Manufacturing SMEs and industrial companies
Factories in carpet, machinery, textile or food production running work orders, recipes, scrap and cost tracking in Excel, and wanting to close the gap between production and accounting.
CUSTOM SOFTWARE · ERP
Custom ERP Software
ERP software designed around your processes, bringing your entire operation — from production to finance — onto a single backbone. Where the off-the-shelf package falls short, we build a system that fits your factory exactly.
ERP (Enterprise Resource Planning) is software that unifies a company's production, inventory, purchasing, costing, finance, sales and shipping processes on a single data backbone. With one source of truth, every department sees the same stock, the same cost and the same order status; information flows inside the system, not between spreadsheets. Set up properly, ERP is not an accounting tool — it is the factory's real-time decision centre.
Off-the-shelf ERP packages are a quick start for standard processes; but in carpet, machinery, textile or food production, recipes, scrap rates, subcontracting relationships and cost calculations rarely fit the package. At that point companies either give up on the software and go back to Excel, or force their processes to fit the tool. Custom ERP software reverses that balance: the software adapts to the way you work, not the other way round.
At Pan Innovation House, rather than writing an ERP from scratch as a monolith, we build it as an API-first, modular architecture that talks to your existing systems. Accounting can stay in Logo (a widely used Turkish ERP), SAP or Mikro, while we develop the production, planning and costing layer specifically for you. The source code we write and your data are handed over to you as defined in the contract; third-party and open-source components remain subject to their own licences. Deliveries go through a review step before they go live, and the maintenance scope and response times are defined in the contract.
Who is it for?
Custom ERP Software: who it is for
Businesses that don't fit the off-the-shelf package
Companies using Logo or a similar ERP while running half their processes outside it. Firms whose subcontracting, tiered costing or bespoke planning needs push past the package's limits.
Exporters and multi-site companies
Businesses that need shipping, customs documentation, currency-based costing and multi-warehouse tracking in one system, and want to see the export operation on the same backbone as sales and production.
Growing companies putting their systems in order
Management teams finding that as order volumes grow, tracking stock, planning and cash flow by eye has become impossible — and wanting to move to a data-driven, scalable foundation.
What we build
Custom ERP Software: what we deliver
Production and work order management
Work orders opened against sales orders or stock forecasts, operation and station tracking, bill-of-materials (BOM) based production, shift and scrap recording. Data entered on the shop floor feeds planning in real time.
MRP and production planning
Material requirements planning calculates which raw material is needed, when and in what quantity; purchasing suggestions, capacity and delivery scheduling. Which order is waiting on what is visible on a single screen.
Inventory, warehouse and batch tracking
Multi-warehouse stock, minimum/critical level alerts, batch and serial number traceability, goods in/out via barcode/RFID. The gap between actual stock and recorded stock closes.
Costing and profitability
True production cost including raw materials, labour and overheads; profitability by order, product or customer. You see in hard numbers which jobs actually make money.
Finance, accounts and cash flow
Customer/supplier accounts, receivables and payments, cheques and notes, banking and cash flow projections. E-invoices and e-dispatch notes are managed from within the ERP through your private integrator's API (an integrator approved by GİB, the Turkish Revenue Administration), or through direct GİB integration where you are authorised for it.
Shipping and order management
The flow from sales order to dispatch, partial deliveries, dispatch notes and customs documentation; currency and delivery-date tracking for exports. The status of a customer order is visible at every stage.
Logo/SAP bridge and reporting
Two-way integration with your existing accounting system through the route its version supports (API, service layer or an approved import); role-based permissions, audit trails and live management dashboards. Duplicate data entry disappears.

Process
How we move from discovery to go-live
- 01
Discovery and process mapping
We observe your production, inventory and costing processes on site, mapping the current flow and the real bottlenecks. At this stage we answer the question clearly: off-the-shelf package or custom build?
- 02
Data model and architecture
We design a data model fitted to your recipes, warehouses, accounts and cost structure, on an API-first, modular architecture. The scope of the Logo/SAP bridge and other integrations is fixed here.
- 03
MVP and priority module
We take the module that creates the most critical value (usually production/work orders or inventory) live first. With an early working piece you see the value, and we prioritise the rest accordingly.
