Contasimple Reviews 2026: Honest Analysis of the Cheapest Software

An honest analysis of Contasimple in 2026, with the official rates verified on contasimple.com in June 2026. What it genuinely does well, where it falls short, what its Trustpilot reviews say and when each of the most relevant alternatives makes sense for your profile. Its prices exclude VAT, so you will also see the real annualized cost with the 21% added.

Contasimple has been on the Spanish market for more than fifteen years. Founded in 2009 and acquired by the French group Cegid in 2022, it serves over 20,000 freelancers (autónomos) and micro-businesses according to Cegid's official figure. Its positioning is clear: a correct, certified low-cost tool with a permanent free plan that few competitors offer. It is not a hand-holding tool or a proactive AI, it is a cheap tax cash register that complies with the law. For the right profile, that is exactly what you need.

What Contasimple is and who it is for

Contasimple is a cloud invoicing and basic accounting software designed for Spanish freelancers on a tight budget. The core proposition is to offer the bare minimum needed to comply with the AEAT at the lowest price on the market, with a genuine free plan that works as the entry hook.

The core features are:

• Basic invoicing with Verifactu generation (even on the free plan)
• Basic income and expense accounting
• Tax forms on the paid plans (303, 130, 115 and similar)
• Automatic bank reconciliation (paid plans)
• OCR and expense digitization modules, billed separately
• Mobile app included

Judging by the pattern of its reviews and the brand's own messaging, Contasimple fits the low-volume freelancer (1 to 20 invoices a month), with a very tight or zero budget, a low or medium technical profile and the need to comply with Verifactu without investing in software. For that specific profile it is a reasonable option. For growing freelancers, small businesses with a team or professionals who value service and support, there are options that fit better.

How much does Contasimple cost in 2026?

Contasimple has three plans. Important from the start: all the prices on its website exclude VAT (the page itself states "VAT not included"). Annual billing lowers the monthly fee. These are the official prices verified on contasimple.com in June 2026:

Prices excl. VAT (VAT not included) verified on contasimple.com in June 2026. The OCR and document digitization modules are contracted and billed separately (price not published).

What each plan includes

Básico (free for life). The entry hook and Contasimple's main differentiator. It includes basic invoicing and Verifactu generation, with a cap of 12 documents per year, 5 products, 1 user and 10 clients. For a freelancer who issues one invoice a month or has a very occasional secondary activity, it covers the essentials without paying anything. It is hard to beat if your only goal is to comply with the regulation without investing.

Profesional (€12.95/mo, €10.95 on annual billing). The plan Contasimple positions for freelancers with regular activity. It raises the cap to 500 documents per year and adds the tax forms (303, 130, 115 and similar), bank reconciliation and electronic invoicing. It is the natural step up when you issue more than one invoice a month and need to file your forms from the same tool.

Ultimate (€19.95/mo, €15.95 on annual billing). The complete plan: unlimited documents, products and batches. Built for micro-businesses with higher invoicing volume and more complex operations that outgrow the 500 documents of the Profesional.

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 both annual and monthly billing:

21% VAT included. Calculation based on the prices excl. VAT verified in June 2026. Annual billing saves versus monthly on both paid plans.

Here it pays to do a calculation almost no comparison does. Contasimple gives you the bare minimum to comply, but its model assumes you or your accountant do the rest of the tax work. If you do not yet have an accountant and end up hiring one, add €600 to €1,800 a year in fees (€50 to €150 a month depending on volume and region) to the software fee. For comparison, Facturaz costs €24/mo (€240/yr excl. VAT with two months free on annual billing, €290.40 incl. VAT) and its AI Coach replaces the accountant on most tasks. It is not the cheapest option on software alone, but it is once you add the real cost of having your taxes sorted.

Quick comparison with alternatives

Here is how Contasimple 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.

Contasimple's real strengths

What Contasimple does well, no sugar-coating.

