By MSP Margin Editorial
Many MSPs start with a chart of accounts that has one income account, usually called services revenue, and a cost side that mixes payroll, software and hardware purchases together. It works for filing taxes. It does not tell you whether your managed services agreements are profitable, or whether hardware sales are worth the effort.
The fix is structural. Set up revenue accounts by service line and give each one a matching cost of service account. Then the profit and loss statement shows gross margin for each line every month, without a spreadsheet rebuild.
Why one revenue account hides the problems
MSP service lines have very different economics. Managed services are mostly your own labor and tools, and a well-priced agreement keeps a good share of each dollar. Hardware resale and license pass-through carry thin markups. Project work swings with how well you scope. Prepaid support blocks depend on how many hours clients actually use.
When all of that flows into one line, the blended margin moves for reasons you can't see. Here is an illustrative example. An MSP books $60,000 of managed services revenue with $27,000 of direct cost, a 55% margin. In the same month it sells $20,000 of hardware that cost $17,000, a 15% margin. Combined, revenue is $80,000, cost is $44,000, and gross profit is $36,000, which is a 45% margin.
Next month hardware sales double to $40,000 at the same 15% margin, so cost is $34,000. Managed services stay exactly the same. Combined revenue is $100,000, cost is $61,000, and the blended margin falls to 39%. Nothing went wrong in service delivery, but a single revenue account makes it look that way.
A sample structure by service line
The table below shows example accounts. The numbers and names are only a starting point; use what fits your offerings.
| Revenue account | Cost of service account |
|---|---|
| 4000 Managed services revenue | 5000 Managed services cost |
| 4100 Project revenue | 5100 Project cost |
| 4200 Hardware resale revenue | 5200 Hardware cost |
| 4300 Licensing and pass-through revenue | 5300 Licensing cost |
| 4400 Support block revenue | 5400 Support block cost |
Each revenue account has a cost account with the same last three digits, so 4200 pairs with 5200. That makes reports easier to read and mapping mistakes easier to spot.
Under each cost account, you can add sub-accounts where they help. Managed services cost might split into technician labor, RMM and security tools, and backup. Project cost might hold labor and subcontractors. Keep sub-accounts few enough that people code transactions consistently.
Decisions that make the structure work
Decide where technician labor goes. The most useful margin numbers include the labor that delivers each service. Many MSPs allocate technician payroll across service lines using time entries from the PSA, then book a monthly entry. Time spent on internal work, training or sales stays in operating expenses. Pick a method and apply it the same way every month.
Map PSA items and agreement types to the right accounts. If your PSA product catalog and agreement types point to the correct income accounts, invoices post to the right line automatically when they sync. Check the mapping whenever you add a new product or service.
Keep tools in cost of service when they deliver client work. An RMM, endpoint security or backup license used for client agreements is a cost of delivering managed services, not general overhead. Tools the business uses internally, like accounting software, belong in operating expenses.
Match the cost to the period. Annual tools paid upfront should go to prepaid and be expensed monthly into the right cost account. Otherwise one month's managed services margin takes the whole hit.
Once the structure is in place, a monthly report with revenue, cost and gross margin by line answers practical questions. You can see whether an agreement price increase is overdue, whether project overruns are eating profit, and how much of your top line is pass-through. It also gives a lender or buyer a clear picture of where profit comes from.
This article is general information, and the right chart of accounts depends on your services, systems and reporting needs. Review any changes with your accountant before you restructure accounts mid-year.
