Starting a low voltage business, part 10: assembling your prequalification package

How a low-voltage shop keeps one current prequalification package, matches insurance to each contract, and keeps project history, resumes, and financials consistent.

2026-10-11 · 14 min read

The previous post covered banking, bookkeeping, and financing. This one covers the moment those records are asked for: the prequalification package a general contractor, owner, or facility uses to decide whether the company is qualified to work for them.

Nearly every post in this series has pointed toward that request. The package is a collection of documents describing who the company is, what it has done, how it manages safety, who will perform the work, and whether it has the financial strength to complete the job.

This is where the earlier work shows up together. The licenses, insurance, EMR, safety programs, financial statements, bonding capacity, supplier relationships, certifications, and project history discussed throughout this series all become pages in the package. A company that built those pieces carefully can assemble a strong package quickly. A company that did not will discover the gaps at the worst possible time.

What this post covers

One base package. The documents nearly every request asks for, plus the extras a specific contractor adds.
The core sections. Company information, licenses, safety records, and insurance that matches the contract.
Money and history. Financials, a surety letter, and a project list that agrees with the books.
People and upkeep. Resumes and certifications, references, claims history, and a schedule for keeping the package current.

One base package, tailored as needed

Prequalification requirements vary depending on who is asking. A small general contractor may want a certificate of insurance and a few references. A large national builder, hospital system, or public agency may require a lengthy questionnaire, years of safety data, audited financial statements, and a surety letter before it will consider a subcontractor at all.

Rather than starting from scratch each time, build a base prequalification package that contains the information nearly everyone asks for, then add supporting documents as each request requires. Keep the base package current, organized, and ready to send. When a request arrives, a current package can go out within days. The speed and completeness of the response is itself a signal of how the company operates.

Many larger contractors manage prequalification through online platforms, where subcontractors enter their information and upload documents into a standard format. A well-organized base package makes those platforms easier to complete, since the answers and documents are already prepared.

What a prequalification package typically includes

Owner or management statement of commitment

Many packages ask for a signed statement from the owner or a senior manager affirming the company's commitment to its policies, particularly safety and quality. This is the same management commitment discussed in Part 7. It reads as a statement from the people who run the company. Reviewers see many of these, and specific language stands out.

Licenses and company certifications

Include copies of the licenses the company holds, as discussed in Part 3, along with the company's manufacturer partner status and certifications, as discussed in Part 8. License numbers, classifications, program levels, and expiration dates are current.

Safety documentation

Safety is often the largest section of a prequalification package, and it draws directly on Parts 6 and 7. Expect to provide:

The company safety manual and written programs, such as hazard communication, respiratory protection, silica, fall protection, and confined spaces
The company's EMR, supported by a rating worksheet or a letter from the insurer, or, for a new company, a letter confirming non-rated status, as discussed in Part 6
OSHA injury and illness logs, often for the last three years, along with injury rates calculated from them
Training records and the number of employees holding OSHA 10 and OSHA 30 cards
The name and qualifications of the person responsible for the company's safety program
In some cases, the employee handbook and drug and alcohol policy

As discussed in Part 7, underwriters and risk advisors read these documents, along with the project team, so the documents are specific to the company and consistent with each other.

Insurance and required endorsements

Providing a certificate of insurance is only the starting point. What the contractor needs to confirm is that the policies carry the coverages, limits, and endorsements its contract requires.

Most general contractors spell out their requirements in the subcontract or in a sample certificate, usually on an ACORD form, the standard certificate of insurance format used across the industry. The form shows exactly how the contractor expects the certificate to read, including required coverages, limits, and endorsements such as additional insured status, waiver of subrogation, and primary and non-contributory wording, as discussed in Part 6.

The process typically works like this:

Send the contractor's requirements to the insurance agent or broker. Ask them to compare the requirements against the current policies and identify any gaps.
Add any missing coverages or endorsements. The agent can then issue a certificate that matches the contractor's request.
Review the certificate before sending it. Confirm that the named certificate holder, additional insured wording, and limits match exactly what was requested. Contractors frequently reject certificates that are close but not exact.

