BACK OFFICE

THE FINANCE BACK OFFICE FOR SUBCONTRACTORS.

QUICK ANSWER

SPM handles the finance back office for commercial subcontractors doing $1M to $12M: bookkeeping coded to the job, payables, billing and pay applications, receivables and retention, and a monthly close with bank reconciliations finished by the 10th. SPM does not process payroll, file taxes, do audit or review work, or handle HR, dispatch and estimating. Nobody at SPM is a CPA.

Contractors use the words back office for two different things. Some mean administration: HR paperwork, dispatch, scheduling and phones. Others mean the money side, everything between a job being worked and the cost and the cash both ending up in the right place. SPM does the second. When that part is missing, the close finishes in the middle of the next month and nobody can explain the bank balance.

THE DEFINITION

WHAT IT MEANS.

A construction back office is the set of behind-the-scenes jobs that keep a contractor's money moving and recorded: coding costs to jobs, paying vendors, billing customers, collecting receivables and closing the books each month.

A subcontractor's back office usually starts as one person: an office manager or the owner's spouse who does the bills, the invoices and the bank reconciliation on the side. It works until the company outgrows that person. It usually fails without warning, in a month when a pay application goes out late, a vendor is paid twice and the close goes past the 20th.

Outsourcing it changes who does the work and leaves the decisions where they were. The owner still approves what gets paid and what gets billed. The owner stops coding, following up and reconciling.

WHAT A BROKEN ONE LOOKS LIKE

THE SIGNS THE BACK OFFICE HAS OUTGROWN ITS PERSON.

01

The books close after the 20th

A report that finishes three weeks into the next month describes a job that has already been decided. Nobody could act on costs coded that late while the job was still in progress.

02

Billing goes out when someone has time

Pay applications sent after the general contractor's cut-off wait a full cycle, and each one costs 30 days of cash you already earned. Late or incomplete billing is the most common back office failure in a contractor's first $5M.

03

Payables and receivables live in two places

Bills stay in an inbox and invoices stay in a spreadsheet, so nobody can say what is owed to vendors, what is owed by customers or what is held in retention on any job.

THE FIVE JOBS

WHAT SPM TAKES OFF YOUR DESK.

1. Bookkeeping coded to the job

A chart of accounts and job cost codes built from how you estimate, with transactions coded weekly so job costs are current and comparable to the bid.

2. Payables coded to job and phase

Vendor and subcontractor bills entered against the job, approved before they post and tied to the commitments behind them.

3. Billing and pay applications

Regular invoicing is part of the monthly work. SPM also builds the schedule of values and drafts each pay application in your inbox. You agree it with the general contractor and your authorized signer signs it, and SPM sends it in officially.

4. Receivables and retention

A weekly review by aging bucket with one person responsible for each follow up call, and retention tracked by job as money you are owed.

5. The monthly close

Books closed and bank reconciliations finished by the 10th, so the numbers reach you while they can still change a decision.

FLAT MONTHLY FEE. NO SURPRISES.

Three tiers, priced by your trailing twelve month revenue. Which one you're in depends on how much of the work you want off your desk. We don't bill by the hour, and we don't do payroll. The one-time onboarding fee is in the table.

The onboarding fee covers migrating your books back to the start of your last taxable year and getting you fully operational in 60 days. It's billed once, with your first invoice. It's the same for all three tiers, and it moves with your revenue band. Your first month is prorated, and your monthly engagement starts on the first of the first full month.

Just want the setup? Onboarding only is the same onboarding work with no monthly service after it, one time, at the onboarding fee plus $2,000. Start a monthly engagement later and $2,000 counts toward it. It starts at $4,500, and the price for every band is on the pricing page.

The three tier columns are the whole price. Which one fits depends on how much of the work you want off your desk. No payroll. No hidden line items. The onboarding fee is right here in the table.

  • Online software only: QuickBooks, Sage, Viewpoint and similar. No VPN or hosted desktop.
  • Not in any tier: payroll, pay applications, collections on receivables.
  • Pricing valid through 2027.

COMMON QUESTIONS

FREQUENTLY ASKED.

It is the work behind the field: coding costs to jobs, paying vendors, billing customers, collecting receivables and closing the books. Some contractors also use the phrase for administration like HR and dispatch. SPM covers the finance side only.

SPM does no payroll, tax preparation, audit or review work, and does not handle HR, dispatch, scheduling or estimating. SPM is not a CPA firm: nobody at SPM is a CPA. Most clients keep a CPA for taxes and SPM works alongside them.

It is more. Bookkeeping comes first, and billing, receivables and the close are built on it. The output goes into a WIP schedule and a cash forecast, so the numbers get used.

Usually not. Many clients keep the person who knows the vendors and the crews, and SPM takes the coding, billing and reconciling from that person. SPM builds the system and the calendar, and your office staff keep the work that needs someone in the building.

Yes. SPM works with subcontractors anywhere in the United States and Canada through shared cloud accounts and video calls, so a contractor in Texas, Ohio or Ontario gets the same service as one in Arkansas.
