ERP Development in Zurich, Switzerland

Manufacturing / Precision Instruments

A Zurich precision manufacturing company (CHF 85 million annual revenue, 320 employees, manufacturing precision measurement instruments sold to pharmaceutical, semiconductor, and aerospace industries globally) was running an outdated Abacus installation (version 2016) supplemented by: 14 Excel spreadsheets for production planning and scheduling, a standalone quality management system (Lotus Notes-based — end of vendor support), a separate CRM (Act! — no integration with Abacus), and manual customs processing (paper-based declarations prepared by a logistics coordinator using the Swiss customs online portal directly). The fragmented system created: production visibility gaps (no real-time view of work-in-progress, machine utilisation, or delivery timelines — the production manager relied on daily walk-throughs and Excel updates), quality management risk (the quality system was isolated — non-conformance reports, customer complaints, and corrective actions were tracked in Lotus Notes with no connection to production records, making root cause analysis difficult and ISO 13485 audit preparation time-consuming), financial reporting delays (monthly close took 12 business days — the finance team spent days reconciling data between Abacus, the production spreadsheets, and the quality system before producing management accounts), and customer frustration (customers asking for delivery dates received estimates based on the production manager's memory rather than system data — leading to missed commitments and eroded trust). The CEO set objectives: real-time production visibility, integrated quality management meeting ISO 13485 requirements, monthly close within 5 business days, and accurate delivery date commitments.

We modernised the ERP over 18 weeks, building on the existing Abacus foundation and adding custom modules for manufacturing-specific requirements. Abacus upgrade and configuration (weeks 1-4): upgraded Abacus to the current version with: updated Swiss VAT configuration (current rates and reporting format), Swiss payroll update (current AHV/IV/EO rates, BVG coordination amounts), financial reporting aligned with Swiss OR requirements, and multi-currency handling (the company invoiced in CHF, EUR, USD, and JPY — each currency requiring correct treatment for VAT, financial reporting, and currency gain/loss). Production management module (weeks 3-10): we built a custom production management module (Next.js frontend, PostgreSQL backend) integrated with Abacus: work order management (creation, scheduling, tracking, and completion of production work orders — linked to Abacus sales orders for complete order-to-cash traceability), production scheduling (visual scheduling board showing machine allocation, work order status, and resource availability — replacing the 14 Excel spreadsheets with a real-time, drag-and-drop scheduling interface), shop floor data collection (tablet-based terminals on each production work centre — operators logged: work order start/stop times, quantity produced, quantity rejected, machine status, and any issues or deviations — providing real-time production data rather than end-of-day Excel updates), and delivery date calculation (the system calculated delivery dates based on: current production schedule, available capacity, material availability, and standard production lead times — enabling accurate, system-generated delivery commitments for customer orders). Quality management integration (weeks 5-12): the quality management system was rebuilt as an integrated module: non-conformance management (NCRs created from shop floor data collection, incoming inspection, or customer complaints — linked to the specific work order, batch, and customer order for traceability), CAPA management (corrective and preventive actions workflow — investigation, root cause analysis, action plan, implementation, effectiveness verification — with timeline tracking and escalation for overdue actions), customer complaint management (complaint receipt, investigation, response, and closure — linked to the original order, production batch, and any related NCRs — providing complete complaint-to-root-cause traceability), inspection planning (inspection plans linked to product specifications — defining inspection points, characteristics, tolerances, and sampling plans for each product type), and document control (controlled documents — work instructions, specifications, procedures — with version management, approval workflows, and distribution tracking meeting ISO 13485 requirements). The quality module connected directly to production and Abacus — a non-conformance in incoming inspection automatically blocked the affected material in inventory, a customer complaint automatically linked to the production batch and triggered an investigation workflow. Swiss customs integration (weeks 8-14): automated customs processing: export declaration generation (based on the Abacus sales order — product classification (HS code), country of destination, value, weight, and origin — formatted for the Swiss customs e-dec system), preferential origin management (tracking the Swiss/EU origin of components to determine whether finished products qualified for preferential duty treatment under the EU-Switzerland bilateral agreements — issuing EUR.1 movement certificates for qualifying shipments), and import declaration preparation (for purchased components — classifying incoming goods, calculating customs duty, and preparing import declarations). Financial reporting integration (weeks 10-16): Abacus financial reporting was enhanced with: automated production costing (actual production costs — materials, labour (from shop floor time recording), machine costs, overheads — posted to Abacus automatically from the production module), work-in-progress calculation (real-time WIP valuation based on completion status of open work orders — eliminating the manual WIP spreadsheet that had been a persistent source of monthly close delays), and management dashboard (real-time KPIs — revenue, order intake, backlog, production output, quality metrics, delivery performance — displayed on a web dashboard accessible to management without waiting for the monthly close).

The modernised ERP deployed in phases over 6 weeks following development completion. Production visibility: real-time production status replaced the Excel-based system. The production manager could see: every work order's status (not started, in progress, complete, on hold), machine utilisation by work centre (identifying bottlenecks and idle capacity), work-in-progress across the factory floor, and projected delivery dates for every customer order. Production scheduling accuracy improved from approximately 65% on-time delivery (based on Excel estimates) to 91% (based on system-calculated dates with real-time capacity data). Quality management: ISO 13485 surveillance audit (conducted 4 months after deployment) resulted in zero non-conformities related to the quality system — the auditor specifically noted the traceability from customer complaint through investigation to root cause and corrective action as a strength. NCR processing time: reduced from an average of 8 days (manual Lotus Notes workflow) to 3 days (integrated workflow with automatic notifications and escalation). CAPA closure rate: 94% within defined timelines (from 71% — the automated escalation prevented CAPAs from lingering unresolved). Financial reporting: monthly close reduced from 12 business days to 4.5 business days. The primary improvement drivers: automated production costing (eliminating 3 days of manual cost allocation), automated WIP calculation (eliminating 2 days of manual WIP spreadsheet work), and integrated data (eliminating 2 days of cross-system reconciliation). Management now received preliminary financial results by the 5th business day of each month — compared to the 15th previously. Customs processing: export declaration preparation time reduced from 45 minutes per shipment (manual data entry into customs portal) to 5 minutes (automated generation from sales order data with human review). The company processed approximately 1,200 export shipments annually — saving approximately 800 hours of logistics coordinator time. Preferential origin tracking enabled the company to correctly claim duty preferences on 85% of EU-bound shipments — previously, the company had not systematically tracked origin and was not claiming preferences, resulting in customers paying unnecessary customs duty (estimated at EUR 180,000 annually — which the company's competitors who did claim preferences did not impose). Customer satisfaction: delivery date accuracy improvement (65% to 91% on-time) significantly reduced customer complaints about late delivery. Customer complaints decreased 38% overall. The ability to provide accurate, real-time delivery information (rather than estimates) improved customer trust and sales team credibility. Financial impact: production efficiency improvement: CHF 1.2 million annually (better scheduling, reduced idle time, faster changeovers informed by data). Quality cost reduction: CHF 340,000 annually (faster NCR resolution, reduced scrap, fewer customer returns). Financial reporting efficiency: CHF 180,000 annually (reduced close time, eliminated manual reconciliation). Customs optimisation: CHF 260,000 annually (duty preference claims, reduced processing time). Customer retention: estimated CHF 800,000 annually (reduced complaints, improved delivery reliability). Total annual benefit: CHF 2.78 million. Implementation cost: CHF 420,000. First-year ROI: 5.6x. Ongoing cost: CHF 6,000/month (hosting, maintenance, Abacus licensing).
