What we build
What does inventory management software development include?
Inventory work covers the stock model across locations and states, receiving and putaway workflows, pick and pack optimization, cycle counting, lot and serial traceability, and integration that keeps ERP and commerce channels consistent.
- 01
Multi-location stock model
Locations, bins, and states modeled explicitly so availability is meaningful rather than a single number.
Model - 02
Receiving and putaway
Purchase order receipt, discrepancy handling, and directed putaway that reflects real warehouse layout.
Inbound - 03
Picking and packing
Pick strategies, batching, and packing verification designed for throughput on handheld devices.
Outbound - 04
Counting and accuracy
Cycle counting workflows and variance investigation that keep accuracy high without full stock takes.
Accuracy - 05
Traceability
Lot and serial capture through receipt, movement, and shipment with fast recall queries.

Requirements
Which requirements shape inventory management software development?
Inventory systems are judged on accuracy and throughput. Requirements cover an honest stock model, handheld usability under time pressure, reliable scanning, and integration that never lets channels disagree about availability.
| Requirement | Why it matters | How FISTA builds to it |
|---|---|---|
| Stock accuracy | Wrong stock breaks every downstream promise. | Explicit state model, transactional movements, cycle counting, and reconciliation with exception queues. |
| Handheld throughput | Pickers are measured in seconds. | Scan-first workflows, minimal taps, offline tolerance, and testing on the actual handheld hardware. |
| Channel consistency | Commerce and ERP must see the same availability. | Event-driven synchronization with an explicit reservation policy and reconciliation against the system of record. |
| Traceability | Recalls and warranties need genealogy. | Lot and serial capture at every movement with query paths designed for fast recall response. |
| Peak throughput | Seasonal peaks break naive systems. | Load testing against peak order profiles, with queueing and back-pressure rather than timeouts. |
Where AI fits
Where does AI fit in inventory management software development?
AI fits inventory in exception work and forecasting support: investigating discrepancies, proposing corrections, summarizing demand signals for replenishment, and reading supplier documents — with adjustments always applied by an authorized human.
- 01
Discrepancy investigation
Variances investigated against movement history with proposed corrections for approval.
- 02
Replenishment signals
Demand and lead-time signals summarized for planners with the data attached.
- 03
Supplier document extraction
ASNs, packing lists, and certificates extracted into structured records tied to receipts.
- 04
Slotting suggestions
Bin and slotting proposals from pick frequency data, reviewed before implementation.
Cost and timeline
How much does inventory management software development cost, and how long does it take?
Cost is driven by warehouse complexity, hardware integration, and channel count; timeline by device procurement and go-live sequencing. FISTA does not quote blind: the scoping call returns a specification and a phased estimate.
Go-live sequencing matters more than feature completeness. Cutting over a warehouse is operationally risky, so FISTA plans parallel running, fallback procedures, and a phased location rollout.
Hardware reality shapes the build: handheld models, scanner behavior, and label printers all differ, so the device matrix is agreed and tested before the estimate is fixed.
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 custom software?
FISTA delivers custom software in four phases: a discovery sprint that turns goals into a specification with acceptance criteria, an architecture and data design with integration contracts, two-week builds with automated tests and weekly demos, and a verified release with infrastructure-as-code, runbooks, and monitoring.
- 1
Discover and specify
Workshops, process mapping, and system inventory produce a specification with acceptance criteria and a phased plan.
OutputSpecification, estimate, roadmap
- 2
Architect
Data model, service boundaries, API contracts, security, and infrastructure decisions recorded with trade-offs.
OutputArchitecture decision records
- 3
Build and demo
Two-week sprints with unit, integration, and contract tests; a demo on your environment every week.
OutputWorking increments in your repo
- 4
Verify and release
Performance and security testing against the spec, infrastructure-as-code, runbooks, dashboards, and handover or managed operations.
OutputVerified release with SLOs
Why FISTA
Why choose FISTA Solutions for inventory management software development?
FISTA builds inventory systems with an honest stock model, handheld workflows tested on real hardware, and go-live planned to protect operations. Work is contracted through a US entity with full IP assignment.
Inventory & WMS specifics
- Stock states and locations are modeled explicitly, so availability means something specific rather than a single ambiguous number.
- Handheld workflows are scan-first and tested on your actual devices under time pressure.
- Channel availability is synchronized event-driven with an explicit reservation policy and reconciliation.
- Go-live includes parallel running and fallback procedures, because a failed warehouse cutover stops shipping.
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 ask before a custom build.
Straightforward guidance for evaluating scope, fit, and the next step.
01Should we extend our ERP or build a separate WMS?
Extend when the ERP's warehouse capability fits your throughput and layout; build or integrate a dedicated system when picking strategy, handheld throughput, or traceability exceed what it offers. FISTA assesses against your actual operation.
02Will it work with our handheld scanners?
Yes, including hardware scanner integration and testing on your specific devices, because behavior and performance differ meaningfully across rugged Android hardware.
03How do you prevent overselling across channels?
Event-driven synchronization with an explicit reservation policy, reconciliation against the system of record, and exception queues where sources disagree.
04Can you support lot and serial traceability?
Yes, captured at receipt, movement, and shipment, with query paths designed specifically for fast recall response rather than as a reporting afterthought.
05How do you handle go-live?
With parallel running, documented fallback procedures, and phased rollout by location, because a failed warehouse cutover stops shipping immediately.
