Software & AI engineering, end to end

We build the software your next stage of growth runs on.

OneScale Solutions designs, builds, integrates, and scales custom software, AI systems, and digital products — from idea to production — for startups, growing businesses, and enterprises anywhere in the world. Scoped honestly, shipped in weeks, and handed over in a state your team can actually maintain.

Why we exist

Most businesses that need custom software end up choosing between a slow enterprise vendor and a freelancer who disappears after launch. We built OneScale Solutions to be the option in between.

We scope before we build

A fixed proposal with a real timeline and price, before any code is written — not an open-ended hourly clock.

We build to be maintained

Documented, ordinary code your future in-house team can read — not a clever system only we can touch.

We stay after launch

Every project ships with a support window, and most clients keep us on retainer for what comes next.

What we build

11 services. One team you brief once.

Hire us for one project or lean on us as your ongoing engineering team — the scope changes, the way we work doesn't. If it's feasible and it's technology, we can probably build it — even if it's not listed here.

Software engineering

Custom software & web platforms

We design and build the software your business runs on — customer-facing products, internal tools, and full SaaS platforms — with an architecture that holds up as you grow, not one you'll have to rebuild in a year.

  • Product strategy and technical scoping before a line of code is written
  • Web applications built on modern, maintainable stacks
  • Internal tools and dashboards that replace spreadsheets and manual work
  • API design and third-party integrations
More on software engineering

Example brief

A subscription-box startup needed a customer portal to manage plans, pause deliveries, and view invoices without emailing support. We scoped, designed, and shipped it as a standalone web app connected to their existing payments provider.

AI & automation

AI systems & workflow automation

We build AI that does something, not just answers questions — customer-support agents, internal copilots, and automations that connect your tools together and complete tasks without a human doing them by hand.

  • Custom AI agents for support, sales, and internal operations
  • LLM integrations with your product or internal systems
  • Workflow automation across the tools you already use
  • Retrieval and knowledge-base setups so answers stay accurate
More on ai & automation

Example brief

A B2B services company was answering the same 20 questions over email every day. We built a support agent trained on their documentation that resolves routine questions and routes anything unclear straight to their team.

Mobile

Mobile applications

We build mobile apps that hold up past launch day — clean architecture, a design your users understand instantly, and a release process your team can maintain without us in the room.

  • Cross-platform apps for iOS and Android from a single codebase
  • Interface design centred on the two or three things users do most
  • Push notifications, offline support, and in-app payments where needed
  • App Store and Play Store submission handled end to end
More on mobile

Example brief

A neighbourhood laundry service needed customers to book pickups and track order status from their phone. We built and shipped the app in eight weeks, integrated with their existing order system.

Enterprise & data

Enterprise systems & data platforms

When spreadsheets, disconnected tools, and ageing systems start slowing a business down, we untangle it — connecting what you already have, migrating what needs to move, and building the data platform underneath it.

  • Legacy system audits and modernization roadmaps
  • Integrations between CRMs, ERPs, and internal tools
  • Data pipelines and reporting platforms
  • Migration planning with minimal downtime
More on enterprise & data

Example brief

A distribution business ran inventory in one system and orders in another, reconciled by hand each night. We built a sync layer between both and a dashboard that shows stock and orders in one place.

Integrations

System & platform integrations

Most businesses aren't short on software — they're short on software that talks to each other. We connect your CRM, ERP, POS, payment gateway, WhatsApp and telephony, and accounting tools into one working system, so a lead, order, or invoice only has to be entered once.

  • CRM, ERP, and POS integrations across the platforms you already run
  • Payment gateway and accounting system connections
  • WhatsApp Business API and telephony/IVR integrations
  • Custom middleware where no off-the-shelf connector exists
More on integrations

Example brief

A logistics company had leads landing in a form, quotes built in a spreadsheet, and invoices raised in separate accounting software — reconciled manually every week. We built a middleware layer that pushes each lead through to CRM, quote, and invoice automatically, with an alert on anything that fails.

Cloud & DevOps

Cloud infrastructure & DevOps

We design and manage the infrastructure underneath your product — cloud architecture, CI/CD pipelines, containerization, and monitoring — so scaling and shipping don't depend on one engineer knowing where everything lives.

  • Cloud architecture on AWS, GCP, or Azure, sized to actual load
  • CI/CD pipelines for automatic testing and deployment
  • Containerization and orchestration with Docker and Kubernetes
  • Monitoring, logging, and alerting wired in from day one
More on cloud & devops

Example brief

A SaaS product was deployed manually by one engineer, with no staging environment and no rollback plan. We built a CI/CD pipeline with automated tests, a staging environment, and one-click rollback — deployment time went from an afternoon to under ten minutes.

Product development

Product development: idea to scale

For founders who have the idea but not yet the team, we act as the technical side of the business — scoping the MVP, building it, watching how early users actually use it, and hardening it into something production-ready before you need to hire a full engineering team.

  • Idea validation and technical feasibility review
  • MVP scoped to what you need to test or raise on, not everything you imagine
  • Beta iteration based on real user feedback and usage data
  • Production hardening — security, performance, and scale — once the idea is proven
More on product development

Example brief

A founder had a validated idea and a deck, but no technical co-founder. We scoped a lean MVP, built it in six weeks, and stayed on through two rounds of user feedback before the product was ready for a seed-round demo.

