Your best proof is the work you already did — if you can find it

Ask any small shop that bids on government or enterprise work where their last proposal stalled, and a surprising number will say the same thing: it wasn't the technical approach, it was the scramble to assemble past performance. The evaluator wants evidence you've done this before — relevant contracts, measurable outcomes, references who'll vouch for you — and the team spends the last frantic days of the deadline digging through old emails and pinging former clients who may or may not reply in time. The proof existed. It just wasn't anywhere you could reach it under pressure.

A past-performance library is the fix: a deliberate, maintained record of the work you've delivered, the results it produced, and the people who'll speak to it — captured as you go, so that the next proposal starts from a stocked shelf instead of a blank page. For teams chasing federal work, where past performance is often a scored evaluation factor and where you're frequently the partner who brings (or lacks) it, this isn't administrative tidiness. It's a competitive asset.

Why it has to be captured during delivery, not at bid time

The reason most teams don't have a past-performance library is timing: the moment you most need this information is the worst possible moment to gather it. At bid time you're under deadline, the project details have gone fuzzy, the metrics live in a dashboard nobody exported, and the client contact who loved you has moved on. Reconstructing proof after the fact is slow, lossy, and sometimes impossible.

Captured during delivery, it's nearly free. The win details are fresh, the outcome metrics are live, and the client is at peak goodwill — the same window that makes the post-sale relationship the right place to ask for a referral or a quarterly review. A team that records proof as it delivers builds an asset that compounds; a team that waits rebuilds it from scratch every bid and gets a weaker version each time.

What belongs in the library

A past-performance entry is more than "we did a project for them." To actually strengthen a proposal, each entry should carry the things an evaluator — or your own proposal writer — needs to make the case.

  • The scope and relevance. What you did, for whom, and at what size, described in terms that let you match it against a future requirement. Relevance is what evaluators score, so capture enough to argue it.
  • The measurable outcome. Numbers beat adjectives. "Cut their onboarding time 40%" or "delivered on a fixed-price SBIR Phase I on schedule" is proof; "client was happy" is not. This is the same evidence-over-vibes instinct that makes any metric persuasive.
  • A reference who'll vouch. A named contact who has agreed to be a reference, with their current details and the date you last confirmed they're still willing. A reference you can't reach is worse than none.
  • Reusable proof artifacts. The case study, the testimonial quote, the chart, the contract summary — the actual material a proposal can lift, so you're assembling rather than writing from zero.

Keep the references warm, not just listed

A list of references decays the moment you stop maintaining it. People change roles, leave companies, and forget the details that made them enthusiastic — and a reference call that catches your champion cold can do more harm than no reference at all. The library is only as strong as the relationships behind it.

That means the same relationship discipline you'd apply to an open deal applies to your past clients: stay in genuine contact, confirm periodically that they're still willing to be a reference, and keep their current role and details fresh. This is also where winning back and renewal work pays a second dividend — the client you stayed close to is the one who'll take the reference call and speak warmly, while the one you only contact when you need something will hesitate or go silent at exactly the wrong moment.

Make the library a view of your CRM, not a separate document

The trap is to build the past-performance library as a standalone spreadsheet or a folder of documents — which immediately starts drifting from the truth and, like most parallel systems, goes stale the same way data does without hygiene. The information you need is already in your CRM: the accounts you've delivered for, the contacts who'd vouch, the outcomes you tracked. The library should be a view of that, not a copy of it.

In Hitt CRM, every delivered account already lives as a contact and deal record with its history intact, so past performance becomes a matter of tagging and enriching what's there rather than maintaining a second database. Mark your reference contacts, capture the outcome and the reusable proof on the record while the win is fresh, and a segment or report can surface "everything relevant to this kind of pursuit" in seconds when a proposal is due. You can even set a recurring task to re-confirm each reference periodically, so the list stays warm instead of quietly rotting. When the next bid lands — and in GovCon and SBIR pursuits it will, often on a brutal clock — you open a stocked, current library instead of starting a scramble, and that head start is frequently the difference between a proposal you submit confidently and one you submit late and thin.

The one-sentence version

Your strongest proposal evidence is the work you've already delivered, but only if it's captured while the win is fresh and the references stay warm — so build the past-performance library as a maintained view of your CRM rather than a stale side document, recording the relevant scope, the measurable outcome, the reusable proof, and a confirmed reference on each delivered account, so the next bid starts from a stocked shelf instead of a deadline scramble.
