Most UK businesses do not need supply chain management software because their supply chain is simple. They need it because their supply chain is specific, and the off-the-shelf tools they have tried cannot handle that specificity. You end up with a warehouse team on one system, procurement on another, accounting on a third, and a spreadsheet holding it all together.
We build custom supply chain management software that fits the way your business actually works. ByteGears is a London consultancy that builds software exclusively for UK businesses. You pay once, you own the code, and it connects your procurement, inventory, warehousing, and fulfilment into a single system designed around your workflows, not around a vendor’s module structure.
Why off-the-shelf supply chain software falls short
Packaged SCM platforms from the likes of SAP, Oracle, Microsoft Dynamics 365, and Kinaxis are built for the broadest possible market. They demo well. Then reality sets in:
- Rigid approval workflows. Most businesses have non-standard purchase approval rules. Orders under £1,000 from approved suppliers might be auto-approved; orders over £5,000 need director sign-off; emergency orders bypass normal flow. Off-the-shelf systems force you into their approval logic, and customising it is expensive.
- Per-user pricing that scales against you. Dynamics 365 SCM starts at roughly £290 per user per month. At 50 users, that is over £170,000 a year in licence fees alone. Oracle and SAP are comparable or worse. You never own the software, and the bill keeps growing.
- Implementation timescales measured in quarters, not weeks. Enterprise SCM implementations routinely take 6 to 12 months. Blue Yonder deployments typically run 12 to 24 months with professional services costs matching or exceeding the licence fee. Mid-market platforms like Kinaxis or Infor still take 3 to 6 months.
- Integration that does not actually work in real time. Your ERP, warehouse system, e-commerce platform, and logistics partners each hold data the others cannot see. Many SaaS integrations sync in batches (daily or weekly), not in real time, which means you are making decisions on stale data. Inventory visibility lag leads to double-selling and overselling.
- Poor mobile experience. Warehouse and delivery staff are given desktop software squeezed onto a phone screen. Usability is poor, adoption is low, and people go back to clipboards.
- Forecasting that does not learn your patterns. Out-of-the-box forecasting algorithms are generic. They fit all businesses and optimise none. If your demand is shaped by promotions, weather, seasonal cycles, or supplier lead times, you need models trained on your data, not on averages.
- UK compliance as an afterthought. International platforms are slow to support GDPR specifics, HACCP, GMP, COSHH, or Making Tax Digital integration. You end up managing compliance outside the system.
The knock-on costs are worse than the licence fee. Staff waste hours reconciling data by hand. Every forced workflow change means retraining. Decisions stall because the information is locked inside a system that was not designed for your process.
How ByteGears builds supply chain software differently
We start from your operation, not from a template.
We map your workflows first
Before writing code, we sit with your team and document how products, orders, and information actually move through your business. We map your procurement rules, approval thresholds, warehouse processes, and fulfilment logic. The software follows that map rather than imposing a new one.
You pay once and own the result
No subscriptions, no per-seat licensing. One fixed investment. While enterprise SaaS can cost £36,000 to £120,000 a year in user licences alone for a team of 100, a custom build has fixed annual maintenance of £5,000 to £15,000. Most clients break even within 18 to 24 months.
We connect what you already use
Your ERP, accounting package (Xero, Sage, QuickBooks), e-commerce platform (Shopify, WooCommerce, Magento), and logistics partners (DHL, Parcelforce, 3PL providers) talk to each other through secure REST APIs and webhooks. Real-time sync, not daily batch imports. Each integration typically takes two to four weeks to build and test.
UK compliance is built into the architecture
GDPR with full audit trails and data residency on UK servers. Batch traceability for pharma (GMP, MHRA). Expiration tracking and HACCP support for food. COSHH logging for chemicals. MTD-compatible accounting integration. Our London team tracks regulatory changes so your system stays current.
The system grows with you
We build modular. When you add a warehouse, a new supplier, or another sales channel, the software accommodates it without a rebuild. Multi-site inventory visibility, multi-currency support, and new integrations can be added in phases.
Support is local and fast
Same-day responses for critical issues. Training at your premises if you need it. We are in London, so you are never waiting on a different timezone.
What we build into every supply chain system
Each project is different, but these modules come up in nearly every engagement:
Inventory and warehouse management
- Real-time stock levels across multiple warehouses, stores, and 3PL locations
- Barcode and RFID scanning for receiving, picking, packing, and shipping
- Batch and serial number tracking with lot traceability for recalls
- Automated stock allocation rules (FIFO, LIFO, by expiration date)
- Low-stock alerts, reorder point triggers, and safety stock calculations
Procurement and supplier management
- Purchase order creation with configurable approval workflows (amount thresholds, supplier tiers, emergency bypass)
- Supplier scorecards covering on-time delivery, quality, pricing, and contract terms
- Supplier vetting and qualification records (critical for GMP, FSMA, REACH compliance)
- Automated purchase order generation when stock hits reorder points
Order fulfilment and logistics
- Order tracking from supplier PO through to customer delivery
- Automated exception alerts (late shipments, short deliveries, quality holds)
- Multi-channel order routing for retailers selling online, in-store, and through marketplaces
- Integration with carriers and 3PL partners for real-time shipment tracking
Demand planning and forecasting
- Statistical forecasting using your historical sales data
- Machine learning models trained on your patterns, adjusted for promotions, seasonality, and external signals
- Manual override capability so your planners can apply domain knowledge
- Predictive replenishment that accounts for supplier lead times and minimum order quantities
Dashboards and reporting
- Live dashboards showing inventory levels, shipment status, supplier performance, and demand trends
- KPI tracking aligned to your business metrics (inventory turns, fill rate, on-time delivery by region, gross margin by supplier)
- Drag-and-drop report builder for ad-hoc analysis
- Data export in CSV, Excel, and PDF
Security and access control
- Role-based permissions so warehouse staff, procurement, planning, and finance each see only what they need
- Field-level security for sensitive data (pricing, supplier terms, cost data)
- Full audit trail with user attribution and timestamps
- Encryption at rest and in transit, automated backups, UK data residency
Mobile access
- Purpose-built mobile interface for warehouse staff, not a squeezed desktop view
- Barcode scanning, goods receiving, stock counts, and pick-pack-ship workflows
- Offline mode for sites with poor connectivity
How delivery works
Four phases, typically three to five months total. We can deliver an MVP in as little as eight weeks if you need something working fast.
