What proposal and contract software is
Proposal and contract software covers the two documents that turn an interested prospect into a committed client. First the proposal: the document that lays out what you will do and what it costs, which the client approves. Then the contract: the agreement that makes the engagement official and enforceable, completed with a signature. One tool for both means you move from pitch to signed deal without leaving the software or rebuilding the details.
The reason to think of them together is that they are not really two separate jobs; they are two stages of one job, closing the client. Treating them as a single connected flow, rather than two unrelated documents in two unrelated apps, is what makes the difference between a smooth close and a clumsy one.
Proposal vs contract: the difference
It helps to be precise about what each document is for, because they are often blurred. A proposal is persuasion plus definition: it makes the case for working with you and sets out the scope, deliverables, timeline, and price. Its job is to get a yes. When the client approves it, you have agreement, but not yet a binding commitment.
A contract is the binding part. It takes the agreed terms and makes them a legal agreement both sides are accountable to, covering not just scope and price but things like payment terms, ownership, revisions, and what happens if things change. It becomes effective when signed. In short, the proposal is where the client decides, and the contract is where the decision is made official. You need both, and they should say the same thing, which is precisely why keeping them connected matters.
Why they belong in one tool
Because the contract repeats the proposal. The client, the scope, and the price you carefully laid out in the proposal all reappear in the contract, now wrapped in legal terms. If those two documents live in different tools, that shared information gets entered twice, and every duplicate entry is a chance for the signed contract to drift from what was actually proposed and approved.
Keeping them in one tool solves this at the root. The approved proposal becomes the basis of the contract, so the scope and price carry forward instead of being retyped, and what the client signs matches what they agreed to. It also keeps the whole agreement, the pitch, the approval, and the signature, together on one client record, so anyone can see the full history of how the deal was struck rather than piecing it together from two systems.
The proposal-to-signed-contract flow
When proposals and contracts share a tool, closing a client becomes one continuous flow rather than a series of handoffs between apps:
- Draft and send a proposal with clear scope and pricing.
- The client reviews and approves the proposed work.
- Turn the approved scope into a contract for signature.
- The client signs the contract electronically.
- The signed agreement flows into the project and invoice.
Each step feeds the next on the same record. The approved proposal informs the contract, the signed contract confirms the deal, and the confirmed deal becomes the project and the invoice. Nothing is re-entered, and there is no moment where the agreement lives only in someone\u2019s memory between two tools. We cover the signing step in more depth in how to send a contract and get it signed online.
The cost of separate proposal and signing tools
The common setup is a dedicated proposal tool for the pitch and a separate e-signature app for the contract. Each is good at its job, and for a while the split feels fine. The costs are quiet but real. You pay for two subscriptions. You manage the same client in two places. And at the exact moment a deal is won, you copy the scope and price from the proposal into a contract in another app, introducing both effort and the risk of a mismatch.
Then, once the contract is signed, both tools hand you off again, because neither runs the project or the invoicing. So the won, signed deal gets typed a third time into your delivery and billing tools. The separate-tools approach works, but it turns one continuous close into a chain of manual copies, each a place for a detail to be lost or a version to diverge. Consolidating removes the copies, not by doing less, but by not splitting one deal across many apps.
Are electronic signatures valid?
For everyday client agreements, yes. Electronic signatures are widely recognized as legally valid, backed by laws like the ESIGN Act and UETA in the United States and eIDAS in the European Union. What matters in practice is that the signer clearly intended to sign, that there is a record of who signed and when, and that the signed document is kept unaltered.
That is why signing a contract online is now standard for agencies rather than a compromise: it is faster, it produces a clear record, and it is legally sound for typical engagements. For unusual, high-value, or regulated agreements it is always worth checking specific requirements with a lawyer, but for the client contracts most agencies send, an e-signature is both convenient and enforceable. This is general information, not legal advice.
What to look for
When you evaluate proposal and contract software, make sure it genuinely covers both halves and connects them to what comes next:
- Real proposals: clear scope and pricing, sent to the client, with acceptance tracked.
