Custom Enterprise Software Development

Custom software development
built around how your business runs

Off-the-shelf software was built for the average business. If your operations are more complex than average, and they usually are, we build the platform that fits. Custom software development services covering ERP replacements, operations platforms, B2B portals, legacy application modernization, and software project rescue.

Every build is AI-native by default, we design the data model and APIs so LLM features, RAG, and workflow automation drop in as a feature ticket later, not a rewrite. Built by engineers who ship AI to production, not just CRUD.

Why businesses call us about custom software

If two or three of these describe your operation, off-the-shelf is costing you more than it saves. Here is what we do about each.

The business runs on spreadsheets, email threads, and one person who knows how it all fits together.

One operations platform. Job management, scheduling, and reporting built around your workflow. It is the core of what we built for i-mve, now running dispatch for 510 UK companies.

The off-the-shelf system has been modified so heavily it is now the bottleneck.

We replace it with a cloud-native build. Deployed on AWS or Azure, containerised, with CI/CD from day one, and a data model built to evolve rather than fight you.

The same data gets re-entered across three systems every day.

We build the integration layer. ERP, CRM, and accounting kept in sync without manual re-entry. We have connected Xero, QuickBooks, Sage, Stripe, and Salesforce across live platforms.

A build stalled, went over budget, or was handed off by a team that has since gone.

Software project rescue. We audit the codebase and infrastructure, tell you what is salvageable, and take over delivery. You get the assessment before committing budget.

What We Build

Enterprise software, defined honestly

Not a Salesforce plugin. Not a WordPress site with extra steps. Software built from scratch for the operational complexity your business actually has.

Operations Management Platforms

Job management, scheduling, dispatch, and progress tracking built around your workflow, with the roles and rules your team needs. It's the core of what we built for i-mve, now running dispatch for 510 UK removals companies.

Business Process Automation

We automate the high-friction handoffs: approval workflows, document generation, status notifications, system-to-system data sync, and the repetitive data entry that causes errors. i-mve's quoting and invoicing engine now runs without anyone touching it.

B2B Client & Partner Portals

Self-service portals for clients, partners, or suppliers: submit requests, check status, access documents, and message your team. They cut support overhead and give clients the visibility they ask for at renewal. i-mve's client portal is built on this pattern.

Legacy System Replacement & Cloud Application Development

When an existing system has become the bottleneck: too slow to change, too costly to maintain, too limited for how the business has grown. We replace heavily-modified off-the-shelf software and dated custom apps with cloud-native platforms built to evolve. Deployed on AWS or Azure, containerised, with CI/CD from day one.

System Integration & Middleware

Enterprise operations run across several systems: ERP, CRM, accounting, carrier platforms. We build the integration layer that keeps data in sync without manual re-entry. We've connected Xero, QuickBooks, Sage, Stripe, and Salesforce across logistics, healthcare, and property.

Quality Assurance & Testing

"Works on my machine" isn't a QA process. Every sprint includes functional, integration, and regression testing before code reaches staging, plus structured UAT before go-live so launch day isn't your first real test.

Software Architecture & Consulting

Have a system that's slow to change or breaking under its own complexity? We review the architecture, name the real bottleneck, and give you a straight recommendation: sometimes a rebuild, sometimes targeted refactoring. Either way you'll know before committing budget to the wrong fix.

Software Project Rescue

A build that's stalled, over budget, or handed off by a team that's gone. We audit the codebase and infrastructure, tell you what's salvageable, and take over delivery: recovering what works, re-engineering what doesn't. You get a clear assessment first.

AI Technology Partner

Custom software that's AI-native from the data model up

There's a real difference between "we can add AI later" and "we architected for it." Most AI pilots die when a rigid legacy schema meets a language model. We build so that doesn't happen.

Architected for AI, not retrofitted

Structured data, clean APIs, and event streams mean an AI feature is a feature ticket, not a project. Retrofitting AI onto a tangled schema is where pilots stall for months. We design that out from phase one.

The AI & automation layer

LLM features inside your platform, RAG over your own data, intelligent document processing, agentic workflow automation, and AI copilots your team actually uses. Wired in with evals and guardrails, not a demo bolted to the side.

On your data, your workflows, your timeline

Off-the-shelf gives you AI features when the vendor ships them. Custom means AI wired into your data and your process, on your schedule, and you own it. It's how we built our own products, Tully AI and Mebag.

