The toolkit has four parts that can be used together or separately. The FAQs explain the basics in plain language, including the difference between direct and shared management, how cascade funding works for SMEs, what co-financing means and how to register on the EU Funding & Tenders Portal to obtain a Participant Identification Code (PIC). The Dos and Don'ts Manual breaks the process into 12 stages, from getting the business "grant-ready" and deciding whether a call is worth the effort, through work planning and budgeting, to submission and the start of the project. It comes with ten templates, among them an opportunity scorecard, a KPI register, a budget table with narrative examples, a risk register and a pre-submission compliance checklist. The General Guidelines expand on each stage with practical advice, and the annexes add a completeness checklist and a Compendium of Best Practices.

The Compendium presents 20 organisations from across Europe and the routes they took to funding. They range from a one-person fly-fishing guide in the Irish Midlands supported by the Just Transition Fund, to a small Croatian travel agency that built up experience through a series of nationally managed schemes, to an Irish museum taking part in a Horizon Europe consortium. Not every story is a success: one solo founder whose proposal was rejected explains what she would do differently.

The toolkit also looks at why applications fail. It identifies 20 common mistakes, grouped into strategic, technical, organisational and financial ones, each with a question applicants can ask of their own draft. Among them are proposals that describe a good business idea without linking it to the objectives of the call, projects that use words like "green" or "digital" without concrete actions behind them, budgets that underestimate technical costs, and plans that leave no room for the administrative work or the cash-flow pressure that comes with co-financing and delayed payments. According to the analysis, applications fail far more often because of how the project is designed and presented than because the idea itself is weak.

The case studies share some common ground. Successful applicants chose calls that genuinely fit their needs, kept the scope in line with what their team could deliver, dealt with permits and legal requirements early, and made use of outside help from regional agencies, chambers, intermediaries or experienced advisers. For micro-enterprises, smaller and more targeted instruments, such as cascade calls run by EU-funded projects, often proved more worthwhile than large, complex programmes.
