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 on Amazon, Faire, and eBay, this kind of marketplace bookkeeping can eat a large part of the week — and that's before accounting for errors. Shopify and Walmart posting is coming soon.
We built Simentri to take that settlement work off your plate.
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 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 to your live selling channels — Amazon, Faire, and eBay — and generates the accounting entries that flow into QuickBooks Online. Shopify and Walmart are coming soon. No manual exports, no spreadsheet gymnastics.
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 after each settlement cycle.
- Generate accounting entries — Transactions are mapped to your chart of accounts and posted to QuickBooks Online.
Every fee, refund, and adjustment is classified and posted — nothing falls through the cracks.
Who Is Simentri Built For?
Simentri is built for product brands doing $250K–$10M in annual marketplace revenue who sell across multiple channels. If you're spending more than an hour a week on marketplace reconciliation, we can give that time back — and give you a clean, accurate set of books every month.
It's particularly well suited for:
- Amazon sellers managing complex settlement reports, FBA fees, and ad cost reconciliation
- Faire wholesale brands reconciling net-60 payouts with per-order commission deductions
- Multi-channel sellers consolidating Amazon, eBay, and Faire into a single QuickBooks Online workflow

Frequently Asked Questions
What marketplaces does Simentri support?
Simentri currently supports Amazon, Faire, and eBay. Shopify and Walmart are coming soon.
Does Simentri work with QuickBooks Online or QuickBooks Desktop?
Simentri integrates with QuickBooks Online. QuickBooks Desktop is not supported.
How long does it take to set up?
Connecting your first marketplace takes under two minutes using OAuth. Most sellers have their first transactions syncing to QuickBooks within 10 minutes of signing up.
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. Simentri posts settlement entries to QuickBooks Online so you are not re-keying every fee, refund, and payout.
