From custom scripts to full integrations — everything you need to make NetSuite fit your business, not the other way around.
Custom scripts that add the logic NetSuite can't do out of the box. Validations, automation, calculations, and business rules — written right.
Connect NetSuite to Shopify, Amazon, 3PL providers, CRMs, payment gateways, or any system with an API. Real-time sync, not CSV uploads.
Automate approval chains, status changes, email alerts, and multi-step processes. Stop chasing people by email — let NetSuite do the routing.
Build saved searches, KPI scorecards, and custom reports that give your team visibility without exporting to spreadsheets.
Branded invoices, purchase orders, packing slips, and custom transaction forms that look professional and meet your industry's requirements.
Fractional NetSuite developer on retainer. Troubleshooting, enhancements, release prep, and someone who already knows your account when something breaks.
Clear scope, fast delivery, no surprises. Every project follows the same proven process.
I review your current NetSuite setup, understand the business problem, and define exactly what needs to be built — before writing a single line of code.
Development in a sandbox account with full testing. You see progress incrementally — no black-box handoffs at the end.
Controlled deployment to production with verification steps. If anything doesn't work as expected, I fix it immediately.
Post-launch support included. Need changes? I already know your system. Enhancements are fast because there's no ramp-up.
Business value, not just code. Here is what NetSuite development looks like when it solves actual problems.
Real-time pricing sync across NetSuite SuiteCommerce & Google Shopping
Dynamic promotional pricing in NetSuite never matched the Google Shopping feed, causing constant policy violations and thousands in lost monthly revenue.
SuiteScript middleware automates NetSuite-to-HubSpot inventory sync
HubSpot CRM showed wrong pricing for hundreds of products. The integration was matching on a blank field, failing to sync inventory — sales operated with outdated data.
If any of these sound familiar, we should talk.
Out-of-the-box NetSuite covers maybe 70% of your process. You need custom scripts, fields, and logic for the rest.
Manual data entry between NetSuite and Shopify, a CRM, or a 3PL. It's slow, error-prone, and someone's full-time job.
PDFs in inboxes, no audit trail, bottlenecks everywhere. Approvals that should take hours take days.
Someone set up NetSuite wrong. Bad scripts, broken workflows, wrong custom fields. You need someone to clean it up.
You need NetSuite work regularly but not 40 hours a week. A freelance developer on retainer or hourly is the right fit.
Your team exports data to Excel because NetSuite's default reports don't show what you need. Time to build it properly.
I start with your business problem, not a tech stack. The code is just the tool — the outcome is what matters.
You talk to me. I write the code, I test it, I deploy it. No handoffs, no lost context, no "let me check with the team."
Hourly, project-based, or retainer — whatever fits. No minimums, no long-term contracts unless you want them.
Based in Rio de Janeiro, working with clients across the US, UK, and Europe. Native English speaker, overlapping business hours.
Best for ad-hoc fixes, debugging, and small enhancements. Pay only for what you use.
Fixed scope, fixed price. Ideal for integrations, new scripts, or workflow builds where the requirements are clear.
Dedicated hours each month for ongoing work. Priority response, no ramp-up time, and I already know your system.
Tell me what's not working. I'll tell you how I'd fix it. No obligation, no sales pitch — just a straightforward conversation about your NetSuite setup.
Everything you need to know about our NetSuite Development services
SuiteScript is NetSuite's JavaScript-based scripting platform that enables developers to customize, extend, and automate the ERP beyond its out-of-the-box capabilities. A skilled NetSuite developer can build client scripts (real-time field validation and UI changes), user event scripts (automated logic triggered by record actions), scheduled and Map/Reduce scripts (bulk data processing), RESTlets and Suitelets (custom API endpoints and pages), and workflow action scripts. Extra Large Marketing has 12+ years of SuiteScript experience across 50+ projects — we write scripts that handle everything from complex pricing calculations and multi-level approval routing to real-time inventory sync and custom financial validations. If NetSuite doesn't do what you need out of the box, SuiteScript is the answer.
