Most production scheduling problems do not start as software problems. They start when the spreadsheet that used to work stops keeping up: scheduling takes days instead of hours, a missed material delay turns into a missed delivery, and nobody can see actual progress against the plan until it is too late to react. At that point you need a real system. The question is whether an off-the-shelf tool will fit the way you actually make things, or fight it.
At ByteGears we build production scheduling and planning software around your routings, your constraints and your shop floor. We are a small London consultancy, and we mostly work with UK manufacturers in the 25 to 200 employee range, the businesses caught between outgrowing spreadsheets and not being able to justify a six-figure enterprise APS.
Why off-the-shelf production scheduling software falls short
The market splits into two awkward halves. At the lower end, cloud MRP tools like MRPeasy, Katana and Fishbowl get you off spreadsheets quickly. At the top end, enterprise APS platforms such as Siemens Opcenter and PlanetTogether offer genuine finite capacity optimisation, but at enterprise cost and on a nine to eighteen month implementation. Plenty of UK manufacturers do not fit cleanly into either.
The common pinch points:
- Inventory-first scheduling. Tools built around stock levels do not run proper MRP logic for multi-level BOMs, and they struggle with multi-step routing and rework loops.
- No real finite capacity. Many mid-market tools schedule against time, not against actual machine and labour constraints, so the plan looks fine and the shop floor does not.
- Per-user pricing that punishes growth. SaaS at roughly £40 to £120 per user per month adds up fast. A twenty-person planning and supervisor team can cost well into five figures a year, and rises with every hire.
- Fixed workflows. Approval thresholds, expedite rules and product-family setup logic often cannot be changed to match how you work, so people work around the tool.
- Fragile integration. Connections to an existing ERP, accounting system or shop floor equipment are often batch-only or weak, and manual re-keying quietly survives the rollout.
- Hidden costs after signing. Annual escalation clauses, extra-user licences, paid-for APS or forecasting modules, premium support and migration help are rarely in the headline price.
- Vendor lock-in. The data model is not portable, so leaving later is slow and expensive.
The real cost is rarely the licence on its own. It is the planner time spent compensating for what the tool cannot do, and the orders that slip while the schedule and reality drift apart.
What ByteGears builds instead
We build a scheduling system that models your business rather than a generic manufacturer. A few things that tend to set our work apart:
Built around your routings and constraints
Engineer-to-order, configure-to-order and high-mix job shops usually have routing, setup and sequencing rules that generic MRP cannot represent. We model your constraints directly, including product-family changeover times, labour certifications and shift-specific capacity, instead of forcing your process into a vendor’s template.
Finite capacity, focused on your bottleneck
Generic APS tries to optimise every constraint at once and needs a specialist to run it. We can focus the scheduling logic on the constraint that actually limits your throughput, whether that is one critical machine or labour availability on a single shift. Where the maths warrants it, we build on a proven open-source constraint solver rather than reinventing it, so you get the optimisation without the enterprise overhead.
Integration without middleware
We build the integration logic into the system itself, so you can skip expensive middleware. Modern cloud ERP and accounting tools connect cleanly via API; older on-premise ERP and real-time machine data take more work, and we scope that honestly up front.
One-off cost, no per-seat fee
You own the software outright. There is no monthly per-user charge, no annual escalation clause and no module you have to buy again later. As you grow, cost scales with infrastructure, not with headcount.
UK compliance from the start
GDPR, role-based access, audit trails and UK or EU data residency are part of the design, not a premium add-on. ISO 9001 traceability and HACCP lot tracking are built in where the sector needs them.
Local support
Our team is based in London. You get answers in your working hours, in plain English, without offshore timezone gaps.
Features we typically build
Most manufacturers need a similar core, then a handful of features specific to their industry. A custom build usually includes some mix of the following:
- Bill of Materials management with multi-level structures, revisions and engineering change history
- Work order lifecycle tracking, from sales order through release, in-progress and completion
- Gantt chart scheduling with drag-and-drop rescheduling
- Finite capacity planning that respects real machine and labour limits, with bottleneck identification
- Material requirements planning that explodes BOMs into net material needs and purchase orders
- Real-time shop floor visibility of orders, work in progress and resource use
- What-if scenario modelling for rush orders, machine downtime or material delays before you commit
- Mobile or tablet shop floor reporting, with barcode scanning and lot traceability
- Exception alerts for late orders, material shortages and capacity overload
- KPI dashboards built around your numbers: on-time delivery, utilisation, WIP days, setup time
- Role-based access, change tracking and approval workflows that match your rules
- Multi-site coordination with location-specific calendars and constraints
- Audit trail with full change history for ISO 9001 and customer audits
How we deliver the software
We work in four phases:
- Discovery and planning (2 to 4 weeks). We map your current process, run a requirements workshop with the planners and supervisors who will use the system, and assess the state of your BOM and routing data, which is usually the biggest risk to a project like this.
- Development (roughly 8 to 16 weeks). Agile sprints with regular demos, UI work focused on shop floor adoption, and integration with your existing systems.
- Testing and deployment (2 to 4 weeks). System and user acceptance testing, then a pilot that validates schedule accuracy against reality before go-live, usually running in parallel with the old process.
