ERP Requirements Document for Odoo: Template, Priorities and Sign-Off

Most ERP projects that go over budget did not fail at go-live. They failed months earlier, when nobody wrote down what "done" meant. Our Odoo consulting services start with an ERP requirements document for exactly this reason.

This guide is for owners, finance leads and operations managers preparing to buy or replace an ERP. It sits before the build; once your requirements are signed, our Odoo implementation checklist takes you from planning to go-live.

What is an ERP requirements document?

An ERP requirements document is a written list of what your business needs the ERP to do, ranked and signed by the people who own each process. It is the reference every quote, configuration choice and test is checked against.

It is not a feature wish list copied from a vendor brochure. Each line describes a business outcome, such as "invoice a customer from a delivered order without re-keying prices," not a screen or a button.

Some teams call it a business requirements document, a requirements specification or, in French, a cahier des charges. The name matters less than three things: it is specific, it is ranked, and it is signed.

Why write an ERP requirements document before choosing Odoo?

You write an ERP requirements document so that partners quote the same scope, and so that scope changes cost money on paper instead of in delays. Without it, every proposal answers a different question.

• Comparable quotes: two partners pricing the same signed list give you numbers you can compare line by line.
• Controlled scope: a signed baseline makes new requests visible, so they can be priced, deferred or dropped.
• Better tests: each requirement becomes a user acceptance test, so go-live is judged against facts.
• Less custom code: writing needs as outcomes exposes how many can be met by standard Odoo.

Odoo's own published implementation methodology starts with a GAP analysis that maps business needs to product features, with a plan and budget, before the kick-off. A requirements document is the input that analysis needs.

ERP requirements template: the sections to include

A good ERP requirements template has ten sections, each short enough that a busy owner will actually read and sign it. Use the table as your outline in Word, Google Docs or a shared spreadsheet.

Section	What goes in it	Who writes it
1. Company context	Entities, countries, currencies, headcount, sites	Owner or CFO
2. Goals and success measures	Three to five measurable outcomes	Owner
3. Current systems	Every tool and spreadsheet in use today	IT or operations
4. Process maps	Quote to cash, procure to pay, plan to produce, record to report	Process owners
5. Functional requirements	One line per need, by area, with priority	Process owners
6. Data and migration	Records to move, years of history, data owners	Finance and operations
7. Integrations	Systems to connect, direction, frequency	IT
8. Reports and KPIs	Reports leaders need, with definitions	Finance
9. Users, roles and access	Users by role, approval rules, segregation of duties	Owner and IT
10. Constraints and sign-off	Budget, deadline, hosting, compliance, signatures	Owner

Write each functional requirement on one row with the same columns: ID, area, requirement as an outcome, priority, owner, current workaround and acceptance test. That last column turns the document into your test plan later.

Keep the language plain. "The system shall support multi-level approvals" is vague; "purchase orders above $5,000 need finance approval before sending" (an illustrative threshold) can be configured and tested.

Odoo requirements gathering: how to run the workshops

Odoo requirements gathering works best as short workshops per process, run by someone who knows standard Odoo well enough to challenge each request. The goal is to capture needs, not to redesign Odoo in a meeting room.

1. Name a decision-maker: one person who can approve or reject scope quickly.
2. List process owners: one owner each for sales, purchase, inventory, manufacturing, accounting and HR as relevant.
3. Walk through real documents: bring last month's quotes, orders, invoices and stock counts, not slides.
4. Map the current flow: draw each process from trigger to result, including spreadsheets and email steps.
5. Write outcomes, not screens: record what must happen and why, then the current workaround.
6. Demo standard Odoo: show how Odoo handles the flow before anyone asks for a change.
7. Rank and review: prioritize each line, then circulate the draft for comments within a week.

Our discovery phase follows this pattern: a process map, a module map of Odoo apps and custom work, and a written diagnostic before any build starts.

Must-have vs nice-to-have: how do you prioritize ERP requirements?

A must-have is something you cannot legally or operationally run without on go-live day; everything else is a should-have or nice-to-have for a later phase. Most first drafts mark far too many lines as must-have.

Priority	Test to apply	Odoo example	When it ships
Must-have	Business stops or breaks the law without it	Correct tax on invoices, stock valuation	Go-live
Should-have	Painful without it, but a workaround exists	Automated reorder rules	Go-live if time allows
Could-have	Saves time but is not urgent	Custom dashboard for sales leads	Phase two
Won't-have now	Agreed out of scope this phase	Customer portal redesign	Backlog

This is the MoSCoW method, and it suits Odoo well. Odoo's methodology says specific development should be approved only when it is needed to run the business, with the rest reviewed after go-live in a second deployment.

There is a good reason to defer. An Odoo forum answer on closing gaps between Odoo and your requirements states that over 60% of initial "needs" are dropped a few weeks after going live, once users find standard features are enough.

Which ERP requirements decide your Odoo plan and hosting?

Some requirements do more than add work: they decide which Odoo plan and hosting you can use. Flag these early, because they change your licence budget.

• Custom modules or Apps Store modules: Odoo's docs say Odoo Online is incompatible with custom modules, so you need Odoo.sh or on-premise.
• Several companies: multi-company is listed on the Custom plan, not Standard.
• Studio changes or integrations: Odoo Studio and the external API are both Custom plan features.
• Light Users: staff who only need limited access may fit the Light User price instead of a full user.

