Stop work orders after a shutdown: the recovery playbook
Updated 6 October 2026
ZeroGov covers US federal contracting from the outside, so nothing here is an official SAM.gov notice. The lanes on the desk today are stop work orders issued during the lapse, the practical path to a modification when funding returns, and the documents a small contractor needs to keep before the ink dries on a new continuing resolution. Treat the timeline as the working assumption for the October 2026 lapse, and adjust the moment a signed vehicle is published.
What the stop work order is actually doing to your contract
Stop work orders are not terminations. They are a contracting officer's instruction to pause performance while the agency sorts out money, policy, or both. Most orders cite FAR 52.242-15, the Stop Work Order clause, which obligates the contractor to stop work, stop subcontractor work, and place further orders only as the contracting officer later approves. The clause also forbids unilateral cost cutting that would prejudice the government, which means a contractor cannot quietly lay off the cleared team to save payroll and expect reimbursement later. The clock that matters under the clause is the one hundred day maximum: the order must specify a duration or a reasonable estimate, and the agency must either extend it, lift it, or terminate for convenience before that cap runs out.
From the contractor side, a stop work order triggers three practical duties. First, freeze labour charges to the affected contract line items and start a separate cost code for idle time so the eventual claim is reconstructable. Second, send a written acknowledgment to the contracting officer within five business days that names the affected CLINs, the stop work date, and any subcontracts that need to be paused in turn. Third, start a daily incident log. Two line items per day are enough: the activity and the personnel. The log is the spine of any equitable adjustment under FAR 52.243-1 or any subsequent termination for convenience settlement under FAR Part 49.
It is worth noting that an agency can also pause work by other instruments. A partial stop work can be issued by modification, a class deviation can blanket a portfolio, or the contracting officer can simply decline to exercise an option. Each of these has a different claim posture, so read the instrument, not the press release. If the instrument is silent on the clause, ask the contracting officer in writing which clause governs. The answer determines whether you are running a stop work claim or a different conversation entirely.

The shutdown timeline and what each day costs a small contractor
The October 2026 funding lapse began on 1 October after the prior continuing resolution expired without a replacement. The pattern so far tracks the 2023 lapse more than the 2018 to 2019 episode, with most operations excepted under the Antideficiency Act and a tighter interpretation of excepted activities at the Department of Defense and the civilian agencies. The Federal Acquisition Regulation does not pause during a lapse, but the people who run acquisitions are largely furloughed, so contract actions slow, not stop. That is the first thing to communicate to a client or board: the FAR is alive, the contracting officer is often not at the desk.
Day one through day three is the period when most stop work orders actually arrive. Agencies tend to issue them in a single wave rather than piecemeal, because the workforce needed to draft them is itself excepted only for a narrow set of safety and property reasons. Expect the order to land by email from a SAM.gov registered address, with a contract modification number in the subject line and the clause cited in block fourteen of the SF-33 or the equivalent field in the awarded task order. If the modification number is missing, the order is not yet binding and you should reply requesting the formal instrument rather than stopping work on a verbal.
Day four through day seven is when the equitable adjustment exposure compounds. Idle labour, idle equipment, and extended subcontractor performance are all in scope under FAR 31.205-42 if the costs are reasonable, allocable, and supported. What is not in scope is the home office overhead that the contractor would have incurred anyway, which is why a daily log of the affected people matters. Day eight onward is when most agencies start issuing blanket deviations that say all stop work orders issued during the lapse will lift five business days after enactment, and that any costs incurred after that five day grace period are not reimbursable. Treat the grace period as the hard line for the claim package and stop accumulating costs the day the order lifts.
What this page is not
ZeroGov is an independent publication that covers US federal contracting from the outside. Nothing on this page is a SAM.gov notice, a GSA Schedule document, an SBA rule, or a contracting officer's instruction. We do not have access to the Integrated Award Environment and we cannot resolve Entity Validation issues on your behalf. If a link points to a .gov domain, it is because that is the canonical source, not because we speak for it.
This page is also not legal advice. The Stop Work Order clause, the Changes clause, and the Termination for Convenience clause each have decades of board and court interpretation that no blog post can replace. Use the playbook below to organise your file, not to skip a conversation with counsel before you sign a release.
