How to write a digital tender brief that gets strong bids

A vague brief attracts vague bids. If three agencies read your invitation to tender and each prices a different project, the fault is usually the brief rather than the agencies. A good digital marketing tender brief tells suppliers exactly what you want to achieve, what you are working with, and how you will decide, so the responses you get back are comparable, honestly priced, and worth your time to score.

Start with the outcome, not the output

Weak briefs ask for a list of activities: so many blog posts, so many links, so many hours. Strong briefs lead with the business outcome. Do you need more qualified enquiries, more online revenue, a lower cost per lead, or visibility in a new market? When the outcome is clear, a good agency can propose the right mix of work to reach it, and you can judge proposals on thinking rather than on who promised the most units.

Give agencies the numbers

Suppliers cannot price a project they cannot see. Share what you reasonably can: current traffic and revenue, your best and worst performing channels, conversion rates, and access to analytics if the process allows it. The more context you provide, the more accurate and honest the bids, and the easier it is to spot an agency that has actually read your data versus one that has pasted in a template.

Be clear on scope and budget

Define the boundaries. Which channels are in scope, which are out, and who owns what between your team and the agency. If there is a budget or a range, say so. Buyers often hide the budget hoping to get a bargain, but it usually just produces proposals aimed at the wrong scale, some far too thin to work and some far beyond what you can spend. A stated budget gets you proposals that fit.

Set fair evaluation criteria

Tell suppliers how you will score them and weight it toward what matters: evidenced results, the seniority of the people who will do the work, cultural fit, and price, in whatever balance suits you. Publishing the criteria keeps the process fair and pushes agencies to answer your questions rather than send a generic deck. If you want to see this done well, our tenders pages set out exactly how we respond to a specification.

Keep the timeline realistic

Give suppliers enough time to write a proper response, usually two to three weeks for anything substantial, and build in a window for clarification questions. A rushed deadline filters for agencies with a template ready, not the ones who would do the best work. Set the go-live date you actually need, then work back from it honestly. A clear, well-paced brief is the single biggest thing you can do to attract strong bids.
