DesignSilc

A global custom system application software company

DesignSilc is a global enterprise software development company with teams in Dhaka, Austin and the UK, building custom system application software — integrated enterprise systems similar to SAP that connect finance, procurement, inventory, production, sales and HR in one platform. Since 2015 we have delivered 1,000+ projects for clients in 38+ countries. Instead of paying high licence fees and reshaping your company around a global package, you get a system designed for your processes, approval chains, reports and local tax rules, from NBR VAT (Mushak) in Bangladesh to sales tax in the USA and VAT/MTD in the UK.

Already using SAP, Oracle, Microsoft Dynamics or another enterprise package? We also build custom applications and integrations around it — add-on modules, mobile apps, dashboards and data connections — so your core system keeps running while your team gets the tools it actually needs. Every enterprise system we build now ships with AI across its modules, from an approval copilot to plain-language analytics, plus an MCP server that lets approved AI assistants work with your data.

FAQ

Frequently asked questions

What is custom system application software?

System application software is the integrated enterprise software that runs a company's core operations, such as SAP or Oracle. Custom system application software is built specifically for one company. DesignSilc designs and builds these systems for businesses worldwide, connecting finance, procurement, inventory, production, sales and HR around your own processes.

Can DesignSilc build a system like SAP for my company?

Yes. DesignSilc builds SAP-style enterprise systems with integrated modules, role-based access, approval workflows and management reports. The difference is that the system is designed around your company rather than a global template, without per-user licence fees, and you own the software. We start with the most important modules and add more in phases.

Do you work with companies already using SAP or Oracle?

Yes. If your company already runs SAP, Oracle, Microsoft Dynamics or another ERP, DesignSilc builds custom add-on applications, mobile apps, dashboards and integrations that connect to it through APIs. This extends your existing system without replacing it. DesignSilc is an independent software company, not an official SAP or Oracle reseller.

How much does custom enterprise software cost?

The cost depends on the modules, number of users, integrations and rollout scope. DesignSilc gives a fixed quote after a free discovery call and process study, so the full price is clear before work starts, whether you are based in the USA, UK, Middle East or Bangladesh. Building in phases lets you start with the highest-value modules and spread the investment over time.

How long does it take to build an enterprise system?

A first release with core modules typically takes 3–6 months, depending on scope. DesignSilc delivers enterprise systems in phases with clear milestones, so departments can start using finished modules while the next ones are built. Data migration, user training and a support period are included in the plan.

What AI features does DesignSilc enterprise software include?

Each system can include an approval copilot that summarises requests against budgets and authority limits, plain-language analytics over your live data, invoice OCR with three-way matching to POs and goods receipts, variance explanations for each cost centre, rolling cash flow forecasts, slow-moving stock advice and predictive maintenance from plant sensors. A daily management summary can be written automatically each morning. We choose the modules where AI saves the most time first, then extend it as your teams get comfortable.

Can Claude, ChatGPT or our internal AI agents connect to the system?

Yes. The platform includes an MCP (Model Context Protocol) server that exposes finance, procurement, inventory and HR data as defined tools for Claude, ChatGPT, Cursor or your own agents. Every request runs under the user's own role and company codes, so an assistant can never see more than the person using it. Postings, purchase orders and other write actions are created as drafts that follow your normal approval chain, and each call is written to the audit trail. You can use a cloud AI model or host a private one on your own servers.
