Supplier Management Dashboard
Build a supplier management system with vendor database, performance tracking, contract alerts, and procurement analytics.
Supplier management for growing businesses
As a business grows, the number of suppliers multiplies — software subscriptions, office supplies, contractors, raw materials, shipping services, and professional services. Without a system, supplier information is scattered across email inboxes, shared drives, and individual spreadsheets. Contract renewal dates are missed, spending creeps up unnoticed, and no one knows if a supplier is actually delivering good value. A supplier management dashboard centralises this information and provides visibility into vendor relationships, spending patterns, and performance. Ask Claude Code: Create a Next.js project with TypeScript, Tailwind, and Prisma for a supplier management dashboard. Define the database schema. Supplier (id, name, category as software or services or supplies or contractors or logistics or professional, contactName, contactEmail, contactPhone, website, address, status as active or inactive or on_hold, riskLevel as low or medium or high, createdAt, notes). Contract (id, supplierId, title, startDate, endDate, autoRenew boolean, renewalNoticeDays as the number of days before end date you must give notice to cancel, value as total contract value in pence, billingFrequency as monthly or quarterly or annually or one_time, paymentTerms as string like Net 30, documentUrl optional for the contract PDF). Invoice (id, supplierId, contractId optional, invoiceNumber, issueDate, dueDate, amount, status as pending or paid or overdue or disputed, paidDate optional). PerformanceReview (id, supplierId, reviewDate, qualityScore as 1 to 5, deliveryScore as 1 to 5, communicationScore as 1 to 5, valueScore as 1 to 5, overallScore computed average, reviewerName, comments). Seed with 15 suppliers, 20 contracts, 100 invoices over the last 12 months, and 30 performance reviews.
Supplier directory and profiles
The supplier directory is the single source of truth for all vendor information. Ask Claude Code: Create a supplier directory page at src/app/suppliers/page.tsx. Show a searchable, filterable table of all suppliers with: name, category (with coloured badge), status, number of active contracts, total spend in the last 12 months, average performance score (as stars), and risk level. Filter by category, status, and risk level. Sort by any column. Search by name or contact information. Build detailed supplier profiles. Ask Claude Code: Create a supplier detail page at src/app/suppliers/[id]/page.tsx. The profile shows: company information (name, category, contact details, website, address, notes), contract summary (active contracts with their values and end dates, expired contracts), financial summary (total spend this year, total spend all time, average monthly spend, payment history with on-time percentage), performance history (all reviews as a timeline, average scores by dimension, trend chart showing performance over time), and associated documents (contracts, invoices, correspondence). Add a supplier onboarding checklist. Ask Claude Code: When adding a new supplier, show a checklist of required information and actions: basic company details (required), contract uploaded (required), bank details for payment (required), insurance certificate verified (for service suppliers), NDA signed (for suppliers with data access), compliance certifications (ISO, SOC2, etc. — for relevant categories), and first performance review date set. Track completion percentage and flag incomplete supplier profiles. Add a supplier comparison view. Ask Claude Code: Let users select 2 to 4 suppliers in the same category and compare them side by side: contract values, performance scores, spend trends, and payment terms. Highlight the best value: the supplier with the highest performance-to-cost ratio. This is useful when evaluating whether to switch suppliers or negotiate better terms. Common error: supplier data goes stale quickly. Contacts leave, addresses change, and companies are acquired. Add a data freshness indicator showing when each supplier's information was last verified. Prompt for re-verification every 6 months.
Contract management and renewal alerts
Contract management prevents two expensive mistakes: paying for services you no longer need (because the auto-renewal was not cancelled) and losing services you do need (because the renewal was forgotten). Ask Claude Code: Create a contract management page at src/app/contracts/page.tsx. Show all contracts in a table with: supplier name, contract title, start and end dates, value, billing frequency, auto-renewal status, days until expiry, and status (active in green, expiring soon in yellow, expired in red). Add a timeline view showing all contracts on a horizontal timeline so you can see the portfolio of commitments over the next 12 months. Build the renewal alert system. Ask Claude Code: Create a contract alert engine at src/lib/contract-alerts.ts. For each active contract, calculate alert dates based on the renewal notice period. If a contract auto-renews and requires 30 days notice to cancel, set an alert for 45 days before the end date (extra buffer) and another at 35 days (approaching notice deadline). Send email alerts at these dates with: the contract details, the renewal terms, the action required (review and decide whether to renew, renegotiate, or cancel), and a direct link to the contract details page. Add a contract renewal workflow. Ask Claude Code: When a contract approaches renewal, create a renewal review task. The reviewer evaluates: the supplier's performance scores (is the supplier delivering value?), the contract's cost versus market rates (are we overpaying?), the usage level (are we actually using what we are paying for?), and alternative suppliers (are there better options?). The review results in a decision: renew as-is, renegotiate terms, switch supplier, or cancel. Log the decision and its rationale in the contract record. Build a contract document repository. Ask Claude Code: Each contract has associated documents — the signed agreement, amendments, addenda, and correspondence. Store document references in the database with the contract ID. Show all documents on the contract detail page with upload dates and a download button. Add version tracking: when a contract is amended, upload the new version and link it to the original. Common error: auto-renewal dates are easy to miss. Create a monthly contract review digest sent to the finance team: contracts renewing in the next 90 days, contracts renewed automatically in the last 30 days (in case any should have been cancelled), and total committed spend for the upcoming quarter.
