For small and mid-sized businesses
Business management software, built for your trade.
A small service business doesn't need an ERP. It needs the calendar, the clients, the register and the stock in one place — with a version that matches what you actually do.
- Appointments
- Medical Records
- Cash Control
A small business's problem isn't missing software, it's having five
The typical small business isn't running without systems, it's running too many. A calendar on someone's phone, clients in a spreadsheet, invoicing in another program, stock in a notebook, and the month's summary in the owner's head. Every piece works and none of them talk to each other.
The cost doesn't show up as an invoice, it shows up as time: entering the same customer three times, not knowing whether someone paid without opening two apps, closing the month by cross-referencing spreadsheets on a Sunday. That's administrative work nobody hired for and everybody pays for.
Business management software solves that by integration, not by feature count. The value isn't that it has a calendar — it's that the appointment, the client, the payment and the report are one piece of data seen from different angles.
Generic doesn't work, and custom-built doesn't either
Generic management systems fail the same way: to serve everyone they speak to no one. A veterinary clinic needs clinical records, a workshop needs history per vehicle, a language academy needs a tuition grid. None of those are solved by "customers" and "products".
The usual answer is a custom build, which solves the problem and creates two more: it costs what it costs, it depends on whoever wrote it, and every change is another quote.
Siimplo sits in between: one platform with eight versions, one per trade. You share the base — clients, sales, cash, reports — and use the modules your activity needs, already built and maintained. No in-house development, and no system designed for something else.
Start free and grow without migrating
The other reason small businesses postpone this decision is risk: choosing wrong means entering data for months and then having to get it out. That's why the free plan isn't a gesture, it's the way to try without committing.
On the Free plan you run scheduling, clients and sales, and you get your own website with online booking. No card and no expiry date: if you never pay, you keep using it.
When the business needs more — automatic reminders, full stock, multiple locations — you switch on a paid plan over the same account. No migration, no export, nothing re-entered.

Appointments
The day's bookings with the service, the vet assigned and confirmation status, in list or calendar view.
Ryo, the AI assistant
Ask in your own words and it walks you through Siimplo step by step; it also reads your real schedule and drafts the appointment for you to confirm.
Waiting Room
Triage your walk-ins: waiting, called or seen, tagged urgent through low, with arrival times on every row.
Live Waiting Room
Today's appointments on one side, who has arrived on the other — call the next one in with a single click.
Follow-ups
Who is due back and when — post-visit checks and recalls queued automatically instead of living in someone's head.
Reports
Revenue, expenses and net profit for any date range, with a trend chart, a category breakdown and a downloadable report.
Pet Owners
Every owner with contact details and remaining credits, invitable to your booking site in one click.
Medical Records
A profile for every patient — species, breed, age — carrying the clinical history that follows the animal across visits.
Credit Packages
Prepaid plans per client with credits used, credits left and validity — plus a filter for the ones about to expire.
Sales & Invoices
Every invoice in one ledger — paid, partially paid, pending or draft — with the register built into the same screen.
Cash Control
Open and close the register with opening and expected balances, income, expenses and every movement tagged by payment method.
Payables & Receivables
What you owe and what you're owed, aged past 30, 60 and 90 days, with the overdue count on every row.
Inventory & Stock
Medication, medicated food and disposables with SKUs, stock bars, cost and sale price, and low-stock alerts.

Track what you've ordered from whom, when it was placed and when it's due — with late deliveries flagged.
Suppliers
Your vendor book with tax ID, contact person, ordering email and internal supplier code.
Team & Permissions
Your staff roster with roles, last activity and access toggles, plus a permissions tab as the business grows.
Messages
Client conversations kept in the record instead of scattered across personal phones, with unread counts and archiving.
Reminders
Follow-up tasks tied to a client with due dates, so “I'll call them back” becomes something you can actually track.

Multi-store
Run every store from one account on the top plan, each with its own team, stock and register.
