Return to vendor: getting credit for defective and unsellable supplier stock
Return to vendor done properly — when RTV applies, how to get a return authorization, the claim email that works, and how to count the stock.
InventoryX is in development and not available today. ClearStock is the live Shopify app.
Return to vendor (RTV) means sending stock back to your supplier — defective units, goods damaged before you received them, expired or dated product, or inventory the supplier contractually takes back — and recovering value as a credit, a replacement, or a refund. It's the opposite direction of a customer return: this is you, the buyer, enforcing the deal. The mechanics matter because RTV is where small stores leak money silently — defective units get shelved "to deal with later," the later never comes, and the supplier never hears about the problem until you've also re-ordered the same defective batch.
This article covers the RTV process end to end: when it applies, how to request authorization, the claim email structure, and the count discipline. What happens to units customers send back — including whether a returned unit should route to RTV — is decided in the returned inventory processing framework; this article picks up where that decision table points at the supplier.
When RTV actually applies
Not every bad unit deserves a claim. RTV makes sense in four situations:
| Situation | Typical supplier obligation | Worth pursuing when |
|---|---|---|
| Defective units discovered at receiving or shortly after | Replacement or credit under defect/warranty terms | The unit has meaningful wholesale value and the defect rate exceeds what you'd absorb |
| Goods damaged in inbound transit | Credit or replacement (carrier claim may apply first) | You photographed the damage at receiving — evidence is the whole game |
| Expiring or dated goods (food, cosmetics, supplements) | Credit per freshness guarantee, if your terms include one | You negotiated a freshness clause — without one, you're asking a favor |
| Contractual buyback (unsold seasonal stock, discontinued lines) | Per the agreement | The contract exists in writing; verbal buyback promises rarely survive |
The filter in the last column is the honest one. A $4.50-wholesale bath bomb with a dented tin is not worth an email chain — absorb it, adjust the count, and watch the SKU's defect rate. A $38-wholesale aquarium filter with a failed pump across six units is a claim, and a supplier-quality conversation. If the same supplier shows up on your worst-defect list quarter after quarter, that's the pattern your supplier scorecard should be catching before you keep re-ordering.
Step one: the return authorization, not a surprise box
Never ship anything back without written authorization. Suppliers routinely refuse unauthorized returns — the package sits in their receiving area unclaimed, and you've paid freight to donate stock. The sequence:
- Document before you move anything. Count the defective units, photograph them (the defect visible, plus the batch or lot code if printed), and pull the original PO number — the PO correspondence guide covers keeping that paper trail intact from order to claim. If the defect only shows in use — a camping stove whose igniter fails on the third click — a 15-second video is worth more than five photos.
- Request an RMA (return merchandise authorization) in writing. Email, not a phone call. You need the supplier's return address, their RMA number, and their stated remedy — credit, replacement, or refund — before the box moves.
- Ship with the RMA number on the label and inside the box. The units leave your count when they leave your building, not when the credit arrives.
- Track the credit. If the remedy was a credit against your account, apply it to your next payment or next PO within the same month. Aging credits die quietly.
The documentation habit is the same one that protects you at freight-claim time: evidence taken at the moment of discovery, not reconstructed from memory three weeks later. If your receiving team logs damage with photos as a standing step in your quality control inspection, the RTV email writes itself.
The claim email, annotated
Here's an RTV request with the anatomy marked. Note what it does not do — no throat-clearing, no anger, no paragraph of history.
Subject: RTV request — 6 units, AQUA-FILT-300 — INV-2027-118, defect video attached
Hi Wen,
Receiving on March 3 (PO INV-2027-118, 24 units AQUA-FILT-300) we found 6 units with pumps that fail to prime — video attached, defect starts at 0:12. Lot code on all six: F3-0112.
Why this opening works: PO number in the first line, defect described as an observable behavior, evidence attached before any request. The supplier's QC person can verify without asking you a single follow-up question.
We'd like to return these 6 units for replacement. Our ship-to is below; please confirm an RMA number and whether replacement units ship with our next order or separately.
