Custom Business AI Platform
Your business already has the knowledge a custom business AI platform needs. It lives in your emails, SharePoint, Teams chats, SOPs, spreadsheets, and CRM records.
Fusion Computing builds a governed AI platform over that data, so your team can ask better questions, automate repetitive work, and turn company knowledge into repeatable systems.

What a free discovery call covers
A custom business AI platform answers questions from your own documents and systems rather than the open web. Before building one, check whether Microsoft 365 Copilot already covers the task. Either way the first job is fixing who can see what, because Copilot surfaces only content a user has at least view permission for.
A free 30-minute discovery call covers the business task, current systems and users. We confirm whether a custom build is a sensible next step. If it is, a $750 scoped discovery sets the technical findings, the price and the delivery dates.
- ✓ An honest look at your data sources and systems
- ✓ The access and approval questions to cover in a paid scope
- ✓ The next step for a suitable business workflow
When Does a Custom AI Platform Make Sense?
Use Microsoft 365 Copilot when the licensed product and available agents cover the task. Consider a custom platform when the workflow needs source-specific integration, retrieval checks or approval steps that the selected product does not provide. Compare a real workflow before commissioning a build.
According to Statistics Canada’s 2026 analysis of AI use by businesses, 19.2% of Canadian businesses used AI to produce goods or deliver services in the previous 12 months. Among them, the most common uses were data analytics (36.6%), text analytics (34.5%) and virtual agents or chatbots (28.2%).
On small screens, swipe sideways or use the arrow keys to compare both routes.
| Buyer question | Microsoft 365 Copilot or a configured agent | Fusion Computing custom platform |
|---|---|---|
| Which sources can it use? | Microsoft 365 content and the sources supported by the selected agent or connector, subject to licensing and access. | The approved SharePoint, CRM, accounting or other sources named in the integration scope. |
| How is access controlled? | Microsoft applies the controls for the selected product. Permissions and connector configuration still need review. | We map each source’s access rules to retrieval and test allowed and denied requests. |
| Can users check an answer? | Grounded responses can provide references. Verify the behaviour against your actual sources and tasks. | The pilot tests source references, answer quality and what happens when evidence is missing. |
| Can it take action? | Agents and connectors can support actions within their configured permissions and capabilities. | The scope names the actions, approval points and exception handling needed by the workflow. |
| What are the ongoing costs? | Applicable Microsoft licences, agent usage and the time required to manage the configuration. | Build work, model and platform usage, connectors, support and maintenance are scoped separately. |
| When is this route a fit? | The available product meets the task and its controls can be configured for your users. | A valuable workflow needs integration or control behaviour beyond the selected product. |

Price range and written scope
Custom AI platform projects run CAD $5,000 to $50,000+, depending on scope. A $750 scoped discovery comes first. Your written proposal then names the sources, workflows and controls, and separates build cost from licences, usage and ongoing support before you commit.
A Managed AI Platform Built Around Your Company Knowledge
A custom business AI platform connects your company data and indexes it securely. It retrieves the right information at the right time. Your team gets a simple interface to ask questions, generate work, and trigger approved automations. Built around your business context, your users, your permissions, and your workflows.
Fusion Computing’s custom business AI platform is a governed AI system built on retrieval-augmented generation (RAG), a secure knowledge index, and a permission-aware retrieval layer. It answers from your own records, inside your own permissions. The same platform extends our existing Microsoft Copilot deployments and Power Automate consulting into something more durable: a productized custom AI integration platform. To put ChatGPT, Copilot or Claude straight onto one line-of-business system, see MCP server development.
What the Platform Includes
Bought the licences and nothing changed? Check product fit, training and governance before buying more tools. See AI enablement and training for how we take a team from licences to a measured change in how work gets done.
Six modular layers. The reusable foundation stays the same across clients. The custom work happens in the data ingestion layer where every business is different.
Data Ingestion & Connectors
We connect to where your knowledge already lives. That includes Microsoft 365, SharePoint, OneDrive, Teams, Outlook, CRM, accounting, PSA or ticketing, line-of-business apps, PDFs, spreadsheets, internal documents, websites, portals, and structured databases.
This is the custom layer. Fusion Computing defines the right ingestion plan before anything is indexed.
Secure Knowledge Index
Document parsing, metadata extraction, embeddings, vector search, structured document indexing, page-level indexing for long documents, source tracking, and permission-aware retrieval.
Retrieval is tested against agreed questions and source references.
Retrieval-Augmented Generation
RAG grounds AI answers in your company data. Users ask natural questions and receive answers based on approved internal sources, with references back to the documents, records, or systems used.
Ground answers in approved sources, show the evidence and test unsupported questions.

