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
A small digital marketing agency earns most reliably from monthly retainers: a fixed fee for an agreed set of services such as social media management, paid adverts and reporting, with clients' ad spend billed separately. In our labelled example, four retainer clients bring in ₦1,000,000 a month and leave about ₦460,000 after freelancers, tools and running costs. Start with one or two services you can deliver well, and staff with freelancers before you hire.
Choose your service lines
Small agencies fail more often from doing too much than too little. Pick services that fit together and that clients in one sector need.
| Service | What the client gets | Skills needed |
|---|---|---|
| Social media management | Content calendar, posts, community replies | Writing, design, scheduling |
| Paid adverts | Campaign set-up, targeting, optimisation on Meta, Google or TikTok | Ad platforms, analytics |
| Search and website | SEO, landing pages, Google Business Profile | Web, content, analytics |
| Email and WhatsApp marketing | Campaigns to existing customers | Copywriting, list management, consent rules |
| Influencer campaigns | Creator selection, briefs, tracking | Negotiation, contracts |
Sector focus helps you win work. An agency that only serves restaurants, schools or real estate firms can show relevant results and reuse what it learns. For customer messaging, follow consent rules; see WhatsApp promos and the NDPA.
Retainers, projects and ad spend
- Retainer
- A monthly fee for a defined set of work: for example, 12 posts, two ad campaigns and a monthly report. The scope must be written down, or the retainer grows while the fee stays the same.
- Project
- A one-off job such as a website, a launch campaign or a brand refresh, priced as a fixed fee with a deposit.
- Ad spend
- The money paid to Meta, Google or TikTok to run adverts. Keep it separate from your fee: ideally the client pays the platform directly from their own ad account, or you invoice it separately at cost.
- Minimum term
- Many agencies ask for a three-month minimum, because results from ads and content take time to judge.
Worked example: a small agency's month (example figures)
Example only. These are illustrative figures, not market rates. Four clients each pay a ₦250,000 retainer for social media management and one paid campaign a month.
| Line | Monthly (example) |
|---|---|
| Retainer income (4 × ₦250,000) | ₦1,000,000 |
| Freelance designer | ₦200,000 |
| Freelance ads specialist | ₦220,000 |
| Scheduling, design and analytics tools | ₦60,000 |
| Data, power and workspace | ₦60,000 |
| Total costs | ₦540,000 |
| Left for the owner | ₦460,000 |
The owner in this example handles sales, strategy, client calls and copywriting. Lose one client and income falls by a quarter while most costs stay, which is why agencies chase a broad client base and minimum terms. Raising each retainer by ₦50,000 adds ₦200,000 a month with no extra freelancer cost if the scope does not change.
Winning the first clients
The first three clients usually come from people who already know your work. After that, a sector focus and visible results do the selling.
- Run one campaign well for a business you know, at a reduced fee in exchange for permission to publish the results.
- Write a one-page case study: the problem, what you did, and the numbers before and after.
- Approach ten businesses in the same sector with that case study and a specific idea for each.
- Offer a short paid audit of their social pages or ads as a first step, with the fee credited against a retainer if they sign.
- Ask every happy client for a referral within the first three months.
Reports that keep clients
Clients cancel retainers when they cannot see what they are paying for. A good monthly report fits on one or two pages and links your work to the client's own numbers: enquiries, bookings, sales or footfall, not only likes and reach. Show what was spent on adverts, what it produced, what you will change next month and why. If a campaign did badly, say so and explain the fix; clients trust agencies that report bad months clearly.
Staffing: freelancers first
- Start with trusted freelancers paid per client or per task, with written agreements on deliverables, deadlines and confidentiality.
- Give each client one named contact on your side, even if several people do the work.
- Hire your first full-time staff member when one role is busy every week across several clients.
- When you employ staff, payroll, PAYE and pension obligations apply; see PAYE tax bands for 2026.
Influencer work and creator programmes
Clients increasingly ask agencies to run creator campaigns. Some retailers also run their own programmes that pay creators directly: Jumia's KOL programme, for example, has micro-influencer (at least 5,000 followers), mega-influencer and affiliate tracks and pays monthly. Know how those programmes work so you can advise clients on whether to brief creators through you or let creators join a retailer's scheme.
Getting paid and staying organised
- Send a proposal with scope, fee, ad spend arrangement and minimum term; get it signed.
- Invoice retainers in advance, at the start of each month.
- Pause work when an invoice is overdue by an agreed number of days.
- Send a short monthly report linking work to the client's numbers.
- Register a business name or company with the CAC; the May 2025 fee schedule put business name registration at ₦20,000. Larger clients may also deduct withholding tax; see withholding tax on invoices.
Where Pryme fits
A Pryme Business Account includes invoicing for retainers, payroll once you hire, and Finance and Chief of Staff agents that prepare work such as payment runs, with a person approving anything above a set ceiling.
Questions people ask
How much do digital marketing agencies charge in Nigeria?
There is no published standard. Agencies set retainers by scope: number of posts, campaigns and reports. Our labelled example used ₦250,000 a month per client; your price should come from the hours the scope takes.
How do I start a digital marketing agency with no money?
Start with one service you can deliver yourself, find two or three clients through referrals or a sector you know, and use freelancers per job instead of hiring.
Should ad spend be included in my agency fee?
Keep them separate. Ideally the client pays the ad platform directly from their own account, or you invoice ad spend at cost, so your fee is clear.
What services should a small digital marketing agency offer?
Pick a few that fit together, such as social media management and paid adverts, and focus on one sector so you can show relevant results.
