For many growing businesses, procurement complexity doesn’t come from lack of vendors, it comes from choosing the right vendor every single time.

When multiple suppliers offer different prices, quantities, and lead times, the vendor selection process in Odoo can quickly become manual, inconsistent, and dependent on individual buyers.

This is exactly the gap we addressed while working on a real client project and the solution is broadly applicable across manufacturing, distribution, and dropship-heavy businesses.

The Reality of Supplier Selection Process in Day-to-Day Operations

In a typical purchasing or replenishment flow, teams face questions like:

  • Which supplier can fulfill the full quantity?
  • Should we prioritize price or delivery speed?
  • Can we avoid splitting orders across vendors?
  • How do we handle fluctuating stock availability?

Most ERP systems leave these decisions to users, turning the supplier selection procedure into a repetitive and error-prone task.

What businesses actually need is not more data, they need clear processes that reflect how they already think.

This blog will help you detrermine ways to manage Vendor Selection in Odoo.

Efficient Ways to Manage Vendor Selection Process in Odoo

A Rule-Based Vendor Selection Approach

Instead of manual comparison, the system applies a rule-based vendor selection strategy.

You simply need to define:

  • What matters most (quantity, price, lead time, or consistency)
  • The order in which those rules should be evaluated
  • How vendors should be evaluated

Once configured, the vendor selection process in Odoo runs automatically whether the Purchase Order is created manually or generated via MTO or replenishment.

How the Supplier Selection Procedure Works in Practice

Quantity-First Decisions

When fulfilling the full order matters more than unit cost, vendors that can supply the complete quantity are prioritized, even if cheaper suppliers exist with limited availability.

This reduces:

  • Partial deliveries
  • Follow-ups
  • Operational friction

Quantity → Price Decisions

If multiple suppliers can fulfill the required quantity, price becomes the deciding factor.

The system naturally narrows the choice without buyers needing to compare numbers manually.

Vendor Consistency & Consolidation

One of the most impactful aspects of this approach is vendor consistency.

If a single supplier already qualifies for one product line, the system prefers that supplier for other lines as well, even if another vendor is marginally cheaper.

This:

  • Reduces vendor fragmentation
  • Simplifies logistics
  • Improves long-term supplier relationships

The supplier selection procedure prioritizes operational efficiency over micro-optimization.

Real Business Scenarios of Smart Vendor Selection Process in Odoo

Scenario 1: Quantity Comes First

You need 20–30 units of multiple products.

Some vendors are cheaper but can’t fulfill the full quantity.
Others can fulfill everything but at a slightly higher price.

Result:
The system selects vendors who can fulfill entire quantities, even if they’re not the cheapest.

Why this matters:

  • Fewer partial shipments
  • Less follow-up
  • Cleaner procurement

Scenario 2: Quantity → Then Price

When multiple vendors can fulfill the quantity, price becomes the deciding factor.

The system automatically:

  • Filters by sufficient quantity
  • Picks the best-priced option next

Buyers don’t need to compare quotes manually; the logic is already defined.

Scenario 3: Vendor Consistency (This Is the Game Changer)

This is where most systems fail and where real businesses benefit the most.

Imagine:

  • Vendor A supplies Product 1 best
  • Vendor B is slightly cheaper for Product 2
  • Vendor A can still supply Product 2, just at a marginally higher price

Instead of splitting vendors, the system prefers Vendor A for both products.

Why?

  • Fewer vendors per PO
  • Lower coordination effort
  • Better negotiation power
  • Cleaner logistics

This is vendor consolidation logic- prioritizing operational efficiency over micro price differences.

Scenario 4: Price-Driven Businesses

For businesses where cost is king, price can be the top rule.

The system:

  • Picks the lowest total price
  • Uses quantity or lead time only if prices are tied
  • Still prefers a single vendor if rates are comparable

You get the best commercial outcome without sacrificing control.

Scenario 5: Lead Time-Critical Orders

Some orders are time-sensitive.

In these cases:

  • Vendors with shorter lead times are preferred
  • Price and quantity act as tie-breakers
  • Vendor consistency still applies when logical

This is ideal for:

  • Urgent customer orders
  • Service-level commitments
  • Dropship-heavy operations

What Happens During Sales? – Auto Dropship Fits In

Now let’s connect this to sales. When a Sales Order is confirmed:

  • If stock is available → standard delivery flow
  • If stock is unavailable → the system automatically assigns auto dropship for that product line

Vendor selection follows the same rule-based vendor selection logic, ensuring consistency across procurement and fulfilment.

Each product line is handled independently, meaning:

  • No partial splits
  • No manual routing decisions
  • Clear accountability

Auto Dropship + Auto PO Confirmation

For dropship scenarios, the system goes one step further.

Once a Purchase Order is generated from a dropship Sales Order line:

  • It is auto-confirmed
  • No RFQ waiting
  • No manual approval delays
  • Vendor receives the order instantly

This makes auto dropship a truly hands-free process while preserving all standard Odoo tracking and controls.

Business Impact of an Intelligent Vendor Selection Process

The vendor selection process in Odoo should not rely on tribal knowledge or last-minute judgment calls.
