Why You Should Move Complexity Into NetSuite
(Not Your Middleware)
You know the story. You’ve got your Shopify orders flowing through to your ERP, your warehouse integration’s humming, and everything should be running like clockwork. But then the returns logic breaks again. Or you need to update a shipping rule. Or your middleware partner says, "That'll take two sprints."
This is the trap: pushing too much logic into your middleware. It feels faster in the short term. It seems like the best place to handle refunds, order validation, or even the odd stock split. But when it’s time to scale or iterate, you’re left tangled in a web of brittle scripts and unmaintainable flows.
Let’s talk about why moving complexity into NetSuite can save you time, money, and a few headaches along the way.
Middleware isn’t your operations brain
Middleware is great at moving data. That’s its job. But when you start asking it to behave like a decision engine, to process conditional refunds, parse fulfilment statuses, or determine whether an item gets a credit memo or a customer refund, you’re pushing it beyond its pay grade.
Why’s that a problem?
You end up replicating business logic in a black box that ops can’t touch
Change requests (even small ones) go into dev queues
Every new scenario adds to the sprawl, until your flow diagrams look like spaghetti
Instead of building another clever workaround in your middleware, you could build a restlet in NetSuite that handles it natively, with the right records, validations, and visibility.
You’re already paying for NetSuite, use it properly
If your brand’s running NetSuite, you’ve already invested in one of the most powerful operational tools in retail. But many businesses barely scratch the surface of what it can do.
We’ve seen too many brands treat NetSuite like a passive database, just a place to store orders and stock. But it can (and should) be the active system that:
Determines refund flows based on fulfilment status
Sends real-time inventory deltas to your storefront
Splits stock by geo demand
Handles over-receipts and reconciliations
You just need to move the logic where it belongs.
The case for restlets
We’ve implemented restlets for brands to manage the complex stuff like refunds, inbound shipments, order processing, even efficient data extraction.
What do you get?
Better performance (fewer API calls, less load on middleware)
Easier cross-team collaboration (NetSuite SI handles NetSuite, your integrator handles the pipes)
More control and visibility (especially for finance and ops)
With refunds, for example, NetSuite offers different record types depending on whether the item was shipped or not. Trying to recreate that branching logic in middleware is a nightmare. But in NetSuite, it’s native.
6 restlets you should implement today
Here are the restlets we recommend most for commerce brands using NetSuite:
1. Order Creation Restlet
Push new orders into NetSuite using custom logic that prioritises speed and flexibility. Especially useful during peak trading periods, like Black Friday, where ops teams need to get orders out the door fast, and financial clean-up can follow afterward.
2. Refund Handling Restlet
NetSuite has multiple refund record types (credit memo, customer refund, cash refund) depending on fulfilment status. This restlet ensures the right type is created every time, without middleware hacks or manual intervention.
3. Inventory Extraction Restlet
Generate clean, structured inventory data by combining multiple saved searches into one API call. This dramatically reduces the number of calls required to keep your WMS or marketplace channels in sync.
4. Inbound Shipment Over-Receipt Restlet
Allows your DC to receive more stock than expected without breaking the workflow. NetSuite’s native functionality doesn’t allow this, so this restlet smooths over the operational reality of receiving.
5. Inventory Event Publisher
Technically not a restlet, but a custom script worth mentioning. It fires real-time inventory adjustments out to Shopify (or any front-end platform) the moment something changes in NetSuite, no more daily/hourly batch syncs.
6. Dynamic Stock Split Restlet
Custom restlet that analyses geographic order data and automatically allocates stock across your DCs based on demand. Ideal for multi-region retailers balancing stock levels in real time.
Implementing even a few of these can transform how NetSuite serves your business, not just as an ERP, but as an active engine for your operations.
It’s not just technical, it’s strategic
Moving complexity into NetSuite isn’t about chasing purity. It’s about creating a setup that’s resilient, scalable, and easier to change when things shift (because they always do).
If your operations team has to wait a week for a new shipping rule, or worse, they don’t even know how the logic works, you’ve got a problem. But if that logic lives in NetSuite, where it belongs, changes can be made faster, tested in sandbox, and deployed cleanly via bundles.
Middleware should be the messenger. NetSuite should be the brain.
TL;DR
If you’re:
Constantly fixing refund logic
Dreading every promo because the ops flows might break
Dependent on a dev team for every operational tweak
Then it’s time to re-evaluate where your complexity lives.
