ERP software cost & ROI for large enterprises
With hundreds of users, per-seat fees for SAP or Oracle NetSuite add up fast across several years. This estimator models the cost and ROI of building your own ERP software to support the decision. The figures are budgeting estimates, not an actual invoice.
ERP software cost & ROI for large enterprises
Large enterprises usually pay for ERP by the seat, so cost swells as headcount grows. A custom build concentrates spend in the development phase and then stabilises, which is why ROI becomes clear after a few years of use. AI lets TOT cut 35-50% of the effort on heavy modules like receivables, management reporting and integrations. Because ERP holds customer and employee data, a custom system must comply with Decree 13/2023 and Decree 70/2025 on e-invoicing. The tool includes a reference price list for each AI plan; these are budgeting estimates, and for a detailed quote on your ERP software TOT scopes it first.
Frequently asked questions
How much does a custom enterprise ERP cost?
Cost depends on module count and how deeply it integrates with existing systems. The tool converts scope into person-months and AI tokens for a quick estimate; the final figure is set after TOT reviews your scale and processes.
How long until it pays back versus renting SAP or Oracle NetSuite?
The break-even point depends on seat count and annual fees. With hundreds of users, cumulative rental usually exceeds a custom build after a few years; the tool lets you build a 3-5 year scenario to compare.
What are the risks of building ERP at enterprise scale?
The main risks are scope creep and complex integrations. TOT phases delivery by module, shipping the core first, and designs access control, encryption and logging under Decree 13/2023 because customer and HR data is sensitive.
How accurate is the ROI figure?
It is a reference model based on module scope and AI productivity ranges, not a financial commitment. Enter your real seat count and rental fees so the scenario matches your enterprise.
Is there a detailed price list and quote for ERP software?
The tool gives a cost estimate with a reference price list for each AI plan. It is not an official quote — for a detailed quote on your ERP software (by scope, features and integrations), contact TOT to scope it.
