The problem

The aging report shows how old the money is, and never why it is stuck

Once a month the receivables manager pulls the aging report from the billing system and goes looking for reasons: each client's e-billing portal, the engagement letter in the document system, and partners' inboxes, by asking. A full pass over the oldest matters takes days, so the reasons are stale by the time partners read them.

Meanwhile the oldest money waits longest. A pre-bill stays on a partner's desk long after the client's reason for holding it has passed, and rejection notices wait in portals for someone to read them. Collection tools built for business receivables do not fit, because the billing partner owns the client and a reminder in the wrong voice can cost the relationship.

The Problem Today

Firms lend clients months of fees for free, and the reason each matter is stuck hides in five different places.

From map to forecast

Nine screens that take law firm lockup apart, client by client

One screen per feature, in the order the work runs, with the role each one serves.

01Lockup map
A map of every client, sized by dollars locked and shaded by age
How it works
- 418 clients drawn as blocks, with 336 smaller clients folded into one
- A ruler splits the 118 days into 63 days of work in progress and 55 days of accounts receivable, against the 95-day target
- The darkest blocks are listed beside the map, with their days and dollars
- Ranked each morning: 1,140 matters, a named reason for 1,131 and 9 sent to partners
Chief financial officerSees the firm's lockup against its target in one picture, and which clients hold the oldest dollars, without waiting for the month-end aging pack.
02One client, split open
Any client splits open into its matters, grouped by why each is stuck
How it works
- A click opens a client's block into its matters, each tile shaded by age
- Tiles group under not billed, waiting on payment, rejected in the portal and disputed
- Beside them, five reasons in plain words, each with its citation and its dollars
- Here, $4.95M across 9 matters at 154 days, the oldest client in the firm
Receivables managerFinds out why her oldest client has been stuck for months without pulling the portal, the inbox and the engagement letter one at a time.
03Why it's stuck
A reason for each stuck item, cited to the record it was read from
How it works
- Each stuck item lists what was read: billing status, client emails, the engagement letter
- Each passage carries a citation that opens the source
- Here, pre-bill PB-8812 was held at the client's request until closing, and that hold ended 13 days ago
- A short nudge asks the partner to release all four pre-bills, $1.20M, or say which to keep
Billing partnerHears in a few lines, with the evidence attached, that the reason she held a pre-bill has gone, and decides whether to release it.
04Unbilled time
Unbilled time by age, by reason and by the partner holding each pre-bill
How it works
- $51.4M of WIP by age band, by practice group and by why it is not billed
- $12.9M sits in 74 pre-bills with 12 partners, each with the oldest days held
- A partner nudge is drafted once a pre-bill has been held 21 days
- The oldest unbilled matters show their status, such as pre-bill edits not returned
Receivables managerKnows which partners are holding pre-bills and for how long, without asking each of them in turn.
05Unpaid invoices
Portal rejections sorted by reason, each with the fix it needs
How it works
- 64 rejected invoices, $9.6M, read from each client portal's status and notices
- Grouped by reason: rate not approved, block billing, task code, timekeeper, expense
- Each reason carries its fix, such as splitting each entry into one task
- A rate the client has not approved goes to the partner, who decides
E-billing coordinatorWorks the 64 rejections by the fix each one needs, instead of opening each notice in each portal one at a time.
06Call note
Call notes for disputed invoices, with no reminder sent to the client
How it works
- The note sets the agreed expert budget beside what was billed: $96,000 over
- It cites the client email that approved the rebuttal expert
- The partner's choice is laid out: stand on that approval, or propose terms
- While an invoice is disputed, no reminder goes to the client
Billing partnerWalks into the call with the budget, the overage and the client's own approval in hand, and keeps the decision on the dispute.
07Next steps
A queue of the oldest matters, each step drafted in the voice it needs
How it works
- Matters with items over 180 days: $14.2M of old money, $21.9M on those matters
- Filters by step: 17 nudges, 7 resubmissions, 11 reminders, 3 call notes
- Client reminders go in the partner's voice, under that partner's standing approval
- Each draft can be edited, or rejected with a reason, before one approval sends the batch
Receivables managerApproves next steps on the oldest money in one sitting, where a full pass over those matters takes about three working days.
08Retainer top-ups
Retainer top-ups drafted from the floor in each engagement letter
How it works
- Trust balances set against the evergreen floor each engagement letter names
- 14 matters sit below their floor, $710,000 to request
- Each request cites its clause and goes in the billing partner's voice once approved
- Top-ups stay out of the lockup forecast until paid into trust
Trust accountantApplies a top-up only after the partner has approved it and the client has paid into trust, with no agent touching trust money.
09Lockup forecast
A forecast that shows what the drafts do to lockup days by year-end
How it works
- Weekly lockup days, actual to today and forecast to the firm's year-end
- 118 days as is, and 101 if the 38 next steps are sent, against a 95-day target
- A breakdown by type of step shows where the 17 days come from
- Each assumption sits beside its source in the firm's own payment history
Chief financial officerSees before anything is sent how far one batch moves the firm toward its target, and which assumptions the forecast rests on.

