How Long Does It Really Take to Write a Winning Proposal?

Writing a winning proposal usually takes 10 to 40+ hours of focused work spread across 2 to 3 weeks, depending on the bid's size and complexity. A short, single-volume RFP runs about 10 to 20 hours. A multi-section bid takes 20 to 30 hours. A complex or federal proposal needs 31 hours or more.

If you've ever faced a deadline wondering how long it takes to write a proposal, you're asking the right question. A request for proposal (RFP) is a document a buyer uses to solicit competitive bids from vendors, and proposal writing time varies widely with the bid in front of you.

This guide breaks down RFP response time by bid size and type, maps where the hours go across each phase, and explains why a proposal runs long or short. The Bid Lab has been writing bids since 2017 and has submitted 1,000+ of them, so these ranges reflect real work - backed by independent benchmarks so you can pressure-test your own timeline.

How Long Does It Take to Write a Proposal, by Bid Size?

Proposal writing time scales with the bid. The Bid Lab groups engagements into three tiers, and the hours climb with page count, number of requirements, and how many stakeholders weigh in.

For comparison, firms spend about 23 hours writing the average RFP response and involve 9 people, according to benchmark data published by MarketingProfs. Over half of teams report 5 to 20 hours per response, roughly a third report 21 to 50, and fewer than 10% top 50 hours - so the tiers above track the industry norm.

Those calendar windows aren't arbitrary. Under Federal Acquisition Regulation (FAR) 5.203, federal agencies must generally allow at least a 30-day response time from the date a solicitation is issued for non-commercial actions expected to exceed the simplified acquisition threshold - and at least 45 days for research and development. State and local bids, by contrast, can close in as little as two weeks.

How Does the Type of Bid Change the Timeline?

Beyond size, the type of buyer shapes your hours. Government bids demand strict compliance and formatting, commercial bids move faster but hinge on customization, and grants lean heavily on narrative and budget justification.

• Government and public sector. Rigid compliance, mandatory forms, and portal submission add review and formatting time - see our guide to government contracting for what that entails.
• Commercial and private. Fewer forms, but more weight on tailored value and pricing strategy.
• Grants. Heavy narrative and budget justification, often with strict eligibility rules to confirm first - the writing differences between grants and RFPs are significant enough to change your whole approach.

Where Does the Time Go, Phase by Phase?

Most of the hours go into drafting, not searching. The Bid Lab runs every proposal through four phases - find, qualify, respond, and win - and each claims a predictable slice of the timeline.

A compliance matrix is a checklist that maps every RFP requirement to where you answer it, so nothing slips through. Past performance is your documented record of similar projects - and reusing well-organized past-performance content is one of the biggest time-savers there is.

Why Does a Proposal Run Long or Short?

The same-size bid can take twice as long depending on a handful of factors. Time balloons when information is missing or requirements are messy, and it shrinks when you have reusable content and clear direction.

A proposal runs long when:

• The RFP is ambiguous or poorly written, so you spend hours interpreting it.
• Inputs arrive late from subject-matter experts (SMEs) - the specialists who supply technical or pricing detail.
• Page limits are tight, because cutting to fit takes longer than writing.
• Many stakeholders and approval rounds slow every decision.
• Addenda change the scope mid-draft and force rework.

A proposal runs short when:

• You have a strong content library of reusable, up-to-date answers.
• Requirements are clear and well-structured from the start.
• A single decision-maker keeps approvals fast.
• You've won a similar bid before and can adapt it.
• You make the go/no-go call early and don't waste time on a long shot.

How Much of That Time Is Actually Writing?

Less than you'd expect. Writing the answers is only part of the job - qualifying, reviewing, formatting, and coordinating eat a large share too.

Benchmark data published by MarketingProfs shows wide variation: over half of teams spend 5 to 20 hours per response, while about a third spend 21 to 50. It's no surprise that most proposal professionals work more than 40 hours a week, with 14% regularly topping 50, according to the APMP U.S. Bid & Proposal Industry Benchmark.

"The clock doesn't start when you open a blank page - it starts the moment the RFP drops. The teams that win are the ones who've done the qualifying and organizing before drafting even begins," says Clarise Escobar, Writer at The Bid Lab.

How Can You Write a Winning Proposal Faster?

To shorten your timeline without cutting quality, tighten the phases you control before drafting starts. These five moves save the most time:

1. Decide go/no-go early. Qualify the bid fast so you don't sink hours into one you can't win.
2. Build the compliance matrix first. Map every requirement before you write a word.
3. Keep a content library. Reuse and refresh past-performance and boilerplate answers.
4. Start pricing early. Pricing approvals are a common bottleneck.
5. Schedule your reviews. Book the two-sets-of-eyes review and proofread before you need it.
