The Problem with Off-the-Shelf ERP
Manufacturing and wholesale businesses have some of the most complex operational requirements of any sector. Stock moves through multiple stages — raw materials arrive, components are assembled, finished goods are packed, orders are picked and despatched. At every stage, you need to know exactly what you have, where it is, and what is committed to existing orders. Most off-the-shelf ERP systems promise to handle all of this, but the reality is often different. You end up paying for modules you do not need, fighting the software to match your actual workflows, and building workarounds in spreadsheets because the system cannot accommodate how your business actually operates.
We take a different approach. Rather than forcing your processes into someone else's software, we build bespoke systems that reflect how your warehouse, production floor, and sales team actually work. The result is software that your staff find intuitive, that produces the reports your management team needs, and that scales as your business grows — without the licensing costs and inflexibility of enterprise ERP platforms.
What We Build for Manufacturers and Wholesalers
Inventory Management
Accurate stock control is the foundation of any manufacturing or wholesale operation. We build inventory management systems that track stock levels in real time across multiple warehouses, bin locations, and storage zones. Every goods receipt, stock movement, adjustment, and despatch is recorded and reflected immediately in available stock figures. Reorder points trigger automated alerts. Stock valuations are calculated using the costing method that suits your business — whether that is weighted average, FIFO, or standard costing.
For businesses managing thousands of SKUs, we build advanced search and filtering interfaces that let warehouse staff find products instantly by code, description, barcode, or supplier reference. Barcode scanning integration — via handheld scanners or iPads running FileMaker Go — eliminates manual data entry errors at goods-in, during stock counts, and at the picking stage. The system maintains a complete movement history for every item, giving you full traceability from supplier delivery through to customer despatch.
Bill of Materials and Production
For manufacturers, the Bill of Materials is at the heart of production planning. We build multi-level BOM structures that define exactly which components and sub-assemblies go into each finished product, with quantities, unit costs, and supplier details at every level. When a production order is raised, the system checks component availability against current stock, identifies shortages, and calculates what needs to be procured before production can begin.
Production scheduling modules allow you to plan manufacturing runs, allocate resources, and track work-in-progress. As components are consumed and finished goods are produced, stock levels update automatically. Wastage and scrap are recorded against each production run, giving you accurate costing data and visibility into production efficiency over time. For businesses running continuous or batch production processes, we build scheduling tools that optimise throughput while maintaining quality tracking at every stage.
Order Processing and Invoicing
From initial quotation through to final invoice, we build end-to-end order management workflows. Sales orders are entered once and flow through the system — checking stock availability, generating pick lists, producing packing notes, and creating invoices without re-keying data at any stage. Credit control modules track payment terms, flag overdue accounts, and produce aged debtor reports. For businesses that handle returns, we build credit note and returns processing workflows that update stock and financial records simultaneously.
Purchase order management works the same way on the procurement side. Reorder suggestions are generated from stock levels and demand forecasts. Purchase orders are raised, sent to suppliers, and matched against goods receipts when deliveries arrive. Any discrepancies between what was ordered and what was received are flagged immediately for resolution. The system maintains full purchase history per supplier, making it straightforward to evaluate supplier performance on price, lead time, and delivery accuracy.
Warehouse Modules
Warehouse management goes beyond knowing what stock you have. It involves optimising how goods move through your facility. We build warehouse modules that handle goods-in processing, putaway logic, pick-path optimisation, and despatch workflows. For businesses with multiple despatch methods — courier, pallet network, own vehicles — the system can integrate with carrier APIs to generate shipping labels and tracking numbers directly from the despatch screen.
Stock counting modules support both full stock takes and rolling cycle counts, with variance reporting that highlights discrepancies for investigation. For businesses operating from multiple warehouses or using third-party logistics providers, we build inter-warehouse transfer workflows and stock visibility dashboards that show consolidated stock across all locations.
Serial and Batch Tracking
For businesses that need full traceability — whether for regulatory compliance, warranty management, or quality assurance — we build serial number and batch tracking into every relevant transaction. Each serialised item is tracked from goods receipt through to customer despatch, with a complete audit trail showing every location, movement, and handling event. Batch-tracked products are managed with expiry date monitoring, FIFO picking enforcement, and the ability to trace a batch number back to its supplier lot and forward to every customer who received it.
This level of traceability is essential for product recalls, warranty claims, and regulatory audits. Rather than spending days manually piecing together paper records, your team can pull a complete product history in seconds.
BusinessMan ERP — A Real Example
Our work on BusinessMan ERP is a comprehensive example of what we deliver for the manufacturing and wholesale sector. BusinessMan is a full-featured ERP system built on FileMaker, covering CRM, inventory management, purchasing, sales order processing, invoicing, and warehouse operations. It was developed for Computech, a business that needed an integrated system to replace disconnected tools and manual processes.
The system handles multi-warehouse stock control, Bill of Materials, serial number tracking, and automated purchasing workflows. It is the kind of software that enterprise vendors charge six-figure licence fees for — but built bespoke to match the client's exact requirements, without the bloat, without the per-seat licensing, and without the two-year implementation timeline.
Why FileMaker for Manufacturing
FileMaker is a rapid application development platform, which means we can deliver a working system faster and at lower cost than traditional ERP development. But speed does not mean compromise. FileMaker handles complex relational data models, integrates with barcode scanners and external APIs, supports multi-user concurrent access, and runs on Mac, Windows, iPad, and through web browsers via WebDirect. For manufacturing businesses that need warehouse floor staff using iPads alongside office staff on desktops, FileMaker provides a single platform that covers both use cases natively.
We also build integrations with accounting software like Xero and Sage, shipping APIs, and e-commerce platforms — connecting your ERP with the tools your business already relies on.
If your manufacturing or wholesale business is running on spreadsheets, disconnected systems, or an off-the-shelf ERP that does not fit, we would welcome the chance to discuss what a bespoke solution could look like. No obligation, no pressure — just a practical conversation about your operations and how software can support them.
