Do you need POS or ERP? Start with the operating cycle, not the software label
Both products may show products, sales, and reports, but they do not serve the same operation. This framework identifies the starting point and when a business needs an integration review instead of another screen.

Short answer
Choose POS for restaurant orders and ERP for the retail and inventory cycle
If the core operation starts with a customer order moving through cashier, table, kitchen, pickup, or delivery, start with POS. If it starts with a product, unit, warehouse, supplier, purchase, sale, and accounts, start with ERP. Branches and reports in both products do not make them interchangeable.
Operating-scope comparison
This table describes scopes evidenced in Orpinn product pages and code paths; it is not a universal rule for every system in the market.
| Decision criterion | Orpinn POS | Orpinn ERP |
|---|---|---|
| Starting context | Restaurant or cafe order, service type, table, or customer. | Product, unit, warehouse, branch, and opening balance. |
| Core movement | Add items, route preparation, collect payment, print, and track order state. | Purchase, receive, sell, return, waste, voucher, and balance movement. |
| Front-line operation | Cashier, floor, takeaway, delivery, and electronic menu. | Entry, stock, purchasing, sales, accounts, and report views. |
| Setup data | Products, tables, outlets, printers, and permissions. | Products, units, warehouses, branches, balances, and accounts. |
| Boundaries to verify | Device compatibility, printing, reception, and integrations. | Migration, barcode or scale devices, integrations, and tax requirements. |
Map the operation before comparing features
Write down the first event, the final result, and every role touching the data. A long feature list does not help when product ownership or the next action is unclear.
- Restaurant: who creates the order, where does it arrive, when does it print, and who changes its state?
- Retail: who defines the product and unit, where does stock enter, and which document changes the balance?
- Branches: which data is shared and which data stays inside a branch or permission boundary?
When is POS or ERP alone not enough?
A business may have a restaurant and a central warehouse or multiple sales channels. Do not assume every record is shared automatically; define the source of truth, integration contracts, and synchronization path.
- Choose the owner of the product catalog, prices, and units.
- Define whether stock is branch-operational, central, or both through an explicit contract.
- Test one full workflow from creation to report before expanding the integration.
Inputs to send before pricing or migration
These inputs make scope concrete and avoid a generic price or duration that does not fit the operation.
- Activity type, branch and user counts, and current devices.
- Product or menu-item count, units of measure, and current data sources.
- Required order or document types, reports, and approvals.
- Any device or integration with its model, protocol, or available documentation.
Questions that identify the starting point
Does inventory inside POS make it an ERP?
Not necessarily. Restaurant operational inventory may serve orders and ingredients, while ERP covers a broader trade cycle of units, warehouses, purchasing, accounts, and documents. Compare the required workflow, not the module label.
Can one business need both products?
Yes as a possible architecture, but comprehensive integration should not be assumed. Sources of truth, branches, shared data, and synchronization must be defined and tested in written scope.
Is there a fixed package or migration duration?
No public fixed package or duration is documented. Branch count, data volume and quality, devices, and integrations determine the proposal and migration plan.
