Default assumptions and sources

Every starting value is labeled—not hidden

Sources were checked on September 17, 2026. Published benchmarks give this example a starting point; your own invoice history is the better input.

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.

Manual invoicing benchmark

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.

Eonebill time assumption

5 minutes per invoice

Illustrative scenario input only. It is editable and is not presented as a measured customer average, benchmark, or guarantee. Time your own workflow and replace it.

Business-value assumptions

$1,000 invoice · $50/hour · 10% cash cost

Illustrative values, not industry averages. Replace the invoice amount, admin-hour value, and funding or opportunity-cost rate with figures from your own business.

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.
