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
Keystone Bank is a CBN-licensed commercial bank that lends to individuals and businesses, with personal credit typically built around salary paid into a Keystone account and business credit around account turnover and collateral. We did not verify Keystone's current loan product names, limits or rates on a product page in this review, so check them on Keystone's website, app or at a branch, and compare the naira total with other offers.
Keystone Bank in brief
Keystone Bank is one of Nigeria's commercial banks and is licensed by the CBN, which also supervises its lending. Its ownership history is unusual: it began as a bridge bank created when an earlier bank was rescued, and questions about who owns it come up often. We cover that separately in bridge banks explained and Keystone Bank's ownership. For a borrower, the practical point is simpler: a loan from Keystone is a loan from a licensed bank, and complaints go to the bank first and then the CBN.
The main kinds of Keystone loan
Commercial banks in Nigeria generally offer the same families of credit, and Keystone is no exception. The names and terms change, so confirm them with the bank:
| Type | Who it is for | What it is usually based on |
|---|---|---|
| Salary advance | Employees paid through Keystone | Monthly salary and repayment from next payday |
| Personal or term loan | Salaried staff, including public sector | Salary, employer, debt-to-income, bureau record |
| Digital quick loan | Existing account holders | Account activity seen by the bank |
| Overdraft | Individuals and businesses with steady inflows | Turnover and relationship with the bank |
| Business or SME loan | Registered businesses | Turnover, financial records, collateral |
| Asset finance | Individuals and businesses buying a car or equipment | The asset itself, plus equity contribution |
Who usually qualifies
Individuals
- A Keystone account in your name, with BVN linked and your salary paid into it for salary products.
- Confirmed employment; some products only cover staff of employers the bank has assessed.
- Total monthly repayments that fit within a share of net pay the bank sets.
- No arrears on your credit bureau record.
Businesses
- CAC registration and the business account in the company's name.
- Several months of turnover through the account. See financial statements for a loan application.
- Collateral or a guarantee for larger amounts, with documents that can be perfected.
- Tax records where the bank asks for them.
Reading the cost: flat versus reducing balance
The most important line in any Keystone offer letter is how interest is calculated. A flat rate charges interest on the full amount for the whole term; a reducing-balance rate charges only on what you still owe. Two offers with the same headline rate can cost very different amounts. Here is a worked example with invented terms, not Keystone's pricing, for ₦400,000 over 4 months at 3% a month:
| Month | Flat: interest | Reducing: balance at start | Reducing: interest |
|---|---|---|---|
| 1 | ₦12,000 | ₦400,000 | ₦12,000 |
| 2 | ₦12,000 | ₦300,000 | ₦9,000 |
| 3 | ₦12,000 | ₦200,000 | ₦6,000 |
| 4 | ₦12,000 | ₦100,000 | ₦3,000 |
| Total | ₦48,000 | ₦30,000 |
This assumes ₦100,000 of principal is repaid each month. Same rate, ₦18,000 difference. Add any management fee and insurance to both totals before comparing. Our guide to APR vs flat fee goes further.
Keystone loan vs a loan app
- Keystone lends under a CBN banking licence; most apps are non-bank lenders registered with the FCCPC.
- Bank loans usually run for months with monthly instalments; app loans are often 7 to 30 days.
- A bank recovers from your account; it has no need to read your contacts.
- An app may decide faster on small sums, but compare the naira total, not the speed.
Questions to ask Keystone before you sign
- Is the rate flat or reducing balance, and is it monthly or annual?
- What fees are deducted upfront, and is insurance compulsory?
- What is the late-payment charge and how is it calculated?
- Can I repay early, and is there a charge for it?
- For salary loans: what happens if I change employer during the loan? For steps, see how to get a Keystone Bank loan.
Business borrowers: preparing a stronger application
For SME credit, banks tend to decide on evidence rather than promises. Run your sales through the business account rather than personal accounts, keep invoices and receipts that match the inflows, and file returns on time. A bank that sees six to twelve months of consistent turnover is in a better position to offer a sensible amount than one shown a single large deposit last week.
If collateral is involved, have the title documents checked before you apply. Documents that cannot be registered in the bank's favour slow everything down and can end the application. Ask Keystone which forms of security it accepts for the size of loan you want, and whether a guarantee from a director or a third party is acceptable instead.
Finally, keep copies of everything you submit. If the bank asks for the same document twice or the application stalls, a dated record of what you provided makes follow-up quicker.
