Odoo Quotation & Expense Mistakes to Avoid

Common Mistakes to Avoid When Using Odoo Quotation and Expense Modules

Common Mistakes in Odoo Quotation and Expense Modules

Odoo’s Quotation and Expense modules are powerful tools that can streamline your sales and expense processes. But like any tool, if set up or used incorrectly, they can cause more headaches than they save. From mis-pricing to lost receipts or confusion over status, here are some of the most common pitfalls that businesses face — and how you can steer clear of them.

Mistakes in the Quotation Module

Default Pricing Gets Overwritten Silently: When you create a quotation and then change the quantity (or some product attribute), Odoo may revert the line item back to the default sales price. This often surprises salespeople who had applied a negotiated discount or custom pricing. Users may send a quote with wrong pricing.
Tip: Use pricelists for special customers or negotiated deals, and test how your quotation template behaves when quantities are changed. Consider customizing behavior if default rollback happens.
Freshly Updated Taxes or Shipping Not Recalculated: After adding or modifying products, users sometimes forget to update taxes or shipping cost. Because these may depend on total order amount or weight, failing to recalc can misstate the final quote.
Tip: Build validation or workflow steps that force recalculation (or at least remind the user) before a quotation is finalized. Use quotation templates that include default shipping terms and always review tax options.
Multiple Duplicate Quotations / Confusing Versions: Sometimes, multiple versions of a quote (due to changes, follow-ups, or reused templates) get created or saved, causing confusion over which is the latest, what was accepted, and what pricing was offered. This can lead to errors or delays in conversion.
Tip: Maintain naming/version conventions, archive obsolete quotations, or use a workflow where only one version remains “active.” Make sure the sales team knows which version is current.
Quotation Templates Not Localized / Language or Terms Not Matching Customer: Using a quotation template that has fixed language or terms that don’t match the customer’s locale can look impersonal, or even cause misunderstandings. For instance, product descriptions or T&C in wrong language, or missing clauses relevant to local policies.
Tip: Maintain different templates if you serve customers in different regions/languages. Test the PDF output to see how the quotation looks from a customer’s perspective.

Mistakes in the Expense Module

Incomplete or Inconsistent Data Entry: Employees submitting expense reports often omit key information (vendor, date, description, attachment/receipt). Sometimes fields aren’t made mandatory, so reports go through incomplete, causing delays or requiring rework.
Tip: Enforce mandatory fields, maybe even customize the expense form to block submission unless all necessary data is filled. Train employees on what details matter (dates, vendor names, amounts, receipts).
Duplicated Expense Claims: Expenses may be submitted more than once by mistake — same receipt, same date, same vendor, etc. Without checks, these duplicates can slip into approvals, costing money and making audits harder.
Tip: Use some kind of duplicate detection (e.g. matching by receipt, amount, date). Regularly review pending claims for possible duplicates.
Wrong Currency / Tax / Accounting Configuration: If the expense module isn’t properly configured for your local tax rules, currencies, or journal entries, the posts to accounting may be wrong. For instance, missing expense journal, wrong tax rates, or mis-mapped account ledgers.
Tip: At setup, verify your expense journal(s), local tax settings, currency conversions, and test with real-like claims. If mistakes are found, fix early before many claims accumulate.
Approving vs Marking Paid Confusion: Some users approve an expense claim but then use separate entries or processes for “payment.” They might manually create payment outside Odoo or forget to mark expense as “paid/in payment.” This leads to reports showing approved expenses that are never paid — or payments recorded twice.
Tip: Define clear workflows: submission → approval → payment → status update. Use Odoo’s built-in payment status rather than patching in your own process. Train finance users to follow the defined path.
Overlooking Workflow Rules or Custom Conditions: Sometimes logic around expense approval (thresholds, manager approvals, exceptions) is not well defined or tested. For example, who approves small vs large expenses? What happens if receipts are missing? These gaps lead to delays or irregular approvals.
Tip: Design workflows with your business policy in mind. Simulate edge cases (no receipt, late submission, high amount). Use testing/staging environment to validate how the module behaves in these “unusual” cases.
Neglecting Reporting, Audits & Dashboards: After going live, many organizations forget to regularly review expense data, run reports (e.g. outstanding claims, cost per department, trends), or monitor dashboards. Without ongoing visibility, issues accumulate — e.g., unclaimed expenses, ballooning travel costs, or non-compliant spending.
Tip: Set up custom dashboards/filters for finance & management. Review periodically. Use insights to refine policies (e.g. cap meal rates, identify frequent expensive vendors, etc.).

Wrapping Up

Mistakes in quotation or expense handling are often not due to bad tools — they happen when processes, training, or configurations aren’t aligned with how people actually work. The good news is, most of these problems can be addressed with a bit of planning, good defaults, clear policies, and user training.