Thirty-eight drafted steps bring the year-end forecast from 118 to 101 days

Of $21.9M on the 38 oldest matters, $13.9M is expected in by year-end, judged from the firm's own payment history.

Next step	Matters	Expected cash of what is on them	Lockup days
Nudge to the billing partner	17	$5.4M of $8.6M	−6.6
Corrected portal resubmission	7	$2.6M of $4.1M	−3.2
Client reminder in the partner's voice	11	$4.5M of $7.3M	−5.5
Call note on a disputed invoice	3	$1.4M of $1.9M	−1.7

What an aging report shows only as old: four stuck matters explained

Reasons the agents found behind matters the aging report lists by age alone.

Statements sent to the wrong team

One invoice sat unpaid for 261 days because its statements went to an old payables address. The reminder goes to the right team, in the partner's voice.

A short payment left open

A client paid short and the balance stayed open for 244 days. The reminder says the last payment came in short and itemizes what is still owed.

A billing hold nobody lifted

A hold kept $620k of environmental permitting time out of two billing cycles. The nudge goes to the billing team, who can clear it before the next pre-bill.

Time the letter says should wait

$790k of arbitration time looks stuck, yet the engagement letter bills it when the hearing closes. The agents watch it and raise it again if the date slips.

Around the board

More of the lockup board: the drafts, the settings and the record

What the e-billing coordinator, the partners and the finance team open around the map.

Client lockup map with each block recolored by reason, split into not billed, rejected in the portal, disputed and waiting on payment — **The same map, by reason**One switch recolors each block by why its money is stuck: not billed, rejected in the portal, disputed or waiting on payment.

Corrected resubmission for an invoice rejected twice, for block billing and an unapproved rate, citing both rejection notices — **A rejection, corrected**Rejected twice: 31 entries combine more than one task, and one associate billed $640/h against an approved $590. The $9,200 write-down still needs the partner.

Client reminder in the billing partner's voice adding the purchase order number the client's payables team asked for, cited to the addendum — **The purchase order nobody sent**Unpaid 214 days because a payables request for a PO number went unanswered. The number was in the engagement letter addendum, so the reminder carries it.

An invoice whose reason is unknown: one receivables ledger line read, no draft written, and the billing partner asked to explain — **No source, no guess**An invoice 3 days past terms, with no portal status and no client message, gets no draft. The partner is asked instead, and her answer lands here.

Settings with lockup targets, reminder cadence, the quiet list, and each partner's writing style and standing approval for reminders — **Each partner's voice, and its limit**How each partner writes, and the standing approval for reminders in their name, up to the second notice. One partner has not granted it.

Audit trail of agent runs beside people's approvals, a write-off and a standing approval, with filters for agents, people and sends — **Who drafted, approved and sent**Each agent run and each person's approval, write-off and send in one record, filtered by agents, people or sends.

Six records behind each reason, from the billing system to the trust ledger

The agents read where the answer already sits, and cite it.

Time and billing systemWIP, pre-bills, invoices and payments, read for the aging and each pre-bill's status.

Client e-billing portalsInvoice status and rejection notices, mapped to the lines each notice names.

Finance mailbox and partner inboxesRead only, client threads only: holds, closings, purchase-order requests and disputes.

Engagement letters and addendaPayment terms, billing arrangements, purchase-order numbers and retainer floors.

Trust ledgerWhat is held for each matter, set against the retainer floor its letter names.

Law firm lockup questions finance teams raise before trusting a reason

What is law firm lockup management?

Law firm lockup management shortens the time between a lawyer recording time and the firm holding the cash. This solution ranks clients and matters by age, reads the billing system, the client's e-billing portal, the emails and the engagement letter to name why each one is stuck, and drafts the next step for the right person.

How does it decide why a matter is stuck?

The reason finder reads the billing status, portal notices, client emails and engagement-letter clauses, and names one reason with a citation to the record it came from. With no source, it marks the reason unknown and asks the billing partner.

Will it send reminders to clients in a partner's name?

Only under that partner's written standing approval, which the partner can withdraw at any time, and only up to the second notice. Disputed invoices and clients on the quiet list are left to the partner, and the receivables manager approves each send.

Can it fix invoices rejected in a client's e-billing portal?

The portal reader maps each rejection notice to the lines it names, and the draft splits block-billed entries or recodes task codes. A rate or timekeeper the client has not approved goes to the billing partner. The e-billing coordinator checks each resubmission before it goes.

How is the year-end lockup forecast worked out?

The forecast agent counts a dollar only when its reason has a next step and the client's own payment history says it is likely to pay by year-end. Each assumption is shown with its source, and retainer top-ups are left out until they are paid into trust.

Does it touch the client trust account?

No. The retainer checker compares trust balances with the floors in each engagement letter and drafts top-up requests. The billing partner approves each one, and the trust accountant applies the money once it is paid in.
