How to track key dates and notice requirements for Software Development Agreements

Track software development dates by connecting each deadline to its contractual trigger, supporting evidence, notice requirements, and responsible customer owner. Start with the executed agreement and project documents, then separate milestone delivery, acceptance testing, defect correction, retesting, payment, and change-control events. The resulting tracker should show when action is required, what supports the calculation, how any notice must be delivered, and what remains unresolved. Counsel validates contractual interpretation; engineering, project, and finance owners supply evidence and maintain the operational record.

When to use this workflow

Use this workflow when a customer signs a development agreement, adds a statement of work, receives a milestone delivery, or inherits a project with uncertain acceptance status. Prioritize agreements where silence may produce deemed acceptance, customer dependencies affect delivery dates, or payment conditions affect ownership rights.

The scope is customer-side administration of contractual dates and notices, not complete project management or dispute resolution. This guide uses a US transactional orientation and an October 13, 2026 research cutoff. Interpretation and notice effectiveness depend on the actual language, governing law, and facts. Treat unresolved questions as assigned review items, not settled calendar entries. The steps below are workflow recommendations, not statutory deadlines.

What you need

Collect the executed master agreement, active SOWs, specifications, acceptance criteria, payment schedules, security schedules, amendments, and approved change orders. Preserve versions and identify document precedence before deciding which milestone schedule controls.

Obtain delivery emails, repository release identifiers, deployment records, test results, defect tickets, invoices, dependency requests, and previously sent notices. Compare these records with the contractual delivery requirements: a repository upload may not establish the required submission package or completion notification.

Identify customer owners for testing, business acceptance, access and test-data delivery, invoice disputes, security remediation, and legal notices. Obtain current designated notice addresses and relevant definitions of business days, business hours, and time zones. Distinguish unavailable attachments from provisions absent from the documents actually reviewed.

Use the template

The Software Development Agreements — Key dates and notices tracker connects each contractual event to its calculation and action evidence. Copy this table into your working document or spreadsheet. Use one row per actionable event, with separate rows for related clocks.

In Source / rule, record the document ID, version, clause or page, operative requirement, consequence of inaction, and relevant cross-references. Keep longer extracts in a linked working note. Trigger / evidence identifies both the contractual event and the preserved record establishing it.

Due / basis contains the date, counting convention, conditions, and uncertainty. Notice route records method, recipient, copies, required content, and effectiveness requirements. Owner identifies one accountable person; supporting reviewers belong in Action / proof. Use Status / gap to distinguish verified, provisional, awaiting evidence, and completed entries. Record internal targets separately from contractual deadlines, and link related rows by ID.

Step by step

1. Establish the controlling document set

Assign stable IDs to the master agreement, SOWs, amendments, and schedules. Compare the executed documents with the project team's working schedule. Do not treat a later date in a project plan as an agreed contractual revision without checking its authority.

Read precedence and amendment provisions alongside change-control language. Resolve conflicts affecting acceptance criteria, milestone dates, and notice routes. If an incorporated schedule is missing, request it and mark affected rows provisional. Verify OCR-sensitive dates and cross-references against the executed image.

Record in the tracker: source IDs and pinpoints, applicable versions, and an owner and action target for each missing document or unresolved conflict.

2. Extract separate events and their consequences

Create distinct rows for customer inputs, developer deliveries, acceptance objections, correction periods, retesting, invoices, payment disputes, cure notices, and relevant termination or renewal notices. Include contractual security-remediation and handover dates where applicable. Identify whose performance or response each row tracks.

Do not combine initial testing and retesting. One SEC-filed agreement permits initial milestone objections within ten days of the defined Acceptance Test Date, correction within twenty days of receiving the change request, and retesting within five days of receiving the modified deliverable. It also provides deemed acceptance for silence and separate final-deliverable testing rules (Pelican agreement, §§ 3.4–3.7).

Record in the tracker: each event's rule, performing party, consequence of inaction, and links to preceding or subsequent events.

3. Verify the trigger before calculating the deadline

Match the contractual trigger to evidence. Distinguish code delivery from delivery of required documentation, credentials, test scripts, or a completion notice. Engineering confirms what the package contains; counsel determines whether omissions affect the contractual trigger. Do not wait for that decision without maintaining a protective entry based on the earliest plausible start.

Record calendar versus business days, treatment of the starting day, any cutoff or time zone, and applicable holiday definitions. Do not automatically roll a contractual deadline falling on a weekend forward. If the contract is unclear, preserve alternative calculations for counsel and set an earlier internal target.

Record in the tracker: trigger timestamp, evidence reference, calculation basis, verified or provisional deadline, and the reviewer responsible for confirmation.

4. Build the notice instructions beside the date

Read the event-specific provision with the general notices clause. Determine whether an acceptance objection, invoice dispute, dependency response, or breach notice has separate requirements. Check substantive content as well as transmission: identify the deliverable, failed criteria, supporting tests, and requested correction where required.

Capture recipient, address, copies, permitted methods, effectiveness conditions, and proof to retain. One SEC-filed master agreement distinguishes notice effectiveness by method and business hours, but retains bracketed alternatives and an unfilled mailed-notice timing term. It supplies no completed mailing deadline (Exhibit 4.20, § 15.5).

Record in the tracker: matter-specific notice instructions, unresolved questions, approval owner, and dispatch or receipt evidence needed for closure.

