Invoice software for US businesses.

The US doesn't have a federal e-invoicing mandate. There is no national VAT. The IRS doesn't prescribe a specific invoice format. What you do have is a 50-state patchwork of sales-tax rules, the Commercial Invoice as the de facto B2B document, and accountants who care more about clean records than about which app produced them. Guliel is built for that reality.

The short version

There is no federal e-invoicing mandate in the United States. B2B invoices follow the Commercial Invoice format — flexible by federal standard, with state-level sales tax handled on top where it applies. Tax-ID numbers are not federally required on invoices, but most B2B accounting workflows expect an invoice number, dates, line items, totals, and sales tax itemised where it's charged.

We are not a sales-tax engine. For nexus determination, multi-state filing and full sales-tax automation, you'll want Avalara or TaxJar — we say this up front. Guliel handles the invoice document, the tax fields on the invoice, and the reporting on top.

US Commercial Invoice format

The fields Guliel includes on a US Commercial Invoice by default:

• Invoice label (recommended, not federally mandated).
• Sequential invoice number.
• Issue date and, where relevant, ship/service date.
• Seller business name and address (EIN/TIN optional — included where you provide it).
• Buyer name and address.
• Line items with description, quantity, and unit price.
• Sales tax itemised where applicable, by state and rate.
• Subtotal, tax total, grand total.
• Payment terms and instructions, with payment details auto-populated from your saved receiving accounts.

Receipts are auto-generated on payment. Issuance is sub-second once the invoice is composed. See /invoicing for the broader document-compliance picture.

Multi-state sales tax — what Guliel does and doesn't do

Sales tax in the US is administered by the states, not the federal government. Rates and rules vary — Oregon, Montana, New Hampshire and Delaware have no state sales tax; California layers state, county and district rates; Texas and Florida have origin/destination quirks; software-as-a-service is taxable in some states and not others.

What Guliel handles:

• Configurable tax lines on the invoice — set the state, the rate, the label. Multiple tax lines per invoice if you bill across jurisdictions.
• Sales tax shown separately by state, with totals broken out on the invoice itself.
• Tax by jurisdiction as a pre-built report — supplier/customer location, tax rate, total collected, period filters. The report your accountant actually wants at quarter end.
• Customer-level tax exemptions (e.g. resale certificates) — flag the customer, the invoice picks it up.

What Guliel does not handle:

• Nexus determination. Working out which states you have economic or physical nexus in is not our job. Avalara and TaxJar exist for this and they do it well.
• Sales-tax filing. Filing returns with each state's department of revenue is also not our job. Same recommendation.
• Live rate lookups by ZIP+4 at scale across every US jurisdiction. We don't pretend to.

If you're a freelancer or consultant primarily billing for services in one or two states, the tax fields in Guliel are usually enough. If you sell physical goods across 20 states with nexus exposure, pair Guliel with Avalara or TaxJar — they handle nexus and filing, we handle the invoice document and the reporting on top.

Where US businesses fit Guliel

The strong fit:

• Freelancers, consultants and agencies with US-based clients and occasional cross-border invoicing.
• SMBs running multiple LLCs or DBAs — Guliel is multi-org under one account, priced per organization, not per seat.
• Anyone wanting the bidirectional supplier flow: send orders to contractors and US vendors, those vendors invoice back, the invoice reconciles automatically.
• Teams who want one calm system for invoicing, expenses, supplier orders, reports and AI-driven automations — without the accountant-software complexity of QuickBooks. See /compare/quickbooks for the honest side-by-side.

The not-strong fit:

• US-only businesses that need full double-entry accounting, payroll integration, and 1099 generation under one roof. QuickBooks Online and Xero own that space — we don't compete there. Use Gusto for payroll.

Pricing

US businesses pay the same as everywhere else — Free, $20, or $99 per organisation per month. See /pricing. No per-seat charges. No payment-take-rate lock-in. Margin comes from the subscription, not from skimming a percentage off every transaction.

A note on payments: built-in payment processing is on the Guliel roadmap, not shipped today. US businesses typically keep Stripe or PayPal as a secondary tool until we add it. We mention this so you can plan around it.

FAQ

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

No. Unlike the EU, Singapore, or Japan, the United States has no federal e-invoicing mandate today. The Business Payments Coalition has run pilot programs on a US-based exchange framework, but adoption is voluntary. Guliel produces the standard US Commercial Invoice format that accountants and the IRS expect for record-keeping.

Does Guliel handle sales tax across all 50 states?

Guliel handles the invoice-level tax fields and the tax-by-jurisdiction report. It is not a full sales-tax engine and does not handle nexus determination or multi-state filing. For those, use Avalara or TaxJar alongside Guliel.

Do US invoices need to show an EIN or TIN?

Not federally. EIN/TIN are not required on US B2B invoices. Some customers ask for it on W-9s; some state-level sales-tax registrations expect a seller permit number on the invoice. Guliel lets you add and display those fields where relevant.

Can I migrate from QuickBooks?

Yes. We import customers, invoices and payment history. Chart of accounts and full ledger entries do not import — that's because Guliel isn't a full accounting platform. See the QuickBooks comparison at /compare/quickbooks for the honest version of what migrates and what stays.

Does Guliel work for multi-LLC structures?

Yes. Guliel is true multi-org under one account, with org-level permissions. Each LLC is its own organisation, with its own invoices, customers, suppliers, and reports. Pricing is per organisation, not per seat — so a one-person shop running three LLCs pays three Free or three Standard tiers, whichever applies.

What about 1099 contractors?

The supplier module covers the bidirectional flow — you send an order, the contractor invoices back, the invoice reconciles into your expense and report views. End-of-year 1099 generation itself is on the roadmap; today you can export supplier-spend reports and hand the totals to your accountant.
