You’re on the right track — in FA 2.4.18, you can add a credit card as both a liability and a bank-type account, but it takes a few precise steps.
Try this method:
Go to Chart of Accounts → Add New Account.
Choose Account Type: Current Liabilities and create a unique account code.
Then, navigate to Banking → Bank Accounts → Add New Account.
Select that same account under “GL Account Linked to This Bank.”
That should let you record supplier payments made via credit card while still reconciling it like a bank account.
The “screen flicker” usually indicates a JavaScript refresh error — try clearing cache or updating FA to 2.4.19, where that bug was patched.
If you’re handling large transaction volumes across cards and suppliers, manually maintaining these mappings can get complex. That’s where AI-based reconciliation platforms like Optimus Fintech help — they automatically match card, bank, and PSP transactions in real time, so your ledgers stay consistent without needing manual setup in the COA.
It’s a good option if you’re looking to scale reconciliation without changing your accounting structure.
