How work gets done. Guaranteed.
With this variant, you get the worker's fixed-price bid for doing the work. Then you tell them that to make sure they are fully motivated and protected from the risk of under-estimation, you want them to raise their price by a multiplier. This has the advantages of being very simple and giving you the full protection of fixed-price. The disadvantage comes from the fact that neither you nor the worker know in advance exactly how much they under-estimated by. If you multiply their intial bid by just two, you may still not have raised it high enough (i.e. they may have under-estimated by five). Then you are stuck in the same situation as not doing anything. And if you raise it by five, and they only under-estimated by two, you've drastically overpaid. Paying five times the price of every bid is not something that every employer wants to do. Also, it does nothing to address the other issue: the fact that you can't reliably specify all the requirements in advance. So, if you would prefer a cheaper and more comprehensive variant, you should use the Hybrid Payment Variant, or Hybrid Payment Variant + Sherpa instead.
This variant is significantly cheaper than "Raise the Worker's Bid" because you only pay for the time the work actually takes. Additionally, it gives you the full protection of fixed-price when you need it; at the very beginning of the project. Then it switches you to hourly at the appropriate moment, so you can safely enjoy a significantly higher project completion rate and a 40% savings on the fee. You do it like this: Small trial project: Split off a small portion of your project into a trial project (using fixed-price). This lets you find the best worker for your project, and fully protect your money at the same time. Make sure to size the trial project appropriately (less than $200.00 in emerging economies and less than $700.00 in mature ones). That way it will have the best chance of being completed successfully. Most people don't know how to do this themselves. So if that describes you, simply require the bidding workers to do that for you. Click here to view the text we recommend you add to your project, to do this. This project is a larger sized project and can be difficult for you to estimate acccurately. If you are the winning bidder, I want you to finish it. To ensure you are fairly compensated on this project, I am following vWorker.com Best Practices and using the "Hybrid Payment Variant". To bid: Read about the "hybrid payment variant" at this link. Describe to me, exactly what portion of the entire project you'll do for the trial portion only. Place your fixed-price bid for doing just this trial (and not the entire project). Remember, your bid must be less than $200.00 if you are from an emerging economy and less than $700.00 if you are from a mature one. In your comment, tell me how much per hour you will charge me for the remainder of the project, if you are selected. Note: I may choose to opt-out of this second stage if I do not like your performance in the trial. So be sure to give me your best work at all times. Judge the trial results: If the worker completes it successfully, then go to the next step and hire them for the remainder of the project. If they didn't, the triple-point-guarantee gives you your money back. Rather than having to have waited until the end of the project to know they weren't good, you've figured it out in a very short time. You can now repost it. And you might consider using some other best practices in this document (such as "trial by fire" or "hiring a sherpa") to improve your worker interviewing process. Remainder of project: You award them a second project for the remainder of the work, using hourly. This slashes the potential for project failure by 5 times (from a troubling 25% to less than 5%)! And, using hourly also slashes the vWorker.com fee from 15% to 9%, saving you 40%! Note that you do need to follow the normal hourly procedures when you get to step #3. This include daily monitoring of your worker's AccuTimeCard™ and progress. If you don't have the time, ability or inclination to do this, then you should use the 3rd variant instead: Hybrid Payment Variant + Sherpa.

This option works the same as the Hybrid Payment Variant. However: rather than supervising the worker while they are working under hourly, you hire a 3rd-party expert to do it for you. A Tech Sherpa / Project Sherpa is a pre-screend pro, who does this for you and completely relieves you of daily supervision. A Sherpa charges $25-$90/hour (depending on where they live), and at the beginning you can expect they will take 30-45 minutes each day to do their review. Later, as the worker proves to be reliable, you can safely reduce this to monitoring to once every few days and cut your costs further. And as the worker continues to prove themselves, you can ultimately reduce it to just a once-a-week review. Even with this additional cost, it is cheaper than the "Raise the Worker's Bid" variant. And the larger the project, the more it will save, versus simply marking up their bid. To hire a Sherpa, chose that option when you post the project (under "Project Management".)
Do you have a good worker, whose only problem is that they can't seem to deliver on time? This is actually very typical in many industries. For example, the Standish Group found that there is a 75% chance that any software project will not be delivered in the time estimated, and other industries are similar. The good news is that there are ways to manage this. By completing the vWorker.com requirements wizard, you can greatly increase the chances of on-time delivery. But even this is not enough, because a competent worker can still estimate incorrectly despite this. To avoid an unpleasant surprise, we highly recommend that you take the delivery date that your worker estimated and calculate a realistic delivery date. That date will be either 5x or 2x longer than the worker estimated. You will not reveal this date to the worker, nor will you enter it into the site as an official date (since that would defeat the purpose). Instead, if the worker misses a milestone deadline and is still doing a good job, you will dole out some of the extra slack time that you have. And if they are not doing a good job, then you can still hold them accountable to the original date, and take the project into arbitration for a refund (via your money-back guarantee). This puts you in the driver seat.
