Odoo 18's Sales app carries a deal from quotation to order to invoice without re-entering anything: a confirmed quotation becomes a sales order, which reserves stock in Inventory and generates the invoice in Invoicing. Quotations are sent as a portal page where the customer can sign online and pay a deposit, and pricelists handle customer-specific and quantity-based pricing. Sales is a Community app.
Whether you're a wholesaler, B2B service provider, or eCommerce seller, managing your sales efficiently is key to growth. The Odoo 18 Sales module simplifies everything — from quoting and order tracking to invoicing and performance analysis.
With a clean interface and full integration across your business, your team can work faster and more accurately, reducing paperwork and increasing revenue.
Creating and Sending Quotations
Odoo makes it simple to send professional, accurate quotations in just a few clicks. From the Sales dashboard, click Create to generate a new quotation.
Highlights of the Quotation feature
- Drag-and-drop product lines for speed
- Customizable templates for recurring quote styles
- Online signature and payment options built-in
- Email tracking so you know when quotes are viewed
Once accepted, you can confirm the quotation into a sales order instantly, streamlining the sales-to-fulfillment process.
Flexible Pricing and Discounting
Need to handle special pricing for VIP clients? Or give quantity-based discounts? Odoo 18 makes pricing powerful but easy.
Key features
- Pricelists to set dynamic or fixed prices by customer segment
- Discount rules (by product, order total, or time period)
- Promotions and coupons (ideal for eCommerce)
- Currency and tax localization based on customer location
This makes it effortless to personalize pricing strategies and boost conversions.
Managing Sales Orders
Once a quotation is confirmed, it becomes a Sales Order. Odoo tracks each order's fulfillment status, invoicing, and delivery status from a centralized dashboard.
Features include
- Automated order workflows for confirmation, delivery, invoicing
- Real-time order status tracking
- Delivery date planning
- Customer communication tools built-in
Every order in Odoo is linked to inventory, accounting, and shipping — keeping all teams aligned.
Product Catalog and Configuration
Your sales team will love how easy it is to manage products in Odoo. You can create product templates with variants (like size, color, or packaging) and set attributes for each item.
Product configuration includes
- Product types: Storable, consumable, or service
- Variant management: With matrix view
- Multiple units of measure
- Barcoding and SKU support
This ensures every quote or order is accurate and inventory levels stay in sync.
Integration with Invoicing and Inventory
One of the biggest strengths of Odoo Sales is its deep integration with other Odoo apps — especially Invoicing and Inventory.
- Sales → Invoice: Generate invoices automatically based on order lines
- Sales → Inventory: Reserve stock and trigger deliveries
- Sales → Subscription: Convert quotes into recurring plans
This allows for a smooth, end-to-end sales process — no double entry, no manual updates.

Questions we get asked
Can customers sign and pay a quotation online in Odoo 18?
Yes. A quotation can require an online signature, an online payment, or both, and the customer does it from the portal link in the email rather than printing and scanning anything. You can ask for the full amount or for a percentage as a down payment. Once the condition is met, Odoo 18 confirms the quotation into a sales order automatically.
How do pricelists work in Odoo 18 Sales?
A pricelist is a set of rules attached to customers. Each rule can fix a price, apply a discount, or compute a formula from the sales price or the product cost, and can be limited to a product, a category, a minimum quantity or a date range. The customer's pricelist applies as you add order lines, and you can still override an individual price.
Can I set an expiry date on an Odoo 18 quotation?
Yes. Every quotation has an expiration date, and a quotation template can fill it in automatically so nobody has to remember. After that date the portal link no longer lets the customer confirm, and the quotation shows as expired in your list so it stops inflating the open pipeline. Extending it is a matter of changing the date and sending it again.
What is the difference between the Sales app and Invoicing in Odoo 18?
Invoicing is the accounting side — customer invoices, vendor bills, taxes and payments — and works on its own. Sales adds everything before the invoice: quotation templates, pricelists, sales orders, delivery and invoicing policies, and the link to Inventory. Both are Community apps, and installing Sales does not replace Invoicing; the sales order simply produces the invoice that Invoicing then handles.
Can Odoo 18 invoice only part of an order?
Yes, and the invoicing policy on the product sets the default. Ordered quantities bills the whole line as soon as the order is confirmed; delivered quantities bills only what has actually shipped, so a partial delivery produces a partial invoice and the rest stays to invoice. You can also raise a down-payment invoice for a fixed amount or a percentage before anything ships.
