What A Returns SLA Should Actually Commit To, Clause By Clause

A returns SLA should commit to five things: when the clock starts, how fast inspection happens after arrival, what disposition decision each grade triggers, which cases are excluded, and how performance gets reported. Anything vaguer than that cannot be enforced, measured, or used to defend an account health case.

• An SLA clause is enforceable only if it names a start event, a finish condition, an owner and a remedy.
• A cross-border return has separate legs, and one blended number hides the leg where time is actually lost.
• A warehouse can only be held to the leg it controls, which begins at the receiving scan.
• Exception categories belong in the agreement in advance, not in an email sent after the first breach.
• Percentile reporting exposes the slow tail that monthly averages smooth away.

Why Do Most Returns SLAs Fail the First Time They Are Tested?

They describe intentions instead of naming a start event, a finish condition, an owner and a consequence.

A returns SLA fails when it is written as reassurance rather than as an obligation. Lines such as 'returns are processed promptly' or 'sellable inventory is restocked quickly' read well in a proposal and mean nothing during a disagreement, because neither side can point to the moment the obligation started or the moment it was missed. Test every clause with three questions. What event starts the clock? What exactly has to be finished before it stops? Who owns the miss, and what happens then? A clause that cannot answer all three is decoration, and you will discover that on the day you need it most. The second failure mode is scope confusion. A cross-border return is not one event. The buyer ships to a domestic address inside Mexico, the parcel moves to the receiving warehouse, the warehouse inspects and grades it, a disposition decision is made, and the unit either goes back into sellable stock or leaves the operation. One blended 'returns turnaround' number covering all of that hides the leg where the delay actually lives. When your reported number gets worse, you will not know whether to talk to the carrier, the warehouse, or your own team that never answered the disposition email. The third failure mode is the missing exception list. Every operation has cases it cannot process on the standard path: parcels with no label reference, items that arrive wet or crushed, units that need a serial check against your records. An agreement written as if these do not exist gets breached in the first month, and once both parties are used to breaches, no clause in the document is enforceable anymore. The fourth is measurement. If the two sides pull the numbers from different systems and neither definition is written down, every review meeting becomes an argument about the data rather than about the operation. Agree on the source, the field, and the timestamp before you agree on the target. For sellers on Amazon Mexico there is a further reason to get this right. The marketplace evaluates the seller account, not the warehouse behind it. A vague clause does not shield you from a buyer complaint about a refund that took too long, so the SLA has to be written to protect the metric that is actually at risk: yours.

Which Clock Should a Returns SLA Start On?

Start the warehouse clock at the receiving scan, and measure the earlier legs as separate, separately owned commitments.

There are three candidate start events, and choosing the wrong one makes the whole agreement unusable. The first candidate is the moment the buyer requests a return. This is the number your customer experiences, so it belongs in your own internal reporting, but no warehouse can be held to it. Between the request and the arrival sit the buyer's own delay, the label download, the drop-off, and the carrier's line haul. The second is the first carrier scan. This is a genuine improvement, because it proves the parcel entered the network, but it still measures a party that is not in the room when you sign. The third is physical receipt at the warehouse door, evidenced by a timestamped scan. This is the only start event the receiving party fully controls, so it is the one the processing clause should use. Everything upstream still needs a home: put transit visibility in its own clause with its own owner, so a slow carrier does not silently become a warehouse problem, and a slow warehouse cannot hide behind a carrier. Once the start event is agreed, write down the definitions that arguments are actually made of. Does 'received' mean the trailer arrived, or the parcel was scanned into the returns queue? For a pallet of consolidated returns, does the clock start on the pallet or on each unit inside it? Is the target measured in calendar days or business days? What is the daily cutoff, and what happens to a parcel that lands after it? The holiday calendar deserves its own line. A team operating across Laredo and Monterrey works against two different sets of public holidays, and an agreement that says 'business days' without naming which calendar applies will produce a dispute in the first long weekend of the year. Finally, require the evidence to be exportable. A start event that only exists inside someone else's dashboard is not evidence. Ask for the receiving timestamp as a field you can pull into your own records, joined to the return reference, so that when a marketplace or a buyer asks you to prove when the item arrived, you can answer from your own data rather than by opening a support ticket and waiting.

