You’ve decided to integrate WooCommerce or Shopify with NetSuite. You’ve ruled out building it in-house — your team doesn’t have the SuiteScript depth, or the runway, or both. Now you’re staring at a list of 30 “NetSuite integration partners,” every one of them claiming senior code, certified consultants, and rapid delivery. Here’s how to pick one without burning $40k learning what doesn’t matter.
There are three kinds of partners. Know which kind you need.
The market lumps everyone under “integration partner,” but the actual work splits into three very different shapes. Hiring the wrong shape is the most expensive mistake you can make.
- NetSuite-first consultants. Big firms, ERP-led, usually came out of NetSuite implementations themselves. They speak SuiteScript fluently, know the ERP side cold, and treat WooCommerce/Shopify as a downstream dependency. Right choice if your NetSuite is heavily customized and the integration has to bend to it.
- Ecommerce-first agencies. Shopify Plus partners, WooExperts, BigCommerce specialists. They know the storefront cold, treat NetSuite as a black box to be tamed, and lean on connector vendors. Right choice if your store is the differentiated piece and NetSuite is mostly stock.
- Integration-first studios. Smaller, technical, focused specifically on the integration layer between systems. They don’t claim to redesign your store or re-architect your ERP — they live in the middle. Right choice when both endpoints are stable and the integration is the project.
If you don’t know which one you need, here’s a shortcut: which side has the most customization? If NetSuite, hire NetSuite-first. If the storefront, hire ecommerce-first. If neither, hire integration-first — they’ll deliver the same outcome at a fraction of the cost.
Ten questions that separate real partners from resellers
Send these in an email. Don’t book a call. If they can’t answer them in writing, they can’t deliver the project.
- How many WooCommerce-to-NetSuite (or Shopify-to-NetSuite) integrations have you shipped in the last 12 months? Look for 5+. Less than 3 is a red flag.
- Can you share a sample data contract from a previous project? A real partner has documented field mappings, sync directions, conflict-resolution rules. If they don’t, they wing it on every project.
- Who writes the SuiteScript — your team or a subcontractor? Subcontracted SuiteScript is a tell. It usually means they lean on connector vendors and don’t touch the ERP themselves.
- What’s your handling of partial refunds and item-level returns? If the answer is anything other than “Credit Memo in NetSuite with line-level mapping,” they haven’t done this in production.
- Is your integration HPOS-native? Mandatory for WooCommerce. If they say “we’ll figure it out,” they will, on your dime.
- How do you handle the first failed sync after go-live? Real answer: idempotent retry queue, dead-letter log, manual reconciliation UI. Vague answers mean “we’ll log in and look at it.”
- What’s your typical setup time, end-to-end? Anything under 2 weeks for a fresh integration is suspicious. Anything over 8 weeks for a standard pattern is overcharging.
- Do you charge a fixed price or T&M? Fixed-price is harder for them, cheaper for you, and forces them to scope properly upfront. Insist on fixed.
- What happens after go-live — do you support, or hand off? Ideally three months of bundled support, then a clear maintenance offer. Walking away at go-live is a deal-breaker.
- Can I talk to two clients you shipped in the last six months? If they hedge, they don’t have happy recent ones.
Red flags that should end the conversation
- “Let’s get on a call to discuss your needs.” Sales process before scope. They’ll spend the call qualifying you, not the project.
- “We can start as soon as you sign.” Either they have no backlog (suspicious for a senior team) or they over-promise.
- “We use [vendor]’s connector under the hood.” Fine if disclosed, deadly if you find out later. You’re paying agency rates for a $300/yr SaaS.
- No fixed-price option. Pure T&M means they don’t know how to scope, or they’re banking on overruns.
- Vague timelines like “8 to 16 weeks.” A team that’s done 20 of these projects knows exactly how long it takes.
- No written deliverables list before kickoff. You’ll spend the entire project arguing about what was included.
What good pricing looks like
Ballparks from the market in 2026. Yours will vary, but if you’re 2× outside any of these, ask why.
| Scope | Typical price (USD) | Typical timeline |
|---|---|---|
| WooCommerce ↔ NetSuite, standard pattern | $2,500 – $5,000 | 10–14 business days |
| Shopify ↔ NetSuite, standard pattern | $3,000 – $6,000 | 10–14 business days |
| Multi-subsidiary, multi-warehouse | $8,000 – $20,000 | 3–6 weeks |
| B2B with custom pricing tiers | $10,000 – $25,000 | 4–8 weeks |
| Custom plugin / SuiteApp build | $15,000 – $60,000 | 6–12 weeks |
What to demand in the contract
- Fixed scope and fixed price for standard work, with a clear change-request process for additions.
- Source code ownership. You own the code. No “licensing back to you” arrangements for bespoke work.
- Acceptance criteria per deliverable. A test plan, not “looks good.”
- Bundled post-go-live support — at minimum 30 days, ideally 90.
- Exit clause. If they vanish, you get the latest source, the documentation, and admin access — in writing.
A note on what we sell
We do this work. We’re the third kind — an integration-first studio. We mention this not to pitch you, but because the framing matters: if you read this guide and decide you actually need a NetSuite-first consultancy or an ecommerce agency, hire one. We’d rather lose a project than win one we’re the wrong fit for.
If after the questions and the red-flag check you still want to talk: our scope-and-price page lists what we do, fixed prices, fixed timelines. No discovery calls. No “let’s hop on a Zoom.” Five fields on the contact form. We reply in 24 hours.
The single most expensive decision in this whole category is the wrong partner. Take an afternoon, send the ten questions, and pick the team whose written answers leave you with the fewest follow-up questions. That’s the one.
