POS integration and extensions
Custom flows, loyalty and offer integration, and endless-aisle capability around your POS without expanding PCI scope.
Register - 03
Inventory and replenishment
Store and DC inventory accuracy, safety stock and replenishment logic, cycle counting, and shrink visibility.
Inventory - 04
Omnichannel fulfillment
Buy-online-pickup-in-store, ship-from-store, and transfer orchestration with sourcing rules that respect store labor reality.
Fulfillment - 05
Clienteling and loyalty
Associate-facing customer history, appointment and outreach tooling, and loyalty mechanics integrated across channels.
Customer - 06
Retail AI agents
Demand-signal summaries, task prioritization, customer service answering, and exception investigation for inventory and pricing.

Requirements
Which requirements shape retail software development?
Retail software must work on the floor, not just in a demo: store devices are shared and intermittently connected, associate turnover means interfaces must be learnable in minutes, inventory accuracy governs every downstream promise, and register systems must stay inside a tight PCI perimeter.
| Requirement | What it means here | How FISTA builds to it |
|---|---|---|
| Store reality | Shared devices, gloves, noise, and unreliable Wi-Fi. | Offline-capable apps, large touch targets, fast session switching, and workflows that survive interruption mid-task. |
| Learnability | High turnover means training time is scarce. | Task-oriented interfaces, progressive disclosure, in-app guidance, and usability testing with actual store associates. |
| Inventory accuracy | Every omnichannel promise depends on knowing what is on the shelf. | Event-driven updates, cycle-count workflows, exception queues, and reconciliation with the merchandising system of record. |
| PCI scope | Payment acceptance at the register defines your audit boundary. | Payment handling kept in certified terminals and providers, with applications exchanging tokens rather than card data. |
| Labor rules | Scheduling and task assignment intersect with labor regulations. | Configurable rules per jurisdiction, auditable schedule changes, and integration with workforce management rather than a parallel system. |
Where AI fits
Where do AI agents fit in retail?
AI agents fit retail where data volume exceeds analyst time and stores need answers now: demand and markdown signal summaries, task prioritization by store conditions, customer service answering, inventory exception investigation, and associate knowledge lookup. Pricing and markdown decisions remain with merchants.
- 01
Demand signal agent
Summarizes sales, weather, and promotion signals per store and category with the data attached for a planner to act on.
- 02
Store task agent
Prioritizes the day's tasks per store using inventory, traffic, and compliance signals, adapting when the day goes sideways.
- 03
Customer service agent
Answers order, availability, and returns questions from read-only systems, handing anything policy-related to staff.
- 04
Inventory exception agent
Investigates negative on-hands, phantom stock, and transfer discrepancies, proposing corrections for approval.
- 05
Associate knowledge agent
Answers product and procedure questions from approved content with citations, replacing binder hunts on the floor.
Cost and timeline
How much does retail software development cost, and how long does it take?
Cost is driven by store count, device diversity, integration with merchandising and POS systems, and rollout logistics; timeline by pilot cycles and store training. FISTA does not quote blind: the scoping call returns a specification, a rollout plan, and an estimate.
Rollout is a real cost line in retail, not an afterthought. Software that works in ten pilot stores still needs device management, training material, support escalation, and phased deployment across hundreds of locations. FISTA plans the rollout with you and prices it, because the chain-wide launch is where most retail programs actually stumble.
Integration depth sets the rest. Reading inventory is cheap; writing adjustments, orchestrating transfers, and reconciling against merchandising is where the engineering lives. FISTA sequences those so stores get value from the read-only capabilities while the write paths are proven carefully.
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 retail software development?
FISTA designs retail software for the floor: offline-capable, learnable in minutes, and tested with real associates. Integrations carry contract tests, PCI scope stays with certified terminals, and the work is contracted through a US entity with full IP assignment.
Retail specifics
- Store apps are offline-capable and interruption-tolerant, tested on the devices your associates actually use.
- Usability is validated with store associates, not just with head-office stakeholders.
- Payment stays inside certified terminals and providers, keeping applications out of PCI audit scope.
- Rollout — device management, training, support paths — is planned and priced with the build, not after it.
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.
01Can you build software that works when the store loses connectivity?
Yes. Store applications are built offline-first: tasks, counts, and evidence are captured locally and synchronized with conflict resolution when the network returns, and workflows are designed to survive interruption mid-task.
02Will a custom retail app expand our PCI scope?
Not if it is designed correctly. Payment acceptance stays inside certified terminals and providers, with your applications handling tokens and references rather than card data. The scope boundary is documented in the architecture for your assessor.
03Can you integrate with our existing POS and merchandising systems?
Yes, through their supported interfaces, with an integration layer so store applications are not coupled to vendor-specific formats and upgrade cycles. Every boundary carries contract tests.
04How do you handle rollout across hundreds of stores?
With a phased plan: pilot stores, measured outcomes, device management and training material, support escalation paths, then waves. The plan and its cost are agreed during discovery rather than improvised after the build.
05Can AI set prices or markdowns?
FISTA builds agents that surface demand signals, margin risks, and recommendations with the supporting data, but pricing and markdown decisions stay with merchants. Automated repricing without human authority creates margin and legal exposure that most retailers do not want.
06Do you work with grocery and convenience operators?
Yes. Those formats add perishability, shrink, and high transaction velocity to the requirements, which changes inventory logic and store task design but not the delivery approach.
