After delivering 100+ custom projects, we found that clients fall into the same traps repeatedly. Here are the 5 most common pitfalls to help you avoid them.
Pitfall 1: Starting with Vague Requirements
Many clients say "I need a management system" and developers start immediately. Halfway through, the client says "this is not what I wanted," leading to rework, extra costs, and disputes.
How to avoid: A professional developer will conduct thorough requirement research before quoting — clarifying feature lists, page prototypes, and interaction flows. Be cautious if they quote without asking questions.
Pitfall 2: Looking Only at Total Price
The same mini program: Vendor A quotes 30k, Vendor B quotes 80k. You pick the cheaper one, only to find everything costs extra halfway through, ending up spending 100k without finishing.
How to avoid: Ask for an itemized quote — how much each module costs, what pages are included, what is not included. The clearer the breakdown, the fewer disputes later.
Pitfall 3: Verbal-Only Communication
"I mentioned this feature before" — the most common phrase in project disputes. Verbal communication leaves no record, making it impossible to resolve issues.
How to avoid: All requirement changes and conclusions should be documented — confirmed in chat groups, saved in emails, recorded in project management tools. Reliable developers do this proactively.
Pitfall 4: Unclear Acceptance Criteria
When development is done, the client says "this is not what I wanted" and the developer says "I followed the requirements." Without written acceptance criteria, it is a mess.
How to avoid: The contract should include a requirements document as acceptance criteria, with clear standards for each feature. Interactive prototype confirmation is ideal.
Pitfall 5: Vendor Disappears After Delivery
Three months after launch, a bug appears. You call the developer and they are unreachable. Or you are told "this costs extra" and a small bug takes a week to fix.
How to avoid: Negotiate after-sales terms in the contract — free maintenance period, response time, whether bug fixes are charged, whether source code is provided. Writing these into the contract is 100x more reliable than verbal promises.
Conclusion
Custom development is not buying groceries — price is not the only criterion. Choosing a developer who takes time to understand your needs, writes details into contracts, and is reachable after delivery is more important than saving a few thousand yuan.
