Managing invoices for numerous deliveries can become time-consuming, especially when a customer order is fulfilled through multiple shipments. The Single Invoice from Multiple Delivery/Shipment (Picking) Odoo App simplifies this process by allowing users to create a single consolidated invoice from multiple delivery orders or incoming shipments with just a few clicks.
Instead of generating separate invoices for each delivery, users can select multiple completed pickings and combine them into a single invoice. This reduces administrative effort, improves billing accuracy, and provides customers with a clear and organized invoice.
The application supports both outgoing deliveries and incoming shipments, making it suitable for sales as well as purchase-related operations.

Why Use Single Invoice from Multiple Pickings?
Many businesses dispatch products in several shipments due to stock availability, warehouse locations, or customer requirements. Creating separate invoices for every shipment can result in:
- Increased accounting workload
- Multiple invoices for a single customer transaction
- Difficult payment reconciliation
- Higher chances of billing errors
- Poor customer experience
This module eliminates these challenges by enabling invoice consolidation directly from selected pickings.

Common Challenges Solved by the Single Invoice from Multiple Pickings App
Many organizations face operational challenges when managing deliveries and invoicing separately. A customer order may be delivered in multiple batches because of inventory shortages, backorders, warehouse transfers, or customer-specific delivery schedules. In such situations, creating separate invoices for every shipment can lead to unnecessary administrative work and confusion.
The Single Invoice from Multiple Pickings App helps businesses overcome these challenges by consolidating multiple deliveries into a single invoice. This ensures better control over billing operations while reducing the workload for sales and accounting teams.
Some common problems solved by this application include:
- Multiple invoices for a single customer order.
- Increased accounting workload due to repetitive invoice creation.
- Difficulty tracking payments against several invoices.
- Customer confusion caused by receiving numerous invoices.
- Delays in billing and payment collection.
- Manual consolidation of shipment information.
By automating invoice generation from multiple pickings, organizations can focus on business growth rather than repetitive administrative tasks.
Streamline Customer Billing Operations
Efficient billing is critical for maintaining healthy customer relationships and ensuring steady cash flow. When customers receive several invoices for one order, payment processing can become complicated. Customers may need additional clarification regarding which invoices belong to which deliveries.
With consolidated invoicing, businesses can provide a professional billing experience. Customers receive a single document that contains all delivered products and shipment details, making it easier to review, approve, and process payments.
Benefits include:
- Faster invoice approval.
- Reduced billing disputes.
- Improved customer satisfaction.
- Simplified payment processing.
- Better visibility into delivered products and services.
Improve Accounting Efficiency
Accounting teams often spend considerable time managing invoices generated from multiple shipments. Every additional invoice requires validation, tracking, reconciliation, and follow-up.
The module helps accounting departments by reducing the number of invoices that need to be processed and managed. Fewer invoices mean fewer accounting entries, less reconciliation effort, and improved reporting accuracy.
Key accounting advantages include:
- Reduced invoice volume.
- Faster month-end closing.
- Easier payment matching.
- Improved accounts receivable management.
- Enhanced financial reporting.
Increase Operational Productivity
Warehouse teams, sales representatives, and accounting departments often work together during order fulfillment and invoicing. When these processes are disconnected, operational inefficiencies arise.
This module creates a smooth connection between inventory operations and financial processes. Users can move directly from completed deliveries to invoice creation without manually collecting shipment information.
As a result, businesses experience:
- Faster processing times.
- Reduced manual intervention.
- Improved workflow automation.
- Better collaboration across departments.
- Increased employee productivity.
Perfect for Businesses with Partial Deliveries
Partial deliveries are common across many industries. Businesses frequently ship available products immediately while remaining products are delivered later. Without invoice consolidation, each shipment may generate a separate invoice.
This application is especially valuable for:
Wholesale Distributors
Wholesale companies often fulfill large orders through multiple deliveries. Consolidated invoicing helps maintain accurate customer billing records.
Manufacturing Companies
Manufacturers may complete production in stages and ship products as they become available. A single invoice simplifies customer billing.
Retail Chains
Retail organizations supplying products to multiple branches can combine shipment information into one invoice for easier accounting.
E-commerce Businesses
Online stores managing inventory across several warehouses can consolidate deliveries into one invoice for a better customer experience.
Trading and Import Companies
International and domestic trading companies frequently receive and dispatch goods in multiple shipments. Consolidated invoicing improves operational efficiency.
Enhanced Visibility and Control
Business managers require clear visibility into invoicing activities and delivery performance. Consolidated invoices provide a complete overview of delivered products associated with a customer transaction.
This enables organizations to:
- Monitor order fulfillment status.
- Review delivered quantities.
- Track invoicing activities.
- Improve customer communication.
- Generate more meaningful business reports.
Managers can quickly understand which deliveries have been billed and which are pending, helping them make informed business decisions.
Reduce Invoice Errors and Duplicates
Manual invoice preparation often increases the risk of mistakes such as:
- Duplicate invoices.
- Missing delivery lines.
- Incorrect quantities.
- Wrong customer references.
- Pricing inconsistencies.
Since invoice data is generated directly from selected pickings, the risk of human error is significantly reduced. Automated consolidation ensures that all relevant delivery information is included in the invoice accurately.
