Getting the contract signed and the deposit paid in one step
Short answer: There are two realistic ways to collect a signature and a deposit together: pair a dedicated e-signature tool with a separate payment link, or use a field service or estimating tool that has both signing and payment collection built into the same estimate. The combined-tool approach is less setup but ties you to that platform's payment processing fees, typically in the 2.5 to 3 percent range plus a small fixed fee per transaction. The two-tool approach costs a bit more friction but lets you choose the cheapest processor for your volume. Either way, confirm the actual fee on the vendor's own pricing page before committing, since these rates get adjusted over time.
You want the customer to sign the contract and pay the deposit in the same moment, not as two separate follow-ups that give them time to have second thoughts.

A signed contract with no deposit attached is weaker than it should be, not legally, but practically: a customer who has not put any money down has an easier time canceling, going quiet, or shopping around further before committing. Collecting both in the same step, right after the quote is accepted, closes that gap, and it is genuinely doable on a phone in the time it takes to explain it. Payment options for small firms are in how to take deposits and payments online without a tech person.
The two real options
Option one: a combined tool that signs and collects payment in one flow. Several field service and estimating platforms let a customer approve an estimate and pay a deposit on the spot, inside the same screen. Housecall Pro, a field service management platform for home service businesses, is a common example in this category, covering quotes, scheduling, invoicing and payment collection, with card processing fees starting at 2.59 percent and a 1 percent fee on bank payments, according to its own published rates as of this writing. The appeal is obvious: one screen, one tap, no handing off between two different systems mid-conversation with the customer. The tradeoff is that you are locked into that platform's payment processing rate, which may not be the cheapest option available to you depending on your typical deposit size and monthly volume.
Option two: a dedicated e-signature tool plus a separate payment link. Sign the contract with an e-signature tool, then immediately send a payment link from a payment processor like Stripe or Square for the deposit itself. Stripe's payment links let you generate a no-code checkout link in minutes without building a website integration, and its commonly published US rate for card payments has historically been 2.9 percent plus 30 cents per transaction, though I was not able to confirm that exact current figure live while researching this article, since Stripe's pricing page redirected to a different country's rates during my check. Confirm the current US rate directly on Stripe's pricing page before relying on it. This approach costs a bit more friction, two links instead of one screen, but it separates your signature tool from your payment processor, which means you can shop the payment side for the best rate independently and switch processors later without touching your contract workflow at all. Tool choices are in best e-signature for contractors and field service.
The actual steps
- Prepare the contract with the deposit amount already written in. State the number plainly in the document itself, not just verbally, so the signature covers agreement to that specific amount.
- Send the contract for signature first. Whether that is inside a combined platform or a standalone e-signature tool, get the signature before asking for payment, since a signed agreement is what the payment is actually securing.
- Trigger the payment request immediately after signing. In a combined tool this usually happens automatically on the same screen. With two separate tools, send the payment link the moment the signed contract comes back, while the customer is still engaged, rather than queuing it for later. Timing is covered in how to collect payment after a contract is signed.
- Confirm both landed before leaving or ending the call. A signed contract with a pending, unpaid deposit is a loose end that is much easier to close in the moment than a day later, since every extra hour that passes gives a customer more room to have second thoughts or get a competing quote.
- File the signed contract and the payment receipt against the same job record. If a question comes up later about what was agreed and what was paid, you want both documents in one place, not split across two systems with no obvious link between them.
Fees to expect, and why they are worth comparing
Payment processing fees in this space generally run somewhere in the 2.5 to 3 percent range per transaction, plus sometimes a small fixed fee, though the exact number varies by processor and by how the payment is collected (a tapped card, a typed card number, and a bank transfer are usually priced differently from each other). On a $500 deposit, the difference between a 2.6 percent rate and a 2.9 percent rate is only a few dollars, which rarely matters for an occasional job. It adds up faster than most contractors expect once you are collecting deposits weekly, where even a half-point difference becomes real money across a year. This is the actual reason to look past the convenience of a single combined tool and at least check what a dedicated payment processor would charge for your specific volume, even if you end up sticking with the combined option anyway for the convenience. It is also worth checking whether your processor's quoted rate applies the same way to every payment method you plan to use, since a rate advertised for a tapped or inserted card is sometimes meaningfully lower than the rate for a manually typed card number, which matters if you are frequently collecting deposits over the phone rather than in person. Plans and fees are compared in invoicing app for contractors.
