FAQ
Which systems can you connect?
Most business software including Salesforce, HubSpot, Shopify, WooCommerce, Xero, QuickBooks, SAP, and custom-built systems. If you've got older legacy software, I can connect that too. Message me with your specific tools, and I'll confirm compatibility.
How do you keep our data secure?
All connections use bank-level encryption and secure authentication. I follow GDPR-compliant practices and only request minimum permissions needed. Your data never passes through unsecured channels, and everything is tested thoroughly.
Can you work with our old legacy system?
Yes! I specialise in connecting older systems to modern platforms without replacing them. I build bridge APIs that extend the life of your existing infrastructure while letting you use new tools.
What happens if something breaks?
All integrations include error handling and logging, so issues get caught and reported immediately. You also get post-delivery support (7-30 days depending on package) to fix any problems. I build reliable connections that keep working.
Do we need to know technical stuff?
Not at all. I handle all the technical work. You'll get simple documentation explaining how everything works, and training on how to use your new automated workflows.
How long does integration actually take?
Simple connections take 5-7 days. More complex integrations with multiple systems need 12-18 days. After understanding your setup, I'll give you an accurate timeline.
What's included in ongoing support?
Post-delivery support covers bug fixes, answering questions, and minor adjustments. If you need ongoing maintenance after that period, I offer affordable monthly support packages.
Can you sync data in real-time?
Yes! Standard and Premium packages include real-time two-way sync. Change something in one system, and it updates everywhere else instantly.
