Watch a proposal become a letter
Ninety seconds: scope three services, let the engine price them, send it, accept it, and watch the engagement letter assemble with the same schedules and the same fee. Nothing is copied across, because nothing was ever apart.

Nobody planned the retyping.
It happens because the documents are separate.
The proposal is a Word file. The letter of engagement is a different Word file, rebuilt from last year's. The fee exists in both, typed twice, and by the time anyone notices they disagree the client has already signed one of them. No one chose this. It is simply what happens when two documents describing the same agreement are two documents.
"The proposal said one fee, the letter said another. Neither of us typed it wrong — we typed it twice."
Where it sits
The proposal is the hinge
Everything before it is a conversation. Everything after it is delivery, and in a UK practice that means an engagement letter your professional body expects you to hold, an AML check that has to clear before work starts, and a set of statutory dates that were fixed before you quoted. The proposal is where all three become real.
- Enquiry
- Scope from the service library
- Engine prices it
- Client accepts
- Fee freezes
- Letter assembles
- AML clears
- Jobs open on their statutory dates
That sequence is the localisation
A proposal that does not lead to a letter, a check and a dated job is a US proposal tool with a British spelling. The scope comes from your service library, the number from the pricing engine, the letter from the accepted proposal and the clearance state from the same client record — so the obligations that follow a signature in the UK are already attached to the thing that was signed.
One accepted proposal is the record four other modules read from.

The build surface
Scope and price, on the same screen
Pick services from your own library and the fee resolves as you build. Proposal software for accountants that makes you price somewhere else and paste a total in has already lost the thing worth having, which is that the number and the scope cannot drift apart.
Every service input is classified as affecting the price, the scope, or both — so a pricing variable can never quietly change what the client agreed to, and a scope variable can never quietly change the fee.
The obligation, not the document
The letter your professional body expects, assembled from the proposal
In the UK the engagement letter is not optional paperwork; it is the document your supervisor asks to see. It should therefore not be a second file somebody rebuilds from the first. The accepted proposal is the record the letter assembles from — same services, same fee, same schedules — and it stays readable long after everyone involved has forgotten the conversation.
Entity types
Does a sole trader get the same paperwork as a family group?
No, and the proposal should know that before anyone starts editing. Sole traders, partnerships, LLPs, limited companies and family groups on one proposal, with a letter per entity where the situation calls for it, and the wording that belongs to each service travelling with it.
On acceptance
The fee that never reconciles
On acceptance the exact selection freezes — the tier chosen, the add-ons toggled, every line and the reason for it, dated and attributed. The letter states that figure. The invoice bills it. Nothing recomputes it, so there is no version of this where three documents disagree and somebody has to work out which one the client actually signed.
A change after acceptance is a variation — separately signed and linked to the original, so the full position is the original plus what has been agreed since.
Seen enough? Bring an engagement you are scoping this week.
Book a demoThe difference
A document, or a record
Most proposal software for accountants is very good at making a document look excellent. The question is not how many templates it ships. It is whether the fee, the scope and the version the client signed are still readable in eighteen months, when somebody asks.
| When… | A proposal documentBeautiful, sent, accepted, filed | A generic proposal toolBuilt for agencies, not practices | FigsFlowThe proposal is the record |
|---|---|---|---|
| The engagement letter is written | ✕Rebuilt by hand from last year's file. | !A second template, filled in again. | ✓Assembles from the accepted proposal. |
| You ask what the fee is | ✕Typed twice. Two answers, eventually. | !One answer, until somebody edits a document. | ✓Stated once and inherited by both. |
| The client accepts | ✕A PDF somebody has to go and find. | !A status change on the document. | ✓The selection freezes, dated and attributed. |
| One proposal covers three entities | ✕Three documents, built separately. | ✕One document. Entities are your problem. | ✓A letter per entity, on the right body template. |
| AML has to clear before work starts | ✕Tracked somewhere else entirely. | ✕Not the tool's concern. | ✓Clearance sits on the same client record. |
| The fee changes after signature | ✕Someone edits the file. | !A new version supersedes the old one. | ✓A signed variation, linked to the original. |
| Somebody asks, eighteen months later | ✕Find the PDF. Hope it is the signed one. | !An export, if the account is still open. | ✓The record reconstructs — scope, fee and version. |
One is a file somebody has to go and find. The other is a structure the letter, the check and the job all read from.

You write the proposal and you write the letter, so you are the person who retypes the fee. The record removes a job you never agreed to take on.
