Retainers and advance billing
Amounts collected before work is delivered need to be recorded and drawn down consistently so balances stay accurate across the engagement.

Bookkeeping for Professional Services
Billable time is the product. Administration shouldn't compete with it.
Consultancies, agencies, law and accounting practices, architects and engineers all run on engagements — and every engagement leaves an administrative trail. BookKeepersHQ helps keep invoicing, receivables and records organized behind the work.
How the back office works in professional services
A professional services firm bills for expertise and time, which means most of its financial activity is tied to engagements rather than inventory or storefront sales. Retainers are collected in advance, project fees are invoiced at milestones, hourly work is billed in arrears, and reimbursable expenses are passed through at cost. Each of those runs on a different rhythm, and each has to be recorded consistently for the numbers to mean anything at month-end.
Underneath that sit the firm's own obligations: software subscriptions, subcontracted specialists, insurance, travel, office costs and recurring vendor bills. Because these are usually modest and predictable individually, they are easy to postpone — until a quarter's worth of them need categorizing at once.
The pressure point in most firms is receivables. Professional services invoices are frequently paid on 30, 45 or 60-day terms, and the people best positioned to follow up on an overdue balance are the same people delivering client work. Without a maintained record of what has been invoiced, what has been collected and what remains outstanding, the follow-up simply does not happen on schedule.
As a practice adds clients and professionals, the volume of invoices, expenses and supporting documents grows in proportion to headcount. BookKeepersHQ provides the administrative layer that keeps that growth from landing on a principal's desk.
Common pressure points
Where the back office gets complicated
The recurring administrative work that tends to accumulate in professional services businesses.
Invoices across many engagements
Different clients on different billing cycles means invoicing is a continuous administrative task rather than a monthly event.
Slow-paying receivables
Extended payment terms make outstanding balances easy to lose track of without an up-to-date receivables record.
Reimbursable and pass-through expenses
Travel, filing fees and third-party costs have to be captured with documentation before they can be billed on accurately.
Subcontractors and specialist vendors
Work sent to outside professionals creates its own payables, records and payment history to maintain.
Month-end that competes with client work
Closing the month tends to fall in the same week as client deadlines, which is why it is so often deferred.

About Month-End SupportWhat this looks like in practice
A practice adds people. The administration adds up quietly.
A consulting firm may begin with two principals invoicing a handful of clients each month. Billing takes an evening, expenses are remembered easily, and the receivables list fits in someone's head.
Adding four professionals changes the arithmetic. There are more engagements, more billing arrangements, more travel and subcontractor costs to capture, and considerably more invoices going out and payments coming in. The follow-up on a 60-day balance now matters, because several of them are outstanding at once.
BookKeepersHQ provides the bookkeeping and administrative support behind that activity — invoices prepared and filed, receivables tracked, payables organized and accounts reconciled — so the principals stay on client work rather than the billing cycle.
Built to support growth
Your back office shouldn't become the bottleneck.
Growing practices generate more of everything: more clients, more engagements, more invoices, more vendors and more records. The informal habits that worked at two principals become difficult to sustain at ten.
BookKeepersHQ provides additional administrative capacity so a firm can handle greater activity without routine bookkeeping and recordkeeping consuming management's attention.
More business shouldn't have to mean more paperwork for the owner. With reliable support behind the practice, principals can spend more of their time serving clients, developing the practice and bringing on the next professional.
