Introducing Simentri: Automated Marketplace Bookkeeping for Amazon, Faire & eBay
Managing the books for a marketplace business used to mean downloading CSVs, matching settlements, and manually mapping every fee, refund, and payout to your chart of accounts. For sellers across Amazon, Faire, eBay, and Shopify, this kind of marketplace bookkeeping can consume 5–10 hours per week — and that's before accounting for errors.
We built Simentri to eliminate that work entirely.
Why Is Marketplace Reconciliation So Hard?
Every marketplace has its own settlement schedule, fee structure, and payout format. Amazon holds reserves and charges referral fees, fulfillment fees, and advertising costs — all in a single settlement report. Faire operates on net 60 terms with a different fee model. eBay calculates managed payments separately from shipping.
When you sell across three or four channels, reconciling each one manually means exporting different report formats, cross-referencing payouts, and manually entering journal entries into QuickBooks. A single missed fee or misclassified refund can distort your P&L for the entire month.
What Does Simentri Do?
Simentri connects directly to your selling channels — Amazon, Faire, eBay, Walmart — and automatically generates the accounting entries that flow into QuickBooks. No manual exports, no spreadsheet gymnastics. Sellers using Simentri recover an average of 6 hours per week previously spent on marketplace reconciliation.
How Does Simentri Work?
- Connect your marketplaces — OAuth-based connections take under two minutes per channel.
- Sync your orders and settlements — Simentri pulls order data, fees, shipping costs, and payout amounts in real time.
- Generate accounting entries — Transactions are mapped to your chart of accounts and pushed to QuickBooks automatically.
Every fee, refund, and adjustment is classified and posted — nothing falls through the cracks.

Is my marketplace data secure?
Yes. Simentri uses read-only OAuth connections to your marketplaces — we never store your login credentials. Data is encrypted in transit and at rest.
How is Simentri different from doing it manually in a spreadsheet?
Manual reconciliation requires downloading settlement reports, interpreting marketplace-specific fee structures, and entering journal entries by hand — typically 5–10 hours per week for multi-channel sellers. Simentri automates every step and posts entries to QuickBooks in real time, eliminating data entry errors and giving you up-to-date financials without the work.
