Compare RENTALL vs. Renviq

RENTALL, a reliable mobile car rental and fleet management app, helps companies manage all aspects of their business. RENTALL is ideal for small, independent car rental businesses. It offers a variety of pre-configured and custom-made features that allow you to manage customers, rates, reservations and vehicles, as well as reports, maintenance, administration, and reports. Users can also use this solution to check-in and check-out on one screen. They can track all available vehicles, pending customer payments, and calculate all rental costs.

Renviq is a web-based rental operations platform for car, motorbike and boat fleets of roughly 1 to 100 vehicles. The engineering choices are the argument. Every booking stores three values per side — the true UTC instant, the location's naive local wall-clock time, and the IANA timezone — so a cross-timezone fleet sorts and bills correctly, and a retroactive timezone-rule change cannot rewrite what the contract said. Money is integer cents end to end, never floats. Four government filings come from the booking data already on hand, each with its real limits stated: Spain, VERI*FACTU — invoicing records chained with SHA-256 and sent to the AEAT web service once the operator installs their own certificate, with a tax QR on every invoice and credit note. No one certifies software for this — what exists is the producer's declaración responsable, readable inside the app. Spain, SES.HOSPEDAJES — renter and driver data to the Ministry of the Interior under RD 933/2021, sent under the operator's own credentials. The signed-contract message (AV) only; cancellations and the reservation message are not built. Italy, SdI — FatturaPA XML generated per invoice and downloaded. The operator transmits through their own accredited channel. Renviq does not transmit. Italy, Ca.R.G.O.S. — rental contracts to the Polizia di Stato. Cars only, because the record has no motorbike vehicle type. There is no test environment, so validation runs against production with the Check method, which records nothing. Deposits are held on a card the customer saves through the operator's own Stripe account, with the hold re-authorised every 7 days and partially captured at return. Nine locales, Arabic right-to-left on every page. Browser only. No native mobile app.
