Slingstone builds AI-first applications for the back office: AP Automation, Compliance, Mail, Expense, Treasury, Loans, Assets, Close and Recruit. Each one connects to the systems you already run and uses AI to do the work, not just track it.

Finance, accounting and operations teams at growing companies and multi-entity groups — and, for Compliance, beverage alcohol producers, importers, retailers and 3PLs.

No. Start with one application and add others when you're ready. They share the same login, data and AI, so each one you add makes the others smarter.

Pricing depends on the applications you use and your volume. Book a demo and we'll put together a quote for your business.

Legacy applications were built to record work that people do. Slingstone was built for AI to do the work — reading documents, applying rules, coding, routing and drafting — while people review exceptions and make decisions. It's also platform-agnostic, so you aren't locked into one vendor's ecosystem.

It's a suite of applications on one shared platform. Each application can be used on its own, and they share sign-in, permissions, documents, audit trail and AI.

Slingstone was designed around AI from the start. AI reads documents, checks rules, codes transactions, drafts filings and routes work. People set the guardrails, approve exceptions and make the decisions that matter.

Only where you allow it. AI earns autonomy task by task — first shadowing your team, then suggesting, then acting on proven, low-risk work. Payment releases, vendor bank changes and approvals always stay with people.

Yes. Every AI decision is recorded with its reasoning, the source it used and the model that made it, so controllers and auditors can see exactly what happened.

Yes. Slingstone connects to AI assistants through MCP, the open standard for linking assistants to business applications. Your team can ask questions and prepare work from the assistant they already use, under the same permissions as the app.

No. Your data is used to run your Slingstone applications and is not used to train public AI models.

Slingstone routes each task to the model best suited to it, and can switch models as better ones become available, so the platform improves without an upgrade project.

A way of introducing AI safely. For each task, AI starts in shadow mode, where its answers are compared to your team's. When it proves accurate, it moves to suggesting, and finally to acting on low-risk work. You can change the level for any task at any time.

Yes. Every AI task can be set to off, shadow, suggest or act, and the application works manually for anything you choose to keep manual.

Answer questions from your live data and prepare work — such as drafting a bill coding or summarizing upcoming deadlines. Approvals, payment releases and other sensitive actions are reserved for people inside Slingstone.

On Microsoft Azure, with secrets and credentials held in Azure Key Vault and sign-in through Microsoft Entra ID single sign-on.

A person releases every payment, the approver and the releaser must be different people, vendor bank changes require verified human approval, and inbound email is checked for look-alike senders and domains.

Yes. Every action is written to a tamper-evident, hash-chained audit log, and sensitive changes to roles and settings go through an approved change request.

Only users you authorize. Roles are scoped by company, so a user can be limited to specific entities and actions.

Bank details are masked in the application and stored in a secure vault. Any change requires verified approval by a person before it can be used for a payment.

Documents and records are archived under retention policies you control, including long-term retention for financial and inventory-related records.

ERPs and accounting systems including NetSuite, QuickBooks Online and Intuit Enterprise Suite; commerce platforms including Shopify and Toast; bank accounts and corporate and personal cards at more than 12,000 financial institutions; Microsoft 365; and AI assistants through MCP. Other systems connect through our API and AI-mapped file imports.

Slingstone is platform-agnostic. When you change systems, your Slingstone applications and history come with you.

Yes. Slingstone reads your chart of accounts, vendors and dimensions, and writes bills, journal entries and attachments back to your ledger.

Yes. Load history from your previous ERP or AP tool by direct connection or file upload; AI maps the columns for you to confirm.

Yes. Slingstone has a REST API, and MCP access for AI assistants and agents.

By a dedicated email address for each company, by upload, or from paper mail scanned by Slingstone Mail. Every document is checked for duplicates when it arrives.

Yes. Run any number of companies from one login, with company-scoped roles, intercompany workflows and consolidated views.

No. AI reads any invoice layout, including line items, without templates to build or maintain.

AI suggests GL accounts and dimensions based on the vendor, the invoice and how your team has coded similar bills, with a confidence score and the reasoning behind each suggestion.

Yes. Approvers get notified by email or Microsoft Teams and can act through secure, signed links.

Payments are planned on a prioritized worksheet and released by a person — by ACH bank file, card, or check. Checks can be printed on your own check stock or printed and mailed for you. Tax and government payments can require an extra level of approval.

Yes. Print checks on blank check stock with the MICR line, your logo and signature, and send positive pay files to your bank.

Yes. Slingstone can print and mail checks for you by first-class or certified mail, with tracking and delivery confirmation.

