A CABYS code identifies the class of good or service shown on a Costa Rican electronic document. The Central Bank and Ministry of Finance developed the catalog, which organizes thousands of products into a hierarchy ending in 13-digit codes. A business does not need to memorize the structure. It needs a repeatable way to find the code that best describes what it actually sells and to retain the reasoning behind that choice.
One common mistake is searching for the shortest word in an internal item name. A catalog entry called "monthly service" could match many unrelated categories. Another mistake is choosing the first result that shows the expected IVA rate. The rate may prompt a review, but the code should describe the product or service rather than the tax outcome the company hopes to apply.
CABYS, SKU and economic activity are different fields
A SKU is an internal key created by the business to distinguish sizes, presentations or inventory families. An economic activity describes the taxpayer's registered lines of business. CABYS classifies each invoiced good or service. The three fields can be related, but they perform different jobs. A café may have one registered economic activity, hundreds of SKUs and several CABYS codes across its menu and merchandise.
- SKU: operates the company's own product, inventory and price catalog.
- Economic activity: identifies the activities registered by the taxpayer.
- CABYS: classifies the good or service on an electronic document line.
- Commercial description: tells the customer what was purchased and can be more specific than the official catalog name.
A five-step search method
Begin with a literal description rather than a marketing name. Instead of "growth plan", write what the customer receives: software hosting, technical support, consulting, maintenance or another service. For a physical product, include its material, use, presentation and any characteristic that could change classification. That working sentence provides better terms for the BCCR catalog search.
- Define the good or service in one concrete sentence.
- Search for the main noun, then add its use, material or intended user.
- Read the full hierarchy of a result, not only the final description.
- Compare two or three nearby candidates and discard those in the wrong family.
- Record the selected code, review date and person who validated it.
The hierarchy exposes misleading matches. Two final descriptions may sound similar while belonging to entirely different general categories. If a company sells equipment installation, for example, it may need to separate the equipment from labor and review whether they belong on distinct lines. Do not force one code onto a bundle simply because the invoicing screen allows a default.
What to do when the answer is unclear
Keep the candidate codes and consult the person responsible for tax or accounting. The useful question is not "which one shows 13 percent?" but "which one describes this transaction, and what rule supports its treatment?". For a new product or an item with a special rate, a review before the first sale prevents the same mistake from being copied into dozens of invoices.
The catalog changes over time. The 2025 update replaced earlier codes, and Hacienda stated that only the new version would be accepted after June 1 of that year. The lesson is straightforward: CABYS setup is not permanent. Businesses need to monitor official notices and have a way to locate the items affected by a revision.
Maintaining CABYS inside the accounting system
Tario keeps products and services in a catalog with prices, units, suppliers and tax data. Associating the CABYS code there avoids searching again for every invoice. A person should still review changes before applying them across many items. The goal is to reuse a sound decision, not to repeat an uncertain one automatically.
A quarterly catalog review is usually easier than an emergency cleanup. Start with recently sold items, lines carrying special rates and products created more than once. Improve ambiguous internal names while you are there. A clear catalog supports invoicing and also makes inventory, reporting and conversations with the accountant easier.
