FAQ

What is the Payables Conversion Period?

The Payables Conversion Period shows how many days your company takes to pay suppliers after a purchase (APQC, 2023).

Why does a shorter period matter?

Shorter periods cut late-fee costs and strengthen supplier relationships, improving on-time delivery by 15 % (Gartner 2021).

Is a longer period always negative?

No; using full credit terms frees cash for operations, but excessive delay incurs penalties and damages trust (PwC 2022).

How often should I run the calculator?

Run it monthly to align with closing cycles and spot emerging cash-flow issues early (CFO.com, 2022).

Which data source is best for Purchases?

Use cost-of-goods-sold from your latest income statement for the most reliable annual figure (FASB ASC 330).

Can I benchmark internationally?

Yes; European manufacturers average 68-day DPO, versus 54-day U.S. median (Euler Hermes Trade Report 2022).

How do early-payment discounts affect DPO?

Taking a 2/10 net-30 discount shortens DPO to about 10 days but saves 2 % invoice value (Investopedia, 2023).

What’s a quick improvement tip?

Automate invoice matching; companies using e-invoicing cut processing time 60 % (Ardent Partners State of ePayables 2023).
