We answer the most common questions about Melosy so you can make the best decision for your business.
Melosy is a business management system (ERP) built especially for small and medium businesses. It lets you manage sales, expenses, inventory, customers, quotes and taxes from a single platform, with no technical knowledge required. It runs entirely in the cloud and can be accessed from any device.
No. Melosy works right in the browser. All you need is internet access and you can use it on your computer, tablet or phone. You can also install it as an app on your phone for direct access from the home screen, without taking up space like a traditional app. Instructions are inside the system under the "Download APP" tab.
You get 7 free days to try it with a registered card — we charge nothing for the first 7 days. Only on the 8th day do we make the first charge on the plan you chose (Monthly R$97,90 · Quarterly R$205,59 · Annual R$704,88). You can cancel from the dashboard at any time before the 8th day and pay nothing. No penalty, no contract.
We offer 3 options: Monthly (R$97,90/month — full flexibility), Quarterly (R$205,59 every 3 months, ≈ R$68,53/month with a 30% discount) and Annual (R$704,88 billed once a year, ≈ R$58,74/month with an 40% discount). All plans include the same features — you just choose the billing cycle that makes the most sense for your cash flow.
Yes. You cancel right from the subscription dashboard, with no phone calls or emails. If you cancel during the 7 free days, you pay nothing. If you cancel later, you keep using it until the end of the period already paid. No penalty, no fine print.
No. At Melosy we believe in total transparency. The price you see on the page is exactly what you will pay. We don't charge sign-up fees, cancellation penalties or commissions on sales or quotes. Your only investment is the plan's subscription.
Absolutely. We use Supabase (built on PostgreSQL) with data encryption in transit and at rest and automatic backups. Your financial data is never shared with third parties. Payments are processed by Stripe, and we never store your card details.
Yes. Melosy lets you create professional PDF quotes with your company logo, send them to customers via a direct link and track their status. When the customer accepts, you convert it into a sale with one click, without retyping everything.
Yes. The system automatically calculates the applicable taxes (ICMS, ISS, IPI, withholdings) on each sale, based on your company's configuration. That saves accounting time and reduces manual calculation errors. It also generates tax reports by period to simplify your filing.
Yes. Melosy issues NF-e (product sales), NFC-e (end consumer) and NFS-e (services) right from the system, with 100 invoices per month already included in your plan at no extra cost. Taxes are calculated automatically and your A1 digital certificate is set up inside the system itself. And Melosy is already ready for the Brazilian Tax Reform (IBS/CBS).
Yes, with no limit: you add as many users as you want, with no per-user cost. Each team member gets role-specific permissions — the salesperson sees sales, the finance person sees the cash flow — and you control exactly what each one can access.
Yes, with their own login and at no extra cost. The accountant accesses your company's invoices and reports right in the system, without you having to export and email files every month.
Yes. Melosy lets you connect several companies under the same login and switch between them with one click, at no extra cost. Ideal for those with more than one tax ID or who run different businesses.
