The short answer: move the process that causes a recurring, material bottleneck and can be implemented within a clear, testable scope. Depending on the company, that may be approvals, invoicing, inventory movements, collections, or expenses. There is no universal first process.
Excel can remain useful for analysis and one-off reviews. The issue begins when a spreadsheet becomes the main operating system for work that crosses teams, requires approvals, or depends on controlled access and reliable status tracking.
Why moving everything at once creates avoidable pressure
Processes do not have equal business impact or implementation readiness. A broad first phase forces teams to clean more data, settle more policy questions, and learn more workflows before they have validated a single operational outcome.
A phased start gives the company a working scope to test. It also makes data migration, training, integration, and support decisions more specific.
Five signals for choosing the first process
1. People ask for its status every day
Repeated questions about an approval, invoice, order, or available quantity usually point to a tracking gap.
2. It depends on several files or channels
Every handoff between spreadsheets, messages, and email increases the risk of stale data and unclear ownership.
3. Delays affect customers, cash, or delivery
Prioritize operational impact over spreadsheet size. A small process can still block invoicing, collection, purchasing, or fulfilment.
4. The team can describe the process and its owners
A painful process may still be a poor first choice if nobody agrees on its steps, exceptions, or source data. Clarify those points before configuration.
5. It can be tested in a controlled scope
A process that can launch with one team, branch, or request type gives the business room to validate data, access rights, and support procedures.
A practical prioritisation matrix
Score each candidate from 1 to 5, then review the top two with management and operational users.
| Criterion | Question | Suggested weight |
|---|---|---|
| Business impact | Does delay affect customers, cash, delivery, or management decisions? | 30% |
| Frequency | Is the process used daily or weekly? | 20% |
| Manual effort | How much re-entry, searching, and follow-up does it require? | 20% |
| Data readiness | Are the source, owner, and required fields understood? | 15% |
| Testability | Can the company launch a small scope and measure it? | 15% |
The score supports a decision; it does not replace judgement. A high-impact process may first need a data-cleaning workstream if its records and ownership remain unclear.
Choosing between common starting points
- Approvals: start here when requests stall, approval limits are unclear, or status depends on private messages.
- Invoicing: consider this first when handoffs delay billing or collections and finance lacks a clear view of invoice status.
- Inventory: prioritise it when uncertain quantities disrupt sales, purchasing, or delivery across locations.
- Expenses: begin here when supporting documents, reviews, or allocations are fragmented and reporting arrives late.
These are diagnostic patterns, not fixed rules. The right answer depends on the company's operating model and implementation dependencies.
First-process readiness checklist
- Process start, finish, owner, and participants are agreed.
- The current files and authoritative data source are identified.
- Required fields, duplicates, and missing records have been reviewed.
- Approval steps and common exceptions are documented.
- Create, edit, view, and approve permissions are defined.
- A realistic pilot sample includes at least one exception.
- A small set of success measures is agreed.
- Users know where to get support after launch.
How the choice affects migration and training
A defined first process narrows data migration to the records required for real work. Training can then follow actual roles and tasks instead of presenting every Odoo application at once.
It also gives the implementation team evidence for configuration, integration, and customisation decisions. Those decisions should follow a review of the business process and a test of the agreed scope.
Who should set the priority?
Management should assess the effect on cash, customers, control, and decision-making. Operational users should identify repeated manual work and failure points. The implementation team should review data and system dependencies. A strong first process combines meaningful business impact, a problem users recognise, and a scope that can be tested responsibly.
Frequently Asked Questions
Must we stop using Excel when Odoo starts?
No. Excel may remain useful for analysis or temporary reports. The operational process should, however, have a clearly agreed system of record to prevent conflicting versions.
What is usually the best first process?
Approvals, invoicing, collections, and inventory are common candidates, but the decision should reflect business impact, data readiness, and testability.
Can priorities differ between companies?
Yes. Sector, company size, branches, responsibilities, and current bottlenecks all affect the order.
Should management or operational users decide?
Both should participate. Management evaluates impact, users explain daily friction, and the implementation team checks dependencies.
When is the selected process ready to go live?
When its steps, ownership, data, permissions, and key exceptions are clear; a realistic pilot succeeds; and users understand both the process and the support route.
Call to Action
If your company is considering a move from Excel to Odoo, begin with the first operational bottleneck rather than a list of every desired feature. Ask Neyar Solutions for an initial business process review to prioritise a practical first phase.