- Training and support (ongoing). Role-based training, planners needing the most and shop floor and purchasing staff less, plus a UK-based support arrangement.
A focused first release usually lands in 4 to 6 months. We deliver a working core first, then add finite capacity optimisation, what-if modelling, a mobile app or multi-site planning as a later phase, only where there is a clear business case.
What it costs
Custom development is an upfront project cost, so it is worth being plain about the trade-off:
- SaaS looks cheaper on day one and gets more expensive over time, through per-user growth, annual escalation and paid add-on modules. A custom build is a one-off cost with no per-seat fee.
- For a UK mid-market manufacturer, a focused first release covering BOM and work order management, Gantt scheduling and one ERP or accounting integration is a smaller project than a full build with finite capacity optimisation, a mobile app and multi-site planning. We scope to your priorities so you are not paying for capability you will not use.
- You own the software, so there is no vendor lock-in, no forced upgrades and no contract renegotiation to add a feature.
- We can quote fixed-price or time-and-materials, whichever suits the project.
We will not pretend custom always wins. If your product mix is stable, your demand predictable and you run a single site, an off-the-shelf tool may be the sensible answer, and we will tell you so. At the free consultation you get a real estimate against your requirements, not a generic figure.
Industries we build production scheduling software for
The same underlying system adapts to very different production environments, and the scheduling logic changes with the work:
- Food and beverage. Batch and campaign scheduling, allergen and hazard segregation, shelf-life and lot traceability for HACCP.
- Engineer-to-order and heavy equipment. Project-style scheduling, critical path management and long supplier lead times.
- Job shops and contract manufacturing. High-mix, low-volume work, job sequencing to minimise setup, and shared resources across concurrent jobs.
- Automotive suppliers. Pull-based scheduling from customer demand, just-in-time delivery and IATF 16949 quality requirements.
- Electronics and machinery. Complex multi-level BOMs, frequent engineering changes and assembly-line capacity balanced against component availability.
- Aerospace and medical devices. Strict quality stages, sterilisation or lot documentation, and long retention requirements.
- Furniture and configure-to-order. Variable production times per order and customer-visible delivery status.
- Plastics, packaging and metal fabrication. Mould or tooling changeovers, material usage and machine-shop loading.
Custom development means the industry-specific detail that off-the-shelf tools tend to miss, from material traceability to certification management, is built in rather than worked around.
Common Questions About Custom Production Scheduling Software for UK Manufacturers
How does a custom build compare to MRPeasy, Katana or an enterprise APS on cost?
Cloud MRP tools usually charge per user per month, so the cost rises every time you add a planner or scheduler. Enterprise APS platforms carry large annual licences plus a long, expensive implementation. A custom build is a one-off project cost with no per-seat fee, so the comparison improves the longer you run it and the more people use it. For most UK mid-market manufacturers, custom starts to look competitive against three to five years of subscriptions once team size and add-on modules are factored in. We give you a real estimate at consultation rather than a generic figure.
Do we actually need bespoke software, or is an off-the-shelf tool fine?
If you have a stable product mix, few engineering changes, a single site and predictable demand, an off-the-shelf MRP tool is often enough and we will say so. Custom tends to pay off when you have engineer-to-order or configure-to-order products, complex multi-step routings with rework loops, unusual constraint rules such as product-family setup times or labour certifications, multi-site dependencies, or a legacy ERP and shop floor systems that generic tools integrate with poorly.
What's the typical development timeline?
A focused first release usually takes 4 to 6 months, covering BOM and work order management, Gantt scheduling, one accounting or ERP integration and basic shop floor tracking. Finite capacity optimisation, what-if modelling, a mobile shop floor app and multi-site planning are normally added in a later phase. We aim to get a working core into your hands before the full build is finished.
Can you integrate with our existing ERP and shop floor systems?
Yes. Modern cloud accounting and ERP systems such as Xero and QuickBooks Online integrate cleanly via REST API. Older on-premise ERP like SAP or Infor takes more work, and real-time machine or IoT data more again, but it is all achievable. We build the integration logic directly rather than relying on costly middleware, and we map data flows up front so purchase orders, labour hours and order status do not need re-keying.
What about data security and compliance?
We build with UK GDPR in mind, including role-based access so planners do not see payroll data, audit trails with full change history, encryption at rest and in transit, and UK or EU data residency. Where it applies we also support ISO 9001 traceability, lot tracking for HACCP in food and beverage, and retention rules for production and quality records.
What usually goes wrong with these projects, and how do you avoid it?
The most common failure is poor BOM and routing data: if the underlying data is wrong, the schedule is worthless. We validate data quality and schedule accuracy during a pilot phase before go-live. We also avoid embedding every existing manual workaround, which makes systems unmaintainable, and we plan integrations early so the new tool does not sit siloed next to your ERP.
Do you provide training and ongoing support?
Yes. Training is included and tailored by role, with planners needing the most time and shop floor and purchasing staff less. After launch we offer flexible support, from ad-hoc help to a managed arrangement, so your team can request changes as business rules evolve.
