Frequently asked questions

$35 per month, per company, billed monthly. One subscription covers unlimited warehouses, unlimited products, and unlimited transactions on the connected QuickBooks Online company.

You give us a card at sign-up so we can verify you're a qualified business — but we don't bill it until day 31. Cancel any time during the first 30 days for $0. After day 30, your card is automatically charged $35 and rebilled monthly.

It filters for serious businesses, not browsers. We invest real time provisioning your tenant, importing your QuickBooks Online data, and routing real journal entries to your books. Card-on-file means we know we're working with a real customer who plans to use the product.

Yes — each company you connect is its own subscription at $35/month. Useful for accounting firms or holding companies with multiple QuickBooks Online files. Each company's data is isolated in its own database; the same login can switch between them.

At setup we pull your chart of accounts, items, vendors, and customers so we can map them to FLC's internal SKU and warehouse model. After go-live we pull bills (for cost layers) and credit memos (for returns).

For any sales entered directly in QuickBooks Online (sales receipts or invoices that don't come from an Amazon / Shopify / Walmart connector) we also pull the line items — we read the units per SKU so cost layers consume correctly. Dollar amounts are ignored on our side; revenue is already booked in QuickBooks Online.

For Amazon, Shopify, or Walmart sellers, sales come into FLC through platform-specific inventory CSVs (FBA Shipped Items, Shopify Inventory, Walmart Inventory) — we don't pull those again from QuickBooks Online to avoid double-counting. Sales revenue stays in QuickBooks Online via your A2X / Synder / native connector.

FLC writes Journal Entries and Inventory Adjustments via the official QuickBooks Online OAuth 2.0 API:

• COGS journal entries from FIFO consumption when sales come in
• Inventory Adjustments for shrinkage, write-offs, and starting balances
• Reconciliation journal entries when month-end variances need to land in the GL

Nothing posts behind your back — every entry is staged on the /review-sync page for line-by-line review before it touches your books.

Intentional. The FLC pattern is: FLC Multiple Warehouse owns stock counts and FIFO costing; QuickBooks Online owns the GL. If your items were Inventory-type in QuickBooks Online, QuickBooks Online would auto-generate its own COGS journal entries that would compete with ours. NonInventory items skip that, which keeps your books clean and the two systems in agreement.

Yes — there's a Disconnect button in the sidebar of every page, plus on /setup. Clicking it calls Intuit's official Revoke Access API to invalidate the OAuth token, then deletes the encrypted credentials from our database. Your QuickBooks Online data is unchanged; only the connection between FLC and your books is severed.

Never. We use Intuit's OAuth 2.0 + OpenID Connect flow, so authentication happens on Intuit's side and we only ever see the access and refresh tokens they hand us. Tokens are encrypted at rest with Fernet (AES-128 + HMAC-SHA256).

Direct upload via CSV: Amazon (FBA Shipped Items + FBA Inventory + Ledger), Shopify (orders + inventory exports), and Walmart (orders + inventory). For any sales entered directly in QuickBooks Online — sales receipts, invoices, manual sales — we also pull the line items and consume cost layers off the units. Other channels work as long as you can produce a CSV with SKU + quantity columns; the dollar amount column is optional and only used for variance reporting (revenue stays in QuickBooks Online either way).

That's literally the whole point of the product. You can have unlimited warehouses (Main, FBA, Returns, East Coast DC, etc.), each with its own on-hand counts and cost layers. Transfers between warehouses move both the units and the FIFO cost layers attached to them.

Every purchase creates a "cost layer" — a record of (warehouse, SKU, qty, unit cost, receipt date). When a sale ships, we consume the oldest cost layer first, generating an exact COGS amount that traces back to the specific purchase batch. Layer-2 overhead (freight, customs, storage) absorbs into cost layers via configurable allocation rules so your landed cost reflects what units actually cost to land.

A return restocks the units with a fresh cost layer (since you can't always tell which original batch they came from). You can also issue a credit memo in QuickBooks Online and FLC will pull it during the next sync; the COGS impact reverses automatically.

Each customer gets their own PostgreSQL database hosted in AWS us-east-1, isolated from every other tenant. QuickBooks Online tokens are encrypted at rest. We never touch other tenants' data.

Your QuickBooks Online books continue working with no change — every transaction we ever posted is sitting in your QuickBooks Online ledger. We also email a monthly transaction statement so you have an external record. Disconnecting from FLC is a one-click operation that revokes our access and leaves your books intact.

Yes — the "Delete My Account" button on /setup revokes the QuickBooks Online connection, soft-deletes your company, deactivates user mappings, and deletes the user record from our identity provider. The QuickBooks Online entries we previously posted to your books stay where they are (your books, your data); only the FLC-side records are removed.

Yes — FLC Multiple Warehouse is an Intuit App Partner — Silver tier. The integration is built strictly to Intuit's security and branding guidelines, uses the official OAuth 2.0 + OpenID Connect flow, and revokes tokens immediately on disconnect via Intuit's Revoke Access API.

The Help page has a 9-step closing checklist. Short version: get physical warehouse counts, foot to the local ledger, confirm transactions are in, reconcile to QuickBooks Online, calculate COGS, allocate overhead, review & post pending journal entries, generate reports, lock the period.

No. The Help page has step-by-step checklists for daily operations and month-end close, and every screen explains what it's about to do before it does it. If you can use QuickBooks Online, you can use FLC Multiple Warehouse.

Inventory-based businesses with two or more locations: e-commerce sellers using Amazon FBA + their own warehouse, multi-state retailers, manufacturers with raw-materials and finished-goods warehouses, anyone running a hybrid 3PL + own-warehouse model.
