The correct choice for modern US English is vendor.
Use vendor when you mean a person, company, or business that sells goods or services. Vender is a real spelling variant, but it is rare today. In most modern writing, it looks old-fashioned, unusual, or simply like a typo.
So the safe answer is simple: write vendor, not vender, unless you are copying a source that already uses vender.
Quick Answer
Vendor is the standard spelling in everyday US English.
Vender can mean the same thing, but it is not the usual modern spelling. Some dictionaries record it as a variant, especially in commerce or legal contexts, but it is not the spelling most readers expect.
Write:
Correct: The company chose a new software vendor.
Avoid: The company chose a new software vender.
For emails, contracts, invoices, event forms, procurement notes, and business writing, vendor is the better choice.
Why People Confuse Them
The confusion makes sense. English has many nouns for people that end in -er, such as teacher, builder, buyer, and seller. Since a vendor sells things, vender looks like it should follow that pattern.
But English spelling does not always follow one pattern. In modern use, the standard spelling settled on vendor with -or.
Another reason people mix them up is the verb vend, which means “to sell.” A person who vends something could look like a vender by spelling logic. Still, standard modern writing uses vendor.
Key Differences At A Glance

Are They the Same Word?
Yes. Vender and vendor refer to the same basic word: a seller.
The usual meaning is a person or company that sells something. A street vendor sells food or goods. A software vendor sells software or related services. A vendor in a contract is the party selling something.
There is no useful modern meaning difference between vender and vendor for everyday US writing. The difference is spelling preference and reader expectation.
A compact comparison:
• Vendor: standard modern spelling
• Vender: rare variant spelling
• Meaning: same basic meaning, “seller”
• Best everyday choice: vendor
• Best professional choice: vendor
US vs UK Preference
This is not like color vs colour. There is no strong modern split where US English prefers one spelling and UK English prefers the other.
Both US and UK readers normally expect vendor.
That matters because some spelling pairs have a regional answer. This one usually does not. Vender is not the normal British spelling of vendor. It is simply a rare variant that may appear in some records, older material, or special contexts.
For a US audience, the rule is even clearer: use vendor.
Which Spelling Should You Use?
Use vendor almost every time.
Choose vendor in:
business emails
purchase orders
contracts
vendor forms
event planning
food service writing
software and service agreements
school or workplace writing
Examples:
The event has three food vendors.
Please send the invoice to our approved vendor.
The vendor will provide support for one year.
We need a backup vendor before the launch.
Use vender only when there is a clear reason, such as quoting a document that uses that spelling or discussing the spelling itself.
When One Spelling Looks Wrong
In modern US writing, vender often looks wrong even though it appears in some dictionaries.
That is the key point. A spelling can exist and still be the wrong choice for normal modern use.
If you write vender in a workplace email, many readers may pause. Some may assume it is a typo. In a contract or invoice, it may look less polished because the expected spelling is vendor.
Vendor, on the other hand, looks natural in both casual and formal settings.
Common Mistakes (and Quick Fixes)

Mistake: Thinking vender is the UK spelling

Fix: Remember that the standard noun is vendor.
