01 · Shape the idea
Prove the work before the paperwork.
Write down what you are building, who will buy it, and what it takes to reach the first sale.
- Plan first
Write one plain sentence for who you serve, what they need, and why they would choose you.
- Plan first
Talk with likely customers. Record what they buy now, what frustrates them, and what would make them switch.
- Plan first
Choose the smallest useful product or service you can sell. List the direct cost and the price you plan to test.
- Plan first
Include the site, equipment, inventory, professional help, deposits, permits, insurance, payroll, and cash needed before revenue arrives.
- Plan first
Capture the offer, customers, sales path, operations, owners, startup costs, monthly costs, and a simple cash-flow forecast.
- Plan first
Mark the questions that need an attorney, accountant, banker, insurer, contractor, or business counselor. Do not guess through a high-cost decision.
02 · Choose the foundation
Decide the name, structure, and place.
These choices affect filings, taxes, liability, ownership, and which address appears on applications.
- Plan first
Compare a sole proprietorship, partnership, LLC, and corporation with qualified legal and tax help before filing.
- Plan first
Record ownership shares, contributions, decision rights, pay, exits, and what happens if an owner cannot continue.
- Plan first
Search the Illinois business database and check whether the name creates a trademark or online-brand conflict before buying signs or printing materials.
- Plan first
Identify every place where work, storage, sales, food preparation, or customer visits will happen. Home-based work can still trigger local or industry rules.
- Before opening
Ask Chester’s zoning and building staff whether the planned use, occupancy, signs, renovations, parking, and inspections fit the address.
- When it applies
Illinois Business Services handles formation or registration for corporations, not-for-profits, LLCs, and specified partnership types.
- When it applies
Illinois directs sole proprietorships and general partnerships using a name different from the owners’ full legal names to the local county clerk. Use Randolph County’s current form and confirm the filing and publication steps with the clerk.
03 · Set up IDs and taxes
Build the filing trail in the right order.
Form the entity first when applicable, then create the tax accounts the business actually needs.
- When it applies
The IRS application is free. The IRS says legal entities should be formed with the state before applying for an EIN.
- Before opening
Use IDOR’s current registration guidance to identify sales, withholding, income, excise, and other accounts that apply to the business.
- Before opening
IDOR directs new registrants to Form REG-1 and says applicable registration should be complete before purchases, sales, or hiring.
- Keep current
Record each federal, state, and local filing or payment after the agency assigns it. Add the return even when no tax is due if the account requires one.
- Before opening
Decide who records income, expenses, payroll, owner contributions, loans, assets, and sales tax. Keep source documents with each entry.
- When it applies
At this guide’s review date, FinCEN says entities created in the United States and their beneficial owners are exempt from BOI reporting. Foreign-formed entities registered to do business in a state can still fall under the rule. Verify the live FinCEN notice.
04 · Clear the permissions
Know what must approve the work.
Licenses and permits depend on the activity and the address. Ask before construction, ordering equipment, or announcing an opening date.
- Before opening
Chester’s business code requires a city license for businesses operating from a location inside city limits when the business is not otherwise licensed or regulated under the code. Ask the City Clerk which article, application, and fee apply.
- Before opening
Give city staff the address, planned use, floor plan, proposed work, signs, expected occupancy, and opening sequence. Get the required approvals before using the space.
- When it applies
Use the Illinois service directory, then verify each result on the issuing agency’s page. Requirements depend on the activity.
- When it applies
If the work is regulated, open the profession or industry page and follow its current application, entity, and renewal instructions.
- When it applies
Randolph County handles local environmental-health programs and inspects permanent, seasonal, and temporary food-service locations. Its page also routes cottage food, body art, water, and private-sewage questions.
- When it applies
Use Illinois EPA’s small-business roadmap if the operation can create emissions, wastewater, waste, or other pollution-control questions.
- Keep current
Keep submitted applications, approvals, inspection reports, certificates, account numbers, renewal dates, and the agency contact for every requirement.
05 · Set up the money
Separate the business and fund the first mile.
Make the cash trail legible before the first purchase or sale.
