Match tolerance (absolute)
Sets how large an amount difference between an invoice and a bank statement line still counts as a match during bank statement import, in units of the currency. For example, with 5 a 10,000 HUF invoice matches lines between 9,995 and 10,005 HUF. If both tolerances are empty, only a difference of one smallest unit is allowed (1 forint, or 1 cent for the euro).
You set the tolerance per currency, in the Match tolerance (abs) field when editing the currency.
The amount is only one of the signals: when suggesting a match, the system also looks at the invoice number in the remittance text, the partner name and the date. If the difference exceeds the tolerance, the amount does not count as a match. If the bank line is at most 10% below the invoice amount, the system may still use it as a weaker signal, but you should then check the match.
If Match tolerance (%) is also filled in, whichever allows the larger difference applies.
