What it means
ISO was founded in 1947 and has produced a very large library of standards. The standards themselves are agreements on how something should be done or measured, so that a part made in one country fits a machine built in another and a process run in one company can be understood by another.
The standards are voluntary unless a law or contract says otherwise. Some of its standards are about management systems rather than products.
Well-known examples include the ISO 9001 standard for quality management, the ISO 14001 standard for environmental management and the ISO 27001 standard for information security. Each is a set of requirements that a company can be audited against.
Finance people meet ISO in several ways. The ISO 4217 standard assigns the three-letter currency codes, such as USD, that appear on invoices and in payment systems, and other ISO standards cover items like country codes and bank account number formats.
Without those common formats, automated payments between banks would fail far more often. Certification is common in business.
A company can ask an independent auditor to check that it follows a standard, and a certificate can be a requirement for tenders, a boost to customer trust or a sign of good internal control. Procurement teams often treat a valid certificate as a quick filter when screening new suppliers.
Getting and keeping certification costs money, because of consultant fees, staff time, audits and regular surveillance visits. The benefits are fewer defects, less rework and, in some industries, access to contracts that would otherwise be closed.
A business should compare the full cost of certification with the revenue it expects to win or protect. The nuance is that ISO does not certify companies itself.
Independent certification bodies do that, and holding a certificate shows that a system meets a standard, not that every product is perfect.
In practice
Real-world examples.
Example
A parts supplier wants to sell to a large automotive manufacturer. The manufacturer requires suppliers to hold a quality management certificate under ISO 9001. The supplier budgets for consultants and an audit, and wins a three-year supply contract once the certificate is issued. The finance team spreads the certification cost over the contract term.
Example
A software-as-a-service company stores customer financial data. It pursues certification under ISO 27001 to show clients that it manages information security properly. The finance director treats the cost as a sales expense, because enterprise buyers ask for the certificate. Renewal audits are scheduled in the annual budget.
Example
A treasury team builds a payment system for several countries. It uses ISO 4217 currency codes and ISO country codes in its data fields, so every payment instruction is read the same way by each system. This reduces errors when payments pass between banks and software.
Case study
Seen in the real world.
This is an illustrative story about a fictional contract manufacturer, Evergreen Precision Parts, which kept losing tender bids to rivals with quality certificates. Its products were good, but buyers could not verify its processes, and its scrap rate was above 6%.
The owner invested $40,000 in preparing for certification under ISO 9001, including consultant fees, training and the first audit, and agreed to repeat audits each year at a lower cost. The process forced the team to document procedures, track defects and fix recurring problems.
Within eighteen months the scrap rate fell below 3%, and the company won two contracts that had required certification. The illustrative figures show that the benefit came from both better operations and better access to customers, although the extra annual cost of surveillance audits had to be budgeted. The owner estimated that reduced scrap alone repaid about half of the initial spend in the first year.
Watch out
Common mistakes.
- Saying a company is ISO certified without naming the standard. There are many standards, so the number matters.
- Treating ISO as a regulator. It publishes voluntary standards, although governments or contracts may make them mandatory.
- Believing certification guarantees product quality. It shows that a management system meets the standard, not that no errors can occur, so buyers should still inspect samples and monitor delivery performance.
Questions
People also ask.
Is ISO a government agency?
No. It is an independent, non-governmental body whose members are national standards bodies.
Do ISO standards cost money?
Many are sold as documents, and certification involves audit fees, so the total cost depends on the standard, the size of the company and the number of sites that need to be audited.
Why do currency codes follow an ISO standard?
A common code such as USD prevents confusion between currencies with similar names and lets software around the world exchange payment data accurately.
