When the same figure is maintained in two places, one of them is always slightly wrong. We make one the source and keep the other current.
Two versions of the truth
Somebody updates a rate, a fee, or an owner split in one system and means to update the other. Most of the time they do. The times they do not are invisible until a statement goes out with a figure nobody can explain, and then the work is not fixing the number, it is finding every place it was already used.
What we build
We agree which system owns each shared field, then build the sync that keeps the others aligned to it. Changes propagate on a schedule you choose, with a record of what changed and when. Your team stops being the mechanism that keeps two systems agreeing, which also means the process no longer depends on anyone remembering.
One system owns each field, so conflicts resolve.
Your team steps out of the manual sync role.
Every change leaves a record you can check.
10 properties, 4 countries, 11 fewer hours of manual data entry every month.
What used to take days at month-end now takes about 40 minutes. Built in four weeks.
Tell us which field gets maintained twice. That is usually the whole scope.
