StokKantor

Track office stock before it runs out.

StokKantor is an inventory management application for office supplies and shared assets, built for teams that need clear visibility into what they have, what is running low, and what has been issued. It helps office managers, admins, and finance teams reduce stockouts, prevent overbuying, and keep simple but accurate records without relying on spreadsheets.

Business Goals

  • Reduce office supply stockouts by 60% within 3 months of launch.
  • Cut manual inventory reconciliation time by 70% within 8 weeks.
  • Increase monthly active usage by office admins to 80% of registered users within 90 days.
  • Reduce unnecessary duplicate purchasing by 25% within 6 months.
  • Achieve at least 90% inventory record accuracy on counted items within the first quarter.

User Goals

  • See current stock levels and low-stock alerts in one place.
  • Record stock in, stock out, and adjustments in under 30 seconds per transaction.
  • Find item locations and responsible departments quickly.
  • Generate simple purchase and usage reports for management.
  • Audit who changed stock and when without using spreadsheets.

Non-Goals

  • Not a full ERP or accounting system.
  • Not a warehouse management system for large multi-site logistics.
  • Not handling vendor procurement approvals beyond basic reorder suggestions.
  • Not optimizing complex serial-number or lot-tracking workflows for manufacturing.

Dina used to manage office supplies in a spreadsheet and a notebook, which meant she only noticed shortages when employees complained. Every month she spent hours reconciling counts, guessing what had been used, and chasing down missing items across departments.

With StokKantor, Dina logs stock movements as they happen, sees low-stock alerts before items run out, and exports clean reports for finance in a few clicks. The office stops overbuying, employees get the supplies they need on time, and management finally has a reliable picture of inventory and spend.

Potential Challenges

  • Risk: inaccurate inventory due to inconsistent manual entry. Mitigation: use validation, templates, import checks, and mandatory reason codes for adjustments.
  • Risk: slow reports as data grows. Mitigation: precompute aggregates, add indexes, and paginate all large views.
  • Risk: duplicate item records from multiple users. Mitigation: duplicate detection, SKU rules, and merge workflows.
  • Risk: adoption friction for non-technical office staff. Mitigation: mobile-friendly UI, simple defaults, and guided onboarding.
  • Risk: permission errors or accidental edits across departments. Mitigation: role-based access control, audit logs, and confirmation dialogs for destructive actions.

Core features:
1. Authentication, tenant/company setup, and role-based access control for admin, viewer, approver, and finance roles.
2. Inventory item management with fields: name, SKU/internal code, category, unit, location, minimum stock, reorder quantity, cost, photo, notes, archived flag.
3. Stock movements: stock in, stock out, transfer, adjustment. Every movement must write an immutable audit record with timestamp, user, department, quantity, reason, and optional reference number.
4. Dashboard with low-stock, out-of-stock, recent movements, and top consumed items.
5. CSV import for items with row-level validation and duplicate detection.
6. Reports page with date filters, category/location filters, export to CSV and Excel.
7. Alerts page for low-stock items and reorder status.
8. Cycle count mode for physical counts and variance tracking.

Primary screens:
Dashboard, Items list, Item detail, New/Edit item form, Create movement form, Alerts/Reorder screen, Reports screen, Audit log screen, Settings screen for company, roles, locations, and thresholds.

Data model:
Company, User, Role, Department, Location, Category, Item, InventoryBalance, StockMovement, AuditLog, AlertRule, CycleCount, CycleCountLine, ImportJob.

Important UX rules:
Fast table-based admin UI, sticky filters, searchable selects, optimistic updates where safe, strong form validation, negative stock prevention by default, clear empty states, and accessible color contrast.

Implementation details:
Use PostgreSQL with indexed tenant-scoped tables, Prisma migrations, server actions or API routes for CRUD, Zod validation, background jobs for email alerts and CSV import processing, and chart components for dashboard metrics. Seed demo data for one office with stationery, pantry, and IT items. Make the app production-ready with responsive layout, error handling, loading states, and audit-safe mutation flows.
