Open a Business Bank Account and Keep Useful Job Books
Use a separate business account and a job ID to connect estimates, purchases, labor, invoices and payments. Useful books explain both job results and cash timing; they do not depend on a universal tax-reserve percentage or a member bookkeeping provider.

Before you start
- Business legal identity and the selected bank's current document requirements.
- A list of estimates, invoices, purchases and owner transactions.
- Professional confirmation of applicable payroll and tax obligations.
What you will finish with
- A bank-document and fee-comparison record.
- A job-cost ledger linked to receipts, approved changes and payment.
- A reconciled cash calendar showing operating and seasonal commitments.
Source note: sources below were checked as of October 11, 2026. Product revisions, local rules and your written quotes control the actual job. Unknown costs stay blank.
Separate business transactions
Give business income and spending a dedicated record from the first transaction. Keep transaction evidence even when an owner initially pays a business expense personally.
Bank documentation
Ask the bank which documents it requires for your actual entity and owners. Use its secure process for identifiers and formation records; do not put those documents into the public worksheet.
Compare actual fees, payment timing and account terms
Compare the actual account fee schedule, deposit/payment services, settlement timing and withdrawal terms. Record dates and assumptions for when money is available rather than assuming a card payment is immediate cash.
Owner contributions and draws
Label owner contributions and draws separately from job income and operating expenses. Ask your bookkeeper how to record them for the entity's actual accounting and tax treatment.
Set up categories that explain a job
Choose categories that let you reconstruct a job. Keep accounting treatment consistent with your bookkeeper while using practical operating records for estimating.
Materials, labor, equipment, travel and disposal
Record delivered materials, paid hours, equipment use, travel, cleanup and disposal against the job ID. Record owner labor in the estimating comparison without inventing a payroll treatment.
Overhead versus direct costs
A direct cost belongs to a documented job; overhead supports the business more broadly. State the chosen allocation method when overhead enters a bid, and avoid charging the same cost twice.
Invoice and receipt records
Connect invoice, receipt, vendor, quantity, date and payment evidence. Retain supporting documents in an organized, secure system following IRS and professional guidance.
Track each estimate through payment
Keep a job's chain of evidence together from estimate to payment. When the customer changes the work, change the scope record before the invoice loses its explanation.
Job ID and scope changes
Assign a stable job ID and version the estimate, signed scope and written changes. Record who authorized an addition, its price and its effect on schedule or closure.
Deposits where permitted and retainage
Verify whether deposits are permitted and how they must be recorded. Track retainage, money the customer withholds under agreed terms, separately with the contract and release condition.
Accounts receivable and supplier bills
Accounts receivable are unpaid customer amounts; supplier bills are amounts the business owes. Put both due dates on the cash calendar and connect each entry to its source document.
Reconcile the account and review jobs
Reconciliation compares your records with the bank so missing, duplicated or mistimed transactions can be found. Do it consistently and investigate differences before treating the balance as spendable cash.
Bank reconciliation
Compare cleared transactions with the ledger, record outstanding payments and deposits, and resolve each difference. Preserve the statement and the review note with access controls.
Estimated versus actual material/labor
Compare estimated and actual material, paid hours, preparation, travel and rework. Record whether a difference came from a scope change, missed quantity, operating problem or price change.
Margin versus cash in the account
A job's accounting margin and the money currently in the account answer different questions. Customer payment delays, deposits, loan principal and upcoming bills affect cash timing even when the job result is positive.
Plan payroll, taxes and the off-season
Prepare a cash calendar from confirmed obligations and dates. Seasonal planning starts with the actual cost of keeping the business operating during slower months.
Amounts and dates confirmed with professionals
Confirm payroll, tax, coverage and filing amounts and dates with appropriate professionals and authorities. No generic tax-reserve percentage or withholding calculation is prescribed here.
Working-capital timing
Place supplier payments, payroll, overhead, debt payments and expected customer receipts on the same calendar. Test slower collection and weather delays with clearly labeled entered assumptions.
Secure document retention
Keep secure records and usable backups; decide who may access payroll, tax and bank documents. Ask your adviser about retention for each actual record type rather than using one universal period.
Keep payroll records and review unpaid invoices
Unpaid invoices and payroll records need regular attention even when the crew is busy. The books should show both the document trail and the next action.
Approved hours, pay statements, tax filings and reconciliations
Retain approved time, pay information, filings, payment evidence and reconciliations in the appropriate secure payroll system. Verify federal and state requirements through current official sources and qualified help.
Receivables aging and payment follow-up
Group receivables by their actual due dates, note disputes and follow-up contacts, and use the collections module when professional escalation or legal deadline review is needed.
Live member tax help is separate from paid payroll/bookkeeping work
No qualifying member payroll or bookkeeping provider is documented for this guide. The optional Business Tax Hotline addresses tax questions only for its included plans; it does not process payroll or keep the books.
Read the cash and break-even calculations
Cash closing balance = opening cash + money received − money paid during the period. Enter actual dates; an unpaid invoice does not belong in money received.
For a chosen comparable unit of work, contribution per unit = entered selling price − variable cost per unit. Break-even units = fixed costs for the chosen period ÷ contribution per unit. If contribution is zero or negative, this model cannot show a usable positive break-even quantity; review the scope, price and costs.
Keep the unit and time period consistent and show the included cost basis. This model does not forecast demand, establish a tax provision or declare the owner's take-home pay.
Record and reconcile one completed job
Assemble the job documents
Collect the estimate, approved scope/changes, invoices, receipts, time records and completion evidence under one job ID.
Record costs and invoices
Enter dated quantities and payments in consistent categories, keeping owner transactions and overhead treatment visible.
Match money movements
Connect customer receipts and supplier payments to bank transactions and note items still outstanding.
Reconcile differences
Compare the ledger and bank statement, investigate missing or duplicate entries and save the reconciliation record.
Review actuals and cash
Explain differences from the estimate, update receivables and carry upcoming obligations into the cash calendar.

Frequently asked questions
Why should I separate business and personal banking?
It creates a clearer business transaction record and makes reconciliation and document handoff easier. Record owner contributions and draws separately and follow the entity's actual accounting treatment.
Which costs belong to a job?
Track documented materials, paid labor, job equipment, travel, preparation, cleanup and disposal consistently. Record overhead separately and declare how it is allocated in estimates.
How can a profitable job cause a cash shortage?
Materials, payroll and bills can be due before the customer pays; loan principal and other cash movements also affect the balance. Use the cash calendar alongside the job-cost result.
How do I record deposits and change orders?
Keep the contract, permitted deposit terms, written change authorization, revised price and payment evidence under the same job ID. Ask your bookkeeper how each entry is recognized.
When should I review estimates against actuals?
Review a completed job when its material, time and bill records are available, and update missing items when they arrive. Reuse the explained differences in later estimates.
What records should I keep for my bookkeeper?
Keep bank statements, sales/invoice records, receipts, vendor bills, payroll records, ownership transactions and approved changes in an organized secure system. Confirm retention and tax treatment with your adviser.
How do I budget through the off-season?
List actual recurring and seasonal payments alongside expected receipts and test a slower-payment or delayed-work scenario. No supported universal runway target or reserve percentage is published here.
