Introduction
Sales teams rely on accurate customer information, pricing rules, quotations and order history every day. When businesses migrate to a new ERP system, the sales department is often the first to notice data issues. Missing quotations, incorrect pricing, incomplete customer history or inaccurate sales orders can slow down operations, frustrate sales representatives and even result in lost revenue.
A successful ERP migration isn't simply about transferring customer records. It requires careful planning to preserve the complete sales lifecycle from quotations and confirmed orders to pricing structures, customer interactions and historical transactions.
Whether you're migrating from SAP, Microsoft Dynamics, Oracle, Sage, NetSuite, QuickBooks, Zoho, Xero or another ERP system to Odoo, understanding how sales data should be migrated helps ensure business continuity from day one.
This guide explains everything you need to know about migrating Sales Module data, including quotations, sales orders, pricing rules, customer history, discounts, taxes and best practices for achieving a smooth transition.
Why Sales Data Migration Matters
Sales data drives nearly every business function. Finance depends on it for invoicing. Inventory relies on it for stock reservations. Customer support references previous orders. Management uses historical sales to forecast future revenue.
If sales data is incomplete after migration, multiple departments can experience operational disruptions.
Common issues caused by poor sales migration include:
- Lost quotations
- Missing order history
- Incorrect customer pricing
- Wrong tax calculations
- Duplicate sales orders
- Missing discount structures
- Broken customer relationships
- Inaccurate sales reports
Proper migration ensures that sales operations continue without interruption.
What Sales Data Should Be Migrated?
| Data Type | Why It Matters |
|---|---|
| Customers | Maintains customer relationships |
| Products | Ensures accurate order creation |
| Quotations | Preserves ongoing sales opportunities |
| Sales Orders | Supports active fulfilment |
| Pricelists | Maintains customer-specific pricing |
| Discounts | Prevents pricing disputes |
| Taxes | Ensures accurate invoicing |
| Payment Terms | Supports cash flow management |
| Salesperson | Preserves ownership and reporting |
| Customer History | Improves future sales and support |
A complete sales migration typically includes several interconnected data sets.
1. Customer Records
Every quotation and order depends on customer information.
Customer data usually includes:
- Customer Name
- Customer Code
- Billing Address
- Shipping Address
- Contact Details
- Phone Number
- GST/VAT Number
- Payment Terms
- Salesperson
- Customer Category
- Credit Limit
- Preferred Currency
- Language
- Delivery Method
Without accurate customer records, sales documents cannot function correctly.
2. Product Information
Sales orders reference products.
Important product information includes:
- Product Name
- Internal SKU
- Barcode
- Unit of Measure
- Product Category
- Sales Description
- Sales Price
- Taxes
- Variant Information
- Product Attributes
Incorrect product migration leads directly to pricing and invoicing issues.
Migrating Quotations
Quotations represent active sales opportunities.
Many businesses have hundreds or thousands of open quotations when migrating to a new ERP.
These should be migrated with their original status.
Typical quotation data includes:
- Quotation Number
- Customer
- Date
- Valid Until
- Salesperson
- Products
- Quantities
- Unit Prices
- Discounts
- Taxes
- Notes
- Payment Terms
- Delivery Terms
After migration, sales representatives should be able to continue working on existing quotations without recreating them manually.
Migrating Sales Orders
Confirmed sales orders are even more critical because they are linked to inventory, procurement, manufacturing and invoicing.
A migrated sales order should preserve:
- Order Number
- Customer
- Order Date
- Confirmation Status
- Products
- Ordered Quantity
- Delivered Quantity
- Remaining Quantity
- Unit Price
- Discount
- Taxes
- Shipping Method
- Warehouse
- Salesperson
- Customer Reference
Maintaining these relationships prevents disruptions in downstream business processes.
Open Orders vs Completed Orders
| Open Sales Orders | Completed Sales Orders |
|---|---|
| Awaiting Delivery | Fully Delivered |
| Pending Invoice | Fully Invoiced |
| Active Workflow | Closed Workflow |
| Requires Full Migration | Usually Historical Migration |
| Linked to Inventory | Used for Reporting |
| Editable | Read-only History |
Not every organisation migrates historical sales orders in the same way.
Generally, sales orders fall into two categories.
Open Orders
These are still active.
Examples include:
- Awaiting delivery
- Partially delivered
- Waiting for invoicing
- Waiting for payment
These usually need full transactional migration.
