Before Simply Invoicing

3 Hours Lost Every Week on Invoicing Admin

Running a growing service business in the UK, Daniel spent over 3 hours every week creating invoices, checking customer details, keeping records organised and manually following up on payments. Invoicing took time away from customers and slowed down business growth.

Key problems:

✗ Manual, repetitive invoicing
✗ Time wasted preparing and sending invoices
✗ Payment follow-ups done manually
✗ No clear overview of invoices and finances

THE SOLUTION WITH SIMPLY INVOICING

Daniel moved his invoicing process into Simply Invoicing. Customers, services, invoices and documents are now organised in one place. Invoices are created quickly, sent instantly, and payment reminders help reduce late payments — without manual chasing.

What changed:

✓ Invoices created in seconds
✓ Automatic payment reminders (Standard & Premium)
✓ All invoices organised in one system
✓ Clear overview of issued and paid invoices

90% Less Admin Time

Invoicing dropped from 3+ hours to just 15 minutes per week, saving over 12 hours every month.

Before: 3+ hours/week

After: 15 minutes/week

💡 12 hours saved per month
