ERP software development services and custom ERP development with prices up front
ERP software development services should start with a price, not a sales call. In our estimate model, an inventory and order management ERP costs $66,000 to $94,000 and takes 9 to 12 weeks, a wholesale ERP with quotes, invoicing and an accounting connection costs $70,000 to $104,500, and a custom layer on the NetSuite, Odoo or QuickBooks setup you already pay for starts at $18,500. Pick your modules and see your own range in about a minute, then pay one stage at a time.

Why operations teams hire us for custom ERP development
Most companies that look for a custom ERP development company already run some ERP, or a stack of QuickBooks, spreadsheets and a warehouse app held together by exports. The pain is rarely the general ledger. It is the work your package cannot model: how you quote, how you allocate stock across locations, how a job moves through your shop floor, what your customers need to see without calling you. That is the part worth building.
- 01 A price before you commit. You see hours, team size, timeline and cost per module before any call.
- 02 Stage payments. Discovery costs 10 percent of the estimate, at least $1,900. Design, build sprints and launch are each paid before they start, and you can stop after any of them.
- 03 No per-user license. Adding 30 more people to a custom ERP costs hosting, not another $129 to $199 a seat every month.
- 04 Accounting stays where it belongs. We connect to QuickBooks, Xero or NetSuite for the ledger, payroll and tax, and build the operational modules around it. That keeps your CPA and your audit trail where they are today.
- 05 Your code and your data. Everything lives in your repository and your cloud account, and the rights transfer to you as each stage is paid.
ERP software development services we cover
- 01 New ERP modules. Inventory, purchasing, order management, production, job costing and scheduling, designed around your process instead of a vendor's default objects.
- 02 Custom layers on NetSuite, Odoo, Acumatica or QuickBooks. Dashboards, approval flows, reports and internal tools that read and write through the vendor's API.
- 03 Customer, dealer and vendor portals. Logins for outside users to place orders, see invoices, upload documents and check status, tied to the same records.
- 04 Warehouse and field apps. Scanner and job apps for iPhone and Android with offline mode, built by our mobile app development team.
- 05 Integrations and data migration. Two way sync with accounting, ecommerce, carriers, EDI partners and banks, plus migration from spreadsheets or an older system.
- 06 AI on ERP documents. Invoice and packing slip capture, purchase order matching and search across documents through our AI development work.
- 07 Sales data next to operations. When quotes and accounts belong in the same place, we build the sales side too, as described on our custom CRM development page.
How a custom ERP project runs
-
01
Run the estimate. Pick the project type, the modules and the systems to connect, and see the range in about a minute.
-
02
Discovery and scope, about one week. We walk the floor or sit with your planners and finance team, map the records, roles and approvals, review a sample export of your data, and fix the price of each later stage.
-
03
Design, about two weeks. Screens for every role in scope, from buyers and warehouse leads to the controller, unless you bring your own designs.
-
04
Build in two week sprints. You click through a live build at the end of every sprint and can reorder the backlog between sprints, so the module that hurts most ships first.
-
05
Launch and migration. Production release, data import, a short training session for each team and the code in your account. After launch, our maintenance plans start at $990 a month.
Who buys custom ERP software development from us
- 01 Distributors and wholesalers with 20 to 300 staff whose ERP cannot handle their pricing rules, allocations or customer specific catalogs.
- 02 Small and mid-size manufacturers who track work orders on whiteboards and spreadsheets next to an accounting package.
- 03 Field service, construction and installation companies that schedule crews, track job costs and need photos and documents tied to each job.
- 04 3PLs and companies with their own fleet, often together with our logistics software development team.
- 05 Finance and operations leads whose NetSuite or Odoo bill keeps growing while staff still export to Excel every week.

Here is the honest version. A 15 person company with standard purchasing and fulfillment should buy a packaged ERP and spend its money elsewhere. Custom ERP development wins when per-user fees at your headcount become the biggest line, when the vendor needs a consultant every quarter to fit, or when your process is the reason customers pick you. For many teams the right answer is the middle column: keep the packaged core and build the two or three screens it does badly.
Questions buyers ask a custom ERP development company
In our model, a first version operations ERP costs $57,000 to $75,500, an inventory and order management ERP costs $66,000 to $94,000, and a multi-location ERP with invoicing costs $79,000 to $123,000. A custom layer on an existing ERP costs $18,500 to $34,000. Your own modules give your own range in the estimate.
A first version takes 8 to 10 weeks of build after a one week Discovery. Inventory, wholesale and manufacturing ERPs take 9 to 14 weeks, depending on modules and connections. Teams usually launch one module first, such as inventory, then add purchasing or production in later stages.
Buy a packaged ERP when your processes are standard, your headcount is small and you want accounting, payroll and operations in one place. Build custom ERP modules when per-user fees exceed the cost of owning the code, when your operations do not fit the vendor's model, or when customers use the system directly.
Yes. We build dashboards, approval flows, portals, scanner apps and integrations that work through the NetSuite, Odoo, Acumatica or QuickBooks API, so finance keeps the system it knows. In our model a dashboard, reports and two integrations cost $18,500 to $34,000 and take 4 to 7 weeks.
We advise against it. Rebuilding the ledger, payroll and tax logic is where custom ERP projects run over budget and fail audits. We keep those in QuickBooks, Xero or NetSuite and sync invoices, bills and inventory values into them, so your books stay in a system your accountant already trusts.
You do. The ERP is built in your repository and cloud account, and the rights to each stage transfer to you when that stage is paid. You can bring maintenance in-house or move it to another team at any time.
