Understand
Discuss goals, audiences and constraints to define a useful scope.
Ecommerce development for catalogues, checkout and order operations
Build around product variants, inventory, payment and fulfilment, testing successful, failed and repeated order events before opening sales.
WHO IT’S FOR
What should the website help your business do?
Businesses owning a sales channel with a team responsible for products, orders and customer support.
- Prices or stock differ from their source system
- Orders are released from a QR or screenshot without confirmed payment
- Staff cannot identify and resolve failed or repeated transactions
SCOPE & SOLUTION
The development scope
- 01
Categories, products, variants and inventory source
- 02
Cart/checkout totals, shipping and conditions
- 03
Server-side payment confirmation
- 04
Order and fulfilment states within the agreed scope
- 05
Product/order administration and team documentation
ILLUSTRATIVE WORKFLOW
Example: product → checkout → pending → confirmed → fulfilment
Use order and provider payment references. Validate events and expected amounts before inventory or fulfilment actions. Late payments, cancellations and refunds need explicit states understood by the team.
An illustrative scope example; inclusion is agreed for each project.
ACCEPTANCE
Agree acceptance before development
- Test unavailable variants and quantity-dependent totals
- Test success, failure, duplicate and out-of-order payment events
- Provide order lookup, supported refund actions and history

PROJECT INVESTMENT
Project and ongoing costs
Scope follows catalogue size, variants, stock systems, payment methods, shipping, migration and existing integrations. External and ongoing costs are separated in the proposal.
The proposal identifies templates, languages, content, inclusions, integrations and post-launch responsibilities before work begins.
- Payment provider, hosting and transactional email fees
- Chosen inventory, shipping or accounting integrations
- Catalogue updates and security maintenance
Questions before commissioning
Standard platform or custom ecommerce?
Use an existing platform when it matches the workflow. Custom development is justified by meaningful product, pricing or integration requirements.
Can you integrate PromptPay?
We assess the payment provider and supported APIs, including confirmation, repeated events and supported refund workflows.
Have a website or workflow to improve?
Share the current site, example data and next steps for your team. We can identify a useful first release and future additions.
