Turn Tracked Time Into Paid Invoices Automatically

Here is an uncomfortable number: most freelancers under-bill by 15-30%. Not because they overcharge or scare clients away — but because the hours they actually worked never make it onto an invoice.

The 20 minutes on a call. The "quick" revision on Friday night. The research rabbit hole that was genuinely billable. If it lives in your head or a notes app instead of a timer tied to a task, it evaporates. On a $60,000 book of work, a 20% leak is $12,000 a year you earned and never charged.

Why invoicing leaks happen

The leak is structural, not lazy. It comes from a gap between where work happens and where invoices are made:

Stage	Where it usually lives	The leak
Work	Your head / a to-do app	Tasks never logged as billable
Time	A stopwatch app or guesswork	Hours rounded down or forgotten
Rate	A spreadsheet	Wrong or outdated rate applied
Invoice	A separate invoicing tool	Manual re-entry — errors and omissions

Every hand-off between these tools is a place where minutes fall through the cracks.

The fix: one connected chain from task to payment

KAZI closes the gap by wiring four modules into a single flow — Projects Hub, Tasks, Time Tracking, and Invoicing — so a tracked minute cannot get lost on its way to an invoice.

1. Projects Hub gives every client a home

Create a project per client or engagement. Set the billing model — hourly, fixed, or milestone-based — and the hourly rate once. Everything logged against that project inherits the right rate automatically. No more "what did I charge them again?"

2. Tasks make the work concrete and billable

Break the project into tasks on a Kanban board: To Do → In Progress → Review → Done. Each task can be flagged billable or non-billable, so internal admin does not contaminate client invoices, and real work never gets miscategorised as "free."

3. Time Tracking captures the minutes at the source

Start a timer directly from any task with one click. No separate app, no switching context. The timer knows which project and task it belongs to, which client it bills to, and what rate applies. Forgot to start it? Add a manual entry after the fact. Every entry is attributed the moment it is created.

4. Invoicing turns entries into money — automatically

This is where the leak closes. When it is time to bill, KAZI pulls every unbilled time entry for the project and drafts an invoice — hours, descriptions, rates, and totals already filled in. You review, adjust if needed, and send. The client pays by card via Paystack, right from the invoice.

No re-typing. No cross-referencing a stopwatch app against a spreadsheet. No wondering whether Tuesday's call made it in.

A worked example

Say you tracked this week against the "Acme Rebrand" project:

Task	Time entry	Rate	Billable?
Logo concepts	4h 30m	$85/hr	Yes
Client call	45m	$85/hr	Yes
Internal file cleanup	30m	$85/hr	No
Revision round 1	2h 15m	$85/hr	Yes

When you generate the invoice, KAZI includes the three billable entries (7h 30m = $637.50) and automatically excludes the internal cleanup. Under the old spreadsheet method, that 45-minute call and the Friday revision are exactly the entries that would have vanished — roughly $255 recovered on one week of one project.

Recurring and milestone billing, handled

Not every client is hourly:

• Milestone billing ties invoices to project milestones. Deliver the milestone, trigger the invoice — and pair it with escrow so the client funds it up front.
• Recurring invoices auto-generate and send on a schedule for retainer clients, so predictable revenue arrives without you lifting a finger.

The outcome

Connecting time to invoicing does three measurable things:

• Recovers the 15-30% leak — billable minutes are captured at the source and flow straight to an invoice.
• Cuts invoicing time to minutes — no manual re-entry means an invoice is a review-and-send, not a data-entry chore.
• Speeds up cash flow — accurate invoices go out sooner and, paired with card payments, get paid faster.

You already did the work. This is simply about getting paid for all of it.

Get started

1. Start a free KAZI account.
2. Create a project, set the rate, and add a few tasks.
3. Track time straight from the tasks as you work.
4. Generate your first invoice from tracked time and send it in a click.
