Payment amounts match total × percentage

乙方 bank account details are included

Common Pitfalls to Avoid

Vague acceptance criteria — "功能正常" is not enough. Specify: "可发布租房帖子并完整展示全部字段，房型筛选可用"
No penalty cap — Always cap delay penalties (standard: 15% of contract value)
Missing change order process — If scope changes, reference supplementary agreement mechanism
No fapiao/invoice terms — Consider adding if client needs formal tax invoices
Unclear IP during development — IP belongs to developer until full payment, then transfers
Missing source code delivery — Specify that source code + docs are delivered upon payment
No force majeure — Consider adding for larger contracts
Maintenance period ambiguity — Clearly state start date (delivery acceptance) and duration
