The short answer: after a sponsored campaign, the brand's finance team pays against an invoice, not against your DMs. Send one that lists each deliverable as its own line item, includes the campaign name and any PO number the brand gave you, states usage rights as a separate line if they are paid, and sets clear payment terms. You can make one free in under a minute, no account needed.

Why brands insist on an invoice

Even when the partnership was agreed entirely over email or through an agency, the payment is processed by an accounts-payable department that needs a document: who to pay, how much, for what, referencing which campaign. No invoice, no payout queue. Agencies are the same, just with an extra approval layer. Treat the invoice as the final deliverable of every campaign.

What goes on an influencer invoice

Everything on the standard invoice checklist, plus the sponsorship-specific details that stop finance teams emailing you questions:

  • The campaign reference. Brand campaign name and month: "Summer 2026 launch, July flight". If the brand issued a PO (purchase order) number, put it prominently; large companies cannot process an invoice without it.
  • One line per deliverable. "1 x Instagram Reel (60s), published 12 July 2026", "3 x Instagram Stories with link sticker", "1 x dedicated YouTube integration (90s)". Mirror the wording of your agreement or the brand brief.
  • Usage rights as their own line. If the brand licensed your content for paid ads or their own channels, bill it separately: "Paid usage rights, Meta ads, 90 days". Rights buried inside a content fee are rights you cannot renegotiate at renewal.
  • Exclusivity, if paid. Category exclusivity ("no competing beverage brands for 60 days") is a real cost to you; when it is compensated, it is a line item.
  • Your legal details. Bill under the name that matches your bank account. US creators are often asked for a W-9 alongside the invoice; non-US creators working with US brands may be sent a W-8BEN. Send them with the invoice to save a round trip.
  • Currency. International sponsors pay faster when the invoice states the agreed currency explicitly, USD in most global campaigns. A generator with proper multi-currency support formats this correctly.

The net-30 reality

Consumer brands and agencies commonly pay net 30, and some impose net 45 or 60. Three ways to protect yourself:

  • Start the clock immediately. Send the invoice the day the last deliverable goes live, not weeks later. On net 45, every day you delay sending is a day added to your wait.
  • Negotiate terms before you post. Payment terms belong in the agreement stage. For first-time sponsors with no history, asking for 50 percent upfront is normal and widely accepted.
  • Track due dates. Sequential invoice numbers and a simple spreadsheet of sent/due/paid is enough at creator scale.

When the brand pays late

Follow up with the accounts-payable contact (ask for it when you send the invoice), not your marketing contact, who has no power over payment runs. Reference the invoice number and PO, attach the invoice again, and ask which payment run it is scheduled in. Escalate to your marketing contact only if AP goes quiet; brands care about creator-community reputation, and a polite, well-documented paper trail gets results faster than a public complaint.
