is it true that quickbooks can only accomodate one receivable and one payable general ledger account in a chart of accounts

Yes, it is @Bana.

When organizing your books, the general suggestion is to maintain one Accounts Receivable (A/R) and one Accounts Payable (A/P).

QuickBooks Online uses the default. You can create multiple AR and AP accounts, but you can't use them when creating transactions.

Instead, you can group them. Please see this article for more details: How to group Accounts Receivable or Accounts Payable account types.
