Bookkeeping


want to match payments largely automagic
easy for those that we generated
but incoming regular transfers - purpose field is freetext
cannot rely on the SEPA End-to-End reference (yet?)

try to find anything that looks like our document numbers
retrieve bookkeeping records

amount in window -> book it
window lower bound: sum of invoice amounts
upper bound: add calculated late-pay interest

otherwise do nothing and leave it to a human
but >95% automatic
