-
Does dvimpuestos send the SII directly to the AEAT or only generate the file?
Direct submission. dvimpuestos signs and submits invoices to the AEAT SII from Business Central, in real time, with no intermediaries. We have an enhanced SII version compared to the standard Business Central SII (public PDF comparison available).
-
Does dvimpuestos cover Verifactu?
No. Verifactu is covered by a separate Davisa extension, not included in dvimpuestos. If you need both AEAT tax filing and Verifactu-compliant invoicing, both products coexist without conflict in the same tenant.
-
How does the licence work? Is it per user?
Not per user, per tenant. One subscription covers the entire tenant and the customer assigns licences nominally to the companies they choose. You can start from 1 company (€80/month or €800/year, annual prepay); each additional company costs €70/month (€700/year) in the 2–10 tier, with progressive discounts in higher tiers.
-
Is there a free version or trial?
No. dvimpuestos does not offer a free trial or freemium version. We offer a guided demo so you can see the product running on Business Central before subscribing. Licences are always prepay.
-
What if I pay annually and cancel a company mid-period?
On annual prepay subscriptions the proportional amount is not refunded if you cancel before the end of the period. The company remains active until the last day of the paid period. Only Davisa can free up quota.
-
Which version of Business Central do I need?
dvimpuestos can run on cloud or on-premise (for the latter, please check with an advisor).
-
What if a company has no licence assigned and a user tries to use dvimpuestos?
dvimpuestos fields stay editable, but on save the system shows a notice with two options: "Assign licence" (if you have free quota) or "Buy more licences". On commercial documents we also offer "Clean and continue" to avoid blocking operations.
-
What size and type of company is it designed for?
Any Spanish company, regardless of size or sector. Where it qualifies most is in corporate groups with more than 10 entities, where multi-company tax filing consumes a lot of manual time. It covers the entire national scope including the Basque Country and the Canary Islands.
-
How does support work?
Support by email and phone with direct contact from Spain. No Bronze/Silver/Gold tiers: we work in transparent hourly blocks (10 h for €900). Updates for regulatory changes are included while the subscription is active.
-
What data does dvimpuestos send to Davisa servers?
For licence validation: AAD Tenant ID, email of the user assigning the licence, name and display name of the licensed company and the active companies counter. No accounting entries or VAT data is sent. Validation with 4 h cache and short token (24 h).

How does dvimpuestos differ from standard Business Central tax features?
Native BC Spain covers basic SII and little else. dvimpuestos automates AEAT forms from source (303, 347, 349, 390, 111, 115, 190, 180, 193, 232, 216, 241...), adds VAT prorata with recalculation, equivalence surcharge, IGIC Canary Islands and Navarra VAT, and improves the standard SII with more reliable submission.
