How to reconcile amazon seller settlements as CPG Founders
Every two weeks Amazon deposits a number in your bank account, and it rarely matches what you expected. You pull the settlement report from Seller Central — a flat file with 40+ columns — and try to reconcile it against your COGS in QuickBooks, your FBA fee estimates in a spreadsheet, and your ad spend in Amazon Ads. Somewhere in the gap are reimbursements Amazon owes you for lost or damaged inventory, shortfalls from Reserve holds, and chargebacks you never disputed. Most CPG founders spend 3-5 hours per settlement period on this and still aren't confident the number is right. If you're running multiple ASINs across grocery and DTC, it gets worse fast.
What you'll set up
Apps, data, and prompts
The combination of Starch apps, the data sources they pull from, and the prompts you use to drive them.
Starch connects directly to Amazon Seller Central via the Amazon Seller Dashboard app (currently in beta — request access) for settlement report data and FBA fee detail. Starch syncs your Plaid bank account data on a schedule to match cash deposits against expected settlement amounts. Starch syncs your QuickBooks data on a schedule — pulling invoices, payments, and journal entries — to reconcile revenue recognition against actual disbursements. Amazon Ads spend data is pulled live from Starch's integration catalog when your reconciliation app runs.

March 2026 Settlement Reconciliation — Grain-Free Granola Brand, 6 ASINs
| Amazon gross sales (3 settlement periods) | 84,200 |
| FBA fulfillment fees | -18,900 |
| Referral fees (8% grocery category) | -6,736 |
| Storage fees (Q1 long-term storage spike) | -3,100 |
| Amazon Ads spend (auto + branded campaigns) | -11,400 |
| Reserve hold (new ASIN launched Feb) | -4,200 |
| Reimbursements — lost FBA units (flagged by Starch) | 1,840 |
| Net cash deposited (Plaid verified) | 41,704 |
In March, this brand ran $84,200 in gross Amazon sales across six granola SKUs. Their QuickBooks showed $79,000 in revenue recognized — a $5,200 gap the founder assumed was timing. Starch's reconciliation showed it was a combination of a $4,200 reserve hold on a new ASIN launched in February (normal, releases in 90 days) and $1,000 in settlement adjustments from a January return dispute Amazon resolved late. More importantly, Starch flagged $1,840 in reimbursements for 47 units Amazon confirmed as lost in transit during a peak restock in February — units the brand had shipped and never received credit for. The founder had no idea. After subtracting all fees and ad spend, net margin on these six SKUs came in at 49.5% of gross — down from 54% in Q4. The culprit: long-term storage fees tripled because a slower-moving SKU had been sitting in FBA since October. Starch identified the SKU, calculated the storage cost per unit, and suggested a removal order. Total time to run the reconciliation: 20 minutes, versus the 4+ hours the founder previously spent manually parsing settlement flat files in Excel.
