Anything you cannot tie to one of those, or to a result you can inspect, is padding, and a monthly receipt shows it.
What does a B2B marketing agency retainer include? If you are a head of marketing looking at a proposal, it lists hours, a few deliverables and a monthly fee, and you cannot tell which lines will move your pipeline and which are there to fill the page.
This guide explains what a B2B retainer should include, how to spot padding, and how to choose between hours, deliverables and outcomes. It also gives you a monthly "retainer receipt" you can ask any agency for, including us. TBG Operations is a B2B marketing agency, so read our view with that in mind and check it against your own situation.
What is a B2B marketing agency retainer?
A retainer is an agreement to pay an agency a regular monthly amount for ongoing marketing work, instead of paying per project.
It suits work that never really finishes: publishing, social media, paid media, reporting and planning. You buy access to a team's time and skill each month. What you get depends on how the scope is written.
A project has a start, an end and a defined output, while a retainer has a rhythm and a review. Both can work, and the mistake is using one when you need the other.
What should a B2B retainer include?
A good retainer covers four things: strategy, execution, reporting and a link to your sales team.
- Strategy. A written plan for the quarter, with the audience, the goal, the channels and what will not be done. It is reviewed each month and changed when the data says so.
- Execution. The actual work: articles, posts, ads, emails, design or video. Each item has an owner, a due date and an approval step.
- Reporting. A short monthly report on what was done and what happened. It should name the metric that matters to you, such as qualified enquiries, and not stop at impressions.
- Link to sales. A regular conversation with whoever follows up the leads, so marketing learns which enquiries were good and which were not.
The fourth item is the one most proposals leave out. Without it, an agency can deliver everything on the list and still not help you sell.
What counts as padding in a retainer?
Padding is any line in the scope that you cannot connect to a deliverable, a decision or a result you can inspect.
These are the ones we would question first:
- Vague hours. "Account management: 10 hours" with no list of what those hours produce.
- Meetings as output. A weekly call that has no agenda, no decisions and no notes.
- Reports that only count activity. Posts published, emails sent, impressions earned, with no link to enquiries or pipeline.
- Unlimited revisions or "strategy" with no document. If a strategy exists, it can be shared as a page.
- Tool or platform fees added without saying what you get that you could not buy yourself.
- Duplicate work. Content that is rewritten for four channels with no change in message, so volume looks high and value stays low.
In our view, a quick test works well. For every line, ask: what will I be able to see or use at the end of the month that I could not before? If the answer is "nothing", it is padding.
Should a retainer be priced by hours, deliverables or outcomes?
Each model fits a different kind of work, and each can hide padding in a different place.
| Model | Works well when | Where padding hides | What to ask |
|---|---|---|---|
| Hours | The work is hard to define in advance, such as advisory or ongoing optimisation | Hours billed for time spent, not for what was produced | A monthly log of hours by task |
| Deliverables | The output is clear, such as four articles or a set of ads | Easy items fill the list while hard, useful work is left out | The brief, the standard and the approval steps for each item |
| Outcomes | You can measure a result the agency can influence | Targets set so low they are met without effort, or metrics the agency does not control | How the number is measured, and who controls the inputs |
Many retainers mix the models. That is fine, as long as each line says which model applies to it.
What drives the scope and cost of a retainer?
Scope and cost follow the same few drivers. We are not giving figures here, because they differ too much between agencies and markets to be useful.
- Number of channels. Each channel needs its own planning, production and reporting.
- Volume and frequency. Weekly publishing needs a different team from monthly publishing.
- Depth of the work. A technical brief that needs an interview with an engineer takes more time than a general news post.
- Seniority of the people. Strategy time costs more than production time.
- Approvals. A long approval chain on your side slows delivery and increases the effort of managing it.
- Reporting and meetings. More stakeholders means more reports.
When you compare two proposals, compare these drivers first. Two quotes that look similar in price often cover very different amounts of work.
Who actually does the work on a retainer?