Business Memory Layer
Persistent context across interactions: company terminology, preferred response style, standard operating procedures, past decisions, customer-specific context, known exceptions, reusable workflows, and department-specific instructions.
Better continuity without uncontrolled access to everything.
Retrieval Tuning & Quality Review
Ongoing review of what your team asks, what the system retrieves, and where answers fall short, with chunking, ranking, and prompt tuning adjusted against real usage.
Frontend & Workflow Automation
Delivered through a web portal, Microsoft Teams, internal apps, workflow dashboards, department-specific assistants, Power Automate workflows, Azure Functions, and custom business process automations.
Ask the right question. Get a useful answer. Move work forward.
What Can a Custom Business AI Platform Do?
Six places a first workflow usually starts.
Company Knowledge Assistant
A secure place to ask questions about policies, procedures, client history, product information, internal documentation, and technical material.
Sales & Customer Response
Help sales and service teams draft replies, find past quotes, summarize customer history, compare product information, and prepare better responses faster.
Document Intelligence
Extract and compare information from PDFs, contracts, forms, invoices, reports, supplier documents, and spreadsheets.
Operations Automation
Turn repeatable manual work into AI-assisted workflows: report generation, intake processing, approval routing, ticket triage, and status updates.
Technical Support Assistant
Help staff search internal documentation, past tickets, vendor notes, troubleshooting steps, and known fixes.
Executive Q&A
Owners and managers ask business questions across multiple systems without manually pulling data from five places first.
Custom AI agents for Canadian businesses
Who builds custom AI agents for Canadian small and medium businesses? Fusion Computing designs, builds, and manages custom AI agents for Canadian SMBs from Toronto, Hamilton, and Metro Vancouver. Agent builds start with your permissions model and data boundaries, then automate the workflow end to end, whether that is a Copilot Studio agent inside Microsoft 365 or a fully custom build on your own systems.
An AI agent goes one step beyond a chat assistant: it completes multi-step work such as reading a request, checking your systems, drafting the response, and filing the result. We scope agent and workflow automation builds against the same security baseline as the platform above, so each agent is scoped to the permissions that govern your data.
According to joint guidance co-authored by the Canadian Centre for Cyber Security in 2026, AI agents that act across connected tools and data introduce significant security risks. The guidance, written with agencies in Australia, the United States, New Zealand and the United Kingdom, calls for a layered defence and strict access controls. Each agent build therefore starts from the permissions model before any workflow is automated.
Questions the first workflow can answer
“What did we quote this client last time?”
“Which supplier has the best price this week?”
“What does our policy say about this situation?”
“Which tickets point to a recurring operational issue?”
“What changed between these two contracts?”
“What should the next step be for this customer request?”
Built With Security Before Automation
The biggest AI risk for an SMB is an assistant connected to too much data too quickly. Fusion Computing starts with access, governance, and security controls before production rollout. The same controls already underpin our file labels, access checks, and data loss controls. We define least-privilege access, audit events and human approval steps in the written scope.
According to the OWASP Top 10 for LLM Applications 2025, prompt injection is the first risk, LLM01, and indirect prompt injection happens when a model accepts input from external sources such as websites or files. OWASP notes that retrieval-augmented generation does not fully mitigate it. A platform that reads company documents treats their text as untrusted. Actions require permission checks, and sensitive actions require human approval.
Role-based access
Permissions per user, group, and department.
Least privilege
The AI sees only what it needs to answer.
Microsoft 365 identity
Entra ID, sensitivity labels, conditional access.
DLP alignment
DLP integration and enforcement tests are defined in the written scope.
Audit logging
Queries, retrievals and actions logged as agreed in the scope.
Human approvals
Sensitive workflows pause for sign-off.
Source citations
Source references are checked against the pilot acceptance tests.
Data handling review
Document the selected services and their data-handling terms.
According to Microsoft’s 2026 documentation on data, privacy and security for models sold by Azure in Microsoft Foundry, prompts, completions and embeddings are not available to OpenAI and are not used to train generative AI foundation models without the customer’s permission. Those terms cover the model service. The custom application’s own access checks and data handling still need a separate review, which Fusion Computing scopes.

From Assessment to a Maintained Platform
Four phases. The first version focuses on high-value workflows. The fourth keeps the platform secure, current, and useful as your business changes.
Assess
We review your systems, data sources, workflows, permissions, and business priorities. You get a clear recommendation on where AI saves time, where automation makes sense, and what data should or should not be connected first.
Build
We configure the core AI platform, connect the first approved data sources, build the retrieval layer, and deliver the first working use cases. The first version focuses on the high-value workflows agreed in scope.
Optimize
We review usage, tune retrieval, add new data sources, improve prompts, and expand into additional workflows as your team gets comfortable.
Maintain
Monthly retrieval-quality reviews, source-index updates as your documents change, permission audits when staff join or leave, and quarterly roadmap sessions.

Common Questions Before Getting Started
Who builds custom AI agents for Canadian small and medium businesses?
Fusion Computing, a Canadian-owned, CISSP-led IT firm founded in 2012, designs, builds and manages custom AI agents and AI platforms for Canadian businesses with 10 to 150 employees. Each build starts from the firm’s permissions model and data boundaries, then automates one workflow end to end, either as a Copilot Studio agent inside Microsoft 365 or as a custom build on the firm’s own systems.
How is this different from Microsoft 365 Copilot?
Microsoft 365 Copilot and configured agents can already work with company content. A custom platform fits when the workflow needs integrations, retrieval checks or approval steps the licensed product does not provide. Fusion Computing reviews that gap before proposing a build, and recommends Copilot where it already covers the task.
How long does it take to get a working version?
The $750 scoped discovery defines the first version’s sources, workflows and controls. The written proposal then sets the delivery schedule before you commit. The first version delivers working use cases on the first approved sources. After that, retrieval is tuned and new sources are added as agreed in the scope.
What does a custom AI platform cost?
Fusion Computing’s custom AI platform projects run from CAD $5,000 to $50,000+, depending on scope. A $750 scoped discovery comes first. The written proposal then names the sources, workflows and controls, and separates the build cost from licences, model usage and ongoing support before you commit.
Will our data be used to train someone else’s AI model?
Microsoft’s terms for models sold by Azure in Microsoft Foundry state that prompts, completions and embeddings are not available to OpenAI and are not used to train generative AI foundation models without the customer’s permission. The application built on top still needs its own access checks and data-handling review. Fusion Computing documents the selected services and tests the source permissions in scope.
Can the platform trigger actions as well as answer questions?
Yes. The platform can call Power Automate workflows, Azure Functions or custom business process automations, such as routing an approval, opening a ticket or updating a record. Sensitive actions pause for a person to approve them, and actions are logged as agreed in the scope. Each action the platform may take is named in the written scope before it is built.
