GREVISION / BUSINESS SOFTWARE
POS software for the work at the till and behind it.
Hire Grevision to develop retail software around your sales and administration. We begin with the transaction: who records it, how products are found and which stock or payment records must change. Then we agree the screens, permissions and integrations needed for your shop. Market Te Lisi POS provides a concrete interface example to inspect before discussing your own requirements.

Map the workflow before choosing features
- 01
Find the product
Define your product identifiers, prices, variants and search process. Discuss how staff select an item and what information must be available at checkout, including any scanner or specialist device requirements.
- 02
Record the sale
Agree transaction states, permitted changes, payment records and the information needed on the sales document. Device, payment-provider and fiscal requirements are reviewed for the relevant business and country before a delivery scope is agreed.
- 03
Follow the stock
Describe how sales, purchases, returns and corrections affect stock. Identify who can make adjustments and what a manager needs to review. Reconciliation rules and reporting detail belong in the project requirements.
Define a useful first release
Checkout and product management
Discuss the catalogue, product search, price handling and staff workflow. We define the first version around the transactions your team actually completes, then separate later improvements from launch requirements.
Purchasing and operating records
Decide how deliveries, expenses and purchase records should be entered and reviewed. Where an accounting system already exists, we examine the available exchange format or interface before proposing an integration.
Access and traceability
Identify operators, managers and administrators. Agree permissions for changes, the records that must be retained and how a support request can be investigated without exposing unnecessary business data.
Operating conditions
Tell us about tills, computers, connectivity and existing peripherals. If you need offline operation, multiple locations or payment terminals, we assess their specific requirements and agree how they fit into the delivery plan.
Relevant work you can inspect
These portfolio examples show specific interfaces and documented capabilities. The scope of your application is agreed separately.

Market Te Lisi POS
Market Te Lisi POS includes checkout, product search, stock, purchases, expenses and accounting views, using Python, Django and JavaScript with a Windows client. The gallery shows a local demonstration of the real software with fictional grocery items. Inspect the checkout and administration screens to discuss which parts of your retail workflow need a similar interface.

Inspect project interfacesBring these questions to the first conversation
An existing spreadsheet, a sample record or a short demonstration can help explain the work. Start with non-sensitive examples; access to live systems is agreed when needed.
- Which sale, return and correction flows must the first release support?
- Which devices, payment services and existing accounting tools are involved?
- Who can change products, prices, stock and historical records?
- What data must move from your current system, and how will you check it?
Agree the delivery and the handover
The proposal defines the functions, responsibilities, review points and acceptance conditions. We discuss existing data, account ownership, hosting and third-party services before implementation. Migration, specialised devices, additional language versions and ongoing development enter the scope only when agreed.
Handover can include the agreed source access, deployment information, editing or operating guidance and a support plan. Ownership, confidentiality, payment, support hours and any warranty terms follow the project agreement. Send your requirements to discuss the scope, schedule and a negotiable project quote.