What Should the Inspection and Disposition Clause Say?

It should name the grades, the test that assigns each grade, the default action per grade, and who can override the default.

The inspection clause is where most agreements go quiet, and it is the clause that decides how much of your money comes back. Start by writing the grading scheme yourself. The warehouse executes the test, but only you know what your buyer will accept. A practical scheme names four states: sellable as new, sellable with new packaging, needs repair or refurbishment, and not sellable. Each grade needs an objective test that a warehouse operator can apply in seconds without calling you: seal intact, all listed accessories present, no cosmetic damage visible on the faces the customer sees, powers on where applicable. Then name the default action attached to each grade. Sellable as new goes straight back into available stock with no email to you. Sellable with new packaging goes into a repack queue with your supplied materials. Needs repair goes to a hold location and waits for your instruction. Not sellable goes to a quarantine location with an aging rule so it does not become a permanent tenant of your rack space. Without defaults, every single return becomes a decision, and decisions cost more than the units are worth. Evidence requirements come next. Specify which grades trigger photographs, how many, and of what: the shipping label, the outer box condition, the item itself, and any visible defect. Specify serial or lot capture for categories where you need it. Specify that the buyer-declared reason and the inspector-observed condition are recorded as two separate fields, because the gap between them is the most useful data your returns operation produces. Call out the categories that never rejoin sellable stock regardless of appearance. Personal care items, anything with a broken hygiene seal, food contact goods, and products where safety depends on an unbroken package should be written into the clause by category, not decided case by case on the floor. Where a category sits under specific Mexican consumer protection or product regulation, get the rule confirmed by a qualified specialist and then write the confirmed rule into the agreement, rather than leaving it to the judgment of whoever opens the box. Last, add the override path. Name who on your side can change a default disposition, how that instruction is delivered, and how long the warehouse will hold a unit while waiting for it before the aging rule takes over.

How Should Exceptions and Carve-Outs Be Written?

List the categories that leave the standard path in advance, and give each one its own handling route and its own reported timeline.

An SLA with no carve-outs is a promise to breach. The goal is not to shrink the commitment until it is meaningless; it is to make the standard path honest and to route the rest somewhere visible. Write each exception as a named category with three attributes: how it is identified, what happens to it, and how it is reported. The categories worth naming in a cross-border returns operation are consistent. Unidentifiable arrivals come first. A parcel with no return reference, an illegible label, or contents that do not match any open return cannot be processed on the standard clock. The clause should say how long the warehouse investigates, what information it sends you, and what happens if you do not respond. Wrong-item returns are next. A buyer who ships back something that is not yours, or ships two orders in one box, breaks the one-to-one assumption every returns system is built on. Decide in advance whether these are photographed and held, or photographed and returned to the buyer at your cost. Transit damage needs its own route because it involves a third party. If a claim has to be filed, the unit is evidence and cannot be repacked or disposed of until the claim closes. Say who files, who holds, and for how long. Restricted and regulated categories belong in a separate list: items with lithium batteries, aerosols, anything with a safety or labeling rule attached to it. Confirm the handling requirements with a qualified specialist for each category you sell, and write the confirmed handling into the agreement rather than discovering the rule when a parcel is already on the dock. High-value units deserve a dual-control clause: two people present at opening, video or photo record, and a separate secure location. Two more clauses are worth insisting on. First, a peak season provision that states in advance how volumes above an agreed baseline are handled, so neither side improvises during the busiest weeks of the year. Second, a dependency clause: when the delay is caused by missing information from your side, such as an unanswered disposition request, that time is excluded from the warehouse clock and reported separately. That clause protects the vendor, which is exactly why it makes the rest of the agreement credible.

How Do You Measure Whether the SLA Is Being Met?

Report per-leg cycle times as distributions with exception counts alongside, and never accept a single monthly average as the whole picture.

