Most agencies still spend days building estimates manually.
They open Excel, copy old tasks, guess time ranges, argue about scope, and send the file to five people for review.
By the time the client gets a response, someone else has already won the deal.
What if you could generate a complete, structured, and client-ready estimate in under one hour?
This guide shows exactly how, using smart assumptions, reusable templates, and AI-powered estimation inside devtimate.

Why Speed Matters in Estimation
Clients do not only compare prices. They compare response time and clarity.
The faster you reply with a clear estimate:
- the more professional you look,
- the stronger your position in negotiations,
- and the higher your win rate.
Internal data from early devtimate users shows that sending estimates the same day increases close rates by 40–60%.
It is not about cutting corners; it is about cutting the waiting.
The One-Hour Estimation Workflow
1. Upload your client’s materials
Start with whatever the client provided RFP, SRS, feature list, or even a meeting transcript.
devtimate’s AI analyzes the document, extracts the requirements, and instantly builds a structured draft with modules, tasks, and time ranges per role.
You can refine or reorganize everything in seconds through the built-in AI Assistant.
2. Use your templates and library
Repetitive work kills productivity.
With reusable templates and a module library (for example authentication, payments, admin panels), you can drop ready sections into any estimate with one click.
Each task retains your predefined roles, rates, and time ranges, keeping estimates consistent across the team.
3. Define assumptions upfront
Every fast estimate relies on explicit assumptions.
Add a short “Assumptions” block at the end of your estimate. Example:
| Area | Default assumption |
|---|---|
| SSO | Google, Facebook, and Apple integrations |
| Admin panel | CRUD for users, companies, and roles |
| Integrations | Documented APIs with limited endpoints |
| Payment | Stripe or Braintree with basic subscription model |
Writing these out saves hours of clarification later and keeps everyone aligned.
4. Apply time ranges instead of single numbers
Instead of locking yourself into “5 days”, use ranges (for example 4–6 days).
Ranges communicate realism and flexibility, and clients appreciate that.
If the scope is vague, widen the range (±30%).
After discovery, narrow it (±10%).
From Estimate to Proposal
Once your estimate is ready, transform it into a polished proposal with devtimate’s Proposal Creator.
Company branding, cost summaries, and total hours are filled automatically.
No copy-pasting, no spreadsheets just review and send.
This means:
- same-day responses,
- consistent visual quality,
- and a clear breakdown clients can actually understand.
Assumptions That Save You Hours
1. Work with predefined defaults
Use default modules for common scenarios such as authentication, payments, notifications, and dashboards.
They already contain role-based effort and technical scope, so you do not start from zero.
2. Document what is out of scope
Quickly list what is not included.
It helps protect you from scope creep and clarifies future change requests.
3. Capture client questions early
Your AI assistant can even generate a short list of “questions the client might ask” based on your estimate.
Having those ready lets you stay one step ahead in calls or demos.
Risk Buffer and Time Ranges
No matter how clear the brief looks, risk is always there.
Add a time buffer for modules with higher uncertainty (integrations, APIs, performance, or external dependencies).
Example:
- Simple API connection: +10%
- Complex integration without docs: +30%
- Third-party verification (for example app store or Spotify): +20–40%
These micro-buffers are what make a one-hour estimate realistic because you think fast and smart.
Make It Readable for Non-Technical Clients
The best estimates are written in client language, not developer shorthand.
| Developer says | Client understands |
|---|---|
| “Auth module with OAuth2 flow” | “Sign-in and registration with Google or Facebook” |
| “Stripe webhooks” | “Automatic payment confirmation after checkout” |
| “User CRUD” | “Manage users in admin panel” |
Translate technical terms into business outcomes.
It builds trust and speeds up approvals.
Quick Checklist
✅ Upload client docs to AI estimator
✅ Add templates and library modules
✅ Define assumptions and ranges
✅ Add risk buffer per module
✅ Translate tech to client language
✅ Export proposal and send same day
FAQ
1. How accurate can a one-hour estimate be?
Very accurate if you use structured templates, define assumptions, and let AI handle repetitive work. The human step is validation, not manual typing.
2. Should I include a discovery phase if I estimate fast?
Yes. Use the estimate to sell a short paid discovery workshop where details are finalized. Fast does not mean shallow.
3. What is a good length for a modern estimate?
Between three and five grouped sections (modules), each with a few clear tasks, roles, and time ranges. Clients prefer clarity over volume.
4. How often should I update my templates?
Review them quarterly, add new modules, adjust hours based on experience, and refine pricing logic.
