Operating System - Comprehensive Company Digitalization

Industry: Door and frame sales and installation
Size: 45 employees
Location: Katowice, Silesia
Area: Management

The Challenge

Dispersed chaos of processes in Excel and paper

The company operated in complete dispersion - each department maintained its own Excel spreadsheets, processes were not interconnected, and there was no central management system. Leadership had no overview of the company as a whole.

Key challenges:

  • No integrated system - each department worked in isolation (Excel, paper, notes)
  • Chaos in managing sales representatives' meetings - no schedules, duplicate visits, scheduling conflicts
  • Manual settlement of installers - hours of Excel calculations, frequent errors, delayed payments
  • No warehouse control - unknown stock levels, no history, order fulfillment issues
  • Inability to track orders - customers call, nobody knows what stage their order is at
  • Leaflet distribution managed on paper - no control, settlements based on trust
  • No business KPIs - decisions made intuitively without data
  • HR chaos - holidays, absences, payroll settled manually across multiple files
Business impact: The company was operationally inefficient - sales reps lost leads, installers waited for settlements, the warehouse generated errors, and management had no control over profitability. The lack of a system hindered growth and generated losses.

The Solution Process

Building a comprehensive ERP system from scratch

A full digital transformation of the company was carried out - an integrated ERP system was designed and deployed in AppSheet, connecting all departments, processes, and data into a single cohesive management platform with automations, reports, and KPIs.

Actions Taken

Data and process centralization

A unified database was created containing all company information - 30+ interrelated tables: meetings, customers, representatives, orders, line items, purchase orders, warehouse (doors, frames, fittings), installers, leaflet distribution, HR, finance. Every department works within the same system with instant access to up-to-date data.

Tools used:
AppSheetGoogle SheetsRelational Database
Result: Elimination of data duplication, 100% information consistency, instant cross-department data access.

Sales workflow automation

An integrated lead-to-fulfillment process was built - automatic assignment of meetings to representatives by region, meeting schedule with calendar view, quote creation from price list, one-click conversion of quotes to orders, automatic PDF contract generation, SMS deadline reminders.

Tools used:
AppSheet WorkflowsDocument GenerationSMS Automation
Result: Sales cycle shortened by 40%, scheduling conflicts eliminated, quote conversion rate increased by 28%.

Production management system

Comprehensive order management was implemented - automatic breakdown of orders into line items, assignment to installers via scheduling, real-time status tracking, preparation checklists (door issuance, debris removal, painting, dismantling), alerts for approaching deadlines, 'ready for installation' view.

Tools used:
AppSheet Status TrackingConditional FormattingCalendar Views
Result: On-time delivery rate increased from 62% to 89%, installers always know what to do, customers receive up-to-date information.

Automatic installer settlements

An automatic settlement system was created - after completing installation, installers select performed services from a checklist, the system automatically retrieves rates from the price list (individual for each installer), calculates the value of work, and generates a payment summary. Full settlement history, edit capability, export to accounting.

Tools used:
AppSheet AutomationReference TablesPrice Lists
Result: Installer settlement time reduced from 6 hours to 15 minutes, settlement errors reduced from 12% to 0.3%, on-time payments.

Warehouse and stock management

A warehouse system was built - tracking of all products (doors, frames, fittings) with stock levels, defects, customer assignments, automatic issuance for orders, availability control, movement history, defect photo database, automatic stock updates after issues/receipts.

Tools used:
AppSheet InventoryImage GalleryAutomatic Updates
Result: Stock shortages eliminated, product availability at 99%, movement history available for audit.

Leaflet distribution system with settlements

Leaflet distribution management was implemented - distributor database with assigned regions and rates, daily reporting of delivered/distributed leaflets, automatic settlement calculations, leaflet warehouse with deliveries, campaign effectiveness analysis dashboard (costs, coverage, lead-to-meeting conversion).

Tools used:
AppSheet Daily ReportsRegion ManagementCampaign Analytics
Result: Distribution cost control achieved, settlements automated, campaign effectiveness increased by 34%.

Business KPI dashboard

A central management dashboard was created - sales KPIs (value, volume, conversion), production KPIs (on-time rate, installer efficiency), warehouse KPIs (stock levels, turnover), finance KPIs (revenue, costs, margins), HR KPIs (absences, personnel costs). Time filters, comparisons, trends, exports.

Tools used:
AppSheet DashboardsCharts & AnalyticsKPI Tracking
Result: Management has a real-time view of the company, data-driven decisions, issue identification within 24 hours.

Business benefits

  • Full centralization - one platform instead of dozens of Excel spreadsheets
  • Automated installer settlements - saving 6 hours per month, errors eliminated
  • On-time delivery control - increase from 62% to 89% through alerts and scheduling
  • Warehouse management - 99% product availability, audit-ready movement history
  • Leaflet distribution system - full control over costs and campaign effectiveness
  • Management view - real-time business KPI dashboard
  • Better customer experience - customers always know what stage their order is at
  • Elimination of duplication - data entered once, accessible everywhere
  • Mobility - sales reps and installers work from their phones in the field
  • Scalability - the system grows with the company, new features easy to add
This was a game-changer for our company. Before, every department lived its own life - sales reps in one Excel, installers in another, warehouse in a third. Now everything is in one place. I can see in real time how many orders we have, what the warehouse stock looks like, whether installers have been settled. The system paid for itself within 3 months just from the time saved on settlements.
