The gap between quote and payment
A customer books a European package in January for June travel. The supplier invoice, in EUR, gets paid closer to the travel date — five months after the AED price was quoted and locked in. In that window, the exchange rate can move meaningfully, and whichever direction it moves, it changes the actual margin on that booking from what was originally planned.
Why this stays invisible
Most agencies don't track this at the booking level — forex movement gets absorbed into a general "other expenses" line, if it's tracked separately at all, which means nobody can tell you which product lines or booking windows are most exposed to currency risk.
Making the exposure visible
Tracking forex gain and loss per booking, rather than as a lump sum, turns an invisible risk into a manageable one — an agency can see which supplier currencies and which booking lead times carry the most exposure, and price accordingly with a small buffer where it's warranted.
How Muhasib tracks this
Muhasib records supplier costs in their original currency and posts the forex gain or loss automatically at payment time — giving agencies real visibility into currency exposure instead of a blended, unexplained variance at month-end.
