Open your last Amazon settlement file. There's one number at the bottom, and you almost certainly took it at face value — because the alternative is checking it line by line, and that's a day of work per settlement period you do not have.

That's the leak. It's rarely fraud. It's friction: marketplaces process millions of orders, small discrepancies pile up, and you're the only party with any incentive to catch them. Most sellers never do. The money just quietly stays on the marketplace's side of the ledger.

## What the leak actually looks like

It's not one big error. It's four small ones, repeated across thousands of orders:

1. **Fees charged against the wrong order state** — a referral fee on the pre-discount price, or on an order that was later partially refunded.
2. **Shipping or return fees billed twice** on the exception orders that took a returns-center detour.
3. **Pricing-error reversals applied silently** — the marketplace decides your price was a "mistake," claws back the order economics, and never sends a notice you'd actually open.
4. **Short-shipped returns charged to you** with no proof the unit came back in resalable condition.

Each one is a few dollars. Across a month, it's a real line on your P&L — and it compounds every month you don't look.

## The reconciliation, step by step

Here's the thing: this is *structured* work. Every step is a join against data you already have. That's exactly why it's a good fit for an agent to run while you sleep:

- Pull the settlement file and the order book for the same window.
- Join payout rows to order lines on **order ID**, not on the summary total.
- Apply the marketplace's published fee schedule to each line to get the *expected* payout.
- Diff expected vs. actual. Flag every line short by more than rounding.
- Bucket the shortfalls by pattern, so you can see which leak is biggest.

None of that touches the outside world. It's all reads. oproom does this against your Amazon SP-API and order data overnight and hands you the shortfall in dollars, bucketed, before you've had coffee.

## The dispute is a draft — you still approve it

The only step that changes anything outside is filing the dispute. That's where the agent stops.

oproom drafts the full dispute — order IDs, date range, the fee math, the evidence — and surfaces it as an approval card: here's what we'd file, here's the shortfall, here's the window before it closes. You read it in thirty seconds and tap approve. **Nothing gets filed without that tap.** No autopilot submitting disputes in your name.

Disputes win when they're line-level, evidence-backed, and filed inside the window. The agent prepares all three. You make the call.

## Why this is where most founders start

Of everything an operating agent can do for you, payout recovery is the one I point new founders at first. The leak is real, the math is mechanical, and the money is something you were already owed. It tends to pay for itself before the agent has done anything clever.
