Odoo Purchasing: how it works
Requests for quotation, purchase orders and receipt against the order. The real gain is not the purchase order: it is to stop buying what you already had and stop running out of what actually sells.
What does the Odoo Purchasing module do?
iTechDev implements Odoo Purchasing, and most companies that call us about this module do not have a purchase-order problem: they have a problem where nobody sees the same number.
- Request for quotationWhat you send to several vendors before committing. Odoo keeps the replies for comparison.
- Purchase orderThe firm commitment. Goods are received against it and the vendor bill is validated against it.
- Reordering ruleMin and max per product and warehouse. When stock drops below the minimum, Odoo proposes the purchase.
- Lead timeHow long each vendor takes. Without it, proposals arrive late even when the rule is right.
- Three-way matchOrder, receipt and bill agreeing. It is what stops you paying for what never arrived.
See in detail
Odoo handles the full circuit — RFQ to several vendors, comparison, purchase order, receipt against the order and vendor bill against what was received — and the value there is not the paperwork but that purchasing stops working blind. With reordering rules Odoo proposes what to order and when, looking at what is in the warehouse, what is already inbound and what is committed to sales orders. That cuts the two losses that coexist in almost every operation: over-buying what you already had, and running out of what was actually selling. But it depends entirely on inventory being reliable: if stock lies, purchase proposals lie with more confidence, and the damage is worse than not having the module.

When this module solves something
What the module includes
Multi-vendor quoting
Send the same request to several and compare replies in one view before deciding.
Purchase orders
With terms, lead times and approval by amount when you want someone else to authorize.
Reordering rules
Min and max per product and warehouse, accounting for what is already inbound.
Receipt against the order
What was ordered is received, shortages and overages recorded, and inventory updated at that moment.
Three-way control
Order, receipt and vendor bill reconciled, so you do not pay for what never arrived.
Vendor pricing
Price and lead time per vendor and volume, with history to see whether they raised it.
Purchase linked to sale
Products bought when sold, without going through the warehouse, for what you do not want to stock.
Purchasing reports
How much you buy from whom, at what price and with what lead-time performance.
Decisions to make before configuring
1Is inventory reliable?
The entry condition. Without reliable stock, purchase proposals are noise dressed as data, and that is worse than none.
2Who approves and from what amount
The approval flow by amount or purchase type. A management decision; without it, configuration is blind.
3Min and max per product
Someone has to define them, and they come from historic consumption and vendor lead time. Data work, not configuration.
4Real lead times per vendor
The data almost nobody has captured, without which rules arrive late. Gathered at the start.
5Receipt steps
One, two or three, with quality control in between if your industry requires it. More steps, more control, more clicks.
6What migrates from vendors
Vendor catalogue and current prices almost always; full order history rarely pays off.
Tech stack
The tools and platforms we build it with — chosen for your problem, not for hype.
Questions about Purchasing in Odoo

Contact us →Is Purchasing in Community?
Yes, in full: RFQs, orders, reordering rules and receipts. It is not one of the modules that pushes you to Enterprise; what does is the official Mexican accounting that comes after.
Does Odoo tell me what to buy?
Yes, with reordering rules that look at stock, inbound and what is committed to sales. But the quality of that proposal is exactly the quality of your inventory and the lead times you captured per vendor. If those two are wrong, the proposal is wrong with more authority.
Can I compare vendors?
Yes, send the same request to several and compare in one view. And the history remains, which in practice is the most useful part: it shows who raised prices and who meets the lead time they promised.
How do I avoid paying for what never arrived?
Three-way matching: order, receipt and vendor bill must agree. Standard configuration, and one of the fastest to pay for itself if someone reconciles that by hand today.
What about creditable VAT on purchases?
Handled on the accounting side, not in purchasing, and that is where the edition decision comes in: full official Mexican accounting is Enterprise. Purchasing records the tax correctly; what changes between editions are the electronic reports that come later.
How long until it is running?
Configuration is fast. The timeline is set by mins, maxes and vendor lead times, which have to be derived from historic consumption and are almost never documented.
