I built Olivi: drop a CSV, get a ready-to-send invoice
Hey everyone,
I recently launched https://oliviapp.com - a tool that turns time logs into ready-to-send invoices.
If you're a freelancer or solo consultant who tracks hours in Toggl, Clockify, Harvest (or any other tracker) and then manually calculates totals and creates invoices - this is built for you.
Here's how the core feature works:
Drop a CSV from your time tracker - only date and duration columns are required, everything else is optional.
Olivi parses and groups entries by client and project automatically.
Get a ready invoice with pre-filled line items - descriptions, hours, rates, totals, all done.
Review and edit the invoice if needed.
Send it - email with PDF and time report attached, or grab a shareable link.
Olivi doesn't store your CSV file - it reads the data and that's it.
Once you've got your clients and projects set up, the whole thing takes about two minutes. Two minutes - and your client is already looking at your invoice.
You can see the full flow in the demo video on the https://oliviapp.com or here on https://www.producthunt.com/products/olivi.
Beyond the core import flow, Olivi also handles:
Payment method presets — configure once per client, auto-applied to every invoice
Tax rates (VAT) — per-client defaults, reverse charge support
Email composer — pick a template, customize the message, attach the PDF, send without leaving the app
Customizable email templates — edit tone and wording in Settings
Unbilled hours tracking — see what hasn't been invoiced yet, auto-pull unbilled time when creating new invoices.
Client, project & invoice management — everything in one place.
Fixed-price projects — track contract value vs. invoiced amount, remaining balance calculated automatically.
Dashboard alerts — overdue invoices and unbilled work, so nothing slips through the cracks.
I'd love for people to try it out and share their impressions here. There's a 14-day free trial, no credit card required.
Thanks for checking it out!
Yevgen
