Choose a B2B tech marketing agency by checking how its experience, delivery team and reporting match the part of your sales process that needs improvement. Ask for comparable client results, a clear plan for lead follow-up and evidence that the agency can work across your target markets.
Start with the business problem. You may need more demand from the right accounts, better qualification of existing leads, or support for partners who lack campaign capacity. Turn that need into a short brief before approaching agencies: outline your commercial objective, target accounts and markets, budget, sales cycle and current results. Include the content, campaign assets and relevant CRM information available, who follows up leads and where your team lacks capacity. This gives agencies a common starting point and makes their proposals easier to compare.
Key takeaways
Choose a B2B tech marketing agency with comparable client results and a measurement plan tied to your commercial objective.
Confirm who owns lead follow-up, qualification and reporting across your priority markets.
Match the agency's capabilities to your team's gaps, then use a shared checklist and a defined pilot to assess fit.
Seven criteria for evaluating a B2B tech marketing agency
1
Measure the commercial outcome you need
Agree what success means before comparing proposals. Depending on the programme, that could include target-account engagement, marketing-qualified leads, sales-qualified leads, accepted opportunities or pipeline contribution.
A marketing-qualified lead, or MQL, meets agreed marketing criteria. A sales-qualified lead, or SQL, meets agreed sales qualification criteria. Definitions vary, so ask each agency to state exactly what it will deliver and how sales will accept or reject it.
Request a sample report and ask how it connects campaign activity to the relevant sales stages. Reach and engagement remain useful diagnostic measures. Their value depends on how they support the agreed objective.
A promise of qualified leads needs the same scrutiny. If an agency guarantees a volume of leads or meetings, get the qualification criteria, validation process and delivery conditions in writing, including how rejected leads are handled. A lead guarantee does not guarantee sales: revenue also depends on buyer decisions, your offer and sales follow-up.
2
Check experience with comparable technology buyers
Look for evidence that the agency understands your product complexity, buying roles and route to market. Relevant experience could involve industrial software, enterprise SaaS, cloud services or another category with a similar evaluation process.
In Forrester's Buyers' Journey Survey, 2025, 73% of B2B purchases involved three or more departments. Ask how an agency adapted content for technical evaluators, finance and operational stakeholders in a comparable campaign, and request examples addressing their different priorities.
A comparable challenge and delivery method can be more informative than a familiar client logo alone.
3
Establish who follows up and qualifies leads
Confirm what happens after someone submits a form, attends a webinar or responds to outreach. Who contacts the lead, how quickly, and with what context? How are interested prospects handled when they are not ready for a sales conversation?
Ask for a documented handover, an example qualification record and a process for returning sales feedback to marketing. Qualification may include budget, authority, need and timing, commonly called BANT, adapted to the buying situation.
If your internal team lacks follow-up capacity, consider an agency with inside sales or end-to-end lead management. Where your team already handles this well, define how the agency will support that process.
4
Test local delivery in your priority markets
For international programmes, ask who adapts the targeting, offer and outreach for each market. Translation is one part of localisation; delivery also needs to reflect local terminology, buying conditions and communication preferences.
Request a relevant market example and meet the people responsible for execution. Confirm language capability, data handling responsibilities and the review process for regional messaging.
Evaluate the countries you actually plan to enter. A long list of supported markets is less useful than evidence of effective delivery in your priority territories.
5
Choose the right combination of capabilities
Match the agency's scope to your team's gaps. You might need a specialist for digital marketing, additional sales development capacity, or a coordinated programme covering both.
The difference between a B2B marketing agency and a lead generation agency is usually the scope of the work. A marketing agency can support positioning, demand creation and campaigns across the buying journey; a lead generation agency generally focuses on identifying and engaging prospects, sometimes including qualification or appointment setting. Services overlap, so compare the proposed deliverables and responsibilities rather than the label.
An integrated team can help when disconnected responsibilities are causing delays or lost leads. A specialist can be equally suitable when the rest of your process already works.
Ask who owns each handover between your team, the agency and any other suppliers. Request a delivery plan with named responsibilities and a clear route for resolving underperformance.
6
Confirm access to useful data and reporting
Ask what CRM, analytics and campaign data the agency needs, and what it can report with the access available. A capable partner should explain both the measurement plan and its limitations.
For example, an agency cannot reliably calculate cost per opportunity if opportunity outcomes are never returned by sales. Equally, the absence of direct CRM access should prompt an agreed reporting arrangement rather than an assumption that useful qualification is impossible.
Review a sample dashboard and ask how duplicate contacts, rejected leads and delayed opportunities are handled. Agree how attribution will be interpreted; it is an estimate of contribution rather than a complete record of every buying influence.
7
Assess channel expertise where partners drive growth
If distributors, resellers or technology partners are central to your business, ask for relevant channel marketing experience.
The agency should explain how it supports partner participation, campaign execution, lead follow-up and reporting to the vendor. Where Market Development Funds, or MDF, apply, clarify approval, evidence and reporting requirements before delivery begins.
Request an example showing what partners actually did and how activity progressed into qualified opportunities. Partner recruitment totals alone do not explain whether the programme produced commercial activity.
An example of the evidence to request
In our published industrial software campaign across Benelux and Scandinavia, the client needed greater regional visibility, qualified demand and progression into sales conversations.
The programme combined localised landing pages, search and competitor keyword campaigns, and ongoing analysis of visitor behaviour. Over 16 months, the published results included:
203
marketing-qualified leads, reaching 156% of target.
79
sales-qualified leads and 47 open opportunities.
€3.4 million
in projected pipeline value.
The pipeline figure represents potential opportunity value, rather than closed revenue. When reviewing any agency case study, check the timeframe, definitions and status of the reported outcomes. Ask which elements are relevant to your market and what would need to change.

Use a pilot to test working fit
A defined pilot can help you assess execution before expanding the relationship. Choose a scope that tests the main requirement, such as a campaign in one territory, a lead qualification programme or support for a selected partner group.
Agree the budget, responsibilities, deliverables and review points. Separate the outcomes the agency controls from those that also depend on sales capacity, the offer or market conditions.
In 6sense's 2025 Buyer Experience Report, the average B2B buying cycle was 10.1 months. Its global sample included nearly 4,000 buyers, with participation requiring a purchase of at least $25,000 in the previous two years. For a pilot supporting a longer buying journey, assess relevant account engagement, qualification quality and sales acceptance alongside opportunity results as they emerge. Set the review period around your sales process and the stage being tested.
Compare agency costs against the same scope. Fees depend on the services required, target markets, languages and delivery capacity. Ask for an itemised proposal separating agency fees from media spend, content or landing page production, data and sales development. Check which costs are one-off, which recur, and what assumptions about volume and duration underpin the quote.
Before signing, clarify data ownership, access to campaign assets and exit terms. Meet the delivery team and discuss a specific example of how they handled a campaign that missed its targets.
How Onboard supports the programme
At Onboard, our B2B marketing and sales services connect campaign execution with data, lead qualification and pipeline progression. Support can cover a specific delivery gap or a coordinated programme across markets.
The starting point is your commercial objective and the capacity already available in your team. From there, we agree the scope, qualification criteria and reporting needed to evaluate progress.
