HubSpot is a powerful CRM and email marketing platform - but it's not a billing system.

Anyone who has tried managing SaaS renewals in HubSpot already knows the limitations. While HubSpot allows for the creation of simple quotes and can set up recurring billing (e.g., 10 users per month), that’s where its billing capabilities largely stop.

It lacks essential features needed by B2B SaaS companies: quoting for amendments and renewals, tiered or volume-based pricing, price overrides, ramp deals, scheduled changes, and more.

At OneLogin, for example, the sales team generated quotes in one system while the finance team manually recreated everything in two others. This resulted in hours of wasted effort, data entry errors, and a tangle of spreadsheets just to track what was sold versus what was billed. Revenue recognition often became a spreadsheet-driven nightmare. - Thomas Pedersen, CEO

HubSpot’s quoting is optimized for one-time or simple recurring sales, but it doesn't support renewal management, upsell workflows, or customer-specific pricing. Trying to configure a ramp deal or a future-dated price adjustment reveals the platform's limitations almost immediately.

Moreover, HubSpot doesn't address the accounting side of things: accrual accounting, revenue recognition, or compliance with standards like ASC 606 and IFRS 15. Teams are left to manage this critical functionality manually in disconnected systems.

That’s why Bunny was built - a system-of-record for all B2B SaaS revenue. Bunny is purpose-built to support both product-led and sales-led growth. It delivers advanced capabilities for subscription management, billing, and analytics, enabling SaaS businesses to track key metrics like cohort retention, CAGR, NRR, GRR, and ARR.

SaaS companies are busy enough building their own product. They shouldn't have to also build billing.

SaaS companies need specialized tools that were designed from day one to handle the complexities of B2B subscription revenue.
