Explore the accounting-firm workflowSales tax software should help get the right numbers onto the right returns, on time, in the places where you have obligations.
That means supporting the work before and after a calculation: data, obligations, review, filing support, use tax, exemption certificates, and evidence.
Data ingestion from the records your business actually uses
Nexus and obligation awareness without turning the page into a legal treatise
Taxability, rates, collected tax, expected tax, variances, and remittance review
Return-ready outputs, workpapers, portal-upload files, or customer-operated e-file handoffs where enabled
Use tax, exemption certificates, review controls, and evidence trails
Taxing-authority notice intake, due-date tracking, and customer-controlled response worksheets
Nexus Monitoring evaluates sales and transaction counts against effective-dated state thresholds for the current and prior year. It separates physical and economic nexus, shows the data-through date, and marks approaching, met, below-threshold, and needs-review states so incomplete data never looks like zero exposure.
Marketplace-facilitator treatment uses explicit channel and jurisdiction responsibility facts. Collection, remittance, reporting, merchant-of-record, seller, and facilitator roles stay reviewable; ambiguity blocks a conclusion instead of allowing a provider name to decide it.
Scope: US sales and use tax. Prophit.ai is not a global VAT, GST, or e-invoicing platform.
Buyers do not usually think in software packaging language. Start with the way your business actually handles sales and use tax work today.
A simple, low-cost way to import sales data, calculate tax, monitor obligations, and generate return-ready outputs.
StarterMulti-user and multi-location workflows for calculation, reconciliation, use tax, returns, and filing support.
ProfessionalA configurable sales and use tax platform with integrations, AI-assisted review, evidence trails, permissions, and enterprise controls.
EnterpriseA more connected workflow that reduces fragmentation between data, decisions, returns, review, and evidence.
Professional or EnterpriseBring sales activity into a focused workspace.
Coordinate recurring work across users and locations.
Connect systems, permissions, review, and evidence.
For small sellers, the first question is often simple: what does this cost, and what do I actually get for that price? Sales tax software should be clear about whether it only calculates tax, or whether it helps turn sales data into return-ready numbers and filing support.
At minimum, small sellers need a way to import sales data, calculate tax correctly, and generate the return-ready output they need.
Growing businesses do not usually struggle because multiplication is hard. They struggle because the workflow becomes too broad for one person, one spreadsheet, or one basic tool.
The inflection point is not only revenue. It is the moment your team can no longer confidently say that every sale and purchase has been reviewed for sales and use tax consequences.
Start ProfessionalEnterprise sales tax software is not primarily about multiplying a transaction amount by a rate. The hard part is everything around the calculation: data, decisions, workflows, review, filings, evidence, permissions, and controls.
An ERP may hold the data, but that does not mean sales tax is handled. Prophit.ai can support practical integration patterns at the level the organization is comfortable with, from controlled periodic data access to deeper workflow integration where appropriate.
Plan a meetingAI is not the user's goal. Accurate, timely filing is the goal. Prophit.ai uses AI-assisted workflows where they can help normalize data, extract tax facts, classify transactions, prioritize review, and explain variances.
Prophit.ai does not ask buyers to trust a black box. Reviewable recommendations, evidence, and workflow control support human tax judgment.
AI-assisted normalization of messy source data
Extraction of tax facts from transactions, invoices, and files
AI-assisted classification and context review
Prioritization of exceptions, material items, and lower-confidence issues
Variance explanations that support human-reviewable decisions
Reduced implementation friction through more flexible data handling
A calculation API, a filing service, and a review workspace solve different problems. Compare the same scope: purchasing use tax, certificates, integrations, reviewer control, and who submits the return.
Every plan includes sales tax compliance, purchasing (use) tax compliance, and both exemption certificate managers. No per-state fees, no per-filing credits, no certificate add-on.
| Plan | Price | Scope | Includes |
|---|---|---|---|
| Free Trial | $0 for 30 days | 1 user · 1 location | Sales Tax Compliance, Purchasing Tax Compliance, sales and purchasing exemption certificates |
| Starter | $199/month flat | 1 user · 1 location | Everything in the trial, self-serve, standard support |

Before choosing sales tax software, ask whether the tool supports the outcome: right numbers, right returns, on time, in the places where you have obligations.

