A term sheet feels like the finish line. It isn't — it's the starting gun for due diligence, the deep examination where investors verify that everything you told them is true and that there are no landmines buried in your company. This is where deals slow down, get repriced, or quietly die, almost always over things that could have been fixed months earlier. The founders who close fastest are the ones who did the diligence work before the first investor conversation. Here's the checklist that actually matters.
What due diligence really is
Diligence is an investor's structured risk-check across your company's legal, financial, tax, and operational reality. They're not looking for perfection — every startup has rough edges — they're looking for surprises. A known, disclosed issue is manageable; an undisclosed one discovered during diligence erodes trust and gives the investor leverage to renegotiate or walk. The entire goal of preparation is to make sure nothing about your company is a surprise to you when it surfaces.
The corporate and legal file
This is where diligence starts and where new companies most often have gaps:
- Incorporation documents — certificate, MoA, AoA, and every amendment.
- Statutory registers and board/shareholder resolutions — properly maintained and up to date, not reconstructed the week before.
- ROC filings — all annual returns and event-based forms filed on time. A gap here is an immediate red flag; keep ROC compliance clean throughout.
- Cap table — a clean, reconciled record of who owns what, including the ESOP pool and any convertible instruments. A messy cap table is one of the most common diligence delays.
- Prior investment documents — SHA, SSA and any convertible notes or SAFEs, with terms that don't contradict what the new investor is being offered.
The financial file
Investors examine your books first and most closely. What they expect to see:
- Audited or finalised financial statements for available years, consistent and reconciled (year-end finalisation).
- Up-to-date management accounts — a current P&L, balance sheet and cash-flow position, not numbers that stop three quarters ago.
- A defensible financial model and projections — the numbers behind your pitch, built to survive being stress-tested (financial model and projections).
- Unit economics — CAC, LTV, margins and payback, clearly evidenced from your actual data (unit economics analysis).
- Bank statements reconciling to your books — a mismatch here is a serious trust problem.
If your books aren't current and clean, this is the single biggest thing to fix before raising — clean accounting is the foundation the entire financial diligence rests on.
Investors don't expect a flawless company. They expect a founder who knows exactly where the flaws are and has already dealt with them.
The tax and compliance file
Undisclosed tax exposure is a classic deal-killer because it's a liability the investor would be buying into:
- GST — returns filed, input credit reconciled, no unresolved mismatches (GST reconciliation).
- TDS — correctly deducted, deposited and filed, with no classification errors lurking.
- Income tax — returns filed, advance tax paid, no open demands.
- Any notices or assessments — disclosed and, ideally, resolved. An open notice discovered in diligence is far worse than one you disclosed and are managing.
The contracts and IP file
- Customer and vendor contracts — especially anything with change-of-control clauses, exclusivity, or unusual liabilities.
- Employment agreements and the ESOP scheme — properly documented, with IP assignment clauses so the company (not individual founders or contractors) owns what was built.
- Intellectual property — trademarks, and clear ownership of code and product. Investors want to know the company owns its core assets outright.
- Founder agreements — vesting, roles and any restrictive covenants.
Build the data room before you need it
All of the above lives in a data room — a single, organised repository you share with investors. The difference between a data room assembled calmly in advance and one thrown together mid-diligence is enormous: the first signals control and speeds the deal; the second signals chaos and invites deeper probing. Structure it by the categories above, keep it current, and you turn diligence from a scramble into a formality. This is exactly what our data room preparation and diligence support services are built to do.
The mistakes that slow deals down
- A cap table that doesn't reconcile — the most common single delay.
- ROC or tax filing gaps discovered mid-diligence.
- Informal ESOP promises with no scheme behind them (see our ESOP guide).
- IP owned by individuals or contractors rather than the company.
- Books that lag or don't tie to bank statements.
- Surprises the founder didn't disclose — the trust cost of which outweighs the issue itself.
Start before the conversation, not during it
The through-line of everything above is timing. Every item on this list can be prepared in advance and is painful to fix under deal pressure. Founders who begin assembling the data room, cleaning the cap table, and closing compliance gaps before they start pitching raise faster, negotiate from strength, and avoid the repricing that comes when diligence turns up problems. Our seed round preparation checklist covers the pitch-side of getting ready; this list covers the diligence side.
The bottom line
Due diligence is where deals are actually won or lost, and it rewards preparation over brilliance. A clean corporate record, current and reconciled books, no hidden tax exposure, clear IP ownership, and a well-organised data room turn diligence into a rubber stamp. Gaps in any of those turn it into a renegotiation — or a walk-away. If you're planning to raise in the next few months, the best time to run this checklist is now, while there's no deal clock ticking. Our funding advisory team gets founders diligence-ready before they pitch — talk to us and we'll pressure-test where you stand.
