VendorVault: Supplier Contract & Renewal Operations Hub

Problem and target customer

Why this exists

Customer problem

Renewal dates and compliance files are buried in drives and spreadsheets, so teams discover notice windows late, cannot see accountable owners, and reconstruct supplier spend by hand.

Who pays

Procurement and operations teams at growing companies managing dozens to hundreds of active supplier agreements without a dedicated contract system.

Business model

Monthly workspace subscription tiered by active supplier contracts and procurement collaborators.

Editorial note

The renewal task is the product's center, not the document folder. Contracts become operational when notice dates, owners, supporting files, and decisions remain connected through the next term.

Avoid premature clause extraction. First prove that procurement staff will maintain a clean register and act from the deadline queue; automation cannot rescue missing ownership or unreliable source dates.

Product goal

Who it serves and what it must change

Target user: Procurement managers, operations owners, and reviewers responsible for supplier renewals.
Problem: Contract terms, deadlines, spend, owners, and compliance files are disconnected, making renewal action late and hard to audit.
Measurable outcome: Every active agreement shows its next notice date, accountable owner, current documents, spend snapshot, and renewal decision before the deadline.

Primary flow

Operator registers agreement and source file
System creates renewal task from notice date
Owner evaluates and advances stages
Reviewers record decision
New term schedules the next cycle

Document: current, expiring, missing, superseded

Core entity outline

Entities and business rules

ContractTerm

Stores one effective agreement period and its commercial dates and value.

Fields: supplier_id, effective_at, ends_at, notice_by, annual_value, currency, status
Relations: Belongs to Supplier, Has many ContractDocuments, Creates RenewalTask

RenewalTask

Tracks owner, stage, deadline, assignments, and final decision for a term.

Fields: contract_term_id, owner_id, stage, due_at, decision, closed_at
Relations: Belongs to ContractTerm, Has many RenewalNotes

ComplianceRequirement

Defines a required supplier document and its current validity.

Fields: supplier_id, document_type, required, valid_until, status
Relations: Belongs to Supplier, May reference ContractDocument

Business rules

Notice date must be on or before term end
Only active terms create reminders
Every stage change records actor and timestamp
A signed new term supersedes but never deletes the prior term
Private documents are inaccessible through permanent public URLs

Architecture and data flow

Components, integrations, and controls

Procurement application

Serve the register, dashboard, renewal board, and supplier details.

Document service

Issue short-lived upload and download URLs and preserve document versions.

Renewal scheduler

Create due states and reminder events from saved notice dates.

Integrations

S3-compatible object storage
Resend transactional email

Data flow

Contract metadata and document upload create a term
Scheduler derives upcoming tasks
Owner actions append renewal history
Closing a renewal creates or ends a term
Reminder events send minimal email content

Failure handling

Quarantine a failed or unscanned upload
Keep reminders retryable without duplicating tasks
Warn when a new term conflicts with an active date range

Security

Organization and role-scoped access
Signed document URLs
Malware scan hook before marking upload available
Audit log for document and term changes

Rate limits

Limit document size and upload count
Batch reminders by owner
Throttle exports and signed URL creation

Deliverables and acceptance

Definition of done for the MVP

Deliverables

Contract register
Renewal dashboard and board
Supplier detail
Private document service
Reminder job
Import template and recovery runbook

Acceptance criteria

A notice deadline appears in the correct urgency bucket
A superseded term remains readable
An unscanned file cannot be downloaded
A failed email does not duplicate the renewal task
Users outside the organization cannot access document URLs

Recommended stack

Enough technology for the first version

Web application

Next.js and TypeScript

Supports dense contract tables, renewal board, and document-aware detail pages.

Data and auth

PostgreSQL with organization roles

Keeps suppliers, terms, tasks, spend snapshots, and access rules relational.

Documents

S3-compatible private storage

Stores signed agreements and compliance files behind short-lived URLs.

Notifications

Resend

Sends owner reminders generated from saved notice dates and task assignments.

Why this is sufficient

The first value comes from trustworthy dates, ownership, and document retrieval. Manual metadata entry is preferable to unsupported AI extraction until teams prove that the renewal pipeline stays current.
