Receive multiple payments from a customer does not show up on each job's ledger.

Welcome and thanks for reaching out to the Community, @stewartshevin.

When recording one payment for three invoices (customer jobs), QuickBooks Desktop (QBDT) will group the payment as one. Also, it will only show on the customer transaction list.

However, to ensure that I'm on the same page, may I know what specific ledger you're referring to? It would be helpful if you can provide a sample screenshot. This will make sure that I can provide the best resolution for your concern.

Just in case, I'll add this article that tackles steps on how to effectively track job costs in QBDT: Tracking job costs. It also contains links to other job-related concerns.

First, if you set up each of these as jobs under the customer name, there is no need to split payments.  You just receive from the main customer name and all job invoices will be listed below.  Check off the invoices being paid.

Secondly, payments do not show up on the P&L by job.  It shows invoicing.  If you want to show payments, change the report basis from accrual to cash.