How We Work

Why enterprise software projects fail, and how we avoid it

Enterprise projects fail for predictable reasons: scope agreed before anyone understood the business, architecture decided before requirements were clear, data migration treated as an afterthought. We fix these deliberately. Here's the six-phase process every build runs through, refined across 600+ projects and eight years.

Start your project →
01

Discovery: We map what you actually do

Before architecture, technology decisions, or a line of code, we spend time understanding your operation. How does work enter the system? Who touches it? Where does it stall? What does the current process cost in time and errors? Most projects fail because the builders didn't understand the business well enough. We fix that upfront.

02

Architecture: Decisions that are expensive to change later

Data model, API structure, authentication, integration architecture, and deployment strategy are defined before development begins. Enterprise software runs your business for years, and the decisions made at the start stay load-bearing. We document them, explain the tradeoffs, and get your sign-off first. We also flag governance and compliance implications early (data residency, access control, audit trails) so they're designed in, not retrofitted after an audit.

03

UX Design: For the people who actually use it, not the demo

Enterprise software is used by people who didn't choose it: operations staff, field teams, finance teams with no interest in learning new tools. We design for adoption, not demos. Every screen is designed before implementation, and complex workflows are prototyped and validated with real users before code.

04

Development: Two-week sprints, real visibility

Development happens in two-week sprints. At the end of each one you see a working, deployable build, not a status update. You review it, sign off, and the next sprint begins. Scope changes are documented and priced before any extra work. Testing runs alongside every sprint, so 'complete' actually means complete and there are no surprises at the end.

05

Data Migration & Cutover: The part that sinks most replacements

Replacing a live system means moving years of real data (customers, jobs, invoices, history) without losing a record or a day of trading. We profile the source data early, write repeatable migration scripts, run full dry-runs against production copies, and reconcile counts and totals before cutover. Where it helps, we run old and new in parallel so the switch is reversible. It's how we moved removals firms onto i-mve and how COMPASS replaced paper-based clinical data collection.

06

Launch & Ongoing: We don't disappear after go-live

Production deployment with a CI/CD pipeline, plus documentation on architecture, deployment, and data model written to a standard your own team can maintain against. 30-day post-launch support is standard. Beyond that, long-term retainers are available: we've kept active development relationships with clients for years, and i-mve has been in continuous development with us since 2022.

Pricing

What enterprise software projects cost

We don't quote without a requirements conversation. Every build is fixed-price, never hourly. Here's what's included at each level of scope.

Focused Platform
Scoped to your build

A focused system solving a specific operational problem: a job management platform, client portal, or reporting dashboard with integrations. 12–20 weeks. One primary workflow, 3–5 user roles.

  • Core module development
  • 2–3 third-party integrations
  • Role-based access control
  • UX design included
  • 30-day post-launch support
Enterprise Platform + Phased
Priced after a scoping call

Large platforms replacing multiple existing systems, requiring phased delivery, data migration from legacy systems, and complex compliance requirements. Scoped and priced phase by phase.

  • Multi-phase roadmap
  • Legacy data migration
  • Client-directed data-handling controls
  • Ongoing retainer options
  • Team augmentation available

Everything above is a fixed-price build: we scope it, price it, and deliver it. If you'd rather add senior engineers directly into your own team instead of handing off a full build, that's a different model. See IT Staff Augmentation for how that works.

FAQ

Common questions

Straight answers on timelines, scope, integrations, ownership, and how we work with clients across the US, UK, and Australia.

What is a custom software development company, and what makes Teamseven different?

A custom software development company builds software from scratch around one organisation's workflows and rules, rather than selling a fixed off-the-shelf product. What makes us different is the order of work: we map how your business actually operates before we choose an architecture or write code, we deliver fixed-price rather than hourly, and full source code and IP ownership transfer to you on completion. We've delivered 600+ projects across enterprise operations platforms, B2B portals, and legacy system replacements.

How long does a custom enterprise software project take?

Most enterprise software projects run 16–36 weeks depending on scope. A focused system covering one primary operational workflow (job management, client portal, or reporting dashboard) is typically 12–20 weeks. A comprehensive platform replacing multiple existing systems with several integrations is 24–36 weeks. We provide a detailed timeline estimate broken down by phase as part of the scoping process, before any development starts.