5. Connect acceptance, payment, and change-control dates

Map payments to the SOW schedule, invoice conditions, acceptance provisions, and dispute process. Do not presume that failed testing suspends payment or that payment establishes acceptance. Where ownership documents or rights depend on payment, create a linked verification task rather than declaring title transferred.

The Pelican agreement refers fee dates to its SOW and combines present assignment wording with a payment-conditioned grant while reserving developer technology. This illustrates cross-clause review, not a conclusion about ownership timing (§§ 5.2, 6.1–6.2).

Separate schedule responses from fee approvals. Another filed agreement, subject to its dispute provision, treats customer silence for three days after receipt of the specified delay notice as acceptance of revised milestone dates but rejection of fee increases (Exhibit 4.20, § 4.3(b)–(c)).

Record in the tracker: linked row IDs, distinct response consequences, and legal or finance decisions needed before action.

6. Assign action owners and internal escalation dates

Give each row one accountable customer owner and identify supporting approvers. Engineering may establish failure evidence while counsel or an authorized business representative sends the objection. Finance needs time to assess invoice disputes before the response window closes. Include a backup when the owner will be unavailable.

Work backward from the deadline to allow testing, drafting, approval, and effective delivery—not merely dispatch where receipt controls. Configure calendar entries or tasks in the team's chosen systems and assign responsibility for updating them. These internal targets do not alter contractual periods.

Record in the tracker: accountable owner, backup or escalation recipient, internal target, and the evidence or decision needed next.

7. Close events with evidence and update dependent rows

Close a notice row after preserving the approved notice, attachments, transmission record, and evidence supporting effectiveness. Distinguish notice completion from resolution of the underlying defect. Close delivery and testing events with corresponding technical records.

When corrected software arrives, activate its retesting row using the new trigger. When parties approve a change, retain the superseded date and link its replacement to the authorizing document. Update related acceptance and payment entries only where the agreement or approved change supports that result.

Record in the tracker: completion proof, reviewer confirmation, replacement or dependent row IDs, and unresolved effects assigned to counsel.

Worked example

Fictional scenario: Alder Quay Health hires Northglass Code to develop a patient-scheduling integration. All parties, documents, clauses, and events are invented. The table is a historical snapshot taken on October 12, 2026, before the next response deadline.

SOW-A § 4 requires code, test scripts, and release notes before initial testing begins. Objections are due seven calendar days after complete delivery, excluding the delivery day. Section 4.3 provides a separate three-calendar-day response period after complete modified delivery, using the same counting convention. Both periods end at 5 p.m. Eastern Time, with no weekend extension; silence produces acceptance. MSA-A § 12 requires the designated notice email and legal copy, with effectiveness on confirmed receipt.

Code and release notes arrived October 5; required scripts arrived October 7. Counsel confirms October 7 as the trigger, making October 14 the initial deadline. Counsel sent an approved objection on October 9 and preserved confirmed receipt. A complete corrected package arrived October 10, creating an October 13 retesting deadline.

On October 11, the developer also alleged customer delay. MSA-A § 6 requires a revised schedule and dependency details in the specified notice before its three-calendar-day election period begins. The email references an unavailable attachment. Counsel has not decided whether it triggered that period.

The corrected package requires action before the original objection deadline. The timely initial objection does not complete retesting. The missing delay attachment creates uncertainty, not permission to ignore the message or invent its contents. The protective calculation preserves a response target while counsel resolves whether the contractual clock began.

Common mistakes

• Starting every clock at signature. Identify the actual delivery, invoice, correction, or notice trigger and preserve evidence.
• Using one acceptance period throughout. Separate milestone testing, final integration testing, and modified-code retesting.
• Treating defect tickets as sufficient notices. Use tickets as supporting evidence; verify content, recipients, delivery method, and effectiveness separately.
• Replacing dates with an unapproved schedule. Check amendment authority and retain both the operative date and proposed revision until resolved.
• Closing ownership tasks at repository delivery. Track any separately required assignment documents. Federal law separates copyright from ownership of the material object and requires signed written evidence for copyright transfers other than by operation of law. Repository access alone does not establish chain of title (17 U.S.C. §§ 202, 204(a)).

Final quality check

• Every contractual row has a controlling source, version, and exact pinpoint, or an expressly assigned source gap.
• Missing incorporated schedules and conflicting documents remain visible.
• Trigger evidence establishes the required package or identifies competing interpretations.
• Counting units, starting-day treatment, cutoffs, and protective dates are clearly distinguished.
• Notice instructions address required content, recipient, method, and effectiveness.
• Acceptance, correction, retesting, payment, and change-control rows are distinct but linked.
• Open issues have accountable owners and action targets; completed events retain proof without implying unresolved defects are cured.

Frequently asked questions

Should we calendar a deadline before delivery is verified?

Yes, as a clearly marked protective or provisional entry. Use the earliest plausible trigger, preserve missing evidence, and assign verification. A protective date is not a conclusion that delivery was contractually complete.

Does sending an objection stop the payment clock?

Do not assume so. Read the payment schedule, acceptance provisions, invoice-dispute process, and express linkages. Track the objection and payment obligations separately until counsel confirms their interaction.

What if the contract does not specify a time zone?

Flag the omission for counsel using the agreement and relevant facts. Set an earlier internal target where practicable, but do not silently insert a contractual time zone or cutoff.

How often should the tracker be updated?

Update it whenever delivery, correction, an invoice, a notice, or an approved change affects an event. Review open rows at a cadence suited to the shortest active window; weekly meetings may miss short retesting periods.
