Payment interfaces
Authorisation, capture, refunds and settlement events wired into the order record.
Software that keeps retail systems in conversation.
NAEEM MIRZA LTD builds and integrates the APIs, commerce platforms and operational software that retail, catalogue and mail-order businesses depend on. From Bradford, we work across the United Kingdom.
A Bradford software practice for digital commerce.
We design the connections between shops, catalogues, stock, payments and the customer record. The work sits in custom computer programming, computer systems design and IT consulting — always with live retail operations in mind.
Stock figures that stay honest between the warehouse and the storefront.

One new connection should not invent three new problems.
Bradford
API development and integration
The primary service: making separate systems exchange the data a trading operation actually needs.
Contracts that hold when orders start moving.
We specify, build and document interfaces between commerce platforms, payment gateways, inventory tools, CRM systems and the cloud services around them. The aim is a stable contract: what is sent, what is expected, and what happens when something fails.
Working approach
Map the systems first. Agree the events that matter — catalogue updates, stock changes, checkout, fulfilment, customer records. Then implement only the paths that trading depends on, with clear ownership on both sides of the interface.
Typical outputs
- API design and implementation
- Payment gateway integration
- Inventory and catalogue feeds
- CRM and order event wiring
- Handover notes for the teams who keep it
Catalogue feeds
Product data that can move between a store, a marketplace and a mail-order list without drifting.
Inventory events
Stock positions published so selling channels do not over-commit.
CRM movement
Customer and order history arriving where service teams actually look.
Marketplace connectors
Listings, orders and cancellations treated as one operational stream.
Cloud wiring
Hosted services joined with the same discipline as on-premise tools.
Access and identity
Credentials, roles and audit trails designed into the interface, not added later.
Operational handover
Enough documentation for the people who will live with the connection.
If the interface is vague, the shop floor pays for it.
Custom computer programming
Bespoke software where a packaged tool leaves a gap the operation cannot work around.
Web applications, internal tools and service layers written to the actual workflow.
Online store development
E-commerce solutions and digital commerce platforms built for catalogue, mail-order and mixed retail — not as a brochure, but as a selling system that can take payment and release stock.
Payment gateway integration
- Checkout connected to the order record
- Failed payments handled as operations, not as errors to hide
- Refund and settlement events returned to finance and fulfilment
- Room for more than one acquiring route where the business needs it
Marketplace platform development
Listings, sellers and orders treated as one catalogue with rules, not a pile of separate shops.
Cloud computing services
Hosted environments chosen and wired so the commerce stack can be changed without theatre.
Useful software is the version the operation can keep.
Selected work
Catalogue, stock and checkout on one contract
A mail-order and catalogue operation given a single path from product record to paid order.
Objective
Stop the website, the printed catalogue and the warehouse from describing different stock. Orders had to land in one place, with payment confirmed before picking began.
Approach
Define the product record once. Publish stock as an event, not as a nightly file that nobody trusted. Connect the payment gateway so fulfilment only starts on a successful capture.
Delivered
A working order path for catalogue and web channels, with inventory and payment treated as part of the same operational sequence.
Challenge
Channels had grown separately. Staff were reconciling stock by hand and delaying dispatch while payment status was checked.
Implementation
The interface had to survive incomplete product data and the awkward timing of mail-order peaks, not only a tidy demonstration path.
Delivery principle
Prefer a smaller set of reliable events over a wide integration that nobody can support on a Saturday.
Output type
API layer, payment gateway integration, inventory events and operational notes for the fulfilment team.
Inventory that can be asked
Stock positions published to the channels that sell them.
Store software with a live back
A shopfront that reads the same product record as the warehouse.
Marketplace listings without a second catalogue
One product record, several selling surfaces.
CRM events in the service queue
Order history arriving where people already work.
A marketplace catalogue with a single product record.
Sellers, listings and orders had accumulated as separate habits. The work was to make the catalogue the source, then let the marketplace, the store and fulfilment read from it.
Rules for price, availability and cancellation sit with the product, not in each channel’s private spreadsheet. The result is slower to start and much cheaper to keep.
Read the work
Not every system needs to be joined on day one.
NML · Bradford · BD9
Work that gains definition as it earns it.
We do not run a ceremonial timeline. Each pass adds only the information needed to make the next decision well.
Discover
What is sold, what must move, and which systems already hold the truth.
Map
People, platforms and data are placed in relation. Catalogue, stock, payment, CRM and fulfilment are named as they actually operate — including the unofficial workarounds.
Specify
A short contract: events, fields, failure behaviour.
Build
Custom programming, API work and platform configuration proceed against the contract, not against a sliding list of extras. Integrations with payment gateways, inventory tools and commerce platforms are implemented as operational paths, with logging that a human can read.
Verify
- Happy path from browse to paid order
- Stock conflict and oversell behaviour
- Failed payment and refund
- A channel going offline
- Handover the operating team can use
Hand over
Working software, the contract, and the few notes that prevent the next person from guessing.
Working principles
Name the source of truth before writing an interface. If catalogue, stock and customer live in three places, the API will only spread the confusion faster.
Prefer events the business already understands — order placed, stock reserved, payment captured — over abstract resource models that look tidy and fail in peak week.
Expertise
API development and integration, e-commerce solutions, online store development, retail software, marketplace platforms, web applications, mobile commerce, inventory systems, payment gateways, CRM, cloud computing and IT consulting.
Delivery considerations
Retail software is judged on Saturday afternoon, not in a staging environment. Mail-order and catalogue businesses still run on peaks, incomplete product data and staff who will not read a forty-page specification. Integrations have to degrade in a way a human can act on.
We keep the surface small: the connections that trading depends on, documented well enough to change later. Custom computer programming is used where a package leaves a real gap, not as a default.
Where this sits
The practice covers computer systems design, custom programming and computer-related consulting, alongside digital commerce work for retail trade, catalogue and mail-order operations, and miscellaneous retail.
United Kingdom
Work is delivered from Bradford for organisations across the UK. Conversations start in English, with the operational detail of the shop, the warehouse or the catalogue — not with a generic transformation programme.
Join less. Mean it more.
NAEEM MIRZA LTD
Software for the systems that sit behind a sale.
A company that treats retail software as operations, not decoration.
NAEEM MIRZA LTD is based at 4 Toller Grove, Bradford, BD9 5NP. We provide API development and integration as the centre of the practice, with e-commerce, retail software, marketplace platforms and IT consulting around it.
The company works where computer systems design meets the realities of retail trade: online stores, catalogue and mail-order houses, inventory, payments and the customer record. Custom programming is used when the operation needs a specific path. Packaged platforms are used when they already hold the truth.
Engagements are practical. We would rather leave a short, durable interface than a landscape of tools that need a specialist to interpret. Cloud services, CRM connections and mobile commerce applications are included when they serve that same operational picture.