How much does custom software development cost?

Every build is fixed-price and scoped to requirements; we don't quote without a requirements conversation. A focused platform solving one operational workflow runs 12–20 weeks; a full operations platform covering multiple workflows and integrations runs 20–36 weeks; enterprise platforms replacing several systems are scoped and priced phase by phase. You can get a rough range from our software development cost calculator, then a firm number after a scoping call.

Can you take over a project another team started or abandoned?

Yes. Software project rescue is a standard engagement for us. We audit the existing codebase and infrastructure, document what's salvageable and what isn't, and give you a straight recommendation: recover and continue, or re-engineer the parts holding the system back. You get that assessment before committing budget to a direction. We've done this with heavily-modified off-the-shelf systems and stalled custom builds alike.

Do you offer offshore and nearshore software development?

We're an offshore software development team based in Pakistan, working with clients across the US, UK, and Australia. Time zones with the UK and EU overlap through the morning, and we run afternoon overlap hours with Australia, close to nearshore working in practice for most clients. Communication runs over video call and Slack, with a fixed set of real-time overlap hours agreed at the start of each engagement.

Can you integrate with our existing ERP, CRM, or accounting software?

Yes. Integration with existing systems is a standard part of enterprise software projects. We've integrated with Xero, QuickBooks, Sage, Salesforce, HubSpot, Stripe, and various industry-specific platforms. Integration complexity depends on whether the system has a well-documented API, what data needs to flow in which direction, and how real-time the sync needs to be. We assess integration complexity during scoping and price it accurately, not as a vague line item to be resolved later.

Do you do discovery and scoping before development?

Yes, and we consider it non-negotiable for enterprise projects. Discovery is the phase where we map your workflows, document requirements, define the scope, and produce the functional specification that development is built against. For smaller, more focused projects, discovery is typically one to two weeks and included in the project cost. For larger projects, we sometimes run a paid discovery sprint that produces a full functional specification and architecture document before the development contract is signed.

Can you work alongside our internal development team?

Yes. We've worked as both the sole development resource and as an augmentation to an internal team. When working alongside internal developers, we align on architecture, coding standards, and process before starting. The working model (whether we own specific modules, work in shared repositories, or run a parallel track) is agreed upfront based on what's most effective for the project.

What happens after the project launches?

Every project includes a 30-day post-launch support window covering bug fixes and production issues at no additional charge. Beyond that, we offer ongoing retainer engagements for continued development: adding features, handling maintenance, and responding to operational needs as the business evolves. We've maintained active development relationships with clients for years. The i-mve platform has been in continuous development since 2022.

Who owns the source code once the project is finished?

You do, completely. Source code, architecture, and all associated IP transfer to you as part of every engagement. There's no license lock-in, and nothing about how we build ties the software back to us after handoff.

Do you work with UK and Australian enterprise clients?

Yes. We work with clients across the US, UK, and Australia. Most client communication happens over video call and Slack. Time zones between Pakistan and the UK overlap well in the morning, and we run overlap hours with Australia in the afternoon. For UK clients, we're familiar with GDPR compliance requirements. For Australian clients, we've worked under the Australian Privacy Act and are experienced with GST invoicing for Australian entities.

How do you handle security and compliance on enterprise builds?

Security is designed in, not bolted on. We follow OWASP Top 10 practices as a baseline: parameterised queries, encoded output, encryption in transit and at rest, role-based access control, and audit logging on sensitive actions. For regulated work we go further. COMPASS was built to the data-handling requirements of clinical research at an accredited US university, and Rezi24, a German healthcare SaaS we built, runs GDPR-compliant on German data centres. During architecture we map your specific obligations (GDPR, HIPAA-aligned handling, the Australian Privacy Act, sector rules) and design data residency, access control, and retention against them.

Why choose a specialist agency over hiring in-house or a large offshore firm?

In-house hiring makes sense once you have a permanent product team and a steady roadmap. For a first build, or a replacement of an existing system, you need senior people who've shipped this kind of platform before, and you need them now, not after a six-month hiring cycle. We've delivered 600+ projects over eight years, we're a Fiverr Vetted Pro agency with 353 five-star reviews, and the same core team stays on your project from discovery to launch. Unlike a large offshore shop, you're not handed to a rotating bench; you work directly with the people writing the code, in your overlap hours.
