I automated my invoice reminders with Make's free tier (30-minute setup)

Late invoices used to cost me real money — not the invoice itself, but the awkward follow-up. I'd spot an overdue payment, draft a "just checking in!" email, delete it, rewrite it softer, and send it three days late. The work of reminding was small; the dread was large. So I automated it. Total setup time: about 30 minutes, on Make's free tier.

The setup

The pipeline is embarrassingly simple:

1. Trigger: a scheduled check (daily) against my invoicing tool for invoices past due.
2. Branch: if overdue < 7 days → send the polite nudge. If overdue ≥ 7 days → send the firmer follow-up with the late-fee note.
3. Stop condition: the moment the invoice is marked paid, the client leaves the sequence. This is the part people skip, and it's the part that matters — nothing torches goodwill like a reminder for an invoice paid yesterday.

The polite nudge is two sentences and references the invoice number and a fresh payment link. The firm one adds the late fee policy. Both sound like me because I wrote them once, on a calm day, instead of drafting them anxiously at midnight.

Why Make and not Zapier

For this workflow they're interchangeable, honestly. I picked Make because the free tier gives more operations and the visual scenario builder made the branching logic obvious. If you're choosing between the automation tools, this Zapier vs Make vs n8n comparison prices them at real usage instead of sticker price — worth ten minutes before you commit.

What changed

• Days sales outstanding dropped. Not because clients pay faster out of fear — because the reminder arrives on day 1 instead of day whenever-I-get-around-to-it.
• The dread is gone. The automation doesn't feel awkward. It sends the same two sentences every time, and clients just pay.
• One habit still matters more than the tool: I send every invoice the day the work is delivered, while the project is fresh in the client's mind. The automation handles the chasing; same-day sending handles the psychology.