- 04
Integration and data migration
We connect the accounting system, e-invoicing and, where needed, shop-floor devices, and migrate your legacy stock and account data after cleansing it. Every sprint ends with a visible deliverable that has gone through a review step before release.
- 05
Go-live, training and maintenance
We go live in stages without stopping production, and train the users. The system then keeps evolving under a maintenance relationship, defined in the contract, covering monitoring, security and further development.
Frequently asked questions
Common questions about Custom ERP Software
Off-the-shelf ERP or custom ERP — which is the right choice?
If your processes are standard and fit the package, an off-the-shelf ERP is a fast and sensible start. But if your recipes, scrap, subcontracting or costing are your competitive edge and no package truly fits, custom development can be the more flexible route; total cost depends on scope, number of users and maintenance period, and we compare both options with you during discovery. In the first call we compare both; very often the right answer is an off-the-shelf package for accounting and a custom layer for production.
How are timeline and cost determined?
Timeline and cost depend mainly on the modules in scope, the number of users and sites, the depth of accounting and e-document integration, data migration and the state of your bills of materials. A single module can take a few weeks; a comprehensive ERP can take several months. Because we work iteratively rather than to a fixed scope, cost is finalised after discovery; we do not quote unrealistic figures — the price takes shape with the scope. By taking the most critical module (the MVP) live first, you see value early and manage the budget step by step.
Will the source code and data belong to us?
Yes. The source code we write and your data are handed over to you as defined in the contract; third-party and open-source components remain subject to their own licences. Technical documentation and the database are handed over too; you can carry on with another team if you wish.
Will it integrate with our existing Logo/SAP and accounting system?
In most cases, yes. A two-way connection with systems such as Logo (a widely used Turkish ERP), SAP or Mikro is usually possible; accounting stays where it is while production and costing run in the custom ERP. The custom layer connects to your ERP through the routes its vendor supports (API, service layer or an approved import); it does not write directly into the ERP's database tables. The route depends on the version and licence and is agreed in writing during discovery. E-invoices go through your private integrator's API, or through direct GİB integration where you are authorised for it. In production, barcode/RFID is a method we often use. Eliminating duplicate data entry is a core goal.
Can we switch over without stopping production?
Yes. We bring the system live in stages rather than all at once; one module or one department goes first, and the old method runs in parallel for a while. Data migration and user training follow that plan, so the risk of interrupting production is reduced.
Is there maintenance and support after go-live?
There is. We offer monthly maintenance packages, with scope and response times defined in the contract, covering monitoring, security updates, bug fixes and new feature development. ERP is a living product; as your business processes change, the system evolves with you.

For businesses in Gaziantep
Production Tracking & MES
We develop a manufacturing execution system built for your factory — making the shop floor visible in real time, from work orders to OEE, scrap to shifts, running on a PLC/SCADA bridge and shop-floor terminals.
Details →IoT & Embedded Systems
We design the whole chain from sensor to cloud: device firmware, MQTT-based telemetry, edge processing and a remote monitoring panel. Your machines, production line and field equipment come together in a single data stream — and the source code we write is handed over to you.
Details →Predictive Maintenance
We collect a machine's vibration, temperature, current and cycle data, learn its normal operating signature, and catch deviations from that signature before failure occurs. An alert becomes a maintenance work order; the machine's history and the parts used accumulate in the same record.
Details →Computer Vision Quality Control
We build camera-based visual inspection on the production line: surface defects, colour and shade variation, missing parts, label verification and dimensional checks. The work does not begin as a software installation — it begins with feasibility and sample testing.
Details →Demand Forecasting and Production Planning Intelligence
We generate demand forecasts from order history, seasonality and stock data, and link that forecast to your production and purchasing plans. We sequence work under capacity constraints, calculate safety stock and measure how accurate the forecast actually was.
Details →Timekeeping and Incentive Management
We build a system that collects labour data from the shift plan to the time-and-attendance terminal, from overtime to piece-rate incentives, and prepares the file that goes to payroll matched against production records. Who has earned what is visible clearly enough that objections become unnecessary.
