Extremely satisfied. It was a data crawling request with many complex conditions, but they understood the requirements accurately and kindly from the first consultation. The data was delivered in a clean, organized format and was highly usable.
Everyone else said it could not be done — they were the only one who pulled it off. I was in real trouble, but thanks to them it was resolved and I even got praised at work. Truly grateful.
They handled the requested data crawling accurately and quickly. The data was cleanly organized and ready to use right away. For difficult, complex crawling — this is the expert. I will definitely come back.
I handed over system design docs and requested development. Small errors came up along the way, but they listened to every single request and reflected it in the build. Satisfaction ×100.
So glad I found them — worth every won. Whatever the build, they deliver responsible, genuinely satisfying quality work. Thank you!!
Fast, communicative, and they shaped the data exactly the way I wanted. Watching how carefully they handle even a small job, I believe they are headed for much bigger things. Highly recommended.
It got complicated midway and took a bit longer, but I am satisfied! I want to entrust other work too!
Very kind, and the cost was reasonable. I will come back with my next request~
Perfect — honestly the kind of find you want to keep to yourself.
The results I wanted, on the schedule I wanted, in the format I wanted. Effortless.
They quickly produced exactly the information I wanted — perfectly usable for marketing. Thank you.
They already had many programs built, so I could get what existed right away. Finished my project fast thanks to them.
They understand exactly what you ask for and handle it fast. Thank you!
Asked for shopping-mall crawling and they finished it really fast. Thank you.
Thank you for the thorough, diligent work!

The three things that burn you in outsourcing — blocked by the system
Nothing outside the quote ever gets billed
Instead of promising "no extra charges", we publish the price of every possible extra up front. Nothing outside the quote can even be billed.
You never have to ask how it's going
If you have to ask how the work is going, the outsourcing has already failed. Milestone progress and deliverables are recorded on a dashboard you can check anytime with your request number and contact — no login.
We publish the reasoning behind the price
Quotes are computed from real signed-project data with an itemized breakdown, and our full rate table is public — compare us against any other vendor directly.
What the contract protects
Where outsourcing usually goes wrong, we close it off in the contract — not with promises.
- Ownership of what we build
- Copyright in the newly built work transfers to you once the contract amount is paid in full. General-purpose modules we owned beforehand stay with us, licensed to you without time limit for use in the deliverable.
- Balance only after acceptance
- The final payment is billed only after the agreed state passes your review.
- 30-day free defect fixes
- Defects are fixed free of charge for 30 days after delivery.
- Stop at any stage
- Nothing is charged before the kickoff payment. Stop after that and only the completion rate at that point is settled — the rest is refunded, and we never bill beyond what you already paid.

International FAQ
Do you work with international clients?
Yes. Freesi works with clients worldwide. All consultation happens asynchronously over live chat in English — no phone calls or video meetings required — so time zones are never a problem. Payment is handled via PayPal invoice in USD.
How do international payments work?
We send a PayPal invoice in USD after the quote is confirmed. The standard structure is a 30–40% deposit, with the balance due after you review the deliverables against agreed acceptance criteria. No payment module or account signup is required on our site.
What project sizes do you take from overseas clients?
Most international projects are in the $500–$5,000 range: web crawling and scraping, data pipelines, workflow automation, API integrations, and admin dashboards. Larger builds are possible after an initial project establishes mutual trust.
Who owns the source code and accounts?
You do. Full source code, infrastructure accounts, and API keys are delivered under your ownership — stated explicitly in the agreement. A 3-month free bug-fix warranty is included.
