How pricing works on Twine

Transparent rates, no hidden markup, and a payment path for every need.

The quote is the number.Nothing added on top.

Agencies bury a 20–40% markup inside the retainer, you never see it. On Twine, you set the price and you see the platform fee as a separate, explicit line. No surprises at checkout.

No hidden markup

Pay direct.0% commission.

Prefer your own payment flow? Pay your expert outside Twine, incurring no commission fees. Most useful for ongoing or trusted relationships.

0% off-platform payments

Pay via Vault.Your money is protected.

Funds are held in escrow and only released when you approve the deliverables. If the work isn't right, your money doesn't move. 10% commission on payments up to $10,000, just 5% on anything above.

10% up to $10k · 5% over $10k