• A genuine, permanent free plan. One of the few products on the Spanish cloud market with a free-for-life plan (not a trial) and Verifactu generation. For freelancers in the early stage with very low volume, it covers the essentials without investing.
• The absolute lowest price on the market. The Profesional at €12.95/mo (€10.95 on annual billing) is hard to beat if your priority is minimum cost. Billin Pro and Quipu Solution come out pricier for similar invoicing functionality.
• Verifactu from the free plan. It meets the integrity, traceability and tamper-proofing requirements of the anti-fraud system (Royal Decree 1007/2023, amended by RD 254/2025) across all its plans, with no complex setup.
• Fast invoicing. Reviews repeatedly mention how easy it is to issue an invoice in a few seconds. The interface, though dated, is optimized for simple cases.
• Functional bank reconciliation. On the paid plans it syncs with the main Spanish banks. Basic compared with premium products, but enough for simple accounts.
• Mobile app included. It lets you issue invoices and check your tax situation from your phone.
• More than fifteen years on the market. A consolidated product that knows Spanish regulation in detail, now backed by the Cegid group.

Contasimple's weaknesses

What you should be clear about before signing up.

• No proactive AI or hand-holding. Contasimple records what you do, but it does not anticipate tax problems or suggest optimizations. It is a pure operational tool, not a copilot that acts for you.
• OCR and digitization modules billed separately. Automatic expense capture is not included in the plans' base fee, it is contracted as an add-on module with a price that is not published. It pays to ask the real cost before signing up.
• Documents capped per plan. 12 per year on the free plan and 500 on the Profesional. If you issue more, you have to move up to the Ultimate. It pays to confirm what counts as a document, because invoices, expenses and other movements can add to the cap.
• A visually dated interface. Reviews describe the UI as less modern compared with newer cloud products like Quipu or Facturaz.
• Limited support. No real phone line on the entry plans. For urgent issues with Verifactu or tax forms, it pays to know which channel will handle you.
• Narrow functionality. No CRM, no projects, no inventory, no HR. It is pure budget tier. If you need any of those modules, look at Holded or an ERP.
• The price excl. VAT can mislead. €12.95/mo on the website is €15.67 with VAT. Always work out the real cost with the 21% before comparing plans across tools.

What users say

Contasimple has a 3.7/5 rating on Trustpilot. It is a modest score that reflects a polarized distribution: one part of users values the simplicity, the price and the fast invoicing, while another part reports a dated interface, slow support and just-enough functionality.

The pattern is consistent with its proposition. The positive reviews concentrate on low-volume freelancers with simple needs, exactly the profile it is designed for. The criticism comes from users who expected more service or more functionality than a low-cost product offers. It is not a flaw in Contasimple, it is its model: it does the minimum well and cheaply and it does not pretend to do more. If your profile matches that minimum, your experience will probably resemble the good reviews. If you expect support, fast service or smart automation, you will fall short.

Who Contasimple is ideal for

Contasimple fits especially well for very specific profiles:

• The early-stage freelancer with 1 to 5 invoices a month. The free Básico plan covers Verifactu without investing.
• The occasional freelancer or secondary activity that needs to comply with the AEAT without spending on software.
• A very tight budget, where the difference between €12.95/mo and €24/mo decides whether you can pay for the tool or not.
• The freelancer with a low technical profile who only needs invoicing plus minimal tax forms.
• Accounting firms that recommend software to small clients with no complex needs.
• Anyone who values complying with Verifactu at the lowest possible cost and accepts the lack of premium support and AI.