Phase 1: Discovery and planning (2-4 weeks)
Onsite workshops where we document your current processes, pain points, integration requirements, and compliance needs. We map your data: products, suppliers, warehouses, customers, orders, and movements. You get a detailed blueprint and fixed-price quote before development starts.
Phase 2: Development (8-16 weeks)
Our UK engineers build the system with weekly progress reviews. We ship core functionality first (inventory, purchase orders, basic reporting) so you can start using it while we build the rest. Each integration (accounting, e-commerce, logistics) is built and tested independently.
Phase 3: Testing and deployment (2-4 weeks)
User acceptance testing with your team across every role. Data migration from your existing systems, validated and reconciled. Full cutover during a quiet period, with parallel running if needed.
Phase 4: Training and support (ongoing)
Role-specific training for warehouse staff (1-2 days), procurement (1-2 days), planning and inventory (2-3 days), and finance (1-2 days). 24 months of included support from our UK team. Ongoing ad-hoc support for 4 to 8 weeks post-launch while the team settles in.
What it costs
Custom development means upfront investment, but the long-term numbers usually beat SaaS convincingly:
- No recurring licence fees. Enterprise SaaS SCM can cost £36,000 to £120,000 a year in per-user fees for a team of 100. Custom software has fixed annual maintenance of £5,000 to £15,000.
- You own the asset outright. No vendor lock-in, no API restrictions, no forced upgrades. The code is yours.
- Fixed-price contracts. No scope creep surprises. Phased delivery is an option if budget is tight.
- Savings start immediately. We automate your most time-consuming processes first. Automated purchase orders, real-time stock visibility, and exception alerts typically pay for themselves within months.
Projects typically range from £25,000 to £75,000 depending on complexity. A single-site MVP with inventory management, purchase orders, and basic reporting sits at the lower end. Multi-site systems with demand forecasting, multiple integrations, and industry-specific compliance modules sit higher. We will give you a transparent quote during a free consultation based on your actual requirements.
For context, a mid-market SaaS deployment (Dynamics 365, Infor) typically costs £160,000 to £650,000 over three years in licence, implementation, and support costs. Enterprise platforms (SAP, Oracle, Blue Yonder) run well into seven figures.

Common Questions About Custom Supply Chain Management Software
How does custom development cost compare to SaaS supply chain software?
Enterprise SaaS platforms like Dynamics 365 charge from £290 per user per month. At 50 users that is over £170,000 a year in licence fees alone, before implementation, customisation, or integration costs. A custom build from ByteGears typically costs £25,000 to £75,000 as a one-off investment with ongoing maintenance of £5,000 to £15,000 per year. Most clients break even within 18 to 24 months.
What's the typical development timeline?
An MVP covering a single site with inventory management, purchase orders, and basic reporting takes 8 to 12 weeks. A more complete system with multi-site inventory, demand forecasting, supplier tracking, and accounting integration typically takes 16 to 20 weeks. We ship working software early and iterate from there.
Can you integrate with our existing systems?
Yes. We regularly connect with UK accounting packages (Xero, Sage, QuickBooks), e-commerce platforms (Shopify, WooCommerce, Magento), ERP systems, warehouse management tools, and logistics partners via REST APIs, webhooks, and EDI. Each integration takes roughly two to four weeks to build and test. We plan all integrations during discovery.
What about data security and compliance?
Every system includes UK GDPR compliance with encryption at rest and in transit, role-based access controls with field-level security, full audit trails with user attribution and timestamps, and automated backups. For regulated industries we build in batch traceability (pharma GMP), expiration tracking and HACCP support (food), COSHH logging (chemicals), or whatever your sector requires. UK data residency is standard.
How do you handle data migration from our current systems?
We budget three to six weeks for data migration depending on complexity. That covers requirements gathering, data mapping, cleaning and validation, ETL script development, and reconciliation testing. We handle product master data, supplier records, historical transactions (typically 12 to 24 months for forecasting), and reference data like units of measure, tax codes, and carrier rates.
Do you provide training for our team?
Yes. We deliver role-specific training tailored to each user group: warehouse and operations staff (receiving, picking, packing, barcode scanning), procurement (supplier management, purchase orders, approvals), planning and inventory (forecasting, replenishment, reporting), and finance (cost accounting, reconciliation). Training typically takes one to three days per role, plus ongoing support for four to eight weeks after launch.
When is off-the-shelf supply chain software good enough?
If you run a single warehouse with stable demand, fewer than 500 SKUs, under 20 suppliers, and no complex approval workflows or industry-specific compliance needs, a standard tool like ERPNext or Odoo Community may do the job. Custom development makes more sense when you have multi-site operations, bespoke procurement rules, regulated products, real-time integration requirements, or per-user licensing costs that are scaling faster than your revenue.
