Tax calculation engine
Calculate sales and use tax with jurisdiction, situs, and rate logic. Compare expected treatment to tax collected or accrued and produce filing-ready numbers for review.
All plans
Prophit.ai is a modular sales and use tax platform that helps small businesses, finance teams, and tax departments manage sales tax, use tax, exemption certificates, and filing-ready return preparation in one controlled environment.
What it does
Prophit.ai combines a sales and use tax calculation engine with the workflows that surround it. The platform ingests transaction data, applies jurisdiction and rate logic, supports human review, and prepares filing-ready outputs. Core compliance modules, shared Upload Center and Returns Centers, and optional intelligence tools work together under organization and location scope.
The platform is organized around organizations and locations. Each location can activate the modules your plan includes, so a growing business or multi-location operator runs the same disciplined workflows everywhere while keeping data and obligations scoped correctly.
Tax-relevant data enters through Upload Center and configured connectors such as QuickBooks and Stripe in Sales Tax Compliance. Modules transform that data into reviewable determinations, exception queues, certificate coverage, and filing-ready packages. Returns Centers give managers a cross-period view of what needs attention before remittance or portal filing.
Prophit.ai is built for operators who need defensible tax results: a founder handling sales tax for the first time, an accountant closing monthly books, or a tax director managing multiple locations. Every significant determination can tie to source transactions, reason codes, and supporting documents. AI and OCR accelerate extraction and classification; human review remains the control layer for material decisions.
Why it matters
Sales and use tax work carries volume, jurisdiction complexity, and audit scrutiny. Spreadsheets and disconnected tools break down as transaction counts grow and nexus expands. Prophit.ai replaces ad hoc review with a platform where calculation, exemption evidence, and return preparation share the same scope and context.
Buyers evaluating sales tax compliance software need more than a rate calculator. They need a tax engine plus an operating model. Prophit.ai supports that model from first data import through filing-ready outputs, with modular expansion into analytics, AI assistance, and advanced add-ons as programs mature.
Where it fits in the platform
Prophit.ai sits between source systems (ERP, billing, AP, e-commerce) and filing or remittance. It is not a replacement for your GL or billing platform. It is the tax operations layer that makes those systems auditable for indirect tax.
Public product pages explain positioning and plan fit. This documentation library explains how the platform works. Developer integrations are documented at /api-access.
