Why does billing leak in a professional services firm?
Because the people who record the time are the people who should be doing the work, and billing happens when they get to it. Time sits unbilled past the point a client expects an invoice, invoices go out late and are paid later, and receivables follow-up is a partner's awkward email at quarter end. A Finance Controller Digital FTE on ftes.ai owns that daily instead: it reconciles, flags, and drafts every morning, and a partner or the finance manager approves in minutes.
The work has a checkable answer in the billing system, which is what makes it a first-month function that touches no client matter.
What does the FTE reconcile each morning?
Time entries against invoices: which recorded hours have been billed, which are in draft, and which are unbilled past the firm's threshold, per client and per matter reference, with the entries listed. Invoices against payments: which have been paid in full, which partially, with the remittance evidence, and which are overdue by how many days. Fee arrangements against the billing: fixed-fee matters where recorded time exceeds the budget, flagged for the partner. Everything is proposed with the records behind it; the FTE reads the billing system through a dedicated account scoped to billing data and never opens matter files.
The morning brief lists what needs a decision: unbilled WIP past threshold, overdue receivables, and budget exceptions.
- Time to invoice: billed, in draft, unbilled past threshold
- Invoice to payment: paid, partial with remittance, overdue by days
- Fee arrangement: fixed-fee matters over budget, flagged
How are receivables follow-ups handled?
From approved templates, by stage: a courteous reminder at the first threshold, a firmer note at the second, a partner-signed letter at the third, each drafted with the invoice, the amount, and the days overdue filled in, and each sent only when a person approves it. The FTE never sends on its own, never proposes a discount or a payment plan, and never contacts a client whose relationship partner has marked the account as sensitive. A client who disputes an invoice is escalated to the relationship partner with a summary; the FTE does not argue an invoice.
Most firms find the first-stage reminder can earn autonomy within bounds from the record, because it is a template with a date; the later stages stay gated.
What does the FTE never do in a firm's finances?
It never posts an entry, never writes off or discounts an invoice, never agrees a payment plan, never changes a fee arrangement, and never opens a client matter file or reads correspondence. Write-offs, discounts, disputes, and fee changes are decisions a partner makes with the FTE's summary in hand. Its connection is dedicated, scoped to billing data, encrypted with a separately held key, and revocable in one logged action; its memory holds the firm's billing rules and templates, never client information.
The firm's compliance lead reads the remit before the first connection, and the quarterly connection review confirms the scope still holds.
How does the firm measure it?
Days from time entry to invoice, unbilled work-in-progress past threshold, and days sales outstanding, each against the last two quarters from the billing system's own reports, with the hours partners and finance staff spent on billing and chasing logged from the first week. The approval rate with send-back reasons shows where the templates or thresholds need tuning. Compare at the end of the first full quarter; a month captures setup and the first cycle of reminders, not a representative period.
The pattern most firms see first is unbilled WIP falling, because it is the number nobody was looking at daily.
What does the first month look like?
Week one: agree the thresholds and templates with the partners, mark the sensitive accounts, have the compliance lead read the remit, connect the billing system with a dedicated scoped account, and record the baseline. Weeks two to four: approve evidenced reconciliations and follow-up drafts in minutes a morning, send back with reasons, and read the reasons weekly. Day 30: read the FTE's own report, tune thresholds, and decide whether first-stage reminders have earned autonomy within bounds.
By day 30 the firm knows its unbilled WIP every morning for the first time, and the partners' quarter-end billing weekend has become a review of exceptions.