Ask for names and roles before you sign. Many proposals show a senior team in the pitch and hand the work to someone else.
You do not need to know every person. You do need to know who writes, who designs, who runs the ads, who checks the work, and who you speak to when something goes wrong.
Ask whether any work is done by freelancers or partners, and whether your information is shared with them. If your company works under confidentiality rules, this matters.
At TBG, every engagement runs under an NDA, signed before any internal material is shared. That is how we work, and you can ask any agency for the same.
What does a typical month look like?
This is an illustrative example, not a client case. It shows how a month can be laid out for a B2B services firm that has one marketing manager and wants steady content and one paid channel.
| Week | Work | What you can inspect at the end |
|---|---|---|
| 1 | Review last month's results with you and sales. Agree priorities. Interview an internal expert. | A one-page plan and interview notes |
| 2 | Draft two articles and four LinkedIn posts from the interview. Set up ad variants. | Drafts for your approval |
| 3 | Revisions, publishing, ads go live. | Published links and live ads |
| 4 | Collect results. Ask sales which enquiries were good. Write the report. | A one-page report and next month's plan |
Notice that every week ends with something you can open. That is the standard to hold any retainer to.

How do you review a retainer each month?
Ask the agency for a retainer receipt: one page, sent every month, that shows what you paid for and what you received. You can copy this table and use it with any agency.
| Line | What it should show |
|---|---|
| Scope this month | The items planned, with owner and due date |
| Delivered | The items completed, with links or files |
| Not delivered | Items that slipped, and why |
| Hours or effort | By task, if hours are part of the scope |
| Result | The metric you agreed, with last month beside it |
| Sales feedback | Which enquiries were good and which were not |
| Next month | What will change because of this month |
If an agency cannot produce this page, it is worth asking why. If it can, you have an easy way to see padding before it builds up.
Review it for ten minutes at the same time each month. Pay most attention to the "Not delivered" and "Sales feedback" lines, because those are where problems appear first.
When is a retainer the wrong choice?
A retainer is usually the wrong choice when the work has a clear end or when you do not yet know what you need.
- A one-off deliverable, such as a website rebuild or a single brand film, fits a project.
- An unclear problem. If you cannot say what is broken, a short diagnosis comes before a monthly commitment.
- No internal owner. Someone on your side must brief, approve and give feedback. Without that, a retainer drifts.
- A long minimum term that you cannot leave if results are poor.
Check the exit terms before you start. TBG works month to month with no minimum term, and work product is transferred to the client. Ask every agency you speak to the same questions.
What are the 7 P's of B2B marketing?
The 7 P's are product, price, place, promotion, people, process and physical evidence. This is the extended marketing mix, as set out by the Chartered Institute of Marketing (CIM).
The first four are the original marketing mix. People, process and physical evidence were added for services, where how the work is delivered is part of what the customer buys.
The list is useful when you review a retainer. Ask which of the seven the agency is changing, and how you will know it worked.
What should you check in India, the UK and the Netherlands?
Treat these as questions to put to any agency and to your own legal or finance team. We are not giving legal advice.
- Contract terms. Which country's law applies, how disputes are handled, and how you can end the agreement.
- Tax. Whether GST, VAT or withholding applies to the invoices, and who handles the paperwork.
- Time-zone coverage. Which hours the team is reachable in, and how urgent requests are handled.
- Data and tracking. Where your data is stored and which privacy and cookie rules apply to the campaigns.
The answers affect how easy a retainer is to run, and are worth settling before the first invoice.
What should you ask before you sign a retainer?
Use these questions in the final call:
- What exactly will I receive each month, and in what form?
- Who does the work, and who checks it?
- How do you report, and which metric do you tie it to?
- What happens if results are poor after a quarter?
- How do I end the agreement, and what do I keep?
- Is my information used for anyone else, or to train any model?
- Which parts of the scope would you drop if my budget were smaller?
The last question is a good test. An agency that has padded its scope will find it hard to answer.
