Run client work
from the proposal to the paid invoice.
Keep clients, projects, and tasks in one place. Your team logs time on the work. You send proposals and quotes, turn billable hours into invoices, and see what is still unpaid, over budget, or running out of retainer hours.
No credit card required.
In Aruba, Bonaire, Curaçao, Saba, Sint Eustatius or Sint Maarten? Your island's tax is built in.
What you do in Zentract.
Clients, projects, and tasks
A project holds the budget, the tasks, and, when you bill that way, a retainer with included hours.
Time on the work
Start a timer from the dashboard or log time on the task. Each entry keeps the client, the project, and whether it is billable. The iOS and Android apps are for logging time away from the desk.
Proposals
Describe the scope, timeline, team, and budget, then share the proposal.
Quotes and invoices
Send a quote for the work. Draft an invoice from billable hours, or write one by hand. It stays a draft until you send it.
Reports
Time summary, project status, timesheet, and invoice report.
Financials
What you invoiced, what you collected, what is still owed, and how much of each retainer is used.
Local tax and payments for the Dutch Caribbean.
In Aruba, Curaçao, Sint Maarten, Bonaire, Saba or Sint Eustatius, Zentract puts your island's tax on every invoice and gets you paid in ways that work there.

OB, ABB, and BBO on invoices, quotes, and proposals, with the details each island requires and statements like “ABB verlegd” where the law asks for them. Included in every plan.

Getting paid on the islands
Clients pay XCG and AWG invoices with Sentoo, from their own banking app, straight from the invoice link. The money goes to your account, and the invoice is marked paid.
Invoicing in US dollars? Add your bank details and they print on every invoice; mark it paid when the transfer arrives.
Get paid with SentooFrom logged hours to a paid invoice.
A month of work for a hotel group in Curaçao: invoiced with OB, paid with Sentoo, and in Financials as soon as it clears. Wherever you are, the flow is the same; the tax and how clients pay follow your location.
The team tracks time on the client's tasks.
See retainers running low and projects heading over budget, before they cost you.
After the invoice is paid, Zentract keeps watching: the hours left on each retainer, and a written report on money at risk once there is enough history.
Hours used against what each retainer includes, with the ones running low called out.
