Project Management for Service Businesses: Connecting Billable Work to Payroll
Agencies and software houses lose margin in the gap between the project tool and the payroll system. Here is how to close it and see real profitability per project.
If you sell your team's time — as an agency, a software house, a consultancy or a managed service — then your two largest numbers are what you bill clients and what you pay staff. In most companies these live in different systems, and nobody can put them side by side without a spreadsheet. That gap is where margin quietly disappears. The symptom: profitable revenue, unprofitable projects A company can be growing, billing more every quarter, and still be making less money, because a handful of projects are consuming far more delivery time than they were quoted for. Without cost and revenue in the same view this is invisible until year-end. The specific questions most service businesses cannot answer quickly: Which client is our least profitable, after delivery cost? How many hours went into that fixed-price project versus what we quoted? What proportion of the team's paid hours were billable last month? If we take this new project, who is actually free? Why two systems cannot answer them A project tool knows tasks and hours but not salaries. A payroll system knows salaries but not which project consumed them. Joining the two requires exporting both, matching people by name, allocating salary across projects by hand, and repeating the whole exercise next month. Almost nobody does that monthly. So the answer arrives quarterly at best, long after the decision it should have informed. You cannot manage project profitability on a quarterly lag. By the time the number arrives, you have already quoted the next three projects the same way. What connected looks like in practice When project delivery and payroll share one employee record, four things become possible without any reconciliation: Delivery cost per project, derived from logged hours against the salary of the people who logged them. Margin per project, sitting next to what has been invoiced and what has actually been collected. Utilisation per person, as billable hours against paid hours — the health metric for a service business. Capacity, because assignments and leave are in the same system, so "who is free in September" accounts for holidays. Making the boards actually get used None of the above works if the team does not update the board. The practical rules that make adoption stick: One board per project, and one column per real state. If a column does not change how someone behaves, delete it. Work in progress limits. A column with fourteen cards in progress is a column with nothing in progress. The card is the conversation. Comments, files and decisions belong on it, not in a chat thread nobody can find later. Time logs on the task, not on a weekly timesheet. Retrospective timesheets are fiction, and everyone knows it. Make the board the status report. If you also maintain a separate status document, people will maintain neither. Estimates versus reality Keep estimated hours on the task alongside logged hours, and review the gap at project close. Not to blame anyone — estimation is genuinely hard — but because the ratio is the single most useful input into your next quote. Most teams discover a consistent multiplier, and applying it turns quoting from optimism into arithmetic. Invoicing belongs here too The last hop is usually manual: work is delivered, someone raises an invoice in accounting software, and the link between what was delivered and what was billed exists only in someone's memory. Keeping invoices against the project means billed, collected, outstanding and overdue sit next to the delivery cost that produced them — which is the actual definition of knowing whether a project made money. That is the loop Project Help Hr&Payroll closes: the same employee record staffs the board, logs the hours, appears on the payroll run, and rolls into the project's margin report.