The contract file you need before funding returns
The first draft of an equitable adjustment is built in the first ten days, not the last ten. Open a folder named for the contract and a subfolder for the shutdown period, dated from the day the stop work order arrived. Inside that subfolder, four documents are non-negotiable: a copy of the stop work order with the modification number; the daily incident log; the subcontractor notifications and their acknowledgments; and a memo from the program manager listing the work that would have been performed in the period if the order had not been issued. The memo is the document that often gets reconstructed from memory, and memory is what the Armed Services Board of Contract Appeals discounts most heavily.
Time impacts and pricing impacts belong in separate folders. The time impact is the schedule slip measured against the pre-shutdown baseline. The pricing impact is the cost of the slip and is what you will eventually propose under FAR 52.243-1. Keep the pricing folder clean of any reference to the time impact, because a contracting officer can read the pricing folder without needing to see the schedule argument and will form a first impression there. A clean pricing folder reads as a contractor who knows the difference between a request for equitable adjustment and a request for sympathy.
Subcontractor management during a stop work order is its own discipline. The prime is on the hook for the same equitable adjustment posture down the flow, and a stop work order does not by itself relieve the prime of the duty to settle. The fastest path is to mirror the prime's log at the subcontractor level and to write a parallel clause into any new subcontract issued during the lapse period that names the parent modification by number. Subcontractors who are not on a stop work order during a lapse are usually still on a slow payment cycle, because the agency that owes the prime is also the agency that is shut, and the prime's ability to pay down the chain depends on the funding flow restarting cleanly.
Filing the claim when the order lifts
FAR 52.243-1 gives a contractor thirty days from the date it receives a constructive change to submit a written claim. A stop work order that lifts with a schedule slip or a price exposure qualifies as a constructive change in the standard interpretation, even if the contracting officer never calls it that. The thirty day clock is not a friendly suggestion: the boards have repeatedly held that an untimely claim is a bar to the adjustment, not a preference. Mark the date the order lifted, add thirty, and treat that calendar entry as sacred.
The claim itself should be a single PDF with four sections. Section one is the narrative, in two pages or less, that names the contract, the modification, the period of performance, and the equitable adjustment sought. Section two is the cost breakdown in the same cost element format the contractor uses for its incurred cost submission, with idle facility cost segregated. Section three is the time impact analysis in narrative form, with the critical path noted and a CPM schedule fragment attached as an exhibit. Section four is the supporting documentation, which should include the stop work order, the daily log, the subcontractor notices, and any correspondence with the contracting officer's representative that bears on the adjustment. A claim that is more than one PDF tends to be read in pieces, and pieces are where the supporting documentation gets separated from the cost breakdown. Bind the package and label every tab.
Once the claim is in, the contracting officer has sixty days to issue a final decision under FAR 33.211. A contractor that does not receive a final decision in that window can deem the claim denied and appeal to the board, but the deemed denial has its own timing rules. Most small contractors will get an information request rather than a final decision, and the information request will ask for the same documents already in the claim package. Reply to the request on time, with a single binder, and copy the contracting officer on every response to a representative. The discipline of a single channel of communication is what separates a clean claim from a six month audit.
SAM.gov, CAGE, and the registration work that quietly fell behind
A lapse in appropriations does not pause SAM.gov renewals. The sixty day renewal window still runs, the Entity Validation queue still moves at its own pace, and the CAGE code is still active until SAM says it is not. The most common failure mode during a lapse is the contractor who assumes the system is paused along with the contracting officer and lets a renewal slip past the sixty day mark, only to discover on day ninety that the active registration is what allows the eventual modification to be paid. The fix is to set a calendar reminder in the first week of the lapse and to treat the renewal as a personal obligation rather than an agency one.
For contractors whose entity validation is still pending from before the lapse, the IAE migration on 6 October 2026 changes the way the queue is read. The case tracker is now the IAE help desk rather than the old SAM ticketing system, and the read only weekend of 3 to 5 October 2026 was the cutover. A pending ticket that was open before the cutover should now appear in the new system, but the response time is measured from the new open date. If the validation was the gating event for a pending option exercise, contact the contracting officer now and ask for a bridging modification that names the SAM entity status as the trigger rather than the calendar date.
CAGE codes themselves are not at risk during a lapse, but the address and banking data behind them are. A contractor that changed its registered address or its banking during the lapse will need to wait for the SAM record to refresh before a payment can route correctly. The fastest path is to make the change in SAM at least ten business days before a payment is expected, because the IAE queues banking validations separately from the rest of the entity record. Treat the banking screen as a checklist item, not a paid product, and the time it takes to validate will not surprise you.