Handling refunds and cancellations honestly
A deposit only works as protection if your refund policy is clear before the money changes hands, not negotiated after a job falls through. Write the refund terms directly into the same contract the deposit is attached to: whether the deposit is fully refundable if the customer cancels before work starts, partially refundable after a certain point, or non-refundable once materials have been ordered or scheduling has been locked in. Vague language here, "deposits are generally refundable," creates exactly the kind of dispute a deposit is supposed to prevent. Most payment processors, including the ones mentioned above, support partial or full refunds back through the same transaction, but the processing fee on the original charge is usually not returned to you even when you refund the customer in full, which is worth knowing before you promise a customer their deposit back dollar for dollar.
One mistake worth naming directly: collecting a deposit before the scope is fully settled, then having the scope change before work starts. If a customer signs, pays a deposit, and then wants to adjust the job before anyone shows up, treat that the same way you would treat a change order mid-job, a new signed agreement reflecting the updated scope and price, rather than just verbally agreeing to the change and hoping the original paperwork still covers it.
A worked example
A general contractor collecting a $2,000 deposit on a $10,000 kitchen remodel, at roughly 2.9 percent, pays about $58 in processing fees on that one transaction. Across 20 similar jobs a year, that is close to $1,160 in fees from deposits alone, before counting the fees on final payments. That is not a reason to avoid collecting deposits, an unsecured contract is a far bigger risk than a processing fee, it is a reason to actually read the fee schedule before picking a tool rather than assuming all combined platforms charge roughly the same rate, because they do not always.
How I'd approach this
For a contractor doing a handful of jobs a month, the combined-tool approach is usually the right call, the convenience is worth more than the fraction of a percent you might save elsewhere, and fewer steps means fewer customers who stall between signing and paying. Once deposit volume gets real, several jobs a week with meaningful dollar amounts attached, it is worth an hour comparing your current processor's rate against one or two alternatives, since that is where the savings actually show up. If your contract-and-deposit flow is spread across several disconnected tools right now, a signing tool here, a payment link copied from a different app there, a separate spreadsheet tracking which jobs are actually paid, that disconnection is usually fixable, and building one connected flow so a signed contract automatically triggers the right payment request is exactly the kind of work I do. Get in touch if that is genuinely where you are stuck.
Questions people ask
What's the fastest way to collect a signature and a deposit together?
A combined estimating or field service tool that supports both in the same screen, like Housecall Pro, is the fastest, since the customer never leaves the app between signing and paying.
Is it cheaper to use two separate tools instead of a combined one?
Sometimes, depending on your volume and the combined tool's specific rate. It is worth comparing a standalone payment processor's published rate against your estimating or field service platform's own processing fee before assuming either is cheaper.
What's Stripe's exact current fee for a US deposit payment?
Its commonly cited published rate has been 2.9 percent plus 30 cents per transaction, but I was not able to confirm that exact figure live while researching this page, since its pricing page redirected to a different region's rates during my check. Confirm the current number directly on Stripe's own pricing page before relying on it.
Should the deposit amount be written into the contract itself?
Yes. Stating the specific deposit amount in the signed document, not just discussing it verbally, means the signature covers agreement to that exact number, which matters if the amount is ever questioned later.
Can I collect a deposit before the contract is signed?
You can, but it reverses the logical order. A deposit is meant to secure a signed agreement, so getting the signature first, then the payment, keeps the paper trail straightforward if either side ever disputes what was agreed.
Do ACH or bank transfer deposits cost less than card payments?
Often yes. Housecall Pro, for example, publishes a 1 percent fee on bank payments versus card processing starting at 2.59 percent. The tradeoff is that bank transfers can take longer to clear and some customers find a card easier to use on the spot.