Completed Orders
Completed orders have already been delivered and invoiced.
Businesses often migrate them as historical records for:
- Reporting
- Customer history
- Warranty
- Compliance
- Auditing
The migration strategy depends on business requirements.
Pricing Data Migration
| Pricing Component | Migrate? |
|---|---|
| Standard Prices | ✔ Yes |
| Customer Prices | ✔ Yes |
| Volume Discounts | ✔ Yes |
| Promotional Prices | ✔ Yes |
| Currency Pricing | ✔ Yes |
| Pricelists | ✔ Yes |
| Contract Pricing | ✔ Yes |
| Seasonal Pricing | ✔ Yes |
Pricing is one of the most sensitive areas during ERP migration.
Incorrect prices immediately affect revenue and customer satisfaction.
Pricing migration typically includes:
- Standard Sales Prices
- Customer-specific Pricing
- Volume Discounts
- Promotional Pricing
- Seasonal Pricing
- Regional Pricing
- Contract Pricing
- Pricelists
- Currency-based Pricing
Every pricing rule should be validated before the new ERP goes live.
Migrating Customer Specific Pricing
Many organisations negotiate unique prices with customers.
For example:
- Customer A purchases Product X for £95.
- Customer B purchases the same product for £105.
- These pricing agreements must be preserved.
Migration includes:
- Customer
- Product
- Special Price
- Minimum Quantity
- Effective Date
- Expiry Date
Failing to migrate these agreements often leads to customer disputes.
Discount Structures
Businesses frequently use complex discount models.
Examples include:
- Percentage Discount
- Fixed Amount Discount
- Product Discount
- Category Discount
- Customer Discount
- Seasonal Discount
- Promotional Campaigns
All discount logic should be tested after migration.
Tax Configuration
Sales orders calculate taxes automatically.
Migration should preserve:
- Tax Codes
- VAT Rates
- GST Rules
- Country-specific Taxes
- Tax Mapping
- Tax Groups
- Tax Exemptions
Even minor tax errors can create accounting discrepancies.
Salesperson Assignment
Many organisations measure performance by salesperson.
Migration should retain:
- Salesperson
- Sales Team
- Territory
- Commission Group
- Department
This ensures sales reports remain accurate.
Customer History Migration
| Historical Record | Business Value |
|---|---|
| Previous Quotations | Sales Follow-up |
| Sales Orders | Purchase History |
| Invoices | Financial Reference |
| Payments | Credit Evaluation |
| Returns | Warranty Tracking |
| Credit Notes | Customer Service |
| Purchased Products | Upselling Opportunities |
Customer history is one of the most valuable assets during migration.
Sales teams rely on historical information for:
- Repeat Sales
- Customer Relationships
- Pricing Decisions
- Support Requests
- Upselling
- Cross-selling
Historical records typically include:
- Previous Quotations
- Sales Orders
- Invoices
- Credit Notes
- Payments
- Product Purchases
- Returns
Complete history provides better customer service after migration.
Order Line Migration
Each sales order contains detailed line items.
Typical order line information includes:
- Product
- Description
- Quantity
- Unit Price
- Discount
- Tax
- Warehouse
- Delivery Date
Every order line should be validated independently.
Delivery Information
Sales orders often contain shipping information.
Migration includes:
- Shipping Address
- Delivery Method
- Carrier
- Shipping Cost
- Delivery Date
- Tracking Reference
This helps fulfilment teams continue processing existing orders.
Payment Terms
Customer payment terms directly impact cash flow.
Examples include:
- Immediate Payment
- Net 15
- Net 30
- Net 60
- Custom Payment Terms
Incorrect payment terms can delay collections.
Currency Migration
International businesses frequently sell in multiple currencies.
Migration should preserve:
- Transaction Currency
- Exchange Rate (where applicable)
- Customer Currency
- Multi-currency Pricelists
This maintains financial accuracy and reporting consistency.
Attachments and Documents
Sales teams often attach supporting documents to quotations and orders.
Examples include:
- Contracts
- Technical Specifications
- Product Catalogues
- Signed Quotations
- Purchase Orders
- Drawings
Migrating these attachments provides complete context for future interactions.
Notes and Internal Communication
Many ERPs store internal sales notes.
Examples include:
- Customer Preferences
- Negotiation History
- Special Instructions
- Delivery Notes
- Internal Comments
These notes help sales teams continue customer conversations without losing valuable information.
