Billin Reviews 2026: Real Prices and Honest Analysis

An honest analysis of Billin in 2026, now rebranded as TeamSystem Facturas Billin after joining the TeamSystem group (the same one behind Quipu and Factusol). You will see all three plans with their official prices, the real cost with VAT, what it genuinely does well, where it falls short on purpose and when each of three alternatives makes sense for your profile.

Billin was born with a deliberately simple proposition: do one thing very well, invoice fast from your phone with no learning curve. It is a polished invoicing tool, pleasant to use and well rated by its segment. If you are here, you are probably considering signing up, already using it and wondering whether something better exists, or evaluating software for your clients. Here is the analysis, no filter.

What is Billin and who is it for?

Billin is pure cloud invoicing software, designed for Spanish freelancers (autónomos) who value simplicity and mobility. The core proposition is to do one thing exceptionally well: issue professional invoices with Verifactu compliance from any device. Since joining TeamSystem, the brand presents itself as TeamSystem Facturas Billin, though plenty of people still just call it Billin.

The core features are:

• Fast invoicing with professional templates
• Electronic invoicing with Verifactu, Facturae and TicketBAI included
• Automatic expense reading from a photo or supplier email
• Basic stock management at no extra cost
• Mobile app for iOS and Android
• Data export for your accounting firm

For freelancers with low volume, a low technical profile and an external accountant who already handles the tax forms, Billin is hard to beat. For anyone who needs more (tax forms filed without extra software, real accounting, an AI that anticipates problems), there are more complete options. We break it down below.

How much does Billin cost in 2026?

Billin has three plans, all billable monthly or annually. With annual billing the per-month price drops by around 17%. Important: the old Billin brand had a permanent free plan, but the current TeamSystem website no longer offers it. Today there is only a 30-day free trial. These are the official prices excluding VAT, verified in June 2026:

Prices excl. VAT, verified in June 2026. The Básico plan allows 1 user and a maximum of 10 products. Pro raises that to 3 users. Ilimitado opens clients, users and products with no cap. There is no permanent free plan: only a 30-day trial. Trustpilot 3.7/5 across 89 reviews (74% five-star, 19% one-star).

What each plan includes

Básico (€6.60/mo on annual billing). The entry plan: Verifactu-compliant invoicing, 1 user, 0 to 5 clients, up to 10 products and 5 documents a month. For freelancers who barely issue invoices and only need to comply with the anti-fraud law.

Pro (€12.50/mo on annual billing). The most balanced plan for an active freelancer. It raises to 3 users, 6 to 50 clients and 50 documents a month. This is where expense reading and the daily invoicing routine come fully into play.

Ilimitado (€20/mo on annual billing). Clients, users and products with no cap, with 250 documents a month. Built for freelancers with high volume or small structures that invoice heavily.

One point in Billin's favor: electronic invoicing (Verifactu, Facturae and TicketBAI), stock management and the mobile app come included in every plan, with no separate paid modules. That is transparent and uncommon in its price range.

The real annualized cost with VAT

The website prices exclude VAT. To know what you really pay, you have to add the 21% and project it over a full year. This is the real annual cost of each plan, on annual billing:

21% VAT included. On monthly billing each plan costs around 17% more per month.

Here comes the calculation almost nobody does. Billin is an invoicing tool, not a complete tax platform. To file your forms 303, 130 or 349 you need to add accounting by another route: your external accountant or extra software. The real cost for a freelancer who wants the full package is not just Billin's fee, but that fee plus whatever you pay for the tax side. For comparison, Facturaz costs €24/mo (€240/yr excl. VAT with 2 months free on annual billing, €290.40 incl. VAT) and includes invoicing, accounting and form filing in one place, with an AI Coach that replaces the accountant on most tasks.

Quick comparison with alternatives

Here is how Billin compares with three relevant alternatives for freelancers. To keep it fair, for each tool we use the plan recommended for a freelancer, on annual billing.

Prices verified in June 2026 on the official websites. Each tool has a different ideal profile. Billin wins on mobile simplicity. Facturaz wins on the full package with an AI Coach for freelancers without an accountant.

Billin's real strengths

What Billin does well, no spin, based on user reviews and the product's own proposition.

• Fast invoicing from your phone. The promise of invoicing in a few seconds is real. Speed and simplicity are what positive reviews mention most.
• Minimalist interface with no learning curve. Designed for freelancers with a low technical profile. Anyone can start using it in minutes.
• Full electronic invoicing included. Verifactu, Facturae and TicketBAI in every plan, with no separate paid modules.
• Stock management and mobile app at no extra cost. Uncommon in its price range.
• Automatic expense reading. It processes receipts from a photo or a forwarded supplier email, which cuts manual work.
• No mandatory lock-in. You can cancel with no penalty beyond the period you contracted.
• TeamSystem backing. Same group as Quipu and Factusol, with operational stability.

Billin's weaknesses

What the honest analysis and the reviews point to as limits. Most are intentional, but it pays to be clear about them before signing up.

