Fixed price vs retainer marketing: which is better?

Know the number before you start.

Fixed price vs retainer marketing is a choice between paying a set price for defined work and paying a regular monthly fee for ongoing work. Fixed prices suit projects with a clear end, such as a website; retainers suit work that never really stops, such as ads or SEO, as long as you know exactly what the fee covers.

What is fixed price marketing?

You agree a set price for a defined piece of work, such as a website, a brand identity or an ads set-up. The price doesn't change if it takes the agency longer than planned.

It works because both sides agree the scope up front. Changes to that scope are priced separately.

What is a marketing retainer?

You pay a regular fee, usually monthly, for ongoing work. That might be running ads, SEO, content, PR or a fractional CMO.

A good retainer says what's included each month, how results are reported and how either side can end it. A vague one is a monthly invoice and a hope.

Fixed price vs retainer marketing: what are the pros and cons?

Neither is better in general. Each fits a different kind of work.

  • Fixed price, pros: you know the cost up front, the agency carries the risk of overrunning, and it's easy to compare quotes.
  • Fixed price, cons: needs a clear scope, and changes cost extra.
  • Retainer, pros: steady attention on work that never stops, room to adapt the plan, and a team that knows your business.
  • Retainer, cons: harder to see what you're getting each month, and easy to keep paying for something that's stopped working.
  • Hourly, pros and cons: flexible for small, unpredictable jobs, but hard to budget and it rewards slow work.

Which model suits which work?

Match the model to the shape of the job.

  • Fixed price: websites, rebrands, audits, campaign set-ups, launches and one-off videos.
  • Retainer: Google Ads and paid social management, SEO, AI SEO, PR, content and fractional CMO work.
  • Either: website care and hosting, which some agencies price as a fixed monthly plan.

How do you choose between fixed price and retainer, step by step?

Use these steps on any quote, from any agency.

  1. Decide whether the work has a clear end. If it does, ask for a fixed price.
  2. If it's ongoing, ask what's included every month, in plain words.
  3. Ask how results will be reported, and how often.
  4. Ask what happens if you need more, or less, in a given month.
  5. Check the notice period and minimum term before you sign.
  6. Check who owns the work, accounts and data if you leave.
  7. Get the price and scope in writing before anyone starts.

What should a good retainer include?

A clear list of the work each month, named people doing it, a report you can read in five minutes and a fair way out.

If you can't tell what last month's fee paid for, ask. A good agency will show you.

How does Foundry price its work?

We agree a fixed price before we start, whether the work is a project or ongoing. After a short call, we send a written plan that says what's included, so there are no surprise invoices.

For ongoing work such as Google Ads, we update campaigns twice a month and report on the 1st, so you can see what the month delivered. Websites take 5 days from kick-off to live on average.

Fixed price and retainer FAQs

  • Only for ongoing work. For a project with a clear end, a fixed price is usually clearer and easier to compare.

  • Yes. Many retainers are a fixed monthly fee for an agreed scope. That's different from billing by the hour each month.

  • Small changes within the agreed scope are covered. New work outside it should be priced and agreed before it starts.

  • Long enough to give the work a fair test, with a clear notice period so you can leave if it isn't working.

  • We price ongoing work, such as ads and SEO, as well as projects. Either way, we agree the price before we start and send a written plan after a short call.

  • It ties the fee to account size. It can be fair for large accounts, but a fixed fee means the agency has no reason to push spend up.
