KipBill vs Billin: The Honest Comparison for Freelancers & Small Business (2026)

Billin is one of the most popular invoicing platforms in Spain, with over 180,000 users. Its pitch is straightforward: simple invoicing for freelancers and small businesses, no ERP complexity, no accounting headaches. It is VeriFactu compliant, supports TicketBAI and FACe, and has carved out a solid position in the Spanish market.

But Billin was built for Spain. If you are a freelancer or small business that works internationally — billing clients in different currencies and languages — or if you want AI-powered features that save you real time every week, then it is worth comparing Billin with KipBill in detail.

Pricing: Free vs €6.6/month minimum

Billin offers a free plan, but it is extremely limited — very few invoices per month, no quotes, no expense tracking. For real functionality, you need a paid plan.

Billin's pricing (annual billing):

Plan	Price	Key limits
Básico	€6.6/month	Limited invoices, basic features
Pro	€12.5/month	More invoices, expenses, reports
Ilimitado	€20/month	Unlimited invoices
Plus	€83.3/month	Multi-company, premium support

KipBill's pricing:

Plan	Price	What You Get
Free	€0/month	Unlimited invoices, unlimited quotes, 5 clients, 3 templates, AI assistant (10 messages), receipt scanning
Starter	€3/month	50 clients, 8 templates, unlimited emails, auto-reminders, 30 AI messages
Pro	€5/month	Unlimited everything, 25 templates, API, e-signatures, multi-user, 100 AI messages
Business	€12/month	Everything in Pro + advanced AI assistant, team management, 200+ AI messages

A freelancer paying Billin Pro (€12.5/month = €150/year) could use KipBill Pro for the entire year and save over €90. And with KipBill Free, you get unlimited invoices and quotes at zero cost.

AI Assistant: The Feature Billin Does Not Have

This is where KipBill stands apart from Billin — and from every other invoicing tool in the Spanish market.

KipBill includes an AI assistant that understands natural language in 12 languages. You can:

• Create invoices by voice: "Create an invoice for Smith & Co, website redesign £4,500, 20% VAT" — done in seconds
• Create invoices by chat: Type what you need in plain language
• Scan receipts with AI: Take a photo of any receipt — the AI extracts every line item, calculates tax, and creates the expense automatically
• Ask questions: "How much did I invoice last quarter?" "Which clients have overdue payments?"

Billin has no AI functionality whatsoever. No voice commands, no chat assistant, no intelligent data analysis. It is a traditional invoicing platform — reliable but not innovative in this regard.

For a freelancer who invoices 10-30 clients per month, the AI assistant alone can save hours of manual data entry every week.

Receipt Scanning: Line-by-Line vs Basic Data

Both KipBill and Billin let you digitize receipts and expenses. But the implementation is fundamentally different.

Billin extracts basic data from receipts: vendor, date, total amount. It works for quick expense logging.

KipBill's receipt scanner goes much further:

• Extracts every individual line item with description, quantity, and unit price
• Detects different tax rates per item (critical for receipts with mixed VAT rates — 0%, 5%, 20%, etc.)
• Reads the tax breakdown section at the bottom of the receipt for accurate totals
• Detects the currency automatically (EUR, USD, GBP, JPY, etc.)
• Pre-fills the expense form with all data — you just review and save

For example, scan a supermarket receipt with 14 items across three different VAT rates, and KipBill will extract each product with its correct tax rate, matching the exact totals from the receipt's breakdown. Billin captures only the total.

International Capabilities: 12 Languages, 30+ Currencies

Billin is built for Spain. It works in Spanish, invoices in euros, and complies with Spanish tax regulations. For a freelancer working exclusively within Spain, this is enough.

KipBill was built international from day one:

Feature	KipBill	Billin
Languages	12 (EN, ES, FR, DE, IT, PT, NL, PL, JA, KO, ZH, AR)	1 (Spanish only)
Currencies	30+	EUR only
Invoice templates	25 industry-specific	Generic
Client portal	✓ Free	Not available

If you work with international clients — a developer billing a US startup in USD, a designer invoicing a London agency in GBP, a consultant working with companies in Tokyo — KipBill generates each invoice in the client's language and currency automatically.

Templates: 25 Industry-Specific Designs

Billin offers customizable invoice templates, but they follow a generic corporate style with limited variety.

KipBill offers 25 professionally designed templates tailored to specific industries:

• Photography — clean portfolio-style layout
• Construction — structured for progress billing and materials
• Legal — formatted for billable hours and retainers
• Restaurant — designed for catering and food service
• Dental, Veterinary, Fitness — each adapted to their billing patterns

Every template is available in all 12 languages and adapts automatically to your client's locale.

Quotes & Proposals

Both platforms support quotes and proposals. However:

• KipBill: Quotes are free for all users. Create unlimited quotes, send by email, and convert to invoice with one click.
• Billin: Quotes are restricted in the free plan. You need a paid subscription for professional use.

For a freelancer who sends 5-15 quotes a month, KipBill's free plan covers this entirely.

What Billin Does Better

Let's be fair. Billin has clear advantages in certain areas:

• VeriFactu already implemented — full compliance with Spain's electronic invoicing regulations
• TicketBAI — complete integration for businesses in the Basque Country and Navarra
• FACe — electronic invoicing to Spanish public administrations
• Kit Digital subsidized — free or heavily discounted for freelancers with 0-2 employees through a Spanish government program
• Extreme simplicity — clean, focused interface with no unnecessary complexity
• 180,000+ users — established platform with years of Spanish market experience
• Spanish-language support — dedicated customer service for the domestic market

If your business operates exclusively in Spain, you invoice only in euros to Spanish clients, and your absolute priority is VeriFactu and TicketBAI compliance right now — Billin is a proven choice.

VeriFactu Compliance

This matters for any business operating in Spain. Starting in 2027, all invoicing software must comply with VeriFactu regulations.

• Billin: Already VeriFactu compliant. This is one of its core strengths.
• KipBill: VeriFactu is our top priority on the roadmap, with implementation planned before the 2027 deadline. The technical architecture (SHA-256 hash chain, AEAT XML format, QR verification codes, automatic AEAT submission) is already designed.

Who Should Choose What

Choose Billin if:

• You only invoice in Spain, in Spanish, in euros
• You need VeriFactu and TicketBAI compliance today
• You want an ultra-simple tool with no advanced features
• You qualify for the Kit Digital subsidy to cover the cost
• You do not need AI features or international invoicing

Choose KipBill if:

• You want unlimited invoices and quotes on the free plan

• You are a freelancer, consultant, or small business owner working globally

The Bottom Line

Billin is a solid invoicing platform for Spanish freelancers who want simplicity and immediate tax compliance. Its 180,000 users and years of market experience speak for themselves.

But KipBill offers more for less. Unlimited free invoices, an AI assistant that no Spanish competitor matches, line-by-line receipt scanning, 25 professional templates, 12 languages, and 30+ currencies. And KipBill Pro (€5/month) costs less than half of Billin Pro (€12.5/month).

If you are looking for a Billin alternative that is more powerful, more international, and more affordable — KipBill is worth a try.
