Inside LawAccounting's Payment Plans & Installment Billing: How Firms Collect From Clients Who Can't Pay All at Once (2026 Feature Spotlight)
Payment plans are how most family, criminal defense, immigration, and bankruptcy firms actually get paid — and they are almost always run on a spreadsheet and a reminder. LawAccounting's payment plan engine schedules installments against an invoice, automates collection and reminders, tracks delinquency, and keeps trust-funded plans on the right side of the IOLTA line.

💳 Why Payment Plans Break Firms That Run Them Manually
In consumer-facing practices, payment plans are not an exception — they are the business model. A family law retainer paid over six months, a criminal defense flat fee paid across the case, an immigration package paid in four installments, a Chapter 7 fee paid before filing. These firms do not have a collections problem so much as an administration problem.
Run manually, a payment plan requires someone to remember the schedule, run the card, notice the decline, chase the client, update the spreadsheet, and reconcile it against the invoice. Multiply by 200 active plans and you have a full-time job that produces no billable hours and fails silently when the person doing it is out.
⚙️ How the Payment Plan Engine Works
1️⃣ Create the schedule where the money is
A plan attaches to an invoice, a group of invoices, or an engagement with an agreed total. Set the number of installments, the amount (equal or custom), the start date, and the cadence — weekly, biweekly, monthly, or specific dates. A down payment can be taken immediately with the balance scheduled.
2️⃣ Store the payment method once, securely
The client authorizes ACH or card once through the secure payment portal. Credentials are tokenized by the payment processor — the firm never stores card data, which keeps the compliance burden where it belongs.
3️⃣ Charge automatically, post automatically
On each due date the installment is charged and the payment posts to the correct invoice and general ledger accounts without anyone touching it. Receipts go to the client automatically.
4️⃣ Escalate failures on a defined sequence
Declines and failed ACH debits trigger a configurable sequence: immediate client notification, automatic retry after a set interval, then escalation to the billing manager and responsible attorney. The plan status changes to delinquent so it appears in reporting rather than disappearing.
5️⃣ Report plans as first-class receivables
Active plans, scheduled future collections, delinquent plans, and expected cash by month appear in AR reporting alongside standard invoices — so a firm with $400,000 in scheduled installments can see it in the cash forecast instead of guessing.
Flexible Schedules
Equal or custom installments, any cadence, with an optional down payment — matched to what the client actually agreed to.
Automatic Collection
Tokenized ACH and card on file, charged on schedule, posted to the invoice and GL with no manual entry.
Failure Escalation
Configurable retry and notification sequence so a decline becomes a task, not a silence.
Trust-Aware
Installments into trust land in the client sub-ledger; fees release to operating only against an issued invoice.
Cash Forecasting
Scheduled installments feed expected cash by month — the single biggest blind spot in consumer-practice forecasting.
Full Audit Trail
Every authorization, charge, retry, failure, and modification is logged against the client and matter.
⚖️ The Trust Question Most Firms Get Wrong
Payment plans and trust accounting collide constantly, and the collision is where bar complaints come from.
If a client is paying an advance fee in installments, each installment is generally unearned when received and belongs in trust until earned. The temptation — deposit it straight to operating because "it's a flat fee and we've started work" — is exactly the shortcut that produces findings.
The engine handles both patterns explicitly. A plan can be configured to deposit installments to trust, where they sit in the client's sub-ledger until an invoice is issued and an earned-fee transfer is made. Or, where the funds are genuinely earned on receipt under your jurisdiction's rules and your fee agreement, installments post directly to operating. What it will not do is let you move unearned funds out of trust without an invoice behind them.
🎯 Where This Matters Most
| Practice Area | Typical Plan Pattern | What the Engine Solves |
|---|---|---|
| Family Law | Retainer replenished monthly, evergreen | Automatic replenishment into trust before the balance runs dry |
| Criminal Defense | Flat fee across the case, often pre-trial | Collection completed before the work concludes, with escalation on failure |
| Immigration | Package fee in 3–6 installments | High plan volume administered without adding staff |
| Bankruptcy | Fee paid in full pre-filing | Schedule tied to the filing date with delinquency visible early |
| Personal Injury | Client cost advances repaid at settlement | Cost tracking separated from fee collection |
- Payment plans are receivables with schedules — if the schedule lives outside accounting, collection depends on someone's memory.
- Automatic charging with a defined failure-escalation sequence recovers most of what manual plans lose to silent declines.
- Installments on advance fees generally belong in trust until earned; the system should enforce that, not rely on discipline.
- Set plans up at intake with authorization on file — completion rates are far higher than post-delinquency setup.
- Scheduled installments belong in the cash forecast; for consumer-facing firms they are often the largest single input.
