How it works

Four steps from overdue invoice to sent follow-up.

Add your invoices

Client, amount, due date — type them in or upload a CSV.

Chasa drafts the chase

Tone matches days overdue: friendly early, firmer later.

Tweak if you want

Edit the draft, or use Soften / Firm up / Shorten on paid plans.

Send from your inbox

Copy or open mailto — clients hear from you, not a bot.

Built for chasing payment — not collections theater

When the invoice is late and you still want the relationship.

Freelancers

Solo operators who hate rewriting the same reminder four times.

Small teams

A few people sharing chase volume without a collections stack.

One-off clients

Project work where one overdue invoice shouldn’t start a fight.

Price comparison

Chasa Solo is a flat $7/mo per workspace (Pro $17). Use the slider to estimate what the same team size costs on entry plans from each competitor.

Figures use published list prices (USD where available; Satago converted from GBP at ~$1.28). Competitors often include auto-send, SMS, or payment portals Chasa does not. Chasa never emails your clients — you send every draft yourself. See the full comparison →

FAQ

What is Chasa?

An AI invoice follow-up tool. Paste unpaid invoices and get payment reminder emails written in the right tone for how late each one is.

Do I need an account?

No — Free works without signup (5 AI drafts per month + templates). Sign in to upgrade to Solo ($7) or Pro ($17). For Enterprise (custom, billed yearly), email [email protected].

Does Chasa send emails for me?

No. You copy the draft into your own inbox (or open a mailto link). Clients hear from you, not from us.

Does Chasa connect to QuickBooks, FreshBooks, or Xero?

Yes for QuickBooks Online and Xero on Solo and up — native OAuth in Connector imports overdue invoices into aging. FreshBooks and Wave: create an API key and use our Zapier template, or export CSV and upload in the Tool (headers mapped automatically, Free too). Cloud storage (Dropbox, OneDrive, Box) PDF import is also Solo+.

How does the tone work?

Friendly under a week overdue, professional at 8–30 days, direct past 30 days. Same invoice, escalating tone — no template picking.
