🔴 Worst Experience Ever with Celestial Infosoft 🔴
Dealing with this company was a total nightmare. They claimed to offer professional development services, but all they really do is resell cheap code from Envato. No original work, no skilled developers — just false promises.
I paid them in advance and got nothing but delays, excuses, and poor communication. They clearly lack knowledge and don’t have a real team. I wasted my time, energy, and money.
This was the WORST experience I’ve had with any tech company. Highly unprofessional. Totally unreliable. ⚠️
Don’t fall into the trap. Avoid Celestial Infosoft.

Anubhav Chaudhary's Review Sourced from Google
Partnering with Scallar IT Solution for our clinic's complete digital transformation has been one of the best decisions we've made for our practice. Before working with them, our patient scheduling, follow-ups, and online presence were scattered across manual registers and disconnected tools. Scallar built us a professional, mobile-optimized clinic website with online appointment booking, integrated a CRM system to manage patient records and follow-ups, and set up WhatsApp automation for appointment reminders, prescription follow-ups, and patient queries — available 24/7. They also handled our Google Business Profile optimization and local SEO, which has significantly improved our visibility for patients searching for clinics near them. On top of that, their digital marketing support through Google Ads and social media has brought in a steady stream of new patient inquiries every month. The entire process — from website development to CRM integration, automation, and marketing — was handled professionally with clear communication at every step. Our administrative workload has reduced drastically, patient communication has become seamless, and our clinic's online visibility has grown remarkably. Highly recommend Scallar IT Solution to any clinic or healthcare practice looking for end-to-end digital transformation, healthcare automation, and patient engagement solutions.

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.
