Clockwise Software Reviews & Testimonials
Elliot Jacobs's Review Sourced from Google
We run a SaaS platform for PR reporting. It’s our first time working with an external development team after years of in-house. We made the shift to get more flexibility and to have dedicated capacity for building out a suite of new features on top of our product.The work is R&D by nature, so specs change, and priorities shift. Clockwise Software has always been flexible about that and scaled up when we needed more people involved. What else stood out is the team's experience. Our codebase spans multiple services with a fair amount of legacy code. They have people who've clearly worked across different codebases before, and it showed in how quickly they got productive.Our engagement is ongoing. We launched the new features, ran a beta, and opened it up to the full market. ARPC has increased since launch, a clear sign to us that the work landed well with customers.
Lukas Nchimbi's Review Sourced from Google
Hired them to build an AI feature on top of our internal system, basically an assistant so our team could ask questions and get info from our data instead of digging through it manually. Took about 8 weeks. Works exactly how we needed it to. Their team was upfront about the limitations early, which I actually respected.

5 Frequently Asked Questions About System Integrator Companies
Who needs system integrator company services?
Any business that uses multiple software systems and needs them to work together needs a system integrator. When systems are disconnected, data duplicates, processes slow down, and errors increase.
Typical use cases:
- Mid-size and enterprise companies that have multiple tools (ERP, CRM, HR, finance) that must share data
- Companies running legacy systems with outdated software that does not connect easily with modern tools
- Fast-growing businesses that are adding new tools quickly and losing control over data and workflows
- eCommerce and retail companies that need to sync orders, inventory, payments, and customer data in real time
- Manufacturing and logistics companies that require tight coordination between supply chain, inventory, and operations systems
- Finance and healthcare organizations that handle sensitive data and need secure, compliant integrations
- Companies undergoing digital transformation that move to cloud systems, automation, or new platforms
Clear signal you need an integrator:
- Data is entered manually into multiple systems
- Reports do not match across tools
- Teams rely on spreadsheets to “connect” systems
- Processes break when one system changes
- Scaling creates more errors instead of efficiency
At that point, integration is no longer optional.
How much do system integrator companies charge for their services?
System integrator services typically cost $15,000 to $1,500,000+, depending on how complex your systems are and how many platforms need to be connected.
Here is how pricing usually breaks down:
- Simple integrations (2 systems): $15,000 to $75,000
- Mid-level integrations (3–5 systems): $75,000 to $300,000
- Enterprise-wide integrations (5+ systems): $300,000 to $1,500,000+
Cost also follows a clear structure across the project:
- Planning and architecture: 10 to 20% of the total cost
- Development and setup: 50 to 70% of the total cost
- Testing and QA: 15 to 25% of total cost
- Training and rollout: 5 to 15% of total cost
There are ongoing costs that most companies ignore at the start. After launch, expect:
- Support and maintenance: 15 to 25% of the initial cost per year
- Cloud, tools, and licenses: Ongoing monthly or annual fees
- API and data usage costs: Depends on volume
Costs increase fast when systems are outdated, data is messy, or real-time processing is required. Legacy systems alone can add 20-50% to cost, and most companies should plan an extra 20-30% buffer for unexpected issues.
What is a typical timeline for system integration projects?
Most system integration service providers require from 3 to 18 months for their projects, depending on the number of systems, data complexity, and business size.
Here is how timelines usually break down:
- Small to mid-size projects: 3 to 9 months
- Large enterprise projects: 6 to 18 months
- Simple integrations (2 systems): 6 to 12 weeks
- Complex integrations (multiple systems): 9 to 18+ months
How system integration companies execute the project also affects speed:
- Phased rollout: 4 to 12 months, lower risk, more stable
- Big bang (all at once): 3 to 6 months, faster but higher risk
Several factors directly impact the timeline:
- Data cleanup and migration can take 15 to 20% of the total time
- Custom features add 3 to 6+ months
- Legacy systems slow everything down
- Testing and go-live add 1 to 2 months if done properly
Delays are common. Around 43% come from technical issues, and 40% from changing scope during the project.
How much downtime does system integration require?
Most system integrations require little to no downtime if planned correctly, but in practice, expect a few hours to a few days of disruption during final switchovers.
Downtime depends on how the company executes the project:
- Parallel integration (best case): Near-zero downtime
The new system runs alongside the old one, and then the switch happens quickly - Phased integration: A few hours at a time
Work is done in small parts during planned maintenance windows - Full cutover (big bang): Hours to several days
The entire system is replaced at once, with the highest risk of disruption
Several factors increase downtime risk:
- Legacy systems: Harder to connect, more failures
- Poor planning: No fallback or rollback options
- High system dependency: If one system fails, others stop
- No testing environment: Issues appear during live use
Strong teams reduce downtime by using backups, testing in advance, and scheduling work during low-activity periods. In well-managed projects, operations continue with minimal interruption.
What kind of support do system integrator companies provide after the project is finished?
System integration service providers do not stop at launch. They provide ongoing support to keep systems stable, secure, and working as expected. Without this, integrations break over time as systems update or data grows.
Post-project support usually includes:
- Fixing errors, broken connections, or data sync issues that appear after launch
- Tracking system health, fixing slow processes, and improving speed as data volume grows
- Adjusting integrations when connected platforms change or update
- Patching vulnerabilities and maintaining data protection standards
- Helping internal teams resolve issues and answering day-to-day questions
- Adding new features, connecting new systems, or expanding integrations as the business grows
- Providing guides and training so teams can use and manage the system properly
Most companies charge ongoing support as 15–25% of the initial project cost per year. Without this support, systems degrade, errors increase, and internal teams take on hidden maintenance work.
