The Problem: Freelancers Losing Money to Contract Chaos
After interviewing dozens of freelancers and small agencies, I discovered a disturbing pattern: most were losing 10-20 hours per project and thousands of dollars annually to preventable contract issues. They desperately needed a contract management SaaS to streamline their workflow, but existing solutions were either too expensive, too complex, or designed for enterprises rather than service businesses.
Here’s what was happening:
Contract Creation Takes Forever
Freelancers reported spending 2-5 hours per project just drafting contracts. They were starting from scratch or copy-pasting old documents, manually updating client names, project details, and pricing, reformatting in Word or Google Docs, creating PDFs and emailing back and forth, and tracking which version was “final.”
The generic templates they found didn’t fit service businesses well—they were designed for product sales, not custom project work.
Scope Creep Kills Profitability
Without clear, structured project requirements, clients requested “just one more feature” repeatedly. Freelancers couldn’t reference what was originally agreed upon, disputes arose about what was included in the original scope, and projects ballooned to 2x or 3x the original estimate.
Freelancers faced an impossible choice: work for free to maintain the relationship, or damage the relationship by pushing back without documentation.
Getting Signatures Is Like Pulling Teeth
Traditional signature processes created friction: email PDFs, print, sign, scan, email back (taking days). Third-party signature tools cost $20-40/month per user. Clients lost PDFs and needed them resent. There was no way to track whether clients actually opened documents, and multiple signatories required coordinating separate email chains.
Invoicing Disconnected from Contracts
After contracts were signed, freelancers manually recreated pricing information in separate invoicing software. Payment milestones weren’t clearly linked to deliverables. Clients disputed invoices because they didn’t match contract terms. There was no systematic way to track payment against project progress.
No Central Source of Truth
Projects required coordinating contracts (in one tool), project requirements (in another tool), invoices (in yet another tool), client communication (email), and payment tracking (spreadsheets).
This fragmentation led to version confusion, lost information when tools changed, difficulty onboarding team members, and inability to analyze business metrics.
Freelancers needed an integrated platform that handled the entire client engagement lifecycle—from contract creation through project scoping, approval, signing, and invoicing—in one cohesive system.
The Solution: A Comprehensive Contract Management SaaS Platform
I designed and built SolydScope—a production-ready contract management SaaS that unifies contract creation, project scoping, digital signatures, and invoicing into a seamless workflow designed specifically for service businesses. This platform addresses every pain point in the traditional contract workflow while remaining affordable and accessible to freelancers and agencies.
What Makes This Contract Management SaaS Special
Intelligent Contract Management System
The system provides pre-built contract templates for common service types (web development, design, consulting, marketing) plus the ability to create custom templates with rich text editing, dynamic placeholders for client names, project details, and pricing, and automatic replacement when creating contracts from templates.
Contract versioning tracks every change automatically—view all previous versions, compare changes between versions, revert to earlier versions if needed, and track who created each version and when. Contracts move through clear lifecycle states (Draft, Pending Review, Approved, Signed, Archived) with status-based permissions preventing edits to signed contracts.
The system supports multiple contracts per project (NDA, Service Agreement, Amendment) and includes contract locking to prevent unauthorized edits.
Advanced Project & Requirements Management
This is the feature that prevents scope creep. Projects contain features, features contain sub-features, with unlimited nesting for complex requirements. The interactive requirement builder includes drag-and-drop feature ordering, visual hierarchy with expand and collapse, inline editing of descriptions, and real-time collaboration capabilities.
Three pricing models serve different needs: flat rate for fixed project budgets, per-feature pricing so clients see exactly what they’re paying for, and hourly billing with feature-level hour estimates. Progress tracking shows completion percentage at all levels, visual progress indicators, status tracking (Not Started, In Progress, Completed), and priority levels to organize features by importance.
An approval workflow moves requirements through Pending, For Review, and Approved states with complete timestamp tracking.
