Invoice and accounting software for US businesses

Guliel is accounting and finance-operations software with a double-entry general ledger. For a US business it issues invoices, receipts, credit memos and debit memos as PDF with your EIN and a sales-tax line, captures expenses, and runs purchase orders and payroll on one engine, posting invoices, payments, approved expenses and payroll to the same ledger. It does not determine sales-tax nexus, file state sales-tax returns, issue 1099s or calculate US payroll withholding. Those stay with a sales-tax service, a payroll provider or your CPA.

US invoicing rules, in short

• No federal e-invoicing mandate. The Business Payments Coalition has piloted a voluntary e-invoice exchange framework; nothing requires it. Guliel issues PDF documents; structured e-invoice output is planned.
• No national VAT and no IRS invoice layout. The IRS expects records that support your income and deductions, not a set format.
• Sales tax is set by states and localities. Alaska, Delaware, Montana, New Hampshire and Oregon have no statewide sales tax (Alaska allows local ones). Elsewhere, rates and what is taxable vary by state, county and city.
• A "commercial invoice" is a customs document for imported or exported goods, with fields such as country of origin and tariff classification. Guliel issues sales invoices, not customs invoices.

What a US invoice from Guliel shows

US organisations get Guliel's North American format (live):

• Your logo, business name, EIN (formatted XX-XXXXXXX) and state.
• INVOICE, RECEIPT, CREDIT MEMO or DEBIT MEMO, with a sequential number allocated at issue and a US-format date.
• Bill To: the customer's name, address, email and tax ID; due date and currency.
• Line items (description, quantity, unit price, amount, SKU when set), then subtotal, sales tax with its rate, and total due, calculated from the lines.
• An optional payment page with your saved bank details: ABA routing and account number for ACH or wire, SWIFT/BIC and IBAN for international wires.

Recording a payment issues the receipt automatically. Documents can be in USD or another currency, with the exchange rate stored. More at /invoicing.

Sales tax: what Guliel does and doesn't do

Does (live):

• Keeps your state and one sales-tax rate (0 to 15%) on the organisation profile and adds it to each taxable invoice as one sales-tax line. Receipts add no new tax.
• Charges no sales tax when the organisation is marked exempt or has no rate set. Your state of incorporation doesn't decide it.
• Runs a tax report by month, quarter or year with US sales-tax labels, and a tax-transactions list filtered by date, customer and rate.

Doesn't:

• Work out where you have economic or physical nexus.
• Look up rates by address or ZIP code, or put more than one jurisdiction's rate on an invoice.
• Store customer exemption or resale certificates, or file sales-tax returns.

If you bill services from one state, one rate usually covers it. If you ship goods into many states, the single rate is a real limit: services such as Avalara or TaxJar handle nexus, rates and filing, and Guliel has no connector to either today.

The ledger

Guliel keeps a double-entry general ledger on a fixed chart of accounts (live). It is computed from the same document lines as receivables and payables, so issued invoices, recorded payments, approved expenses and payroll runs land in it without a sync. Your accountant posts manual journal entries, which must balance, and reads the trial balance, balance sheet, general ledger, income statement and cash flow. A manager sets the books lock date, and the ledger exports as CSV. Custom accounts are planned. Details at /product/accounting.

Guliel does not prepare or file federal or state tax returns; your CPA works from the trial balance and reports. See how Guliel works with accountants.

Expenses, contractors and 1099s

Bills come in by scan (OCR, with AI picking a category from your own list) or from a connected Gmail, Outlook, IMAP or POP3 inbox (live). Each captured expense waits for a person's approval before it reaches the ledger.

For contractors and vendors, Guliel keeps supplier records with their tax ID, sends purchase orders, and links each supplier invoice to the order it bills (live). A supplier that accepts your invitation with its own Guliel organisation sees your orders and can invoice against them. At year end, the Supplier Spend report and the expense CSV export give your accountant spend per payee. Guliel does not collect W-9s or generate 1099-NEC or 1099-MISC forms.

Payroll

Guliel keeps HR records and runs a generic payroll profile with payslip PDFs that post to the ledger (live). It does not calculate federal or state withholding, Social Security or Medicare, or file Form 941 or W-2s; Singapore is the one statutory payroll it runs today. A US business can run payroll through a US provider and post the summary to Guliel as a journal entry. See /product/payroll.

Running Guliel beside QuickBooks or Xero

You don't have to switch on day one. Issue documents, capture expenses and work with suppliers in Guliel while your current tool stays in place, and export Guliel's ledger as CSV for your accountant (live). Automations then take over routine steps, with 14 triggers including overdue invoices and schedules (live). Move fully when you're ready.

Imports today: customers from a spreadsheet on Guliel's template (name, tax ID, email, phone, address, city), checked and staged for review before anything is saved (live). There is no importer for QuickBooks, Xero, Zoho, Wave, FreshBooks, Invoice Ninja, Stripe or Shopify; connectors for all eight are planned. History stays in your old tool or its exports. Step by step: /migrate/from-quickbooks. Side by side: /compare/quickbooks.

Who it fits

• Consultants, agencies and service businesses billing from one state.
• Owners with several LLCs: one login, each LLC its own organisation with its own documents, ledger and roles (manager, contributor, viewer).
• Businesses that buy from contractors and vendors through purchase orders.
• Teams that want AI to do the work: any MCP client (Claude, ChatGPT, Copilot) connects through OAuth 2.1 and acts within the user's role and scopes, and a built-in AI companion runs in the app (live). See /mcp.

Less of a fit today: multistate sellers of goods who need destination rates, businesses that need bank feeds and reconciliation (not built yet), and anyone who wants US payroll tax and 1099 filing in one product.

Pricing and payments

Per organisation, not per seat, and the same in every country. Published prices: Free at $0 (200 invoices, 100 expense scans, 10 reports and 5 automations a month), Standard at $20 and Premium at $99 per organisation per month. Paid plans are not on sale yet. See /pricing.

Guliel does not process payments. Keep Stripe, PayPal or your bank and record each payment against its invoice; the receipt follows. PayPal payment links are built but not switched on.

FAQ

Is Guliel accounting software or an invoicing tool?

Accounting software. Guliel has a double-entry general ledger with journal entries, a trial balance, a balance sheet, an income statement, a cash flow statement and a books lock date. Invoicing, expenses, purchasing and payroll run on the same engine, and invoices, payments, approved expenses and payroll post to that ledger.

Is there a federal e-invoicing mandate in the US?

No. The Business Payments Coalition has piloted a voluntary e-invoice exchange framework, but nothing requires it. Guliel issues PDF invoices today; structured e-invoice output is planned.

Does Guliel calculate sales tax for every state?

No. Guliel applies the one sales-tax rate on your organisation profile and reports sales tax by period. It does not determine nexus, look up rates by address or file state returns; a sales-tax service or your accountant does.

Do US invoices need an EIN?

No federal rule requires an EIN on an invoice. Guliel prints your EIN when you add it to your organisation profile, and prints a customer's tax ID when you have it.

Can I move from QuickBooks to Guliel?

Yes, in stages. Customers come across by spreadsheet on Guliel's template, your accountant posts opening balances as a journal entry, and new documents are issued in Guliel. There is no QuickBooks importer today; a connector is planned.

Does Guliel work for several LLCs?

Yes. One login can hold several organisations, each with its own documents, ledger and user roles. Pricing is per organisation, not per seat.

Does Guliel issue 1099s or run US payroll?

Guliel runs basic payroll with payslips that post to the ledger, but it does not calculate US withholding, file payroll taxes or generate 1099s. The Supplier Spend report gives your accountant the year's totals per contractor.
