May 2026 was a steady, profit-positive month for Onboard on Amazon, stepping back from April's high. Revenue eased 5.8% month over month to $16,682 and net profit held at $1,168 at a 7.00% margin, down from April's $1,959 as the sales mix softened and the FBA fee load weighed more on lower volume. PPC stayed efficient at a 23.63% blended ACoS and 4.23 ROAS on $1,286 in spend, with TACoS at 7.71%, well below the 12% target. Subscribe and Save held its floor at approximately 322 active subscribers.
The month was defined by loading the scaling pipeline rather than pushing top line. Fresh stock shipped to FBA for a new Orzo Salad variant and an entirely new line, Tuna Pouches, both now staged for a limited-budget marketing test this month. Tuna Cans remained the engine at $9,606 (57.6% of revenue) at a 13.55% margin, and the Salad line continued to catch up at $5,674. The one open inventory gap is the Tuna Fillets Spring Water variant (SKU 500005), out of stock with a replenishment shipment on the way.
Profit held above $1,000 and the launch pipeline was loaded.
Net profit stayed at $1,168 on a 7.0% margin while two new launches, a new Orzo Salad variant and the entirely new Tuna Pouches line, reached FBA and are staged for a limited-budget test. Tuna Cans held as the engine at $9,606 (57.6% of revenue) at a clean 13.55% margin, and PPC stayed efficient at a 23.63% ACoS and 4.23 ROAS. Buy Box held at 98.8% and the Subscribe and Save floor sat at roughly 322 subscribers. The two compliance items that were pending in April have also cleared.
Margin compressed and a hero variant went out of stock.
Net margin fell from 11.06% to 7.0% as revenue eased 5.8% and the sales mix softened against a fixed FBA fee load. The Tuna Fillets Spring Water variant (SKU 500005) is out of stock with paused Subscribe and Save subscribers waiting on it, and the Tuna Fillets parent slipped to a -6.78% margin on the gap. Tuna Bites remained a small loss on tiny volume. This reads as a soft month plus a single stock gap, not a demand problem.
New Tuna Cans flavors, the launch test, and the Fillets restock.
The clearest scaling lever is launching two to three new Tuna Cans flavors: cans are now the largest line and competitors typically run five to six flavors that sell well. The Orzo Salad and Tuna Pouches limited-budget test reads through in June and gates any spend increase. The Spring Water Fillets restock brings back both the listing and its paused S&S subscribers in one step. Salads continue to catch up and are worth sustained efficient support.

Reconciliation note: Child-SKU rows sum to $16,682 in Sales and $1,622 in Net Profit. The Parent-Level KPI table totals $16,682 in Sales and $1,476 in Net Profit, and the account dashboard reports $1,168 net. The differences are SellerBoard parent-level rollup adjustments plus a ~$308 account-level adjustment, none of which allocate down to individual children. Use the child-SKU rows above for per-SKU accounting entry; the account net reconciles when the P&L dashboard is added.

Action with the brand team: Spring Water Fillets restock is on the way per the brand team. About 17 Subscribe and Save subscribers are paused on this variant waiting for the listing to return, so reactivating it brings back both the listing and the paused subscribers in one step. Separately, the new Tuna Pouches and Orzo Salad have landed at FBA and are ready for a limited-budget launch test this month.

Summary: Account is in a clean operating position with a 0% Order Defect Rate on 869 FBA orders over the trailing 60 days. The two items pending in April, the INFORM Consumers Act priority action and the Regulatory Compliance issue, have both cleared this month, so there are no open policy items. Account Health Assurance is enrolled; only a minor emergency-contact verification banner remains. The 248 / 1000 rating holds steady.
This is the clearest lever to scale the account. Tuna Cans is the largest line at $9,606 (57.6% of revenue) and the strongest margin in the catalog (13.55%), and competitors typically run five to six flavors that sell well. Adding two to three popular flavors to the cans line builds on proven demand rather than starting cold on a new format.
▶ Brand Team
Stock for the new Tuna Pouches (Olive Oil and Spring Water) and the Orzo Salad variant has landed at FBA. Start the limited-budget PPC test this month, watch first-weeks conversion, and gate any spend increase behind a clear per-SKU conversion read before scaling.
▶ Brand Team
SKU 500005 is out of stock with a replenishment shipment on the way. Reactivating it returns the listing and the roughly 17 paused Subscribe and Save subscribers in one step, and lifts the Tuna Fillets parent back out of its current negative margin.
▶ Brand Team
The Salad line at $5,674 is catching up, with Italian leading and Mexican and Quinoa profitable. Keep efficient PPC behind the salads and protect their Buy Box. This is the second growth engine behind the cans and worth steady support rather than a spend cut.
▶ PPC Team
PPC ran at a 23.63% blended ACoS and 4.23 ROAS in May, healthy for the catalog. No structural changes needed. The only pacing question is whether to lift spend on the new SKUs once they are fully available and reading well at FBA; pull that trigger only after a conversion read.
