The short answer
Preparing for VeriFactu in 2027 is not buying a badge. It is knowing whether it applies, which date is yours (1 January or 1 July), which mode your SIF will use and whether the manufacturer hands you the responsible declaration. The 2026 dates are dead (RDL 15/2025).
The SME cleans data, picks a vendor and does not mix Facturae, SII or TicketBAI. The advisory firm splits the book by tax and by territory. Manufacturers have been obliged since 29 July 2025; you, if you are a user, have not.
Vacly Fiscal (€12.90/month VAT incl., 15-day trial) orders [taxes](/producto/fiscal/impuestos), [forms](/producto/fiscal/modelos-aeat) and the [calendar](/producto/fiscal/calendario-fiscal). It does not file with the AEAT, does not certify the program and does not remit records. Facturación is the inbox, not VeriFactu. This is not legal advice.
Why prepare this in 2026 if the date is 2027?
Because the software already has a manufacturer duty, and because changing system on 28 December is not a plan. The delay is not an invitation to do nothing.
- RDL 15/2025 moved the user dates to 2027. It did not move the manufacturers’ duty (29 July 2025). Calendar in [2027 dates](/blog/verifactu-2027-fechas-sociedades-autonomos).
- Companies: 1 January 2027. Self-employed under IRPF, income-attribution entities and non-residents with a PE: 1 July 2027.
- Changing SIF, migrating series and teaching whoever invoices takes months. It is not a New Year’s Eve plug-in.
- If you are in the SII, the Basque Country or Navarra, the work may be the other one: confirming that this regime does not apply. See [the differences](/blog/verifactu-sii-ticketbai-facturae).
- The short definition of the regime is in [what VeriFactu is](/blog/que-es-verifactu). Do not start the project from the logo.
SME checklist: five questions before you sign software
If you cannot answer these five, do not sign a contract that promises “you already comply”.
- Does it apply to me? Common territory, not SII, not foral. If you are unsure, stop and call the advisory firm. Do not hang the date on yourself by analogy.
- Which date is mine? Impuesto sobre Sociedades: 1 January 2027. IRPF or another obligor in art. 3.1: 1 July 2027.
- Which mode will we use? VERI*FACTU (remittance) or NO VERI*FACTU (local, signature, send on request). Both can comply. Detail in [requirements](/blog/requisitos-verifactu-sif-qr-hash).
- Where is the manufacturer’s responsible declaration? If there is only a logo, there is no document. The AEAT does not publish a list of programs.
- Who invoices today, and with which series? If issuance sits in three tools, the SIF does not “switch on”. You pick one and close the rest.
Advisory checklist: the book is not one mailing
A “VeriFactu 2027” email to the whole book mixes companies, the self-employed, SII and Basque clients. That produces useless meetings.
- Split by tax: corporation tax (January) and IRPF / rest of art. 3.1 (July). Do not send the same date to both groups.
- Split by channel and territory: SII, TicketBAI, Navarra. Those do not go on the 2027 list.
- Ask each client for the SIF name and the responsible declaration. If the client does not have it, the risk is theirs and the explanation is yours.
- Do not sell a badge. Do not say “Vacly already sends it”. Fiscal does not remit to the AEAT.
- Use the [calendar](/producto/fiscal/calendario-fiscal) for period VAT and forms. Do not turn it into the VeriFactu clock.
What does Vacly Fiscal do in this project (and what does it not)?
Fiscal makes the period readable. It does not replace the SIF, the advisory firm or the electronic office.
- [Taxes](/producto/fiscal/impuestos): VAT and other period figures from invoices and settlements. It is not a filing.
- [AEAT forms](/producto/fiscal/modelos-aeat): prepare and track the 303, the 111 and the rest. Official sending depends on certificates and on who files.
- [Calendar](/producto/fiscal/calendario-fiscal): VAT, withholding and form deadlines. Alerts to the company or the advisory firm.
- Price of the [Fiscal module](/producto/fiscal): €12.90/month VAT incl. 15-day trial. It does not file with the AEAT. It does not certify. It does not remit records.
- The law provides for sanctions if you fail the regime that does apply. We do not put amounts. Check the electronic office.
Does the invoice inbox get me ready for 2027?
No. Digitising issued and received invoices is inbox work. VeriFactu is a regime of the system that issues.
- Vacly Facturación reads PDF, image, XML or Facturae, classifies and exports. That is not a compliant SIF and not VERI*FACTU mode.
- Having period VAT in balance helps the advisory firm. It does not replace the chained hash or the RRSIF QR.
- Do not mix this screen with [what VeriFactu is](/blog/que-es-verifactu). They are different articles and different modules.
- If your issuing manufacturer is someone else, they still are. Fiscal is not sold as their responsible declaration.
- The useful 2026 work is clean series, tax IDs and totals. That does shorten the project. Do not sell it as compliance.
Who closes the decision: the advisory firm or a post?
The advisory firm and the AEAT electronic office. This text orders questions. It does not pick a mode, a manufacturer or an enrolment.
- This article is informational as of 19 August 2026. It is not legal advice and not an implementation plan.
- The official spelling and the Agency’s FAQs live on its electronic office. Read them before you sign.
- If the software salesperson and your adviser disagree, the written line wins, not the logo.
- The series: [what it is](/blog/que-es-verifactu), [dates](/blog/verifactu-2027-fechas-sociedades-autonomos), [requirements](/blog/requisitos-verifactu-sif-qr-hash), [SII / TicketBAI / Facturae](/blog/verifactu-sii-ticketbai-facturae).
- Once the SIF is chosen, keep using Fiscal for the period. RRSIF compliance is not a button on Taxes.
How Vacly Fiscal fits
Vacly Fiscal (€12.90/month VAT incl., 15-day trial) leaves the period ready to work: [taxes](/producto/fiscal/impuestos), [forms](/producto/fiscal/modelos-aeat) and the [calendar](/producto/fiscal/calendario-fiscal) in the [Fiscal module](/producto/fiscal). It helps the SME and the advisory firm see the flow. It does not file with the AEAT, does not certify the software and does not remit records. The SIF and the responsible declaration belong to the manufacturer. Line: advisory firm and electronic office.
