What we build
What does a ecommerce software development company build?

Storefront - 02
B2B commerce portals
Account hierarchies, contract pricing, quotes, purchase approvals, reordering, and credit terms — the parts consumer platforms handle badly.
B2B - 03
Marketplace platforms
Seller onboarding, catalog controls, order splitting, commissions, and payouts with the ledger discipline multi-party money requires.
Marketplace - 04
Order and inventory orchestration
Distributed availability, sourcing rules, split shipments, returns, and exception handling across warehouses and 3PLs.
Operations - 05
Product data pipelines
PIM integration, enrichment, syndication, and image pipelines that keep catalogs consistent across every channel.
Catalog - 06
Commerce AI agents
Merchandising and description generation, support answering from order data, returns triage, and inventory exception investigation.

Requirements
Which requirements shape ecommerce software development?
Commerce systems are judged on speed, findability, and correctness: pages must pass Core Web Vitals and render content server-side for crawlers, availability and pricing must be right in real time, checkout must be resilient, and accessibility failures cost both customers and legal exposure.
| Requirement | What it means here | How FISTA builds to it |
|---|---|---|
| Performance | Slow pages lose revenue and rank. | Server-rendered storefront, image and font discipline, edge caching, and a performance budget enforced in CI against real device profiles. |
| Search visibility | Product and category pages must be crawlable and richly structured. | Server-side rendering of all indexable content, canonical and pagination discipline, Product and Offer structured data, and clean faceted-navigation rules. |
| Inventory accuracy | Overselling and phantom stock destroy margin and trust. | Event-driven inventory sync, reservation on cart or checkout per your policy, and reconciliation jobs against the system of record. |
| Checkout resilience | Payment and tax provider failures must not lose orders. | Idempotent order creation, provider failover, queued retries, and an order state machine that can always be resumed. |
| Accessibility | Storefronts must be usable with assistive technology. | WCAG 2.1 AA acceptance criteria, keyboard and screen-reader testing in CI, and accessible checkout and form error handling. |
Where AI fits
Where do AI agents fit in ecommerce?
AI agents fit commerce where catalog and customer volume exceed team capacity: product content generation, support answering from order data, returns and dispute triage, inventory exception investigation, and merchandising analysis. Agents draft and recommend; pricing and policy changes stay with your team.
- 01
Product content agent
Generates descriptions, attributes, and metadata from supplier data and images, with brand-voice rules and human approval before publishing.
- 02
Customer support agent
Answers order, shipping, and returns questions from read-only order data, escalating refunds and exceptions to a human.
- 03
Returns triage agent
Classifies return reasons, checks policy eligibility, and proposes the disposition for an operations reviewer.
- 04
Inventory exception agent
Investigates mismatches between platform, ERP, and 3PL counts and proposes the correcting adjustment for approval.
- 05
Merchandising analyst agent
Surfaces slow movers, margin leaks, and search-with-no-results patterns with the underlying data attached for the merchandiser.
Cost and timeline
How much does ecommerce software development cost, and how long does it take?
Cost is driven by catalog complexity, integration count, B2B pricing rules, and marketplace money flows; timeline by data migration and third-party onboarding. FISTA does not quote blind: the scoping call returns a specification, an integration map, and a phased estimate.
Integrations, not pages, drive commerce budgets. A storefront over one platform is straightforward; the same storefront reconciling inventory across an ERP, two warehouses, and a 3PL, with tax and carrier services in the path, is a different scope. FISTA maps every integration in discovery and prices them individually so you can stage them.
Migration deserves its own line. Catalog, customer, order history, and URL structure all have to move without losing search rankings. FISTA plans redirects, canonical continuity, and content parity before launch, because a fast new storefront that drops organic traffic is a net loss.
Send the scope you have, even if it is a paragraph. You get a written brief, an architecture sketch, and a phased estimate before any commitment.

