How to calculate the value of proposal to cash automation

A business case becomes unreliable when it counts the same money twice. Bringing a customer payment forward releases working capital. It does not create a second sale. Saving administrative hours creates capacity, but it reduces cash costs only when overtime, contractors or another actual expense can be avoided.

Allianz Trade's 2025 analysis connects longer collection periods with pressure on corporate working capital. Its global findings support examining the issue, but they do not provide a return-on-investment forecast for a particular small firm.^[1] Your case needs your own transaction history and delivery costs.

Separate three sources of potential value

First, estimate timing improvement. A simplified steady-state calculation is annual credit sales divided by 365, multiplied by a plausible reduction in collection days. At $1.2 million of annual credit sales, five fewer days corresponds to approximately $16,438 of receivables released. This is an illustrative balance-sheet effect, assuming stable sales and comparable measurement; seasonality and growth can materially change it.

Second, estimate capacity. If 20 monthly hours of avoidable work fall by 40%, eight hours become available. At an assumed $45 loaded hourly cost, that is $360 a month of capacity value. State what those hours will be used for. If no expense changes, describe the benefit as capacity rather than booked savings.

Third, investigate genuinely missed or unrecoverable billing. Review approved changes, expenses and completed milestones against invoices. Count only amounts the business was entitled to bill and that would otherwise have been lost. Do not treat all uninvoiced work as leakage; some may not yet be billable. The change order control shows how to make that distinction.

Keep the timing benefit separate from annual earnings

Using an illustrative 10% annual funding rate, $16,438 of sustained receivables reduction could avoid approximately $1,644 of annual financing cost if the business actually reduces borrowing by that amount. Do not add the full cash release to annual profit or count it again in later years.

Now assume implementation costs $3,000 and recurring support costs $250 per month. Year-one fees are $6,000. Annual capacity value in the example is $4,320; potential financing savings are $1,644. Together they are $5,964, still below year-one fees, and most of that total may not be cash savings. On these assumptions, the business case needs revision or a narrower scope.

Test the assumptions that matter most

Build a low case with no collection-day improvement and half the expected time saving. Include internal project time, data cleanup, additional software, transaction fees, monitoring and maintenance. Avoid adding an assumed reduction in bad debt unless you can explain the mechanism and show evidence.

Compare customers and invoice types consistently. An improvement caused by a large early payment is not proof that the new process works. Track invoice cohorts over a full payment cycle and review the open exceptions as well as completed payments. The measurement guide explains why DSO alone can mislead.

A sensible pilot has a stop rule. Agree which operational improvements must appear, when you will review them and what happens if the benefits do not justify the ongoing cost. A smaller fix that pays for itself is more valuable than an impressive system whose economics remain speculative.
