Your team spends 20 minutes reviewing. We handle everything else.
Send us the document
Upload your RFP, security questionnaire, or vendor form in any format — PDF, Word, Excel, or a portal link.
We draft the complete response
We extract every question, match answers from your knowledge base, draft responses, and flag anything needing your input. Human review included.

The ROI is straightforward
One contract closes.
The service pays for itself.
A mid-market deal typically starts at $50k–$200k ARR. The time and risk of missing or mishandling a single RFP dwarfs the cost of having a dedicated team handle it right.
Typical in-house cost (per response)
40-80 hours of senior engineering at $150/hr blended
Proposal System One (Sales-led)
Up to 15 submissions, full service
Plus the deal you stop losing

Compared to alternatives
Below market for done-for-you. Near software-only pricing.
Most options leave you choosing between expensive software your engineers still have to operate, or per-RFP freelancers who disappear when the next deadline hits.
| Option | Real cost | What you get |
|---|---|---|
| Loopio (RFP software) | ~$1,898/mo $22,786/yr median | Software only. Your engineers still write every response. |
| Responsive / RFPIO | Quote-only Similar enterprise tier | Same — software, no humans included. |
| Freelance proposal writer | $1,875–$4,375 per single RFP | One-off. No continuity, no answer library, no QA process. |
| DFY agency per-RFP | $3,500–$7,500 per single RFP | Service. Per-document pricing, no library compounding. |
| Proposal System One us | $333–$3,000 per submission | Full DFY service + answer library that compounds. 24-hour turnaround. Flat per-submission pricing across a monthly cap. |
Per-submission math: Solo plan ($3,000/mo, 1-5 subs) = $600-$3,000 each. Sales-led ($5,000/mo, 6-15 subs) = $333-$833 each. Cheaper than any DFY freelance per-RFP rate, competitive with software-only platforms that don't include human work.
We cap intake at 8 new submissions per month — and we don't miss deadlines.
Most proposal services scale by hiring more junior writers and stretching the team thin. Quality drops. Deadlines slip. You get a polished-looking deliverable that gets your bid thrown out for a missing requirement.
We do the opposite. Hard cap on volume per month, every submission reviewed before delivery, and we turn slots away when the calendar fills. If you're submitting in the next 30 days and the slot is open, you're in.
Slots are claimed by intake order. Send your document below to lock yours.
Sample output · what you actually get
Question 47 of 152
Describe your encryption-at-rest controls for customer data, including key management, rotation cadence, and HSM usage.
Drafted response
All customer data is encrypted at rest using AES-256-GCM. Encryption keys are managed in AWS KMS with automatic annual rotation. Customer-managed keys (CMK) are available on Enterprise plans, with rotation policies set by the customer. Production database volumes use envelope encryption: data is encrypted with a per-table data key, which is itself encrypted with a CMK stored in HSM-backed KMS (FIPS 140-2 Level 3).
