Matter closure is the point where a legal matter moves from active work to a protected record, and post-closure matter controls decide what can still change after that date. Closing a matter rarely ends all activity. Outside counsel still send final invoices, finance still asks for accruals, and occasionally the work comes back. Your controls need a clear answer for each of those events.
The examples use SimpleLegal, whose matter features carry over as Onit moves SimpleLegal customers onto its Unity platform.
What are post-closure matter controls?
Post-closure matter controls are the configured rules that govern a matter after its closed date: which records lock, which financial activity continues, who keeps access, and how the matter can be reopened. They protect the integrity of completed matter data while leaving a controlled route for late invoices and renewed work.
Most departments design closure as a single status change and discover the gaps later. A firm submits an invoice three weeks after closing, an accrual request lands for a matter that settled last quarter, or someone edits a task on a closed file to fix a date. Each of those is a policy question. Answer them during design and the platform enforces the answers.
The matter lifecycle runs from intake through closure and archive, and closure is the stage most often left to defaults.
What should a matter closure checklist cover?
A matter closure checklist should confirm that every open item on the matter is resolved or deliberately carried forward before the closed date is set. Six or seven checks cover most departments:
- Open tasks and events. Complete or cancel every task and event, since they become hard to change once the matter closes.
- Documents. Confirm final versions of key documents, such as settlement agreements or orders, are filed against the matter.
- Budget and spend. Compare actual spend to budget and record the final position while the matter lead still remembers the context.
- Outstanding invoices. List firms with unbilled work and ask for final invoices within a set window, often 30 days.
- Accruals. Agree with finance how any remaining accrual will be released or carried.
- Closing data. Capture the closing reason, closing date, and responsible owner. A completeness target of 100 percent on these fields is realistic.
Where your platform supports required closing fields, put these checks on the closure form so a matter cannot close until they are filled.
What happens to tasks and events when a matter closes?
Tasks and events on a closed matter become read-only. In SimpleLegal, closed matter tasks are read-only for every user with access, regardless of their permissions, and the matter must be reopened before tasks or events can be updated.
That lock is the core of post-closure control. It means a closed matter’s timeline reflects what actually happened, and a later edit cannot quietly rewrite a deadline or an outcome. The same principle applies to most bulk updates: closed matters must be reopened before a bulk action can change them, and only matter template updates reopen and re-close them automatically.
The practical consequence is that cleanup has to happen before closure. A department that closes 200 matters in a year-end sweep, with open tasks still attached, will need to reopen a share of them to tidy up. Building the checklist into the closure form avoids that rework.
How does the invoice run-off period work after matter closure?
The invoice run-off period after matter closure is a configured number of calendar days during which invoices submitted on or after the closed date can still be processed. It gives outside counsel a window to bill final work without the matter being reopened. Check the setting early, because in SimpleLegal the run-off period is set at the system level with a default of 0 calendar days, which closes the window on the day the matter closes.
On Onit’s platform the period is set once at system level and defaults to zero calendar days, so no window exists until you configure one. Its length should match your billing guidelines. Three patterns are common:
- Zero days. Any invoice after closure is blocked from routine processing. This suits departments with strict guidelines and firms that bill monthly in arrears reliably.
- Fixed window. A single period, typically 30 to 90 days, applies to every matter. It is simple to explain and simple to test.
- Matter-specific. Longer windows for litigation or matters with known trailing costs, shorter for advisory work. It fits the work better but adds configuration and testing.
Put the same number in your billing guidelines so firms know the deadline before the matter closes.
Why do vendors receive accrual requests for closed matters?
Vendors receive accrual requests for closed matters when the invoice run-off period is set above zero calendar days. While the run-off window is open, the platform treats the matter as financially live for accrual purposes.
This surprises both sides. A firm that has sent its final invoice gets asked for an accrual estimate, and finance sees responses for matters it thought were finished. The behavior is consistent with the configuration, so the fix is communication and alignment.
Agree the run-off length with finance as part of eBilling accrual configuration, tell firms they may receive requests during the window, and ask them to return a zero estimate once final billing is complete. Review any accrual activity on closed matters outside the approved window each quarter. Late estimates slow finance down, and a 2025 survey of 100 finance professionals found half of finance teams take six or more business days to close the month. The target is zero unexplained requests.
