Migrating essential records into Odoo 18 is a vital step when implementing a business management ERP system—whether you're launching a new database, switching platforms, or optimizing existing operations. Key data types like products, customers, vendors, categories, sales and purchase orders, invoices, and bills must be correctly imported to maintain workflow accuracy and business continuity.

This guide will help you understand each master data type's role and demonstrate how to import them into Odoo 18 with precision. We'll walk through everything from preparing import templates in Excel/CSV to validating and uploading your data, ensuring a clean and smooth migration process.

Importing Product Categories

To begin, go to Sales > Configuration > Product Categories. Use the Export option to download an example category. Select relevant fields and choose either XLSX or CSV format. Modify the template to include your new categories, such as “Sample Product Category” under the “All” parent. Save the file and then use Import Records to upload. Test the file for errors before the final import.

Importing Product Variants

First, import product attributes via Sales > Configuration > Attributes. Export a sample attribute file, modify it to include new attributes like “Size” (e.g., Small, Medium, Large), and then import it. After attributes are in place, export an existing product template. Add your new product (e.g., "Top") with attributes and values. Validate and upload the updated file via Sales > Products > Import.

Importing Customers

Navigate to Sales > Orders > Customers. Export a sample customer record. Adjust fields to create new customers like “Customer A.” After saving, upload the file via the Import Records option. Validate and confirm the import to add the customer successfully.

Importing Vendors

Head to Purchase > Orders > Vendors and export an existing vendor to understand the structure. Create a new vendor like “Vendor A” in your file, then import it back into Odoo. Validate and finalize the process to see your new vendor listed.

Importing Sales Orders

Access Sales > Orders > Quotations, export a sample quotation, and use it as a template. For example, add a new order with products like “Top” and “Storage Box.” Use Import Records to upload the modified file. Test the file before import to ensure data consistency.

Importing Purchase Orders

Under Purchase > Orders > Request for Quotation, export an existing RFQ. Update the file with new entries like “Office Chair,” then import it. After validating the data, the purchase order will appear in your system.

Importing Customer Invoices

Go to Accounting > Customers > Invoices, export a sample invoice, and revise it for new data, such as items like “Office Lamp.” Use the Import Records button to upload and validate the file before importing it into Odoo.

Importing Vendor Bills

Visit Accounting > Vendors > Bills. Export a sample bill, modify it with new entries like “Office Chair,” and save the file. Then, upload it via Import Records, validate the file, and import the data to see the new bill reflected in your records.
