Natillera, cooperative or employee fund: which is which.

All three bring savings and loans together among people, but they are not the same: they differ in who can take part, which rules cover them and who oversees them. This guide compares them in simple terms.

A natillera is an informal agreement among people who know each other; an employee fund is a formal solidarity-economy entity of the workers of a company or group of companies; and a savings and credit cooperative is a formal solidarity-economy entity, open to those who meet its common bond, with member share contributions and democratic governance. The last two are legal entities with rules and oversight; a natillera is not.

When a natillera is enough

It is a small, closed group of people who know and trust each other.
The cycle is short (traditionally January to December) and the money is distributed at the end.
No one outside the group contributes or receives money.
They accept that there is no insurance or oversight: trust and clear records are the protection.

When an employee fund makes sense

Those taking part are workers of the same company or group of companies.
They want permanent savings and loans for the members, with bylaws and an assembly.
They are willing to meet the formal obligations of a solidarity-economy entity.

When a cooperative makes sense

They want to open participation to more people who share a bond (a profession, a community, a guild).
They seek a common estate with member share contributions and democratic governance.
They are willing to accept the formality and oversight that come with offering savings and credit.

The line not to cross

A natillera stops being one when it starts taking money from people who do not belong to the group or from the public at large: taking money from the public is a regulated activity and may require authorization. If your natillera grows, or you want to open it to strangers, it is time to consult a lawyer about setting up a formal entity.

Moving from one to another

Many employee funds and cooperatives started as an informal savings group. The sign that it is time to take the step is usually the same: more people, more money and a need for rules, governance and control that no longer fit in a spoken agreement. Setting up a solidarity-economy entity requires its own procedures and legal and accounting advice.

What each one is run with

NatIA Ahorro is built for natilleras: installments, loans and distribution in exact cents. CooperativIA is designed for cooperatives, funds and associations: contributions, loans with a usury cap, assemblies with quorum and minutes, in your institution’s vocabulary. Neither receives or holds the money, and neither replaces compliance with the rules that apply to the institution.

Questions

Frequently asked questions

Can a natillera lend to people outside the group?

It is better to avoid it. Lending to an outsider is not the same as taking in money from the public, but it increases risk and blurs the nature of a closed group of people who know each other. If it happens often, consult a lawyer.

Which one is safer?

None is free of risk. Formal entities have bylaws, control bodies and state oversight; a natillera depends on trust and on records. Always check an entity’s situation before leaving your money with it.

Do you need to be linked to a company to join a cooperative?

It depends on its bylaws: each cooperative defines its common bond, which can be a company, a guild, a profession or a community.

Is this guide legal advice?

No. It is an educational guide and the rules may change. To set up an entity or resolve legal questions, consult a lawyer.
