Duevero
Duevero is simple invoicing and profit-tracking software for freelancers, consultants, contractors, and solo service businesses. Create estimates and invoices, manage clients, track expenses, monitor invoiced, collected, spent, and profit totals, follow up on overdue work, and accept eligible invoice payments through your own connected Square account.
The free Basic plan includes up to 10 active clients, 10 invoices per month, 5 estimates per month, one workspace, expense tracking, and raw CSV exports.
Duevero Pro is $12/month and adds unlimited clients and invoices, 2 workspaces, recurring invoice templates, reports, time tracking, formatted and accountant-ready exports, an overdue and reminders workspace, and branded invoices with your logo.
Duevero is designed to be lighter and easier to use than a full accounting suite, giving independent service businesses one straightforward place to manage the client-money workflow from estimate to invoice to payment and profit.