- Real contracts: documents that can be completed with a valid e-signature.
- Shared client record: proposal and contract attached to the same client, not two systems.
- Consistency from proposal to contract: approved scope carries into the agreement without retyping.
- A handoff into delivery: the signed deal becomes a project and an invoice.
A tool that only does proposals will still send you to a signing app; a tool that only does e-signatures cannot pitch. The ones worth choosing do both and keep them connected to the client and the work, so closing a deal is one flow from first draft to signed agreement to active project.
A proposal tool plus a signing tool, or both in one workspace
Agencies often pay for a proposal app and a separate e-signature app, then retype the deal again into their project and invoicing tools. Arpixa keeps proposals, e-sign contracts, projects, and invoices on one client record.
How Arpixa combines proposals and contracts
Arpixa keeps both halves of the close on the same client workspace. Proposals present scope and pricing and track acceptance, and e-sign documents handle the contracts and briefs that follow, completed with a signature. Because they share the client record, the approved proposal and the signed contract stay consistent instead of being rebuilt in a separate signing app.
And because both live in the same platform as projects and invoices, a signed agreement can move straight into delivery and billing, so the proposal, the contract, and the work all sit on one connected record. For the broader picture, see our guides to proposal software for agencies and how to hand off a proposal into a project.

Frequently asked questions
What is proposal and contract software?
Proposal and contract software handles two connected steps of winning a client in one place: the proposal, which presents the scope and price for approval, and the contract, which is the signed legal agreement that follows. Instead of a proposal tool and a separate e-signature app, one tool takes you from sending scope to a signed agreement, ideally keeping both attached to the same client record so nothing is rebuilt between them.
What is the difference between a proposal and a contract?
A proposal presents what you will do and what it costs, and the client approves it. A contract is the legally binding agreement that formalizes the engagement, usually completed with a signature. The proposal is about agreement on scope and price; the contract is about making that agreement enforceable. They are sequential steps in the same deal, which is exactly why handling them in one connected tool avoids re-entering the same details twice.
Why should proposals and contracts be in the same software?
Because they describe the same deal, and splitting them means duplicating it. When a proposal is accepted, the contract that follows repeats much of the same scope, client, and pricing. If the proposal lives in one tool and the contract in another, someone retypes those details and risks a mismatch between what was proposed and what was signed. One tool keeps the proposal and the contract consistent and on the same client record, so the agreement stays intact from approval to signature.
Is an electronic signature on a contract legally valid?
In most jurisdictions, yes. Electronic signatures are broadly recognized as legally valid for typical business agreements, supported by laws such as the ESIGN Act and UETA in the United States and eIDAS in the European Union. What matters in practice is clear intent to sign, a record of who signed and when, and an unaltered copy of the signed document. For high-stakes or unusual agreements, confirm requirements with a lawyer, but for everyday client contracts, e-signatures are standard.
Do I need separate contract software if I have proposal software?
Not if your proposal software also handles contracts and e-signatures. Many agencies end up with a proposal tool plus a separate signing app because their proposal tool stops at approval. A platform that covers both, proposals for scope and approval, and e-sign documents for the contract, removes that second subscription and keeps the whole agreement in one place. You only need separate contract software when your proposal tool cannot sign.
What should proposal and contract software include?
It should let you present scope and pricing, track proposal acceptance, and complete the contract with an e-signature, all tied to the client. The best tools go further and connect the signed agreement to delivery and billing, so an approved, signed deal becomes a project and an invoice without re-entry. Look for both halves, proposal and contract, plus the handoff into the actual work.
How does Arpixa handle proposals and contracts?
Arpixa keeps both on the same client workspace: proposals present scope and pricing and track acceptance, and e-sign documents handle the contracts and briefs that follow, completed with a signature. Because they live in one platform alongside projects and invoices, an approved and signed agreement can move straight into delivery and billing, so the proposal, the contract, and the work all stay on one connected record.
