If you send payment reminders by hand, you are financing your customers for free

Somewhere in your accounting team there is a list of overdue invoices right now. Someone will go through it, maybe tomorrow, maybe on Friday when there's time. Until then your company is financing a customer who owes you money, completely free of charge.

This is no exaggeration. Every day of delay is a cost of capital you could use elsewhere: for salaries, stock or growth. Small and mid-sized companies in Slovenia and across Central and Eastern Europe routinely overlook this cost, because it hides in cash flow rather than in the income statement.

Chasing payments by hand isn't free, it's just a hidden cost

The manual process usually looks like this: once a week someone opens Odoo or Excel, filters overdue invoices, copies customer names and writes emails based on memory of who is a 'difficult' payer and who isn't. That's an hour or two a week from someone who could be doing something else. And because the process is manual, it's uneven: some invoices get a reminder on the first day they are overdue, others only three weeks later.

AIVIO's Payment Reminder workflow (WF01) takes over this task completely. Every day it checks the status of invoices in your system, sends escalating reminders in your brand's tone, and stops as soon as the customer pays. No exceptions, no forgotten cases, no week of delay because someone was on holiday.

"The first reminder goes out automatically at 9:00 on the due date, then after 3, 7, 14 and 21 days. Each one is polite, numbered, and stops as soon as the invoice is paid."

What actually changes after 48 hours

• For clients who introduce Payment Reminder, days sales outstanding (DSO) fall by 6 to 8 days on average.
• One client, a transport company, used this workflow to drop a manual check that used to take 3 hours a week, cutting it to zero.
• Reminders take the customer's payment history into account: a friendly tone for good payers, a firmer one for repeat late payers.

The workflow is part of the Starter plan, so there's no need for a more expensive upgrade to try it. It runs on EU servers in Germany, in line with the GDPR and ZVOP-2, and connects directly to your existing system (Odoo, Excel or another accounting tool) without any data migration.

What it is worth in your business

Take the average value of an overdue invoice, multiply it by the number of days you shorten payment times, and by your cost of capital. For most clients with 5 to 100 employees, the amount quickly exceeds the price of the plan. That's not a marketing promise, it's arithmetic you can check yourself with your own numbers.

Today AIVIO runs 36 workflows like this on 454 automation nodes. Payment Reminder is often the first one clients introduce, because the effect shows up in the bank account, not just in the schedule.
