From zero to $7 million ARR: How BIK.ai adopted AI billing from day zero
India
AI SaaS
600+ global brands
AI billing is super complicated. Without billing software, we'd never have had the telemetry to measure usage accurately. That's why we adopted Zoho Billing from day zero.
Co-founder & CEO, BIK.ai
BIK.ai builds full-funnel AI agents for ecommerce brands to automate marketing, customer acquisition, and post-purchase support across the customer journey. Founded in late 2022 by Sonakshi Nathani and Ashutosh Singla, the platform serves more than 600 brands across India and the United States, including LEGO, Duroflex, Wonderchef, and more.
The company's roots trace back to 2020, when its founders built an app that helped millions of small businesses launch online stores. That experience revealed where AI could create the biggest impact for ecommerce brands.
BIK.ai launched with a clear vision: Automate the complete technology stack for ecommerce brands, from the first shopper interaction to the final support resolution. In about three years, that vision translated into $7 million in annual recurring revenue (ARR), with more than 600 brands across India and the United States running on the platform
The challenge
BIK.ai's AI pricing model presented requirements that a standard subscription platform was not designed to handle. Unlike traditional SaaS, AI billing isn't based on fixed subscriptions. Pricing depends on real-time AI-credit consumption across every workflow and automation a brand runs.
Billing had to exist before revenue
BIK.ai’s pricing is tied to AI-credit consumption. That meant they needed a billing system capable of tracking real-time usage before they had a single paying customer. Without that foundation, there would be no reliable way to calculate consumption, generate invoices, or monetize the platform as it scaled.
Managing two pricing models
BIK.ai combines recurring platform fees with recharge-based billing for broadcast campaigns and on-demand automations. Both pricing models needed to operate within a single system without requiring manual reconciliation between them.
Expanding across regions
As the company entered the United States, it needed separate billing accounts for India and the US while keeping finance operations lean.
Protecting recurring revenue
For a usage-based business, failed payments translate directly into lost revenue. BIK.ai needed an automated process to recover overdue payments without increasing operational overhead.
The solution
BIK.ai implemented Zoho Billing on the day it launched its product. The decision came down to two factors: enterprise-grade billing at startup-friendly pricing, and a self-service implementation that required no dedicated onboarding team. Three years later, the same billing foundation supports a $7 million ARR business.
API-driven usage billing
Zoho Billing integrates directly with BIK.ai’s product through APIs. When customers recharge credits, requests flow automatically through Zoho Billing and Zoho Payments to generate invoices, process payments, and update customer wallets, all without manual intervention. Volume spikes during broadcast campaigns do not disrupt the process.
Supporting multiple pricing models
Recurring platform fees and recharge-based usage billing operate within a single billing platform. Annual and semi-annual subscriptions run alongside on-demand recharges, allowing finance teams to manage both revenue streams without switching systems. Approximately 90% of billing operations are now automated.
Multi-region billing
When BIK.ai entered the United States, they were easily able to replicate the setup and adapt to regional compliance with minimal effort. New employees could quickly learn and adapt to the platform, regardless of their finance background.
Connected finance operations
BIK.ai uses Zoho Billing alongside Zoho Books and Zoho Payments. The three products work together, giving finance, engineering, and operations teams a unified view of billing, subscriptions, payments, and revenue.
Recovering revenue automatically
Zoho Billing’s dunning management automatically reminds customers about overdue invoices and retries collections when payments fail.

Benefits and Return on Investment
Building billing infrastructure from day zero allowed BIK.ai to focus on growing its AI platform instead of rebuilding finance operations as the business expanded.
- Revenue grew from zero to $7 million ARR in approximately 3 years.
- 90% of billing operations were automated.
- 95% payment recovery was done through dunning management and autocharges.

Looking forward
As AI products mature, usage-based and outcome-based pricing are becoming standard, with platform costs increasingly tied to the value AI actually delivers. For BIK.ai, that evolution is already underway. Having built its billing foundation from day zero, the company can adapt its pricing model without rebuilding the infrastructure underneath it.For AI startups evaluating their billing stack early, Nathani’s advice is direct:
“For AI startups, it’s a day-zero requirement to adopt software like this.”
