How long does a business plan take?
A standard plan takes two to four weeks once the inputs are in hand. The variable is rarely writing speed; it is how long it takes to get complete, consistent inputs.
Typical timelines: financial model alone 5–10 working days; full business plan 2–4 weeks; feasibility study 1–3 weeks; investor plan with model 3–5 weeks. All assume inputs arrive promptly and the scope does not change.
Timeline by document
| Document | Working days | Main dependency |
|---|---|---|
| Financial model only | 5–10 | Cost and pricing inputs |
| Bank-loan business plan | 15–20 | Quotes, collateral details, repayment terms |
| Investor business plan | 15–25 | Traction evidence, raise details, model |
| Feasibility study | 10–20 | Sector research, operating assumptions |
| Market research summary | 5–10 | Defined segment and geography |
| Pitch deck support | 5–10 | Existing deck or plan, model |
| Proposal or company profile | 3–8 | Tender document, technical inputs |
What actually consumes the time
Research. A new sector with thin public data takes longer than a familiar one with visible competitors.
Modelling. A single-revenue business is straightforward. Multiple revenue streams, seasonality, debt schedules and scenarios multiply the work.
Review cycles. Each revision round needs your review, my revision and your confirmation. Two rounds typically add three to five working days in total.
Waiting. The largest and least visible cost. Supplier quotes, lease terms and licence details arrive on other people's schedules.
The dependency chain
| Stage | Depends on | Typical duration |
|---|---|---|
| Scoping call | Your availability | 30 minutes, usually within 2–3 working days |
| Scope and quote | Scoping call | 1–2 working days |
| Advance payment | Quote acceptance | 1–3 working days |
| Inputs collection | You, suppliers, landlord | 3–10 working days |
| Drafting | Inputs | 7–15 working days |
| Review and revisions | Your feedback | 3–5 working days |
| Final delivery | Payment terms met | 1–2 working days |
The chain is why a four-week plan can become six weeks without anyone working slowly.
How to make it faster
- Send supplier quotes and rent figures before the scoping call.
- Decide the funding amount and purpose early, and keep them stable.
- Nominate one person to give consolidated feedback.
- Answer questions in one batch rather than across a week.
- Do not change the concept after the draft.
What I will not do
I will not promise same-day or 48-hour delivery. Documents produced that quickly are either templated or unread. If a deadline is genuinely fixed and the scope cannot fit, I will say so at the scoping stage.

A realistic calendar for a bank-loan plan
| Week | Activity | Who |
|---|---|---|
| 1 | Scoping call, quote, advance payment | Both |
| 1–2 | Inputs: quotes, lease, cost data, existing accounts | Client |
| 2–3 | Research and model build | Consultant |
| 3–4 | Draft plan written | Consultant |
| 4 | Client review | Client |
| 5 | Revisions and final model | Both |
| 5–6 | Final files and submission preparation | Client |
That is five to six calendar weeks, not three, because the input stage sits inside it. Founders who already hold quotes and accounts can compress the first two weeks substantially.
What "rush" actually costs
When a deadline is close, something has to give. The options are:
- Reduce scope — a model and a shorter plan, rather than a full document.
- Use estimates — clearly labelled, with verification to follow.
- Parallelise review — the client reviews sections as they are drafted.
- Add resource — rarely possible for a single-consultant practice.
What does not work is compressing research or skipping the reconciliation between plan and model. Those are the parts that make the document defensible.
Planning backwards from a deadline
Start from the submission date and subtract:
- two working days for final checks and signatures;
- three to five days for revisions;
- seven to fifteen days for drafting;
- three to ten days for inputs.
If the result is in the past, the scope has to change. Better to discover that on the first call than three weeks later.
