CentraSales and payments
Quotes, invoices and work orders, with their receipts and what's still owed.
Your whole business, in one place
It's already built, so you start using it the same day. You use it with your team, from a computer or a phone, and it keeps working when the internet goes down.

What's in it
What it takes to run a business
Every part is connected to the others, so what you enter in one shows up wherever it should.
Customers
Each customer with what they've bought, what they've paid and their appointments.
Inventory
You know what you have and what's running out, and it goes down by itself with each sale.
Expenses and suppliers
What you pay, to whom and when, so you know what you really earn.
Calendar
Each day's appointments, with the reminder ready to send by WhatsApp.
Shifts and payroll
The week's schedule, and the payroll worked out from those same hours.
Your team, each with a user
Everyone signs in with their own and sees only the parts that are theirs.
Offline
If the signal drops you keep selling, and everything catches up when it's back.

You pay month by month and cancel whenever you want.

No surprises
What we put in writing
Your data is yours
You download all of it whenever you want, each table separately to open in Excel.
No contract
You cancel whenever you want, and what you already paid still counts until its date.
If a payment is late
Centra keeps working for seven days. After that it becomes read-only, and for three months you can see and download everything.
We tell you first
We write to you before the trial ends, when a payment doesn't arrive and before deleting anything.
Common questions
What everyone asks
Do I have to install anything?
No. Centra opens in the browser, on a computer or a phone. If you like, you install it with one tap to have it as one more app.
Does it really work offline?
Yes. If the signal drops you can keep making sales, payments and appointments, and everything catches up when it's back. What needs the internet, like changing settings, is done once it's back.
Does it issue Hacienda's electronic invoice?
Not yet. Centra's invoices are for keeping your sales and payments, and you keep issuing the electronic invoice with your usual invoicing tool.
How many people can use it?
As many as you need, at no extra cost. Each signs in with their own user and sees only what's theirs.
What happens to my data if I stop paying?
For three months it stays read-only, so you can see it and download it. If you pay in that time, everything comes back as you left it. After that it's deleted, and we email you before.
What if I need something Centra doesn't have?
Write to us. If it's something many businesses need, it may come to Centra. If it's just for yours, we build you a custom system.
