ERP software cost in India: what changes a quote

Seyon Labs builds custom software, so we have a commercial interest in this topic. This guide focuses on how to compare scope and proposals; it does not present market survey data or a guaranteed price.

What changes a software estimate?

Scope areas that commonly affect effort

Area	Questions to settle
Workflows	Which user journeys must work at launch? What exceptions, approvals and reversals are required?
Roles	Which permissions and screens differ by role? Who can approve, edit, export or view sensitive records?
Locations	How many branches, counters, departments or godowns need separate records and shared reporting?
Integrations	Which external systems or devices need to exchange data? Are stable APIs available, and who pays third-party fees?
Migration	What records move from spreadsheets or older software? Who cleans and validates the opening data?
Connectivity	Must a workflow continue offline? Which data is available and how does it sync safely after reconnection?
Operations	Who hosts and monitors the software? What backup, support, training and recovery commitments are included?

Separate the first release from later improvements

Start with the smallest complete workflow that fixes a real operational problem. For a distributor, that might be purchase receipt through stock allocation and sales order. For a retailer, it may be checkout, returns and shift close. For a clinic, it may be registration, appointments, records and billing.

Write a separate list for improvements that can wait: more dashboards, secondary integrations, additional branches or less frequent edge cases. Phasing makes it easier to validate the first workflow with staff before expanding the scope.

What a written proposal should say

• Which users, workflows, screens and reports are included in each phase.
• Which integrations, devices, data migration, testing and training are included—or excluded.
• What hosting, backups, security updates and post-launch support cover.
• How acceptance is measured, what the timeline assumes and how scope changes are approved.
• Which source code, designs, data and documentation you own or license, and what happens at exit.
• Recurring charges, third-party fees and the cost of future changes.

Be cautious of a one-line total without deliverables, assumptions or a change process. That number cannot be compared with a detailed proposal.

Use one scope to compare proposals

1. Describe one important workflow from start to finish.
2. List the user roles and what each role can see or change.
3. Name the integrations, devices, locations and records to migrate.
4. State how testing, launch support, training and acceptance will work.
5. Ask each vendor to quote the same first release and list exclusions separately.

For a longer-term comparison, include recurring licences, setup, support, training, workarounds, maintenance and exit effort over the same period. Our guide to custom software versus SaaS explains that comparison.

When custom software may not be the right call

If an established product already covers your workflow, staff can use it without harmful workarounds, and its integrations and support are acceptable, a ready-made subscription may be the lower-risk choice. Custom software carries ongoing responsibility for hosting, maintenance and decisions about future changes. Choose it because a defined business need justifies that responsibility, not because “custom” sounds more advanced.