How does FISTA deliver an industry software project?
FISTA delivers in four gated phases: a discovery sprint that produces the specification and integration map, an architecture and compliance design that names every control, iterative builds demoed weekly on your environment, and a verified release with runbooks, monitoring, and a handover or a managed operations option.
- 1
Discover and specify
Stakeholder interviews, system inventory, data classification, and a written specification with acceptance criteria and a phased plan.
OutputSpecification, integration map, estimate
- 2
Design for compliance
Architecture, data model, security controls, and the evidence plan for any audit, agreed before the first sprint.
OutputArchitecture decision record, control matrix
- 3
Build and demonstrate
Two-week sprints with automated tests, contract tests on integrations, and a demo on your environment every week.
OutputWorking increments in your repository
- 4
Verify and operate
Load, security, and acceptance testing against the spec; release with runbooks, dashboards, and alerting; optional managed operations.
OutputVerified release, runbooks, SLOs
Why FISTA
Why choose FISTA Solutions for ecommerce software development?
FISTA builds commerce on server-rendered architecture with performance and search treated as engineering requirements, not marketing wishes. Money flows get ledger discipline, integrations get contract tests, and the work is contracted through a US entity with full IP assignment.
Ecommerce specifics
- Storefronts are server-rendered with a CI-enforced performance budget, because Core Web Vitals affect both conversion and ranking.
- Migration plans preserve URLs, canonicals, and structured data so organic traffic survives the replatform.
- Marketplace and multi-party money flows are built on a proper ledger with reconciliation, not on platform payout reports.
- Every integration carries contract tests, so a carrier, tax, or ERP change surfaces in CI rather than in checkout.
How FISTA engineers
- Spec-Driven Development: every deliverable starts as a written specification with acceptance criteria, so scope is testable before it is built.
- AI-native delivery: engineers direct coding agents under review gates and evaluation harnesses, compressing build time without loosening verification.
- Official Anthropic partner, with production experience across Claude, OpenAI, Google, and open-weight models, chosen per workload rather than by default.
- One accountable delivery lead, weekly demos on your environment, and code in your repositories from week one.
What you get as a client
- 150+ projects delivered for 50+ companies across 12+ countries since 2017, with 99.9% verified uptime on systems we operate.
- A US entity (FISTA Solutions Inc., Wilmington, Delaware) for contracting, invoicing, and IP assignment, with an engineering center in Faisalabad, Pakistan for cost-efficient senior capacity.
- US business-hours overlap for standups and reviews; written decision logs so nothing depends on a meeting you missed.
- Flexible engagement: fixed-scope build, embedded forward deployed engineers, or a dedicated team that you can scale month to month.
Clear answers
What buyers in this industry ask first.
Straightforward guidance for evaluating scope, fit, and the next step.
01Should we go headless or stay on a monolithic platform?
Headless wins when performance, custom experience, or multi-channel delivery matter more than platform convenience; a monolith wins when the team is small and the storefront is standard. FISTA makes the recommendation against your traffic, catalog, team, and roadmap, and records the trade-offs.
02Will a replatform hurt our search rankings?
Not if migration is planned. FISTA maps URLs, preserves canonicals and structured data, plans redirects, maintains content parity, and monitors indexation after launch. Rankings are at risk when migration is treated as a deployment rather than as an SEO project.
03Can you build B2B features like contract pricing and approvals?
Yes. Account hierarchies, customer-specific price lists, quote workflows, purchase approvals, credit terms, and reordering are core B2B requirements that consumer platforms handle poorly, and they are specified explicitly rather than approximated.
04Can AI write our product descriptions?
It can draft them at catalog scale from supplier data and images, following your brand voice rules, with a human approving before publication. Accuracy on attributes is checked against source data, because wrong specifications generate returns.
05How do you handle inventory accuracy across warehouses and a 3PL?
With event-driven synchronization, an explicit reservation policy, and scheduled reconciliation against the system of record, plus exception queues where the numbers disagree — so mismatches are surfaced and resolved rather than silently oversold.
06How long does an ecommerce build take?
A focused storefront launch typically takes a few months; marketplaces and B2B platforms with deep ERP integration take longer. Data migration and third-party onboarding are the usual critical path, and discovery dates them.
