OBO Meaning: What OBO Stands For and How to Use It (Or Best Offer, On Behalf Of, and More)

OBO usually means “or best offer.” It appears in classified ads, Facebook Marketplace listings, Craigslist posts, and used car ads to tell buyers that the price is negotiable. A seller who writes “$200 OBO” is naming a starting price while inviting lower offers.

The letters OBO also stand for other things depending on where you see them. In banking and legal documents, OBO can mean “on behalf of.” In corporate and securities filings, it can mean “objecting beneficial owner.” This guide covers every common meaning, so you can tell which one applies to what you’re reading.

OBO Meaning: The Short Answer

In most everyday contexts, especially buying and selling, OBO stands for “or best offer.” It tells a buyer that the listed price is a starting point, not a final number. The seller is open to negotiation and will consider offers below the asking price.

You will see it written in a few common formats:

• $200 OBO
• Price: $6,900 obo
• Asking $7,500, OBO

All three mean the same thing: the number listed is negotiable.

OBO Meaning When Selling: Or Best Offer

OBO means “or best offer,” telling buyers that the seller will accept less than the listed price and is actively inviting negotiation. You will run into it on eBay, Facebook Marketplace, Craigslist, OfferUp, and pretty much every peer-to-peer resale site in the United States. vendoo

Adding OBO to a listing signals two things at once:

1. A starting price. The number is not necessarily what the seller expects to receive.
2. An open door. The seller wants offers and is willing to negotiate rather than hold firm.

OBO vs. a Firm Price

A “firm” price is the opposite of OBO — it means no negotiation, while OBO openly invites counter-offers from buyers. If a listing says “firm” or “price is firm,” don’t bother lowballing. If it says OBO, an offer is expected and welcome. vendoo

Label	What It Signals	Should You Negotiate?
OBO	Seller is open to offers below asking price	Yes, a reasonable offer is expected
Firm	Seller will not accept less	No, asking for a discount is unlikely to work
No label	Unclear; seller’s flexibility is unknown	Ask politely before assuming

OBO Meaning on Facebook Marketplace

OBO shows up constantly on Facebook Marketplace, and it works the same way there as anywhere else. The acronym stands for “Or Best Offer” and indicates that the seller is open to negotiating the listed price. For example, an item listed at $50 OBO suggests the seller will consider offers lower than the initial asking price. uvaldetx

Unlike eBay, Facebook Marketplace does not have a built-in “make an offer” button tied to a formal system. Facebook Marketplace relies on informal, text-based OBO, with no native negotiation tooling, so buyers typically message the seller directly with their offer through Messenger. vendoo

Quick tip: When you see “obo” in a Facebook Marketplace listing, a polite opening message might be: “Hi, is this still available? Would you consider $X for it?” Keep the tone friendly. Sellers respond better to reasonable, respectful offers than to blunt lowball numbers.

OBO Meaning on a Car Listing

Used car listings use OBO the same way. OBO means “or best offer” and typically indicates that the seller who posted the listing is flexible and open for negotiation. Marking a car sale as OBO may also show that the seller could be looking to get rid of the car quickly, which a buyer may be able to leverage. chase

An OBO car listing means the seller is willing to go lower than their listing price if needed, even while still hoping for the best possible offer. That last part matters: “best” does not always mean “highest.” capitalone

The best offer isn’t always the highest one. A seller with two offers might take a slightly lower price if that buyer can take the car that same day, rather than waiting a week for a higher bidder — or one buyer needs financing while another can pay cash right away. Each seller decides what “best” means for their own situation, whether that’s speed, convenience, or total price. capitalone

How to Negotiate an OBO Car Price

• Research the fair market value for the make, model, and mileage before making an offer.
• Start with a respectful number, not an insulting one.
• Mention if you can pay in cash or complete the sale quickly — sellers often value that.
• Remember that a private seller has no obligation to accept any offer, no matter how good it seems.

