Custom ERP & Business Software.
We build software around your existing processes, so your business does not have to change its workflow to fit off-the-shelf software. Custom ERP, digitised forms, workflow automation and legacy integration for retail and manufacturing businesses, with AI added where it pays.
01 / Scope
What We Build
Every system improves operational visibility, accountability and process control, and is deployed, monitored and maintained after go-live.
S02
Digitising manual forms
Paper registers, Excel sheets and WhatsApp approvals turned into structured, searchable apps with an audit trail.
S03
SOP implementation
Standard operating procedures built into the software as steps, checks and approvals, so the process is followed by default.
S04
Workflow automation
Data entry, document processing and system-to-system sync that run around the clock without a person in the loop.
S05
Legacy integration and retrofitting
Older applications connected, modernised or extended rather than thrown away.
S06
AI layer on SAP B1 or Tally
Alerts, reports, forecasts and private AI assistants that work from the data already in your ERP.
02 / Fit
Custom or Off-the-Shelf?
If an off-the-shelf ERP such as SAP Business One or Tally already fits most of your process, keep it. We add the missing pieces on top: integrations, automations, dashboards and AI.
Custom software makes sense when your process is what makes you competitive, when the gaps are being filled by spreadsheets and phone calls, or when several systems have to work as one. That decision is made after we have seen your operation, not before.

04 / FAQ
Frequently Asked Questions
Does Deda Systems build custom ERP software?
Yes. Deda Systems builds custom ERP and business software for retail and manufacturing companies, including inventory, purchase, production, sales and finance modules, digitised forms, SOP workflows and integrations with existing systems.
Should we build a custom ERP or use SAP Business One or Tally?
If an off-the-shelf ERP fits most of your process, keep it and add an integration and AI layer on top. Custom software makes sense where your process is a competitive advantage or where the gaps are filled by spreadsheets and manual work. Deda Systems recommends one or the other after an on-site visit.
How long does a custom ERP project take?
A free 30-minute discovery call comes first. We then spend two to four days on site before writing a proposal. Scope, timeline and price are fixed before any code is written. You see a first working demo on your own data in week 1, and a first scope typically reaches production in weeks 6 to 12. Larger ERPs are delivered module by module.
How is a project priced?
Scope, timeline and price are fixed and agreed before any code is written, so there are no change-order surprises. The discovery call is free.
Will we be locked in?
No. The system is deployed on your infrastructure or your cloud, your data stays yours, and your team is trained to operate it. Retainer support is available for new features and model retraining.
Tell Us What’s Slowing You Down.
Thirty minutes on a call is usually enough to tell whether there is something worth building together. We respond within one business day.