NetSuite development with Extra Large Marketing is available through three flexible pricing models: hourly for ad-hoc fixes, debugging, and small enhancements; project-based with fixed scope and fixed price for integrations, custom scripts, or workflow builds; and monthly retainer for ongoing development with priority response and no ramp-up time. Unlike large NetSuite consultancies that charge $175-300/hour with account managers and junior developers, you work directly with a senior developer who has 12+ years of experience — no handoffs, no lost context, no minimums. For businesses that need regular NetSuite work but can't justify a full-time developer ($80-150K/year plus benefits), a freelance retainer arrangement delivers the same expertise at a fraction of the cost with the flexibility to scale hours up or down.
Yes, we specialize in NetSuite e-commerce integrations, connecting your ERP to Shopify, Amazon, WooCommerce, Magento, and custom storefronts via REST and SOAP APIs. Our integrations deliver real-time, two-way data sync — not periodic CSV uploads. For a recent e-commerce client, we built a custom API data bridge that syncs pricing from NetSuite SuiteCommerce to Google Shopping every 10 minutes, achieving 100% Merchant Center compliance and eliminating price mismatch policy violations. Typical integration scope includes order-to-fulfillment flow (orders flow into NetSuite automatically), inventory sync (stock levels update across all channels in real time), pricing updates (promotional pricing propagates instantly), and customer data unification (single view of customer across all sales channels). Each integration is custom-built to handle your specific business rules, not a one-size-fits-all connector.
We begin with a comprehensive audit of your current NetSuite setup — reviewing all custom scripts, workflows, fields, forms, integrations, and user permissions — to identify exactly what's broken, what's misconfigured, and what's missing. Common issues we resolve include: scripts with logic errors that corrupt data, workflows that create approval bottlenecks instead of reducing them, integrations that match on wrong fields or fail silently, custom fields that were created redundantly or incorrectly, and forms and reports that don't reflect actual business processes. After the audit, we produce a prioritized remediation plan with fixed pricing for each fix. You choose what to address first. We rebuild or replace broken components in a sandbox, test thoroughly, then deploy to production with rollback plans. Our 100% client retention rate means every client who's hired us for cleanup work has stayed with us for ongoing development.
We build NetSuite workflows that automate multi-level approval chains, status changes, email notifications, auto-escalation with reminders, and conditional routing based on department, transaction amount, or custom criteria. Instead of chasing approvals by email with PDFs in inboxes and no audit trail, your team gets automated routing with full visibility into who approved what and when. Common implementations include: purchase order approvals that escalate if not actioned within 24 hours, expense report routing that splits by department and amount threshold, sales order approvals with discount authority checks, and vendor bill workflows that automatically match to POs and route exceptions for manual review. Every workflow includes a complete audit trail for compliance. We can also integrate NetSuite's native workflow engine with external systems via n8n — for example, triggering a Slack notification when an approval is pending or updating a project management tool when a transaction status changes.
Yes, I work with clients across the US, UK, and Europe from my base in Rio de Janeiro, Brazil — 12+ years of experience serving clients on 3 continents. As a native English speaker, communication is seamless, and I maintain overlapping business hours with EST, CST, PST, and GMT time zones. Unlike large consultancies where you're handed between account managers, project managers, and junior developers, you communicate directly with me — the person writing your code. For urgent issues, I provide priority response to retainer clients regardless of time zone. Remote delivery is standard: everything from scoping calls to deployment is handled virtually, with screen sharing for walkthroughs and comprehensive documentation so your team has everything they need.
Each NetSuite release (twice yearly) can introduce changes that affect custom scripts, workflows, and integrations. As part of my ongoing support services, I perform proactive release compatibility checks — reviewing your customizations against release notes before the update hits your account, testing critical scripts in a sandbox environment, and applying any necessary fixes before they become production issues. For retainer clients, this is included as part of regular maintenance. For project clients, I provide documentation of all customizations with notes on potential release sensitivities so your team (or I, if you bring me back) can quickly identify what needs attention. After 12+ years across 50+ projects, I've developed a deep understanding of which NetSuite API changes affect which types of scripts — and a library of patterns that survive releases gracefully.
