. An agreement providing for verification on reasonable notice removes the awkward conversation entirely; without it, a reluctant processor has a straightforward reason to decline, and a balance that cannot be verified has to be reported as such. Segregating your material from the vendor's own is the first task on arrival and it is frequently the hardest. A processor working for several principals holds physically similar material for each, and where nothing on the floor distinguishes them the count relies on the processor's own records, which is precisely the thing being tested. Material consumed, in process and returned are counted as three separate populations rather than as a single balance. Inputs still awaiting work, material part-processed, finished output awaiting despatch and scrap generated all have different quantities and different values, and a reconciliation that treats the whole balance as undifferentiated stock cannot test the process loss, which is where the differences usually are.
Evidence That Supports the Balance
A job work balance is supported by three things, and a confirmation on its own is the weakest of them. Vendor confirmation states what the processor says is lying at his premises, and it is a useful starting point precisely because it comes from the party with the goods, but it is a representation rather than verification. Where the balance is material or long outstanding, it is tested by physical count at the vendor's premises, which is the only evidence that the goods exist. The second support is the reconciliation of issue, consumption and return: material sent out, less material consumed in producing what came back, less material returned unprocessed, should equal the balance claimed. Each element is evidenced from the challans in both directions rather than from a summary. The third is process loss measured against its normal range for the operation. Every process loses material, and the allowance is agreed in advance, so the test is whether the loss claimed sits inside it. Loss consistently at the top of the range, or rising without a change in the process, is a finding.
Getting Job Work Stock Verified
Select vendors by value and by age of balance, not by convenience. The largest balances need verification because of what they are worth; the oldest need it because age is the strongest indicator that something has gone unreconciled, and a balance outstanding for several processing cycles is rarely still physically present in the quantity claimed. A vendor holding a small balance for two months is a lower priority than one holding a modest balance for two years. The job work agreement should permit the visit, and this is worth fixing before it is needed. An agreement that provides for access to the processor's premises for verification, on reasonable notice, removes the awkward conversation entirely, and its absence gives a reluctant vendor a reason to refuse. The agreement should also state the processing loss allowance and the period within which material is returned. Independent verification is required where the balance is material to your accounts, where a lender has charge over the stock, or where the vendor's own confirmations have been inconsistent, and auditing auto component stock covers vendor premises within the same cut-off as the plant.
