You post a pair of sneakers online. Within minutes, the comments start rolling in.
"UP." "LP?" "MOP?" "RFS?"
If you're new to online selling in the Philippines, it can feel like everyone is speaking a different language. In a way, they are.
Over the years, Filipino sellers have developed their own shorthand across Facebook Marketplace, buy-and-sell groups, Instagram, TikTok Shop, and live selling. Knowing what these terms mean helps you respond faster, avoid misunderstandings, and keep buyers from dropping off before they complete a purchase.
This guide breaks down the online selling terms you'll see most often, starting with one of the most common.
What Does "UP" Mean in Online Selling?
Quick answer: In Philippine online selling, "UP" means "under post." It's a comment used to bump a listing higher in Facebook's feed. Every new comment signals activity, making the post more likely to appear in front of other buyers.
Sellers use it to keep listings visible. Buyers use it to save a post they want to revisit later.
Here's why it works.
Facebook groups prioritize recent activity. As older posts get pushed down the feed, even a single comment can make a listing appear active again. Instead of creating a new post, sellers simply comment "UP" to bring it back into circulation.
You'll also come across a few variations:
- UP — the standard bump.
- Pa-up / Up mo — asking someone to bump the post.
- UPP / UUP — the same thing, just with extra emphasis.
- Up for grabs — different meaning entirely. It simply means the item is still available.
Why Buyers Comment "UP"
It's not just sellers.
Many buyers comment "UP" to keep track of a listing. Once they've commented, Facebook sends them notifications whenever the seller replies or updates the post, making it easy to check back without searching for it again.
Some buyers also bump listings so friends or family can see them.
How to Reply to "UP"
Don't waste the opportunity with a simple "Thanks."
Someone just helped put your listing back in front of more buyers. Use your reply to answer the questions people usually ask before they buy.
“Thanks for the up! Still available. LP is ₱2,800. MOP: GCash, Maya, card, or bank transfer. Ships nationwide. You can pay here: [payment link]”
In one reply, you've answered the three questions most buyers ask first and given them a way to check out immediately.
The fewer messages buyers need to send before paying, the more likely they are to complete the purchase.
Filipino Online Selling Terms, Explained
Now that you know what UP means, here's a glossary of the abbreviations and slang you'll see every day, grouped by where they usually come up, from browsing listings to negotiating prices and getting paid.
Buying and Browsing Terms
Item Condition Terms
Price and Negotiation Terms
Payment and Delivery Terms
This is the group that decides whether you actually get your money.
Live Selling Terms
Live selling on Facebook and TikTok moves fast and has its own vocabulary.
MOP Is the Term That Decides Whether You Get Paid
Scroll through any buy-and-sell group and you'll see the same question again and again:
"MOP?"
It stands for Method of Payment. By the time a buyer asks, they've usually decided they want the item. They're asking how to pay.
This is where many online sellers lose the sale. The typical reply looks something like this: a GCash number, a bank account, instructions to send a screenshot, then a wait while the seller checks if the payment arrived.
It works. Until you're handling dozens of orders. Every extra message slows the checkout. Every extra step gives buyers another chance to change their mind.
There's also the trust problem. Sending money to a stranger's personal account isn't something every buyer is comfortable with. Many would rather buy from someone who offers a proper checkout. A checkout page removes the back and forth.
The buyer opens a link, chooses GCash, Maya, cards, QR Ph, or online banking, and pays. You receive the payment automatically. No screenshots to verify, no receipts to match.
How to Accept Different Payment Methods
The best way to collect payments depends on how you sell. If you're on social media, you don't even need a website.
Selling in Facebook comments or DMs? Use Payment Links.
Selling one item at a time? Create a payment link for the exact amount and send it in the conversation.
When someone comments "Mine" or asks "MOP?", reply with the link instead of your personal account details. The buyer pays using GCash, Maya, cards, QR Ph, or online banking, and you're notified as soon as the payment goes through.
It's the fastest option for one-off sales, Facebook Marketplace listings, and live selling.
Selling from your bio or product catalog? Use Payment Pages.
If you regularly sell multiple products, share one permanent payment page instead.
Add it to your Instagram or TikTok bio, pin it on Facebook, or include it in your posts. Buyers can browse your products and check out on their own.
No website required.
Already have a website? Use Hosted Checkout.
If you sell through your own website, redirect buyers to a PayMongo-hosted checkout instead of building your own payment form.
You can accept GCash, Maya, cards, QR Ph, and other payment methods while PayMongo securely handles the payment flow and PCI-DSS compliance.
Using Shopify, WooCommerce, or Wix? Install a plugin.
If your store already runs on an ecommerce platform, install a PayMongo plugin to add GCash, Maya, cards, and QR Ph to your existing checkout. No custom integration required.
Which One Should You Start With?
Most sellers start with payment links, then add a payment page once they're posting inventory regularly.
Stop Losing Sales at “MOP?”
You sourced the item, shot the photos, wrote the caption, and answered the comments. Losing the buyer at the payment step is an expensive way to end that. Accept GCash, Maya, cards, QR Ph, and online banking – no setup fee, no monthly fee. You only pay when you get paid.
Frequently Asked Questions
What is the difference between LP and SRP?
LP is Lowest Price — the least the seller will accept, usually asked by buyers negotiating. SRP is Suggested Retail Price, the original store price, which sellers quote to show how big a discount they're offering.
What does RFS mean and why do buyers ask it?
RFS means Reason For Selling. Buyers ask because the answer often reveals problems — a phone sold because of battery issues, or shoes sold because they don't fit. A vague RFS is a common warning sign in secondhand deals.
Do I need a website to accept online payments in the Philippines?
No. With PayMongo payment links you can send a checkout link straight into a Facebook comment, DM, or Viber chat. If you want a shareable catalog instead, a payment page gives you a storefront-style link with no website required.
Is it safe to accept payments through a payment link?
Payment links route buyers to a secure, PCI-DSS compliant checkout rather than asking them to send money to a personal account. That protects you from receipt-editing scams and gives buyers a reason to trust a seller they've never met.