What happens to vendor access when a matter closes?
Vendor access at closure depends on how your program configures it, so the closure process should include an explicit access decision. SimpleLegal and Onit’s Counsel Exchange portal both organize vendor collaboration around the specific matters a firm is assigned to, with files shared through the platform.
Counsel Exchange replaced CounselGO as Onit’s outside counsel portal, and firms often keep working in it during the run-off period. Decide in advance which of these applies:
- Retain during run-off. Firms keep access until the run-off window ends, so they can submit final invoices and documents.
- Remove at closure. Access ends on the closed date, which suits sensitive matters or firms with no outstanding billing.
- Reauthorize on request. Access is removed and restored only with approval if the firm needs it again.
Record the decision on the matter. A quarterly review of vendor access on closed matters, run alongside your wider legal vendor management practices, keeps old access from lingering.
When should a closed matter be reopened?
A closed matter should be reopened only when there is genuine new work or a correction that cannot wait, and only with recorded authorization. Reopening is the platform’s route back to editing, so reopening closed matters needs the same discipline as closing.
- Authorization. Name who can approve a reopen, usually the matter lead or a legal operations administrator.
- Reason. Require a reason from a short controlled list, such as appeal filed, settlement breached, or data correction.
- Audit trail. Keep the reopen date, approver, and reason on the record for every reopened matter.
- Revalidation. After reopening, check vendor assignments, invoice permissions, budget, and tasks before new work starts.
If reopens exceed a small share of closures, typically more than 5 percent, the closure checklist is probably letting matters close too early.
How should closed matters appear in reporting?
Closed matters should stay fully visible in reporting, filtered and labeled by status, because most spend and outcome analysis depends on completed work. SimpleLegal reporting treats closed as a reportable matter status, and its Active Vendors report shows the number of closed matters associated with each vendor.
Useful closed-matter reporting usually includes spend comparisons between open and closed matters, duration from open to close by practice area, and closures by reason. Add post-closure invoices and accruals as their own measures so run-off activity is visible. These sit naturally beside the legal department KPIs most teams already track.
How do you test post-closure controls before go-live?
Post-closure controls are tested with UAT scenarios that close a matter, attempt every blocked action, and confirm every allowed one. Ten to fifteen scenarios cover most configurations.
Test task and event edits on a closed matter, a bulk update across closed matters, an invoice inside the run-off window, an invoice after it, an accrual request during run-off, vendor access after closure, and a full reopen with revalidation. Run each scenario under at least two roles. Record the expected and actual result for each, and retest after any configuration change.
Conclusion
Matter closure works when the platform enforces decisions your department made in advance. Lock tasks and events, set a run-off period that matches your billing guidelines, align accruals with finance, decide vendor access on every matter, and govern reopening with a reason and an approver. Test each control under real roles before go-live, and report on closed matters as carefully as open ones. Done this way, a closed matter stays closed, and the exceptions are visible.

Frequently asked questions
What is matter closure in an ELM platform?
Matter closure in an ELM platform is the status change that moves a matter from active work to a protected record. Post-closure controls then decide which records lock, which invoices can still be processed, and how the matter can be reopened.
Can you edit a closed matter in SimpleLegal?
Tasks and events on a closed SimpleLegal matter are read-only for every user, regardless of permissions. The matter must be reopened before those records or bulk updates can change it.
What is an invoice run-off period?
An invoice run-off period is a configured number of calendar days after the closed date during which invoices can still be processed. On Onit’s platform it is set once at system level and defaults to zero days.
Why do law firms get accrual requests for closed matters?
Law firms get accrual requests for closed matters when the invoice run-off period is above zero days. The matter stays financially live for accruals until the window ends.
Should outside counsel keep access after a matter closes?
Outside counsel access after closure should follow a documented decision for each matter. Common choices are retaining access during run-off, removing it at closure, or restoring it only with approval.
Who should approve reopening a closed matter?
Reopening a closed matter should be approved by a named role, usually the matter lead or a legal operations administrator. Each reopen should record the approver, date, and reason.
