Food deductions sit behind portals with no export button. How 2026 browser-driving agents file chargeback disputes in Retail Link, Vendor Central and KeHE.
Key takeaways
That is the honest starting position for most food manufacturers, and it is fair. Somebody sold the plant a scripted click-robot to pull deduction detail out of the retailer portals. It worked for six weeks. Then the portal added a security step, or moved a tab, and the script sat there failing quietly until a controller noticed nobody had disputed anything in two months. The deduction desk went back to a person and a browser, and everyone agreed the technology was not ready.
What changed in 2026 is not a better script. It is that there is no script. The agent looks at the screen the way a person does — reads what is on the page, clicks, types, waits, downloads, files — so when the portal moves the button, it finds the button. In the food business that matters more than almost anywhere, because the money in this trade sits behind portals nobody will ever build a connection into.
Every food manufacturer selling into retail knows the pattern. The invoice goes out at $41,880. The check comes in at $38,214. Between them sit eight or nine deduction codes: a promotional bill-back the broker set up, a shortage claim, an OTIF charge, a case-pack compliance fee, a spoils allowance, and one line that says "audit adjustment" with no backup at all.
Some are legitimate — you agreed to the promotion, you took the ad. Some are duplicates of a deduction taken two months earlier. Some are shortage claims for cases the driver actually delivered, and your signed bill of lading proves it. Getting the wrong ones back means opening the portal, finding the claim, attaching the delivery proof and the invoice, and filing before the window closes — and every account has a different window and a different idea of acceptable backup.
Walmart's supplier side runs through Retail Link and its accounts-payable dispute screens. Amazon shortage and price claims run through Vendor Central. Kroger, Target's Partners Online, Costco, KeHE's CONNECT portal, UNFI's supplier site — each its own login, its own two-factor step, its own download with the columns in a different order. Orders may flow over SPS Commerce; deduction backup does not. It is a website, and only a person with a password can get at it.
Ask your controller for deductions as a percentage of gross sales, and then ask what percentage of the disputable ones actually got disputed last quarter. That second number is the one that stings.
In a $28 million food company there is no deduction analyst. There is an accounts receivable clerk who also does cash application and customer service and has Thursday mornings blocked out for "chargebacks." She logs into four portals, downloads whatever each gives her, pastes it into a workbook, matches promotional deductions against the broker's authorization forms, pulls signed bills of lading out of the warehouse folder for the shortage claims, and files what she can before lunch.

Then the triage, and it is entirely rational: anything under about $250 gets written off, because twenty minutes hunting for delivery paperwork costs more than the claim. Anything with a filing window shorter than a week gets skipped in a busy month. Anything from the account whose password expired waits for IT. That is not laziness. It is one morning a week being spent sensibly.
Meanwhile the pattern that would actually fix the problem — the same customer taking the same wrong deduction code every month on the same item — never gets found, because nobody is looking across months. They are looking at this month's list.

Three things, and they are the three things that used to break.
First, it reads the page instead of memorizing coordinates. When Walmart reorganizes a supplier screen, or Vendor Central changes what the dispute form asks for, the agent reads what is now on the screen and works with it. It does not need a developer to rewrite anything, because there was no script to rewrite.
Second, it holds the whole month at once — the deduction file, the open invoice list from your ERP, the broker's promotion authorizations and the folder of signed delivery paperwork, all together. That is what lets it say "this $1,140 shortage claim is the same 60 cases you were already deducted for in April, here are both." Your clerk could write that sentence too, given a full day per account instead of one morning for all four.
Third, it works the small claims. The $180 items that were never worth a person's twenty minutes are worth an agent's four. Over a year, on a mid-size food company, the small ones are usually the bigger pile.
The clerk opens her email at 7:30. One message. Fourteen deductions came in overnight across four accounts, $9,340 in total. Nine are supported by a promotion authorization or a real short-ship and are already coded to trade spend with the backup attached. Five are not: two duplicates of April deductions, two shortage claims where the signed bill of lading shows full delivery, and one case-pack fee on an item whose pack was changed at the customer's own written request last fall, that email attached.
She reads the five, agrees with four, and kicks one back because the customer is right — the plant genuinely short-shipped that load during the hot-fill changeover week. She clicks approve. The agent files the four with attachments and sets itself a reminder to check status in fourteen days. Total human time: eleven minutes. The message also carries a line the plant has never had before: that same customer has taken the same unauthorized case-pack fee on the same item nine times since January.

Illustration figures for a food manufacturer doing about $28 million with four portal-based accounts. Substitute your own.
| Deduction lines received per month, all accounts | 115 |
| Average deduction line | $395 |
| Total deducted per month | $45,425 |
| Share genuinely owed (real promotions, real shortages) | 72% |
| Disputable per month | $12,719 |
| Actually disputed today, one morning a week | 40% |
| Recovered today, at a 70% win rate on filed disputes | $3,561 |
| Disputed when every line gets worked | 95% |
| Recovered, same win rate | $8,458 |
| Monthly difference | $4,897 |
| Annual difference | $58,764 |
Two things about that number. A recovered deduction is a dollar with no cost of goods attached, so $58,764 is worth what a quarter million dollars of new sales is worth at a typical food-manufacturing margin. And win rate matters more than volume: if your backup is weak, filing more disputes just annoys the customer. Fix the delivery-paperwork filing first.
Do not let an agent hold your only set of portal credentials, and do not let it file anything without an approval click. Give it its own named user in each portal with the narrowest role the retailer offers, so that when someone asks who filed a dispute, the answer is a specific login with a record of what it did. Retailer portal terms vary on automated access — read them, and ask your buyer's admin contact rather than assuming.
Keep the relationship calls human. Some deductions are not accounting problems, they are a signal that your service level slipped and the buyer is unhappy. An agent that mechanically disputes every OTIF charge during a quarter when you genuinely missed three delivery windows is picking a fight the owner would not have picked. Your sales lead should see the OTIF file before anything is filed on it.
They will notice that you are suddenly disputing everything you are entitled to dispute, because most of their suppliers do not. In practice that reads as a supplier with its house in order. What causes trouble is volume without backup, or the same claim refiled repeatedly after a legitimate denial. Attach the proof, accept the losses you deserve, and the relationship is fine.
That is the practical hurdle, and the answer is boring: set up the agent's named user with a code method your finance team controls, and have the clerk approve the session in the morning rather than letting it authenticate unattended overnight. Some portals will not tolerate anything else. Design the routine around a person opening the door once a day.
Yes, and that is often the sleeper win. The same portals hold your fill-rate and on-time detail, your item-level sales, and the compliance charges you are about to be assessed. Having last week's on-time detail on the production scheduler's screen every Monday morning is a smaller job than deduction disputes and it changes what gets run first.
It changes what you pay them for. A firm taking a share of everything it collects is expensive for routine duplicate-claim work. Keep them for the hard audits and historical claims that need someone across a table from the customer, and stop paying a contingency on the routine volume.
One last thing from us. The deduction desk is not the only place a food plant loses money to a screen nobody has time for. The other one is the phone: brokers checking on a load, a buyer's assistant asking for a certificate of insurance, a co-pack inquiry that comes in at 4:50 on a Friday and never gets called back. CallSphere builds AI voice and chat agents that answer the plant's main line and web chat 24/7, capture who called and what item they were asking about, and book the callback — so the inquiry lands on someone's calendar instead of in a voicemail box.