- Before opening
Ask the bank which formation, assumed-name, ownership, and tax-ID documents it needs. Route business income and expenses through the business account.
- Before opening
Document cash, check, invoice, card, online, refund, deposit, and chargeback procedures that fit the offer.
- Plan first
List cash on hand, committed funding, purchases, deposits, monthly costs, owner draws, debt payments, and the lowest safe cash balance.
- When it applies
Keep the business plan, owner information, formation records, licenses, quotes, projections, bank statements, and the exact use of funds ready for a lender or program application.
- When it applies
Filter official-source programs by project, audience, support type, availability, and Chester fit. Treat the listing as a lead, then verify the live program before applying.
- Before opening
Describe the owners, employees, property, vehicles, products, professional work, customer visits, contracts, and online operations. Record what is covered, excluded, and required by a lease or lender.
06 · Build the operating system
Make the first sale repeatable.
Write the simple routines that protect cash, customers, records, and the people doing the work.
- Before opening
Write how a customer finds you, asks for a quote, agrees, pays, receives the work, reports a problem, and buys again.
- Before opening
Put scope, price, payment timing, changes, cancellations, refunds, warranties, delivery, and ownership of work in writing. Use legal review where the risk justifies it.
- Before opening
Record lead times, minimum orders, payment terms, shipping, return rules, tax documents, and a backup for anything that can stop the business.
- Before opening
Use unique accounts, multifactor authentication, role-based access, tested backups, and a written rule for who can move money or change payment instructions.
- Keep current
Store formation documents, owner agreements, tax letters, permits, insurance, leases, loans, contracts, payroll records, and renewals in one controlled place.
- Before opening
Test the inquiry, quote, sale, payment, receipt, fulfillment, bookkeeping entry, tax treatment, and customer follow-up before the public opening.
07 · Prepare to hire
Do the employer setup before day one.
This section applies when the business will hire employees. Worker classification and payroll errors can be costly, so get qualified help where the answer is not clear.
- Before hiring
Do not choose employee or independent-contractor status for convenience. Review the actual working relationship with qualified tax or legal help.
- Before hiring
Illinois directs new employers to register electronically through MyTax Illinois or use its current employer-registration form and instructions.
- Before hiring
Configure federal and Illinois withholding, unemployment, wage reporting, pay statements, filing dates, and who reconciles payroll to the books.
- Before hiring
Review the Illinois Workers’ Compensation Commission handbook and arrange required coverage before work begins.
- Before hiring
Download the current form and employer instructions from USCIS. Build a secure process for completion, document review, retention, and reverification when required.
- Before hiring
Illinois says employers must report new employees to the state New Hire Directory within 20 days of the employee’s first day on payroll.
- Before hiring
Use the Illinois Department of Labor page to identify notices required for all employers and any additional notices triggered by the work or workforce.
- Before hiring
Prepare the offer, role, pay authorization, policies, emergency contact, safety training, access, timekeeping, supervision, and offboarding steps.
08 · Open and stay current
Launch with proof, then keep the file alive.
Opening day is a checkpoint. Compliance, cash, licenses, and the plan continue to change after it.
- Before opening
Check the license, zoning, occupancy, health, professional, tax, insurance, and employer items that apply. Keep proof where staff can find it.
- Before opening
List who opens, safety checks, cash controls, customer contacts, vendor contacts, issue escalation, closing, and the decision to pause if an approval is missing.
- Keep current
Compare bank balances, unpaid invoices, upcoming bills, payroll, taxes held, inventory commitments, and the forecast. Investigate differences while records are fresh.
- Keep current
Reconcile accounts, review profit and cash flow, save statements, review tax liabilities, and update the forecast with actual results.
- Keep current
Put each annual report, license renewal, tax return, insurance renewal, lease date, loan requirement, and inspection in a shared calendar with an owner and an earlier preparation date.
- Keep current
Before changing the name, owners, entity, address, location, activity, payroll, or regulated work, ask each affected agency and insurer what must be updated.
- Keep current
Compare sales, costs, cash, customer learning, capacity, risks, and the next funding need. Replace assumptions with evidence.
