How do I collect payment right after a contract is signed?

Tools that combine both

PandaDoc, a document and e-signature platform built around proposals, quotes and contracts, has genuine native payment collection built into its signing workflow, confirmed on its own integrations page, connecting to Stripe, PayPal, Square, Authorize.net and QuickBooks Payments. The signer reviews, signs and pays on the same page, with the payment step built into the document itself rather than a separate link. This is available on its Business plan, confirmed at $49 a seat a month on annual billing.

DocuSign, a platform for sending documents out for legally binding electronic signature, offers "DocuSign Payments" as a feature, confirmed directly on its payments page, connecting to six gateways, Stripe, Authorize.net, Braintree (powered by PayPal), Cybersource, Elavon and Zuora, letting a signer pay at the point of signing, with the payment folded into the agreement's audit trail. It's included with Business Pro and Enterprise Pro eSignature plans, confirmed at $45 a user a month for Business Pro on annual billing. One detail worth knowing: DocuSign itself doesn't charge a separate payment-processing fee on top, you pay your chosen gateway's own transaction fees directly to that gateway, Stripe's or Authorize.net's published rates, not a DocuSign-specific markup.

HubSpot's Quotes tool, confirmed directly on HubSpot's site, combines e-signature and payment collection on a single branded page too, available on Revenue Hub's Professional and Enterprise editions. If your contracts are simple sales quotes rather than longer legal agreements, and you already run HubSpot, this is often the simplest native option of the three, since it doesn't require adding a separate platform at all.

Outside these three, the honest picture gets thinner. QuickSigner, an e-signature platform for signing PDFs and Word documents with AATL-certified, legally binding signatures, doesn't list a payment-collection feature anywhere on its own site as of this writing. SignWell and Dropbox Sign, both esign tools with their own documented APIs, also don't confirm a native payment feature on their own pricing or integrations pages. If payment-at-signing in one motion is the specific thing you need, that narrows your realistic choices to PandaDoc, DocuSign on its higher tiers, or HubSpot Quotes if you're already in that ecosystem.

Separate payment links: the common workaround

For any esign tool without a built-in payment step, the realistic pattern is a separate payment link sent immediately after signing completes, Stripe Payment Links, PayPal.me or a similar link, or a Square invoice, triggered either manually the moment you see a signing-complete notification, or automatically through the same webhook used for other post-signing automations (see my signing alert guide for the webhook mechanics this depends on).

The honest tradeoff here is real: a separate link is a second step the client has to take, which means a second chance for them to put it off. The gap between "signed" and "paid" with this approach is measured in hours or days for most businesses, not the instant handoff a native combined flow gives you. For low-value or trust-based relationships, that gap is rarely a real problem. For anything where getting paid promptly actually matters, a deposit collected at signing (below) or a genuinely combined tool closes that gap more reliably than hoping the follow-up link gets clicked.

A worked example

Say a small design studio closes roughly 15 projects a month, each needing a signed agreement and a 50 percent deposit before work starts, currently handled as two completely separate manual steps, send the contract, wait for the signature, then separately remember to send a Stripe Payment Link. With a webhook-triggered automation, QuickSigner's or SignWell's completion webhook firing a Zapier step that generates and sends a Stripe Payment Link automatically the moment signing completes, that second manual step disappears, and the average gap between signing and the deposit actually arriving shrinks from however long it takes someone to remember to send the link, often a day or more, to essentially the time it takes the client to open the next email. Switching to PandaDoc or DocuSign Business Pro would close that gap even further, down to literally the same page, but for a studio already comfortable with its current esign tool, the webhook-triggered link is a meaningfully cheaper fix than a platform migration, and it gets most of the benefit.

Common mistakes

• Treating a sent payment link as a received payment. Don't mark a deal or project as fully paid until the payment actually clears, not just when the link went out. A client can receive a link and still not act on it for days.
• No reminder if the link goes unused. If someone hasn't paid within a set window, a single automated reminder recovers a surprising amount of otherwise-lost or delayed revenue, and it's a simple addition to the same automation that sent the original link.
• Mixing up which gateway's fees apply. With DocuSign Payments specifically, remember the transaction fee comes from your chosen gateway, not DocuSign itself, so compare gateway fee schedules directly rather than assuming they're baked into your DocuSign subscription.

Deposits and receipts

A deposit-at-signing structure, collecting a portion of the total immediately, with the balance due later on a separate schedule, is a reasonable middle ground when a full combined signing-and-payment flow isn't available or isn't worth building yet. It gets some money moving the moment the contract is signed, which also serves as a meaningful signal of real commitment from the client, while the remaining balance follows your normal invoicing process.

Whichever route you use, a receipt confirming the payment actually went through, separate from the signed contract itself, matters more than it might seem. The signed contract proves what was agreed to. The receipt proves what was actually paid, and when. Keeping these as two distinct, clearly dated records avoids a genuinely common dispute: a client claiming they paid in full when only a deposit went through, or disputing a charge months later with no clear record tying the payment to the specific signed agreement it was for.

A practical habit worth building in regardless of which tool you use: reference the contract's own identifier, a document ID, a quote number, whatever your esign tool assigns, directly on the payment record or receipt itself. Without that link, reconciling a bank statement full of payment references against a folder of signed contracts months later becomes genuinely tedious, and it's a problem that costs nothing to prevent upfront but real time to untangle after the fact.

How I'd approach this

When a client tells me they're losing money to the gap between signing and getting paid, slow follow-through on a separate invoice, clients who sign and then go quiet, I look first at whether their existing esign tool actually has a native payment option they're just not using yet, since that's the cheapest fix if it exists. If it doesn't, and the volume justifies it, a webhook-triggered payment link that fires automatically the moment signing completes closes most of that gap without needing a full platform switch. For a business where this is a recurring, meaningful amount of lost or delayed revenue, it's worth treating as seriously as any other broken part of the sales process, not just a minor annoyance to live with, especially once you can put a real number on how much it's actually costing in late or missed payments over a typical month. Get in touch if you want this actually fixed rather than patched with another manual reminder.
