The problem
Random reminders rarely get you paid
When follow-ups are inconsistent, badly worded, or simply forgotten, overdue invoices drag on. Clients aren't sure how serious you are, and you're left guessing what to send next.
Inconsistent wording
Every reminder sounds different, so none of them carry real weight.
Forgotten follow-ups
Without a system, the next step slips and invoices quietly age out.
Awkward escalation
It's hard to know when to get firmer — so most people never do.

FAQ
Questions, answered
A few of the things people ask most. See the full list on the FAQ page.
What is Duesteer?
Duesteer is an iOS app that helps you recover overdue invoices with a clear, professional escalation process. Instead of sending random reminders, you follow a guided ladder of steps and generate appropriate follow-up emails.
Who is it for?
Duesteer is built for freelancers, consultants, contractors, agencies, and small service businesses — anyone who invoices clients and occasionally has to chase late payments.
Is Duesteer for UK businesses?
Yes. Duesteer is built around UK late-payment practice, including statutory interest and fixed compensation under the Late Payment of Commercial Debts (Interest) Act 1998, and the letter before action that precedes a court claim. The escalation workflow itself works just as well when your client is based elsewhere.
Does Duesteer send emails automatically?
No. Duesteer helps you generate professional reminder and escalation emails, but you review and send them yourself from your own email app. You stay in full control of every message.
Does Duesteer connect to accounting software?
No. Duesteer does not connect to accounting software, bank accounts, or payment processors. You add invoices manually, which keeps your data self-contained and under your control.
