America's Smartest ERP for Growing Businesses.

Since the 2018 Wayfair decision, selling into a state can create sales-tax obligations without a physical presence once you cross that state's economic-nexus threshold. A modern ERP has to compute tax by ship-to address at the state, county and city level, track your exposure state by state, respect marketplace-facilitator rules, and produce filing-ready reports per jurisdiction. Tellency applies destination-based rates on every order and reports by jurisdiction so your filings come from the ledger, not a spreadsheet.

Hiring across state lines brings state withholding, state unemployment insurance, local taxes in places like New York City and Pennsylvania, and different paid-leave rules. Contractors add 1099-NEC reporting on top of W-2s. Tellency runs payroll on the same ledger as the rest of the business, so wages, employer taxes and remittances post once and year-end forms are generated from data you have already reconciled.

Growing companies end up with more than one entity — an operating company and a holding company, or a second state with its own LLC. You need entity-level books, intercompany eliminations and a consolidated view, plus revenue recognition that follows ASC 606 for anything sold on a subscription or delivered over time. Tellency keeps separate books per entity with a consolidated reporting layer and a complete audit trail of every posting and approval.

The subscription is rarely what makes ERP expensive; the implementation is. Traditional mid-market systems are quoted in months and billed in consultant hours, and the business runs on spreadsheets in the meantime. Tellency is configured to your American business on a fixed scope — chart of accounts, tax rules, modules, user roles and data migration from QuickBooks, Sage or spreadsheets — and goes live in one to four weeks. Ask any vendor for two numbers before you sign: the all-in cost to go live, and the week you will actually be running month-end in the new system.

Two kinds of AI live in Tellency. Nexus AI answers questions about your own data in plain English — 'show me overdue receivables over 60 days by customer' — and builds the report on the spot. AI agents go further: they can prepare bank reconciliations, draft journal entries, chase overdue invoices and flag stock that needs reordering. The rule that makes this safe is simple and enforced in code: every posting to the ledger waits for a human approval, and every amount must trace to a source document — a bank line, an invoice, a purchase order. The AI proposes; a person with authority approves; the audit trail records both.

Most growing businesses outgrow entry-level accounting software in the same ways: inventory lives in a spreadsheet next to the books, a second location or entity needs its own set of numbers, payroll runs in a separate tool and is re-keyed, month-end takes two weeks because sales tax is reconciled by hand, and nobody can answer 'what is our margin by product line' without an export. In the US the tipping point is usually the first year with nexus in three or more states or the first acquisition of a second entity. An ERP puts sales, inventory, purchasing, payroll and accounting on one ledger so those questions have live answers. NetSuite and Dynamics deliver that, typically at enterprise implementation cost and timelines. Tellency's position is mid-market capability — multi-entity, multi-state tax, manufacturing, POS, payroll — configured to a business in weeks, at small-business pricing.
