Why writing quetzales correctly matters
In Guatemala, a badly written amount in words can block a check, trigger a SAT observation or void a contract clause. On banking documents, the amount in words prevails over the figure.
Three areas concentrate the risk:
- Bank checks: figure and words must match. If they disagree the words prevail, which is why the amount is closed with "con XX/100".
- SAT invoices (FEL): the Factura Electrónica en Línea is the current regime; printed PDFs include the amount in words.
- Contracts & legal documents: the amount in words gives certainty to the economic clause. A gender-agreement error can be challenged.
This converter automates the three formats, applies RAE rules and uses the Guatemalan number format (comma thousands, period decimal) — all in a single click.
The Q1,234.56 format — comma thousands, period decimal
Guatemala uses the US format. Confusing it with the European one is one of the most common errors.
Comma thousands, period decimal.
Period thousands, comma decimal.
In practice: our converter detects the separator automatically but shows the figure in Guatemalan format. This avoids writing "Q1.234,56" (European) on a local check or invoice.
"con XX/100" and the FEL invoice
Two details that set a well-made Guatemalan document apart.
… QUETZALES CON 00/100
The centavos fraction closes the amount and prevents tampering. 1 quetzal = 100 centavos; "00/100" means no centavos.

The SAT's FEL regime is mandatory. The printed representation usually includes the total in words backing up the amount.

8 errors that get a check or invoice rejected
❌veintiuno quetzales
✅veintiún quetzales
The form "veintiún" uses apocope before a masculine noun. A bank will flag the long form when cashing.
Source: RAE Ortografía §10.2
❌doscientas quetzales
✅doscientos quetzales
Hundreds agree in gender with the noun. "Quetzal" is masculine, so "doscientos", never "doscientas".
Source: RAE Ortografía §10.4
❌cien cincuenta quetzales
✅ciento cincuenta quetzales
"Cien" is used only for exactly 100. From 101 onward it must be "ciento" followed by the rest.
Source: RAE Ortografía §10.3
❌treintaiún quetzales
✅treinta y un quetzales
From 31 onward tens and units are separated by "y". Joining them is incorrect.
Source: RAE Ortografía §10.2
❌un mil quetzales
✅mil quetzales
"Mil" never takes the article "un" before it. Only "millón" does.
Source: RAE Ortografía §10.5
❌uno millón quetzales
✅un millón de quetzales
"Uno" must apocopate to "un", and "millón" requires the preposition "de" when followed by a noun.
Source: RAE Ortografía §10.5
❌Q1.234,56
✅Q1,234.56
Guatemala uses the US format: comma for thousands and period for decimals. The European format (period thousands) confuses banks.

❌DOS MIL QUINIENTOS QUETZALES
✅DOS MIL QUINIENTOS QUETZALES CON 00/100
On bank checks the "con XX/100" fraction closes the amount and prevents centavos being added when cashing.
