Invoices your customer actually reads.
Invoicing in SalesThumb is a one-tap transition from job-done to money-in. Convert any approved quote to a branded invoice, adjust if scope changed, and send a pay link over SMS or email. Your customer opens it on their phone, taps Apple Pay, and the invoice reconciles against the quote, the deposit, the appointment, and your QuickBooks ledger — automatically. No more Venmoing yourself from the customer's iPhone while the install waits. No more month-end accountant marathon. You do the work, we collect the money, the books stay clean.

Features, zoomed in
The parts that actually move the needle.
Three capabilities built specifically for the day-to-day of a working shop.
Deep dive · 01
From quote to invoice — zero re-entry
The invoice editor inherits every line from the approved quote. Deposits are pre-credited. Tax is recomputed against the current rate. The invoice number increments per shop so your bookkeeper sees a clean, gap-free series. If scope changed, add a change-order line — the customer sees the delta, not a new document. One workflow, from quote to signed invoice to paid receipt.
- Deposit auto-credited on conversion — balance reflects what's actually owed
- Change orders keep the invoice history clean, no voids needed
- Per-line tax with optional per-shop, per-class, or per-line overrides
- Tied to the appointment — hours, tech, photos all visible in one view

The invoice your customer taps once
Most of your invoices get read on a phone while standing next to their car. SalesThumb's customer pay page is designed for that moment — brand-stamped, mobile-first, with Apple Pay and Google Pay above the fold. One tap, $1,040 paid, receipt automatically sent, invoice marked paid, QuickBooks queued for tonight. No login required, no app install, no "how do I pay this?" text.
- Apple Pay / Google Pay above the fold on mobile
- Receipt sent automatically to the customer's phone + email
- Status auto-updates on your dashboard (Sent → Viewed → Paid)
- Reliable on bad Wi-Fi — works on 3G

Split payments, no spreadsheet
Deposit $200 at booking, $500 cash when the tech starts, $500 card at pickup. Every tender lands on the same invoice with method, staff member, and timestamp. Balance auto-recomputes. No reconciliation dance at end of day — your dashboard already shows the correct total and the invoice already says "Paid in full."
- Unlimited tenders per invoice
- Card, cash, check, ACH, gift-card, store-credit — all logged
- Per-tender staff attribution (who took the payment)
- Automatic balance tracking — no more "wait, what did they still owe?"

QuickBooks reconciliation, done nightly
Every paid invoice is pushed to QuickBooks Online as a sales receipt. Service categories map to GL accounts. Deposits, tips, and refunds sync on their own lines. Your accountant opens QBO on the 1st of the month and sees a clean ledger — no "what's this $471 line?" email. Xero is in beta.
- Nightly sync at 2 AM local time
- GL-account mapping per service category
- Deposits, tips, refunds sync as separate ledger lines
- Retry + audit log on every failed sync

Who it's for
Built specifically for…
- Shops still sending PDFs attached to Gmail messages
- Owners who've ever Venmoed themselves from the customer's iPhone
- Anyone whose customers "forgot" to pay and came back months later for warranty
- Tint shops that take deposits by Zelle and final by card and lose track
- Accountants who need clean QuickBooks data, not a month-end cleanup
What it replaces
The old way…
- Venmo / Zelle / Cash App screenshots for every payment
- PDFs attached to emails that land in spam
- Paper receipts you photograph and file in a drawer
- "Send me a screenshot when it goes through"
- Month-end QuickBooks reconciliation marathons
How it works
Set it up once. Run it forever.
- 1
From quote to invoice, one tap
No re-entry. Deposits carry over, line items lock in, and the invoice number increments per shop.
- 2
Send a pay link
SMS or email — customer clicks, pays, done. Every state transition (sent, viewed, paid) is logged on the invoice timeline.
- 3
Reconcile automatically
Card payments hit the invoice. Cash, check, or ACH get a manual entry. QuickBooks sync pushes paid invoices nightly.
How a shop actually uses this
You finish a $1,200 ceramic coating. The quote was approved two weeks ago with a $200 deposit. You tap Convert → the invoice appears pre-populated with the quote lines and $200 already credited. Balance due: $1,000. Text the pay link. She taps Apple Pay. Reconciled automatically.
Questions
Good to know.
- Can I customize the invoice layout?
- Yes — upload a logo, pick an accent color, choose one of three templates, and add custom footer text per shop.
- What about sales tax?
- Set tax rates per shop, per line item, or per vehicle class. Sales-tax reports roll up by month with state/county breakdowns and export to your accountant.
- How does QuickBooks sync work?
- Paid invoices sync nightly to QuickBooks Online as sales receipts. You map service categories to GL accounts once; after that, deposits, payments, tips, and refunds all flow on their own ledger lines. Xero integration is in beta.
- Can I void an invoice that's already paid?
- Yes. Voiding a paid invoice creates a credit memo and refunds the original card transaction (or marks cash/check as refunded). Full audit trail is preserved — nothing is silently deleted.
- Can one invoice be paid with multiple methods?
- Yes. A $1,200 invoice can be $200 deposit via card, $500 cash at pickup, and $500 card on the balance. Every tender is logged with method, date, and the staff member who took it. The invoice is only marked paid when the balance hits zero.
- Do I need my own Stripe account?
- Yes — we use Stripe Connect. The money flows to your Stripe account, then to your bank. We never touch your funds. Our platform fee is 0.3% on top of Stripe's normal rates, always disclosed at payment time.