Security & compliance

Cybersecurity & compliance

Security gets bolted on after a breach far too often. We build it in from the start — authentication and role-based access control, encryption, and compliance groundwork — and address the risks specific to AI systems, like prompt injection and over-permissioned agents.

  • Authentication, authorization, and role-based access control (RBAC)
  • Data encryption at rest and in transit
  • Compliance groundwork for GDPR, SOC 2, and industry-specific requirements
  • AI-specific security: prompt-injection defenses and agent permission boundaries
More on security & compliance

Example brief

A fintech startup needed SOC 2 groundwork before an enterprise client would sign. We ran a security audit, implemented RBAC and audit logging across the platform, and documented the controls their auditor needed to see.

Technical consulting

Technical consulting & fractional tech team

Sometimes what you need first isn't code — it's someone who's built this before telling you what will actually work. We provide architecture reviews, build-vs-buy analysis, and technology strategy, and for founders who want it ongoing, a fractional tech team on a monthly retainer.

  • Architecture and codebase reviews with a written report
  • Build-vs-buy analysis before you commit budget
  • AI and technology strategy for non-technical founders and leadership teams
  • Fractional CTO-style involvement — technical hiring, vendor calls, roadmap input
More on technical consulting

Example brief

A non-technical founder was about to sign a large contract with an agency. We reviewed the proposal, flagged the parts that were overbuilt, and helped negotiate a scope that cut the cost by a third without losing anything the product needed.

Managed services

Managed technology services

Most vendors disappear after launch. We don't — managed services means ongoing maintenance, monitoring, performance optimization, and new features on a predictable monthly retainer, so the system we built, or one you already had, keeps working as your business changes.

  • Ongoing bug fixes, updates, and dependency maintenance
  • Performance monitoring and optimization
  • New feature development within a predictable monthly retainer
  • Priority response for anything that breaks in production
More on managed services

Example brief

A client's e-commerce platform was stable but untouched for a year, running on outdated dependencies with no one watching uptime. We moved them onto a managed retainer, patched the security gaps, and now ship two to three small improvements every month.

Enterprise AI transformation

Enterprise AI transformation

For larger organizations, adopting AI well is an operating question as much as a technical one. We run a structured program — audit, identify, prioritize, build, deploy, scale — so AI rolls out where it actually moves the numbers, with the governance to match, instead of stalling as a one-off pilot no one owns.

  • AI readiness audit across teams, data, and existing systems
  • Use-case identification and prioritization by expected impact
  • Pilot builds for the highest-priority use cases first
  • Governance, monitoring, and change-management support for rollout
More on enterprise ai transformation

Example brief

A mid-size enterprise had three AI pilots running in different departments with no shared standards or ownership. We audited all three, consolidated them under one architecture and governance model, and helped scale the one with the clearest ROI company-wide.

How we work

Six steps, the same order, every project.

No surprises about what happens next — you know exactly where a project stands at every stage.

See the full process
  1. 01

    Discovery call

    A focused conversation about what's broken, what you're trying to achieve, and who the software is actually for. No sales pitch — we ask questions until the problem is clear.

  2. 02

    Scope & proposal

    You get a written scope of work, timeline, and fixed price before anything is signed. If something's unclear, we run a short paid discovery sprint rather than guess.

  3. 03

    Design

    Screens, flows, or architecture diagrams — whatever the project needs — reviewed with you before development starts, so changes happen on paper, not in code.

  4. 04

    Build

    Development happens in short cycles with a working preview you can check in on, not a single black-box delivery at the end.

  5. 05

    QA & launch

    Testing against real devices and real data, a staged rollout, and a launch day where we're on call in case anything needs attention.

  6. 06

    Support & growth

    Every project includes a fixed support window after launch. After that, most clients move to a monthly retainer for updates, new features, and maintenance.

Who we work with

Wherever your business is, there's a way to start.

Entrepreneurs

You have the idea and the drive, not yet a technical team.

  • Technical feasibility and scoping
  • MVP built around what you need to prove
  • Fractional tech-team support as you grow

Startups

You need an MVP that's good enough to raise on or sell with, built fast.

  • Fixed-scope MVP builds
  • Technical co-founder-style guidance
  • Built to hand off to an in-house team later

Growing businesses

Manual processes and spreadsheets are starting to cost you real time.

  • Internal tools that replace manual work
  • Integrations between the tools you already use
  • AI automation for repetitive tasks

SMBs

Small and medium teams ready to run on real software instead of workarounds.

  • Right-sized software builds, not enterprise overkill
  • AI agents that cover routine work without new hires
  • Ongoing support without a full in-house IT team

Mid-market companies

You've outgrown off-the-shelf tools but aren't enterprise-scale yet.

  • Custom platforms and internal tools
  • System integrations across departments
  • Data platforms and reporting

Enterprises

You have systems in place but need something specific built, connected, or modernized.

  • Legacy modernization and migrations
  • Enterprise AI transformation programs
