Use the High-to-Low Method
- Identify the currency and numbering system.
- Separate the numeric value into major units and minor units.
- Read the words by scale: crore or billion, million, lakh, thousand, hundred and units.
- Write the reconstructed digits without looking at the original numeric field.
- Compare the reconstructed digits with the source amount.
- Check cents, pence or paise separately.
This method catches a missing “thousand,” a transposed digit and an incorrect cents fraction that ordinary spell-checking will not detect.
Review the Document Context
Confirm that the phrase describes the final amount due, not a subtotal or old version. Check the payee, invoice number, currency code and date. If the document was generated from a template, verify that the words refreshed when the digits changed.
On checks, inspect empty line space and the signature. On invoices, trace tax, discount, shipping and credit adjustments. On contracts, confirm the wording is consistent each time the amount appears.
Use a Second Person for High-Value Documents
For an important payment, an independent reviewer should compare the source record, figures and words. Ask the reviewer to reconstruct the number instead of merely agreeing that the sentence looks plausible. Keep the approved source and final document together in the record.
If a mismatch is found, replace the document cleanly rather than hiding the correction. A converter can produce a reliable draft, but the issuer remains responsible for the final value and local requirements.
