Stock, order, and purchasing records disagree across systems.
Custom ERP development, migration & integration
Bring inventory, purchasing, sales, orders, approvals, and reporting into a connected operating system. Operithm develops custom ERP modules and integrates existing business software, with phased delivery, data migration, permissions, and team handover scoped around your workflows.
Your delivery path
- 01
Map the operation
Observe real records, business rules, dependencies, and exception handling.
- 02
Define a module
Agree shared data, roles, user actions, and acceptance criteria for a manageable phase.
- 03
Build and reconcile
Implement the workflow and validate data movement with representative records.
- 04
Pilot and adopt
Train users, observe a limited rollout, and agree cutover and expansion criteria.
Scoped around your business. Delivered worldwide.
Where this service helps
For growing businesses, retailers, wholesalers, and operational teams managing important records across spreadsheets and disconnected tools. Start with a bounded process before expanding the ERP.
Approvals are managed in messages with no clear audit trail.
Sales and operations repeatedly enter the same information.
Managers assemble reports manually from several sources.
An existing ERP needs integrations or a custom operational module.
A software change requires a controlled migration and staff adoption plan.
Who this is for
Business owners, operations leaders, and department teams that need shared records and a clearer way to manage work.
Inventory to purchasing
Connect stock movements, replenishment requests, supplier orders, and receiving records.
Sales to fulfillment
Carry an approved customer order into the operational steps and reporting behind delivery.
Department approvals
Replace message-based approvals with named roles, visible state, and review history.
Service capabilities
01
Inventory and warehouse workflows
Products, stock movements, locations, adjustments, and replenishment requirements mapped to your operational model.
02
Purchasing and suppliers
Purchase requests, approval stages, supplier records, orders, and receiving workflows with clear ownership.
03
Sales and order management
Connect customer records, quotations, order states, fulfillment, and relevant payment or billing integrations.
04
Roles and approvals
Define who can view, change, approve, and export records, with histories appropriate to the workflow.
05
Dashboards and reporting
Operational queues, exceptions, and reports sourced from agreed records rather than repeated spreadsheet consolidation.
06
Migration and integration
Map source data, reconcile imports, plan cutover, and connect existing CRM, commerce, or accounting tools through available interfaces.
What you receive
A defined delivery package, not an open-ended promise.
We agree the exact deliverables, acceptance criteria, and responsibilities in your proposal. A typical scope includes:
- 01Current-state and target workflow map
- 02Data model, permissions, and approval rules
- 03Implemented modules and operational views
- 04Migration and integration checks where required
- 05Operator training, documentation, and handover
How we deliver

Tools and integration considerations
The technical approach follows your requirements, access, and operating model. Relevant components can include:
- Custom ERP modules
- Inventory and order records
- CRM and accounting APIs
- Migration utilities
- Role-based approval workflows
Build boundary
Agree the right foundation, project responsibilities, and operating requirements before implementation.
Discover
Map current workflows, record ownership, business rules, and existing software before selecting the approach.
Phase
Release a useful module or department workflow first, with acceptance criteria for expansion.
Migrate
Agree data cleansing, reconciliation, pilot use, rollback, and the point at which records move to the new system.
Adopt
Train operators, document responsibilities, and scope ongoing support. Existing-platform customization is assessed individually.
Planning your project
Start with an audit or discovery where needed, agree an implementation scope, and add ongoing improvements or care when useful. Pricing and timing reflect the agreed work; third-party charges are identified separately.
What shapes the estimate
- Modules, departments, and approval complexity
- Data quality and legacy-system access
- Integration, migration, training, and rollout scope
Can we start with one ERP module?
Yes. A phased release can focus on inventory, purchasing, approvals, or another bounded workflow, with shared records and dependencies planned for later expansion.
Can you work with an existing ERP?
We assess its APIs, permissions, data model, and extension options. Integration or a custom module may be sufficient. Platform-specific implementation and customization require an individual technical assessment.
How is data migration handled?
The migration scope covers field mapping, cleansing responsibilities, test imports, reconciliation, pilot use, and cutover. Rollback and legacy-system access are planned before switching workflows.
Will staff receive training?
An agreed implementation includes documentation and operator handover. Training sessions, department rollout, and ongoing support are defined in the proposal.
Can you work with our business outside the UK or Bangladesh?
Yes. We offer remote delivery worldwide, including North and South America, Europe, Asia, Africa, and Oceania. We agree meeting overlap, communication channels, and milestones around the project.
What should we prepare before requesting a proposal?
Share your business goal, intended users, current situation, required integrations, and timing. Budget context helps identify a practical first scope. A detailed technical specification is not required to start.
How are scope, handover, and ongoing support agreed?
The proposal identifies deliverables, assumptions, approval responsibilities, account and source ownership, and any ongoing costs. Support hours, maintenance, and future improvements are scoped explicitly.
