Slingstone builds AI-first applications for compliance, finance operations, mail and recruiting — applications that do the work instead of waiting for you to do it. It plugs into the systems you already run and gets smarter every day you use it.
Our AI knows every application, integration and feature. Ask it anything.
The big vendors got comfortable. Renewals went up, roadmaps slowed down, and your team kept doing the work the application was supposed to do.
Use one application or the whole suite. Each one is built AI-first, and they share the same intelligence about your business — so a scanned bill in Mail becomes a coded invoice in AP without anyone touching it.
Bills in. Books updated. Nobody typed a thing.
Accounts payable automation that captures, codes, routes and posts invoices to your accounting system or ERP.
Beverage alcohol compliance, handled.
Direct-to-consumer, wholesale and 3PL compliance that checks every order, files every report — and receives and handles every email and letter from regulators and tax agencies.
All your mail. One inbox. Handled.
Every piece of business mail — letters, statements, checks, notices and packages — arrives at your Slingstone address, is scanned, read by AI and turned into the right action for the right person.
Every contract tracked. Every notice sent on time.
Contracts and leases tracked from signature to renewal — with AI that reads the terms, watches the dates, and generates and sends legal notices by email, regular mail or certified mail.
Expense reports nobody has to chase.
Company and personal cards, receipts and reimbursements — matched, policy-checked and posted automatically.
Know your cash. Move it smarter.
Cash position, payment planning and intercompany sweeps across every entity and bank account in one view.
Debt schedules that maintain themselves.
Upload a loan or lender agreement and AI builds the schedule — interest, payments, covenants and journal entries included.
Fixed assets and prepaids on autopilot.
Depreciation and amortization schedules built from your invoices — and posted every month without a spreadsheet.
Month-end, without the all-nighters.
An AI closing checklist that does the reconciliations it can, flags what it can't, and lets you ask your books questions in plain English.
A recruiting platform that actually recruits.
An AI-first applicant tracking system for staffing and recruiting teams — sourcing, screening, engagement and onboarding on one platform.
Most vendors bolted a chatbot onto applications designed in another era. We started over.
Agents handle the repetitive tasks end to end — reading documents, checking rules, coding transactions and filing reports.
Every decision comes with the reasoning and source behind it, so your controllers and auditors can see exactly what happened and why.
Set the guardrails, approve the exceptions, and let the routine run on its own. The more you use it, the less it needs you.
Traditional back-office software takes months of consultants, workshops and data mapping. Slingstone's AI does the heavy lifting — your team reviews and approves.
Link your accounting system, banks and other systems. AI reads your chart of accounts, vendors, dimensions and history.
AI reads the documents you upload — licenses, contracts, loan agreements — and proposes approval rules, coding, policies and schedules.
Every value AI set is marked with its source. A step-by-step AI implementation guide shows what's done, what needs you, and what's next.
AI runs alongside your team first, so you can compare results before it takes on real work.
Slingstone speaks MCP — the open standard for connecting AI assistants to business applications. Ask Claude, ChatGPT, Gemini or Grok what's due this week, why a bill was coded the way it was, or which licenses expire next quarter, and get answers from your live Slingstone data.
Query bills, payments, cash, licenses and filings from the assistant your team already has open.
Assistants can prepare and propose work. Approvals and payment releases stay with people, under the same permissions as the app.
Claude, ChatGPT, Gemini, Grok — or any MCP-compatible assistant or agent your company adopts next.
Slingstone isn't married to any one platform. We connect to the ERP, accounting, commerce, banking and warehouse systems you already run — and when you change systems, we come with you.
Two-way sync of bills, journals, vendors, charts of accounts and attachments.
Orders, payouts and customer data for compliance and cash application.
Live balances and transactions from bank accounts, corporate cards and personal cards at more than 12,000 financial institutions — plus payment and bank files.
Use Slingstone from the AI tools your team already works in, through the Model Context Protocol.
Sign in with your company account, get notified where you work, archive where you store.

David didn't win by being bigger. He was faster, more precise, and brought the right tool.
That's how we build. We look for markets where a few large vendors have grown comfortable — and we give their customers something better.
The most common ones are below. For anything else, or see the full FAQ.
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. 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.
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.
Both. It checks orders in real time, tracks licenses and limits, and prepares, files and schedules payment for returns once you approve them.
All of it — letters, statements, invoices, checks, tax and legal notices, and packages. Point all your company mail to your Slingstone address.
