74% of consumers expect more personalized experiences, according to Klaviyo’s 2025 Future of Consumer Marketing Report. But these days, consumer journeys are fragmented and non-linear, and they happen on many channels.
To connect with customers and drive revenue, the tools in your tech stack also need to connect with each other. Some B2C brands may need retail point of sale (POS) software that connects to their digital channels, while others need detailed analytics across the online customer experience, including marketplaces.
Whatever it looks like, 60% of B2C businesses have between 6–15 tools in their tech stacks, according to Klaviyo’s 2025 State of B2C Marketing Report. To scale your business and improve customer experiences, you need a CRM as a single source of truth for all these tools and data sources.
A CRM is more than a database. It’s a flexible system you can configure to meet the needs of your specific business model and growth goals.
CRM integrations, meanwhile, consolidate real-time customer data from all touchpoints into one place, so you can personalize communication with customers and gather insights that help you improve your marketing and customer service.
Here are 7 CRM integrations that connect your customer data and help you deliver better experiences, optimize spend, and engage your audience across physical and digital channels:
