System Integration Services for Your Business Software

When Your People Become the Integration

Most companies run on more systems than they planned: an ERP, a CRM, a few spreadsheets, a supplier or customer portal, and an older application nobody wants to touch. When those systems don't talk to each other, your employees become the integration layer.

The same data typed twice

Orders are entered into the CRM, then re-entered into the ERP, creating delays and opportunities for error.

Spreadsheets in the middle

Employees export, edit, and re-import files every week just to move information between systems.

Numbers that don't match

Sales, finance, and operations each report different numbers because data is stored in different systems.

Partners waiting on email

Suppliers and customers need information that's already in your systems, but someone still has to manually check and respond.

An old system that still works

A critical application runs part of the business, but sharing data with newer systems is difficult or impossible.

Too many logins

Employees juggle separate usernames and passwords across multiple systems instead of signing in once.

Benefits of System Integration

The biggest benefit of system integration isn't technical. It's giving people accurate information without forcing them to re-enter data, exchange spreadsheets, or chase updates across multiple systems.

Enter data once

Orders, customers, and suppliers are entered one time and automatically shared with the systems that need them.

Fewer manual errors

Eliminate re-keying between applications and validate information as it moves between systems.

Reports you can trust

Sales, finance, and operations work from consistent data instead of separate spreadsheets and disconnected reports.

Faster customer and supplier processes

Status, orders and approvals move as they happen, not when someone sends an email.

No spreadsheet handoffs

Replace error-prone exports and imports with automated, monitored data exchanges.

More for AI and automation to work with

More complete data for AI and automation. When information flows between systems, AI tools and automated workflows can work from a broader and more consistent set of business data.

The result: Less duplicate work, fewer errors, more reliable reporting, and business processes that move at the speed of your operations instead of your inbox. Looking to add AI assistants, AI reporting, or workflow automation? AI can be added to any of your systems, connected or not. See AI integration services →

How we connect each ERP and CRM →

ERP and CRM System Integration Services

Your ERP should stay the system of record. We connect it to your CRM, portals, databases and reporting so orders, customers, items and suppliers are entered once and stay the same everywhere.

Item	Typical integrations
Custom ERP or line-of-business application	Customer portals, supplier portals, reporting databases, mobile applications, warehouse systems and external partners.
SAP S/4HANA	CRM systems, reporting platforms, supplier portals, custom applications and AI solutions.
Oracle	Custom applications, reporting databases, business intelligence tools and partner systems.
Microsoft Dynamics 365 Sales	ERP systems, customer portals, custom applications and reporting platforms.
Salesforce	ERP systems, mobile apps, customer portals, reporting solutions and business workflows.

Depending on the platform, we connect systems through APIs, databases, file transfers, event processing, extension frameworks, custom code, and cloud services such as Azure Functions.

ERP systems are part of SharpQuest's foundation

We've built custom ERP and manufacturing systems and integrated existing ERP, purchasing, inventory, supplier, and reporting platforms for organizations such as TKS Industrial, American MSC, and SanDisk. Many of our integration projects support manufacturing, automotive, and industrial companies where accurate data flow between business systems is critical. In addition to custom ERP platforms, we have experience integrating with enterprise ERP solutions such as SAP S/4HANA and Oracle through their available APIs, databases, and integration frameworks.

How We Connect Systems, With or Without APIs

Not every system has an API, and that's fine. We pick the method each system supports and the speed the process needs.

APIs

When applications provide APIs or when new APIs need to be created for other systems, partners, or mobile applications.

API development →

Direct database access

For custom, legacy, or home-grown systems where database integration is the most practical option.

File exchange and EDI

When systems communicate through CSV, Excel, flat files, EDI documents, ACH files, or benefit enrollment files.

Platform extensions

When business platforms such as Salesforce, Dynamics 365, or custom ERP systems provide built-in extension capabilities.

Single sign-on

When users need one login across multiple business systems.

Background services

For scheduled imports, exports, monitoring, synchronization, and long-running integration processes.

