Sequence, a London-based platform that streamlines pricing, billing, and invoicing for B2B SaaS companies, replaced its existing unified API integration stack with Membrane, previously known as Integration App, to enhance its flexibility and customization capabilities. The switch was motivated by the need for real-time integrations and the limitations experienced with their previous provider, which included sync delays and inconsistencies across different applications. Membrane provided Sequence with a robust and consistent core across SaaS apps, real-time data syncing, and the ability to customize integrations per client or application. This transition allowed Sequence's engineering team to concentrate on core product development rather than constructing integrations from scratch, resulting in faster time-to-market for new features. With Membrane, Sequence successfully implemented over 20 different integration scenarios, including those with Xero, QuickBooks, Salesforce, and HubSpot, and plans to expand further into sales, document management, and e-signature tools.
