Most late-payment problems start before the invoice exists

The more I work on Billzy, the less I think overdue recovery starts when the invoice becomes late.

A lot of the outcome was decided earlier.

Before the work even started, did you confirm:

- who approves the invoice

- where the invoice should be sent

- what payment terms were agreed

- how payment will be made

- whether a PO or reference number is required

Once an invoice is overdue, people treat it like a collections problem.

But a surprising number of late payments are really setup problems that get discovered too late.

Wrong contact.

Missing PO.

Terms never stated clearly.

No payment link.

No obvious owner.

By the time the invoice is late, you are no longer solving the cheapest version of the problem.

You are fixing process debt in the middle of collections.

That is why I think one of the best things a recovery product can do is not just schedule the next reminder.

It should surface the missing setup step.

What was never confirmed?

What approval path was never made explicit?

What payment instruction is missing?

Because late-payment recovery gets much easier when the payment path was designed early.

This feels like a broader lesson too.

A lot of downstream mess in business is really upstream ambiguity.

If the expectation, owner, and path are unclear at the start, you usually pay for it later in follow-up.

That has changed how I think about Billzy.

Not just:

"help chase overdue invoices."

More like:

"help people close the setup gaps that create overdue invoices in the first place."

Curious what other founders and freelancers think:

What is the one thing you wish was always locked in before you start client work, because it causes the most trouble later?
