Social media agency payment terms and VAT explained

Key takeaways

Social media agency payment terms in the UK are usually monthly in advance, with payment due in 14 to 30 days. A VAT-registered UK agency adds 20% VAT to its fees. Ad spend should be billed to you by the platform, separately. Check all three before comparing prices.

• 20% VAT is added to fees by a VAT-registered UK agency.
• Monthly in advance, due in 14 to 30 days, is the usual pattern.
• Ad spend is best billed directly by the platform to your account.
• Statutory interest on late business payments is 8% plus base rate.

How do agencies usually invoice?

Most agencies invoice the monthly fee at the start of each month, with any set-up fee on the first invoice. Projects are often split, for example half on signing and half on delivery. Extras are invoiced in arrears. Ask for a sample invoice so nothing surprises your accounts team.

How does VAT apply to agency fees?

A VAT-registered UK agency charges 20% VAT on its services. A £1,500 fee is £1,800 including VAT. If you are VAT-registered you can normally reclaim it. If you are not, VAT is a real cost, so compare quotes including VAT. Small suppliers below the £90,000 registration threshold may not charge VAT at all.

• Quoted fees are usually stated excluding VAT.
• VAT-registered buyers can normally reclaim the VAT.
• Unregistered buyers should compare prices including VAT.
• Freelancers below the threshold may not charge VAT.

What changes with an overseas agency?

When a UK business buys services from a supplier outside the UK, the place of supply is normally the UK and the reverse charge applies. A VAT-registered buyer accounts for the VAT itself on its return. For an unregistered business, the value of reverse-charge services counts towards the £90,000 registration threshold. Ask your accountant.

How should ad spend be paid?

Ad spend should be charged by the platform to a card or account in your business's name. You see exactly what was spent, you keep the invoices and the data, and the agency's fee stays separate. If an agency pays the platform and re-invoices you, ask whether a margin is added.

What happens if a payment is late?

For business-to-business contracts, a supplier can claim statutory interest of 8% plus the Bank of England base rate on late payments, and a fixed sum for recovery costs. If no payment date is agreed, payment is late 30 days after the invoice or delivery. Many contracts also allow the agency to pause work.

Which payment terms should you question?

Question terms that ask for a large payment before any work, such as six or twelve months in advance, or the full term payable if you leave early. A month in advance is normal. Paying far ahead removes your ability to stop if the service disappoints.

What does a clear monthly invoice look like?

A clear invoice separates three things: the fixed monthly fee, any approved extras with a description, and VAT. Ad spend does not appear, because the platform bills you directly. If your invoice shows a single line for social media services, ask for it to be broken down.

• Line 1: monthly fee, with the period covered.
• Line 2: approved extras, each described.
• Line 3: VAT at 20% where it applies.
• Not on the invoice: ad spend billed by the platform.

What does this look like in practice?

Global Bridge Labs (GBL) charges a fixed monthly fee on a rolling monthly basis, with paid media budget paid by the client directly to the platform. A pattern we see is confusion when a single invoice mixes fees, ad spend and extras, which makes the true cost of each hard to see.
