Tax Infrastructure for Modular Finance
Michelle Valentine, co-founder and CEO of Anrok, on the modularization of the SaaS finance stack
Working across a modular finance stack is what turns tax software from a Stripe add on into system of record for revenue compliance. A growing SaaS company might bill in Chargebee, collect payments in Stripe and ACH, sync books to NetSuite or QuickBooks, and add headcount through Rippling. Anrok wins when it can pull all of that activity into one place, detect where tax is owed, calculate tax at invoice creation, and handle filings without forcing the customer to replace the rest of its stack.

The practical problem is fragmentation. Tax liability depends on every place revenue is created and every place the company has nexus, including employee locations. That means a tax tool has to ingest billing data, payment data, ERP data, and sometimes HR data, then map them into one filing calendar and return workflow.

This is also the main line between Anrok and Stripe Tax. Stripe Tax is simplest when most activity runs through Stripe. Independent tax layers matter once companies add other billing systems, other processors, marketplace revenue, or more complex B2B invoicing and remittance needs.
-
The broader market pattern is unbundling. Small companies often accept an all in one stack because setup is easy. As they move upmarket, finance teams pick separate tools for billing, payments, ERP, and reporting, which creates room for point solutions like Anrok to become the connective layer rather than a feature inside one platform.
The next step is for tax engines to become embedded infrastructure across the finance stack. As SaaS companies add global VAT/GST, physical products, and more sales channels, the vendor that plugs cleanly into every billing, payment, and ledger system will control a larger share of compliance workflow and become harder to replace.