Real-time or scheduled

Customer orders, status updates, and operational workflows often need real-time integration. Large imports, reporting updates, and reconciliation processes can usually run on a schedule. We help determine the right approach based on the business process.

Integrate, replace or modernize?

If a system still supports the business, integration is often faster, less disruptive, and less expensive than replacement. If the application is unsupported, creates security risks, or becomes a bottleneck for future improvements, we'll tell you and discuss application modernization options instead.

Our System Integration Process

Before we write code, you'll know which data moves where, which system is the source of truth, and what happens when something goes wrong.

Free integration review

You tell us which systems you run and where data is re-typed. We reply within two business days.
Discovery and mapping

We identify the source of truth for every major business entity, including customers, products, orders, suppliers, inventory, and pricing data. Then we map how changes move between systems and what happens when records conflict. For larger projects we recommend a paid discovery phase, with no obligation to continue. You get a requirements document or in-scope/out-of-scope list, an estimate and a high-level plan.
Design and documentation

We document how data moves between systems, how failures are handled, and how integrations are monitored. Technical specifications are completed before development begins.
Build in sprints

Development takes place in two-week (or mutually agreed) sprints with regular demonstrations. Work is completed in development and QA environments using test copies or sandbox versions of your systems.
Test with real data

We verify that data moves correctly between systems, reconcile records against source systems, and complete user acceptance testing with your team before go-live.
Launch and support

We monitor the integration after go-live, address issues, and offer ongoing support and enhancement options, with response targets from same-day to two business days.

After launch: see our support plans.

Support Plans

Ongoing support plans are available with response targets ranging from same-day to two business days.

	Essential	Professional	Premium
Hours per month	10	20	40
Response time	Within 2 business days	Next business day, priority	Same day in business hours, highest priority

Integrations Built to Keep Running

An integration is only useful if people can trust it. These are the standards every integration we build meets.

Logged and monitored

API calls, file transfers, and background processes are monitored and logged, with alerts when failures occur so issues can be addressed before they affect users.

Designed for recovery

Failed transactions are logged, retried where appropriate, and made visible so issues can be corrected without losing data.

Secure

Integrations follow least-privilege access principles, role-based security, encryption in transit and at rest, and secure development practices based on the OWASP Top 10. Single sign-on through Microsoft Entra ID is supported where appropriate. We sign HIPAA Business Associate Agreements (BAAs) for healthcare projects.

Checked data

Business rules and validation checks prevent invalid records from spreading across connected systems.

Separate environments

Development, QA, staging, and production environments help ensure changes are tested before deployment to live systems.

Backed up

Critical data is backed up regularly, and restoration procedures are tested before major deployments and migrations.

Documented and handed over

Data mappings, integration workflows, API documentation, deployment procedures, and operational notes are provided so your team can support the solution after launch.

Why SharpQuest for System Integration

Based in Troy, Michigan since 2009. We're a business software company, not a hardware or automation integrator: we connect the applications and data your business runs on.

Custom and packaged systems

Many integration firms only connect commercial software. We also work inside custom applications, home-grown ERP systems, legacy databases, and business platforms that have evolved over years of internal development.

Our own team, no subcontractors

Everyone working on your project is a SharpQuest employee, providing continuity, accountability, and direct communication throughout the engagement.

Confidential from day one

We sign your NDA, or use our own, before you share system details.

Professionally insured

SharpQuest carries professional liability (E&O) insurance, providing additional protection for clients and projects.

Long-term partner

Some clients have worked with SharpQuest for more than eight years, adding new modules, integrations, reports, and business capabilities as their organizations grow.

More than integration

If the software you need doesn't exist, we can build it. Many projects start with an integration and later expand into custom portals, ERP enhancements, reporting systems, workflow automation, or AI solutions.

Experience with legacy systems

We've integrated custom ERP systems, Microsoft Access databases, flat files, EDI processes, Salesforce, SQL Server, and modern cloud platforms. We are comfortable working with both old and new technology. We can also modernize your legacy applications.

