Finding jobs to bid on depends on your industry, but the core strategy is the same: get yourself listed on the right platforms, set up alerts, and respond fast. Whether you’re a freelancer pitching services online, a contractor chasing construction projects, or a business pursuing government or corporate contracts, there are dedicated channels built specifically for matching bidders with open work.
Freelance Marketplaces
If you sell a professional service like writing, design, development, marketing, or consulting, online freelance platforms are the fastest way to find open jobs and submit proposals. Each platform has a different fee structure and bidding style, so the right fit depends on how you prefer to work.
Upwork is the largest general freelance marketplace. Clients post jobs and freelancers submit proposals. Upwork charges freelancers up to 15% on a sliding scale, meaning the fee drops as you earn more with a single client. You can bid on hourly, fixed-price, or even full-time contract roles. The platform uses a “Connects” system where each proposal costs a small number of credits, which keeps low-effort spam bids down but means you should be selective about what you bid on.
Freelancer operates a more traditional bidding system. Clients post projects, freelancers submit competing bids with their price and timeline, and the client picks a winner. The service fee is 10% or $5, whichever is greater. It covers dozens of industries and tends to attract a high volume of smaller projects.
PeoplePerHour works similarly, with proposal-based bidding and a sliding fee scale from 3.5% to 20%, where smaller jobs carry higher percentage fees. Fiverr takes a different approach: instead of bidding on client posts, you create packaged service listings (“gigs”) at set prices, and clients come to you. Fiverr charges a flat 20% fee. If you prefer inbound work over outbound proposals, this model can work well once your profile gains traction.
For specialized fields, niche platforms often yield better-paying work. Toptal places vetted freelancers in software, design, and finance roles with no fees to the freelancer, but the screening process is highly selective. 99designs runs design contests where you submit work and win if the client picks yours, plus direct client invitations. Dribbble works as a portfolio site where designers attract inbound job opportunities for an $8 monthly Pro membership. Codeable connects WordPress developers with clients using a fair-pricing algorithm and charges freelancers nothing.
For local, in-person service work like furniture assembly, moving help, or handyman tasks, TaskRabbit charges a one-time $25 registration fee with no ongoing platform fees.
Government Contract Opportunities
Federal, state, and local governments post billions of dollars in contract opportunities every year, and most of them are open to any qualified business that registers properly. The central hub for federal contracts is SAM.gov, where agencies post pre-solicitation notices, active solicitations, award notices, and sole source notices. You can search contract opportunities on SAM.gov without creating an account, but registering lets you save searches, follow updates to specific opportunities, and join interested vendor lists.
Before you can bid on a federal contract, you need an active entity registration in SAM.gov. This involves getting a Unique Entity ID (replacing the old DUNS number), providing your business details, and completing several validation steps. The registration process can take a few weeks, so start well before you plan to submit your first bid.
If you’re a small business, several free resources can help you find and win government work. APEX Accelerators (formerly known as Procurement Technical Assistance Centers) offer one-on-one counseling to help businesses navigate the bidding process. The SBA’s SubNet lists subcontracting opportunities posted by prime contractors looking for small business partners. The Dynamic Small Business Search lets government buyers find your company based on your capabilities and certifications.
State and local governments typically maintain their own procurement portals separate from SAM.gov. Search your state’s procurement or purchasing department website to find open bids. Many municipalities also post requests for proposals on their own sites or through regional purchasing cooperatives.
Construction and Trade Projects
Contractors and subcontractors have dedicated platforms built around the unique workflow of construction bidding, where general contractors invite subs to bid on specific scopes of work within larger projects.
ConstructConnect is one of the largest construction project databases, tracking over 825,000 active projects across 382 metro areas. Their Project Intelligence Pro plan starts at $199 per month and gives you access to both public and private commercial project leads. The platform also includes bid management tools (SmartBid and iSqFt) that general contractors use to send digital invitations to bid, so having a profile there can generate inbound bid requests.
Other construction-specific platforms include The Blue Book Building & Construction Network, BuildingConnected (owned by Autodesk), and PlanHub. Each maintains databases of active projects and connects general contractors with subcontractors. Pricing varies, but most offer free basic profiles with paid tiers for full project access and lead notifications.
Beyond platforms, many general contractors maintain their own prequalified bidder lists. Reaching out to GCs directly, attending industry association meetings, and registering with plan rooms in your area can put you in front of opportunities that never hit the public platforms.
Corporate and Private Sector RFPs
Large companies regularly issue requests for proposals through their procurement departments, but these can be harder to find because there’s no single centralized portal. The most reliable approach is to go directly to the source: visit the websites of companies you want to work with and look for pages labeled “Suppliers,” “Vendor Registration,” “Procurement,” or “Small Business Programs.”
Many large prime contractors and corporations maintain in-house supplier directories. Registering in these portals puts your business on their radar when relevant contracts come up. Companies like Accenture Federal Services, AECOM, Amentum, and dozens of other large firms run dedicated small business and supplier registration portals. The upfront time investment of registering across multiple portals pays off when procurement teams search their directories for qualified vendors.
Supplier diversity programs are another entry point. Many large corporations have formal commitments to source a percentage of their spending from small, minority-owned, women-owned, veteran-owned, or disadvantaged businesses. If your company qualifies, getting the relevant certifications and registering with these programs can surface opportunities you wouldn’t find otherwise.
Setting Up a Bidding Pipeline
Finding jobs to bid on isn’t a one-time task. The most successful bidders build a repeatable system. Start by identifying three to five platforms or sources that match your industry and register on all of them. Complete your profiles thoroughly, since incomplete profiles get filtered out by both algorithms and human buyers.
Set up email alerts and saved searches on every platform you use. SAM.gov, ConstructConnect, and most freelance marketplaces let you create keyword-based alerts so new opportunities come to you rather than requiring daily manual searches. On freelance platforms, responding within the first few hours of a posting significantly increases your chances of getting noticed.
Track every bid you submit, including the platform, date, scope, your proposed price, and the outcome. Over time, this data reveals which platforms produce the best win rate, what price points are competitive, and where your time is best spent. A simple spreadsheet works fine for this.
Networking still matters, even in a digital bidding world. Many jobs never get posted publicly because the buyer already has a shortlist of trusted vendors. Attending trade shows, joining industry associations, and maintaining relationships with past clients keeps you on those shortlists. The visible bid marketplace is only part of the picture.
