Nüdge Theory is invoice reminder software built for UGC creators. It sends automated payment reminders before and after your invoice due dates, so you stop manually chasing brand clients and start getting paid on time.
You know how to film a 30-second video that makes someone buy something. You understand hooks, trust signals, authentic storytelling. Brands pay good money for that.
What they don't always do is pay on time.
Brand deals move through finance teams, approval chains, and procurement workflows that have nothing to do with you or the quality of your content. Net 30 becomes net 45. Net 45 becomes a follow-up email you've been putting off for two weeks because you're not even sure who in the organisation to address it to.
Nüdge Theory is built for UGC creators who are running a real business, campaign retainers, deliverable packages, usage rights fees, and who want to get paid professionally without doing the awkward chasing part manually.
The UGC creator's payment landscape
One brief, multiple deliverables, one invoice. You shoot, you edit, you deliver the files. The moment the brand has your content, your leverage disappears. You're now waiting on a finance department that didn't hire you and doesn't know you. Following up means figuring out who to contact, which makes the whole thing feel harder than it needs to be.
Ongoing brand partnerships are the goal for most UGC creators, but monthly retainers create monthly payment cycles that brands don't always respect. By week three, you're deciding whether to follow up and risk looking difficult, or wait and risk looking like payment doesn't matter to you. Neither option is good.
How it works
You set up a reminder when you send the invoice. Takes under a minute. Nüdge Theory handles everything that follows.
Before the due date: a professional heads-up lands in your brand contact's inbox. On the due date: a polite reminder. A week after: a follow-up that moves up the urgency without moving up the aggression. Two weeks after: one more, if needed.
The emails sound like they come from your business, considered and professional. Not from an automated billing system. Which matters when your entire brand is built on being real and human.
When payment arrives, you mark it paid in one click. The sequence stops. You get back to creating.
Built for your workflow
Set up the reminder when you submit your deliverables and forget about it. Nüdge Theory follows up with the brand while you're already on the next shoot.
Set up a recurring reminder that resets every billing cycle. Same brands, same professional sequence, zero manual effort each month.
Managing five brand relationships means five open invoices at various stages of payment. See every one at a glance: what's upcoming, what's overdue, what landed this week.
Brand deals are long-term. Nüdge Theory reminder emails are warm and professional, the kind that make a brand manager think 'right, I need to push this through approvals' rather than 'who is this and why are they being difficult.'
"UGC creators working directly with brands outside platforms typically wait 30 to 60 days for campaign payment. Across three or four brand relationships, that's real cash tied up in invoices that a single automated follow-up sequence could unlock, without one uncomfortable conversation."
