The Problem
Responding to complex government and enterprise RFPs is chaotic. Proposal teams juggle hundred-page tender packs, scattered spreadsheets, unverified past answers, and unforgiving submission deadlines.
Before
- •Scattered Proposal Files: Tender documents, client updates, and answers lived in separate email threads.
- •Unverified Content Reuse: Writers copied outdated technical specs and pricing sheets from previous bids.
- •Risk of Missed Deadlines: Teams had no central schedule for clarification questions, reviews, or sign-offs.
Goals
- •Central Proposal Workspace: Manage every tender from initial qualification to final submission in one place.
- •Verified Knowledge Library: Give writers instant access to approved technical answers and compliance assets.
- •Clear Milestone Tracking: Track every tender deadline, compliance task, and team assignment with countdowns.
Requirements
Interviews with executive leadership, proposal managers, and developers shaped core requirements:
Executive Leadership
Pipeline Visibility & Win Rates
"Which bids are in progress, what is our win rate, and where are team bottlenecks?"
Pipeline summary tracking active tenders, win rates, and upcoming milestone dates.
Bid Managers & Writers
RFP Breakdown & Proposal Drafting
"Who owns section 4.2, where are the approved technical answers, and when is sign-off?"
Requirement checklist boards, task assignments, and a searchable knowledge library.
Operations & Developers
Data Security & Access Control
"How do we store proprietary pricing models and proposal files securely in real time?"
Supabase database, role-based access control, and fast Next.js server actions.
Design & Development Process
A focused 4-month build from proposal workflow audits to a working full-stack platform:
Audit & Requirements
Mapped how proposal teams parse tender packages, assign sections, and review drafts.
Screen Structure
Organized workflows into 7 dedicated views for pipeline, tasks, calendar, knowledge, and reports.
UI Design
Designed dense requirement tables, Kanban boards, and deadline countdowns in Figma.
Full-Stack Build
Built the complete platform with Next.js, Supabase PostgreSQL, and server search.
Command Center
Overview tracking active proposals, upcoming submission deadlines, and team tasks.
Tenders Pipeline
Visual stage tracking for bids from qualification and drafting to review and submission.
Requirements & Tasks
Breaks down proposal requirements into checklist tasks with assigned section owners.
Key Decisions
Simple interface choices directly informed by proposal team needs:
Visual Tender Stages
Teams used email chains, making it hard to see if a proposal was on schedule or stalled.
A visual pipeline moving bids from qualification through drafting, review, and submission.
Compliance Task Matrix
Complex RFPs have hundreds of mandatory clauses that are easily overlooked in long PDFs.
An interactive task matrix linking each RFP requirement directly to a section owner and status.
Verified Knowledge Library
Writers wasted days asking colleagues for company credentials, certifications, and past answers.
A searchable library of approved answers, team bios, and case studies ready for instant reuse.
Procurement Calendar
Client question deadlines and document updates were frequently missed across active proposals.
A dedicated procurement calendar highlighting upcoming client cutoff dates with live countdowns.
Procurement Calendar
Calendar view highlighting client question cutoffs, submission milestones, and team review checkpoints.
Knowledge Library
Searchable database of approved company credentials, past project narratives, and technical responses.
Tech Stack
A clean, modern setup built for fast loading and responsive filtering:
Data Sources
Ingests tender specifications, document updates, and compliance files.
Database
Stores proposal pipelines, knowledge base records, and team permissions in Supabase.
Server Logic
Handles search indexing, task transitions, and deadline alerts on demand.
User Interface
Clean interface with interactive task boards, dark mode, and calendar views.
Results & Impact
The platform transformed how proposal teams collaborate, track requirements, and win bids:
Design System & Tokens
Built a reusable Figma component system for data tables, stage tags, and status badges.
Centralized Supabase Hub
Connected proposal pipelines, tasks, and document records into a single Supabase backend.
Standardized Knowledge Base