The remedy is stated, not begged for. "With our next order" is a real option worth offering — suppliers approve replacements faster when freight is folded into an existing shipment.
The remaining 18 units are testing fine and are already on shelves, so this is isolated to lot F3-0112 as far as we can tell — flagging it in case other buyers received the same lot.
This line is diplomacy that pays: it tells the supplier you're not claiming the whole shipment, and it gives them a batch-level heads-up they can act on. Suppliers remember buyers who make their QC easier.
Thanks — Dana
Total length: under 120 words. Every RTV email needs the same five elements: PO reference, SKU and quantity, observable defect description, evidence, requested remedy.
The count discipline: when stock leaves your books
RTV creates a small accounting-timing trap. The unit is physically gone when the box ships, but the credit arrives later — and if you wait for the credit to adjust your inventory, your Shopify count is carrying phantom stock for weeks.
The rule: adjust the count down the day the RTV box ships, recorded as an inventory adjustment with a reason like "RTV INV-2027-118 — awaiting credit." The credit is a receivable, not inventory. When the supplier sends replacement units, they come in through receiving like any other stock; when they issue a credit instead, it lands in your accounts payable conversation, not your stock counts.
Track one number per SKU while a claim is open: units shipped but not yet credited or replaced. If that number is still nonzero after 60 days, the claim is dead — escalate once, then stop spending time on it and let the scorecard remember.
When RTV isn't the move
Two honest alternatives to a claim, and when each wins:
- Negotiate a discount instead of returning. For defects where the goods are still sellable at a markdown — a misprinted cap logo, slightly off-color embroidery kits — a 30–40% supplier credit with you keeping and discounting the stock often beats a round-trip freight bill on low-value goods. You need real defect counts and photos either way.
- Absorb and track. Below a value threshold you set yourself (many operators use roughly the cost of 30 minutes of admin time per claim), don't claim. But keep the defect tally per supplier — the tally is what turns "this supplier seems flaky" into a number when you're re-negotiating terms or qualifying a second source.
One boundary worth stating plainly: RTV is your claim on suppliers, not on customers. If a customer's returned unit turned out to be defective, the customer side is already handled — refund, exchange, or restock decision — under your returns process. Whether that unit then joins an RTV batch is a routing decision covered in the returned inventory decision table, and the unit's condition at inspection determines whether it's even claim-worthy.
Common questions
What does return to vendor mean? Return to vendor (RTV) is sending stock back to your supplier under warranty, defect, damage, freshness, or contractual buyback terms, and recovering value as a credit, replacement, or refund. It's a buyer-side claim, distinct from customer returns, which flow through your own refund process.
How do I get a return authorization from a supplier? Email with the PO number, SKU, quantity, an observable defect description, and photo or video evidence attached; request an RMA number and their stated remedy in writing. Ship only after you have the RMA, with the number on the label. Unauthorized returns frequently go unclaimed at the supplier's dock.
Do I adjust inventory when I ship RTV goods or when the credit arrives? When the goods ship. The units are gone from your building at that moment, so the count should reflect it — record the adjustment with a reason referencing the RMA or PO. The pending credit is money owed to you, not stock you own.
When is RTV not worth it? When the units' wholesale value is low relative to the freight and admin time a claim costs, or when a discount-and-keep arrangement recovers more value than a return. Set a dollar threshold per claim, absorb below it, but keep a defect tally per supplier so the pattern shows up in your scorecard.
What if the supplier ignores the claim? Escalate once in writing with a deadline, then stop investing time. Deduct the credited amount from future payments only if your terms clearly allow it and you've said so in writing — otherwise the dispute belongs in your supplier evaluation, not in unilateral payment holds that sour a working relationship.
Next step
Open your last three months of inventory adjustments and search for vague reasons like "damaged" or "defective." Total the units and dollars behind them. If the number surprises you, pick the biggest SKU on the list, check whether its supplier terms cover defects, and send the first claim email this week — the template above, five elements, under 120 words.