What to ask the contracting officer on day one of the post shutdown period
Day one of the post shutdown period is when the contracting officer returns to a backlog of three weeks of work and a new continuing resolution to read. The first request in is the one that gets attention, so write it as a short email rather than a phone call. The email should name the contract, the stop work order modification number, the date the order lifted, and three questions: whether the agency intends to extend the period of performance, whether the contractor should submit a request for equitable adjustment or wait for a government initiated modification, and whether the agency will accept a partial period invoice for the work performed before the order arrived. The third question is the one that drives cash flow, and most agencies will answer it within the day.
The second question to ask is whether the agency intends to use a class deviation or a portfolio wide modification to lift all stop work orders at once. The class deviation is faster but it can also foreclose certain equitable adjustments by reference, so a contractor that has built a clean file during the lapse should prefer the individual modification path. If the agency insists on the class deviation, ask in writing for the deviation text and the policy memorandum that accompanies it. The text controls the claim posture, the memorandum is evidence of intent, and the two are not always the same.
The third question to ask, often forgotten, is whether any of the work that was scheduled to be performed during the lapse is now considered cancelled rather than delayed. The difference matters for the termination for convenience path under FAR Part 49. A delay is an equitable adjustment, a cancellation is a settlement. The contracting officer will not volunteer the distinction, because the agency would prefer to treat the work as delayed and the file as small. The contractor who asks the question is the contractor who gets the right clause applied, and the right clause is what determines the recovery.
The longer picture: how a lapse changes the next twelve months
A funding lapse is a stress test for the contract portfolio, and the results show in the next budget cycle. Agencies that spent the lapse drafting portfolio wide deviations will use those deviations as templates for the next lapse, which is why a contractor that understands this lapse's deviations is well placed to forecast the next one. The portfolio that comes out of a lapse with a clean file is the portfolio that gets the option exercised; the portfolio that comes out with a contested file is the one that is recompeted early. The next twelve months are where the option decisions are made.
For small contractors, the second order effect is more subtle. The small business set aside rules do not pause during a lapse, but the set aside decisions do, because the small business specialists are largely excepted only for actions tied to excepted contracts. A pending set aside appeal that was open before 1 October 2026 will not move until the specialists return, and a new set aside appeal filed during the lapse will sit in the queue behind the existing one. The expected delay is four to six weeks for the appeal to be assigned, on top of the normal processing time. The contractor that has a pending appeal should expect it to take longer and should not let the appeal clock expire during the wait.
Finally, the lapse is a reminder that the FAR is not the same document it was two years ago. The October 2026 remap of the FAR clauses is the largest reorganisation of the regulation since 1984, and a stop work order issued under the new Part 42 reads differently from a stop work order issued under the old Part 42. Read the clause cited in the modification, not the clause you remember from a prior contract. If the clause number does not match what you expect, ask the contracting officer in writing which version of the FAR governed at the time of award. The answer is the answer to which clause controls the adjustment, and the adjustment is what the file is for.
Quick answers
- Does a stop work order during a shutdown automatically lift when funding returns?
- Not automatically. The order lifts on the date named in a formal modification, which is usually five business days after a signed continuing resolution or annual appropriation. Until that modification is in the contract file, the order remains in effect.
- Can a contractor bill for idle time during a stop work order?
- Yes, if the costs are reasonable, allocable, and supported by a daily log that names the personnel, the dates, and the activity. Idle facility cost and idle labour are recoverable under FAR 31.205-42, but home office overhead that would have been incurred anyway is not.
- What is the deadline to file an equitable adjustment claim?
- Thirty days from the date the contractor receives the constructive change, which is usually the date the stop work order lifts with a schedule slip. A claim filed later than the thirty day window can be barred by the boards, so treat the deadline as a hard rule.
- Should a small contractor keep paying subcontractors during a stop work order?
- Yes. The prime remains on the hook for equitable adjustment down the flow, and a stop work order does not by itself relieve the prime of the duty to settle. Mirror the prime's log at the subcontractor level and write a parallel clause into any new subcontract issued during the lapse.
- Do SAM.gov renewals still run during a funding lapse?
- Yes. The sixty day renewal window still runs and the IAE help desk still processes tickets, although the read only weekend of 3 to 5 October 2026 was a cutover pause. A lapse in appropriations is not a pause in registration obligations, and a contractor that lets a renewal slip past day sixty will face a longer recovery than the contracting officer will.
