Compliant invoicing, country by country.

Most invoicing tools generate the same PDF for everyone and call it done. Revenue authorities don't. Singapore wants InvoiceNow. Germany wants XRechnung or ZUGFeRD. Brazil wants NF-e signed and registered. Japan wants a Qualified Invoice with the issuer's registration number. France is rolling out a mandate in September 2026. Belgium's B2B mandate is already live.

Guliel issues the right document for the country the invoice is for. Not a template with a flag toggled. The actual format the local tax authority expects. Global by default, with new countries shipping monthly.

Peppol AP — landing later 2026. Today we generate the country-correct document (PDF, XML, or hybrid). For jurisdictions whose mandate requires transmission via a Peppol Access Point — Singapore InvoiceNow, the Belgian and French mandates, parts of Germany's B2G flow — Guliel is becoming a certified Peppol AP later 2026. Until that's live, you'll submit the generated document through your existing AP or the relevant national portal. The document Guliel produces is the same one the AP relays; only the last-mile delivery channel differs.

How it works

Pick the customer, the items, the currency. The document type follows from the customer's country and the issuing organization's country. Payment details auto-populate from your saved receiving accounts. Issuance is under one second.

Country-modular document engine

Each country plugs in as an adapter — labels, tax rate types, document layout, electronic transmission format, statutory references. The same invoice generator runs everywhere. Adding a country is adjoining one adapter, not rewriting the core. That is why we can keep shipping countries monthly.

One organization, many markets

Run one org per legal entity. Bill SG GST on one, US sales tax on another, EU VAT on a third. Multi-org is native, priced per organization, not per seat. The bidirectional supplier flow and expenses work the same way across every org.

Receipt on payment, automatic

Mark an invoice paid — manually for now, since built-in payment processing is on the roadmap rather than shipped — and the matching receipt document is issued automatically. Country-correct, numbered correctly, sent if the automation is on. Nothing else to do.

Drafts, edits, credit notes, voids

Drafts don't deduct stock or trigger receipts. Once an invoice is issued, edits are governed by what the country allows — most jurisdictions require a credit note for material changes after issuance, not a silent rewrite. We default to that behaviour. Auditors thank us later.

Sent however the customer wants

PDF email, link to a public view, or pushed into the customer's Guliel inbox if they are also on Guliel. Status — sent, viewed, paid — updates regardless of channel. Direct Peppol-network delivery via Guliel-as-an-Access-Point lands later 2026 (see the callout above); until then, the structured XML the platform produces is yours to route through your existing AP or the national portal.

Pricing

Per organization, not per seat. Free for businesses doing up to 200 invoices a month — that covers a real freelancer. $20 / org / month lifts the cap to 5,000 invoices and unlocks unlimited reports. $99 / org / month goes to 50,000 and adds SSO, audit log, and priority support. Full table on /pricing.

We don't take a percentage of the invoices we issue. Margin comes from subscriptions. Payment processing is on the roadmap — until it ships, keep your Stripe or whatever you use today. We'll integrate.

What this isn't

We don't do full double-entry accounting. Use Xero or QuickBooks for the ledger. We don't run nexus determination or file your state sales tax — Avalara and TaxJar exist. We don't do payroll. Use Gusto. We do the invoice, the receipt, and everything that hangs off them.

FAQ

Which e-invoicing standards does Guliel support?

Peppol BIS Billing 3.0 (the backbone for most EU mandates and Singapore's InvoiceNow), XRechnung and ZUGFeRD for Germany, Factur-X for France, NF-e for Brazil, CFDI for Mexico, Japan's Qualified Invoice System, UK VAT invoices for MTD, and the US Commercial Invoice format. Global coverage, with new jurisdictions shipping monthly.

Does Guliel transmit invoices through a Peppol Access Point?

Not yet — Guliel is becoming a certified Peppol Access Point later 2026. Today the platform generates the Peppol-format XML payload (Peppol BIS Billing 3.0, XRechnung, etc.); transmission to the Peppol network goes through your existing AP or the relevant national portal. Per-country detail and chain-of-custody notes live on each country page (Singapore, Belgium, France, Germany).

How fast is invoice issuance?

Under one second for the canonical case — customer selected, items in the catalog, currency set. PDF generation, document numbering, country-specific formatting, and stamping the payment receiver block happen in that window. Slow cases (first-time country setup, large attachments) take longer the first time and cache afterwards.

Can I run multiple organizations under one account?

Yes. Multi-org is native, not a workaround. Each org has its own country, currency defaults, tax registration, document numbering, and team. Pricing is per organization, so a freelancer with two LLCs pays for two orgs — usually both on the free tier.

Will my existing customers, invoices, and receipts come over?

We import customers, historical invoices, and payment records from QuickBooks Online, Xero, Wave, FreshBooks, Invoice Ninja, and Zoho. Chart of accounts and ledger postings do not come over — we are not a full accounting system. The migration pages spell out what comes and what doesn't, by source tool.

Do I need a separate tool for compliance updates?

No. Country adapters update when the standard updates — XRechnung version bumps, Peppol BIS schema changes, Japan invoice number registry refreshes. You don't manage version files. We push the change; your next invoice uses the new one.
