The bill at the end of the meal is your income. Everything behind it is a cost. SolStack helps you manage it all.

Menus presents it

Places your menus in front of the guest before they arrive: photo, description, price, allergens, all in their own language. One source, multiple formats: paper, QR code, online and website. The shop window that makes them choose your dishes at your place.

Tables books it

Turns "that looks good" into a reserved table and a confirmed cover. Easy online booking with email confirmations before the date, plus automated confirm-or-cancel reminders that cut no-shows dramatically. Handles staff-entered walk-ins and phone bookings the same way. For large parties you can block out rooms or the whole restaurant so other guests do not get a bad experience.

Staff runs the team

No more filing cabinets of cuadrantes (rotas), fichajes and staff paperwork. The legal Registro de Jornada is kept automatically from every clock in and out; contratos and Convenio categories, vacaciones and ausencias, onboarding and a printable Recibo de pago, all handled online.

Social advertises it

Stop the time-consuming hassle of managing multiple social media accounts. Upload your photos and words once and leave the posting to us: scheduled to YouTube, Facebook, Instagram, X, Bluesky and Threads on your timetable.

Events elevates it

Promote that tasting menu, Christmas Day or New Year party, an outdoor BBQ or a themed night. Create the social and print advert with online posting and repeat scheduling up to the event date. Put a booking link and QR code on every advert to maximise income.

Financials proves it

Shows which dishes, menus and events actually make money, which only look busy, and what each one really costs. No hidden costs: rent, IBI, utility bills, staff wages, and the biggest grey area of all, what suppliers actually charge for ingredients, captured straight from scanned delivery notes. Focus on the winners and drop the losers.

Custom your business app

Got a revenue stream we do not cover yet? Rooms above the restaurant? A wine club? A cookery school? Beach sunbeds? We build it as a custom app on the same platform: one login, the same guests, feeding the same financials. Customised to your business requirements.

Billing that fits how you actually trade, not a flat fee whether you use it or not.
No setup fee. No minimum contract. Leave whenever you like.

One platform

Apps that already
know about each other.

Not a stack of subscriptions you glue together. One login, one staff list, one set of opening hours, one master menu and revenue that arrives in your P&L by itself. All the apps share a common platform; developed together to work together in multiple languages.

Every app references the same business data. The same guest list, the same menus and the same opening hours. A single version of the truth.
