GoFeed vs Contasimple: invoicing the work without running the books

What each one covers

The comparison works once you accept that both issue invoices and that the resemblance stops there. Contasimple looks towards taxes: it computes the statutory forms, sorts the expenses and prepares the quarter. Invoicing in a content agency looks towards the engagement: where the amount came from, who approved it and what was delivered in exchange.

Three of those rows go to Contasimple with no argument possible, and they are not buried at the end of the article for a reason: they are what decides the choice for a lot of readers. If what you want is a program that handles your taxes and signs your documents, the answer is in the left hand column and this text can save you time by saying so in the first third.

What Contasimple costs today

The ladder has three rungs and charges per account, not per user. What climbs with the tier is not accounting power but volume: how many documents you can issue in a year, how many products you keep in the catalogue, and which kind of certificate the signature accepts.

The figures for the two paid plans exclude VAT, as their own page warns, and annual billing comes out 20 % below quarterly. Storage is the other variable worth checking before deciding: the free tier carries 5 MB of disk, Profesional 100 MB and Ultimate 1 GB, which for anyone who attaches the PDF of every expense is not a minor detail.

The free tier is real, and that is rare

It is worth separating a free plan from a trial with an expiry date, because half the sector calls the second one the first. Contasimple calls its own tier free for life, and what sits behind it is real invoicing: twelve documents a year, five products in the catalogue, one user and two invoice templates. It is not much volume, but it is enough for a sole trader who issues one invoice a month and would rather not pay for that.

There is a nuance written into their own pricing table that deserves reading before you settle on that tier. On the free level, the VAT and IRPF form calculation and the digital signature come as a 30 day trial rather than permanently. Basic invoicing stays with you forever and the two tax features expire, which is a reasonable way to split it and at the same time the reason most people end up moving a rung up.

There is nothing equivalent on the other side. The trial runs fourteen days, asks for a card it does not charge until day 15, and carries one brand, one connected social account and a ceiling of ten posts that does not renew. When it ends the workspace is not deleted: it drops to a floor where social accounts go to zero and the data is still there the day you come back. That is a floor so an expired workspace does not vanish, not a tier anyone can sign up to, and calling it anything else would be a lie.

Verifactu labelled tier by tier

Contasimple does something uncommon and genuinely useful: instead of a blanket label, it says which mode each plan supports. Basico is shown as Verifactu ready; Profesional and Ultimate are shown as ready for both Verifactu and non Verifactu, meaning they can also operate under the alternative regime while the transition period lasts.

That distinction is not decoration. The regulation allows two ways of complying, and choosing wrongly at the start is paid for later, because the user has to pick between Verifactu mode, with automatic filing to the Spanish tax agency, and exempt mode, from the very first invoice and even during the free trial. A vendor showing you that choice in the pricing table rather than burying it in the documentation is a point in its favour.

Its Verifactu page also puts a specific date on it: since 29 July 2025 it declares compliance with the regulation and describes the system as fully adapted and certified, with guaranteed traceability, unalterable invoices and automatic filing to the tax authority. Comparing that wording with what other Spanish programs write is more informative than it sounds, and the exercise is done in Quipu, Holded and Contasimple side by side.

Which part of the regulation exists on the other side

Royal Decree 1007/2023 is three requirements, not one. An invoicing record for every invoice issued. A chain of hashes linking each record to the previous one, so that altering an old invoice breaks the whole chain. And, only in Verifactu mode, submitting that record to the Spanish tax agency with the QR code printed on the document.

Of those three, what is built in GoFeed is the second: every issued invoice is computed over a frozen field order and linked to the previous one. The QR and the filing are not there, and this comparison will not hint otherwise. It is the only piece of the product badged as pending, and if you need those two things today you need a Spanish invoicing package that carries them, whether that is Contasimple or another.

Series, VAT regimes and the chain that starts at the brief

What does sit around the hash chain is the part that decides whether an invoice works in Spain. Your own numbering series, so white labelled invoices do not mix with yours and each series keeps its own consecutive count. Eight VAT regimes with their exemption grounds, which is what you need when your client list holds a Portuguese company, a Spanish sole trader and a reverse charge transaction. And IRPF withholding, the income tax a Spanish invoice may retain, applied on the document even though the forms that declare it come from elsewhere.

The real difference, though, is not the invoice but what precedes it. The brief takes fifteen field types and can also be generated from a PDF the client uploads. The quote is assembled from the service catalogue, so the line items already carry their description and their price. The contract inherits those lines. And the invoice comes out of that, so the amount the client sees is the one they approved weeks earlier and nobody has transcribed anything.

Each document is shared through a tokenised public link, with no account asked of anyone, and those pages are not indexed. The quote also records when it was opened. All of it lives in agency workspaces, the ones with clients that have a fiscal identity of their own; a creator or in house workspace has no commercial documents because there is no third party to invoice. The detail is on the quotes and invoices page.

What Contasimple does better

Four specific things, and none of them is filler.

Electronic signature. Contasimple signs documents, quotes included, and distinguishes per plan which certificate type it accepts: on Profesional only the program certificate, on Ultimate both kinds. On the other side there is no electronic signature of any kind, the contract is signed outside the product and no signature provider is integrated.

The permanent free tier with real invoicing, already explained, which is the most honest front door of the four Spanish tools this site compares. A freelancer can issue a compliant invoice from it without a card on file and without a countdown running in the corner of the screen, and that is a genuinely different proposition from a fortnight of full access.

The per tier Verifactu labelling, with the alternative mode declared, which is information that saves a support call and a badly made decision on the first invoice. None of the other programs compared here takes that detail down to plan level.

And taxes. Calculation of the IRPF forms, rental and supplier withholding, VAT forms and intra community transactions. That is accounting, and it does not exist in a content tool. The sensible reading, again, is not replacement: it is deciding which program closes your quarter and which one issues the paper the client reads. What the content side costs is on the pricing page, and the contrast with the other Spanish reference program is in the Quipu comparison.
