Light.vn System Programming (Individual features)

Per-Feature level support for Light.vn Systems

  • This is for individual function development for a single product
  • Once I’ve received your contact, I’ll present the “estimated time for developing the function”, the fee can be calculated by multiplying the hourly unit price.
  • I recommend you to decide the propeties of the functions, because the time for planning the propeties will be inclided in the estimated time.
  • When there’s a need for a change or fix, a meeting is necessary. I never execute without prior approval.
  • Please provide all necessary UI assets and other materials required for implementation. Implementation is possible using placeholder assets.

Min [h] Max [h] Unit price [USD/h] Submission time [Days]
1 5 18.00 3
6 20 20.00 4
21 - 24.00 (5-)
  1. The fees include any tax.
  2. A task under 1 hour is considered as 1 hour.
  3. Prices are calculated per range. (ex. The fee for 8 hour task is 18.00 x 5 + 20.00 x 3 = 150.00 USD)
  4. If you need an earlier completion date, you must base 50% of the base price as an express task fee.
  5. Submission time is calculated starting the day after the contract date.
  6. If the task is longer than 21 hours, submisision time = estimated time / 5 (rounded up to an integer)
    (ex. If the estimated time is 38 hours, 38 / 5 = 7.6 -> 8 days is the submission time)