An SLA you cannot audit is a preference. Reporting is what turns it into an operating agreement, so the reporting clause deserves as much attention as the targets. Ask for per-leg cycle times, not one number. At minimum: request to arrival, arrival to inspection complete, inspection to disposition executed, and disposition to available for sale. Each leg has a different owner and a different fix, and only a per-leg view tells you which conversation to have. Ask for distributions instead of averages. An average is dominated by the easy majority of returns and hides the slow tail, and the slow tail is what generates buyer complaints. Percentiles show you what your unluckiest customers actually experienced. If the median looks healthy and the upper percentile is far away from it, you do not have a speed problem, you have an exception problem. Exceptions get their own report. Count them, code them by reason, and trend the codes. A rising count of unidentifiable arrivals usually means your return instructions to buyers need rewriting, not that the warehouse got slower. A rising count of wrong-item returns often points at a listing that shows the wrong variant image. Define the data contract explicitly: which fields are delivered, in what format, on what cadence, and whether you can pull them yourself. A monthly slide deck is not a data contract. A file or feed you can join to your order records is. Write a review rhythm and a remediation ladder. A missed target in one period triggers a written root cause. Repeated misses trigger a corrective action plan with a named owner and a date. Persistent misses trigger whatever commercial remedy you negotiated. Remedies do not need to be large to work; they need to be automatic, because a remedy that requires you to argue for it will never be claimed. Finally, connect the reporting back to decisions you actually make. Returns data is worth collecting only if it changes something: a listing that gets rewritten, a variant that gets paused, a supplier check that gets added, a product that leaves the catalog. Ask for the reason code breakdown at variant level, because that is the level at which those decisions are made, and a catalog-level report will never tell you which size or color is generating the complaints.

Vague Clause Versus Enforceable Clause

How BringGo Ship Writes the Returns Side of an Account

We give sellers a return address in Mexico and receive those parcels at our Monterrey warehouse, with our Laredo facility handling the flow that moves from the United States into the country. When a return lands, we scan it, record the timestamp, inspect it against the grading rules the seller gives us, photograph what the seller asked to see, and write both the buyer-declared reason and the condition our team actually observed. Sellable units go back into available stock. Units that need repackaging, repair or a decision go to a named hold location, and we send the seller the record rather than guessing on their behalf. We agree the grades, the exception categories and the reporting fields with each account before the first parcel arrives, and we publish the timestamps behind our numbers so a seller can check our reporting against their own order data. We answer in English, Spanish and Turkish. Where a return raises a regulatory or product compliance question, we tell the seller what we are seeing and hold the unit while they get it confirmed with a qualified specialist.

Definitions

• Returns SLA: A written agreement that ties each step of the returns process to a start event, a finish condition, an owner and a consequence.
• Disposition: The decision about what happens to a returned unit after inspection: back to sellable stock, repack, repair, liquidate or dispose.
• Cycle time: The elapsed time between two defined events in the returns path, reported per leg rather than as one blended figure.
• Carve-out: A named category of returns that leaves the standard process and is measured on its own route instead of breaching the main clock.

Frequently asked questions

Should the returns SLA cover the time the buyer takes to ship the item back?

Track it, but do not put it in the warehouse clause. Buyer delay is real and it affects your customer experience, so it belongs in your internal reporting as its own leg. Holding a warehouse to a period it does not control makes the whole agreement unenforceable.

What is the single most important clause to get right?

The disposition defaults. Without a default action for each grade, every return becomes an individual decision, and the decision cost quickly exceeds the value of the unit. Defaults also keep sellable inventory moving back to available stock without waiting on an email.

How many grades should a grading scheme have?

Few enough that an operator can apply them without calling you. Four states covering sellable as new, sellable after repack, needs repair, and not sellable works for most catalogs. Add a grade only when it triggers a genuinely different action.

Does a returns SLA protect my Amazon Mexico account health?

Indirectly. The marketplace measures your account, not your vendor, so the SLA does not transfer the risk. What it does is give you a faster, evidenced returns path and exportable timestamps, which is what you need when you have to explain a case with data instead of assertions.

What should happen to units that are not sellable and not worth repairing?

Write an aging rule. Give the unit a defined holding period in a quarantine location, then a named default action once that period ends. Without it, unsellable stock quietly occupies space you are paying for and never gets a decision.
