Financial Model Approval Workflow for Consultants & Finance Teams

Consultants sell clarity under uncertainty. Clients buy confidence that the numbers they approved are the numbers they paid for. When model review happens in email — “see attached_final_v3_REAL.xlsx” — you get endless rounds, ambiguous sign-off, and invoices challenged after the fact.

This workflow adapts Zlaip’s Agree → Deliver → Approve pattern to finance deliverables: lock terms, upload Excel or CSV to Review Workspace, review on cells, bound revisions, then Approval Lock before payment.

Step 1 — Agree: define the model package in the contract

Before work starts, lock what “done” means for this milestone:

Vague SOW language (“ongoing model support”) is how scope creep eats margin. Use Agreement Lock™ so both sides see the same terms.

Step 2 — Deliver: upload the workbook to Review Workspace

1. Finish the milestone package locally (Excel, export from Sheets, or CSV where appropriate)
2. In Accountability Chat, Upload for review on the milestone
3. Client receives a review session — opens the spreadsheet canvas with tabs and cell selection
4. Optional: AI Asset Review flags wrong-file risk and objective gaps (AI review for Excel)

Do not rely on “file attached in email” as the system of record. The uploaded session is versioned on the agreement timeline.

Step 3 — Review: feedback on cells, not in threads

Strong finance review comments are specific:

• “Assumption B14 — churn should be 4.2% per board deck, not 3.8%”
• “Debt schedule does not foot to balance sheet line 42”
• “Remove hidden scenario tab before board distribution”

In Zlaip, reviewers select cell ranges; comments store sheet + coordinates so replies stay anchored when you ship v2.

Collaborators (controller, bookkeeper, CEO) can comment if invited — but only the designated approver binds Approval Lock.

Step 4 — Revise: bounded rounds, then change orders

When revision rounds are included in the contract:

• Each published revision request consumes a round (visible in Accountability Chat)
• When rounds are exhausted, further structural changes belong in a Change Order™ — new milestone, new fee, new scope

This protects consultants from “one more scenario” loops that were never in the SOW.

Step 5 — Approve: Approval Lock before invoice

Informal OKs (“numbers look directionally right”) do not protect you in a dispute. Approval Lock records:

• Who approved
• Which review session / file version
• Timestamp on the agreement timeline

After lock, Payment Release Gate™ opens invoice, retainer draw, or escrow release per your payment pattern.

For evidence standards, see Proof of client approval for payment disputes.

Roles in a typical engagement

When to use Word vs. Excel in the same project

Many finance engagements mix formats:

• Excel — models, budgets, reconciliations (spreadsheet review guide)
• Word — board memos, policy docs (Word & payslip review)
• PDF — signed exhibits or static board packs

One agreement timeline carries all milestone types — same revision and payment semantics.

Checklist before you send the model

• Deliverable label matches filename and cover tab
• Expected sheets present (per DoD)
• No client template placeholders left
• Approver knows they must use Review Workspace, not email reply
• Revision round count communicated upfront
