Nautilus plugs into the stack you already run

Your accounting, storefront, and shipping tools already work. Nautilus is built to sit next to them and keep the floor and the books in sync — not to replace them.

We don't think a warehouse system should demand that you rip out everything else. Your books live in your accounting tool, your storefront is wherever you sell, your shipping runs through a carrier platform. Nautilus is designed to connect to those, not push them out.

Accounting and ERP

Connections to tools like QuickBooks, Xero, FreshBooks, Sage, NetSuite, and SAP Business One mean inventory movements on the floor flow into your books. Receipts, cost of goods, and inventory valuations stay current without anyone keying journal entries by hand.

E-commerce and POS

With your sales channels connected — Shopify, WooCommerce, Amazon, Square, BigCommerce, Lightspeed — a sale decrements warehouse stock, so you're not overselling the same unit across two channels, and fulfillment can begin the moment an order lands.

Shipping and logistics

Shipping connections — ShipStation, Shippo, EasyPost, and carriers like FedEx, UPS, and DHL — let a picked order move into your shipping platform, print a label, push tracking back to the sales channel, and notify the customer, off the back of the same workflow your team already runs.

We'd rather a smaller set of connections that go deep than a long list of shallow ones nobody uses twice. The Integrations page in the dashboard has the current list and what each one syncs.