Adding endorsements the company did not previously carry can increase the premium, and with it the monthly payments. That added cost belongs in the project price, the same as the other project-specific costs discussed in Part 7. Before assuming every project requires new endorsements, ask the broker whether blanket endorsements are available. A blanket additional insured endorsement, for example, can automatically extend coverage to any party the contract requires the company to add, which may cost less and require less administration than adding endorsements project by project.

Once a project is complete, project-specific endorsements do not stay on the policy indefinitely. Removing endorsements that are no longer required can reduce the premium. The contract terms come first. Many contracts require the contractor to remain an additional insured for a set period after the work is completed, commonly under completed operations coverage, because claims related to an installation can arise long after the project closes. Removing an endorsement before that period ends can put the company in breach of contract and leave it exposed.

Track these obligations carefully. For each project, record which endorsements were added, the date the work was completed, and how long each endorsement must remain in place, and set reminders to review them with the broker when the obligations end.

Include the broker's contact information in the package so contractors can request project-specific certificates directly.

Financial information and bonding

Larger contractors want assurance that a subcontractor can finance its work, pay its suppliers and employees, and complete the project without failing mid-job. Depending on the project, expect to provide:

A signed IRS Form W-9, dated within the last year. Nearly every contractor requires a current W-9 before it can set up a subcontractor for payment, and many reject forms that are more than a year old. The legal business name, federal tax identification number, and tax classification match IRS records exactly, since a mismatch can delay or block setup.
Financial statements, often reviewed or audited by a CPA for larger projects, as discussed in Part 9
A bank reference letter
Trade references from suppliers, such as the distributors discussed in Part 8
A letter from the surety stating bonding capacity, typically expressed as a single project limit and an aggregate limit, as discussed in Part 6

The surety letter is one of the most persuasive documents in the package. It shows that an independent financial institution has reviewed the company and is willing to guarantee its performance up to a stated amount.

Project experience

The project list shows reviewers what the company has actually done. For each project, typically include:

Project name and location
Customer or owner
General contractor or prime contractor, where applicable
Scope of work performed
Contract value
Completion date
A contact person who can verify the work

New companies have a narrower list, and the list can still be honest. The work does not need to have been contracted directly to the company to count. Work performed as a subcontractor to another low voltage contractor, or through a national integrator, is still work the company performed. What matters is accuracy. If the questionnaire asks who the prime contractor was, or what the company's role was on the project, answer accurately.

Company experience and key personnel experience are different things. Projects an owner managed or installed while working for a previous employer are part of that person's experience, not the new company's. That experience belongs in the resumes discussed below. Presented that way, a new company can show reviewers the depth of its team without misrepresenting its own history.

Project size must match the books

Reviewers frequently compare the projects a company lists against its financial statements. A company that claims to have completed several $500,000 projects while reporting $150,000 in annual revenue will raise immediate questions. The books show whether the company is capable of the size of work it claims, and of the size of work it is asking to be considered for.

This is one more reason the bookkeeping discussed in Part 9 matters. Clean, accurate financial statements that track revenue by project and service type make the project list credible. Inconsistent numbers undermine it.

Resumes for leadership and key technicians

Many prequalification requests, particularly for larger or more technical projects, ask for resumes of the people who will lead and perform the work. Not every package requires them, but they are common enough that they belong in the base package, ready to include when requested.

Maintain current resumes for:

Owners and company leadership
Project managers and estimators
Lead technicians and foremen
Key technicians, particularly those holding certifications on the systems the company installs

Each resume describes the person's current role, years of experience, and relevant projects, including experience gained with previous employers. It is accompanied by the certifications and qualifications that show the person can perform the work, such as:

Manufacturer certifications on the systems the company installs
OSHA 10 and OSHA 30 cards
State licenses held by individuals
NICET, BICSI, fiber, and other industry certifications
Aerial lift, fall protection, and other safety training
Any customer-specific requirements, such as healthcare training or security clearances

Resumes and certifications become especially valuable when tailored to a specific project. If a project specifies a particular access control or video platform, highlighting the technicians certified on that platform shows the reviewer that the company has the qualified people the specification requires. As discussed in Part 8, many manufacturer certifications are tied to the dealer account and to specific individuals, so reviewers may confirm that the certified people listed are actually employed by the company.

