Question 1

What is Flywheel by Sellistix?

Accepted Answer

Flywheel is marketplace settlement reconciliation software for Amazon US and Walmart US sellers. It helps you go from payout to every fee line, to the order, to the raw settlement report, and tie returns back to the original order. Flywheel also tracks operational COGS at your unit costs on an always-on inventory ledger. It is operated by Sellistix LLC and is currently in an invite-only beta.

Question 2

How does Amazon and Walmart settlement reconciliation work in Flywheel?

Accepted Answer

Flywheel syncs settlement reports from your connected marketplaces on a schedule. Each settlement period shows its payout amount, deposit date, and a tie-out badge that compares the payout to the sum of fee lines (accurate to ±$0.01). Filter, sort, and export the lines, or open an order to read its chronological fee timeline and download the underlying report. The same workflow applies to Amazon US and Walmart US.

Question 3

Which marketplaces does Flywheel support?

Accepted Answer

Flywheel supports Amazon US and Walmart US seller accounts only. Other Amazon marketplaces, international Walmart stores, eBay, Shopify, and other channels are not in scope at launch. All pricing and order counts are in USD.

Question 4

How do I connect Walmart?

Accepted Answer

Amazon US connects with Seller Central sign-in in the app. Walmart US uses assisted connect during beta. Partner / App Store sign-in is not self-serve yet. Open a support ticket from Marketplace (or email support@sellistix.com) so Sellistix can bind your Walmart seller account. Do not paste API keys into Marketplace. Once connected, Walmart gets the same reconciliation depth as Amazon.

Question 5

Is Flywheel accounting software or a full P&L?

Accepted Answer

No. Flywheel is not accounting software, bookkeeping, or tax reporting. It computes operational COGS from unit costs you provide and settled marketplace orders, not a full P&L. Marketplace fees, shipping you pay, operating expenses, and sales outside connected marketplaces are excluded. See  in our glossary for the full definition.

Question 6

How much does Flywheel cost?

Accepted Answer

Flywheel uses honest, order-based monthly pricing. No per-seat fees. Plans: $39/mo (up to 200 orders / month); $59/mo (up to 750 orders / month); $99/mo (up to 1,500 orders / month); $179/mo (up to 3,000 orders / month). Every plan includes the same features. 14-day free trial on signup; no credit card required to create your account. If your order count exceeds your current tier limit during a billing period, your plan auto-upgrades to the next tier (prorated). Downgrades take effect next period when eligible. See .

Question 7

How are returns tied back to the original order?

Accepted Answer

When a return arrives, even before the settlement that contains the refund fee, Flywheel links it to the originating order. Returns in transit appear in an in-flight queue with a needs-attention flag if they stall. When the settlement lands, Flywheel matches the return to the refund fee so you can see the full story on one order timeline.

Question 8

What is a payout tie-out badge?

Accepted Answer

Each settlement period in Flywheel carries a tie-out badge (Balanced or Mismatch) that compares the marketplace payout to the sum of its transaction lines, accurate to ±$0.01. A Balanced badge means the numbers tie; Mismatch means something needs your attention before you trust the period.

Question 9

What is operational COGS?

Accepted Answer

Operational COGS is the cost of goods sold Flywheel allocates on settled marketplace orders using unit costs you provide. It runs on an always-on inventory ledger that tracks on-hand quantity and movements. It excludes marketplace fees, shipping you pay, operating expenses, and sales outside connected marketplaces. Operational COGS, not a full P&L.

Question 10

If I change a unit cost, does Flywheel update COGS on old orders?

Accepted Answer

Not by default. Flywheel uses a prospective-only cost policy: confirmed COGS on past orders keeps the unit cost recorded at allocation. New sales and lines without COGS yet use your updated cost. Before saving a cost change, Flywheel shows a confirm dialog with impact counts. Account owners can deliberately correct historical COGS with the Restate COGS workflow (separate from an ordinary cost edit).

Question 11

Can I correct COGS that was already allocated on past orders?

Accepted Answer

Yes. Account owners with Account Edit permission can run Restate COGS in the app: scope affected SKUs or order lines, preview the delta, record a reason, and execute an auditable restate job. Job history lives on Inventory → Restate COGS → History. That is your correction audit trail; ordinary cost edits stay prospective only.

Question 12

How long does initial sync take after I connect?

Accepted Answer

Timing depends on your order volume and how much settlement history each marketplace exposes. Many sellers see their first settlement periods within 24 to 48 hours after a marketplace is connected (Amazon self-serve, or Walmart after assisted bind). Deeper historical backfill continues on a schedule. We will refine this guidance as more beta sellers onboard.

Question 13

Can I use Flywheel for multiple client accounts?

Accepted Answer

Yes. 3PLs, prep agencies, and firms supporting marketplace sellers can accept invitations to multiple client seller accounts under one operator login. Switch between accounts from the header. Each account's data stays separate. See .

Question 14

What data does Flywheel retain if I cancel?

Accepted Answer

At a high level, your marketplace connection credentials are revoked and active sync stops when you cancel. Retention of historical settlement and order data is governed by our  and your account settings. Contact support@sellistix.com before canceling if you need an export.

Question 15

How does Flywheel protect my marketplace credentials?

Accepted Answer

Marketplace credentials are encrypted at rest and used only to pull your seller data on your behalf. Flywheel runs with per-tenant data isolation, defined retention policies, and a published sub-processor list. Read  for the full picture.

Question 16

Does Flywheel include inventory and purchase orders?

Accepted Answer

Yes. Flywheel includes an always-on inventory ledger (on-hand quantity, movements, locations, suppliers, purchase orders, and replenishment flows) with operational COGS allocated on settled orders at your unit costs. Costing methods include cost-only, weighted average, and FIFO. Marketplace on-hand sync covers Amazon FBA/MFN and Walmart WFS/seller-fulfilled into those locations.

Question 17

Can Flywheel print FBA labels from my own printers?

Accepted Answer

Yes for Amazon US FBA inbound. Set up a small-label printer for FNSKU stickers and warehouse box ids, plus a 4×6 printer for Amazon shipping labels, under Settings → Printing. You can still download letter PDFs for an office printer. See  for the broader FBA prep and ship path.

Question 18

What happens after my free trial ends?

Accepted Answer

14-day free trial on signup. No forever-free plan. No credit card required to create your account; add a payment method in the app before your trial ends to continue service. If you add a payment method before the trial ends, billing follows your monthly order volume on the tier that matches your usage.
