How Contractors Start Jobs Before Receiving Payment

The job startup problem

Contractors win a job. The contract is signed. But the first payment may not arrive for weeks. Mobilization costs hit immediately—equipment transport, setup, initial materials, permits, labor to get started. You cannot begin work without spending first. This is one of the most common contractor cash flow problems and a main reason contractors look for contractor working capital or a contractor line of credit.

Why this happens in construction

Construction payment is typically tied to milestones. The first draw often arrives after initial work is complete. Mobilization—moving equipment, setting up the jobsite, ordering materials—happens before any payment. Clients pay for completed phases, not for getting started. The timing creates a gap even when the job is profitable. Understanding why the gap exists helps contractors plan and choose the right solution.

How contractors typically handle it

Contractors use several approaches. Some use reserves to fund mobilization. Others use contractor working capital to bridge the gap until the first draw. A contractor line of credit offers flexible access when starting multiple jobs throughout the year. Some contractors negotiate advance or progress payments with clients. The right approach depends on how often you start new jobs, the size of mobilization costs, and what funding options are available. For more detail, see when a contractor needs working capital to start a job.

What is contractor working capital?

Contractor working capital is funding used to cover day-to-day operating costs—payroll, materials, mobilization—when client payments are delayed. For job starts, it bridges the gap between mobilization and the first draw. It is designed for short-term timing gaps. When you have a signed contract and need to mobilize, working capital can fund the upfront costs. For more on how it works, see contractor working capital.

When does a line of credit fit?

A contractor line of credit fits when you start multiple jobs throughout the year. You draw when mobilization costs hit and repay when the first draw arrives. The revolving structure means you do not need to reapply each time. Contractors who regularly take on new projects often find a line of credit more practical than one-time advances. For line of credit use cases, see when contractors need a line of credit.

Funding options contractors sometimes use

Contractors have several options for starting jobs before payment. Contractor working capital can fund mobilization and initial materials. A contractor line of credit offers flexible access when starting multiple jobs. Construction equipment financing fits when the job requires new machinery. Construction business loans may fit larger capital needs. Matching the product to the use improves the fit. For equipment specifically, see how contractors afford equipment for new jobs.

What if the job requires materials before the first draw?

Materials often come before the first payment. Contractor working capital or a contractor line of credit can fund initial materials and mobilization together. For material timing, see how contractors buy materials before getting paid.

What if the job requires equipment?

If the job requires new or additional equipment, construction equipment financing is a separate need. Equipment financing is for machinery and vehicles. Working capital is for materials, mobilization, and operating costs. Some contractors use both—equipment financing for the machine and working capital for mobilization and materials. For more on equipment, see how contractors afford equipment for new jobs.

How to avoid mid-project cash shortages

Funding mobilization and initial materials reduces the risk of running short mid-project. A contractor line of credit in place before starting provides a backup when the unexpected happens. Understanding draw schedules and mapping them against expenses helps. For mid-project shortages, see what happens when a contractor runs out of cash mid-project.

How to choose the right option

Consider how often you start new jobs. One-time or occasional mobilization may fit contractor working capital. Recurring job starts may fit a contractor line of credit. If the job requires equipment, construction equipment financing is separate. For a full overview, see contractor cash flow problems.

Sizing funding for job starts

Understanding mobilization costs, initial material needs, and when the first draw will arrive helps you size the need. Contractor working capital or a contractor line of credit bridges the gap. For construction project cash flow management, see our dedicated guide. For preparation, see how to prepare for contractor financing approval.

Expansion into new markets

Entering a new geographic market may require mobilization, permits, and initial materials. Contractor working capital or a contractor line of credit can fund these costs before revenue from the new market arrives. For expansion funding, see contractor expansion opportunities and funding.

Mobilization cost breakdown: what to fund

Typical mobilization costs include equipment transport (moving excavators, loaders, trailers), jobsite setup (trailers, fencing, signage), initial materials (first order for the job), permits and fees, and first-week labor before any draw. A $200,000 job might require $25,000–$40,000 in mobilization. Mapping these costs against the first-draw timeline helps you size the funding need. This breakdown is specific to job starts—distinct from contractor mobilization costs, which covers the concept; this guide covers the how-to of funding it.

Frequently asked questions

Why do contractors need to spend money before the first payment?

Mobilization costs—equipment transport, setup, initial materials, permits—hit before the first draw. Labor and materials are needed to start work. Client payments typically arrive after milestones are completed.

What is contractor working capital?

Contractor working capital is funding used to cover day-to-day operating costs such as payroll, materials, and mobilization when client payments are delayed. It bridges the gap between when money goes out and when it comes in.

When does a line of credit make sense for job starts?

A line of credit makes sense when you start multiple jobs throughout the year. You draw when mobilization costs hit and repay when the first draw arrives. You do not need to apply each time.

What if the job requires equipment too?

Equipment financing is for machinery and vehicles. Working capital is for materials, mobilization, and operating costs. Some contractors use both—equipment financing for the machine and working capital for mobilization and materials.

How do contractors avoid running out of cash mid-project?

Funding mobilization and initial materials reduces the risk of running short mid-project. A line of credit in place before starting provides a backup when the unexpected happens. Understanding draw schedules helps.

What do lenders look at for job start funding?

Lenders typically review revenue history, time in business, bank activity, and the reason for funds. Having a signed contract can help. Some working capital products may move faster than traditional bank options.
