Every Nigerian has either been part of an ajo, contributed to an esusu, or knows someone whose thrift group collapsed with their money still inside it. The model itself — a group of people contributing a fixed amount regularly, with each member taking turns to receive the full pooled amount — is one of the oldest and most effective informal savings tools in Nigeria. It’s also one of the easiest to get wrong, and when it goes wrong, it tends to go wrong with other people’s money, which makes it personal in a way a failed bank product never is.
This guide covers how to structure a thrift group properly — whether you’re starting one among colleagues, market traders, or a friend group — and where digital alternatives fit in for people who want the discipline of ajo without the trust risk of handling cash.
How Ajo/Esusu Actually Works (And Why It’s Effective)
The basic model: a group of people (commonly 5-30 members) agree to contribute a fixed amount on a fixed schedule — daily, weekly, or monthly. Each cycle, one member receives the full pooled amount (everyone’s contribution for that cycle combined). The order of who receives when is agreed in advance, and the cycle continues until every member has received their turn once.
Why it works psychologically: unlike personal savings (which can be skipped, delayed, or raided when tempting expenses arise), thrift contributions are social commitments. Missing a contribution doesn’t just affect you — it affects whoever is scheduled to receive that cycle’s payout, and the social accountability of a group is often a stronger motivator than personal willpower alone.
Example with 10 members contributing ₦5,000 weekly:
- Total pool per cycle: ₦50,000
- Each member receives ₦50,000 once during a 10-week cycle
- A member who receives in week 1 gets ₦50,000 immediately after contributing only ₦5,000 — effectively an interest-free advance
- A member who receives in week 10 has contributed ₦50,000 across the cycle and receives it back as a lump sum — effectively forced savings
This dynamic — early receivers get an advance, late receivers get forced savings — is part of why the order of receiving matters and is often a point of negotiation when groups form.
The Rules That Prevent Most Disputes
Most ajo collapses or disputes trace back to a small number of rules that were never agreed clearly at the start. Setting these explicitly, in writing, before the first contribution, prevents the majority of problems.
1. Contribution amount and schedule — fixed and non-negotiable. Once a group starts, changing the contribution amount mid-cycle creates confusion about who owes what. If circumstances genuinely require a change, this should only happen at the start of a new cycle, agreed by all members.
2. The collection order — agreed and documented before the cycle starts. Whether by seniority, by need (members with urgent needs go first), by random draw, or by request — the order should be fixed and written down, not negotiated on the fly each cycle.
3. What happens if a member misses a contribution. This is the single most common source of disputes. Clear rules should specify:
- A grace period (e.g., contributions due by end of week, with a 2-day grace period)
- A penalty for late contributions (small late fees are common and help enforce discipline)
- What happens if a member misses entirely after already receiving their payout — this is the highest-risk scenario and should have a clear resolution plan (e.g., the member is removed from future cycles, or a guarantor covers the shortfall)
4. Who holds the money, and how. This is the question that determines whether your thrift group is low-risk or high-risk.
Who Holds the Money: The Make-or-Break Decision
Cash-based, single collector model (traditional, highest risk):
One trusted member (often called the “ajo collector” or treasurer) physically collects contributions and distributes payouts. This model has worked for generations in Nigeria, but it concentrates significant risk in one person — if that person becomes unable to fulfil the role (illness, relocation, dishonesty, or simply mismanagement of a large sum of cash), the entire group’s money is at risk.
Rotating collector model:
The role of collector rotates among members, sometimes aligned with whose turn it is to receive (the person before you collects and hands over to you). This distributes trust but doesn’t eliminate the core risk — it just means risk is distributed across more people over time rather than concentrated in one.
Bank account model (lower risk, more transparent):
The group opens a dedicated account (sometimes a joint account requiring multiple signatories, sometimes a single account managed transparently with all members having visibility into transactions via shared statements or screenshots). Contributions are transferred directly rather than handed over as cash, creating a digital record that reduces disputes about who paid what and when.
Digital thrift platforms (lowest operational risk, newer model):
Apps and fintech platforms now offer structured thrift/ajo features — automated contribution collection, scheduled payouts, and digital records — removing the need for a human collector entirely. This significantly reduces the “collector absconds with funds” risk that has ended many traditional ajo groups, though it introduces a different consideration: trusting the platform itself.
Comparison: Traditional vs Digital Thrift
| Factor | Cash/Traditional Ajo | Digital Thrift Platform |
|---|---|---|
| Risk of collector absconding | High | Eliminated (no human collector) |
| Record-keeping | Often informal, dispute-prone | Automated, transparent |
| Flexibility (informal arrangements, special cases) | High — group can adjust rules easily | Lower — platform rules apply |
| Trust required | Trust in specific individuals | Trust in the platform’s reliability |
| Setup effort | Low (verbal agreement, sometimes a notebook) | Requires app setup, sometimes verification |
| Suitable for | Close-knit groups with established trust (market associations, long-term colleagues) | Groups without strong existing trust, or individuals wanting the discipline without group dependency |
Neither model is universally “better” — a market women’s association that has run the same ajo for 15 years with the same trusted collector has a system that works because of established relationships built over years. A newly formed group of coworkers who don’t know each other well may find a digital platform reduces the trust burden significantly.