On the Odoo pricing page, US prices billed yearly are US$31.10 per user a month for Standard and US$61.00 for Custom, with first-year prices of US$24.90 and US$49.00. In India they are Rs 725 and Rs 1,350. The Light User is US$8.90.

For integrations, note that XML-RPC and JSON-RPC are deprecated in Odoo 20, with removal scheduled for Odoo 22. New integration requirements should name the newer API, which our Odoo integration services build on.

How do you turn requirements into a fit-gap analysis?

A fit-gap analysis takes each requirement and marks whether standard Odoo meets it, configuration meets it, or a gap remains that needs a decision. It is the bridge between your document and a real quote.

Fit status	Meaning	Typical action
Standard fit	Odoo does it out of the box	Configure and test
Configuration	Settings, rules or Studio fields close it	Configure, document the setting
Process change	Odoo does it differently but reaches the same result	Agree the new process, train users
Gap	Needs a custom module or integration	Estimate, then accept, defer or drop

Push every gap through the same four options in order: change the process, configure, use an existing app, and only then build. Our guide to Odoo Studio vs custom development explains where each option fits.

Gaps also cost you at upgrade time. Odoo supports each major version for about three years under its standard support policy, so every custom module you approve today must be moved to new versions later.

ERP RFP template: using requirements to compare Odoo partners

An ERP RFP template wraps your requirements document with questions about the partner, so every proposal answers the same scope. Send the requirements, not a one-line brief.

Ask each partner to answer every requirement line with a fit status, an effort estimate and an assumption. Add questions on team, method, data migration, training, testing, support and upgrade path, and ask what is excluded.

When proposals come back, score them on the same grid. Our checklist and scorecard for comparing Odoo proposals gives a ready-made scoring model.

Sanity-check totals against published ranges. Our Odoo implementation cost guide puts small projects at $3k to $9k over 4 to 8 weeks, mid-size at $9k to $27k over 8 to 14 weeks, and large ones at $27k to $150k+ over 12 to 24 weeks.

How do you get ERP requirements sign-off, and what happens after?

Requirements sign-off means one accountable owner approves the document as the project baseline, and every later change goes through a written change request. Without that, the document is only a draft.

1. Circulate the final draft: give process owners five working days to comment.
2. Hold a review meeting: resolve open questions and confirm each priority.
3. Sign and version it: the decision-maker signs version 1.0, with the date.
4. Freeze the baseline: later requests are logged, not slipped in.
5. Price each change: effort, cost and timeline impact before approval.

Odoo's methodology takes the same line: changes are generally not accepted in a running cycle unless the deadline and budget are unaffected, and a new requirement may be accepted only if another is dropped.

ERP requirements checklist by industry

The core template is the same for every business, but each industry adds requirements that are easy to miss. Use the table to add the lines your sector needs.

Industry	Pain or cost driver	Odoo approach	How iVentureTeam helps
Manufacturing	Bills of materials, routings, scrap	Odoo Manufacturing, Quality, PLM	Map production flows into requirements
Wholesale and distribution	Multi-warehouse stock, landed costs	Inventory routes, barcode, purchase rules	Define warehouse and reorder requirements
Retail and eCommerce	Channels out of sync with stock	POS, eCommerce and Inventory in one database	List channel and sync requirements
Professional services	Time not billed, project margins unclear	Project, Timesheets, Invoicing	Specify billing rules and approvals
Multi-country groups	Several entities, taxes and currencies	Multi-company on the Custom plan, localizations	Capture tax and intercompany needs per country

Common mistakes in ERP functional requirements

The most common mistake in ERP functional requirements is describing today's workarounds as if they were needs. These are the patterns we see most often.

• Copying the old system: writing down every screen of the current tool instead of the result each step delivers.
• Everything is a must-have: if 80% of lines are must-haves, nothing is prioritized.
• No owner per line: requirements without an owner never get answered or tested.
• Ignoring data: no decision on how many years of history to move or who cleans it.
• Vague reports: "a sales report" instead of the exact columns, filters and definitions.
• No acceptance test: if you cannot test a line, you cannot sign it off at go-live.

For data scope, Odoo's import and export documentation shows what clean import templates look like, which helps owners decide what to bring across.

ERP requirements document case study: KMF Technologies

KMF Technologies, an IT services and hardware firm in The Gambia, started its Odoo project with requirements before any configuration. The project ran in seven phases, from analysis to support.

The company tracked products and categories by hand, had no real-time stock view, and its sales, purchase and store teams could not see each other's data. Customers waited while staff checked with each team.

We ran a structured seven-phase implementation: requirements, system design, configuration, report customization, data migration, training and post-go-live support. Four Odoo apps went live: Sales, Purchase, Inventory and Accounting.

The build covered warehouses, stock locations, role-based access, four custom PDF reports and a chart of accounts for The Gambia. The rollout took 8 weeks in phases. Read the KMF Technologies Odoo inventory implementation case study.

The bottom line on the ERP requirements document

A short, ranked and signed ERP requirements document is the cheapest risk control in any Odoo project. It makes quotes comparable, scope visible and go-live testable.

Start with the ten-section template, run workshops per process, be strict about must-haves, and flag the requirements that decide your Odoo plan. Then sign version 1.0 and route every change through a written request.
