What actually works
6 things that move the number.
Small businesses wait an average of several weeks past terms to be paid, and the chasing usually falls to the owner, in the evening, after doing the actual work. The fix is to remove the human from the routine part.
Put a pay link on the invoice
An invoice that says βbank transfer toβ¦β is a task. One with a βPay nowβ button β card or mobile money β is a tap. Paid-on-receipt rates roughly double.
Invoice from the job, the same day
The longer between finishing the work and sending the invoice, the less urgent it feels to the customer. Raise it from the job record before you leave.
Set a reminder sequence and let it run
Day before due: friendly heads-up. Due date: βhereβs the linkβ. Day 7: βthis is now overdueβ. Day 14: formal notice. Written once; sent automatically; you only see the ones that reach step four.
Change the tone by stage, not by mood
The first reminder assumes they forgot. The fourth states the consequence. Neither should depend on how your day went.
Know who owes what, at a glance
An aging report β 0β30, 31β60, 61β90, 90+ days β tells you where the money actually is and which customers to stop extending terms to.
Use deposits and progress payments on bigger jobs
A 30% deposit before starting and a stage payment mid-way means the final invoice is a fraction of the job, not all of it.
The shortcut

Every step above is built into the Service Business OS β seeded for a service business, running the day you launch it, with your approval on anything that reaches a customer.
Pay link on every invoice
Card via Stripe, or mobile money β the customer pays from the invoice link and it is marked paid automatically.
Invoice raised from the job
Line items, parts and extra time come from the work order; nothing is retyped.
Overdue notices with the right tone
Staged dunning notices β reminder, overdue, formal β with the interest and fee rules your country expects, drafted for your approval.
Aging report
Who owes what, in 0β30 / 31β60 / 61β90 / 90+ buckets, and per-customer credit history.

Common questions
Questions worth asking.
Will automated reminders annoy good customers?
The first reminder is a friendly heads-up with the pay link, sent before the due date; customers who pay on time never see anything stronger. The stronger notices only reach customers who are already late.
Can customers pay without a card?
Yes β mobile money (M-Pesa, MTN MoMo, Orange Money and others through Flutterwave or CinetPay) sits next to card on the same pay link, and cash payments can be marked paid at the desk.
Is this legally compliant in Germany?
Invoices are numbered sequentially and immutable once issued, cancellations are done with a Storno (credit note) rather than deletion, and dunning notices follow the staged Mahnung model β the structure GoBD expects.
Features reflect the current platform as of August 2026 and continue to expand β the live demo above always reflects what's actually deployed.
