Organizations typically recover substantial value through faster approval workflows

Get Started

Early payment discounts represent a direct return on working capital that often exceeds alternative investment yields. The value compounds through improved vendor relationships, supply chain resilience, and preferential treatment during shortages or capacity constraints.

Approval bottlenecks typically stem from manual routing, limited visibility into approval status, and lack of exception handling workflows. Automated systems route invoices based on business rules while providing real-time status tracking and escalation paths for time-sensitive approvals.

  5. 5Input expected automation improvement in approval speed
  6. 6Review annual value from captured discounts and eliminated late fees

Why Invoice Approval Bottleneck & Lost Discount Matters

Early payment discounts represent significant potential savings that many organizations fail to capture. Vendors offering 2/10 Net 30 terms (2% discount if paid within 10 days) are offering substantial annualized return on early payment. However, slow approval processes can mean invoices sit for considerable time before approval, missing discount deadlines. Organizations often capture only a portion of available discounts, leaving substantial savings unrealized.

Automated approval workflows can dramatically accelerate invoice processing through intelligent routing, parallel approvals, automated escalations, and mobile approval capabilities. This speed improvement can enable organizations to capture significantly more early payment discounts. Companies can realize meaningful annual savings through improved capture rates.

Beyond discount capture, faster approvals can eliminate late payment penalties, strengthen vendor relationships through reliable payment timing, improve working capital management through predictable cash outflows, and reduce AP team time spent chasing approvals. The total financial impact can be substantial.

Frequently Asked Questions

What early payment discount percentage is typical?

2/10 Net 30 (2% for payment within 10 days) is most common. Some vendors offer 1/10 or even 3/10. On 2/10 Net 30 terms, taking the discount can represent substantial annualized returns - typically worth capturing.

Why do companies miss discount deadlines?

Slow approval processes are the main cause. Invoices can sit in email inboxes for considerable time waiting for approver response. By the time approvals complete, discount windows may have closed. Approval automation can solve this by dramatically accelerating processing.

Should we take all early payment discounts?

In most cases, yes. Early payment discounts can represent compelling annualized returns that typically far exceed cost of capital. The main exception is cash flow constraints, but even then, paying critical vendors early can be wise.

How does automation ensure discount capture?

Automated systems prioritize invoices with discount terms, alert approvers to discount deadlines, escalate to backup approvers if primary doesn't respond, and provide dashboards showing discount capture rates. Visibility and urgency drive behavior change.

What about dynamic discounting?

Some AP platforms enable dynamic discounting where you offer to pay vendors early for negotiated discounts even on invoices without standard terms. This optimizes cash utilization by capturing returns on excess cash before quarter-end.

How do we measure discount capture improvement?

Track: (1) Total discount value available monthly, (2) Actual discounts taken monthly, (3) Capture rate percentage, (4) Average approval time for discount-eligible invoices. Pre/post automation comparison shows improvement.
