Avoiding Outsourced Development Scams: Five Warning Signs to Catch Before You Sign

Outright fraud — a vendor taking the money and vanishing — is rarer in software outsourcing than people expect. Where buyers actually lose money and time is a grey zone nobody would file a criminal complaint over: the price grows after work starts, "that was never in scope" surfaces at delivery, the handover arrives and the source code is not yours, and the person writing the code turns out not to be the party you contracted with.

What these have in common is not a bad vendor but a loose structure. Which is also the good news: structural risk almost always shows itself before the contract is signed. Below are five signals you can check before kickoff, each paired with what removes it. If even one of them appears, stop and ask for documents before going further.

You ask what something costs and get "let's schedule a consultation" instead of a number. That is not fraud by itself, but it means you cannot set a budget before work begins — and the later price gets settled, the more room there is for add-on charges and scope arguments afterward.

How to remove it: for a well-defined type of work, ask for a written range (low to high) before kickoff. If the vendor will not give one, ask why. If the answer is "not until requirements are fixed," then putting those requirements in writing is the actual first step. Vendors who open with price have less room to change the story later.

If "payments, notifications, and the admin panel are all included" was promised over messenger, with no contract and no scope document, the odds of hearing "that was not part of it" at completion are high.

How to remove it: keep the screen list and an explicit in-scope/out-of-scope split as an attached document, and structure payment in stages — kickoff, midpoint, and after acceptance. Splitting it that way means a single payment can never become the whole loss. A contract should state scope, timeline, warranty, and what happens if delivery slips. The clause-level detail is in outsourcing contract disputes.

You received the delivery, but the source code lives only on the vendor's server, and the accounts, domain, and API keys used to deploy it are all in the vendor's name. That is a structure that keeps you dependent on them for every future change.

How to remove it: write into the contract that the deliverable includes the complete source code, and that the accounts and keys required to operate the service transfer into the client's name. Whether that one line exists is the difference between a small handover and a rebuild costing millions of KRW (thousands of USD). If this is your first time outsourcing, read it alongside the first-time outsourcing checklist.

When nobody agreed on what has to be true for the work to count as complete, the completion notice arrives — and the invoice with it — regardless of whether the thing runs in your customers' environment. This is the classic gap where the demo is flawless and real usage breaks.

How to remove it: fix the acceptance criteria before work starts: tested against real data, concurrent use and exception cases verified, and an acceptance window (for example, a set number of days after handover). Tie the final payment to passing acceptance, and the definition of "done" belongs to the contract instead of to the vendor.

Two related warning signs: the party you contracted with is not the party writing the code, or you met on a freelance marketplace and they suggest "let's do this directly and save the fees." Subcontracting blurs who is accountable when something breaks, and leaving the platform removes escrow protection on your payment.

How to remove it: ask before signing who the actual developers are and whether any work is subcontracted, then put the answer in the contract. If you are using a marketplace such as Kmong (a major Korean freelance marketplace), keep payment inside the platform — the moment you move outside it, the reason you chose that platform is gone. The differences in protection between marketplaces are covered in five things to know about hiring developers on Kmong.

The five signals compress into three problems: price is opaque, scope and ownership are not in writing, and who builds it is unclear. So the direction that reduces the risk is equally clear: publish price up front, put scope and source code ownership in the contract, and make sure the builder is identifiable with no brokerage or subcontracting in between.

Freesi (freesi.net) addresses these structurally. We develop directly rather than broker, so there is no subcontracting (signal 5); prices are published per product so you can budget before kickoff (signal 1); and the contract states scope along with source code and account ownership (signals 2 and 3). No structure makes fraud impossible, so run these five checks wherever you hire. If you want to see types and prices first, they are on the fixed-price menu; how the work actually runs is on how it works.
