Order-to-Cash Cycle Cost Calculator — O2C Process Cost Analysis

Calculate the true cost of your order-to-cash cycle. Order entry, credit check, picking, shipping, invoicing, and collections — find what each step costs and where to optimise.

Quick answer: Order-to-cash process cost: $8–$35 per order depending on automation level. Manual O2C: $25–$50. Automated: $5–$15. The working capital impact of slow O2C cycles can exceed the process cost significantly.

How to Use This Calculator

Enter processing time per step — time-study each O2C step — order entry, credit check, invoicing, and AR/collections follow-up.
Enter current and target DSO — Days Sales Outstanding from your AR aging report. Target based on your payment terms.
Working capital is the big lever — for most companies, reducing DSO by 10 days frees more cash than eliminating all process cost.

Worked Example

2,000 orders/month, $850 avg, 31 total minutes at $28/hr, DSO 45 → 32, 8% cost of capital.

Process cost/order: $14.47
Annual process cost: $347,200
Annual revenue: $20.4M
Working capital freed: 13 days × $55,890/day = $726,575
DSO saving: $58,126/yr financing

DSO reduction delivers 17% of total O2C improvement value in this example. Automation (EDI orders, auto-credit scoring, e-invoicing) reduces process time 60–70% and typically reduces DSO 3–7 days through faster invoicing.

Frequently Asked Questions

Days Sales Outstanding = (Accounts Receivable ÷ Annual Revenue) × 365. It measures how long it takes to collect payment after invoicing. A DSO of 45 with 30-day terms means customers average 15 days late. Best-in-class: within 5 days of payment terms. Common causes of high DSO: invoice errors, disputes, manual collection process, and inefficient dispute resolution.

Eliminate invoice errors (auto-match POs before invoicing), send invoices day of shipment (not weekly batch), implement electronic invoicing with customer portals, escalate 30+ day overdue accounts immediately, offer early payment discounts (2/10 net 30), and assign dedicated AR staff to top-10 customers by AR balance.