Digital Signature System
Professional signature workflow without monthly DocuSign fees. Create signatory profiles at the account level (CEO, Legal, Project Manager), upload signature images, reuse signatories across multiple contracts, and customize which signatories sign each contract.
The system supports signing order for multiple signatories, separate client signing flow requiring no account creation, and secure unique signing links per party. Digital signature capture uses an HTML5 canvas that’s touch-friendly for tablets, with clear and re-sign capabilities.
Every signature is tamper-proof with recorded signature data, signing timestamp, IP address logging, user agent information storage, and links to specific contract versions. Progress tracking shows visual indicators of signing progress, notifications when all parties sign, and automatic contract status updates.
Quotation & Proposal System
Professional client-facing proposals auto-generate from projects, convert project requirements into professional quotations, track quotation versions as requirements evolve, support regeneration when pricing changes, and export to PDF for client distribution with branded templates.
Invoicing & Payment Milestones
Connect contracts to revenue through payment milestones tied to project deliverables, percentage-based or fixed-amount milestones, reorderable milestones with drag-and-drop, and status tracking (Pending, Paid, Overdue).
Invoice generation is automatic from milestones, with professional templates including company logo and branding, customizable invoice numbering, bank details and payment instructions, configurable payment terms, and tax information. Per-user invoice configuration allows default payment terms, bank account details, tax registration numbers, and company information.
Multi-Business Support
For freelancers with multiple brands or agencies with sub-brands, create multiple business entities under one account. Each business has its own legal name, logo, address and contact details, tax identification numbers, and bank details. Choose a default business for new projects, and all documents (contracts, invoices, quotations) tie to specific businesses with professional branding for each.
Client Management & Portal
A centralized client database with relationship tracking feeds a dedicated client portal providing secure authenticated access. Clients view their projects and contracts only, collaborate on projects with threaded discussions through a comment system, and access everything securely with password-based authentication.
Secure Sharing & Collaboration
Share contracts and projects with non-users through token-based public sharing requiring no login. Link management allows toggling links on and off without regenerating, disabling compromised links, and setting expiration dates. Shared links are view-only by default and work with contracts, projects, and quotations.
Subscription Billing & Monetization
Complete SaaS business infrastructure with subscription tiers: Free (limited projects and contracts), Starter (small freelancers with unlimited contracts, 10 projects), Professional (growing freelancers with unlimited everything, priority support), and Agency (teams with multi-user, white-label, API access).
Payment processing integration via LemonSqueezy handles subscription events, customer lifecycle management (trial, active, cancelled, expired), transaction history tracking, and subscription management interface with upgrade and downgrade flows, billing history, invoice downloads, and payment method updates. Usage-based limitations enforce tier limits on projects, contracts, and clients.
Notifications & Communication
Keep users informed with in-app notifications (notification center with unread badges, mark as read and unread, mark all as read, and notifications for contracts signed, payments received, client comments) and email notifications (welcome emails, signature requests, payment reminders, system announcements).
How I Built This Contract Management SaaS
Building a production-grade contract management SaaS required solving complex technical challenges that go far beyond simple CRUD operations.
Modern Frontend Without Losing Backend Power
I wanted a React-level user experience but server-side efficiency. The solution combines server-side routing with React components for UI through Inertia.js, eliminating the need for a separate API while controllers return props directly to React components. This provides server-side rendering support for SEO and performance with type-safe routes throughout.
Type Safety Across Full Stack
The JavaScript and backend boundary typically loses type information, causing runtime errors. I solved this with TypeScript for all React code, auto-generated TypeScript route definitions, type-safe form handling with validation, and shared types between frontend and backend.
Real-Time Collaboration
Multiple users editing projects simultaneously could cause data loss. Optimistic UI updates with conflict detection, reactive components, efficient partial reloads, version tracking to detect concurrent edits, and user-friendly conflict resolution keep everything synchronized.
