Connect Everything You Use
CRM, accounting, payments, calendars, email, telephony, WhatsApp and custom APIs. One connected business ecosystem.
The average business uses 15-30 different software tools. And most of them don't talk to each other. Data gets entered twice. Reports require manual exports. Context is lost between systems. Switch2One connects your entire software stack so it functions as one ecosystem. We integrate CRM with accounting. We sync calendars with booking systems. We connect telephony with customer records. We bridge WhatsApp, email and helpdesk. We handle data migrations when you switch systems. And when no off-the-shelf integration exists, we build custom API connections. The result: data flows automatically, nothing lives in isolation, and your team stops being the integration layer between disconnected tools.
Business Problems We Solve
Double Data Entry
Customer information gets typed into CRM, then accounting, then email. Wasting time and introducing errors.
Manual Exports
Reports require exporting from one tool, manipulating in a spreadsheet and importing to another. Every single time.
Lost Context
When systems don't connect, customer conversations in email aren't visible in your CRM. Context is lost.
Siloed Tools
Each department uses its own tool, creating data silos that prevent a unified view of the business.
Capabilities

Connect your CRM with website forms, email marketing, accounting, calendars and telephony. So customer data flows automatically.

Sync invoices, payments, expenses and financial data between your accounting software and operational systems.
Payment Integrations
Stripe, Mollie, PayPal and other payment providers connected to your webshop, CRM and accounting. End-to-end transaction flow.
Calendar & Booking
Google Calendar, Outlook, Calendly and custom booking systems synced with your CRM and customer communication.
Communication Tools
Slack, Microsoft Teams, WhatsApp Business, email and telephony. Unified and connected to your business data.
Custom APIs & Webhooks

Business Benefits
No More Double Entry
When systems are connected, data enters once and flows everywhere. No more copying customer info from email to CRM to accounting.
Real-Time Data Everywhere
A customer updates their address. It syncs to CRM, accounting and shipping instantly. Every system has the current truth.
Reduced Human Error
Manual data transfer introduces errors. Automated integrations eliminate typos, missed fields and forgotten updates.
Scalable Architecture
As you add tools, they connect to the existing integration layer. New systems plug in rather than creating new silos.
Use Cases
Businesses wanting to eliminate double data entry across CRM, accounting and marketing tools
Companies connecting telephony and WhatsApp with their CRM for unified customer communication
Organizations migrating between systems with complex data mapping requirements
Teams wanting to automate data sync between their webshop, inventory and accounting

Frequently Asked Questions
Can you integrate systems that don't have public APIs?
Often yes. We use techniques like webhooks, database connections, file-based sync and screen scraping where appropriate. If a system truly has no integration path, we'll tell you honestly and recommend alternatives. We don't promise what we can't deliver.
Should we use Zapier, Make or custom integrations?
It depends on volume and complexity. Zapier and Make are great for simple, low-volume automation. For high-volume data sync, complex business logic or sensitive data, custom integrations are more reliable, faster and cheaper at scale. We assess your needs and recommend the right approach.
Can you migrate our data when switching systems?
Yes. Data migrations are a core part of integration work. Whether you're switching CRM, accounting or marketing platforms. We handle data cleaning, mapping, validation and migration with minimal downtime and full backup safety nets.