OBO Meaning on eBay

eBay has a more structured version of OBO. eBay’s native “Best Offer” tool lets buyers submit offers while the seller sets auto-accept and auto-decline price thresholds, and offers expire after 48 hours if the seller doesn’t respond. vendoo

A common question is whether the phrase is “or best offer” or just “best offer” on eBay. The feature is officially called “Best Offer,” and it works as a two-way negotiation tool: the buyer submits a number, and the seller can accept, decline, or counter it.

What counts as a fair opening offer on eBay? There’s no universal rule, but staying within roughly 10 to 15 percent below the asking price is a common, reasonable starting point for a first offer.

OBO Meaning in Business, Banking, and Finance

Outside of resale listings, OBO commonly stands for “on behalf of.” This shows up in banking, asset management, and trust services. An OBO account is one where funds are managed on behalf of a specific client, which is common in asset management and trust services. faisalkhan

This is different from a related term, FBO. An FBO, or “For Benefit Of,” account refers to a custodial structure where a bank holds funds on behalf of a company’s customers, without that company having legal ownership of the funds — the goal is to shield the company from complex money-transmitter licensing requirements. A third related structure, an omnibus account, pools multiple clients’ funds together in one account without segregating them individually. faisalkhanfaisalkhan

Term	Stands For	Typical Use
OBO	On Behalf Of	Funds managed for one named client, common in trust and asset management
FBO	For Benefit Of	Bank holds funds for a fintech’s end users without owning them
Omnibus	(Not an acronym)	Broker pools many clients’ funds together without individual segregation

If you see “OBO” written before a name on a payment, invoice, or account document, it usually means the transaction or account is being handled on behalf of that named person or entity, not by them directly.

OBO Meaning in Legal and Corporate Contexts

In corporate and securities law, OBO can stand for “objecting beneficial owner.” An OBO refers to a non-registered shareholder who has objected to their nominee (such as a broker) disclosing their ownership information to the company whose shares they hold. lawinsider

This term matters mainly to shareholders and companies dealing with proxy voting and annual meetings. It distinguishes:

• NOBO (Non-Objecting Beneficial Owner): A shareholder who allows their identity to be shared with the company.
• OBO (Objecting Beneficial Owner): A shareholder who has specifically asked that their identity stay private.

You’ll also see “OBO” used as a shorthand in some government and municipal contracts to refer to an office by its own acronym, so always check the specific document for a defined-terms section before assuming which OBO applies.

OBO Meaning in Construction and Government (Philippines)

In the Philippines, OBO commonly stands for the Office of the Building Official. The Office of the Building Official implements the National Building Code of the Philippines, its implementing rules and regulations, and local city ordinances. Its responsibilities include issuing and supervising building permits for industrial, commercial, residential, institutional, and recreational structures, along with permits for demolition, excavation, electrical work, and signage. tanauancitytanauancity

Under the National Building Code, no one can legally begin construction, major renovation, or demolition in the Philippines without a building permit issued by the local Office of the Building Official. The permit confirms the design follows the Building Code, the National Structural Code, and local fire, sanitation, and zoning rules. aedoconstructionaedoconstruction

While the National Building Code applies nationwide, each local government unit’s Office of the Building Official sets its own checklist, fee schedule, and processing steps, so requirements can vary by city or municipality. aedoconstruction

OBO as a Nickname: Davido’s “OBO”

In pop culture, especially Afrobeats, “OBO” is closely tied to the Nigerian singer Davido. Davido is popularly known as “Omo Baba Olowo,” shortened to OBO, after the title of his 2012 debut studio album, which translates to “Child of a Wealthy Person.” Fans and headlines often use “OBO” as a direct nickname for the artist himself. entrepreneurs

This meaning has nothing to do with negotiating a price. It’s a stage name built from a Yoruba phrase, and it only makes sense in the context of Nigerian music and entertainment coverage.

Is OBO a Noun, a Verb, or Something Else?
