Winning felt like the finish line. It was the start of a different clock. A signed federal contract has at least four separate deadline types running at the same time, on different cycles, enforced by different people, and none of them send you a reminder.
Deliverable due dates
Your contract or task order spells out what's due and when, usually in Section F or an attached delivery schedule. These are contractual, not suggestions. Missing one can trigger a cure notice or, on the wrong contract, liquidated damages under the delivery terms. The fix is not memory. It's a calendar entry made the day you sign, not the week the deliverable is due.
If you run more than one active contract, this is where things slip. A CLIN due date on contract A and a report due date on contract B don't compete for your attention until they're both due the same week. That's exactly the kind of collision a shared pipeline board catches early: we built ours so every active award's key dates sit on the same worklist as your open bids, because the moment you win, you're still running a pipeline, just a different one.
Option-period exercise windows
Most multi-year federal contracts aren't one award. They're a base period plus option years, and the government has to notify you before it exercises each option, per FAR 52.217-9. That clause also sets a preliminary notice window, often 60 days before the option would expire. If the contracting officer misses that window, or if you miss confirming pricing or capacity in time, the option can lapse instead of extending. Track the exercise date the same way you track a deliverable. Don't assume the government's own tickler system catches it for you.
Invoicing cycles
Getting paid isn't automatic once work is done. Most agencies require electronic invoicing through the Department of Defense's Wide Area Workflow or a civilian equivalent, and invoices have to match the contract line items exactly or they bounce back for correction. The Prompt Payment Act sets the government's clock, generally 30 days from a proper invoice, but that clock doesn't start until your invoice is actually correct. A rejected invoice resets it. Submit on your own cycle, don't wait for the deliverable to remind you, and keep a copy of what you submitted and when.
Registration renewal
Your SAM.gov registration has to stay active for the life of the contract, and it expires annually if you don't renew it. A lapse doesn't automatically void an existing award, but per FAR 52.204-7 your registration does have to be active at the point you submit any new offer or receive any new award. If you're mid-performance on one contract and bidding the next, a lapsed registration can quietly cost you the next one while the current one keeps running. Set the renewal date the day you register, not the week it lapses.
The actual system that works
None of these four deadlines live in the same place by default. A spreadsheet works until you have three active contracts and a bid in flight. What holds up is one place where every date, deliverable, option window, invoice cycle, renewal, sits next to the bids you're still chasing, so nothing falls off because it moved to a different tab. That's the whole idea behind keeping your post-award work on the same board as your pipeline instead of a separate system you have to remember to open.