Buyers searching for sales and use tax compliance software need one platform that connects sales-side calculation and filing, purchasing-side use tax review, exemption certificate evidence, API-driven calculation where configured, and filing-ready period-close workflows.
Sales tax calculation, obligation tracking, collected tax reconciliation, filing-ready returns, and period-close review — with exemption certificate context tied to tax treatment where configured.
Use tax review, vendor-charged tax comparison, exemption-aware purchasing workflows, and filing-ready use tax outputs connected to the same compliance platform.
Prophit.ai connects sales tax, use tax, exemptions, analytics, AI-assisted review, and filing support in a modular workflow. A small seller can start focused. A growing team can add collaboration and visibility. An enterprise tax team can configure controls and review depth.
Software should augment tax professionals, not bury them under configuration, exports, and manual cleanup.
Sales and use tax compliance software connects sales-side calculation and filing, purchasing-side use tax review, exemption certificate evidence, and filing-ready period-close workflows in one platform. Prophit.ai is modular so teams can start with the workflows they need and expand as complexity grows.
Use the use tax software page when purchasing-side review, vendor-charged tax, or accrual exposure is the primary question. Use the sales tax filing software page when period-close filing support, collected tax reconciliation, and filing-ready outputs are the focus. Use the sales tax API page when real-time calculation inside checkout, billing, or ERP systems is the priority. This page is the category overview that connects those workflows.
Indirect tax work rarely stays in one lane. Exemption status affects sales and purchasing decisions, use tax exposure shows up in AP review, filing workflows need the same evidence, and API calculation should connect to review and filing-ready outputs instead of living in a separate silo.
Sales tax software helps a business turn sales activity into return-ready numbers, filing support, workpapers, and records. The best fit depends on the complexity of the business, not only its size.
Possibly. Sales tax problems can happen entirely inside a home state if a seller registers or collects tax but does not complete the filing and remittance workflow.
No. Ecommerce can create sales tax complexity, but physical locations, services, invoices, exempt customers, purchases, and multi-location operations can also create sales and use tax work.
Sales tax is generally charged to customers on taxable sales. Use tax is generally self-assessed when tax was not collected, or when a purchase needs review. Prophit.ai treats sales tax and use tax as connected parts of the same compliance picture.
Prophit.ai prepares returns, workpapers, portal-upload files, and supported e-file handoffs for your reviewer. Your organization submits the return and remits the tax. Prophit.ai does not file, transmit a return, move money, or represent you before a taxing authority.
Yes. Nexus Monitoring compares state-by-state sales and transaction counts with effective-dated thresholds for the current and prior calendar year, distinguishes physical from economic nexus, and surfaces approaching, met, below-threshold, and needs-review states. The dashboard records the data-through date so missing or stale activity is not presented as zero.
Marketplace responsibility is carried as an explicit, effective-dated fact. Seller, facilitator, merchant-of-record, collection, remittance, and reporting roles remain reviewable by channel and jurisdiction; unknown or contradictory responsibility fails closed instead of being inferred from a marketplace name.
Yes. Tax Notices accepts supported uploads and forwarded .eml files, records OCR and classification status, separates overdue, due-soon, and due-date-unavailable items, and prepares a response worksheet. Your team reviews and sends any response; Prophit.ai does not contact the authority or represent you.
No. Prophit.ai is deliberately focused on US sales and use tax, including state and local jurisdictions, marketplace-facilitator rules, exemption evidence, nexus monitoring, and filing-ready workflows. It is not positioned as a global VAT, GST, or e-invoicing platform.
No. Prophit.ai is designed to support owners, accountants, finance teams, and tax professionals with data, calculation, review, returns, and evidence. Software should augment tax judgment, not replace it.
AI is not the goal. Accurate, timely filing is the goal. AI-assisted workflows can help normalize data, extract tax facts, classify transactions, explain variances, and present reviewable recommendations.
Starter is usually the fit for individuals and small sellers. Professional fits growing teams with more users, locations, and workflows. Enterprise fits complex tax operations that need configured workflows, controls, and support.
Start focused with Starter, add team workflows with Professional, or talk with Prophit.ai about configured Enterprise operations.
