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 private esusu or ajo group, where members you know each pay in a fixed amount and take turns receiving the pot, is a common informal arrangement, and we found no federal rule that bans it as such. The legal lines appear when it stops being a circle of members: an organiser who runs it as a business moving money for others can need a state money transmitter licence, and anyone promising returns on pooled money may be offering an investment. Either way, the pot is not a bank deposit, so the protection is your rules and records.
Rotating savings groups travelled with Nigerians to Houston, Atlanta, Maryland and New Jersey. Ten friends pay $500 each month; each month one member collects $5,000. The person who collects early gets an interest-free advance; the person who collects last has saved with discipline. It works because members know and trust each other. It fails when that trust is misplaced, or when the group quietly turns into something else.
How a typical group runs
- A fixed number of members and a fixed contribution, for example 10 members at $500 a month.
- A rota setting who collects in which month, often agreed by ballot or need.
- A coordinator (often called the iya ajo or collector) who receives and pays out.
- The cycle ends when every member has collected once.
Nobody earns interest, and nobody should: each member gets back exactly what they paid in, earlier or later.
Where the legal lines are
Money transmission
Federal law makes it a crime to run an unlicensed money transmitting business. Under 18 U.S.C. 1960, a business is unlicensed if it operates without a state licence where state law punishes that, fails to register under federal law, or moves money known to be criminally derived. New York's Department of Financial Services, for example, says a licence under Banking Law section 641 is needed to receive money for transmission. A circle of friends pooling their own money is a long way from this, but a coordinator who runs many groups for strangers, charges fees, or sends members' pay-outs abroad as a service is moving towards it. If that describes your group, take legal advice in your state.
Investment promises
A group that promises members more than they put in, for example "join for $500 a month and collect $7,000", is no longer a savings rotation. The money must come from somewhere, and if it comes from new members it is the pattern Investor.gov describes as a Ponzi scheme: "an investment fraud that pays existing investors with funds collected from new investors." Investor.gov's page on scams targeting groups warns that fraudsters are, or pose as, members of the group and often recruit respected leaders first.
No deposit protection
Money held by a coordinator is not a bank deposit. If the coordinator disappears, spends the pot or dies mid-cycle, members can only pursue them or their estate.
The real risks
| Risk | What it looks like | Safeguard |
|---|---|---|
| Early collector stops paying | Member collects in month 2, then leaves | Late-rota members first, or a written promise to keep paying |
| Coordinator misuse | Pot held in a personal account, slow pay-outs | Pay directly to the collecting member, not via the coordinator |
| Cash disputes | "I paid you in cash at church" | Bank transfers with a reference only |
| Group grows too fast | New members recruited to fund promised pay-outs | Fixed membership per cycle; no promised extras |
| Death or relocation mid-cycle | Member moves back to Nigeria | Written rule on what happens to their position |
Written rules that protect everyone
- Members' full names, phone numbers and the amount and due date of each contribution.
- The rota, signed or acknowledged in writing by each member.
- How contributions are paid: directly to the collecting member's bank account, with a reference such as "Ajo Oct 2026".
- What happens if someone pays late or stops paying after collecting.
- What happens on death, illness or moving abroad.
- A shared ledger, updated each month, that every member can see.
Example: the early collector problem
Example only. Ten members, $500 a month. Member A collects $5,000 in month 1, then stops paying from month 4. A has paid $1,500 and received $5,000. The remaining nine members are short $3,500 over the rest of the cycle, and the last collector receives $3,500 less unless the group covers it. A written acknowledgement from A of the $3,500 debt gives the group something to enforce.
Tax and records
We found no IRS page specific to rotating savings groups. Collecting your own contributions back is not the same as earning income, but fees, bonuses or anything above what you paid in are different, and large cash movements raise questions at banks. Paying by bank transfer and keeping the ledger lets you show where every dollar came from. Ask a tax preparer if your group pays anything beyond contributions.
The Nigeria library compares ajo and esusu with a savings app, and our US guide to Ponzi schemes aimed at Nigerians in the US covers what happens when a group turns into a scheme.
Where Pryme fits
If your esusu pot is meant for spending in Nigeria, such as school fees or building materials, a Pryme Personal Account lets you hold it in dollars and convert with Swap when you choose, and pay Nigerian accounts with Send. The app shows the rate and the fee before you approve. Saving in naira for family at home can also go into a Savings Box, described at Savings Boxes.
Questions people ask
Is esusu legal in the United States?
A private group of members pooling and rotating their own contributions is a common informal arrangement, and we found no federal rule banning it as such. Running it as a money-moving business, or promising returns, can raise licensing or securities issues.
Is my money safe in an ajo group?
It is not a bank deposit, so there is no deposit insurance. Your protection is written rules, bank-transfer payments, a shared ledger and trustworthy members.
Do I pay tax on my ajo payout in the US?
We found no IRS guidance specific to rotating savings. Getting back what you paid in differs from earning income, but ask a preparer if the group pays fees, bonuses or anything extra.
What if someone collects early and stops paying?
Get a written acknowledgement of what they owe. Agreeing in advance that early collectors are members with a payment record reduces the risk.
