Invoicing App for Content Creators and Influencers

Creators get paid late because invoices are built by hand and chased from memory. Mythex builds an invoicing app for brand work: invoices that carry the brand's PO number, price usage rights separately, track net terms and list what is overdue.

Who it's for

YouTubers, streamers, podcasters and Instagram or TikTok creators doing several brand deals a quarter, who invoice from a document template and keep a spreadsheet of who has paid. Also works for small creator teams and managers billing on behalf of a creator.

What you can build

Brands and agencies saved with billing contacts and payment terms
Invoice lines for the content, paid usage rights with a duration, and exclusivity
The brand's PO number and campaign ID on every invoice
Net 30, 45 or 60 terms with due dates worked out for you
An overdue list and a reminder email you can send in one click
A downloadable PDF with your logo and invoice numbering

Price the rights, not just the post

A brand that asks to run your video as a paid ad for six months is buying something beyond the post. So is a brand that asks you not to work with competitors for 90 days. Put content, usage rights and exclusivity on separate lines with their own prices and durations. Brands are used to seeing it this way from agencies, and it stops you giving away rights because they were buried in an email.

Content: the deliverables as agreed
Usage: platform, paid or organic, and how long
Exclusivity: category and number of days

Getting paid on time

Large brands pay through accounts departments that reject invoices without a PO number or with the wrong entity name. Store the billing entity and PO on the brand record so every invoice has them. Track the terms you agreed, and ask for an overdue view sorted by days late. A polite reminder on day one past due works better than an awkward message on day 40.

What to set up first

Add the brands you currently work with and their terms. Recreate your last three invoices in the app to check the layout and numbering. Then ask for a dashboard of unpaid money by brand and income by month, split by sponsorships and affiliate payouts. Once that is working, link invoices to a deal tracker so a deal's agreed fee fills the invoice for you.

A prompt to start from

Build an invoicing app for a content creator. Store brands and agencies with billing entity, contact, PO number and payment terms. Invoices have a number, date, due date from the terms, and separate lines for deliverables, paid usage rights (platform and months) and exclusivity (category and days), with tax and total. Generate a PDF, mark invoices sent, paid or overdue, send reminder emails, and show unpaid totals by brand.

Questions

Can it generate PDF invoices?

Yes. Ask for a printable invoice and Mythex builds a PDF layout with your details, logo and sequential numbering, ready to download or attach to an email.

Can I add usage rights and exclusivity as separate charges?

Yes. Describe the line types you use and the invoice shows them separately with their durations. It makes the price of each right clear to the brand.

Does it handle tax and different currencies?

Tell Mythex which tax applies and at what rate, and whether you bill in more than one currency. It calculates tax per line and shows the currency on each invoice.

Do I need to know how to code?

No. You describe the invoices in plain language, check them in the live preview, and change the layout or fields by chatting.

Is it free?

The Free plan has daily credits and needs no credit card, enough to build and publish your invoicing app. Pro is $25 a month for more credits, a custom domain, code editing and export.
