Invoicing Your Clients Made Easy
With Abacus, you can create and send invoices effortlessly, whether you charge clients a fixed price or bill by the hour. Take control over your billing process with options for customization, multiple payment processor integrations, and profitability analytics.

Two Flexible Invoicing Options
1) Fixed Price – Send Before Project Begins
If your projects follow a clear scope and deliverables, Fixed Price invoicing is your best choice. Abacus allows you to set a price that reflects the full project cost and send an invoice before any work begins. Get paid upfront and ensure your budget is locked in from day one, helping your cash flow stay strong.
2) Hourly Billing – Based on Detailed Time Logs
For projects with varying scopes or ongoing work, Hourly Billing ensures you’re paid fairly for every minute worked. With Abacus, you can log and track time down to the second, automatically generating invoices based on your team’s hourly rates. No more manual calculations or estimating. Just accurate, transparent billing.
