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
Winning IT support work with a Nigerian bank means passing vendor onboarding first: company documents, tax details, security and data protection questionnaires, references and often a local presence or partner. Payment usually follows purchase orders and invoices on 30 to 90 day terms, and the bank will deduct Nigerian withholding tax (10% on technical and management fees paid to a non-resident, a final tax for non-resident companies) and may raise VAT under the Nigeria Tax Act 2025.
Why banks buy from diaspora specialists
Nigerian banks run core banking systems, card switches, mobile apps and data platforms that need specialist support, and many of the people who know those systems work in the US. A diaspora engineer or small US firm can offer after-hours cover across time zones, niche product expertise, or project work such as migrations and security reviews. The opportunity is real, but banks are regulated institutions with formal procurement, and the process is slower than selling to an SME.
Getting in the door
Most contracts start with an introduction: a former colleague now in the bank's IT team, a systems integrator that needs a specialist, or a product vendor whose Nigerian clients need local-hours support. Banks rarely buy from unsolicited emails alone. Partnering with an established Nigerian integrator can get you through procurement faster, with you as a subcontractor; the trade-off is a share of the fee and less control over the client. If you go direct, expect a proof-of-concept or a small paid assessment before a long support contract, and price it as a real engagement rather than free work.
Vendor onboarding: what you will be asked for
| Area | Typical requests |
|---|---|
| Company | Certificate of incorporation, ownership details, directors, registered address; Nigerian CAC documents if you have a local entity |
| Tax | US tax identification, Nigerian TIN if registered, tax residence evidence |
| Financial | Recent financial statements, bank reference, insurance certificates |
| Experience | Client references, CVs of named engineers, case studies |
| Security | Information security questionnaire, policies, certifications if held, incident response process, background checks on staff |
| Data protection | How you process personal data of Nigerian customers, where data is stored, sub-processors |
| Legal | Signed master services agreement, NDA, code of conduct, anti-bribery declarations |
Nigerian banks use vendor registration forms that follow a similar pattern; a Nigerian vendor registration form shows the fields you will meet. Prepare a vendor pack once and reuse it.
Data protection
Support work often means remote access to systems holding customer data. The Nigeria Data Protection Act 2023 applies to processing personal data of people in Nigeria, and a Mondaq summary notes that the controller bears the burden of proving a lawful basis such as consent. The bank will want contract terms that make you a processor acting on its instructions, with security, breach notification and audit rights. Do not copy production data to your own systems unless the contract allows it. See handling Nigerian client data.
Payment terms
- Purchase orders: no PO, no payment. Do not start work on an email promise.
- Invoice cycles: banks often batch vendor payments; 30 to 90 days after an approved invoice is common. Invoicing corporate clients in Nigeria explains the cycle.
- Currency: naira contracts are simpler for the bank; dollar contracts need the bank to source and approve foreign currency, which can add time.
- Milestones and retainers: monthly support retainers in arrears, project fees on milestones with acceptance criteria.
- SLAs and penalties: service credits for missed response times are normal; cap them, for example at a share of the monthly fee.
Tax deducted by the bank
Under the Deduction of Tax at Source (Withholding) Regulations 2024, PwC's summary (reviewed 29 May 2026) lists 10% for commission, consultancy, technical, management and professional fees paid to non-residents, and says that for non-resident companies this WHT on technical, consulting, professional and management fees is a final tax. The regulations also say a deduction is doubled where the recipient has no TIN, so ask the bank how it treats foreign vendors without a Nigerian TIN.
A Mondaq review of the Nigeria Tax Act 2025 says services consumed in Nigeria are taxable for VAT whether rendered inside or outside Nigeria, and that the Nigerian customer may withhold and remit the VAT. Banks' tax teams apply these rules carefully, so agree the VAT treatment before you price.
| Worked example: monthly support retainer (illustrative) | US dollars |
|---|---|
| Invoice | 8,000 |
| WHT at 10% (non-resident technical fee) | 800 |
| Paid to your US company | 7,200 |
| Annual, 12 months | 86,400 received; 9,600 withheld |
The US has no tax treaty with Nigeria, so no reduced rate applies. Whether the Nigerian tax supports a US foreign tax credit depends on your entity and the credit limitation, which turns on how much of your income is foreign-source; ask your preparer before you price.
What to check first
- A complete vendor pack: company, tax, financial, security, data protection.
- Whether the bank needs a Nigerian entity or partner for this contract.
- Fee stated gross or net of WHT and VAT.
- PO in hand before work starts; invoice format matching the bank's requirements.
- SLA penalties capped and acceptance criteria written down.
Where Pryme fits
A Pryme Business Account opened from the US gives your company naira and dollar account details for bank-issued payments. The Compliance agent can keep your vendor pack and renewal dates current, and the Finance agent can reconcile payments against invoices and WHT receipts for you to approve; see Compliance agent.