Secure Document Signing
Digital signatures must be legally defensible with tamper-proof audit trails. Contract version locking ties signatures to specific versions. Unique signing tokens per signatory can’t be guessed. Complete audit trails capture IP, timestamp, user agent, and signature data. Signature data is stored separately from contracts with version hash validation.
Multi-Tenant Data Isolation
Different users must never see each other’s contracts or clients. Row-level security with policy-based authorization ensures all models are scoped to authenticated users. Access policies enforce ownership, database constraints prevent orphaned records, permissions handle role-based access within accounts, and a separate client portal provides isolated permissions. Following OWASP security best practices was crucial for protecting sensitive contract data.
The Impact
For Freelancers
Time savings transformed project economics. Contract creation dropped from 2-5 hours to 15 minutes (90% reduction). Scope documentation moved from ad-hoc spreadsheets to a structured requirement builder. Signature collection went from 3-7 days to same day (often within hours). Invoice generation became one-click automation instead of manual recreation.
For Agencies
Consistency and professionalism improved through standardized contract templates across all team members, professional branded quotations and invoices, a client portal providing 24/7 access to project information, and multi-business support for parent companies and sub-brands.
For Clients
Clarity and convenience enhanced experience with clear breakdowns of features and pricing (no surprises), frictionless signing (no printing or scanning), self-service portal for project status, and professional documentation building trust.
Business Metrics
SolydScope enabled capabilities previously requiring enterprise tools: complete audit trails for compliance, usage analytics (most common features, pricing trends), client lifetime value tracking, and revenue forecasting based on payment milestones.
Technical Challenges in Building a Contract Management SaaS
Contract Versioning Complexity
Contracts evolve through negotiations. Supporting version history while maintaining signature integrity required immutable version records, signatures tied to specific versions, automatic versioning on edits, and user-friendly version comparison.
Signature Workflow UX
Digital signatures needed to be easier than printing and scanning while remaining legally sound. The solution provides zero-friction client experience (no account needed), touch-friendly signature pad, clear progress indication, email notifications at each step, and mobile-responsive signing interface.
Dynamic Pricing Calculations
Three pricing models with nested features created calculation complexity. Flat rate needs simple override capability. Per-feature sums features and sub-features recursively. Hourly aggregates hours across the feature tree times the rate. Real-time updates occur as requirements change.
Multi-Tenant Security
SaaS applications must guarantee data isolation. Global query scopes ensure user ownership checks. Policy-based authorization applies to every action. Database constraints prevent orphaned records. Separate client authentication provides an isolated realm.
PDF Generation Consistency
Generated PDFs needed to look professional across different contract lengths and content. Responsive HTML templates, proper page break handling, header and footer on every page, logo and branding integration, and font embedding ensure consistent rendering. The solution uses DomPDF for reliable server-side PDF generation.
What’s Next
SolydScope is production-ready with a roadmap for continuous enhancement.
Future phases include team collaboration (multi-user workspaces, internal comments and mentions, task assignment, approval workflows), advanced automation (email integration, automated reminder sequences, payment gateway integration, automated invoicing, client onboarding automation), AI-powered features (contract clause suggestions, auto-generate requirements from descriptions, price estimation based on similar projects, risk detection), and ecosystem expansion (public API, integration connectors, accounting software integration, CRM integration, white-label solution for agencies).
What I Learned
This project taught me that successful SaaS isn’t about having the most features—it’s about solving the entire problem. Freelancers don’t need just contract templates; they need the complete workflow from scoping to signing to invoicing.
The frontend and backend combination proved ideal for SaaS development—modern UI power with backend efficiency, without the complexity of maintaining separate codebases. Type safety caught dozens of bugs during development that would have become production issues.
Building subscription billing, usage limits, webhook handling, and customer lifecycle management is as complex as the core product features. Everything that might change needs versioning—contracts, quotations, pricing, project requirements. Users will need history.
Public links without authentication require careful thought about permissions, expiration, and revocation. Token-based security with audit trails is essential.
