The Best NetSuite Integrations and Apps in 2026
Oracle NetSuite runs the financials, inventory, orders, and CRM for a lot of mid-market companies — but the ERP only earns its keep when it’s wired to the storefront, the payment processor, the tax engine, and the shipping carrier feeding it data. NetSuite’s SuiteApp Marketplace lists over 700 certified applications, and integration and iPaaS connectors are the single largest category in that ecosystem, so most of the connections you need already exist as prebuilt apps.
Here are the NetSuite integrations actually worth setting up, grouped by what they do — and then the way to connect NetSuite to anything with an API, even when no native SuiteApp exists.
E-commerce: Shopify, BigCommerce, Amazon, WooCommerce
Sync orders, inventory, customers, and product data between the storefront and the ledger so you’re not rekeying sales.
- Shopify (via Celigo) — the go-to connector for Shopify-to-NetSuite, handling orders, inventory, customers, and product data bidirectionally.
- BigCommerce — bi-directional sync of product listings, inventory levels, customer records, and sales orders between the store and NetSuite.
- Amazon — pull marketplace orders and settlements into NetSuite and push inventory back, typically through Celigo’s managed Integration App.
- WooCommerce and Magento — sync sales, inventory, and order data for teams running open-source or Adobe Commerce storefronts.
CRM and sales: Salesforce, HubSpot
Give sales and finance one view of the customer instead of two disconnected systems.
- Salesforce — sync accounts, opportunities, and orders across the quote-to-cash boundary; connectors come from Celigo, Boomi, and Breadwinner.
- HubSpot — tie marketing and sales activity to NetSuite’s customer and financial records for a unified pipeline-to-revenue view.
Payments: Stripe
- Stripe — NetSuite’s native SuitePayments link covers simple one-time charges initiated from NetSuite orders, but for subscription billing and automated cash reconciliation most teams run a dedicated Stripe-to-NetSuite connector that syncs charges and payouts in real time.
Tax and compliance: Avalara
- Avalara AvaTax — automated sales tax calculation and filing, Built-for-NetSuite certified so it survives Oracle’s twice-yearly release upgrades cleanly.
Expense and spend: Expensify, Ramp
Get employee spend and receipts into NetSuite’s financials without manual entry.
- Expensify — the most popular expense SuiteApp; employees snap receipts, the app extracts the data, managers approve, and expenses post straight to NetSuite.
- Ramp — sync coded card transactions, receipts, and bills into NetSuite with custom fields and dimensions mapped to your chart of accounts.
Shipping and fulfillment: ShipStation
- ShipStation — pull orders from NetSuite, generate shipping labels across multiple carriers, and push tracking numbers back so fulfillment status stays current.
iPaaS: Celigo and Boomi
When you have many systems to wire together, a dedicated integration platform beats point-to-point connectors.
- Celigo integrator.io — a NetSuite-native iPaaS built around prebuilt, business-user-friendly Integration Apps; the fastest path when NetSuite is the hub of your stack.
- Boomi — a broad, enterprise-grade platform for wiring NetSuite into a complex IT estate where it’s one node among many, usually owned by a central integration team.
No-code automation: Zapier and Make
- Zapier and Make — connect NetSuite to thousands of apps with simple triggers (“new sales order → do X”). Fine for straightforward field-mapping, but they’re built for basic automation, not for reasoning over your ERP data.
The AI way to connect NetSuite to anything: Carly
Prebuilt SuiteApps and iPaaS connectors cover the big storefronts, CRMs, and tax engines. But the moment you need NetSuite tied to a tool that isn’t certified — or you want something smarter than “new order → copy field” — you’ve hit the ceiling of native integrations and no-code triggers.
Carly is an AI executive assistant that connects to 200+ tools and, crucially, lets you bring your own API key to connect to anything with a REST API — NetSuite included, via your own NetSuite API credentials. Instead of a fixed catalog, you get an agent that:
- Acts on triggers, 24/7 in the cloud — when an invoice posts, a purchase order needs approval, or inventory drops below a threshold, Carly does the next step without you in the app.
- Reasons over your data — not just “copy this field,” but “read this week’s overdue invoices, flag the accounts over their credit limit, and email each owner a summary.”
- Ties NetSuite to the rest of your stack — a new order or bill becomes one step in a workflow that also touches email (Gmail and Outlook), calendar, CRM, and Slack.
- Builds the workflow from a plain-English description — tell it “when a customer’s balance goes past due in NetSuite, message the account manager in Slack and log a follow-up task” and it interviews you, then builds it.
AI agents start at $35/month, and steps in a workflow that don’t use AI run free. See the Claude + NetSuite integration guide for how the API-key connection works.
How to connect NetSuite to a tool with no native integration
- In NetSuite, enable SuiteTalk REST web services and create an integration record, then generate credentials — token-based authentication (TBA) or, for new integrations, OAuth 2.0, which Oracle now recommends over TBA.
- Paste those NetSuite API credentials into Carly on the integrations page.
- Describe the workflow in plain English, and Carly builds it — connecting NetSuite to whatever else you need, on triggers, without your laptop open.
Frequently Asked Questions
Does NetSuite have integrations?
Yes. NetSuite’s SuiteApp Marketplace lists over 700 certified applications across e-commerce (Shopify, BigCommerce, Amazon), CRM (Salesforce, HubSpot), payments (Stripe), tax (Avalara), expense (Expensify, Ramp), and shipping (ShipStation), plus iPaaS platforms like Celigo and Boomi and a SuiteTalk REST API for custom connections.
What is the best NetSuite integration for automation?
For simple triggers, Zapier or Make covers most apps. For automation that acts on triggers and reasons over your ERP data — and to connect NetSuite to tools with no certified SuiteApp — an AI agent like Carly connects via your NetSuite API credentials and runs workflows in the cloud.
How do I connect NetSuite to an app that isn’t listed?
Use NetSuite’s SuiteTalk REST web services. Enable REST web services, create an integration record, and generate TBA or OAuth 2.0 credentials, then hand them to a platform that supports bring-your-own-API-key connections — Carly does this and can wire NetSuite to any tool with an API.
How much does an AI automation for NetSuite cost?
Carly’s AI agents start at $35/month, with non-AI workflow steps running free. Your NetSuite license is separate.

See what people say
"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
