The Agency Billing Tool That
Doesn't Break the Bank
Multiple clients. Multiple projects. Multiple rates. One tool that handles all of it for $1/member/month. Not $12. Not $15. One dollar.
Multi-client chaos is eating your margins
Agencies don't have a time tracking problem. They have a multi-everything problem. Multiple clients with different rates. Multiple projects running simultaneously. Multiple team members switching context all day. Multiple invoices due on different cycles.
Most agencies solve this with a patchwork: Toggl for time tracking, FreshBooks for invoicing, a spreadsheet for project profitability, and Slack messages asking "did you log your hours?" The patchwork costs $20-30 per person per month. And it still doesn't work because the data lives in three different tools that don't talk to each other.
Meanwhile, the invoices go out late. The project that was supposed to be profitable turns out to have burned twice the estimated hours. And nobody notices until the quarterly review because the data wasn't in one place.
One tool. Every client. Every project.
Miru was built for teams that bill by the hour. Time tracking, invoicing, expenses, payments, and reports — in one place. No patchwork.
Multi-project, multi-client
Your designers bounce between three clients before lunch. Your devs push to four repos by noon. Miru tracks time per project, per client, with different rates for each. No board setup. No column configuration. Just start the timer.
Team roles that make sense
Five roles: Owner, Admin, Employee, Book Keeper, and Client. Employees see their own time. Owners, admins, and bookkeepers see reports and invoices. Clients see only their invoices. Leave tracking is built in, so you don't need another HR tool.
Reports that answer real questions
Which client pays the most? Who is 60 days overdue? Five reports answer that: time entries, outstanding and overdue invoices, revenue by client, accounts aging, payments. Four analytics views add forecasts, team, client, and expense trends.
Invoicing from tracked hours
Select the client, pick the date range, and your team's tracked hours become invoice line items. Detailed enough that clients don't question the bill. Fast enough that invoices go out on time every cycle.
CLI for developer teams
Your engineers live in the terminal. Miru meets them there. `miru time create --project-id 42 --duration 120 --date 2026-09-10`. No browser tab. No app switch. Time tracking that fits into the workflow instead of interrupting it.
The math at scale
A 50-person agency on Miru pays $50/month. That's $600/year.
The same team on Harvest? $5,400/year. On Monday.com with time tracking? $11,400/year. On Toggl Premium? $9,600/year — and you still need a separate invoicing tool.
At agency scale that's $5,900–$10,200/year back in your budget.
Your billing tool shouldn't be your biggest expense
$1 per member per month, from the first member. A 50-person agency pays $50.
