Zapier plugs Rillet into 8,000 apps, betting AI and no-code can speed up the monthly close

Zapier is pushing deeper into the finance department, and it’s doing it by wiring Rillet’s AI-focused accounting platform into Zapier’s sprawling network of more than 8,000 apps.

The pitch is simple: connect Rillet’s general ledger to the tools companies already run, Salesforce, Stripe, support desks, internal databases, and automate the messy work that drags out month-end close. Zapier and Rillet say finance teams can build these workflows without engineers or pricey consultants, turning what can be a weeks-long scramble into something closer to a “continuous close.”

It’s a direct shot at a familiar pain point for CFOs and controllers: ERP rollouts that move slowly, systems that don’t talk to each other, and armies of spreadsheets filling the gaps.

A new bridge between the general ledger and the rest of the business

At the center of the partnership is a connector between Rillet’s “smart” general ledger and Zapier’s automation platform, which is best known in the U.S. for no-code workflows that move data between apps with point-and-click setup.

For finance teams, the practical promise is fewer CSV exports, less copy-and-paste, and less waiting on a technical team to build one-off integrations. Instead of treating the ERP as a closed system, the idea is to extend it across the rest of the stack, CRM, billing, customer support, and internal tools, so financial data reflects what’s happening in the business faster.

Zapier is also leaning hard into AI-driven automation, arguing that “agents” can help orchestrate multi-step processes like month-end close, general ledger syncing, approval routing, and reconciliations. The upside is speed and consistency. The downside is that bad automation can scale mistakes just as quickly as it scales efficiency.

What “continuous close” means, and why Rillet is built around it

Rillet is positioning itself as an AI-native accounting and ERP platform designed for continuous close, basically, shrinking the end-of-month bottleneck by keeping books closer to real time.

Zapier’s framing taps into a broader complaint about legacy ERP systems: many were designed for an earlier era and can take six months or longer to implement, often leaving teams stuck with manual reconciliations and slow-moving processes.

Rillet already offers native integrations with widely used tools like Salesforce, HubSpot, and Stripe. The Zapier partnership is meant to act as a multiplier: keep the most critical connections native, then use Zapier to link everything else without forcing the ERP to become the single system that does it all.

Two automations finance teams actually care about

The companies highlight workflows that sound mundane, but hit the heart of how finance work really gets done across departments.

One example: when a new customer is created in a CRM like Salesforce or HubSpot, that record can automatically populate inside Rillet with standardized fields, reducing data-entry errors and speeding up downstream accounting.

Another: when a Stripe payment fails or a refund is issued, the workflow can automatically create a follow-up task in a project management tool and notify the right owner. That kind of exception handling is where close cycles often get bogged down, small issues pile up until the end of the month, then explode into a fire drill.

No-code doesn’t mean no controls

Zapier’s core selling point, no-code automation, can be a genuine unlock for finance teams that don’t control engineering resources. You can set rules like: if an invoice exceeds a certain dollar threshold, trigger an approval chain and alert managers in the tools they already use.

But the same ease of building workflows can create a governance nightmare. If every team spins up its own automations, companies can end up with a tangled web of “Zaps” that are hard to audit, hard to version, and easy to break.

Finance leaders tend to be allergic to black boxes that write directly into the general ledger. The partnership’s success will hinge less on how quickly teams can automate, and more on whether they can enforce permissions, logging, documentation, exception handling, and change management so automation doesn’t become a faster way to be wrong.

Big numbers, bigger ambition

Both companies are using scale to sell the story. Zapier says it’s used by more than 3 million businesses and has processed more than 200 million AI-driven tasks, evidence, it argues, that it can serve as an orchestration layer for critical workflows, not just marketing and sales automations.

Rillet says it has more than 200 customers and raised a $70 million Series B led by Andreessen Horowitz (a16z) and ICONIQ Capital, two heavyweight Silicon Valley firms, bringing total funding to more than $100 million in under a year.

The broader bet is clear: instead of the old-school ERP model, monolithic suites, long implementations, and expensive customization, Zapier and Rillet are pitching a modular approach where finance runs on a modern ledger connected to the apps employees already live in. If it works, it could compress close timelines and give leaders a faster read on the business. If it doesn’t, companies may just trade spreadsheet chaos for automation chaos, only harder to spot.