Who Contasimple is NOT ideal for

Contasimple is not the optimal option if your profile is away from its core proposition:

• Your business is growing and needs more features. The product does not scale beyond invoicing and basic accounting. Better to start with something that grows with you.
• You want an AI that anticipates problems. Contasimple has no AI Coach. To anticipate a VAT increase weeks ahead or spot forgotten deductions, Facturaz is the option in the freelancer segment in 2026.
• You want to reduce or eliminate dependence on an accountant. Contasimple is an operational product that assumes the underlying tax work is done by you or your accountant.
• You need CRM, inventory, HR or projects. They are not available at any price. Holded fits better.
• You operate in foral territories (Basque Country, Navarra). Contasimple has no full foral certification. Anfix is the best option for TicketBAI.
• You value fast support with a real phone line for critical situations with Verifactu or tax forms. Quipu offers better service on this point.

Alternatives by profile

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

Billin, for freelancers who only need to invoice

Billin (TeamSystem group), from €8/mo for the Básico, €15/mo for the Pro (€6.60 and €12.50 on annual billing, excl. VAT). Pure invoicing software with Verifactu compliance and a very clean interface. It is simpler than Contasimple and deliberately limited: it invoices well, but it does no accounting of its own and does not file tax forms. Note that Billin no longer has a permanent free plan, only a 30-day trial. Choose it over Contasimple if you only need to issue professional invoices quickly and nothing more and you accept using another tool for the forms.

Quipu, for service freelancers who value service

Quipu (TeamSystem group), Starter €17/mo, Solution €30/mo (€25 on annual billing, the one recommended for freelancers), Premium €59/mo (plus VAT). Invoicing, treasury and accounting software with a much more polished interface than Contasimple's, a (reactive) Genius AI assistant and a broad network of partner firms. Choose it over Contasimple if you value a modern interface and better service and you accept paying more: its Solution at €30/mo is more than double Contasimple's Profesional.

Facturaz, for freelancers and SMEs 0-10 who want to reduce accountant dependence

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 Contasimple: the two products serve opposite visions of what a freelancer needs.

Contasimple says: we give you the bare minimum to comply with the tax authority at the lowest price. You handle the rest, or your accountant does.

Facturaz says: your goal is not just to comply, it is for your taxes to run themselves. The AI Coach analyzes your invoicing, anticipates problems before they happen, prepares the forms and you approve with one click.

The difference is not in the monthly price, it is in what each platform does for you. Contasimple records what you do. Facturaz tells you what to do. The AI Coach spots a deduction you overlooked (equipment bought in March, a client lunch in April, training in May) and folds it into your next form. A single recovered deduction can offset the price gap for the whole year. And when it comes to filing the 303, Contasimple gives you the form to fill in, while Facturaz prepares it for you, with the input and deductible VAT already calculated from the invoices the AI read from your email.

On top of that, you do not need to know anything about accounting. You do not have to understand what a form 303 is, or which box the input VAT goes in, or how simplified direct estimation works. You invoice, Facturaz keeps the accounts, prepares the forms and files them with the tax authority after your confirmation. If you have a question, the AI chat answers 24/7 in plain language.

Honest about limitations: Facturaz is a new product (2025), without Contasimple's fifteen-year track record. It only covers common territory (national AEAT), without TicketBAI, so if you operate in the Basque Country, Anfix is still the right choice. It also has no inventory module, no CRM, no full ERP. And on software alone it is pricier than Contasimple. If your business is genuinely small and you only need to comply with Verifactu and nothing else, Contasimple is honestly the cheapest option. If you want to take the next step and start optimizing your taxes without depending on an accountant, Facturaz's AI Coach returns the price gap several times over.

Verdict: is Contasimple worth it?

Contasimple is not a bad choice. It is the right choice for a specific profile: the early-stage freelancer with an absolute minimal budget who only needs to comply with Verifactu without investing. For that case, the Básico plan or the Profesional at €12.95/mo are hard to beat.

The problem appears if your profile is not that one. For a growing freelancer or a professional who values service, the combination of limited support, dated interface and absence of proactive AI turns the initial saving into hours of manual work and the accountant's bill you take on separately. They do not compete for the same customer: Contasimple is a cheap tax cash register, Facturaz is a copilot that runs your taxes for you. They are two different ways of keeping a freelancer's books in 2026.
