How do you outsource bookkeeping as a residential contractor

Get your deposit handling right first. Then hand over invoicing, change order billing, allowance tracking, payables, and reconciliation to a bookkeeper. You keep approvals, signatures, and pricing. Your CPA keeps the tax work.

Start with deposits because that is where residential books usually break. A $40000 deposit is not revenue on the day it lands. Treat it as income and your profit and loss lies to you for the next four months.

Wishup is a virtual assistant company in the United States. Its bookkeepers handle job costing and client billing for residential contractors inside the software the business already runs.

Why residential books work differently

You get paid by homeowners, not by general contractors. That changes almost everything about your books.

A subcontractor bills a GC on a pay application schedule and waits for retainage. You take a deposit from a family before the first demo day. You bill against milestones you wrote yourself. You chase a personal check, not an accounts payable department.

Four things follow from that:

• Deposits are a liability. Money sits in your account that you have not earned. It belongs in a customer deposit account, not in revenue.
• Change orders happen mid-job, verbally. The homeowner asks for a different tile on Tuesday. Somebody has to turn that into a signed document and a line on the next invoice.
• Allowances move. You budgeted $6000 for fixtures. They picked $9400 worth. That $3400 overage has to reach the invoice.
• Your client is emotional about money. A GC disputes an invoice with a spreadsheet. A homeowner disputes it in your inbox at 11pm. Clean, itemized billing prevents most of those conversations.

Step 1: Set up the deposit account

Before you outsource anything, create a customer deposit liability account in your accounting software.

Every deposit lands there. As you complete work and invoice against it, money moves from that account into revenue.

This takes ten minutes to set up. Skip it and three things go wrong. Your profit looks huge in month one and terrible in month three. You pay tax on money you have not earned. You cannot tell how much of your bank balance is actually yours.

Your bookkeeper will run this once it exists. They cannot create the structure from your bank feed.

Step 2: Decide your billing method per job

Residential work runs on two models, and they need different bookkeeping.

Fixed price

You quoted $180000 for the kitchen and primary bath. You bill against a milestone schedule. Your margin is whatever is left after costs. Your books need tight job costing so you know, mid-job, whether you are on track.

Cost plus

You bill actual costs plus a fee or percentage. Your books need every receipt coded to the job and ready to share with the homeowner. Sloppy coding here is not an internal problem. It is a trust problem with a client who reads every line.

Most residential contractors run both, depending on the job. Tell your bookkeeper which is which on day one.

Step 3: Write down your change order rule

Change orders cause more unpaid money in residential work than anything else.

The pattern is familiar. Homeowner asks for something extra. You say yes on site. Work gets done. Nobody writes it up. Six weeks later you invoice for it and the conversation goes badly.

Your bookkeeper cannot bill what they never see. Agree the rule before they start:

• Who writes the change order, and within how many days
• Where the signed copy gets stored
• Whether it goes on the next invoice or a separate one
• What happens when work was done without one

That last question is the one that matters. Your bookkeeper should flag unbilled change work, not quietly absorb it.

Step 4: Clean up before handover

Do not hand someone a backlog and expect a useful report in week one.

A few months behind, scope a bookkeeping cleanup. A year or more behind, catch-up bookkeeping is a separate job with its own price.

For residential contractors, cleanup usually surfaces the same four problems. Deposits recorded as income. Credit card spend never coded to a job. Change orders done but never billed. Personal and business spend mixed on one card.

Step 5: Hand over the right information

Gather this before day one:

• Accounting, bank, credit card, and payroll access
• Current job list with contract values and billing method
• Signed contracts with payment schedules
• Allowance schedules per job
• All signed change orders
• Outstanding customer deposits by job
• Subcontractor list with W-9s and certificates of insurance
• Supplier accounts

The contracts matter most. Your payment schedule, your allowance amounts, and your change order terms all live there. A bookkeeper working without them is guessing at when to invoice.

Step 6: Split the work three ways

Your bookkeeper handles:

• Deposits recorded to the liability account and drawn down correctly
• Invoices on each contract’s milestone schedule
• Change orders billed once signed
• Allowance overages and credits on the invoice
• Receipts and material costs coded to the job
• Subcontractor invoices and accounts payable
• Weekly bank reconciliation
• Payment follow-up with homeowners
• 1099 and W-9 tracking for subs
• Monthly job cost reports and gross profit per job

You handle:

• Payment approvals
• Pricing, bids, and allowance amounts
• Change order conversations with the homeowner
• Anything that becomes a dispute

Your CPA handles:

• Tax returns and planning
• Revenue recognition method
• Entity and owner compensation decisions

A bookkeeper does not file taxes, issue audited financials, or act as a CFO or controller.

