Collection benchmark
29.3 days to payment; 8.5 days late
Xero Small Business Insights, US small businesses, June quarter 2026. The 20.8-day target is the 29.3-day benchmark minus the reported late-payment gap—not an Eonebill performance claim.

5+ hours per month risk threshold
FreshBooks reported that service businesses spending at least five hours monthly on manual invoicing were nearly three times as likely to report cash-flow problems. The 15-minute default is illustrative: 20 invoices make five hours.

Invoice savings calculator FAQs
What does this invoice savings calculator measure?
It models two separate opportunities: administrative hours that may be saved when invoice preparation takes less time, and the financing value of receiving the same invoice volume earlier.
Does Eonebill guarantee these savings?
No. The result is a scenario based entirely on editable assumptions. It is not a promise, customer average, quote, or guarantee of product performance.
How is cash-flow value calculated?
The model multiplies annual invoice volume by the fraction of a year represented by days brought forward, then applies your annual funding or opportunity-cost rate.
Where do the default collection days come from?
Xero Small Business Insights reported that US small businesses averaged 29.3 days to be paid in the June quarter of 2026 and were paid 8.5 days late on average. The example target subtracts that late-payment gap; it is not an Eonebill result.
This planning tool does not include Eonebill subscription cost, payment-processing fees, taxes, bad-debt risk, or implementation time. Use the output as a scenario to test, not a forecast.
