AI agents for business finance: what they can and can't do
What AI agents can do in bookkeeping, close, collections and compliance today, where a person must stay in charge, and how to judge a product.
The short answer
An intrabank transfer moves money between two accounts at the same bank; an interbank transfer goes to a different bank, usually through NIBSS Instant Payments. Intrabank transfers are often free (UBA and Zenith publish them as free on digital channels), while interbank transfers carry a fee: the CBN's 2020 Guide to Charges sets ₦10 below ₦5,000, ₦25 from ₦5,001 to ₦50,000 and ₦50 above. The ₦50 stamp duty on ₦10,000 or more applies to both, except between your own accounts at the same bank.
Every Nigerian transfer is either within one bank or between two. The difference used to mean hours versus days. Today both are usually instant, but the cost and the stamp duty treatment still differ, and the gap is worth knowing if you make many payments.
How each one moves
- Intrabank (same bank)
- The bank debits one customer and credits another on its own books. No outside switch is needed, so it is typically immediate.
- Interbank (different banks)
- The sending bank passes the payment through a national switch, almost always NIP for app and USSD transfers. NIP runs 24/7 and is usually completed in seconds, but it depends on both banks' systems being up.
Because interbank transfers involve two banks and a switch, they are the ones more likely to show as pending or fail with money debited. See transfer pending but not credited for what to do.
Fees: the CBN bands and what banks publish
The CBN Guide to Charges (effective 1 January 2020) sets the ceiling for electronic transfers to other banks. Banks add 7.5% VAT on the fee.
| Amount sent to another bank | CBN 2020 maximum fee | With 7.5% VAT |
|---|---|---|
| Up to ₦5,000 | ₦10 | ₦10.75 |
| ₦5,001 to ₦50,000 | ₦25 | ₦26.88 |
| Above ₦50,000 | ₦50 | ₦53.75 |
As at September 2026, UBA's published Service Charges and Rates follows these bands for app and internet banking transfers to other banks and lists UBA-to-UBA transfers on the app, Leo chat and internet banking as free. Zenith Bank's FAQ says Zenith-to-Zenith transfers are free. Banks can charge less than the ceiling, and some fintechs give a number of free interbank transfers a month, so check your own app.
Stamp duty on both
From 1 January 2026, the ₦50 stamp duty on electronic transfers of ₦10,000 or more is paid by the sender, whether the recipient is at the same bank or another. The published exemption for transfers between your own accounts covers only accounts at the same institution, and Moniepoint, for instance, limits it to its own accounts sharing one BVN. Full detail: EMTL and the ₦50 stamp duty.
Worked example: three payments compared
Example only, using the CBN 2020 bands with VAT and assuming the bank charges the full ceiling and nothing for same-bank transfers.
| Payment | Intrabank cost | Interbank cost |
|---|---|---|
| ₦4,000 to a friend | ₦0 | ₦10.75 |
| ₦30,000 to a landlord's agent | ₦50 stamp duty | ₦26.88 fee + ₦50 stamp duty = ₦76.88 |
| ₦30,000 to your own account | ₦0 (own-account exemption) | ₦26.88 fee + ₦50 stamp duty = ₦76.88 |
| ₦200,000 to a supplier | ₦50 stamp duty | ₦53.75 fee + ₦50 stamp duty = ₦103.75 |
Over a month of twenty ₦30,000 supplier payments, that is ₦1,000 in stamp duty either way, plus ₦537.60 in fees if they all go to other banks (20 × ₦26.88). Whether it is worth asking regular counterparties to bank where you bank is a judgement for you; for most people the convenience of paying anyone instantly outweighs the fee.
Speed: when the difference shows
- Normal days: both are usually instant.
- Bank system outages: intrabank may still work when the switch or the other bank is down.
- Large payments: above daily app limits, an interbank payment may need a different channel or rail; see interbank cut-off times.
- Reversals: a failed intrabank transfer is fixed by one bank; a failed interbank one needs both banks and the session ID.
Which to use for business payments
For a business, the choice is rarely about the fee alone. Intrabank payments to suppliers at your own bank settle on one ledger, which can make reconciliation simpler, and reversals involve only one bank. Interbank payments reach anyone, and with NIP they are normally as fast. If many of your customers pay you from one bank, a collection account there can reduce failed or delayed inflows, but most businesses accept transfers from every bank. Whatever you choose, keep the session ID or reference for each payment, as it is the key piece of evidence if a transfer goes missing.
Name enquiry protects both
Before you confirm, the app shows the recipient's name. For interbank transfers this comes from a name enquiry to the other bank. Always check it; a correct account number at the wrong bank can belong to someone else, because account numbers are unique only within each institution (see what the NUBAN means).
Where Pryme fits
When you send money from Pryme, the confirmation screen shows the recipient's name and the charges before you approve.
Questions people ask
Is transfer to the same bank free in Nigeria?
Often, yes. UBA and Zenith publish same-bank digital transfers as free. Stamp duty of ₦50 can still apply on ₦10,000 or more to another person.
How much is transfer charges to other banks?
Under the CBN's 2020 guide, the maximum is ₦10 up to ₦5,000, ₦25 from ₦5,001 to ₦50,000 and ₦50 above, plus 7.5% VAT.
Which is faster, intrabank or interbank transfer?
Both are usually instant. Intrabank transfers depend only on one bank, so they are less likely to be held up.
Do I pay stamp duty sending money to my own account in another bank?
The published exemption covers your own accounts at the same institution only, so a transfer of ₦10,000 or more to your account at another bank attracts it.