Both. It checks orders in real time, tracks licenses and limits, and prepares, files and schedules payment for returns once you approve them.

Yes. Slingstone Compliance checks orders at Shopify checkout and builds your returns from Shopify sales — along with your wine club, tasting room, wholesale and 3PL orders.

Yes. You see your own compliance and each client's in one place, with order gatekeeping before anything leaves the warehouse and alerts when a client's license is close to expiring.

Direct-to-consumer e-commerce, wine club, tasting room, wholesale and three-tier distribution, and 3PL fulfillment — all counted toward the same limits and reports.

Yes. Federal and state licenses, permits, bonds and registrations live in one register, with renewal alerts at 90, 60, 30 and 7 days and automatic order holds if something lapses.

An AI agent monitors regulatory sources and proposes updates to the rules database, which are reviewed and approved by people before they take effect.

Yes. Slingstone Compliance receives email and postal mail from the TTB, state alcohol boards, departments of revenue and other regulatory and tax agencies. AI reads each item, matches it to the right entity, license or filing, drafts a response with supporting records, and — once you approve — sends it by email, first-class mail or certified mail. Every item is tracked until it's resolved.

All of it — letters, statements, invoices, checks, tax and legal notices, and packages. Point all your company mail to your Slingstone address.

Yes. Choose from 53 real street addresses in 53 cities across 44 states and Washington, D.C. — street addresses with suite numbers, not P.O. boxes.

AI identifies it, summarizes it and turns it into the right action: a specific task assigned to the right person, a bill in AP Automation, or a check deposit. You can also forward, archive or securely shred it.

Yes — a real street address with a suite number, not a P.O. box, in the location you choose.

Yes. Checks are deposited to your bank account, with remittance details captured so payments can be applied.

Yes. AI identifies who each piece is for and assigns it as a task to the right person, based on rules you set by sender, type, company or recipient.

It keeps every contract and lease in one place, uses AI to extract terms, dates and notice requirements, tracks renewals and obligations, and generates and sends legal notices when they're due.

AI drafts the notice from the contract's own terms and notice clause. After a person approves it, Slingstone sends it by email, first-class mail or certified mail with return receipt, and stores proof of sending and delivery with the contract.

Not if they're in Slingstone. Renewal and notice windows are tracked with owners and alerts, and auto-renewal warnings arrive before the notice deadline passes.

Corporate and personal cards at more than 12,000 financial institutions through live feeds, plus statement imports for issuers including American Express, Chase, Citi and Capital One.

Yes. Slingstone installs on any phone as a web app, so receipts can be captured on the go, or forwarded by email.

Yes. Treasury shows a daily cash position by entity and account, from live feeds or bank files that AI reads for you.

Term loans, lines of credit and intercompany notes, with fixed or variable rates, from both the borrower and lender side.

Yes. Slingstone Contracts scans your bill history for recurring payments that look like contracts or leases, so you can add them to the repository.

It runs reconciliations and checks across your Slingstone data, explains any exceptions, and tracks the close checklist through sign-off.

Staffing and recruiting firms, and in-house talent teams, that want one AI-first platform for applicant tracking, sourcing, engagement and onboarding.

They search and match candidates, screen applicants against job criteria, transcribe calls and write notes, format resumes, build submission packets, enrich profiles and run multi-step outreach — with recruiters reviewing every submission.

Yes. Jobs can be imported from VMS platforms in real time and candidates submitted back without leaving Slingstone.

Yes. Candidates pick a time from synced recruiter and client calendars, and reminders go out automatically by email and SMS.

Implementation is AI-guided: AI reads your connected systems and documents, proposes your configuration and walks your team through each step, so most of the work is review rather than data entry. We'll show you the process in a demo.

Book a demo and we'll show you Slingstone working with your systems and workflows.

Usually not much. Sign-in uses your Microsoft account, and connections to your systems are set up with guided steps.

Yes. Add companies, users and applications whenever you're ready.

Our team helps you get set up and is available when you need a person. Talk to us during your demo about the level of support that fits your business.

Instead of consultants and setup spreadsheets, AI does the heavy lifting. It connects to your accounting system and reads your chart of accounts, vendors and dimensions; reads documents you upload, like licenses, contracts and loan agreements; imports your history with AI column mapping; and proposes your configuration — approval rules, coding, policies and schedules. Every value AI sets is marked with its source so your team can review and change it, and a step-by-step guide shows what's done and what's left. Before go-live, AI can run in shadow mode so you can compare its work with your team's.

Yes. Everything AI configures is visible in Setup, marked as set by AI with its source, and any change you make takes priority over later AI suggestions.