Setting Up Your First Thrift Group: Step by Step
1. Determine the right group size. Smaller groups (5-10 members) are easier to manage and have less risk concentration, but each cycle takes longer to complete (more turns before everyone has received). Larger groups complete cycles faster per member but require more trust and coordination.
2. Agree on contribution amount based on the least financially flexible member, not the most. A contribution amount that’s comfortable for the highest earner but a stretch for the lowest earner sets up that member for missed contributions and disputes. The amount should be sustainable for everyone, even if it means the payout amounts are more modest.
3. Decide the cycle length and frequency. Daily contributions (common among market traders) work well for those with daily cash flow. Weekly or monthly suits salary earners better, aligning with when income actually arrives.
4. Document everything — even informally. A shared WhatsApp group where contributions are confirmed with screenshots, or a shared spreadsheet, creates a record that prevents “I already paid” disputes weeks later when memories become unreliable.
5. Plan for the “last person” problem. The member receiving last in the cycle has effectively loaned the group money interest-free for the longest period. Some groups address this by giving the last position a small bonus (an extra contribution from everyone in the final cycle) or by rotating who gets the “good” early positions across multiple cycles so the same person isn’t always last.
Red Flags: When to Walk Away From a Thrift Group
- The collector is unwilling to share records or becomes defensive when asked for an update — transparency should be the norm, not a special request
- The group has no plan for what happens if someone defaults after receiving their payout — this scenario will eventually happen in any sufficiently long-running group, and a group without a plan for it is a group where you could be the one left covering the gap
- Contribution amounts keep “temporarily” changing — this is often an early sign of cash flow problems within the group that aren’t being addressed directly
- You’re being pressured to join with an unusually high contribution amount relative to your income, especially from someone who benefits from your participation (a collector earning a cut, for instance) — evaluate whether the amount fits your budget independent of social pressure

Aisha’s Office Ajo
Aisha works in an HR department in Kano with 12 colleagues who decided to start a monthly thrift in early 2025, contributing ₦10,000 each — a ₦120,000 payout per cycle. Initially, they used a simple verbal agreement with one colleague as collector.
By the third cycle, a dispute arose: one member claimed she’d paid but the collector’s records didn’t show it, and neither could prove their version with certainty. The group nearly dissolved over the disagreement.
They restructured: contributions now go directly via bank transfer to a dedicated account, with screenshots shared in a group chat as confirmation, and a shared spreadsheet tracking who has paid and who has received each cycle. The collector role rotates every three cycles.
“The money issue was never really about the money,” Aisha said. “It was about nobody being able to prove anything. Once we had records, the disputes just stopped.”
Frequently Asked Questions
Q: Is thrift/ajo legal in Nigeria?
A: Yes, informal thrift arrangements between individuals are a longstanding and legal practice in Nigeria. They are not regulated financial products in the way bank savings accounts are, which is precisely why structuring them carefully (clear rules, transparent record-keeping) matters — there’s no regulatory body to appeal to if something goes wrong informally.
Q: What’s a reasonable group size for a first-time thrift group?
A: Groups of 6-10 members are often a manageable starting point — large enough that the payout amount is meaningful, small enough that trust and coordination remain manageable, and short enough that a full cycle completes within a reasonable timeframe (a 10-member monthly group completes in 10 months).
Q: Should I join a thrift group with strangers, or only with people I know well?
A: For cash-based or single-collector models, strong existing trust (colleagues, family, established community groups) significantly reduces risk. For groups without strong existing trust between members, a bank-account-based or digital platform model, with full transparency on records, is a safer structure than a traditional cash-collector model.
Q: What happens if I need to leave a thrift group before my cycle is complete?
A: This should be addressed in your group’s rules from the start. Generally, if you leave after receiving your payout but before completing your remaining contributions, you owe the group the outstanding amount — this is the scenario most likely to cause disputes, which is why some groups require a guarantor or require members to complete at least one full contribution cycle before becoming eligible to receive a payout.
The Bottom Line
Ajo and esusu have survived for generations in Nigeria because the underlying idea — social accountability as a savings mechanism — genuinely works better than willpower alone for many people. The groups that fail aren’t failing because the concept is flawed; they’re failing because of unclear rules, undocumented contributions, and too much trust concentrated in one person without any backup plan.
Whether you go traditional (cash, trusted collector, established community) or digital (apps with structured thrift features), the principles are the same: clear rules agreed upfront, transparent records, and a plan for what happens when — not if — something goes wrong with at least one member’s contribution along the way.