Spend analysis and budget tracking
Spend analysis reveals where your money goes and whether you are getting value. Without it, costs creep up invisibly — a subscription here, a rate increase there. Ask Claude Code: Create a spend analysis dashboard at src/app/spend/page.tsx. Show total spend by time period as a bar chart (monthly spend for the last 12 months). Break down spend by category as a pie chart: what percentage goes to software, services, supplies, contractors, and logistics. Show spend by supplier as a ranked list: the top 10 suppliers by total spend with their percentage of total spend. The top 3 suppliers often account for 50 percent or more of total spending — these are your most important vendor relationships. Build trend analysis. Ask Claude Code: Create spend trend charts for each category. Show month-over-month changes with annotations for significant events (new contract started, price increase, added new supplier). Calculate the year-over-year change for each category. Flag categories where spending increased more than 15 percent year-over-year — these need review to determine if the increase was planned and justified. Add budget tracking. Ask Claude Code: Let users set annual budgets by category. Show a budget versus actual chart for each category: the budgeted amount as a horizontal line, the actual cumulative spend as an area chart, and a projection line extending the current spending rate to the year end. If the projection exceeds the budget, show a warning: Software spending is projected to exceed the annual budget by 12 percent. Review subscriptions for consolidation opportunities. Build a subscription tracker. Ask Claude Code: Many modern suppliers are software subscriptions billed monthly or annually. Create a dedicated subscription view showing: all active subscriptions, their monthly cost, the annual cost, the last used date (for software subscriptions — when was the tool last accessed?), and the number of seats or licenses versus the number of active users. Flag underutilised subscriptions: if you pay for 20 seats but only 8 are active, you are wasting 60 percent of the cost. Generate a savings opportunity list showing subscriptions that could be downgraded or cancelled. Common error: spend analysis requires consistent data. If invoices are categorised inconsistently (one person categorises a web hosting bill as Software, another as Infrastructure), the analysis is misleading. Create clear category definitions and train the team on consistent categorisation.
Performance scorecards and risk management
Not all suppliers are equal. Performance scorecards quantify supplier quality so you can reward good suppliers, improve mediocre ones, and replace poor ones. Ask Claude Code: Create a supplier scorecard system at src/lib/scorecards.ts. Each scorecard evaluates a supplier across four dimensions. Quality (weight 30 percent): are the deliverables meeting specifications? For product suppliers: defect rate, return rate. For service suppliers: error rate, rework frequency. Delivery (weight 25 percent): are deliveries on time? Calculate the on-time delivery percentage from invoices and order records. Communication (weight 20 percent): is the supplier responsive and proactive? Response time to enquiries, proactive issue notification, regular status updates. Value (weight 25 percent): is the price competitive for the quality delivered? Compare to market rates and alternative suppliers. Build the scorecard UI. Ask Claude Code: Create a scorecard page for each supplier showing: the overall weighted score as a large number (out of 5) with a colour indicator, individual dimension scores as a radar chart, the score trend over the last 6 reviews, comparison to the category average (is this supplier above or below average for their category?), and specific comments from each review. Build a risk assessment system. Ask Claude Code: Create a risk evaluator at src/lib/risk.ts. Calculate supplier risk based on: financial dependency (if this supplier provides more than 20 percent of your spend in their category, you are highly dependent — risk increases), performance trend (declining performance scores indicate increasing risk), contract status (month-to-month or expiring contracts are higher risk than long-term agreements), single source risk (if this supplier is the only one in their category, losing them has no alternative — high risk), and payment disputes (suppliers with disputed invoices have relationship friction). Assign an overall risk level: low, medium, or high. Generate a risk heatmap. Ask Claude Code: Create a visualisation with suppliers on one axis and risk factors on the other. Each cell is coloured by risk level. This immediately shows which suppliers pose the greatest risk and which risk factors are most prevalent across your supplier base. Common error: performance reviews are only useful if they are conducted regularly. Set up automated reminders: every supplier should be reviewed at least quarterly. If a review is overdue, show a prominent alert on the supplier profile and the main dashboard.
Procurement workflow and deployment
When you need a new supplier or need to purchase from an existing one, a procurement workflow ensures consistency and approval. Ask Claude Code: Build a purchase request system at src/app/procurement/page.tsx. A purchase request includes: the supplier (select from existing or request a new supplier), the description of what is being purchased, the estimated cost, the business justification, the budget category, and the urgency level. Create an approval workflow. Ask Claude Code: Define approval rules based on the request value. Under 500 pounds: auto-approved with notification to the finance team. 500 to 5000 pounds: requires manager approval. Over 5000 pounds: requires director approval. Over 25,000 pounds: requires board approval. Show the approval chain on each request. Approvers receive an email notification with the request details and Approve and Reject buttons (which link to the approval page). Track the approval time — if approval takes more than 3 business days, escalate to the next level. Add a supplier evaluation workflow for new suppliers. Ask Claude Code: When a new supplier is proposed, trigger an evaluation checklist. Financial check (is the company financially stable? Check Companies House data for UK suppliers), reference check (request and review references from other customers), compliance check (verify required certifications and insurance), competitive comparison (compare the proposed supplier's terms to 2 alternatives), and trial period (if applicable, set up a 30-day trial before committing to a long-term contract). Log the evaluation results and the decision. Deploy the supplier management dashboard. Ask Claude Code: Configure production deployment on Vercel with a PostgreSQL database. Set up cron jobs for: daily contract renewal alerts (check for contracts within their alert window), weekly spend summary emails (total spend this week by category), monthly performance review reminders (prompt for reviews due this month), and quarterly supplier risk reassessment (recalculate risk levels based on latest data). Test with real supplier data: add your actual suppliers, contracts, and recent invoices. Run the spend analysis and verify the numbers match your expectations. Set up the first round of performance reviews. The system is complete — a professional supplier management platform that replaces spreadsheet chaos with structured, automated vendor oversight.
