A capability statement is the one document every federal buyer expects to exist, and the one most businesses either skip or over write. It is a single page that answers, fast, whether you are worth a second conversation. Buyers scan it in seconds, not minutes, so everything about writing one well is really about restraint.
1 · Keep it to one page
This is the one rule that is not negotiable. A buyer deciding whether to keep reading is not going to turn to page two. If it does not fit on one page, the problem is usually not length, it is that you have not decided what actually matters yet.
2 · Lead with core competencies
Open with a short, specific list of what you do, in language a buyer would recognize, not internal jargon or a mission statement. Three to five lines is usually enough. This is the section most buyers actually read, so it earns the top of the page.
3 · Name your differentiators plainly
Say what makes you different from the next company with the same NAICS code: a certification, a specific piece of equipment, a niche capability, a location advantage. Vague claims like "quality service" and "customer focused" say nothing a buyer can use. Specific claims do the work instead.
4 · Show past performance, even if it is small
List contracts you have delivered, government or commercial, with enough detail to be credible: who the client was, what you did, roughly when. If you are early and have little to show, list what you have honestly rather than leaving the section blank. See past performance when you have none for how to build this out.
5 · Put your company data where it is easy to find
UEI, CAGE code, NAICS codes, certifications, and a contact who actually answers, usually as a sidebar or a footer block. A buyer who wants to move forward needs these facts immediately, not buried in paragraph text.
6 · Keep a current PDF ready to send
Update the document the moment a fact on it changes, save it as a plain PDF, and keep it somewhere you can attach in under a minute. A capability statement that is a week out of date at the moment someone actually asks for it defeats the purpose of having one ready at all.
This document stays entirely yours to write. Quarry does not generate it, but the same plain, specific language that makes a capability statement work is what makes your Quarry profile useful too, since both are really just you describing your business clearly to someone deciding fast.
