This is the total unpaid invoice balance held in your field service system.
Why it is shown separately
Your field service system invoices the job. Your accounting software keeps the books. The two hold overlapping but not identical pictures of what you are owed, because an invoice raised on site does not always reach the accounting side immediately.
Reading this figure next to money owed to you tells you whether the two agree. When they do, your receivables are fully accounted for. When they differ, the difference is invoices that exist in one place and not the other — and those are the ones nobody is chasing, because neither system shows a complete list.
Why the gap matters more than the number
An invoice missing from your books is not just a reporting problem. It is money owed that appears on no aging report, gets no reminder, and surfaces months later when a customer mentions it or does not.
Both figures come into the same unified ledger, which is what makes the comparison possible rather than a manual reconciliation.
What to do with it
Check the two against each other monthly. A persistent difference is worth tracing to one invoice rather than treated as a rounding artefact — see overdue invoices for chasing what you find.
