The route through
the work.
Simplified process view based on supplied implementation facts; individual workflow internals are not represented.
What changes when
the handoffs connect.
The accounts receivable process handles 150+ invoices per month. Unpaid invoices require timely, consistent follow-up without losing sight of cases that need a person.
Manual follow-up administration adds repeated checking, message preparation, and status tracking to the receivables workload.

Value is a question
to measure.
The intended value is less manual follow-up administration and a shorter follow-up cycle. The six-week-to-two-week cycle change was a target, not a confirmed result.
Potential staff time difference at a reference volume of 150 invoices per month. This is a modeled scenario, not measured savings.
At 150 invoices per month, assume 8–12 minutes of manual follow-up administration per invoice and 2–4 minutes of remaining human review. Estimated range = 150 × (8−4) ÷ 60 to 150 × (12−2) ÷ 60. This is a scenario, not measured savings.
Approximately six weeks to two weeks was the intended reduction. Achievement has not been verified.