Keep titles and roles current as well. When a technician is promoted to lead, or a lead moves into project management, update the resume to reflect the new role and responsibilities. Reviewers often compare the resumes in a package against the project staffing plan and the key personnel listed elsewhere, and a resume that presents someone in an outdated role creates the same kind of inconsistency as a mismatched financial figure. A promotion is also a moment to note new supervisory responsibilities and any credentials, such as an OSHA 30 card, that came with the role.

Use a consistent, professional format for every resume, and keep copies of each certification organized by employee, alongside the training records and acknowledgments discussed in Part 7. Track expiration dates so that a lapsed certification is never submitted as current.

References

References confirm that the company does what it says it does. The strongest references are customers and other contractors the company has worked with directly. General contractors, building owners, facility managers, and electrical contractors who can speak to quality, reliability, and communication carry the most weight.

Some reviewers will accept other industry references, such as distributors, manufacturer representatives, or inspectors, but most prefer client references. Include industry references to supplement client references, rather than in place of them.

Before listing anyone, ask for their permission, confirm their current contact information, and let them know a call may be coming. A reference who is caught off guard, or whose phone number is out of date, does little good.

Claims and legal history

Many questionnaires ask whether the company has been involved in litigation, defaulted on a contract, had a bond claim, or been cited by OSHA. Answer these questions honestly and completely. A disclosed issue with a reasonable explanation is often acceptable. An undisclosed issue discovered by the reviewer usually is not.

Answer every question, accurately

A few principles apply to every prequalification package:

Complete every section. Incomplete packages are often set aside. If a question does not apply, such as an EMR for a non-rated company, say so and explain why rather than leaving it blank.
Be accurate and consistent. The same information often appears in several places, such as revenue in the financial statements, project values in the experience list, employee roles in the resumes and staffing plan, and employee counts in the safety section. Reviewers notice inconsistencies.
Do not misrepresent. Overstating experience, revenue, qualifications, or safety performance can result in disqualification, termination of a contract, and in some cases legal consequences, particularly on public projects. In a small industry, a reputation for exaggeration spreads quickly.
Present it professionally. A clean, organized, consistently formatted package reflects a company that will run a clean, organized project.

Keep the package current

A prequalification package is a living document. Build a schedule to update it as the underlying information changes:

W-9 at least once a year, and whenever the business name, address, tax identification number, or tax classification changes
Insurance certificates at every policy renewal
Project-specific endorsements when added, and again when the contractual obligation to maintain them ends
EMR each time a new rating is issued
Financial statements at the end of each fiscal year
Surety letter as bonding capacity changes
Licenses and company certifications as they renew
Resumes and individual certifications as employees join, leave, are promoted or change roles, earn new credentials, or renew existing ones
Safety programs at each annual review
Project list and references as projects are completed

Many general contractors require subcontractors to renew their prequalification annually. A package that is maintained throughout the year makes that renewal routine rather than a scramble.

Bringing it together

A prequalification package is where a company's preparation becomes visible. Every license obtained, every safety program written and acknowledged, every month of clean bookkeeping, every on-time payment to a supplier, every certification earned and promotion given within the team, and every satisfied customer becomes evidence that the company is ready for larger work.

Build a strong base package, keep it current, tailor it to each request, confirm that the insurance matches every contract's requirements, and keep it honest. General contractors are looking for evidence that a young company is organized, capable, safe, financially sound, properly insured, staffed with qualified people, and truthful about what it has done. A package that shows those things is what turns a new company into a trusted subcontractor.