System Integration FAQs

What is system integration?

Connecting separate software applications and databases, such as an ERP, a CRM, a supplier portal and an older in-house system, so they share data automatically instead of people re-typing it. The result works like one system, even though each application keeps its own job.

Is system integration the same as application integration?

Mostly. Application integration services connect software applications to each other; system integration also covers the databases, files, devices and sign-in around them. On a typical project we do both: connect the applications, and the data and logins they depend on.

Do all our systems need APIs?

No. We use APIs where a system has them, and direct database access, file exchange or the platform's own extension points where it doesn't. For a custom application we can add an API to the code.

Which ERP and CRM systems do you integrate?

We integrate custom ERP systems, line-of-business applications, Microsoft Dynamics 365 Sales, Salesforce, Oracle-based systems, SAP S/4HANA, SQL Server databases, Microsoft 365, payment gateways, trading partner EDI systems, and many other business platforms. We can connect systems through APIs, databases, file exchanges, single sign-on, or custom development depending on the capabilities available.

Do we have to replace our old system?

Not if it still does its job. Connecting it is usually faster and lower-risk. If it runs on unsupported technology or blocks the changes you need, we'll suggest modernizing that part.

How much does system integration cost?

It depends on how many systems are involved, whether they have APIs, the quality of the data and whether data must move in real time. Integration projects range from simple point-to-point connections between two systems to larger projects involving multiple business applications, databases, and external partners.

How long does an integration project take?

It depends on scope. Simple integrations can often be completed in days or weeks, while projects involving multiple systems, data migration, business rules, or third-party vendors typically take longer. After reviewing the scope, we provide an estimate and implementation plan.

Real-time or scheduled: which do we need?

Real-time for things people wait on, such as orders, approvals and status updates. Scheduled for reports, large imports and nightly reconciliation. Many projects use both; we agree it with you during discovery.

How do you keep integrated data secure?

Each integration gets only the access it needs. We use role-based access, encryption in transit and at rest, single sign-on with Microsoft Entra ID and logging of every call, and follow secure development practices based on the OWASP Top 10. We sign HIPAA BAAs for healthcare projects.

What happens when a connected system changes or an integration fails?

Failures are logged and monitored so issues can be identified quickly. We offer ongoing support plans to maintain integrations, address vendor API changes, and assist with upgrades or enhancements.

Can you work with our IT team and our vendors?

Yes. We follow your standards and release process, work with your ERP or CRM vendor's documentation and sandbox, and hand over data maps and API documentation as set out in your contract.

Do you build integrations only, or can you build the software too?

Both. Many clients engage SharpQuest to connect existing systems, but we also build custom applications, portals, APIs, reporting solutions, workflow automation, ERP enhancements, and AI-powered tools when an off-the-shelf solution doesn't exist.

Can you integrate cloud and on-premises systems?

Yes. We regularly connect cloud platforms, on-premises applications, databases, Microsoft 365 services, third-party providers, and legacy business systems. The integration approach depends on the capabilities each system provides.

Are you a US-based company?

Yes. SharpQuest is a US software development company headquartered in Troy, Michigan. We deliver system integration and custom software projects for organizations across the United States and work remotely with clients nationwide. When required, we can travel to client locations for requirements, testing or launch.

Can we add AI to our systems?

Yes. AI can be added to a single application or across multiple connected systems. Common uses include document processing, AI assistants, reporting, knowledge search, customer support, workflow automation, and data entry assistance. System integration can help AI access a broader set of business data, but connected systems are not required for AI adoption. See AI integration for ERP and AI integration services.

Who owns the code and intellectual property?

Ownership of the source code and intellectual property is set out in your contract with us. We agree on it before work starts, so you know exactly what you will own. At handover you get the source code, documentation and environment access your contract covers.

Will you sign our NDA?

Yes, we sign your NDA, or use our mutual NDA, before you share project details.
