As a POS (Point‑of‑Sale) agent in Nigeria, sometimes customers dispute transactions. They contact their bank and raise chargebacks. A chargeback means the customer says the transaction was not valid (fraud, wrong amount, no goods or service delivered, etc.), and asks the bank to reverse the charge. As an agent, this can hurt you financially if you lose the dispute.

This guide helps you understand what chargebacks are, why they happen, and more importantly how to resolve them properly so you protect your money and reputation. I explain step‑by‑step what to do. The language is simple, so even someone new in business can follow.

What Is a Chargeback & Why It Matters for POS Agents

• A chargeback is when a cardholder (customer) asks their bank or card issuer to reverse a transaction that was already approved and paid via POS.

• The bank investigates and if they find the customer’s claim valid, they take the money back from the merchant (which includes you, the POS agent) and give it back to the customer.

How Chargebacks Differ from Refunds or Disputes

Why Chargebacks Matter for POS Agents

• Loss of revenue: you may lose the transaction amount plus fees.

• Reputation: repeated chargebacks can reduce trust; might lead bank or POS provider to penalize you or reduce privileges.

• Cashflow risk: must often front the cost of goods or cash before transaction reversal.

• Legal, regulatory risks: false claims by customers raise issues; agent may need to prove services or goods delivered.

Common Reasons Why Chargebacks Happen in Nigeria

To resolve chargebacks, you must understand common causes. Here are many reasons, with Nigeria-specific context when possible.

Reason 1 — Goods or Service Not Delivered

Customer claims they paid but did not get product or service. Maybe merchant promised but failed to deliver or got delayed.

Reason 2 — Wrong Amount Charged or Double Charge

Customer sees more money taken than expected, or transaction accidentally processed twice.

Reason 3 — Fraudulent or Unauthorized Transaction

Customer’s card used without their permission, perhaps stolen card, compromised credentials, or via “card not present” scenario.

Reason 4 — Customer Claims “Item Defective” or “Not As Described”

Perhaps service or product did not meet quality or description expectations.

Reason 5 — Technical or System Errors

POS terminal or bank switch malfunction. For example, system shows success but cardholder not informed; or bank sends reversal incorrectly.

Reason 6 — Customer Mistake / Contesting Legit Transaction

Customer doesn’t recall doing the transaction, or claims it was mistake.

Reason 7 — Dispute Window & Time Lapses

In Nigeria, regulatory or bank policies may have windows for chargebacks. If merchant doesn’t respond in time, they automatically lose.

• Example: Policies allowing cardholders to initiate chargeback within 6 months; merchants sometimes have only 48 hours or less to respond.

Reason 8 — Poor or Missing Evidence from Merchant Side

Receipts not printed, no proof of delivery, no signed confirmation, lack of transaction logs or physical proof.

How the Chargeback Process Works for POS Agents in Nigeria

Here’s a general flow of what happens when a customer raises a chargeback in a POS transaction, and what your role is.

Step 1 — Customer Initiates Chargeback via Issuing Bank

• Customer contacts their bank (the bank that issued their card).

• They give reason (product/service not delivered, fraud, etc.). They submit relevant claims or complaints.

Step 2 — Bank / Card Issuer Notifies the Acquiring Bank / POS Switch

• The issuing bank sends a chargeback notice to the bank or POS provider (acquirer or switch) that processed the transaction.

• The POS provider then notifies you (the agent / merchant) about the dispute.

Step 3 — Agent / Merchant Receives Notification

• You will receive a chargeback claim or dispute notice. It usually contains transaction details: date, amount, last digits of card, reason code (why they claim chargeback).

Step 4 — Gather Evidence & Response

• You must respond with documents proving transaction was valid or service delivered. Examples: merchant receipts, signed customer confirmation, delivery note, CCTV, photos, logs.

• The POS provider or bank may set deadline (e.g. 48 hours) for your response.

Step 5 — Bank / Switch Reviews Evidence

• They evaluate evidence from you vs customer’s claim. They may contact customer for counter‑information.

Step 6 — Decision: Chargeback Accepted or Declined

• If evidence is good and shows you delivered as promised, transaction may be declined (chargeback denied), so you keep the money.

• If evidence is insufficient, or merchant misses deadline, bank accepts chargeback, funds deducted from your account.

Step 7 — Settlement / Reversal

• If chargeback accepted, reversal: amount is taken from merchant/payments due, returned to customer.

• If declined, no reversal; sometimes customer has further appeal window.

Step‑by‑Step for POS Agent: How to Resolve Chargebacks Successfully

Here is what you (the POS agent) should do, step by step, to respond to chargebacks and maximize chances of winning dispute.

Step 1 — Set Up Good Transaction Record Keeping

Before any problem arises, make sure you’re keeping good records:

• Always print or give receipt with details: date, time, amount, last four digits of card, merchant name, POS terminal ID.

• If possible, get customer to sign, or get acknowledgement. For delivery or larger items, maintain delivery note, customer signature, or photo.

• Store electronic logs: transaction logs in POS, summary reports, daily batch reports.

Step 2 — Train on Proper POS Usage

• Make sure you select correct account type (Savings / Current) when customer uses card. Mistakes here can be grounds for chargeback.

• Enter amount carefully; double check before pressing “enter” or “confirm.”

• Use valid terminal; ensure firmware or software updates are applied; ensure terminal displays merchant name or ID.

Step 3 — When Chargeback Notice Arrives, Act Fast

• Read the dispute reason code and transaction details carefully.

• Note deadline given by POS provider or acquiring bank to respond. Missing deadline often means automatic loss.

