I kept rewriting “just checking in” emails and still waiting weeks to get paid — so I packaged the cadence I actually use.
SoftDue is a $9 one-time kit: Day 0 / +3 / +7 / +14 polite reminder templates plus a simple CSV/HTML tracker. Paste your Stripe/PayPal/Wise link, send the cadence, mark Paid, stop.
Not an accounting suite. Not SMS automation. Just the chase emails + a tracker so follow-ups don’t feel awkward.
Honest early days — no fake social proof. If you invoice clients and skip reminders, what’s the one tweak that would make this worth $9?

Freelancers: what’s your personal tell that an invoice has officially entered the “okay, now I have to chase this” zone—and which reminder wording has actually gotten a reply without making things weird?
If the pre-invoice work is the messy bit, I made a free Client Ops Notion pack for freelancer onboarding, scope, and revisions: https://same-cardboard-928.notion.site/Client-Ops-for-Freelancers-3d7ad6a053448014b4b3fe181d7c864b
It’s free to duplicate; the SoftDue kit stays focused on invoice reminders.
