A NetSuite alternative that your company owns.
If NetSuite costs more at each renewal and your team still keeps spreadsheets beside it, a custom ERP can take over orders, stock, payments and shipping on servers you control. We have done it once already: a US wholesale business moved off NetSuite in about five months, and NetSuite stays read-only for its old records. Send us your NetSuite modules, user count and monthly order volume, and within one business day you get a free written answer: leave, switch package or stay.
When to leave NetSuite, and when to stay.
Cost
The bill grows with every seat
NetSuite’s own ERP pricing guide says cloud licence costs rise as users and modules are added. A custom ERP has no per-user licence: after launch you pay for the server and the changes you ask for, so a new sales rep adds no licence fee.
Fit
Your team works around it
If people re-key orders into spreadsheets, or wait on a consultant for each small change, the package does not match how you work. We build the screens and rules around the way your team already runs.
Lock-in
You want the code and data in your hands
The code lives in your repository and the data in a database on your own server. The scope sets who runs backups and upkeep, and if you change developers later, both stay with you.
Stay if
NetSuite fits once it is set up well
Some teams only need a cleaner NetSuite setup, or a different package such as Acumatica, Microsoft Dynamics 365 Business Central or Odoo. If the setup is the trouble, ask a NetSuite partner to fix it before you pay for a rebuild. The fit check says so in writing, and we do not quote a build you do not need.
One NetSuite replacement, live since July 2026.
We keep the client’s name private. Every figure below comes from the system’s own records. Screens we share use synthetic data.
US wholesale business
From NetSuite to a system it owns
The business ran its wholesale operations on NetSuite. Since the July 2026 go-live, the system we built is its system of record, and NetSuite is kept read-only for history.
- Two apps: an operations app for staff and a sync layer that moves data between tools on a schedule.
- Order entry, card payments, shipping labels, returns, quotes, credit memos, approvals, vendors and tax rates.
- Sales reps work a call queue that shows each customer’s order history.
- Connected to QuickBooks Online for accounting, and to Shopify, whose stock updates every 10 minutes.
- Inventory is valued in FIFO cost layers, and before every release a script checks that on-hand stock equals the open layers.
- It runs on the company’s own server, with separate sandbox and production databases.
Same project · data and cutover
Data checked against NetSuite before the switch
We built the new system while NetSuite kept running, then moved the data and checked it against NetSuite before the switch.
- The team works with the same sales orders, items, vendors and customers it had in NetSuite.
- 27,667 sales-rep attribution records repaired and checked against live NetSuite queries.
- The July 2026 release passed 2,397 automated tests.
- First commit in February 2026, go-live on 3 July 2026: about five months.
We do not name the client in public. Screens we share use synthetic data, never their customers, products or prices.

The order we followed on the NetSuite replacement. Your own schedule is agreed in the scope.
- 1. Map what NetSuite does
- We list the records, saved searches, scripts and integrations the team relies on, and decide which of them are worth keeping.
- 2. Read the data out
- NetSuite has a full CSV export under Setup, Import/Export, Export Tasks, and saved searches and reports export to CSV too. For record-level detail we query NetSuite directly, and scheduled jobs keep the new system in step while both run.
- 3. Build alongside
- Orders, stock, payments and shipping are rebuilt in stages while NetSuite stays the system of record.
- 4. Check, then switch
- The numbers are checked against NetSuite, and a release script confirms that on-hand stock equals the open FIFO layers. On our project the switch came about five months after the first commit.
- 5. Keep NetSuite read-only
- After go-live NetSuite holds the history, read-only, so the team can still look up old records while it works in the new system.
NetSuite alternatives compared, and when each fits.
Pick by how standard your process is.
- Another packaged ERP
- Acumatica, Microsoft Dynamics 365 Business Central, Odoo and Sage are the names on most shortlists. Best when your process is standard and fits with configuration. Watch for a second migration and the same workarounds if the fit is poor.
- Accounting plus an inventory app
- QuickBooks Online with a separate inventory or order tool. Best for a small team with simple stock. Watch for the point where several channels, reps and cost layers depend on one count split across two tools.
- A custom ERP
- Built around your workflow, with no per-user licence, on servers you control. Best when every package you try still forces workarounds. Watch for the higher up-front cost and the longer start: ours took about five months to go live.
Keep NetSuite running until the new system matches.
Free written fit check
Tell us which NetSuite modules you use, how many people log in and roughly how many orders you handle a month. Within one business day we reply in writing: leave, switch package or stay, what we would build first and what discovery costs.
Scoped discovery, then a fixed quote
We map your NetSuite records, saved searches, scripts and integrations, and agree what moves first. You get a written scope, a fixed quote for the build and a schedule before any build starts.
Build alongside, then switch
NetSuite keeps running while we build. We move the data, check it against NetSuite and switch when the numbers match. NetSuite stays read-only for history, and later changes or support run on a care plan or by quote.

Modules, users and monthly orders are enough for the written fit check.

Teams that have outgrown their NetSuite setup.
Wholesale, distribution and multi-channel ecommerce teams that run daily operations in NetSuite and keep spreadsheets beside it. If you only need NetSuite connected to one other tool, say so in the brief. That is a smaller job than a replacement.

Questions we get before people start.
What is the best NetSuite alternative?
It depends on why you are leaving. If your process is standard and the problem is price or setup, another package such as Acumatica, Microsoft Dynamics 365 Business Central or Odoo may fit. A custom ERP is the NetSuite alternative to consider when your workflow does not fit any package without workarounds. The fit check tells you which, in writing.
Is a custom ERP cheaper than NetSuite?
Not always. A custom ERP costs more up front, then has no per-user licence: you pay for the server and the changes you ask for. Discovery ends with a fixed build quote, so you can set it against your NetSuite renewals over several years before you decide.
How do we get our data out of NetSuite?
NetSuite has a full CSV export under Setup, Import/Export, Export Tasks, and saved searches and reports also export to CSV. For record-level detail we query NetSuite directly. In our replacement, scheduled jobs read NetSuite while both systems ran, and we repaired 27,667 sales-rep attribution records and checked them against live NetSuite queries.
What happens to our NetSuite scripts and workflows?
Scripts and workflows built inside NetSuite do not move across as code. We list what each one does, then rebuild that step in the new system, or drop it if nobody uses it.
Can we keep NetSuite during the switch?
Yes. NetSuite stays the system of record while we build, and after go-live it stays read-only for history. On our NetSuite replacement, both ran side by side until the July 2026 switch.
How long does it take to leave NetSuite?
We agree the schedule in the scope. For reference, our NetSuite replacement went from first commit in February 2026 to go-live in July 2026, about five months. That is one project, not a standard turnaround.
What happens to our accounting?
Our NetSuite replacement runs wholesale operations and is connected to QuickBooks Online for accounting. The fit check names the accounting link your setup needs.
Who owns the code and the data?
You do. We work in your repository and on servers you control. Once the work is paid for, the code we write for your project is yours under our terms.