Step 4 — Gather Supporting Evidence

Depending on reason, collect relevant proofs:

Step 5 — Fill Response / Dispute Form Correctly

• Use the form provided by acquiring bank or POS provider. Include clear evidence, attachments.

• Be concise and factual. State exactly what happened, reference the transaction ID, date, amount.

Step 6 — Submit to the Right Authority & Follow Up

• Send to your acquiring bank / POS provider’s dispute resolution desk. Ensure you keep proof (email, screenshot) of submission.

• Follow up regularly until resolution. If there is a portal or dashboard, check dispute status.

Step 7 — If Decision Favors You, Retain Your Earnings

• If chargeback is declined (customer’s claim rejected), ensure funds are not taken from your account.

• If any reversal mistakenly done, ask for recredit with your bank/POS provider, with dispute evidence.

Step 8 — If Decision Not Favorable, Accept & Learn

• If chargeback is accepted, accept that you may lose the transaction amount. Use experience to improve.

• Identify where process failed: was evidence missing? Did you respond late? Was there error in how the POS terminal was used?

Examples & Scenarios of Chargebacks for POS Agents in Nigeria

Here are realistic examples to illustrate the process in context.

Example 1 — Food Vendor & “Goods Not Received” Claim

• A customer orders food at a small shop using POS. After receiving food, she claims the food was cold and wants refund. Pays ₦5,000.

• She later contacts bank claiming “goods not delivered” or “service not as described.”

• Agent’s evidence: receipt, maybe photo of food being served, customer signature or name, daily batch report.

• Agent responds to bank with evidence. Bank reviews. If evidence good, chargeback is declined. If not, agent loses.

Example 2 — Double Charge by Mistake

• Merchant accidentally swipes card twice for the same purchase. One successful transaction, one duplicate. Total ₦10,000 instead of ₦5,000.

• Customer notices extra charge, raises chargeback.

• Agent’s evidence: POS terminal logs showing duplicate swipe, bank statement, perhaps customer receipt showing only one service.

• Respond quickly. If logs and bank show duplicate, bank may reverse duplicate.

Example 3 — Unauthorized Transaction Claim

• A customer’s card was stolen; fraudster uses it at POS. POS agent unaware (card looked fine, PIN entered).

• Customer reports fraud, raises chargeback.

• Agent’s evidence: signed receipt, card present, maybe CCTV, confirmation of transaction.

• This type of dispute may be tougher; could be lost if cardholder proves non‑possession or bank policy favors them.

Example 4 — Technical Error

• POS terminal had connectivity issue; terminal timed out but merchant gave receipt or system logged success. Customer claims “charged but no service.”

• Agent uses POS / switch logs, transaction record, perhaps error report.

• Respond to dispute; if bank sees system error but proof that transaction did go through or service delivered, agent may win.

Summary Table Before Conclusion

Here is a summary table of chargeback reasons, what to check, what evidence to gather, and key deadlines or policies.

Frequently Asked Questions (FAQs) about Chargebacks for POS Agents

Here are many common questions POS agents or merchants ask, and clear answers.

1. What is a dispute code or chargeback reason code?
   It’s a code from the bank or switch that indicates why the customer is raising chargeback (fraud, not received, duplicate, etc.). Knowing this helps you gather correct evidence.

2. How soon must I respond after I get a chargeback notice?
   Usually very quickly. Many acquiring banks or POS providers require merchant to respond within around 48 hours of receiving the notice. If you miss deadline, you may lose automatically.

3. Can I win a chargeback if I don’t have a printed receipt?
   Possibly, but it is much harder. Receipts are strong evidence. If you don’t have printed receipt but have digital logs, photos, or customer confirmation, you might still succeed.

4. What if the customer shows that they paid, but bank still reversed?
   You need strong proof: signed receipt, POS log, proof goods/service delivered. If you have that, you challenge via your acquiring bank / POS provider.

5. Can I avoid chargebacks by refusing some transactions?
   Yes, particularly high risk ones (large amount, unknown customer, no signature, poor connectivity). But you must balance with business volume.

6. Who pays the cost of chargebacks?
   As POS agent/merchant, you typically bear the cost if you lose the dispute: the transaction amount plus any fees. If you win, customer may bear cost or be refused.

7. Is there any regulation in Nigeria protecting merchants/agents in chargeback cases?
   Yes, CBN and payment switch policies often lay out timelines and rights. But many agents feel policies favour customers or cardholders. POS merchants association has lobbied for change.

8. What if customer’s claim is false or fraudulent?
   You can provide evidence to disprove the claim. Provision of good documentation, signature, or physical delivery proof helps. If banks accept your evidence, chargeback is reversed or declined.

9. Do POS providers or acquiring banks help agents with evidence or support?
   Many do. Some providers give dashboards for transaction logs, summaries; others offer support lines or help with retrieving logs. Ask your provider.

10. How long does it take to resolve chargeback cases?
    It varies. Some resolve in days, other cases take weeks. Depends on provider, evidence, cooperation.

11. If I lose a chargeback case, can I appeal?
    Sometimes yes. Some banks or providers have an appeal or arbitration stage. But quality of evidence and timeliness are crucial.

12. How can I prevent or reduce fraudulent chargeback claims?
    Keep good records, issue receipts, get signatures, use cameras/CCTV, train staff, ensure transparency with customers.

13. Can I insure or get protection against chargebacks?
    A few fintechs may offer some chargeback protection or insurance for merchants in certain programs. But often this is part of premium or enterprise agent agreements.

14. Does chargeback affect my standing with POS provider or acquiring bank?
    Yes. Frequent chargebacks can lower your credibility; provider may reduce your privileges, raise fees, or in worst cases, revoke your POS service.
