Software you own vs. a service you outsource
Invoice Butler does the work, but the underlying data and control sit with them. Modern is software your team operates, with full visibility into each outreach, portal submission and payment status.
Deeper ERP data, sharper collections
Modern reads your ERP and CRM in real time. Each message draws on payment history, customer tier, contract terms and any open disputes.
DSO you can report on
Modern provides dashboards and rolling cash forecasts built on your own collections data. Give leadership a clear view of where AR stands today and where cash will be next month.
Live in days. DSO moving by day 90.
How the switch plays out
Week 1
ERP and CRM linked. Invoices imported, Salesforce or HubSpot in sync, AR aging mapped. None of it lands on your team.
Day 7–30
First collections live and a DSO baseline in place. AP portals lined up for automation, plus a live view of every open balance.
Day 60
Portal submissions automated and aging trending down. Dispute playbooks tuned, and DSO shows its first measurable drop.
Day 90
DSO gains confirmed and manual work off your team's plate. Most teams have already earned back more than the yearly cost.