• No tax form filing. Billin exports data for your accounting firm, but filing forms 303, 130 or 349 is not done by the software itself. You need an external accountant or another tool.
• No real accounting. It is an invoicing tool, not an accounting program. To keep full books, you depend on another solution.
• No more permanent free plan. The old brand had one. The current TeamSystem website only offers a 30-day trial.
• No proactive AI. It handles the basics very well, but it does not anticipate VAT increases, does not catch forgotten deductions and does not suggest optimizations on its own.
• Falls short as the business grows. For freelancers who will need more functionality, it pays to start with a product that scales better.
• Public reviews with one point to watch. Trustpilot 3.7/5 across 89 reviews: 74% five-star, but 19% one-star. Overall satisfaction is good, though the tail of negative reviews is not negligible. Read the most recent ones before deciding.

What users say

Billin holds a 3.7/5 rating on Trustpilot across 89 reviews. The pattern is clear: most users rate the invoicing speed and the simple interface very highly, while the criticism concentrates on functional limits (no real accounting, no tax forms) and the occasional support incident. That 19% of one-star ratings, against 74% five-star, paints a product loved by its segment but capable of frustrating anyone who expected something more complete.

In short: if you are a freelancer who only needs to invoice fast and already has an accountant for the rest, the positive reviews reflect your likely experience. If you expect a complete tax package, check the points where Billin is deliberately simple first.

Who Billin is ideal for

Billin fits especially well for profiles where its proposition hits the mark:

• Freelancers who just need to issue invoices fast from the phone and nothing more.
• Creative freelancers or service consultants who invoice a few times a month with recurring clients.
• Freelancers on a tight budget who already have an external accountant for the tax forms and the accounting.
• Those who value simplicity over extensive functionality and have a low technical profile.
• Freelancers who need TicketBAI in Basque foral territory, since it comes included.

Who Billin is NOT ideal for

Billin is not the optimal choice if your profile is away from its core proposition:

• You want to file forms 303, 130 or 349 with no extra software. Billin does not file them. At that point, there are more integrated options.
• You need real accounting, not just invoicing.
• You want a proactive AI that anticipates tax problems weeks before they happen. Billin is a simple operational product, with no AI Coach.
• Your goal is to reduce or eliminate dependence on an accountant. Billin does not replace one. For tax autonomy with AI, Facturaz is built for that.
• Your business is growing and will need more functionality. Billin does not scale into a complete package.

Alternatives by profile

Three options that cover the profiles where Billin is not the optimal choice.

Contasimple, for the absolute minimum budget

Contasimple, free for life (with a document cap) or from €10.95/mo on the Profesional plan on annual billing. Owned by Cegid, it includes basic accounting and the tax forms Billin does not file, at a very low price. Choose it over Billin if your absolute priority is cost and you need to file forms with no extra software. In exchange, reviews after the Cegid acquisition point to a drop in support quality. Read the ones from the last 12 months before signing up.

Quipu, for service freelancers who want a full package from the same group

Quipu, from €17/mo (€30/mo for the Solution plan, €25 on annual billing). Like Billin, it is owned by TeamSystem, but with different positioning: Billin is simple and mobile-first, Quipu is a full package with accounting, treasury and tax forms. It has a (reactive) Genius AI assistant and a network of more than 1,000 partner firms. Choose it over Billin if you want invoicing, accounting and forms in a single piece of software and your volume justifies the higher price.

Facturaz, for freelancers and SMEs 0-10 who want proactive AI without an accountant

Facturaz, free until your first invoice and €24/mo after that. An AI CFO for freelancers and businesses with up to 10 employees. Here is the underlying contrast with Billin: the two products serve opposite visions of what a freelancer needs.

Billin says: we do one thing very well, invoice fast. For everything else, use your accountant or connect other software.

Facturaz says: we give you the full package. Invoicing, accounting, forms 303, 130, 111, 115, 349, 347 and 100, plus an AI Coach that anticipates problems before they happen. You approve with one click.

The difference is not just price, it is paradigm. Billin records what you do. Facturaz analyzes your business: it anticipates a VAT increase two weeks ahead, catches a deduction you were about to overlook and prepares the forms for you to simply confirm. And you do not need to know what a form 303 is or which box the input VAT goes in: the AI Coach does it and the AI chat answers your questions 24/7 in plain language.

The full-package calculation makes the contrast clear:

Honest about limitations: Facturaz is a new product (2025), without the long track record of more veteran brands. It has no human mentor like a traditional accounting firm, nor a full ERP module with CRM or advanced inventory like Holded. If you need that, Facturaz is not your option. For the 95% of freelancers and SMEs 0-10 who just want to invoice, comply and optimize without complications, it is.

Verdict: is Billin worth what it costs?

Billin is not a bad choice. It is an excellent choice for a specific profile: a freelancer who already has an accountant (or is happy to get one) and only needs a simple, fast invoicing tool. For that case, the Pro plan with electronic invoicing included is very competitive. The critical point is that its model takes for granted that the tax side is covered by someone else. If that premise matches your situation, Billin wins. If your goal is the opposite, to reduce dependence on an accountant and have everything in one place, Facturaz goes that way with an AI Coach that replaces the accountant on most tasks. They do not compete for the same customer, but for two different ways of running a freelancer's finances in 2026.
