The enterprise word for this is "quote-to-cash," and it usually comes with a CPQ module, an implementation consultant, and a sales call before you see a price. You do not need any of that to send a quote and get paid for it. You need one thing the enterprise tools charge a fortune for and the cheap tools skip: the number you quoted has to be the number you invoice and the number that hits your books — without anyone re-typing it. That is what estimate to invoice software is supposed to buy you, and most of the time it only buys you half.
Here is the workflow in Mortar, start to finish, so you can see where the re-typing usually creeps in and where it does not.
The customer opens one link, picks options, and signs on their phone
You build the estimate on the customer’s record from a price book with your loaded costs already baked in — a few taps, not a napkin. Then you send it. The customer gets one link. They open it on the phone in the driveway, see line items and any options you offered (a good-better-best tier, an add-on, a material upgrade), pick what they want, and sign right there with a finger. No PDF to print, no scan-and-email round trip, no "did you get my quote?" three days later.
When they pick an option, the total on the page updates — because the quote is doing the math, not a spreadsheet you keep on your side. The e-sign estimate they signed is the exact document you sent, options and all, with a timestamp. You are not chasing a signature on a separate form.
Branded quotes with your logo, not ours
The quote the customer opens carries your business name, your logo, and your terms. On the Suite plan it is fully white-labeled — no Mortar footer, no "sent via" line — so as far as your customer knows, this is your software. On Solo and Core the document is still tenant-branded with your logo and details; the white-label removal of our branding is the Suite piece. Either way the customer is looking at your name on the thing they sign.
One calculation: the quote number is the invoice number is the P&L number
This is the whole point, and it is where the cheap tools fall down. In Mortar a quote total is calculated in exactly one place. The invoice is generated from the estimate the customer already signed — it is not a fresh document you re-key from the quote. Same line items, same options they chose, same total. Then when the payment clears, that same number posts to your cash-basis P&L. Quote, invoice, and books are three views of one calculation, not three copies you hope match.
Nothing reconciles wrong because nothing is computed twice
When the signed estimate says $4,200, the invoice is $4,200 and the P&L books $4,200 — because all three read the one total. No CPQ-to-billing hand-off, no re-typing the total into QuickBooks at month-end, no invoice that quietly drifted from what the customer agreed to.
That single-source rule is the same idea the whole product is built on. If you want the buyer’s-eye view of why it matters across every module, read what a field service CRM should actually do.
Deposit captured at signature
If the job needs a deposit, you can require it at signature. The customer signs and pays the deposit in the same flow, on their phone, before they close the tab. Payment runs on your own connected Stripe account — card or bank draft (ACH) — and settles directly to you. Mortar never touches the money; it sends the request and books the payment. Stripe’s standard processing fee applies, and that fee is Stripe’s, not ours.
The deposit posts against the job the moment it clears, so the balance due on the final invoice is already correct. You are not tracking "they paid half" in a text thread.
Paid, and the job marks itself done
Do the work
The signed estimate becomes the scheduled visit on Core and up, dispatched to a tech who sees it on their phone the moment it’s scheduled.
Send the invoice
It is generated from the signed estimate — same total, minus any deposit already paid. One tap to send.
Get paid
The customer pays by card or bank draft on your Stripe. The payment posts to the job and to your P&L when it clears.
The job closes
Paid moves the job to its finished, paid state on the board — you are not hunting for which invoices are still open.
For the one-off version of this loop from the customer’s side, see how to send a quote and get paid. For work that repeats — a maintenance plan or a mowing route — the same rails run recurring charges weekly, biweekly, or monthly; the mechanics are in how to bill recurring service customers.
Included in every plan, not a higher tier
The estimate-to-paid core — contacts, estimating with e-sign, invoicing, and payments on your own Stripe — is on every plan, plus a lead and job board. You do not buy the ability to sign a quote or get paid as an add-on. What the higher tiers add is the rest of the operation.
- Solo — $39/month, 1 seat. The full estimate-to-paid core plus a lead and job board. Tenant-branded documents with your logo.
- Core — $99/month, 5 seats. Adds Dispatch — scheduling and recurring service — plus the website contact form you embed on your own site, so the signed estimate turns into a scheduled visit on your calendar.
- Suite — $179/month, 15 seats. Adds bookkeeping, marketing (lead attribution, campaigns, review requests, follow-ups), and white-label documents with no Mortar branding at all.
Your field tech never sees the margin
Permissions are per person, not a plan upsell. A tech can open the job, the address, and the schedule but not the estimate margin, the finances, or the settings. The office runs the numbers; the crew runs the work.
What is estimate to invoice software?
It is software that turns a signed estimate into an invoice without re-keying the total — same line items, same options the customer chose, same number, carried straight through to payment and your books. The good ones compute the total once so the quote, invoice, and P&L never disagree.
Can the customer sign the estimate on their phone?
Yes. The customer opens one link, picks any options you offered, and signs with a finger on their phone. The signed document is the exact estimate you sent, timestamped — no PDF to print, no scan-and-email round trip.
Can I take a deposit when they sign?
Yes. You can require a deposit at signature, paid by card or bank draft (ACH) on your own Stripe account in the same flow. It posts against the job when it clears, so the final invoice balance is already correct. Stripe’s standard processing fee applies — that fee is Stripe’s, not ours.
Do I need the top plan to send e-sign estimates?
No. Estimating with e-sign, invoicing, and payments on your Stripe are on every plan, starting at Solo for $39/month. Scheduling and recurring service start on Core ($99); white-label documents with no Mortar branding are on Suite ($179).
