The work is finished.
The chasing shouldn’t take over.
Finding an old invoice. Checking a due date. Rewriting the same polite email. Small tasks add up when you're running the whole business.
Invoice Follow-ups gives those loose ends one home: a simple view of your invoices, a message that sounds like you, and a clear record of what happens next. Keep QuickBooks, FreshBooks, Wave or whatever you invoice with.

LATE FEES AND YOUR RIGHTS IN THE US
What you can charge when a client pays late.
In the United States there is no federal statutory interest on late private invoices. A late fee is enforceable when it is agreed in your contract or on terms the client accepted; 1 to 1.5 percent per month is common, within your state's usury and consumer-protection limits. The federal Prompt Payment Act sets interest only for federal agencies paying contractors, and most states have prompt-payment rules for public contracts. For private invoices your leverage is clear payment terms, consistent reminders, a demand letter, and small claims court.

A FEW USEFUL DETAILS
Before you jump in.
A little clarity about your account, sending, and the sample demo.
Can I try it without signing up?
Yes. Explore sample invoices in the demo before creating an account. Create your account when you're ready to save real invoices and message templates. The demo doesn't send email.
Does Dunlio work with QuickBooks, FreshBooks or Wave?
Yes, by CSV. Export your open invoices from the tool you already use, import them, and Dunlio handles the reminders. You don't move your invoicing or accounting. Direct integrations are planned.
Can invoices be in US dollars?
Yes. Invoices can be in USD, EUR, GBP, CAD, AUD and other currencies, and amounts show in the right format in every reminder.
How do automatic follow-ups work?
Choose the number of days after the due date and your time zone, then turn on automation per invoice. Reminders go out on business days between 9 am and 5 pm your time. You can keep sending manually instead, or pause an invoice whenever it needs a conversation.
Can I add a late fee?
Only if your contract or invoice terms state one; Dunlio's past due and final notices reference the late fee your terms allow, and the late-fee calculator helps you work out the amount. Dunlio doesn't collect debts or act as a collection agency.
Where is my information stored?
Invoices, saved templates and delivery activity are stored on servers in the European Union (Google Cloud, Belgium), which gives US customers strong privacy protection by default. The demo keeps its data in your browser.
Which languages can my reminders use?
Templates come in US and UK English, German, French, Spanish, Italian, Dutch, Polish and Portuguese, each written for that country's reminder customs. You can edit every word before sending.
