BNPL Payment Breakdown
Target + Big Lots runs. 4 installments per order. All paid on time.

July vs June
| Metric | Change |
|---|---|
| Inventory purchased | +$87.40 |
| Net profit | −$31.22 vs June |
| Items sold | +8 vs June |
| ROI on inventory | −4.1% vs June |
| Sourcing runs | Same (5 runs) |
ROI dropped this month despite higher volume — two price-spike buys on the July 8 Target run compressed margins. Both items sold but at near break-even. The Keepa check that was rushed cost roughly $35 in forgone profit.
What Worked
- Klarna Pay in 30 at Walmart on July 1 run — all items sold by July 21, Klarna paid from proceeds before Day 30.
- Back-to-school clearance hit at Target on July 28 — BSR under 80K on all 5 items, expect fast sell-through in August.
- Baby category continues to outperform — all 3 baby items across two Walmart runs sold within 10 days.
What Didn't Work
- July 14 Big Lots run underperformed — 2 of 5 items still unsold at month end. Home décor BSR was 340K; should have passed.
- Net profit down vs June despite more items sold — margin compressed on July 8 Target run. Checked Keepa too quickly on 2 toys that turned out to be price spikes. Bought and sold at break-even.
- SellerAmp subscription ($19.99) is the right call. Skipped it for 3 days in July during trial expiration gap — those 3 days produced zero profitable buys without Keepa chart access.
August Outlook
Three factors that will shape August:
-
Back-to-school clearance startsThe July 28 Target back-to-school buy should sell through fast in early August as remaining school supplies clear. Expect that $198 run to produce strong ROI.
-
Walmart toy clearance cycle beginsLate July/early August is when Walmart marks down remaining summer toys to make room for fall. Planning two Walmart runs in the first two weeks of August.
-
6 pending items from Big LotsThe underperforming home décor from July 14 needs to sell or get a price adjustment. If BSR doesn't improve by August 15, pricing down to move inventory before Q4 storage fee surge.

Frequently Asked Questions
Yes. Every number in these reports is pulled directly from Amazon Seller Central payout statements and BNPL app payment histories. We document what actually happened — including bad buys, slow weeks, and missed payment timing — not a curated highlight reel. See our Earnings Disclaimer for full context on why your results may differ.
Net profit = Amazon gross payouts − Amazon fees (already deducted from payout) − inventory cost (BNPL-funded) − shipping to FBA − tool subscriptions (SellerAmp, Keepa). We do not subtract BNPL interest because all BNPL used is 0% interest. We do subtract any late fees paid.
Because most income reports online are curated success stories. Showing real month-to-month data — including slow months, bad buys, and timing problems — is more useful for someone deciding whether to start than seeing only the best-case scenarios. These reports exist to set accurate expectations, not to inspire with inflated numbers.