Step 7: Choose where to outsource residential bookkeeping

Freelance bookkeeper

A freelance bookkeeper costs least. You do the vetting and the managing. Few have handled customer deposits or cost plus billing, and you will not find out until a quarter in.

Local accounting firm

A local accounting firm is strong on tax and knows your state’s contractor rules. Weekly transaction work usually sits below what their hourly rate justifies.

Managed service

A managed service gives you a dedicated bookkeeper, with vetting, training, and replacement handled by the provider. Wishup’s bookkeepers onboard in sixty minutes, against one to two weeks at most agencies, and come from the top 0.1 percent of applicants.

Step 8: Ask these five questions

A standard bookkeeping interview misses what you need. These do not:

• A homeowner pays a $40000 deposit. Where does it go, and when does it become revenue?
• We allowed $6000 for fixtures. They spent $9400. How does that reach the invoice?
• A change order was done but never signed. What do you do?
• We bill cost plus on this job. How do you prepare a cost report the homeowner will read?
• A client is forty days late on a progress payment. What is your follow-up?

You are checking whether they have billed homeowners before, or only businesses.

Step 9: Run two weeks of handover

Week 1

Give access to QuickBooks or whatever you run, plus bank feeds and your job folders. They watch one full invoice run and one supplier payment, and write both down.

Week 2

They do the work. You review every invoice before it reaches a client.

Keep reviewing client-facing invoices longer than you would with a subcontractor business. A wrong number in front of a homeowner costs more than a wrong number in front of a GC.

From week three, a daily summary and fifteen minutes once a week is enough.

Step 10: Check at thirty days

• Are deposits sitting in the liability account, not revenue?
• Did every job get invoiced on its milestone schedule?
• Is every signed change order billed?
• Are allowance overages on the invoices?
• Does gross profit per job match what you expected?
• Is anyone over thirty days being chased?

If profit per job looks higher than it felt, deposits are probably still being booked as income. That is the most common error in residential books, and it is the easiest to miss.

What it costs

Cost depends on job count, transaction volume, how many bank accounts, and whether you need cleanup first. Residential contractors usually sit lighter on payroll than framers and heavier on client billing.

Wishup pricing for a dedicated bookkeeper is $999 per month part-time at four hours a day and $1799 per month full-time at eight hours a day. Cleanup is quoted separately.

Part-time covers most remodelers running three or four jobs at a time. Move to full-time once you have six or more active jobs or a crew on payroll.

If you would rather not do all this yourself

Everything above assumes you will find, vet, and onboard someone on your own. That works well if you have the time, and you end up with exactly the setup you want.

If you do not have the time, a managed service does the finding and the vetting for you. Wishup’s bookkeepers work inside your existing accounting software. You still set up the deposit account and write the change order rule, because nobody can do that from outside your business. The rest is handled.

Each engagement comes with a dedicated account manager, a manager behind the bookkeeper, end-of-day reports, and quick replacement if the person is not a fit.

If you build new homes rather than remodel, bookkeeping for home builders covers that side. For the general overview, see bookkeeping for contractors. To walk through your job list and billing setup, hire a virtual bookkeeper on a free call.

Frequently asked questions

Where does a customer deposit go in my books?

Into a customer deposit liability account. It moves to revenue as you complete and invoice the work. Booking it as income on day one overstates your profit and your tax bill.

Can a bookkeeper handle cost plus billing?

Yes. They code every receipt to the job and build the cost report you share with the homeowner. Agree the format before the first invoice, since homeowners read these line by line.

Who writes up change orders?

You do, or your project manager. Your bookkeeper bills them once signed and flags work that was done without one.

How do allowance overages get billed?

As a line on the next invoice, with the allowance amount and the actual shown separately. Homeowners accept overages far more easily when they can see both numbers.

Should my bookkeeper chase late homeowner payments?

For the routine follow-up, yes. Anything that turns into a dispute or a lien question comes back to you.
