Hi syedaabidi!
When purchasing the fridge on instalment you could bookkeep it like this:
Account 1240 - debit
Account 2641 - debit
Account 1930 - credit
Account 2350 - credit
As for the instalment payment, you could for example bookkeep it like this:
Account 2350 - debit
Account 8410 - debit (interest amount)
Account 6570 - debit (for possible fees)
Account 1930 - credit (total amount)
I can highly recommend using the function Anläggningstillgångar if the fridge is classified as an inventory if you're not using it already.
You can find more info regarding the function here: Anläggningstillgångar.
I hope the above is useful to you.
Should you need any further information, please do not hesitate to reach out.
Have a great weekend!
